Petitioner did not retain the envelope containing the notice of deficiency. There is no evidence in the record whether the envelope containing the notice of deficiency bore a postmark.

Based upon the actual date of mailing, the 90-day period prescribed in section 6213 (a) for filing a timely petition with the Court expired on Thursday, June 27, 1996, a day that was not a legal holiday in the District of Columbia.

The petition was hand-delivered to the Court on Friday, June 28, 1996. The petition is dated June 28, 1996, and is signed by petitioner's counsel, Eric W. Lundy. At the time the petition was filed, petitioner resided at West Friendship, Maryland.

As indicated, respondent filed a Motion to Dismiss for Lack of Jurisdiction asserting that the case should be dismissed on the ground that the petition was not timely filed under section 6213 (a). Petitioner filed an objection to respondent's motion arguing that, due to the erroneous date of mailing on the notice of deficiency, the1997 Tax Ct. Memo LEXIS 12">*16 90-day period prescribed in section 6213 (a) for filing a petition with the Court should be computed from Saturday, March 30, 1996, the date that petitioner actually received the notice of deficiency.

This case was called for hearing in Washington, D.C., at the Court's motions session. Counsel for both parties appeared at the hearing and presented argument on the pending motion.

Discussion

The Tax Court is a court of limited jurisdiction, and we may exercise our jurisdiction only to the extent authorized by Congress. Naftel v. Commissioner, 85 T.C. 527">85 T.C. 527, 85 T.C. 527">529 (1985). The Court's jurisdiction to redetermine a deficiency depends upon the issuance of a valid notice of deficiency and a timely filed petition. Rule 13 (a), (c); Monge v. Commissioner, 93 T.C. 22">93 T.C. 22, 93 T.C. 22">27 (1989); Normac, Inc. v. Commissioner, 90 T.C. 142">90 T.C. 142, 90 T.C. 142">147 (1988). Section 6212 (a) expressly authorizes the Commissioner, after determining a deficiency, to send a notice of deficiency to the taxpayer by certified or registered mail. It is sufficient for jurisdictional purposes if the Commissioner mails the notice of deficiency to1997 Tax Ct. Memo LEXIS 12">*17 the taxpayer's "last known address." Sec. 6212 (b); Frieling v. Commissioner, 81 T.C. 42">81 T.C. 42, 81 T.C. 42">52 (1983). If a notice of deficiency is mailed to the taxpayer's last known address, actual receipt of the notice is immaterial. King v. Commissioner, 857 F.2d 676">857 F.2d 676, 857 F.2d 676">679 (9th Cir. 1988), affg. 88 T.C. 1042">88 T.C. 1042 (1987); Yusko v. Commissioner, 89 T.C. 806">89 T.C. 806, 89 T.C. 806">810 (1987); 81 T.C. 42">Frieling v. Commissioner, supra at 52. The taxpayer, in turn, has 90 days from the date the notice of deficiency is mailed (150 days if the notice is mailed to a taxpayer outside of the United States) to file a petition in this Court for a redetermination of the deficiency. Sec. 6213 (a); Estate of Moffat v. Commissioner, 46 T.C. 499">46 T.C. 499, 46 T.C. 499">501 (1966).

There is no dispute that respondent mailed the notice of deficiency to petitioner on March 29, 1996. If the 90-day period for filing a petition with the Court is computed from the date that respondent actually placed the notice of deficiency in the mail, we would be compelled to dismiss this case for lack of jurisdiction1997 Tax Ct. Memo LEXIS 12">*18 on the ground that the petition was hand-delivered to the Court and filed 91 days after this date. The question to be resolved in this case, however, is whether the erroneous date appearing on the notice of deficiency (March 29, 1997, rather than March 29, 1996) provides a basis for computing the 90-day period from March 30, 1996 -- the date that petitioner actually received the notice of deficiency.

Section 6213 (a) provides in pertinent part:

(a) Time For Filing Petition and Restriction On Assessment. -- Within 90 days, or 150 days if the notice is addressed to a person outside the United States, after the notice of deficiency authorized in section 6212 is mailed * * *, the taxpayer may file a petition with the Tax Court for a redetermination of the deficiency. * * *

In extraordinary circumstances, we have recognized exceptions to the general rule that the date of mailing is the date that the Commissioner actually places the notice of deficiency in the mail. One of the more comprehensive discussions of the subject is set forth in our original opinion in 61 T.C. 97">Traxler v. Commissioner, supra.

