29 T.C. 878">*879 On February 24, 1955, the Commissioner determined the following deficiencies in petitioner's income tax:

In addition to allegations of error relating to the determination of deficiencies, the petition further assigns as error the Commissioner's failure to allow petitioner's claims for refund in the amounts of $ 47,289.19 and $ 515.61 for the years 1944 and 1945, respectively, and alleges overpayments in these amounts. The issues for decision are: (1) Whether petitioner's widely separated agricultural operations constituted a single trade or business, the combined losses from which are subject to the adjustments provided by section 130 of the Internal Revenue Code of 1939; (2) whether this Court has jurisdiction over the matters alleged by petitioner with regard to the refund 1958 U.S. Tax Ct. LEXIS 256">*258 claims; and (3) if the Court has jurisdiction, whether petitioner's recovery is barred by equitable estoppel arising by reason of the execution by the parties of Form 870-TS (Modified). Other issues raised by the petition were settled by stipulation or conceded at the hearing of the case.

FINDINGS OF FACT.

Some of the facts have been stipulated. The stipulation and exhibits attached thereto are incorporated herein by this reference.

Arthur V. Davis, hereinafter referred to as petitioner, is an individual who resided in Pittsburgh, Pennsylvania, during the years here in question. He kept his books and filed his income tax returns on the cash receipts and disbursements method of accounting and on a calendar year basis. His income tax returns were timely filed with the collector of internal revenue for the twenty-third district of Pennsylvania.

During the taxable years 1944 through 1949 petitioner carried on farming and livestock activities in Texas, Mexico, Florida, and the Bahama Islands, British West Indies, as sole proprietorships under various fictitious names. The books and records of these business enterprises were kept on an accrual basis.

Issue 1.

Brownsville Plantations, a proprietorship 1958 U.S. Tax Ct. LEXIS 256">*259 of petitioner, conducted its operations near Brownsville, Texas, and in the State of Tamaulipas, Mexico, 80 miles south of Brownsville. It began operations in 1944 when petitioner acquired the assets upon the liquidation of a corporation known as Castor Products Corporation of America, which 29 T.C. 878">*880 was indebted to him. Brownsville Plantations ceased operations and was terminated in 1951.

The Texas operations of Brownsville Plantations involved about 1,200 acres, of which 300 to 400 acres were allocated to cotton, 100 to 200 acres to truck or row crops, and 100 acres to citrus orchards. About 600 acres were in brush or wasteland. The truck and row crops included such items as tomatoes, corn, potatoes, broccoli, beans, peas, and cabbage. During the years in question, 2,000 new citrus trees were added to this property.

The Mexican property consisted of 7,900 acres, of which only 500 were in cultivation. During the years in question the cultivated land was utilized for cotton and some field corn. Before 1944 the cotton acreage had been utilized to grow castor beans.

Brownsville Plantations maintained a machine shop to make irrigation pumps and maintain and repair its own machinery, and an 1958 U.S. Tax Ct. LEXIS 256">*260 oil mill to process castor beans for castor oil and coconut oil and coconut waste to produce coconut oil. It did not engage in the raising of livestock.

Brownsville Plantations had 6 to 8 regular salaried employees in Texas, and 5 in Mexico. There was a general superintendent, an oil mill superintendent, and an assistant superintendent for the Mexican and Texas farm operations. At cotton picking or harvesting time, 350 to 400 people were locally recruited to work on the farms, most of whom spoke only Spanish.

Brownsville Plantations maintained its own separate set of books and records on its premises. It maintained a checking account in the First National Bank of Brownsville. Only the general superintendent and the treasurer were authorized to draw checks on this account. Brownsville Plantations had a line of credit at the same bank and borrowed money from the bank on notes signed in the proprietorship's name by the general superintendent. The name "Brownsville Plantations" appeared upon the checks, notes, and other papers of the enterprise, and upon its motor vehicles. Titles to motor vehicles were taken in the name of Brownsville Plantations.

Brownsville Plantations obtained 1958 U.S. Tax Ct. LEXIS 256">*261 all its supplies from local stores only. It marketed its crops and products at local packing sheds and cotton gins. All of its materials and supplies were purchased by its own personnel.

Three Bays Farm, situated a few miles north of the town of Rock Sound on the Island of Eleuthera in the Bahamas, was a proprietorship of petitioner. This island, one of the easternmost of the Bahamas, is narrow and approximately 100 miles long. The farm began operations in 1940 on wild land, never before fully surveyed, which was cleared by petitioner.

29 T.C. 878">*881 Prior to clearing there was a high stand of trees and low-growing brush densely covering a rocky soil with no apparent signs of previous cultivation. The climate was subtropical and while there was heavy rainfall from August through November, there was a practical drought during the rest of the year. Three Bays Farm employed the services of an agronomist to give advice with regard to the agricultural development of the land. The original "long-range program" was to develop the property for the raising of livestock and to provide pasture and fodder. Experiments were also made in the growing of other crops. Some crops such as tomatoes, pineapples, 1958 U.S. Tax Ct. LEXIS 256">*262 and bananas were known to flourish on the island.

The farm, together with a number of petitioner's other enterprises on Eleuthera, was sold to a British public corporation in 1950.

Farm operations were conducted on from 440 to 650 acres. Of this acreage, from 305 to 420 acres were devoted to fodder crops and pasture for the raising of sheep, hogs, poultry, and cattle. There were 53 acres of citrus fruit orchards, including some 3,000 orange trees, 3 acres of tropical fruits, 10 to 30 acres of pineapples, 40 to 80 acres of bananas, and occasional crops of tomatoes, potatoes, okra, and onions on an acreage ranging up to 100 acres.

The year-end inventory of livestock and the acreage devoted to fodder and pasturage was as follows:

The gross income from livestock as compared with other farm products was as follows:

Three Bays Farm employed 10 to 15 people throughout the 1958 U.S. Tax Ct. LEXIS 256">*263 year, and 150 to 200 locally recruited people at harvesttime. The farm was actively managed by a resident manager who was responsible to 29 T.C. 878">*882 the general supervisor of all of petitioner's enterprises in the Bahamas.

The products of Three Bays Farm were marketed exclusively in the Bahamas, with the exception of the pineapple crop which was sent to Miami and there sold to brokers on the best terms available.

Three Bays Farm maintained its own separate books and records in Bahamian currency. It maintained bank accounts with the Royal Bank of Canada (Nassau Branch) and the Bankers Trust Company (New York). The persons authorized to draw checks on these accounts were employees of Three Bays Farm, resident in the Bahamas. The checks carried the printed name "Three Bays Farm," and were signed by the authorized signer with the word "Attorney" in accordance with Bahamian custom. The enterprise held a # 3,000 (approximately $ 12,000) line of credit with the Royal Bank of Canada which was exercised in accordance with the practice of English banks to permit overdraft of the account within prescribed limits.

All purchases of supplies, materials, and equipment for Three Bays Farm were made by its 1958 U.S. Tax Ct. LEXIS 256">*264 own personnel. The products of the farm were marketed exclusively in the Bahamas, with the exception of the aforementioned pineapple crop.

