The IRS has different mailing addresses depending on whether you owe money or expect a refund

Your federal tax return goes to one of two IRS addresses. The address you use depends on whether you are sending a payment with your return or filing without payment. If you are mailing a paper return, the IRS processes returns sent to the wrong address more slowly, so matching your situation to the correct address matters.

The IRS publishes a full list of mailing addresses in the instructions that come with your tax form — usually Form 1040 instructions for individual returns. You can also find the correct address on the IRS website by searching "where to file" or by looking at the back of the form itself. The address changes slightly from year to year, so always check the current year's form or instructions before you mail.

Key Takeaways

  • Returns with a payment go to a different address than returns without payment, and sending to the wrong address delays processing.
  • The correct mailing address for your state and situation appears in the instructions that come with your tax form or on the IRS website.
  • The IRS mailing addresses change each year, so check the current year's form or instructions rather than using an old address.
  • E-filing through tax software or a tax professional is faster and more reliable than mailing a paper return.

How to find the right mailing address for your return

Open the instructions for the form you are filing — usually Form 1040 for individual returns, Form 1120 for corporations, or Form 1065 for partnerships. Near the end of the instructions, there is a section titled "Where to File" or "Mailing Addresses." This section lists addresses by state and by whether you are sending a payment.

If you do not have the printed instructions, you can read them from the IRS website at irs.gov. Search for the form number and year, and the instructions will appear as a PDF. The mailing address section is always near the back. You can also call the IRS at 1-800-829-1040 and ask for the correct address for your state and situation, though wait times are often long during tax season.

Mailing a return with a payment versus without

If you are sending a check or money order with your return, you use one address. If you are filing without payment — because you expect a refund or have no tax owed — you use a different address. The IRS separates these streams to route payments to the right processing center.

Write your Social Security number or employer identification number on your check or money order, along with the tax year and form type. Do not send cash. Mail your return and payment together in the same envelope. If you are not sending a payment, mail only the return itself to the address listed for returns without payment.

Why the mailing address changes every year

The IRS consolidates processing centers and updates addresses regularly. An address that was correct last year may not work this year, or it may work but process returns more slowly. Using an outdated address does not prevent the IRS from receiving your return, but it can add weeks to processing time.

The safest approach is to check the address in the current year's form instructions every time you file. If you are using tax software or a tax professional, they usually print the correct address on the return itself, so you do not have to look it up separately.

E-filing as an alternative to mailing

The IRS accepts electronic returns through tax software, tax professionals, and free filing services. E-filed returns are processed faster than mailed returns — usually within two to three weeks if you are due a refund, compared to four to six weeks or longer for paper returns. You also get an electronic confirmation that the IRS received your return.

The IRS Free File program offers free e-filing to people who earn below a certain income threshold, which varies by year. If you do not meet the income limit, commercial tax software costs between $0 and $200 depending on the complexity of your return and the provider. A tax professional — a CPA, enrolled agent, or tax preparer — can also file electronically on your behalf for a fee.

What to do if you are unsure about the address

If you have already mailed your return to an address you are not certain about, do not mail it again. The IRS will receive it eventually, even if it goes to the wrong processing center first. It will straightforward take longer. If you have not yet mailed your return, take five minutes to check the current year's form instructions or the IRS website before you send it.

If you are filing a return for a prior year (not the current tax year), the address may be different. The IRS publishes separate instructions for amended returns on Form 1040-X, which also include a mailing address. Always use the instructions for the year you are filing, not the year the return covers.

Frequently Asked Questions

Can I mail my return to any IRS office?

No. The IRS has specific processing centers, and returns mailed to a local IRS office or the wrong state address will be rerouted, which delays processing. Always use the address listed in the current year's form instructions for your state and situation.

What if I mail my return and do not get a confirmation?

Paper returns do not come with a receipt. If you want proof the IRS received your return, send it by certified mail with return receipt requested. The receipt shows the IRS received the envelope, though it does not confirm they processed the return itself. E-filing gives you an electronic confirmation instead.

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

No. The IRS does not require a cover letter. Include only the completed tax form, schedules, and any required attachments. If you are sending a payment, include the check or money order. A cover letter may actually slow processing because it has to be separated from the return.

What address do I use if I live outside the United States?

The IRS publishes a separate mailing address for returns from people living abroad. This address appears in the Form 1040 instructions under the "Where to File" section. If you are a U.S. citizen or resident alien living outside the country, check that section rather than using a domestic address.
