MEMORANDUM OPINION

ARMEN, SPECIAL TRIAL JUDGE: This matter is before the Court on respondent's Motion to Dismiss for Lack of Jurisdiction, filed May 30, 2000. As discussed in detail below, we shall grant respondent's motion to dismiss. ¹

BACKGROUND

On January 6, 2000, respondent mailed a notice of deficiency to Donna J. Hendley (petitioner) determining a deficiency of $ 49,053 in her Federal income tax for 1995. There is no dispute that respondent mailed the notice to petitioner at her last known address.

On April 7, 2000, the Court received and filed a petition submitted on petitioner's behalf by her counsel, Jeffrey G. Williams (Mr. Williams). The petition2000 Tax Ct. Memo LEXIS 416">*417 is dated April 5, 2000.

The petition arrived at the Court in an envelope bearing sufficient postage, a priority mail sticker, and multiple U.S. Postal Service postmarks all dated April 6, 2000. The legend around the perimeter of the postmarks states: "USPS MESA AZ. STA. NO. 10". At the time that the petition was filed, petitioner resided in Flagstaff, Arizona.

Respondent filed a Motion to Dismiss for Lack of Jurisdiction on the ground that the petition was not filed within the 90-day period prescribed in section 6213(a). Petitioner filed an objection to respondent's motion to dismiss, accompanied by an affidavit executed by Mr. Williams, asserting that the petition was timely mailed to the Court on April 5, 2000. Mr. Williams' affidavit states in pertinent part that on April 5, 2000, at approximately 4:30 p.m., he delivered the petition to a so-called contract postal unit maintained at a small retail store known as Impressive Greetings, located at 1225 South Alma School Road, Mesa, Arizona. Mr. Williams further states that, at the time he mailed the petition, he saw the clerk affix a postmark on the envelope.

This matter was called for hearing at the Court's motions session in Washington, 2000 Tax Ct. Memo LEXIS 416">*418 D.C. Counsel for respondent appeared at the hearing and offered argument in support of respondent's motion to dismiss. Although no appearance was entered by or on behalf of petitioner at the hearing, petitioner did file a written statement with the Court pursuant to Rule 50(c). Following the hearing, the Court directed the parties to file responses providing additional details regarding the postal services provided at Impressive Greetings.

Both parties filed responses as directed by the Court. Respondent's response was accompanied by a declaration executed by Michael J. Noggle (Mr. Noggle), identified as a co-owner of Impressive Greetings. Mr. Noggle's declaration states that the services provided by Impressive Greetings as a contract postal unit are the equivalent of services provided by the U.S. Postal Service. The declaration further states that the contract postal unit at Impressive Greetings processes regular, priority, and express mail, as well as registered and certified mail. With regard to the practices and procedures employed by the contract postal unit at Impressive Greetings, the declaration states:

     5. The main post office branch in Mesa, Arizona picks2000 Tax Ct. Memo LEXIS 416">*419 up

   mail from our contract postal unit twice a day. Once at 2:15

   p.m., and again at 4:30 p.m. The 4:30 p.m. pick-up is the last

   mail pick-up of the day. There is a visible sign on the wall in

   the back of the contract postal unit telling customers that the

   pick-up times are at 2:15 p.m. and 4:30 p.m.

     6. Impressive Greetings is open for business until 5:00

   p.m. Monday through Friday.

               * * * * * * *

     8. Our policy is to turn our hand-stamp postmark date to

   the next day at 4:30 p.m. This way, any mail that goes out with

   the 4:30 p.m. mail has the current day's postmark on it. The

   mail that arrives after the main post office has done their

   pickup should have the following day's postmark on it. The

   changing of the postmark date stamp at this time is in

   conformity with the direction of the Mesa, Arizona, United

   States Post Office. We are not supposed to predate or postdate

   mail. The postmark should reflect the date that the mail will be

   picked up from our establishment by the Mesa, Arizona, 2000 Tax Ct. Memo LEXIS 416">*420 United

   States Post Office.

Mr. Noggle's declaration includes a sample of the postmark used by the postal contract unit at Impressive Greetings. The sample postmark matches the postmark on the envelope bearing the petition in this case.

This matter was called for a second hearing at the Court's motions session in Washington, D.C. Counsel for respondent again appeared and offered argument in support of respondent's motion to dismiss. Although no appearance was entered by or on behalf of petitioner at the hearing, petitioner again filed a written statement with the Court pursuant to Rule 50(c).

DISCUSSION

This Court's jurisdiction to redetermine a deficiency depends upon the issuance of a valid notice of deficiency and a timely filed petition. See 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 to the taxpayer at the taxpayer's2000 Tax Ct. Memo LEXIS 416">*421 "last known address". Sec. 6212(b); Frieling v. Commissioner, 81 T.C. 42">81 T.C. 42, 81 T.C. 42">52 (1983). The taxpayer, in turn, generally has 90 days from the date the notice of deficiency is mailed to file a petition in this Court for a redetermination of the deficiency. See sec. 6213(a).

There is no dispute that respondent mailed the notice of deficiency to petitioner at her last known address on January 6, 2000. Accordingly, the 90-day period for filing a timely petition with the Court expired on Wednesday, April 5, 2000. See sec. 6213(a). The petition in this case was not filed until April 7, 2000.

Although the petition was not timely filed, petitioner maintains that the petition was mailed to the Court on April 5, 2000 -- the 90th day after the mailing of the notice. Petitioner offered circumstantial evidence that Mr. Williams delivered the petition to the contract postal unit at Impressive Greetings late in the afternoon on April 5, 2000.