Three Bays Packers was a commercial food-packing activity carried on as a sole proprietorship by petitioner on Eleuthera, utilizing largely foodstuffs purchased from producers on the island other than Three Bays Farm. In the year 1947, as an adjunct to the packinghouse, petitioner grew a tomato crop intended for processing at the packinghouse. Petitioner sustained and separately claimed a loss of $ 44,710.07 for that year due to the failure of the crop. Some of the employees of Three Bays Packers were also employed by Three Bays Farm.

Three Bays Packers maintained its own separate books and records in Bahamian currency. It maintained a bank account with the Royal Bank of Canada. Only the accountant was authorized to draw checks thereon. The checks carried the printed name "Three Bays Packers."

Miami Plantation was a proprietorship of petitioner engaged in the growing of pineapples at Uleta, Florida. This enterprise, which was the successor to a partnership doing business under the name of Miami Pineapple Plantations, commenced operations on June 1958 U.S. Tax Ct. LEXIS 256">*265 16, 1949, on approximately 220 acres. It employed between 29 and 43 people and was managed by a field superintendent, a sales manager, and a general supervisor.

Miami Plantation maintained its own separate books and records. It had bank accounts in its own name with the First National Bank of Miami and with the Little River Bank & Trust Company, Miami, 29 T.C. 878">*883 Florida. Only the manager of the enterprise and petitioner had authority to draw checks on these accounts. The checks were imprinted with the name and address of Miami Plantation and bore the printed name "Miami Plantation" above the signature line.

Miami Plantation purchased its supplies locally in the Miami area and through its own personnel. It marketed its pineapple crops to or through food brokers in Miami and in the northeastern and midwestern United States. From time to time it also marketed its pineapples to independent truckers.

During the period 1944 through June 30, 1949, petitioner conducted certain activities under the name of Arvida Properties. This proprietorship held and managed petitioner's business and investment real property, including the land used by the above proprietorships and the improvements thereon. Arvida 1958 U.S. Tax Ct. LEXIS 256">*266 Properties did not receive rent from any of these proprietorships for the use of such property.

On July 1, 1949, Arvida Properties was divided into two separate proprietorships, Arvida Properties -- U. S. A., which included the property used by Brownsville Plantations and Miami Plantation, and Arvida Properties -- Bahamas, which included the property used by Three Bays Farm and Three Bays Packers. The assets carried on the books of Arvida Properties used by these four proprietorships as of December 31, 1948, were as follows:

Petitioner maintained an office at Miami Plantation. From this office he kept in touch with his various enterprises by telephone and telegraph. These services were billed to the respective 1958 U.S. Tax Ct. LEXIS 256">*267 proprietorships by Miami Plantation. Petitioner also received monthly and annual statements from each enterprise. The bookkeeper employed by Miami Plantation checked the statements submitted by Brownsville Plantations, for which service Brownsville Plantations was charged $ 10 per month.

Petitioner visited Brownsville Plantations in 1947. In 1948 petitioner's accountants visited Brownsville Plantations and made changes in its bookkeeping methods. Petitioner visited the Island of Eleuthera at intervals of from 3 to 4 months.

29 T.C. 878">*884 Issues 2 and 3.

On July 29, 1948, respondent sent to petitioner a so-called 30-day letter enclosing a report of an examining revenue agent which stated that there appeared to be warranted assessments against petitioner of additional income taxes for the years 1944 and 1945 in the respective amounts of $ 113,391.61 and $ 63,486.08.

Petitioner notified respondent of his disagreement on September 13, 1948, and requested a hearing on his protest. Conferences were held on October 11, 1948, and February 10, 1949, in Pittsburgh, Pennsylvania.

As a result of these conferences a tentative agreement was reached by representatives of both petitioner and respondent to the 1958 U.S. Tax Ct. LEXIS 256">*268 effect that, if the respondent would eliminate certain adjustments to petitioner's net income for 1944 and 1945 and if the petitioner would abandon the protest of certain other adjustments, a settlement might be made on the basis of an agreed liability. ^{11958 U.S. Tax Ct. LEXIS 256">*269} The principal adjustment eliminated by respondent in each year was the limitation of the losses of Three Bays Farm to $ 50,000 pursuant to section 130, I. R. C. 1939. For the year 1944 respondent also eliminated a part of a decrease in the business losses of Brownsville Plantations represented by an item "Mexican Plantation -- loans to Mexican corporation should be considered as accounts receivable" in the amount of $ 7,407.52, and $ 3,500 of a decrease of $ 8,196.36 made by him in allowable losses on account of casualties. In 1945 the only other adjustment eliminated by respondent was the disallowance of $ 5,625 claimed on account of "Bonus to Employees." All other adjustments were conceded by petitioner.

Thereafter, on September 29, 1949, petitioner signed a proposed agreement entitled "Offer of Waiver of Restrictions on Assessment and Collection of Deficiency in Tax" on Form 870-TS (Modified), whereby he agreed to deficiencies of $ 18,805.80 and $ 2,164.27 for the years 1944 and 1945, respectively. This form contained the following paragraph:

If this proposal is accepted by or on behalf of the Commissioner, the case shall not be reopened nor shall any claim for refund be filed or prosecuted respecting the taxes for [1944 and 1945], in the absence of fraud, malfeasance, concealment or misrepresentation of material fact, or of any important mistake in mathematical calculations; and the taxpayer also agrees: (1) to make payment of the above deficiencies, together with interest as provided by law, promptly upon receipt of notice and demand from the Collector of Internal Revenue, and not to file an offer in compromise respecting such liability; and (2) upon request of the Commissioner to execute at any time a final closing 29 T.C. 878">*885 agreement as to the tax liability, on the foregoing 1958 U.S. Tax Ct. LEXIS 256">*270 basis, for said years under the provisions of section 3760 of the Internal Revenue Code.

This offer was formally accepted and the agreement executed on behalf of the respondent on October 12, 1949, by Charles R. Turner, Head, Eastern Division, Technical Staff.

On September 26, 1949, in a letter to a deputy commissioner, the Chief Counsel of the then Bureau of Internal Revenue stated that upon his interpretation of the statute and various court decisions the limitation contained in section 12 (c) (2) (the successor to section 12 (g)) "should not be applied against an amount less than statutory net income (including net long-term capital gains) when computing the alternative tax under section 117 (c) (2)." This letter was never published. In arriving at the amount of the agreed deficiencies for 1944 and 1945, respondent did not apply the 90 per cent ceiling rate limitation provisions of section 12 (g) in computing the partial tax involved in the computation of petitioner's alternative taxes under section 117 (c), and the petitioner's long-term capital gains were consequently taxed at a rate in excess of the 50 per cent maximum provided by section 117 (c).

The method of applying the 90 1958 U.S. Tax Ct. LEXIS 256">*271 per cent limitation in computing the petitioner's alternative tax under section 117 (c) for 1944 and 1945 or the correct rates to use in computing his partial tax on his ordinary net income for those years was never in issue or discussed between the representatives of the parties, and the representatives of the petitioner never claimed that the said computation was incorrect until after the execution of the agreement on Form 870-TS (Modified) on October 12, 1949.

