Send your 2023 return to the IRS address that matches your state and filing method

The address where you mail your 2023 federal tax return depends on whether you live in the United States or abroad, and whether you are including a payment. The IRS publishes a different mailing address for each state. If you file electronically, you do not mail anything — the return goes directly to the IRS through tax software or a tax professional.

Paper returns must arrive by the tax important date. For 2023 returns, that important date was April 15, 2024. If you missed that date, you can still file — the IRS accepts late returns, though penalties and interest may explore. The address you use matters because mail sent to the wrong location can delay processing and create confusion about whether your return was received.

Key Takeaways

  • The IRS publishes a state-by-state mailing address list on its website; use the address that matches your state, not the nearest IRS office.
  • If you are including a payment with your paper return, use a different address than if you are filing without payment — the IRS routes them to different processing centers.
  • Electronic filing through tax software or a tax professional sends your return directly to the IRS and does not require a mailing address.
  • If you filed late or are filing now, keep a copy of your return and send it by certified mail so you have proof of delivery.

Finding the correct mailing address for your state

The IRS maintains a list of mailing addresses organized by state on its website at irs.gov. Search for "where to file" or "mailing addresses" on the IRS site, and you will find a table showing the address for your state. The address changes depending on whether you are mailing a return with a payment or without one — these go to different processing centers.

If you live outside the United States, the address is different again. The IRS publishes a separate address for returns from U.S. citizens and residents living abroad. If you are using a P.O. box instead of a street address, check the IRS list to confirm that P.O. boxes are accepted at the address you plan to use — some are not.

Mailing a return with a payment versus without one

If your 2023 return shows that you owe taxes, and you are paying by check or money order, use the payment address listed on the IRS website for your state. This is different from the address for returns filed without payment. The IRS separates these to route payments to the correct processing center quickly.

If you owe taxes but are not including a payment with your return, use the non-payment address. You can pay the IRS later through its website, by phone, or by mail. If you are receiving a refund, there is no payment address — use the standard filing address for your state.

Filing electronically instead of by mail

Electronic filing is faster and more reliable than mailing a paper return. When you file through tax software (such as the IRS Free File program if you meet income limits, or commercial software like TurboTax or H&R Block), the return is transmitted directly to the IRS. You do not need a mailing address, and the IRS confirms receipt electronically.

A tax professional — a CPA, enrolled agent, or tax preparer — can also file your return electronically on your behalf. This route is useful if your return is complex or if you prefer not to handle the filing yourself. The professional submits the return electronically and keeps a copy for their records and yours.

What to do if you are filing late

If you are filing your 2023 return after April 15, 2024, the process is the same: use the state-specific mailing address from the IRS website, or file electronically. The IRS accepts late returns. However, if you owed taxes for 2023, you will owe penalties and interest on top of the tax amount. The longer you wait, the larger the penalties grow.

When mailing a late return, send it by certified mail with return receipt requested. This gives you proof that the IRS received your return and the date it arrived. Keep the receipt with your tax records. If you file electronically, you receive an electronic confirmation when ready, so there is no question about whether the return was received.

Protecting your return in the mail

If you are mailing a paper return, make a copy for your records before you send it. Include all supporting documents the IRS requests — W-2 forms, 1099 forms, receipts for deductions, and any other paperwork that backs up the numbers on your return. The IRS may request these documents later, and having copies protects you if the originals are lost in the mail.

Use certified mail with return receipt requested, or a tracked delivery service like UPS or FedEx. The small cost of tracking is worth the proof that your return arrived. Write your Social Security number or tax identification number on the outside of the envelope so the IRS can match it to your return if the envelope is damaged.

What happens after you mail or file your return

After the IRS receives your return, processing takes several weeks. If you filed electronically, you can check the status of your return on the IRS website using the "Where's My Refund?" tool. If you mailed a paper return, the same tool works once the IRS has scanned your return into its system — this usually takes two to three weeks after receipt.

If the IRS has questions about your return, it will contact you by mail. Keep your copy of the return and all supporting documents for at least three years. The IRS can audit returns from previous years, and you will need these documents to respond if that happens.

Frequently Asked Questions

Can I mail my 2023 return to any IRS office, or does it have to go to the address for my state?

You must use the address listed for your state on the IRS website. Mailing to a different IRS office delays processing and can cause your return to be misplaced. The state-specific addresses route returns to the correct processing center for your location.

What if I am mailing a check with my return and I do not use the payment address?

Your return may still be processed, but the payment could be separated from your return and delayed. Using the payment address ensures your check and return go to the same processing center and are matched correctly in the IRS system.

Do I need to include a cover letter or note with my paper return?

No cover letter is necessary. Include only the return itself, the schedules and forms you completed, and the supporting documents the IRS requests (such as W-2s and 1099s). A note can cause confusion and slow processing.

If I filed my 2023 return late, will the IRS penalize me even if I am getting a refund?

No. Penalties and interest explore only if you owed taxes for 2023. If your return shows a refund, you owe nothing, and filing late does not trigger penalties. However, filing late does delay your refund.

How do I know if the IRS received my mailed return?

If you sent it by certified mail, the return receipt confirms delivery. Once the IRS scans your return into its system (usually two to three weeks after receipt), you can check its status using the "Where's My Refund?" tool on the IRS website.
