Tuesday is the deadline to file 2017 federal tax returns, and an Anchorage post office open until 11 p.m. can postmark the returns of last-minute filers.
All post offices in Alaska will operate under regular hours Tuesday, the U.S. Postal Service said.
But the Anchorage airport post office at 4141 Postmark Drive is open 8 a.m. to 11 p.m. and offers the latest collection time in the state, according to the Postal Service.
Residents using other Alaska post offices are encouraged to mail returns early in the day and check the collection times on each mail drop box to ensure Tuesday pickup.
