*129 On Sept. 28, 1971, respondent mailed to petitioners a statutory notice of deficiency covering Federal income taxes for the years 1968 and 1969. On Dec. 20, 1971, the petitioners, acting through their accountant, prepared an informal petition on the explanation of adjustments page attached to the notice of deficiency and sent it by first-class mail in an envelope addressed to the "Internal Revenue Service, Attention: Tax Court of United States, 200 No. Los Angeles, Calif." The petition was received on Dec. 28, 1971, by the Notices Section, Audit Division, Internal Revenue Service, in Los Angeles. On Dec. 29, 1971, the Internal Revenue Service forwarded the petition to this Court and it was received on Jan. 3, 1972, which was 97 days after the notice of deficiency was mailed. Held: (1) The delay caused by the erroneous mailing of the petition to the Internal Revenue Service deprives the Tax Court of jurisdiction; and (2) the petition was not timely filed "with the Tax Court" within the period prescribed by secs. 6213(a) and 7502(a),
*257 OPINION
This case is before us on respondent's motion to dismiss for lack of jurisdiction.
Petitioners' legal residence was in Lakewood, Calif., when they filed *131 their petition in this proceeding.
A statutory notice of deficiency was mailed by respondent to the petitioners on September 28, 1971, determining income tax deficiencies of $ 1,513.26 for 1968 and $ 1,641.06 for 1969. On December 20, 1971, the petitioners, acting through their accountant, prepared an informal petition at the bottom of the explanation of adjustments page attached to the notice of deficiency. This was sent by first-class mail in an envelope bearing a postmark date of December 20, 1971, and addressed to the "Internal Revenue Service, Attention: Tax Court of United States, 200 No. Los Angeles, Calif." The petition was received by the Notices Section, Audit Division, Internal Revenue Service, Los Angeles, on December 28, 1971. The Internal Revenue Service forwarded the petition to the United States Tax Court in Washington, D.C., on December 29, 1971. It was received by the Tax Court on January 3, 1972, which was 97 days after the notice of deficiency was mailed.
On February 28, 1972, respondent filed a motion to dismiss the case for lack of jurisdiction on the ground that the petition was not filed within the time prescribed by sections 6213(a) and 7502(a),
Section 6213(a) provides that a petition must be filed with the Tax Court within 90 days after the statutory notice of deficiency is *258 mailed to the taxpayer. The 90-day filing requirement is jurisdictional and this Court does not acquire jurisdiction of the case unless the petition is timely filed.
Petitioners argue that the envelope containing their petition was postmarked within the 90-day period although it was erroneously and improperly addressed to, and received by, the Internal Revenue Service in Los Angeles. Hence they contend that they have met the 90-day filing requirement of the statute.
We cannot agree. Section 6213(a) provides that the petition must be filed "with the Tax Court." See also Rule 1(b) of the Tax Court Rules of Practice. In
Since the only envelope containing the petition on which there was a timely postmark was not properly addressed, the petition was not timely filed under the provisions of section 7502, and since the envelope in which the petition was ultimately delivered to the Tax Court was not received by the Tax Court within the 90-day period and did not bear a timely postmark, the petition was not timely filed under the provisions of section 6213, so the Tax Court has no jurisdiction.
*259 Here, too, the envelope containing the petition with a timely postmark (Dec. 20, 1971) was not properly addressed, and the envelope in which the petition was ultimately delivered to the Court was not received*135 by the Court within the 90-day period and did not bear a timely postmark date.
We have no authority to extend the period provided by law for filing a petition with the Tax Court whatever the equities of a particular case may be and regardless of the cause for its not being filed within the required period. The mailing of a petition to the Internal Revenue Service is manifestly not filing it with the Tax Court. In fact, the Internal Revenue Service was under no legal obligation to forward the petition to the Court. See
Under the circumstances we hold that the petition was not timely filed. 1 Consequently, respondent's motion to dismiss for lack of jurisdiction will be granted. We note, however, that despite the mistake made by petitioners' representative in improperly addressing the envelope, the petitioners will still be able to have their day in court by paying the deficiencies and bringing a suit for refund in the U.S. District Court.
*136 An appropriate order will be entered.
