CHIECHI, Judge: Respondent determined a deficiency of $3,995.55 in petitioner's Federal income tax for his taxable year 2007.

The issue remaining for decision is whether petitioner is entitled to deduct $9,854 of the "Other expenses" totaling $12,294 ¹ that he claimed in Schedule C, Profit or Loss From Business, which he included with the Federal income tax return that he filed for his taxable year 2007. We hold that he is not.

Some of the facts have been stipulated and are so found.

At the time petitioner filed the petition in this case, he resided in New York, New York.

During 2007, Convera Technologies (Convera), whose office was in Vienna, Virginia, employed petitioner full time as a regional sales director for which he received from that company wages of $170,439. As a regional sales director of Convera, petitioner supervised certain other sales personnel that that company 2012 Tax Ct. Memo LEXIS 50">*51 employed.

During 2007, petitioner, who was not a professional speaker, was the sole owner of THJ & Associates, LLC (THJ). During that year, THJ had an employer identification number that the Internal Revenue Service had assigned to it at a time not established by the record.

Petitioner timely filed Form 1040, U.S. Individual Income Tax Return, for his taxable year 2007 (2007 return). In that return, petitioner reported wages of $170,440, ^{22012 Tax Ct. Memo LEXIS 50">*52} taxable interest of $8,016, ordinary dividends of $7,991, a business loss of $14,027 from Schedule C, Profit or Loss From Business (2007 Schedule C), a capital loss of $396 from Schedule D, Capital Gains and Losses, and total income of $172,024.

In the 2007 Schedule C that petitioner included with his 2007 return, petitioner showed (1) himself as the "Proprietor", (2) "Marketing" as the "Principal business or profession", (3) "THJ & Associates, LLC" as the "Business name", and (4) an address in New York, New York, that was different from the address that petitioner showed as his "Home address" in his 2007 return. ³ In the 2007 Schedule C, petitioner showed no income and claimed total expenses and a net loss of $14,027. The total expenses claimed in the 2007 Schedule C included claimed "Other expenses" of $12,294. ^{42012 Tax Ct. Memo LEXIS 50">*53} Those "Other expenses" consisted of the following expenses that petitioner claimed for: (1) "Training costs" of $10,182, (2) "Telephone and internet" of $539, and (3) "Dues and Subscriptions" of $1,573.

Of the total "Training costs" of $10,182, $7,742 related to online course materials and online coaching materials, and the remaining $2,440 related to travel, meals, and lodging. Of the total "Telephone and internet" expenses of $539, $48.20, $50.20, and $133.73 were for expenses charged by "Domain names/Hosting", "Domains/Hosting SRVC", and "Domains/Hosting", respectively, and the remaining $306 was for expenses charged for petitioner's Time Warner Cable service. ^{52012 Tax Ct. Memo LEXIS 50">*54} Of the total "Dues and Subscriptions" of $1,573, $335, $140, $53, $633, $44, and $215 were for expenses charged for mailbox rentals, Word Champion Edge "web and spkrs", Franklin Covey, periodicals, credit reports, and software, respectively. ⁶

Respondent issued to petitioner a notice of deficiency (notice) for his taxable year 2007. In that notice, respondent disallowed the "Other expenses" of $12,294 that petitioner claimed in his 2007 Schedule C.

Petitioner bears the burden of proving that the determinations in the notice are erroneous. ⁷SeeRule 142(a); Welch v. Helvering, 290 U.S. 111">290 U.S. 111, 290 U.S. 111">115, 54 S. Ct. 8">54 S. Ct. 8, 78 L. Ed. 212">78 L. Ed. 212, 1933-2 C.B. 112 (1933). Moreover, deductions are a matter of legislative grace, and petitioner bears the burden of proving entitlement to any deduction claimed. See INDOPCO, Inc. v. Commissioner, 503 U.S. 79">503 U.S. 79, 503 U.S. 79">84, 112 S. Ct. 1039">112 S. Ct. 1039, 117 L. Ed. 2d 226">117 L. Ed. 2d 226 (1992). Petitioner was required to maintain records sufficient to establish the amount of any deduction claimed. Seesec. 6001; sec. 1.6001-1(a), Income Tax Regs.

It is petitioner's 2012 Tax Ct. Memo LEXIS 50">*55 position that he is entitled to deduct under section 162(a) all of the "Other expenses" that he claimed in his 2007 Schedule C, except the expenses relating to travel, meals, and lodging that he claimed as part of those "Other expenses". ⁸ It is respondent's position that petitioner is not entitled to deduct any of those "Other expenses".

A taxpayer is entitled to deduct all the ordinary and necessary expenses paid or incurred during the taxable year in carrying on a trade or business. ⁹Sec. 162(a). In order for an activity of a taxpayer to constitute the carrying on by the taxpayer of a trade or business within the meaning of section 162(a), the taxpayer's primary purpose for carrying on the activity must be for income or profit. Commissioner v. Groetzinger, 480 U.S. 23">480 U.S. 23, 480 U.S. 23">35, 107 S. Ct. 980">107 S. Ct. 980, 94 L. Ed. 2d 25">94 L. Ed. 2d 25 (1987). Moreover, the taxpayer must be involved in the activity with continuity and regularity. A sporadic activity will not qualify as carrying on a trade or business for purposes of section 162(a). Id. In addition, the trade or business requirement of section 162(a) is not met until the trade or business has begun to function as a going concern and the activities for which it was organized are 2012 Tax Ct. Memo LEXIS 50">*56 performed. ^{102012 Tax Ct. Memo LEXIS 50">*57} Jackson v. Commissioner, 86 T.C. 492">86 T.C. 492, 86 T.C. 492">514 (1986), aff'd, 864 F.2d 1521">864 F.2d 1521 (10th Cir. 1989).

Petitioner relies principally on his own testimony and certain documents that the parties stipulated (petitioner's documents) to establish his position that the "Other expenses" that he claimed in his 2007 Schedule C and that remain at issue satisfy all of the requirements of section 162(a) and therefore are deductible under that section. With respect to petitioner's 2012 Tax Ct. Memo LEXIS 50">*58 testimony, we found it to be uncorroborated, self-serving, vague, general, and/or conclusory in certain material respects. We shall not rely on petitioner's testimony to establish his position that all of the "Other expenses" claimed in his 2007 Schedule C that remain at issue satisfy all of the requirements of section 162(a). With respect to petitioner's documents, we did not find that those documents established petitioner's position with respect to the expenses at issue to which they pertain.

On the record before us, we find that petitioner has failed to carry his burden of showing for his taxable year 2007 that the primary purpose for any activities that he may have undertaken with respect to his claimed THJ marketing business was for income or profit, that he was involved in his claimed THJ marketing business with continuity and regularity, and that his claimed THJ marketing business was a going concern. On that record, we further find that petitioner has failed to carry his burden of showing that during the year at issue he was carrying on a marketing business through THJ within the meaning of section 162(a). ^{112012 Tax Ct. Memo LEXIS 50">*59}

Based upon our examination of the entire record before us, we find that petitioner has failed to carry his burden of establishing that he is entitled to deduct for his taxable year 2007 the "Other expenses" that he claimed in his 2007 Schedule C and that remain at issue.

We have considered all of the parties' contentions and arguments that are not discussed herein, and we find them to be without merit, irrelevant, and/or moot.

To reflect the foregoing,

Decision will be entered for respondent.