In Traxler, the taxpayers received a notice of deficiency dated March 29, 1973, in an envelope that was date stamped March 31, 1973. The taxpayers mailed their petition to the Court 91 days after the date appearing on the notice of deficiency but 89 days after the date stamp appearing on the envelope bearing the notice of deficiency. The Commissioner moved1997 Tax Ct. Memo LEXIS 12">*20 to dismiss the petition for lack of jurisdiction on the ground that it was not timely filed. The taxpayers objected to the Commissioner's motion asserting that the date of mailing for purposes of section 6213 (a) should be the date stamped on the envelope in which the notice of deficiency was mailed.

In attempting to define the term "is mailed" appearing in section 6213 (a), we first observed that:

The term itself is not precise, and the legislative history shows only that such date is not the date of actual receipt by the taxpayer. See Seidman's Legislative History of Federal Income Tax Laws (1938-1861) p.759; United Telephone Co., 1 B.T.A. 450">1 B.T.A. 450 (1925). [Traxler v. Commissioner, 61 T.C. 97">61 T.C. 98-99.]

In the absence of a statutory definition of the term "is mailed", we focused on three dates that arguably could apply for purposes of computing the 90-day filing period: (1) The date appearing on the notice of deficiency; (2) the date that the Commissioner delivered the notice of deficiency to the U.S.1997 Tax Ct. Memo LEXIS 12">*21 Postal Service; and (3) the date of the postmark (if any) appearing on the envelope bearing the notice of deficiency. Traxler v. Commissioner, 61 T.C. 97">61 T.C. 99. Consistent with cases such as 4 B.T.A. 223">Southern California Loan Association v. Commissioner, supra, and 1 B.T.A. 26">Hurst, Anthony & Watkins v. Commissioner, supra, we immediately eliminated from consideration the date appearing on the notice of deficiency. We reasoned that "it seems best not to make taxpayers dependent on the efficiency of the Internal Revenue Service [in dating the notice of deficiency]". Traxler v. Commissioner, 61 T.C. 97">61 T.C. 99.

Turning our attention to the two remaining possibilities, the date of actual mailing and the date stamped on the envelope bearing the notice of deficiency, we observed:

Certainly in everyday parlance a postmark date is regarded as the date of mailing. Normally if one is asked when a letter "is mailed," he will look to the postmark. That is obviously what the petitioners did in this case. They saw the date "Mar. 31, 1973" on the envelope. The best evidence of the postmark date is1997 Tax Ct. Memo LEXIS 12">*22 the postmark itself. Without it, the next best evidence is the Commissioner's receipt for certified mail. This will not place any additional burden on the Internal Revenue Service. If its receipt for certified mail shows that more than 90 days has passed, the normal challenge to jurisdiction will be forthcoming. Only in cases where the postmark carries a later date can the petitioner successfully resist. In no case will the Commissioner's certified mail procedure need to be changed. [61 T.C. 97">Id. at 100.]

1997 Tax Ct. Memo LEXIS 12">*23 Notwithstanding the statement in 61 T.C. 97">Traxler v. Commissioner, supra, to the contrary, we also have had occasion to hold that the date appearing on the notice of deficiency is the date of mailing for purposes of section 6213 (a). In particular, in both Loyd v. Commissioner, T.C. Memo. 1984-172, and Jones v. Commissioner, T.C. Memo. 1984-171, the Commissioner placed the notices of deficiency in the mail 3 days prior to the date appearing on the notices of deficiency. The petitions were mailed to the Court within 90 days of the date appearing on the notices of deficiency but more than 90 days after the date that the notices were actually mailed.

