A married couple’s petition for redetermination of an income tax deficiency was untimely where they electronically filed their petition from the central time zone but after the due date in the eastern time zone, where the Tax Court is located. Accordingly, the taxpayers’ case was dismissed for lack of jurisdiction.

The deadline for the taxpayers to file a petition in the Tax Court was July 18, 2022. The taxpayers were living in Alabama when they electronically filed their petition. At the time of filing, the Tax Court‘s electronic case management system (DAWSON) automatically applied a cover sheet to their petition. The cover sheet showed that the court electronically received the petition at 12:05 a.m. eastern time on July 19, 2022, and filed it the same day. However, when the Tax Court received the petition, it was 11:05 p.m. central time on July 18, 2022, in Alabama.

Electronically Filed Petition

The taxpayers’ petition was untimely because it was filed after the due date under Code Sec. 6213(a). Tax Court Rule 22(d) dictates that the last day of a period for electronic filing ends at 11:59 p.m. eastern time, the Tax Court’s local time zone. Further, the timely mailing rule under Code Sec. 7502(a) applies only to documents that are delivered by U.S. mail or a designated delivery service, not to an electronically filed petition.