With respect to the taxable years 1944 and 1945, the petitioner and the respondent entered into a timely agreement or a series of timely agreements, on Treasury Department Form 872, extending to June 30, 1950, the period of limitation upon the assessment of income taxes. On June 30, 1950, the period expired within which the Commissioner could assess income taxes against the petitioner with respect to the taxable years 1944 and 1945, except to the extent that such taxes may be properly assessed under the provisions of section 130 of the Internal Revenue Code of 1939 if and to the extent that such section is applicable.

Petitioner and his counsel did not become aware of the problem incident to the section 12 (g) limitation until 1958 U.S. Tax Ct. LEXIS 256">*272 after the filing of his 1949 tax return. On the basis of this section, petitioner, on December 21, 1950, timely filed with the collector of internal revenue for the twenty-third district of Pennsylvania claims for refund of income taxes paid for the years 1944 and 1945 in the amounts of $ 47,289.19 and $ 515.61, respectively. On January 26, 1951, petitioner filed timely claims for refund for the years 1948 and 1949 in the amounts 29 T.C. 878">*886 of $ 75,982.04 and $ 28,763.50, respectively. In June 1952 the Court of Claims handed down its decision in Merrill v. United States, 105 F. Supp. 379">105 F. Supp. 379, denying respondent's interpretation of the statute.

In the present notice of deficiency, the respondent made the computation of petitioner's income tax liability for the years 1948 and 1949 in accordance with the method requested by petitioner in his refund claims for those years and approved by the Court of Claims. In computing the proposed deficiencies for the years 1944 and 1945, respondent did not so apply the 90 per cent limitation contained in section 12 (g).

OPINION.

Three questions are presented by the instant case for our decision. All are questions of first impression. Two of them involve an interpretation 1958 U.S. Tax Ct. LEXIS 256">*273 of section 130, I. R. C. 1939. This we set out in the margin hereof, together with the pertinent parts of respondent's regulations dealing therewith. ^{21958 U.S. Tax Ct. LEXIS 256">*274 1958 U.S. Tax Ct. LEXIS 256">*275 1958 U.S. Tax Ct. LEXIS 256">*276}

29 T.C. 878">*887 Issue 1.

The first issue arises by reason of respondent's determination that petitioner's "agricultural activities [i. e., the activities 1958 U.S. Tax Ct. LEXIS 256">*277 of petitioner carried on by the proprietorships described in our findings] constitute one trade or business, and the losses * * * claimed to have been sustained in that business * * * are allowable only to the extent of $ 50,000, as provided by Section 130 of the Internal Revenue Code of 1939, as amended."

Both parties are in agreement that the crucial question under this issue is whether petitioner's agricultural activities carried on by him under the name of Brownsville Plantations and those carried on under the name of Three Bays Farm constituted one business or two several businesses. If they constitute two several businesses then, under respondent's own regulations, the deductions attributable to them "shall not be aggregated in determining whether the deductions * * * exceed the gross income derived from such trades or businesses by more than $ 50,000 in any taxable year." Section 130 is only applicable to the instant case if the deductions of Brownsville Plantations and Three Bays Farm are aggregated.

Counsel for both petitioner and respondent have filed herein voluminous, thorough, and extremely well written briefs, and it would be impractical and perhaps unfair to the parties 1958 U.S. Tax Ct. LEXIS 256">*278 to rephrase in our own language and compress into a necessarily short summary a complete resume of all the arguments advanced on this issue. Accordingly we quote directly from the briefs, summaries prepared by the parties themselves of their respective positions on this issue. Respondent states his position as follows:

Farming activities which are the same or substantially similar in nature constitute a single trade or business even where conducted at more than one location. The term "business", as used in the Internal Revenue Code of 1939 and earlier Revenue Acts, means "line of business" and is somewhat interchangeable with the word "trade". Petitioner's farming activities, although variously located, were the same or substantially similar in nature. They consisted of diversified farming operations under similar climatic and soil conditions and involved many common farm products and other products which, though not produced at all locations, were interrelated with the common products 29 T.C. 878">*888 because of the diversified nature of the operation. Because of this, it is immaterial whether the operations were separately conducted. In any event, petitioner's farm activities were not separately 1958 U.S. Tax Ct. LEXIS 256">*279 conducted.

In a rebuttal memorandum he restates his position as follows:

Our principal position is, of course, that the "nature test" is controlling, that substance rather than form should control. Our alternative position (in case the Court rejects the nature test or decides that petitioner's various farms differ in their nature) is that two or more business ventures, though differing in nature, will still constitute a single trade or business, unless they are separately conducted for a bona fide business purpose. * * *

Petitioner's contention is outlined by him as follows:

Each of the four enterprises involved was a separate trade or business, and they may not be treated as a single trade or business for the purposes of section 130.

1. The statute and regulations show that the limitations on deductions prescribed by section 130 are to be applied separately to each trade or business conducted by a taxpayer.

2. The enterprises in question were in fact separately and independently conducted and were not materially interrelated.

3. Under the authorities each of these four enterprises was a separate trade or business.

Upon the proposition that Three Bays Farm and Brownsville Plantations were 1958 U.S. Tax Ct. LEXIS 256">*280 separately conducted and not materially interrelated, petitioner further summarizes his position as follows:

by reason of their very great geographical separation, their completely independent management and personnel, their separate origins and endings, the differences in their products, labor sources, markets, sources of supplies, and financial and economic problems, and their separate, unrelated and independent books of account, bank accounts, purchasing, selling, borrowing and dealings with outsiders, Brownsville Plantations and Three Bays Farm were separate, independent and unrelated enterprises having no connection whatever with each other except that both were owned by the petitioner. * * *

The legislative history of section 130 (sometimes referred to as the "hobby amendment" and sometimes as the "Marshall Field amendment") is not helpful in a consideration of the problem here presented. The ingenious attempts of the parties to draw pertinent analogies from other sections of the Revenue Code and from decided cases have only confirmed us in the view that this question is one of first impression.

Since it is a question of first impression, it is important that we confine our decision 1958 U.S. Tax Ct. LEXIS 256">*281 to the facts before us and not attempt in this Opinion to consider all of the hypothetical questions that might come to mind in a consideration of the problem of what constitutes a separate business.

Respondent recognizes, as his regulations require, that an individual may have several separate businesses. This necessarily implies that the common ownership of these businesses and the exercise with regard 29 T.C. 878">*889 thereto of the rights of ownership do not ipso facto convert them into one business. Respondent also recognizes, although reluctantly, that not all agricultural activities necessarily constitute a single business. We would assume that under ordinary circumstances of separate management and operation a man who raises potatoes in Maine, cotton in Albama, cattle in Texas, and timber in Oregon would be carrying on four different businesses, even though they would all be classified generically as agricultural activities. Respondent would contend, however, that a man raising potatoes on a farm in Maine and also raising potatoes on a farm in Idaho would be carrying on only one business regardless of the fact that the operations on each farm were conducted separately, and also that a man 1958 U.S. Tax Ct. LEXIS 256">*282 raising cotton on a farm in Alabama and cattle on a ranch in Texas was carrying on one business if there was a common management of the two farms.