In denying the Commissioner's motions to dismiss for lack of jurisdiction in Loyd v. Commissioner, supra, and Jones v. Commissioner, supra, we concluded that the taxpayers (or their counsel) had reasonably relied upon the erroneous date appearing on the notices of deficiency as the date of mailing. Consequently, to avoid frustrating the statutory provisions designed to afford taxpayers an opportunity for prepayment review1997 Tax Ct. Memo LEXIS 12">*24 of the Commissioner's deficiency determinations, we decided to treat the notices of deficiency as if they were mailed on the date appearing on the notices. ⁴

We conclude our survey of the case law in this area with a brief mention of the line of cases involving undated notices of deficiency. See Hurst, Anthony & Watkins v. Commissioner, 1 B.T.A. 26">1 B.T.A. 26 (1924); and Casqueira v. Commissioner, T.C. Memo. 1981-428. We have uniformly analyzed these cases by applying the normal rule that the date of mailing is the date that the notice of deficiency is actually placed in the mail. Cf. Donoghue v. Commissioner, T.C. Memo. 1977-276 (90-day period computed 1997 Tax Ct. Memo LEXIS 12">*25 from actual date of mailing where notice of deficiency was actually mailed March 18, 1976, but erroneously dated March 18, 1975).

Respondent contends that the date that the notice of deficiency was actually mailed in this case is controlling for purposes of computing the 90-day period for filing a petition with the Court, and that it was unreasonable for petitioner to rely on any other date in filing his petition. Relying on cases such as Loyd v. Commissioner, supra, and Jones v. Commissioner, supra, petitioner counters that it has been the Court's practice to permit a taxpayer to use the best date available under the circumstances in computing the 90-day period for filing a petition with the Court. Because the notice of deficiency that he received was incorrectly dated, petitioner contends that he should be permitted to rely on the date that he actually received the notice of deficiency (as the best date available to him) in computing the 90-day period for filing a petition with the Court.

Our survey of the case law in this area shows that the best evidence of the date of mailing of a notice of deficiency is the postmark, 1997 Tax Ct. Memo LEXIS 12">*26 if there is one, on the envelope bearing the notice of deficiency. See Traxler v. Commissioner, 61 T.C. 97">61 T.C. 99, modified 63 T.C. 534">63 T.C. 534 (1975). In the absence of such a postmark, the date of mailing of a notice of deficiency is the date that the Commissioner places the notice of deficiency in the mail, although an exception may be made where the taxpayer has been misled or has reasonably relied to his detriment upon some later date appearing on the deficiency notice itself. Petitioner does not contend that he was misled or that he reasonably relied upon another date of mailing. To the contrary, petitioner asserts that, because of uncertainty as to the correct date of mailing, he was entitled to treat the date that he received the notice of deficiency as the date of mailing. Unfortunately for petitioner, we have previously rejected the proposition that the date of mailing contemplated in section 6213 (a) can be equated with the date that a taxpayer actually receives a notice of deficiency. See Traxler v. Commissioner, 61 T.C. 97">61 T.C. 98-99. We see no reason to abandon that position under the circumstances1997 Tax Ct. Memo LEXIS 12">*27 presented. ⁵

1997 Tax Ct. Memo LEXIS 12">*28 The notice of deficiency was delivered by the U.S. Postal Service to petitioner on Saturday, March 30, 1996. Given that the date of delivery is known, it follows that the notice of deficiency must have been mailed at least one day prior to its delivery to, and receipt by, petitioner. When petitioner received the notice of deficiency on March 30, 1996 (delivered by the U.S. Postal Service) it would have been unreasonable for him to assume a mailing date later than March 29, 1996, the date prior to delivery. In fact, March 29, 1996, was the actual date of mailing, and petitioner has failed to allege or show that the envelope containing the notice was not postmarked on that date. The date on the face of the notice, being a full year later than the date of mailing, was so patently the result of clerical error that petitioner makes no claim of detrimental reliance. The fact that petitioner's counsel, Eric W. Lundy, did not sign and hand-deliver the petition to the Court until Friday June 28, 1996, 91 days after the mailing of the notice of deficiency, was not attributable to the erroneous date on the notice as in Loyd v. Commissioner, supra, or Jones v. Commissioner, supra.1997 Tax Ct. Memo LEXIS 12">*29

Accordingly, based on the particular circumstances of this case, we conclude that the 90-day period for filing a petition with the Court is computed from the actual mailing date of March 29, 1996. Because the petition was not filed within 90 days of that date, we will grant respondent's motion to dismiss for lack of jurisdiction. ⁶

To reflect the foregoing,

An order will be entered granting respondent's Motion to Dismiss for Lack of Jurisdiction.
