The deadline for filing federal income tax returns with the federal Internal Revenue Service is midnight tonight.
But for North Olympic Peninsula residents, the reality of mailing their returns comes much earlier in the day.
No post offices on the Peninsula will stay open late.
Post offices will close and collect mail according to normal business hours, which range from 3 p.m. to 5 p.m.
Larger post offices on the Peninsula that will stay open and collect mail until 5 p.m. include Port Angeles, Sequim and Port Townsend.
People with specific questions about the latest time they can mail tax returns should call their local post office.
Post offices in Seattle and Tacoma will be open until midnight.