Petitioner recognizes that the mere fact that two farms or agricultural activities are physically separated does not necessarily result in their operations constituting two businesses. He would concede that if one farm owned by a taxpayer were used for the running and pasture of hogs and another farm also owned by him were used for the production of feed for these hogs, the operation of both farms might be considered as one business even though they were physically separated and each farm had its own resident manager. In the supposed case there would be sufficient economic interrelation between the operation of the two farms to justify the conclusion that as a practical matter there was one business unit. Petitioner does contend, however, that under the facts of the instant case the geographical separation of the two agricultural activities is an important factor in considering whether as a practical matter they constituted one business unit.

In arguing that the petitioner's agricultural activities at Three Bays Farm and at Brownsville 1958 U.S. Tax Ct. LEXIS 256">*283 Plantations were substantially similar in nature, respondent contends that "[the] climatic and soil conditions under which each was conducted were generally similar," both being "subtropical areas, with dry and rainy seasons," and that "[the] general picture presented is that of two diversified farming operations" with inconsequential differences arising because in each of the two farming operations petitioner "put some emphasis on products which would sell in local markets."

Respondent bases his contention that the soil and climate of Three Bays Farm and Brownsville Plantations were substantially similar largely upon the fact that the nature of the crops raised on Three Bays Farm and Brownsville Plantations was substantially similar, pointing out that on both there were citrus trees and that tomatoes, 29 T.C. 878">*890 potatoes, and corn were grown on each. He recognizes that on Three Bays Farm petitioner raised bananas, avocados, and pineapples which were not grown on Brownsville Plantations, and on the latter he grew beans, broccoli, peas, and cabbage which were not grown on the former; and he further recognizes that cotton was raised only on Brownsville Plantations and livestock only on Three 1958 U.S. Tax Ct. LEXIS 256">*284 Bays Farm. However, respondent contends that the cotton crop at Brownsville, although representing 58 per cent of the sales of that agricultural activity, and the raising of livestock at Three Bays Farm, although supported by over one-third of the acreage used in that operation, were not so important as to prevent both enterprises from being classified as diversified farming operations generally similar in nature. We are not shown by the record the season of the year when the various row crops were planted and harvested by each of the two proprietorships.

While the climate (with regard to average temperature) may be generally similar at the locations of both proprietorships, we are unable to conclude that the soil and climate (including the amount and incidence of precipitation) of both were so substantially similar as to constitute an important factor persuasive of a finding that the two agricultural activities themselves were substantially similar.

Contrary to the views of the respondent, we are more impressed by the differences between the two agricultural enterprises here in question than by their points of similarity. It is true that both were on approximately the same degree 1958 U.S. Tax Ct. LEXIS 256">*285 of latitude, that upon both some citrus trees were planted, and that upon both tomatoes, potatoes, and corn were grown. However, there were more differences than similarities with regard to the so-called row crops raised on each, and, furthermore, there was an important difference with regard to the primary activity in each enterprise. At the Brownsville Plantations the primary activity was the raising of cotton. This was not raised as a part of a program for rotation of crops characteristic of a diversified farming operation, but constituted the principal crop throughout the taxable period. At Three Bays Farm we are persuaded by the record that the initial emphasis was placed upon a program calling for the raising of livestock and the development there of adequate pasturage and production of fodder. It appears from the employment there of agronomists who were specialists in tropical agriculture (a circumstance not existing in connection with the Brownsville Plantations), and from a decrease in the number of livestock and in acres devoted to pasture and the raising of fodder that the emphasis shifted from livestock to the experimental development of tropical fruits and vegetables. 1958 U.S. Tax Ct. LEXIS 256">*286 In our opinion the two proprietorships did not constitute substantially similar diversified farming activities.

29 T.C. 878">*891 With regard to the acquisition of materials and supplies, the marketing of products, and matters connected with transportation, labor, and financing, the operations were strikingly different. On the entire record we conclude that the agricultural activities carried on by petitioner at Three Bays Farm, and those carried on by him at Brownsville Plantations were not substantially similar.

Respondent further argues that even if we conclude that the two agricultural enterprises differed in nature they must still be considered as a single trade or business since they were not separately conducted for a bona fide business purpose. Respondent points to the common supervision of petitioner over both, the appearance of the assets of both on the books of Arvida, and the fact that books kept by petitioner for Three Bays Farm do not completely reflect the operations of that enterprise but must be read in connection with the books of Arvida.

We have no doubt in our conclusion that the two agricultural enterprises were conducted by petitioner as separate businesses and for very good business 1958 U.S. Tax Ct. LEXIS 256">*287 reasons. Of course, petitioner, as the owner of both, exercised over both the supervision and control which a prudent owner would be expected to exercise, but respondent himself recognizes that common ownership does not preclude the existence of several separate businesses. While technically incomplete, separate books were kept for both Three Bays Farm and Brownsville Plantations, which adequately reflected their operational results. Each had separate operational management and, in the practical operation of each, there was no connection with the other. This separateness of operations was called for by the circumstances. The two enterprises were located far distant from each other, they were in different countries with different conditions relating to finances, currency controls, labor, and marketing, and the agricultural problems themselves differed as between the two enterprises. Under the existing circumstances it is difficult to see how they could have been conducted as a unit. Certainly the fact that they were not so conducted cannot be ascribed to any lack of bona fides on the part of petitioner.

On the assumption, arguendo, that the tests laid down by respondent are controlling, 1958 U.S. Tax Ct. LEXIS 256">*288 we nevertheless conclude that the agricultural activities carried on by petitioner under the names of Three Bays Farm and of Brownsville Plantations constituted two separate businesses, and that their losses cannot be aggregated under section 130 of the Internal Revenue Code of 1939.

If we apply to this problem the test suggested by petitioner, that is, whether there is a practical economic interrelation between the two agricultural enterprises, it is obvious that we should arrive at the same result. While this test appears to have much to commend it, it is unnecessary for us to decide whether it or the tests suggested by respondent 29 T.C. 878">*892 should control our decision herein, since even assuming the pertinence of those suggested by respondent the facts of the instant case require a conclusion on this issue in favor of petitioner.

Issue 2.

This issue involves the refund claims submitted by petitioner for the years 1944 and 1945. In October 1949 respondent accepted petitioner's "Offer of Waiver of Restrictions on Assessment and Collection of Deficiency in Tax" (Form 870-TS (Modified)), in which petitioner agreed to deficiencies of $ 18,805.80 and $ 2,164.27 in 1944 and 1945, respectively. The 1958 U.S. Tax Ct. LEXIS 256">*289 agreed-upon deficiencies were thereafter paid. In December 1950 and January 1951 petitioner timely filed claims for refund for the years 1944, 1945, 1948, and 1949 on the ground that the 90 per cent limitation contained in section 12 (g) (later section 12 (c)), ³ had not been applied when the respective deficiencies for 1944 through 1949 had been calculated. In his deficiency notice respondent has taken this limitation into account in the recalculation of the deficiencies determined for 1948 and 1949, but has failed to do so in the recalculation of the deficiencies determined for 1944 and 1945. In his petition, petitioner has assigned as error this failure to apply the section 12 (g) limitation, and has asked this Court to determine overpayments of taxes for those years on account thereof.

