Where to Mail Your Federal Income Tax Return

Mail your return to the IRS service center for your state

The address where you send your federal tax return depends on which state you live in and whether you are including a payment. The IRS operates 10 regional service centers across the country, and each one handles returns from specific states. Sending your return to the wrong address delays processing and can trigger notices.

If you live in Alabama, Georgia, or North Carolina, you mail to the Atlanta service center. If you live in Connecticut, Maine, Massachusetts, New Hampshire, Rhode Island, or Vermont, you mail to the Andover, Massachusetts center. The IRS website lists the complete routing by state, and the address also appears in the instructions that come with Form 1040 and on the back of the form itself.

The address changes slightly depending on whether you are including a check or money order. If you owe money and are sending payment with your return, use the payment address. If you are not sending payment, use the non-payment address. Using the wrong one does not reject your return, but it may slow down processing by a few weeks.

How to find the correct address for your state

The IRS publishes the mailing addresses in the instructions for Form 1040, which you can read from IRS.gov. Open the PDF, go to the section titled "Where to File," and find your state in the list. The document shows two addresses side by side: one for returns with payment and one for returns without payment.

You can also find the addresses on the IRS website by searching "where to file" or "IRS mailing addresses." The page lists all 10 service centers and the states each one serves. Write down the full address, including the ZIP code, before you seal your envelope. The ZIP code matters because it routes your mail to the correct processing facility within the service center.

Mailing addresses for returns with and without payment

If you are sending a check or money order with your return, use the payment address. This address routes your envelope to the department that processes payments first, which reduces the chance of your check being lost or misplaced. The payment address is usually a different building or processing center than the non-payment address, even within the same city.

If you are not sending payment—because you are owed a refund or because you will pay by other means—use the non-payment address. Do not send a payment to the non-payment address, because it will be routed to a different facility and processing will take longer. The two addresses are printed side by side in Form 1040 instructions so you can compare them before you mail.

What to include with your return when you mail it

Use a standard business envelope or a larger envelope if your return includes schedules or supporting documents. Write the correct mailing address on the front in black or blue ink. Do not use a marker or pencil. Include your name and address in the upper left corner so the post office can return the envelope if it cannot be delivered.

If you are sending a payment, write your Social Security number, tax year, and form number on the front of your check or money order. Do not staple the check to your return; paper-clip it to the front of Form 1040 instead. Staples can jam the IRS scanning equipment and delay processing.

Keep a copy of your return and any supporting documents for your own records. The IRS does not return copies of what you mail, so you will not see your original documents again. If you want proof that the IRS received your return, send it by certified mail with return receipt requested. This costs a few dollars but gives you a tracking number and a signature confirmation.

Processing time for mailed returns

The IRS typically processes mailed returns within 21 days of receiving them, though the actual time varies depending on the service center's workload and the complexity of your return. During tax season (January through April), processing can take longer because the service centers receive thousands of returns per day.

If your return includes a refund, the IRS will mail you a check or deposit the money into your bank account, depending on how you requested it on the form. Refunds by mail take an additional 7 to 10 business days after the IRS processes your return. If you chose direct deposit, the refund usually arrives within 3 to 5 business days after processing.

You can track the status of your return on the IRS website using the "Where's My Refund?" tool. This tool updates once per day and shows whether the IRS has received your return and whether it is being processed. You will need your Social Security number, filing status, and the refund amount to use the tool.

Why electronic filing is faster than mailing

If you file electronically using tax software or a tax professional, your return goes directly to the IRS computer system and does not need to be mailed. Electronic returns are processed within 24 hours in most cases, compared to 21 days or more for mailed returns. The IRS also accepts electronic returns year-round, whereas mailed returns must arrive by the tax important date to be considered on time.

Electronic filing also reduces the chance of errors because the software checks your math and flags missing information before you submit. If you mail a return with an error, the IRS will send you a notice and you will have to correct it by mail, which takes weeks. With electronic filing, errors are caught before submission.

Many people can file electronically for free using IRS Free File, which is available through the IRS website if your income is below a certain threshold. Even if you do not may have access to for free filing, commercial tax software is often cheaper than paying a tax professional to prepare and mail a paper return.

What happens if you mail your return to the wrong address

If you mail your return to an address that does not serve your state, the post office may forward it to the correct service center, or it may be returned to you as undeliverable. Either way, processing is delayed. If the post office forwards it, add 1 to 2 weeks to the normal processing time. If it is returned to you, you will have to mail it again to the correct address.

The IRS does not penalize you for mailing to the wrong address, but the delay can cause problems if your return is due soon. If you are close to the tax important date and you are not sure which address is correct, file electronically instead. Electronic filing is faster and eliminates the risk of mailing to the wrong place.

If you realize you mailed to the wrong address after you have already sent it, contact the IRS at 1-800-829-1040 to report it. The IRS can sometimes locate your return and reroute it, but this is not may provide. In the future, double-check the address against Form 1040 instructions before you seal the envelope.

Frequently Asked Questions

Can I mail my return to any IRS office, or does it have to go to my state's service center?

You must mail to the service center that handles your state. Mailing to a different IRS office will delay processing because the office will have to forward your return to the correct service center. The address for your state is listed in Form 1040 instructions and on the IRS website.

Do I need to use certified mail when I send my tax return?

Certified mail is optional but recommended if you want proof that the IRS received your return. Standard mail is fine and will reach the IRS, but you will not have a tracking number or signature confirmation. If you use standard mail, keep a copy of your return for your records.

What if I mail my return but forget to include my payment?

The IRS will process your return and send you a bill for the amount you owe, plus interest and penalties that accrue from the original important date. Pay the bill as soon as you receive it to minimize the interest. In the future, use a checklist before you seal the envelope to make sure the check is attached.

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

You can check the status using the "Where's My Refund?" tool on the IRS website once the IRS has processed your return. The tool updates once per day and shows whether your return has been received and processed. If you sent your return by certified mail, you will also have a delivery confirmation from the post office.

Is it better to mail my return or file electronically?

Electronic filing is faster, more accurate, and reduces the risk of your return being lost in the mail. Mailed returns take 21 days or longer to process, while electronic returns are processed within 24 hours. If you have the option to file electronically, that is the better choice.
