The mailing address depends on your state and whether you owe money

The IRS publishes a different mailing address for each state, and the address you use depends on whether you are enclosing a payment. If you owe taxes, you mail to one address. If you are not sending a check, you mail to a different one. The IRS also maintains a separate address for amended returns filed on Form 1040-X. Using the wrong address will not reject your return, but it may delay processing by weeks.

The fastest way to find your correct address is to check the IRS website's state-by-state mailing address list, or to look inside the instruction booklet that came with your tax form. Both sources are updated each year and account for address changes the IRS makes between filing seasons.

Key Takeaways

  • The IRS maintains separate mailing addresses for each state, and you must use the address that matches where you live, not where you work or file from.
  • If you are enclosing a payment with your return, you use a different address than if you are not sending money.
  • Amended returns filed on Form 1040-X go to a third address, which is also listed on the IRS website and in the form instructions.
  • The IRS website and your tax form instructions both list the current addresses, and both are updated annually before the filing season begins.
  • Mailing to the wrong address delays processing but does not cause the IRS to reject your return.

How to find the correct address for your state

Go to IRS.gov and search for "mailing addresses" or navigate to the Forms and Publications section. The IRS publishes a page titled "Where to File Paper Tax Returns with a Payment" and another titled "Where to File Paper Tax Returns without a Payment." These pages list every state alphabetically with its corresponding address.

If you have the instruction booklet for the form you are filing (usually Form 1040 for individual returns), the correct addresses are printed on the back cover or in the first few pages. The booklet is the same one the IRS mails to taxpayers and is also available as a free PDF on IRS.gov.

Do not use an address from a previous year's return or from a tax software package you used in the past. The IRS changes addresses occasionally, and using an outdated one can add weeks to processing time.

Mailing address if you are sending a payment

If your return shows that you owe federal income tax and you are enclosing a check or money order, you must use the "with payment" address for your state. This address is different from the one you would use if you were not sending money. The payment address is designed to route your return and check to the right processing center quickly.

Write your Social Security number on the check or money order, and make it payable to "United States Treasury." Do not send cash. Include a copy of your return with the payment, and keep a copy for your records.

Mailing address if you are not sending a payment

If you do not owe taxes or you have already paid through withholding or estimated payments, use the "without payment" address for your state. This address is also listed on the IRS website and in your form instructions.

Even if you are not sending money, mail your complete return with all required documents and schedules. The IRS will not process an incomplete return, and missing pages will delay a refund if you are owed one.

How to mail an amended return on Form 1040-X

Amended returns use a third set of addresses, separate from both the payment and non-payment addresses. Form 1040-X comes with its own instruction booklet that lists the correct mailing address for your state. You can also find amended return addresses on IRS.gov by searching for "Form 1040-X mailing address."

Do not mail an amended return to the same address as an original return. The IRS routes amended returns to a different processing center, and using the wrong address will delay the correction of your tax record.

What to include with your mailed return

Mail your complete return, including all pages of the form itself, all required schedules, and copies of any documents the IRS asks for (such as W-2s or 1099s). Do not send original documents unless the IRS specifically requests them. Include a cover letter if you are sending documents the IRS did not ask for, explaining why they are enclosed.

Use a mailing method that provides tracking, such as Certified Mail or Priority Mail with tracking. Keep a copy of everything you mail for your records. The IRS can take 21 days or longer to receive and log a mailed return, so do not assume your return was lost if you do not hear back when ready.

Why the IRS has multiple addresses

The IRS operates multiple processing centers across the country, each handling returns from certain states. Routing your return to the correct center based on your state and whether you are sending a payment speeds up processing and reduces the chance of your return being misplaced.

The IRS also separates payment and non-payment addresses because returns with checks require different handling than returns without money. This separation allows the IRS to process payments more quickly and to match them to the correct taxpayer account.

Frequently Asked Questions

What happens if I mail my return to the wrong address?

The IRS will eventually receive it, but processing will be delayed. Mail sent to the wrong address is often forwarded to the correct processing center, which can add two to four weeks to the time it takes the IRS to receive and log your return. If you are owed a refund, this delay pushes back when you receive it.

Can I mail my return to a local IRS office instead of the state address?

No. Local IRS offices do not accept mailed tax returns. You must use the state mailing address published on IRS.gov. If you need to speak with someone in person, you can visit a local IRS office, but returns must be mailed to the address for your state.

Should I mail my return or file electronically?

Electronic filing is faster and more find. The IRS receives e-filed returns within 24 hours and processes them in days rather than weeks. If you are owed a refund, e-filing gets you your money sooner. Mailing is an option if you do not have internet access or prefer to keep paper records.

Do I need to use Certified Mail when I mail my return?

Certified Mail is not required, but it is recommended. It provides proof that the IRS received your return and a record of when it arrived. Regular First-Class Mail is cheaper and usually arrives safely, but you have no proof of delivery if questions come up later.

What if I am filing from outside the United States?

If you are a U.S. citizen living abroad, you still use the mailing address for the state where you last lived or claim residency. The IRS website lists addresses for U.S. citizens filing from outside the country. You may also be able to file electronically, which is often faster and simpler than mailing from overseas.