The question for our decision under this issue is whether this Court has jurisdiction over the claims of overpayments made by petitioner for those years. Both parties agree that the period of limitation on assessment and collection of deficiencies in income tax, prescribed by section 275, has run for the years 1944 and 1958 U.S. Tax Ct. LEXIS 256">*290 1945. Petitioner points out that subsections (b) and (c) of section 130 permit the determination of a deficiency which is otherwise barred by section 275. He argues that section 130 makes no provision for the jurisdiction of this Court over proceedings relating to determinations of deficiencies made thereunder, and necessarily assumes that such determinations shall be covered with regard to procedure and jurisdiction by sections 272 and 322, even though the statute of limitations contained in section 275 has run. Thus, petitioner argues that the determination of a deficiency involved in a section 130 proceeding should be considered, for jurisdictional and procedural purposes, the same as any other timely determination of a deficiency, and, consequently, section 322, including subsection (d) which gives this Court jurisdiction to determine the amount of any overpayment, is applicable herein.

Respondent, on the other hand, contends that section 130 (b) and (c) gives this Court jurisdiction only over the proposed deficiencies 29 T.C. 878">*893 arising out of section 130 (a). He argues that if the assessments of any deficiencies for the years in question are barred by the statute of limitations, the 1958 U.S. Tax Ct. LEXIS 256">*291 extension contained in section 130 (b) and (c) is limited to the section 130 (a) deficiency and the same limitation applies to claims of overpayment. In the alternative, respondent contends that the doctrine of equitable estoppel precludes our holding for petitioner on this issue. This alternative contention is discussed under Issue 3.

The parties have not called our attention to and we have been unable to discover any decided case dealing with this question. Nor do the committee reports shed any light on the subject. It is our opinion, however, that petitioner is correct.

Section 130 (b) and (c) provides that any deficiency determined to be due under section 130 (a) shall be assessed within 1 year after the expiration of the period for assessment of the fifth taxable year. The effect of section 130 (b) and (c) is to extend the statute of limitations on assessment of a deficiency computed under subsection (a). It does not provide for any special procedure. It does not purport of itself to grant jurisdiction to this Court or limit this Court's jurisdiction. Neither does it authorize respondent to send a notice of a deficiency determined thereunder. To determine jurisdictional and 1958 U.S. Tax Ct. LEXIS 256">*292 procedural questions relating to determinations of deficiencies, we must turn to supplements L and O, subchapter C, of chapter 1, I. R. C. 1939. The procedures to be followed by the respondent in determining a deficiency and the procedures to be followed by petitioner in invoking the jurisdiction of this Court are carefully set forth in sections 272 and 322. The notice of deficiency, which is the basis of this action, must be considered as having been "mailed to the taxpayer * * * under section 272 (a)." No other section of the Code could authorize such mailing. The only jurisdictional requirement necessary to fall within these sections is filing a timely petition after the receipt of a timely notice of the determination of deficiency. If Congress thought section 130 warranted separate procedures for assessment and review, it could have made provision for such procedures as was done in section 732 with respect to the excess profits tax. This Court's jurisdiction over refund claims and overpayments where a petition has been filed by the taxpayer is authorized by section 322. There is no exception stated for cases where the Court's jurisdiction is invoked in connection with a determination 1958 U.S. Tax Ct. LEXIS 256">*293 of deficiency made pursuant to section 130. The only pertinent requirements contained in section 322 are a timely petition to this Court based on a timely notice of deficiency under section 272, and a claim for refund timely filed by petitioner within the period prescribed by section 322 (d). In the instant proceeding these requirements have been met. The notice of deficiency was made timely by the extension of the statute 29 T.C. 878">*894 of limitations, contained in section 275, by section 130 (c). The petition was timely filed pursuant to section 272 (a) (1). The refund claim was filed within the period set forth in section 322 (d). Under these circumstances we believe petitioner is not barred from pursuing his refund claim. In view of the above statutory provisions, we hold that this Court has jurisdiction to determine the questions of overpayment herein raised.

Issue 3.

This issue deals with respondent's alternative contention under Issue 2, i. e., that if this Court has jurisdiction to determine the merits of the refund claims for the years 1944 and 1945 then petitioner is estopped from recovering under these claims through the operation of the doctrine of equitable estoppel. Respondent 1958 U.S. Tax Ct. LEXIS 256">*294 points out that petitioner stated that he would not file any refund claims when he made an offer of waiver on Form 870-TS. ⁴ Respondent argues that his acceptance of this offer of waiver was based at least partly on this statement and that he suffered a detriment by allowing the statute of limitations to run without assessing any further deficiency in reliance on the agreement contained in the Form 870-TS.

The parties are agreed that the execution of a Form 870-TS is not equivalent to the execution of a closing agreement and is not of itself binding upon the parties. See Botany Worsted Mills v. United States, 278 U.S. 282">278 U.S. 282. Obviously respondent could not contend to the contrary since he has himself disregarded his "acceptance" of the "Offer of Waiver of Restrictions on Assessment and Collection of Deficiency in Tax" by determining the deficiencies for 1944 and 1945 here involved. Only by the application of the doctrine of estoppel may the petitioner be precluded from successfully contending here that overpayments be determined for these 2 years pursuant to his refund 1958 U.S. Tax Ct. LEXIS 256">*295 claims that the limitation provisions of section 12 (g) were improperly applied in arriving at the amounts of the agreed deficiencies for those years. The merits of this question were decided in Merrill v. United States, 105 F. Supp. 379">105 F. Supp. 379, and respondent in effect concedes it as indicated by his computation of petitioner's income tax liability for the years 1948 and 1949 in accordance with the method requested by petitioner in his refund claims for 1944 and 1945.

The allegations of respondent's answer, which present this issue of estoppel, are simply to the effect that respondent's agent directed a letter to petitioner stating that assessments of additional income taxes for 1944 and 1945 seemed warranted; that petitioner "indicated his disagreement with several of the proposed adjustments contained therein"; that at a conference between the parties it was tentatively agreed that if respondent "would eliminate certain adjustments" and 29 T.C. 878">*895 petitioner would "abandon protestation of certain other adjustments" the case might be disposed of "on the basis of an agreed liability"; that thereafter an agreement was reached and Form 870-TS was executed; "[that] on June 30, 1950, the period expired 1958 U.S. Tax Ct. LEXIS 256">*296 within which the Commissioner could assess income taxes against the petitioner with respect to the taxable years 1944 and 1945"; and "[that] the petitioner should be held to be estopped to assert and prosecute the aforesaid claims for overpayment."