Section 7502 provides that, under certain circumstances, a timely-mailed petition will be treated as though it were timely filed. Section 7502(a) states in pertinent part:

   SEC. 7502(a). General Rule. --

     (1) Date Of2000 Tax Ct. Memo LEXIS 416">*422 Delivery. -- If any return, claim, statement, or

   other document required to be filed, * * * within a prescribed

   period or on or before a prescribed date under authority of any

   provision of the internal revenue laws is, after such period or

   such date, delivered by United States mail to the agency,

   officer, or office with which such return, claim, statement, or

   other document is required to be filed, * * * the date of the

   United States postmark stamped on the cover in which such

   return, claim, statement, or other document, or payment, is

   mailed shall be deemed to be the date of delivery or the date of

   payment, as the case may be.

In sum, section 7502(a) provides that if a petition is delivered to the Court by the U.S. Postal Service, then the date of the postmark stamped on the envelope bearing the petition shall be deemed the date of delivery. ²See sec. 301.7502-1(c)(1)(iii)(a), Proced. & Admin. Regs., which provides, in part, that "If the postmark does not bear a date on or before the last date, or the last day of the period, prescribed for filing the document, the document will be considered not to2000 Tax Ct. Memo LEXIS 416">*423 be filed timely, REGARDLESS OF WHEN THE DOCUMENT IS DEPOSITED IN THE MAIL." (Emphasis added.)

Based upon the record presented, we conclude that the petition was not timely filed pursuant to section 7502(a). Simply put, the U.S. Postal Service postmark date of April 6, 2000, affixed to the envelope bearing the petition, is conclusive proof that the petition was not timely filed under section 7502(a).

Petitioner offers extrinsic evidence that the petition was timely mailed on April 5, 2000. Although we allow extrinsic evidence to prove the date of mailing where an envelope lacks a postmark or the postmark is illegible, see Sylvan v. Commissioner, 65 T.C. 548">65 T.C. 548, 65 T.C. 548">553-555 (1975), such evidence is irrelevant in this case inasmuch as the envelope bears2000 Tax Ct. Memo LEXIS 416">*424 legible U.S. Postal Service postmarks dated after the 90th day prescribed for filing a timely petition. See Shipley v. Commissioner, 572 F.2d 212">572 F.2d 212 (9th Cir. 1977); Drake v. Commissioner, 554 F.2d 736">554 F.2d 736 (5(th) Cir. 1977); Kahle v. Commissioner, 88 T.C. 1063">88 T.C. 1063 (1987); Wiese v. Commissioner, 70 T.C. 712">70 T.C. 712 (1978); Hamilton v. Commissioner, T.C. Memo 1982-201. In conjunction with the foregoing, we note that the April 6, 2000 postmark date, a date 1 day before the petition was delivered to the Court, is not overtly erroneous on its face. See Harrison v. Commissioner, T.C. Memo 1990-458 (private postage meter postmark on envelope bearing a petition was treated as a nullity where the petition was delivered to the Court more than a week before the date of the postmark).

Petitioner cites Anderson v. Commissioner, 966 F.2d 487">966 F.2d 487 (9th Cir. 1992), for the proposition that she has offered sufficient evidence to invoke the common-law "mailbox" rule. Petitioner's reliance on 966 F.2d 487">Anderson v. Commissioner, supra, and the mailbox rule is misplaced.

The question presented in 966 F.2d 487">Anderson v. Commissioner, supra,2000 Tax Ct. Memo LEXIS 416">*425 was whether the taxpayer would be permitted to present extrinsic evidence of the date of mailing of a tax return where the Commissioner had no record of having received the return. Under the facts presented in that case, the Court of Appeals for the Ninth Circuit (1) rejected the Commissioner's argument that section 7502 presented the sole means for the taxpayer to prove the date of mailing of the missing tax return, and (2) allowed the taxpayer's extrinsic evidence. After sustaining the district court's holding that the taxpayer had established the date of mailing, the Court of Appeals went on to sustain the District Court's holding that the taxpayer could rely on the rebuttable presumption under the common law mailbox rule that a document properly and timely mailed is received by the addressee.

Contrary to petitioner's position, 966 F.2d 487">Anderson v. Commissioner, supra, does not stand for the broader proposition that a taxpayer may offer extrinsic evidence to rebut the date of a postmark affixed to an envelope bearing a petition filed with the Court. Indeed, in the course of its analysis, the Court of Appeals in 966 F.2d 487">Anderson v. Commissioner, supra, acknowledged its2000 Tax Ct. Memo LEXIS 416">*426 earlier holding in 572 F.2d 212">Shipley v. Commissioner, supra, that, in the absence of a receipt for certified mail, the taxpayer was precluded under section 7502 from introducing extrinsic evidence to prove that the postmark date affixed to the envelope bearing a petition filed with the Court was incorrect.

Although the circumstances leading to the late filed petition in this case are unfortunate, we note that the mailing of the petition on the 90th day raised "the spectre of possible timeliness problems" requiring a heightened degree of care in the mailing process. See 554 F.2d 736">Drake v. Commissioner, supra at 739. Moreover, although we lack jurisdiction in this case, petitioner is not without a remedy. In short, petitioner may pay the tax, file a claim for refund with the Internal Revenue Service, and if the claim is denied, sue for a refund in the Federal District Court or the Court of Federal Claims. See 554 F.2d 736">id. at 739; McCormick v. Commissioner, 55 T.C. 138">55 T.C. 138, 55 T.C. 138">142 (1970). Consistent with the preceding discussion, we shall grant respondent's Motion to Dismiss for Lack of Jurisdiction.

To give effect to the foregoing,

An order of dismissal for lack of2000 Tax Ct. Memo LEXIS 416">*427 jurisdiction will be entered.
