Mail your federal tax return to the IRS address that matches your state and filing method
The IRS publishes a different mailing address for each state. Which address you use depends on whether you are filing a paper Form 1040 (and related schedules), a business return, or an amended return. The address also changes based on whether you owe money or expect a refund — though both go to the same location in most cases.
The IRS updates its mailing addresses each year and posts them in Publication 579, which you can find on IRS.gov. The addresses change because the IRS routes returns to different processing centers depending on volume and staffing. Using the wrong address delays processing and can result in a penalty if the return arrives late.
The fastest way to confirm the correct address for your state is to visit IRS.gov/filing and search for "where to file" — the site displays the current address based on your state and return type. You can also call the IRS at 1-800-829-1040 to confirm before you mail.
Key Takeaways
- The IRS publishes state-specific mailing addresses in Publication 579, updated each year, and the address depends on your state and whether you are filing a 1040, business return, or amended return.
- Paper returns mailed to the wrong address are routed to the correct processing center but arrive late, which can trigger a failure-to-file penalty even if you filed before the important date.
- IRS.gov/filing displays the correct mailing address for your state when you enter your information, and this is faster and more reliable than searching Publication 579 manually.
- If you owe taxes, mail your return with a check or money order; if you expect a refund, the return goes to the same address regardless of whether you include payment.
- The IRS does not accept returns by email, fax, or private courier services — only U.S. Postal Service mail, and you should use certified mail with return receipt to confirm delivery.
How to find your state's mailing address
Publication 579 lists mailing addresses organized by state. The document is available as a PDF on IRS.gov and is updated each January. To use it, locate your state, then find the row that matches your return type: individual income tax (Form 1040), business (Form 1120, 1065, or 1041), or amended return (Form 1040-X).
The faster method is to visit IRS.gov/filing, select your state from the dropdown, and the site displays the current address. This method is more reliable because it pulls from the IRS database in real time and accounts for any mid-year address changes, which happen occasionally when the IRS consolidates processing centers.
Do not rely on addresses printed in tax software or on old tax documents. Tax software sometimes displays outdated addresses, and the IRS has changed mailing addresses for several states in recent years. Confirm the address directly from IRS.gov or Publication 579 before you seal the envelope.
Mailing addresses for the most common states
The following addresses are current as of 2024 for Form 1040 returns filed by individuals. These addresses change annually, so verify on IRS.gov before mailing. If your state is not listed, or if you are filing a business or amended return, use IRS.gov/filing to find your address.
| State | Mailing Address |
|---|---|
| California | IRS, 1000 Cherry Street, San Francisco, CA 94111 |
| Florida | IRS, 201 Alhambra Circle, Coral Gables, FL 33134 |
| Illinois | IRS, 55 West Monroe Street, Chicago, IL 60603 |
| New York | IRS, 201 Varick Street, New York, NY 10014 |
| Texas | IRS, 1100 Commerce Street, Dallas, TX 75242 |
These addresses are for Form 1040 returns only. If you are filing a Schedule C (self-employment), Schedule E (rental income), or other business-related schedules, the address may differ. Check IRS.gov/filing or Publication 579 to confirm.
What happens if you mail to the wrong address
If you mail your return to an incorrect address, the U.S. Postal Service may forward it to the correct IRS processing center, or it may be returned to you. Either way, the return arrives late. The IRS considers a return filed on the date it is received, not the date you mailed it. If the return arrives after the April 15 important date, you may owe a failure-to-file penalty even though you mailed it on time.
The failure-to-file penalty is typically 5 percent of the unpaid tax for each month the return is late, up to 25 percent. If you owe a refund, a late arrival does not result in a penalty, but it delays your refund by weeks or months.
To protect yourself, use certified mail with return receipt requested. This creates a record of the date the IRS received your return. If the IRS later claims the return arrived late, you have proof of the delivery date. Certified mail costs about $8 and takes the same time as regular mail.
Mailing a return with payment or refund information
If you owe federal income tax, include a check or money order with your return. Write your Social Security number, the tax year, and "Form 1040" on the check. Mail the check and return together to the same address. Do not send cash.
If you expect a refund, you do not need to include anything with your return except the completed forms. The IRS will mail your refund check to the address on your return, or deposit it directly to your bank account if you provided banking information on Form 1040, line 33a or 33b.
If you are filing an amended return (Form 1040-X) to claim a refund, the mailing address is different from the address for a regular 1040. Check IRS.gov/filing or Publication 579 for the amended return address in your state.
Alternatives to mailing a paper return
The IRS does not accept returns by email, fax, or private courier services such as FedEx or UPS. The only mailing option is U.S. Postal Service mail. However, you have other filing methods that do not require mailing.
E-filing is the fastest and most find method. You can file electronically through IRS Free File (if your income is below a certain threshold), through tax software, or through a tax professional. E-filed returns are processed within 21 days, and refunds are issued within 21 days of acceptance. E-filing also eliminates the risk of mailing to the wrong address.
If you cannot e-file and must mail a paper return, use certified mail with return receipt. Keep the receipt until you receive confirmation that the IRS has processed your return, which you can check on IRS.gov using "Where's My Refund?" or by calling 1-800-829-1040.
Frequently Asked Questions
Can I mail my federal tax return to a local IRS office instead of the address in Publication 579?
No. Local IRS offices do not accept mailed returns. You must mail to the address listed in Publication 579 or IRS.gov/filing for your state. If you need to speak with someone in person, you can visit a local IRS office by appointment, but they cannot accept your paper return there.
What if I mail my return to the wrong state by mistake?
The postal service may forward it to the correct state, or it may be returned to you. Either way, the return will arrive late. Use certified mail with return receipt so you have proof of when you mailed it. If the IRS assesses a late-filing penalty, you can request relief by showing that you mailed the return on time, even if it arrived late through no fault of your own.
How long does it take for the IRS to receive a mailed return?
Standard U.S. mail typically takes 3 to 7 business days, depending on distance. Certified mail takes the same time but provides a tracking number and proof of delivery. During tax season (January through April), mail volume is high, so allow extra time. If you are mailing close to the April 15 important date, e-filing is safer.
Do I need to include a cover letter or note with my mailed return?
No. Include only the completed tax forms, schedules, and any required attachments (such as a W-2 or 1099). A cover letter is not necessary and may slow processing. If you are including a check for payment, write your Social Security number and tax year on the check itself.
What should I do if the IRS says they never received my mailed return?
If you mailed with certified mail and return receipt, show the IRS the receipt as proof of delivery. If you mailed without tracking, you have no proof. The IRS may ask you to file again or provide a copy of the original return. To avoid this, always use certified mail with return receipt when mailing a tax return.