Among the elements necessary to the establishment of estoppel is a misrepresentation of fact on the part of the person sought to be estopped, a justified reliance upon that misrepresentation by the person to whom it is made, and a detriment sustained by the latter. We doubt that petitioner's undertaking in a document similar to Form 870-TS not to file or prosecute claims for refund, which was not legally binding on him and was known by respondent not to be an enforceable obligation, could be considered as a misrepresentation of fact upon which respondent could justifiably rely or did rely. We pass these elements, however, and address ourselves to the element of detriment on the part of respondent.

The detriment shown in this proceeding is merely the running of the statute of limitations with regard to possible additional deficiencies relating to the years 1944 and 1945. We are not informed as to what those deficiencies, if any, might have 1958 U.S. Tax Ct. LEXIS 256">*297 been. It is true that some concessions were made by respondent in arriving at the agreed deficiencies set forth in the Form 870-TS, but we may not assume that they were made improvidently or without full legal and factual justification. No indication is given that any recoupments with regard to the claims for overpayment are urged by respondent, although our decision on the second issue that we have jurisdiction over petitioner's claims for overpayment for 1944 and 1945 would necessarily result in our having jurisdiction over claims of recoupment even though relating to matters barred, so far as a determination of deficiency is concerned, by the statute of limitations.

Respondent relies on Guggenheim v. United States, 77 F. Supp. 186">77 F. Supp. 186, certiorari denied 335 U.S. 908">335 U.S. 908, and also points to the following cases indicating a similar result: Baldwin v. Higgins, not officially reported (S. D. N. Y., 1937; 19 A. F. T. R. 1341, 37-2U. S. T. C. par. 9434), affirmed on other grounds 100 F.2d 405; Schneider v. Kelm, 137 F. Supp. 871">137 F. Supp. 871, affirmed on other grounds 237 F.2d 721; Girard v. Gill, 142 F. Supp. 770">142 F. Supp. 770, affirmed per curiam 243 F.2d 166; and Daugette v. Patterson,    F. Supp.    (N. D. Ala., 1956), 1958 U.S. Tax Ct. LEXIS 256">*298 affd. 250 F.2d 753 (C. A. 5, 1957).

These cases appear to be contrary, at least in reasoning and language, to the following cases cited to us by petitioner: Joyce v. Gentsch, 141 F.2d 891; Steiden Stores, Inc. v. Glenn, 94 F. Supp. 712">94 F. Supp. 712; 29 T.C. 878">*896 Cuba Railroad Company v. United States, 124 F. Supp. 182">124 F. Supp. 182; and John v. United States, 138 F. Supp. 89">138 F. Supp. 89.

We are not aware of any opinions of this Court directly concerned with the question here presented.

It may be pointed out that the cases relied upon by respondent differ factually from the instant case in that here the proceeding was precipitated by respondent's determination of a deficiency in disregard of his acceptance of Form 870-TS; and petitioner's claims of overpayment, although based on claims for refund filed before such determination, were asserted as part of a petition predicated on the notice of such determination. While this factual difference may be pertinent in a consideration of the general equities of the problem, we do not rest our conclusion upon it.

We also point out that actions brought in the Federal District Courts to recover taxes erroneously paid are equitable in function and governed by equitable principles. See Stone v. White, 301 U.S. 532">301 U.S. 532. 1958 U.S. Tax Ct. LEXIS 256">*299 The jurisdiction of this tribunal is strictly statutory; it has no equitable jurisdiction. C. D. Little, 20 B. T. A. 1042.

We also point out that we do not consider 77 F. Supp. 186">Guggenheim v. United States, supra, distinguishable from Joyce v. Gentsch, supra, on account of the fact that the latter case was concerned with a waiver containing a clause expressly reserving the right to respondent to assess a further deficiency. Even without that clause, as in the instant case, the respondent would have such a right.

Upon the record here presented, we conclude that there is not a sufficient showing of detriment on the part of respondent as to justify a holding that the doctrine of equitable estoppel precludes petitioner from establishing his claims of overpayment relating to the years 1944 and 1945. It is clear that the respondent who has pleaded estoppel has the burden of demonstrating the existence of all the elements of estoppel, including detriment. Helvering v. Brooklyn City R. Co., 72 F.2d 274. In our opinion the detriment shown must be real and substantial. See 31 C. J. S. 275. It is not enough to show that in reliance on petitioner's statement of his unenforceable undertaking that he would 1958 U.S. Tax Ct. LEXIS 256">*300 not file or prosecute any claim for refund respondent permitted the period of limitations to run on possible hypothetical deficiencies characterized only in general language. He must show that as a result of his reliance upon petitioner's "statement" the period of limitations was permitted to run on specific items of additional tax which he in good faith considers to have been possible to collect as of the time of the execution of Form 870-TS, the barring of which by the statute of limitations will result in a real loss to the Treasury. Furthermore, it must be demonstrated that the claims for additional taxes (with regard to which he is barred from determining deficiencies) are either not available as recoupments or 29 T.C. 878">*897 setoffs to petitioner's claims for overpayment or are in amounts larger than petitioner's claims. See Joyce v. Gentsch, supra;124 F. Supp. 182">Cuba Railroad Company v. United States, supra.

In the instant case the respondent, in spite of the execution of Form 870-TS, has determined deficiencies against petitioner for the years 1944 and 1945. The ground of the deficiencies, while not identical with, is in general subject matter similar to an adjustment considered and eliminated by 1958 U.S. Tax Ct. LEXIS 256">*301 him in connection with the execution of Form 870-TS, i. e., the application of section 130 to petitioner's claimed business losses. Petitioner's claims for refund and claims for overpayment herein relate to a matter never considered by the parties in connection with the negotiations leading to the execution of Form 870-TS, and are concededly correct. Petitioner does not here contest any adjustments made in his income tax liability for those years as a result of those negotiations. He stands by the adjustments he agreed to. Those adjustments have been made a part of the deficiency notice herein and are not put in issue by the petition, and are in no way connected with the claims for refund filed by petitioner.

Under these circumstances and in view of the lack of showing of any substantial detriment suffered by respondent, we are not inclined to stretch an equitable doctrine such as estoppel in such a way as to make a legally unenforceable document such as Form 870-TS so binding upon one party (the petitioner) as to preclude him from asserting a concededly correct claim of overpayment relating to a matter never considered in the negotiations leading to the execution of Form 870-TS 1958 U.S. Tax Ct. LEXIS 256">*302 in a proceeding precipitated by the issuance of a notice of deficiency by the other party (the respondent).

In view of our opinion upon the question of estoppel, it is unnecessary for us to consider petitioner's contention that the execution of Form 870-TS was not effective in that the matters presented by his claims for refund were the results of an "important mistake in mathematical calculations."

Decision will be entered under Rule 50.

Pierce, J., dissenting: I respectfully dissent from holdings of the majority as to the taxable years 1944 and 1945, which holdings are to the effect:

(1) That, upon the appeal of the petitioner from a notice that his 1944 and 1945 taxes were to be adjusted under section 130, this Court acquired jurisdiction to entirely redetermine the tax liabilities for said years, and to find that there are overpayments of tax -- notwithstanding that the tax liabilities for said years had been "previously determined" by compromise; that adjustments under section 130 are authorized 29 T.C. 878">*898 to be made only with respect to particular loss items which had entered into the computation of "the tax previously determined"; and that the petitioner's claim to overpayments is 1958 U.S. Tax Ct. LEXIS 256">*303 based on other items wholly unrelated to the application of section 130.

