89 T.C. 1063">*1063 This case is before the Court on the parties' cross-motions to dismiss for lack of jurisdiction. Respondent contends that we lack jurisdiction because petitioner failed to file a petition with this Court within the time prescribed by section 6213(a). ¹ Petitioner seeks to have this case dismissed on the ground that the statutory notice of deficiency was not mailed, or if mailed, 1987 U.S. Tax Ct. LEXIS 181">*182 that it was not sent to him at his "last known address," as that term is used in section 6212(b)(1).

Argument on both motions was heard at a trial session of the Court at Los Angeles, California. The record consists of a stipulation of facts, testimony, and exhibits received at 89 T.C. 1063">*1064 the hearing. The stipulation of facts and exhibits attached thereto are incorporated herein by this reference. The parties have also submitted memoranda of law in support of their positions.

FINDINGS OF FACT

At the time of filing his petition herein, Gregory W. McKay (petitioner) was a resident of Beverly Hills, California. Petitioner timely filed individual Federal income tax returns for 1972 and 1973 with the Internal Revenue Service Center at Fresno, California (the Fresno Service Center). On his 1972 tax return, petitioner's address was shown as 360 North Camden Drive, Beverly Hills, California 90210. 1987 U.S. Tax Ct. LEXIS 181">*183 Petitioner's address as reflected on his 1973 tax return was 9665 Wilshire Boulevard, Beverly Hills, California 90212 (the Wilshire Boulevard address). As of April 20, 1975, however, petitioner was no longer a tenant at the Wilshire Boulevard address. ²

For the years 1974 and 1976, petitioner's returns were timely filed with the Fresno Service Center. ³ Petitioner's tax returns for these years bear a mailing address of P.O. Box 1081, Beverly Hills, California 90213 (P.O. Box 1081).

On September 26, 1975, petitioner filed Forms 843 (Claim), for taxable years 1972 and 1973 with the Fresno Service Center. Petitioner's mailing address was shown as P.O. Box 1081 on both refund claim forms.

1987 U.S. Tax Ct. LEXIS 181">*184 On that same date, petitioner also filed a power of attorney (Form 2848) with the Fresno Service Center. This document, which was executed by petitioner, appointed Herbert D. Sturman as petitioner's attorney-in-fact in connection with "any and all federal tax matters pertaining to calendar years 1971-1974, including, but not limited to, the filing and processing of Internal Revenue Forms 843 for the calendar years 1971-1973." The Form 2848 directed that copies of notices and other written communications addressed to petitioner should be sent to Mr. Sturman. 89 T.C. 1063">*1065 Petitioner's address was listed on Form 2848 as P.O. Box 1081.

On October 7, 1975, and February 27, 1976, respondent wrote to petitioner with respect to his claims for refund. Both of these letters were addressed to petitioner at P.O. Box 1081. The second letter advised petitioner that his refund claims would be suspended, pending completion of the criminal investigation of his tax liabilities for the years in issue.

On April 7, 1977, respondent sent a copy of the statutory notice of deficiency for 1972 and 1973 to Mr. Sturman by ordinary mail. This copy of the statutory notice of deficiency set forth petitioner's1987 U.S. Tax Ct. LEXIS 181">*185 mailing address as 9665 Wilshire Boulevard.

Mr. Sturman received the copy of petitioner's notice of deficiency within several days of mailing, but prior to April 13, 1977. It was Mr. Sturman's normal business practice to deliver copies of Government documents served upon him to his clients within 3 or 4 days of receipt of such documents. Specifically, with respect to notices of deficiency, Mr. Sturman's normal business practice was to promptly meet with the client and hand-deliver the copy to that client. In this case, Mr. Sturman followed his normal business procedures and physically handed petitioner the copy of the notice of deficiency within several days of receiving such document.

Subsequently, on April 28, 1977, the Department of Justice filed with the U.S. District Court for the Central District of California a notice of mandatory stay of proceedings pursuant to Internal Revenue Code section 7422(e), wherein the District Court was notified that the Internal Revenue Service had issued a statutory notice of deficiency to petitioner on April 7, 1977. Mr. Sturman also received this notice with the attached copy of the notice of deficiency and in accordance with his business1987 U.S. Tax Ct. LEXIS 181">*186 practice, delivered it to petitioner.

