So, you went to work today, the deadline for mailing your federal and Arizona tax returns or extensions, and just remembered that you need to file? Here's what you need to do.
- Find forms or online software. Post offices do not have tax forms.
- Complete either tax returns or extensions (both federal and AZ)
- E-file or mail the returns before midnight.
Remember, even if you file an extension you must have it postmarked by midnight on this year's deadline date.
If you don't file electronically, you can still get your tax returns off in the mail on that day. Many post offices are open until 5 p.m., some until 6 p.m. You can find the hours of the U.S. Post Office closest to you by searching here using your zip code or by calling 1-800-275-8777. If you choose to deposit your tax returns in a blue collection box on April 18, make sure that you read the label on the box to make sure that that it is not past the last collection time for that box.
Post Offices and Satellites Open Late
If you need to mail your tax returns after 6 p.m. you can go to:
- U. S. Post Office
4949 E. Van Buren, Room 187
Phoenix, AZ 85026
Find this location on a map.
The window is on Van Buren Street, just east of 48th Street.
Full retail services, including stamps, Certified Mail and Registered Mail, will be available until 10 p.m.
How much postage do I need for my tax returns?
First class postage is 49 cents for the first ounce, 70 cents for 2 ounces, 90 cents for 3 ounces (as of January 2017).
You should have the post office compute it if your envelope is heavier or if you are sending your tax return in anything other than a regular #10 envelope. A rough estimate is that 4-5 pages of 8-1/2 x 11 paper (some paper is heavier than others) in a #10 envelope is about an ounce. If your mail is thicker or heavier, add more stamps!
It would be silly to risk a late filing penalty because of a stamp, wouldn't it?