(2) That the petitioner's claim to overpayments for said years is not barred by the statute of limitations, on the ground that the period of limitation provided by section 275 was extended by the provisions of section 130 (c).

(3) That petitioner's claim to overpayments should not be denied by application of equitable estoppel -- notwithstanding that petitioner had in 1949 entered into a compromise settlement of all pending controversies respecting the years 1944 and 1945; that he had voluntarily paid the amounts of tax so agreed upon; that he had agreed the cases would be closed and no claim for refund would be prosecuted; and that, by reason of such compromise settlement, the period of limitation was allowed to expire, within which respondent could have assessed any deficiency in respect of the matters compromised.

I would have decided all the above issues, contrary to the holdings of the majority, solely on the basis of the stipulation of facts (paragraphs 11-24) and the pleadings, including petitioner's admissions in his reply to certain affirmative allegations in the respondent's answer. My reasons for this 1958 U.S. Tax Ct. LEXIS 256">*304 are summarized as follows:

I. Re Jurisdiction.

The jurisdiction of this Court to redetermine deficiencies and find overpayments in respect to income taxes for the years 1944 and 1945, is conferred and limited by sections 272 and 322 (d) of the 1939 Code. Section 272 (a) authorizes the Commissioner to determine and give notice to any taxpayer of "a deficiency determined in respect of the tax imposed by this chapter [Chapter 1 -- Income Tax]"; and it also permits the taxpayer to file a petition with this Court for redetermination of such "deficiency." Section 272 (e) gives this Court jurisdiction to redetermine the correct amount of such "deficiency," even if the amount so redetermined is greater than the amount determined by the Commissioner, and also to determine whether any penalty, additional amount, or addition to the tax should be assessed, if timely claim therefor is asserted by the Commissioner. And section 322 (d) provides, in substance, that if this Court finds there is no "deficiency" and further finds that the taxpayer has made an overpayment of tax in respect of the year for which the Commissioner determined the "deficiency," it shall have jurisdiction to determine the amount 1958 U.S. Tax Ct. LEXIS 256">*305 of such overpayment.

It is particularly significant that the term "deficiency," as used in all of said sections which confer jurisdiction on this Court, is defined to mean the amount by which: (A) The tax imposed by this chapter29 T.C. 878">*899 (Chapter 1 -- Income Tax) -- that is to say, the correct liability as fixed by the provisions of the statute -- exceeds (B) the amount of tax shown on the taxpayer's return, if any, plus any amounts assessed (or collected without assessment) as a deficiency, over the amount of any rebates made. Such a "deficiency" -- which is measured on the one hand by reference to the correct statutory tax liability, and which is measured on the other hand by the amounts of tax shown on the return, after adjustment for certain assessments, collections, and rebates -- is the type of deficiency which is referred to in the applicable Treasury regulations (Regs. 111, sec. 29.130-1 (c)), as an "actual deficiency as defined in section 271." It is only where the Commissioner has determined and given notice of such an "actual deficiency," that this Court is given jurisdiction under sections 272 and 322 (d) to redetermine the correct amount of the statutory liability and to find 1958 U.S. Tax Ct. LEXIS 256">*306 any overpayment of tax.

On the other hand, any increase in tax computed under section 130, which is therein authorized to be assessed for any year in respect of which other assessments are barred by the statute of limitations or otherwise (such as the years 1944 and 1945 here involved), is not an "actual deficiency as defined in section 271." Section 130 shows that such increase in tax is computed, not by adjusting all items of gross income and deductions (including such items as capital gains, charitable contributions, and salaries) which enter into the correct statutory liability, but, rather, by adjusting only particular losses attributable to a trade or business, which had previously been allowed in amounts of more than $ 50,000. Also, after such limited adjustment has been made, the increase in tax authorized to be assessed, under section 130, is measured not by reference to the correct statutory liability in respect of all items entering into the net income, but only by reference to "the tax previously determined" for the year involved.

Moreover, section 130 (b) does not designate such increase in tax to be an actual "deficiency," as defined in section 271; but, rather, it provides 1958 U.S. Tax Ct. LEXIS 256">*307 that such increase in tax "shall be considered" a deficiency "for the purposes of this section [section 130]." The applicable regulations (Regs. 111, sec. 29.130-1 (c)) state:

the excess of the tax recomputed as described in subsection (b) over the tax previously determined may be assessed and collected even though in fact there is no actual deficiency, as defined in section 271, in respect of the given taxable year. [Emphasis supplied.]

Thus the Commissioner is not authorized by section 130 to make any adjustment, except the limited adjustment specifically provided therein with regard to certain business losses; no provision is made for issuance of a statutory notice respecting such limited adjustment; and no provision is made that, when a limited adjustment has been 29 T.C. 878">*900 determined under section 130, this Court shall have jurisdiction to redetermine either the correct statutory liability or "the tax previously determined," or to find any overpayment of tax. The situation is otherwise where the section 130 adjustment is made for a taxable year in respect to which assessments are not barred by limitation and could be made "without regard to section 130" (such as petitioner's years 1946 1958 U.S. Tax Ct. LEXIS 256">*308 through 1949 which were open on waiver extending to June 30, 1955); for in such situation, the adjustment of losses attributable to a trade or business may be made along with other adjustments, in determining any "actual deficiency as defined in section 271" (Regs. 111, sec. 29.130-1 (c)).

The notice of deficiency in the present case served a double purpose. Insofar as it pertained to the years 1946 through 1949 which were open under waiver of the statute of limitations, it gave notice of "actual deficiencies" determined by merging the section 130 adjustments with the other miscellaneous adjustments, in the manner above mentioned; but insofar as it pertained to the years 1944 and 1945, it gave notice of increases in tax which were based only on the limited adjustments authorized to be made under section 130. The parties have stipulated (paragraph 24) that "the other adjustments reflected and explained by the statutory notice of deficiency with respect to the petitioner's income and deductions for the taxable years 1944 and 1945 * * * represent those adjustments agreed to by the petitioner and the respondent [in the compromise settlement of 1949] * * *." The taxpayer's petition, on 1958 U.S. Tax Ct. LEXIS 256">*309 the other hand, shows that his claim to overpayments is based on an item respecting the computation of capital gains, which is an item wholly unrelated to the limited adjustments authorized to be made under section 130.

On the basis of all the foregoing, I would have held that this Court has no jurisdiction to entertain or allow petitioner's claim to overpayments for the years 1944 and 1945. Whether such jurisdiction should be given to this Court, or be left to other courts, is a matter of policy controlled by Congress.

II. Re Statute of Limitations.

The majority of the Court held, near the end of that portion of its Opinion which is designated as Issue 2, that petitioner's claim to overpayments is not barred by limitation, because the statute of limitations contained in section 275 was extended by section 130 (c). I am unable to agree.