The deficiencies and section 6653(b) additions to tax for 1972 and 1973 were assessed by respondent on September 12, 1977. The notices thereof were mailed to petitioner at 89 T.C. 1063">*1066 his P.O. Box 1081 address. ⁴

Respondent no longer has a copy of Form 3877, Application for Registration or Certification (certified mailing list) which would show mailing of the notice dated April 7, 1977. These records are routinely destroyed after 5 years. Moreover, because respondent1987 U.S. Tax Ct. LEXIS 181">*187 no longer has the administrative file, there is no record of whether the original notice of deficiency or duplicate originals were ever returned to respondent by the Postal Service.

Petitioner filed his petition with the Court on November 4, 1985, more than 8 years beyond the 90-day period set forth in section 6213.

OPINION

The parties have each moved this Court to dismiss for lack of jurisdiction, but on different grounds. Petitioner argues that the statutory notice of deficiency, if in fact mailed, was not sent to his last known address, as required by section 6212(b), and is therefore not valid. Petitioner, relying on Mulvania v. Commissioner, 769 F.2d 1376">769 F.2d 1376 (9th Cir. 1985) (Mulvania II), affg. a Memorandum Opinion of this Court, claims that only an original notice of deficiency sent directly to a taxpayer constitutes a valid notice of deficiency. Respondent contends that this Court lacks jurisdiction because the petition was filed more than 90 days after the notice of deficiency was mailed. It is respondent's position that petitioner actually, physically received a copy of the notice of deficiency within sufficient time to timely petition 1987 U.S. Tax Ct. LEXIS 181">*188 this Court. Respondent asserts that as a result of petitioner's long delay in petitioning the Tax Court, he has been prejudiced. Accordingly, respondent alternatively argues that the Court should apply the doctrines of estoppel and laches to preclude petitioner from arguing that the notice of deficiency was not sent to his last known address.

89 T.C. 1063">*1067 It is well settled that to maintain an action in this Court, there must be a valid notice of deficiency and a timely petition. See Pyo v. Commissioner, 83 T.C. 626">83 T.C. 626, 83 T.C. 626">632 (1984); Mollet v. Commissioner, 82 T.C. 618">82 T.C. 618, 82 T.C. 618">623 (1984), affd. without published opinion 757 F.2d 286">757 F.2d 286 (11th Cir. 1985); Keeton v. Commissioner, 74 T.C. 377">74 T.C. 377, 74 T.C. 377">379 (1980). Regardless of whether petitioner or respondent prevails, it is clear that we lack jurisdiction to entertain this case on its merits. We therefore must decide on what ground. See Shelton v. Commissioner, 63 T.C. 193">63 T.C. 193 (1974); O'Brien v. Commissioner, 62 T.C. 543">62 T.C. 543, 62 T.C. 543">548 (1974).

On the facts in this case, we agree with respondent1987 U.S. Tax Ct. LEXIS 181">*189 that the notice of deficiency is valid because petitioner received actual notice of the deficiencies determined against him without prejudicial delay. The fact that petitioner received a copy of the notice instead of the original is irrelevant. Because of this conclusion, we find it unnecessary to decide whether the notice of deficiency was sent to petitioner's last known address or to consider respondent's alternative arguments.

Section 6212(a) provides that, if the Commissioner determines a deficiency in income tax, "he is authorized to send notice of such deficiency to the taxpayer by certified mail or registered mail." Such notice of deficiency "shall be sufficient" if mailed to the taxpayer at his last known address, unless the Commissioner has been properly notified that a fiduciary has been substituted for the taxpayer. Sec. 6212(b)(1). If the notice is mailed to a taxpayer in the United States, he has 90 days after the mailing of the notice to file his petition for redetermination of the deficiency with the Tax Court. Sec. 6213(a). These provisions were designed to afford a taxpayer notice of the Commissioner's determination and an opportunity to litigate the validity1987 U.S. Tax Ct. LEXIS 181">*190 of such determination in this Court without first paying the deficiency. Mulvania v. Commissioner, 81 T.C. 65">81 T.C. 65 (1983) (Mulvania I), and cases cited therein. Thus, the notice constitutes the taxpayer's ticket to the Tax Court, and without it, there could be no prepayment judicial review of the deficiency.

