Where do I mail my Form 1040 tax return?

First — are you mailing a tax return or a tax extension?

If you filed a tax extension with us (Form 4868), you don't need to mail anything yourself — we handle that electronically. If you chose the free print-and-mail extension option, see How to Find and Download Your Tax Extension Forms for that address instead. This article is for mailing a completed 1040 tax return.

Find your mailing address

The correct address depends on two things: your state, and whether you're including a payment.

1. Go to the IRS's official address list: Where to File Paper Tax Returns
2. Find your state in the table.
3. Use the "with payment" address if you're mailing a check or money order — otherwise use the "without payment" address.

A few things to know before you mail it

• Include any required schedules (Schedule 1, 2, or 3) — a missing schedule can delay processing.
• Paying by check? Make it payable to "United States Treasury." You can also pay electronically instead at IRS Direct Pay, even if you're mailing the return itself.
• Mailed returns take longer to process than e-filed ones — the IRS recommends e-filing when possible.