Section 275 provides a general period of limitation on assessment, which is "three years after the return was filed"; but this is expressly made subject to the exceptions contained in section 276. This latter section, so far as here material, provides:

29 T.C. 878">*901 SEC. 276. SAME -- EXCEPTIONS.

(b) Waiver. -- Where before the expiration of the time prescribed in 1958 U.S. Tax Ct. LEXIS 256">*310 section 275 for the assessment of the tax, both the Commissioner and the taxpayer have consented in writing to its assessment after such time, the tax may be assessed at any time prior to the expiration of the period agreed upon. The period so agreed upon may be extended by subsequent agreements in writing made before the expiration of the period previously agreed upon.

In the instant case, it has been stipulated (paragraph 20) that, "[on] June 30, 1950, the period [as extended by waivers] expired within which the Commissioner could assess income taxes against the petitioner with respect to the taxable years 1944 and 1945, except to the extent that such taxes may be properly assessed under the provisions of section 130 of the Internal Revenue Code of 1939 if and to the extent that such section is applicable."

Section 130 contains no provision for extension of the period of limitation provided in section 275. To the contrary, it recognizes that "any increase in the tax previously determined," which is therein authorized to be assessed, may be prevented "by the operation of any law or rule of law." And it therefore provides, in subsection (c), for a special period of limitation for assessing 1958 U.S. Tax Ct. LEXIS 256">*311 such "increase." Such special period is not measured from the date of the return for the year involved; but it is measured, rather, with respect to "the expiration of the time prescribed by law for the assessment of a deficiency for the fifth taxable year of the five consecutive taxable years specified in subsection (a)."

The applicable Treasury regulations (Regs. 111, sec. 130-1 (c)) likewise give recognition to the fact that the period of limitation for determining an "actual deficiency as defined in section 271" may have expired before the provisions of section 130 became applicable. They therefore point out that assessment of increases in tax under section 130 may be made by two separate methods: One to be used in cases where "the taxable year is one in respect of which an assessment could be made without regard to section 130"; and the other to be used where the year is one (like the years 1944 and 1945 here involved) in respect of which an assessment for such year "would be prevented by any provision of law (e. g., the period of limitation upon the assessment of tax) * * *."

I would have held, on the basis of the foregoing (assuming that this Court does have jurisdiction to pass 1958 U.S. Tax Ct. LEXIS 256">*312 upon a claim for overpayment, based on an item wholly unrelated to the application of section 130), that any overpayment herein is barred by the statute of limitations provided in section 275; and that such statute of limitations was not extended by section 130 (c).

29 T.C. 878">*902 III. Re Estoppel.

The majority of the Court, in that portion of the above Opinion designated as Issue 3, rejected the plea of the Commissioner that petitioner's claim to overpayments should be denied by application of equitable estoppel. The reasoning of the majority is that the compromise settlement agreement which the parties executed in 1949, on Form 870-TS (Modified), was not a formal closing agreement within the meaning of section 3760 (which I agree is true); and that equitable estoppel should not be applied, because the respondent has not established that he suffered any "detriment." The majority said:

The detriment shown in this proceeding is merely the running of the statute of limitations with regard to possible additional deficiencies relating to the years 1944 and 1945. We are not informed as to what those deficiencies, if any, might have been. * * *

Several decisions of other courts are to the contrary. The 1958 U.S. Tax Ct. LEXIS 256">*313 case of Guggenheim v. United States, (Ct. Cl.) 77 F. Supp. 186">77 F. Supp. 186, certiorari denied 335 U.S. 908">335 U.S. 908, involved a situation almost identical to the present one. There the parties had executed a Form 870-TS settlement agreement, which contained covenants substantially the same as those contained in the agreement here involved; and, after the amounts of the taxes therein agreed upon had been paid and the statute of limitations had barred respondent from assessing any deficiency in respect of the settled issues, the taxpayer filed a claim for refund in violation of the agreement. The Court of Claims said, at page 196:

At the time the agreement in this case was executed the statute had not run on the collection of further deficiencies, but when the claims for refund were filed the statute had run. It would obviously be inequitable to allow the plaintiff to renounce the agreement when the Commissioner cannot be placed in the same position he was when the agreement was executed. A clear case for the application of the doctrine of equitable estoppel exists and should be applied. * * *

The Court of Claims, in said case, also gave consideration to Botany Worsted Mills v. United States, 278 U.S. 282">278 U.S. 282. 1958 U.S. Tax Ct. LEXIS 256">*314 In this case, the Supreme Court stated that formal closing agreements, such as those now provided for in section 3760 of the 1939 Code, provide the exclusive method for compromising tax controversies; but the Supreme Court further stated therein, that it was not determining whether an informal agreement "may when executed become, under some circumstances, binding on the parties by estoppel * * *."

Other cases in which estoppel was applied in situations similar to the present are Baldwin v. Higgins, not officially reported (S. D. N. Y., 1937; 19 A. F. T. R. 1341, 37-2U. S. T. C. par. 9434) affirmed on other grounds (C. A. 2) 100 F.2d 405; Schneider v. Kelm, (D. Minn.) 137 F. Supp. 871">137 F. Supp. 871, affirmed on other grounds (C. A. 8) 237 F.2d 721; Girard v. Gill, (N. D. N. C.) 142 F. Supp. 770">142 F. Supp. 770, affirmed per 29 T.C. 878">*903 curiam (C. A. 4) 234 F.2d 166; and Daugette v. Patterson, (C. A. 5) 250 F.2d 753, affirming (N. D. Ala.)    F. Supp.   .

In the Baldwin case, supra, the District Court said:

The waiver and consent agreement * * * is a binding contract and it was accepted and acted upon by the Commissioner. * * *

Furthermore, it would seem unconscionable and inequitable to permit the plaintiff to sustain a recovery 1958 U.S. Tax Ct. LEXIS 256">*315 based on his own broken promises. * * *

In the Schneider case, supra, it was said, at page 876:

If this would not create an estoppel, we would have the anomaly that taxpayers, if successful, would still retain the fruit of their broken bargain.

And in the recent Daugette case, supra, the Court of Appeals for the Fifth Circuit not only applied the doctrine of estoppel, but also reviewed and distinguished most of the cases which have been relied upon by the majority of this Court, in its above Opinion.

It now is well settled, that equitable estoppel or estoppel in pais is applied by courts of law, as well as in equity. Wehrman v. Conklin, 155 U.S. 314">155 U.S. 314, 155 U.S. 314">327; 19 Am. Jur. 831; 3 Pomeroy, Equity Jurisprudence, p. 181 (5th ed.). Also, the doctrine of equitable estoppel has been applied frequently by this Court, and by Courts of Appeals on the review of decisions of this Court. See for example: Aurore B. Benoit, 25 T.C. 656, 668-669, and Lucas v. Hunt, (C. A. 5) 45 F.2d 781. See also Fairmont Aluminum Co., 22 T.C. 1377, affirmed (C. A. 4) 222 F.2d 622, certiorari denied 350 U.S. 833">350 U.S. 833, in which the doctrine of collateral estoppel was discussed and applied.

By reason of all the foregoing, I 1958 U.S. Tax Ct. LEXIS 256">*316 respectfully dissent.
