Title 26 › Subtitle F — Procedure and Administration › CHAPTER 77 — MISCELLANEOUS PROVISIONS › § 7503
If a tax return, form, or other required tax task is due on a Saturday, Sunday, or legal holiday, it counts as on time if you do it the next day that is not one of those days. Include any allowed extension when figuring the last day; "legal holiday" means DC holidays and, for IRS offices outside DC in the same internal revenue district, the State's statewide holidays.