A properly mailed notice of deficiency is valid irrespective of whether such notice is in fact received by the taxpayer. 89 T.C. 1063">*1068 United States v. Zolla, 724 F.2d 808">724 F.2d 808, 724 F.2d 808">810 (9th Cir. 1984), cert. denied 469 U.S. 830">469 U.S. 830 (1984); ⁵Lifter v. Commissioner, 59 T.C. 818">59 T.C. 818 (1973). As we emphasized in our opinion in Mulvania I, the language of section 6212(b)(1) is clearly permissive, for Congress did not create a mandatory address to which a notice of deficiency must be mailed, but rather provided the Commissioner a "safe harbor" address to which he could send the notice.⁶81 T.C. 65">81 T.C. 67-68. DeWelles v. United States, 378 F.2d 37">378 F.2d 37, 378 F.2d 37">39 (9th Cir. 1967); Alta Sierra Vista, Inc. v. Commissioner, 62 T.C. 367">62 T.C. 367, 62 T.C. 367">374 (1974),1987 U.S. Tax Ct. LEXIS 181">*191 affd. without published opinion 538 F.2d 334">538 F.2d 334 (9th Cir. 1976); Zenco Engineering Corp. v. Commissioner, 75 T.C. 318">75 T.C. 318, 75 T.C. 318">321-322 (1980), affd. without published opinion 673 F.2d 1332">673 F.2d 1332 (7th Cir. 1981) deficiency notices held to be effective even though taxpayer did not actually receive such notice).

1987 U.S. Tax Ct. LEXIS 181">*192 Conversely, if a notice of deficiency is improperly addressed yet the taxpayer receives it without prejudicial delay, his complaint that it was not mailed to him at his last known address is unavailing. Clodfelter v. Commissioner, 527 F.2d 754">527 F.2d 754, 527 F.2d 754">757 (9th Cir. 1975), affg. 57 T.C. 102">57 T.C. 102 (1971); Goodman v. Commissioner, 71 T.C. 974">71 T.C. 974 (1979); Zaun v. Commissioner, 62 T.C. 278">62 T.C. 278 (1974). Providing the taxpayer with actual notice of deficiency in a timely manner is the essence of the statutory scheme. 81 T.C. 65">Mulvania I, supra at 68, and cases cited therein. Thus, the receipt of the communication gives the taxpayer actual notice of the IRS's intention to assess a deficiency.

We have previously rejected the argument that when a petition is not timely filed, the error in an address is prejudicial as a matter of law and that the notice of deficiency is invalid. Looper v. Commissioner, 73 T.C. 690">73 T.C. 690 (1980). Whether a taxpayer has been prejudiced by an improperly addressed notice is a question of fact. The taxpayer's failure to file a timely petition1987 U.S. Tax Ct. LEXIS 181">*193 is a relevant 89 T.C. 1063">*1069 factor in the inquiry, but alone is not decisive. 73 T.C. 690">Looper v. Commissioner, supra at 698-699.

Moreover, section 6212(a) merely authorizes the Secretary to send notices of deficiency by registered or certified mail. Other means of delivery may be used. ⁷ The "purpose of the statutory requirement for the issuance of deficiency notices is to inform the taxpayer that the Commissioner means to assess additional taxes against him, and to provide time for the taxpayer to petition this Court for a redetermination if he is so advised." Perlmutter v. Commissioner, 44 T.C. 382">44 T.C. 382, 44 T.C. 382">400 (1965), affd. 373 F.2d 45">373 F.2d 45 (10th Cir. 1967).

1987 U.S. Tax Ct. LEXIS 181">*194 On the facts of this record, we find that petitioner received actual notice of the deficiencies in question without prejudicial delay. Our conclusion is based on the uncontradicted testimony of petitioner's former attorney, Mr. Sturman, who was a credible and forthright witness. Although petitioner alleged in his petition and memorandum of law that he never received a notice of deficiency for the years in issue, petitioner did not testify at the hearing on this matter. Because petitioner did not testify to a fact peculiarly within his knowledge, we conclude that such testimony would be unfavorable to him. See Wichita Terminal Elevator Co. v. Commissioner, 6 T.C. 1158">6 T.C. 1158 (1946), affd. 162 F.2d 513">162 F.2d 513 (10th Cir. 1947).

