Where to mail your federal tax return (Form 1040)
The IRS mailing address for a paper federal return depends on two things: your state of residence and whether you are enclosing a payment. No-payment Form 1040 returns go to the Department of the Treasury, Internal Revenue Service, in Austin TX 73301-0002, Kansas City MO 64999-0002, or Ogden UT 84201-0002 by state. Returns with a payment go to an IRS PO box in Charlotte NC or Louisville KY instead. Pick your situation below.

Key facts
- The single biggest mistake is using the no-payment address when you are enclosing a check. Payment returns go to a different IRS PO box (Charlotte NC or Louisville KY).
- No-payment returns are addressed to "Department of the Treasury, Internal Revenue Service" with only a city, state, and unique ZIP — there is no street line.
- Federal returns are normally due April 15; a USPS postmark on or before the deadline counts as filed on time.
- Amended returns (Form 1040-X) use the same three cities but a different ZIP suffix (-0052) and slightly different state groupings.
- PostPal prints and mails your return via USPS the next business day for $5 — and emails you dated proof of mailing.
How to send your letter
- 1
Decide: payment enclosed or not?
If you are mailing a check or money order with the return, you need the with-payment PO box for your state. If you owe nothing or are getting a refund, use the no-payment address above.
- 2
Find your state
Match your state of residence to Austin, Kansas City, or Ogden using the cards above (no payment) or the with-payment page. The IRS routes strictly by state — a return sent to the wrong centre is slower to process.
- 3
Sign, attach, and address
Sign and date the return, attach your W-2s and withholding 1099s, and address the envelope exactly as shown. The unique ZIP does the routing.
- 4
Mail it on time
Write your return in PostPal (or upload a PDF) and we print, envelope, and hand it to USPS within one business day for $5 — with a dated confirmation email as your proof of mailing.
Common questions
What is the IRS address to mail my 1040?
It depends on your state and whether you enclose a payment. With no payment, use Austin TX 73301-0002, Kansas City MO 64999-0002, or Ogden UT 84201-0002. With a payment, use the IRS PO box in Charlotte NC or Louisville KY for your state.
Does the address change if I owe money?
Yes. Returns enclosing a payment go to an IRS lockbox PO box (Charlotte, NC or Louisville, KY), not the no-payment processing-centre ZIP. Sending a payment to the wrong address can delay posting your payment.
Is there a street address for the IRS?
No-payment returns have no street address — the IRS uses a unique ZIP per centre. Payment returns use a PO box. In both cases the address shown is complete and deliverable.
When is my paper return due?
Federal individual returns are generally due April 15 (the next business day if that falls on a weekend or holiday). A USPS postmark on or before the due date counts as filed on time.