We find that the purpose of section 6212 -- the communication to a taxpayer that respondent has determined a deficiency -- was achieved in this case. See, e.g., Berger v. Commissioner, 404 F.2d 668">404 F.2d 668 (3d Cir. 1968), affg. 48 T.C. 848">48 T.C. 848 (1967); 62 T.C. 367">Alta Sierra Vista, Inc. v. Commissioner, supra;62 T.C. 278">Zaun v. Commissioner, supra;1987 U.S. Tax Ct. LEXIS 181">*195 59 T.C. 818">Lifter v. Commissioner, supra.Our conclusion in no way implies that a power of attorney which authorizes that copies be sent to a taxpayer's authorized representative effectively makes that address a taxpayer's last known address. Rather, when a taxpayer receives a copy of the statutory notice without prejudicial delay he 89 T.C. 1063">*1070 has actual knowledge of a notice of deficiency. See Stamm International Corp. v. Commissioner, 84 T.C. 248">84 T.C. 248 (1985); 71 T.C. 974">Goodman v. Commissioner, supra (where the taxpayer received a copy of the notice of deficiency from his/her attorney and timely filed a petition, the notice of deficiency was valid). ⁸ Upon its receipt, petitioner herein was informed. The copy of the notice which bore a date of April 7, 1977, required petitioner to make immediate inquiry as to when and how he should proceed, if he contemplated Tax Court review. Under these circumstances, a contrary determination that the notice was insufficient "would allow the technical an undue triumph over the substantial." Commissioner v. Stewart, 186 F.2d 239">186 F.2d 239, 186 F.2d 239">242 (6th Cir. 1951),1987 U.S. Tax Ct. LEXIS 181">*196 and cases cited therein. Thus, we conclude that petitioner here received his "ticket" to the Tax Court and ample opportunity to file a petition for review. Delman v. Commissioner, 384 F.2d 929">384 F.2d at 934.

At the time petitioner received actual notice of the deficiencies determined against him he became responsible for filing a timely petition with this Court. There is no explanation for the failure to file such petition, but it is apparent that inaction, after receipt of the notice, was responsible for the late filing. Therefore, petitioner's failure to file a timely petition cannot be said to have been the direct result of any error in the address to which the notice of deficiency was mailed. 63 T.C. 193">Shelton v. Commissioner, supra;Zikria v. Williams, 535 F. Supp. 481">535 F. Supp. 481 (W.D. Pa. 1982).1987 U.S. Tax Ct. LEXIS 181">*197

Moreover, we find that the facts of this case are distinguishable from those of Mulvania v. Commissioner, T.C. Memo. 1984-98, affd. 769 F.2d 1376">769 F.2d 1376 (9th Cir. 1985). In Mulvania II, the taxpayer did not receive either the original or the copy of the notice of deficiency; rather, he was informed by his accountant pursuant to a telephone conversation that a copy of the notice had been sent to the accountant's office. ⁹ This conversation occurred a month 89 T.C. 1063">*1071 and a half after the statute of limitations had expired. Unlike the situation in Mulvania II, petitioner here received actual written notice of the deficiencies determined against him, and second, we have determined that he received such notice without prejudicial delay. ¹⁰ Where the notice is sent to the wrong address and never delivered or delivered with prejudicial delay, the statutory purpose is not served and it would be manifestly unfair to deny the taxpayer his prepayment hearing; but that is not the case here. 535 F. Supp. 481">Zikria v. Williams, supra; Goolsby v. Tomlinson, 246 F. Supp. 674">246 F. Supp. 674 (S.D. Fla. 1965).1987 U.S. Tax Ct. LEXIS 181">*198

1987 U.S. Tax Ct. LEXIS 181">*199 We hold that the notice of deficiency herein is valid. Accordingly, we will deny petitioner's motion to dismiss and grant respondent's motion to dismiss since the petition was not timely filed.

An appropriate order will be issued.
