You're staring at a stack of paper. Maybe you’re one of the millions who still prefers the tactile security of a physical form, or perhaps your specific tax situation—like a complex 1040-NR or a niche attachment—forces your hand. Most people e-file. It’s fast. But for the paper-bound crowd, the question of where do i send tax return forms is actually a moving target that depends entirely on your geography and whether you’re enclosing a check.
Don't just guess. Sending a return to the wrong IRS service center is a recipe for a multi-month delay. The IRS isn't a single building in D.C. It’s a massive, fragmented network of processing centers in cities like Austin, Kansas City, and Ogden. If you live in New York and send your return to the Fresno address, it eventually gets rerouted, but you’ll be waiting forever for that refund.
The Geography of Your Tax Return
The IRS splits the United States into regions. These regions change occasionally as the agency closes or consolidates processing centers. For example, the Covington, Kentucky center stopped processing paper returns a few years ago, shifting that load elsewhere.
Basically, you need to know your "home" center. If you live in Florida, Louisiana, Mississippi, or Texas, you're looking at the Austin Service Center. But wait—that only applies if you aren't sending a payment. If you're attaching a check or money order, the address changes to a P.O. Box in Charlotte. Why? Because the IRS uses "lockbox" banks to process payments faster than the tax forms themselves. They want that cash in the Treasury immediately, while the 1040 can sit in a crate for a bit.
If You Live in California or the West
Westerners usually look toward Ogden, Utah. Residents of Alaska, Arizona, California, Colorado, Hawaii, Idaho, Nevada, New Mexico, Oregon, Utah, Washington, and Wyoming typically mail their returns to the Ogden Service Center.
If you're in California and you don't have a payment, you'd mail it to:
Department of the Treasury, Internal Revenue Service, Ogden, UT 84201-0002.
If you do have a payment, it goes to a different zip code in Charlotte, North Carolina. It’s a weirdly bifurcated system. You're essentially sending your money to the East Coast and your paperwork to the mountains.
The Mid-Atlantic and Northeast Hustle
For folks in Connecticut, Delaware, District of Columbia, Maine, Maryland, Massachusetts, New Hampshire, New Jersey, New York, Pennsylvania, Rhode Island, Vermont, or West Virginia, the destination is usually Kansas City, Missouri.
Wait.
Let me clarify that. It depends on the year and the specific form. For a standard 1040, Kansas City is the hub. If you are a resident of these states and not enclosing a payment, use:
Department of the Treasury, Internal Revenue Service, Kansas City, MO 64999-0002.
Why the Address Changes When You Owe Money
It feels like a trap. It isn't. The IRS uses a "Lockbox" system. These are specialized financial institutions—think big banks like J.P. Morgan Chase or Wells Fargo—that have a contract with the government to handle physical checks.
When you ask where do i send tax return with a check included, you are being directed to one of these banks. They rip open the envelope, scan the check, deposit the funds, and then forward the actual tax return to the IRS. This is why the "with payment" addresses often point to places like Charlotte, NC; Louisville, KY; or St. Louis, MO.

If you ignore this and send your check to the standard processing center, it’s not the end of the world. It just adds "transit time." Your check will sit in a mailroom pile instead of going straight to the bank.
Special Cases: International and Military
Are you living in a foreign country? Or perhaps you’re American Samoa, Guam, or Puerto Rico? Maybe you’re military with an APO/FPO address.
In these cases, you are almost always sending your return to:
Department of the Treasury, Internal Revenue Service, Austin, TX 73301-0215, USA.
There are no regional variations for international filers. Austin handles the world.
The Checklist Before You Lick the Envelope
Honestly, most people mess up the small stuff. It’s not just about the address.
- Sign the thing. You would be shocked how many people spend hours on math and forget to sign the bottom of the second page. A paper return without a signature is legally invalid. The IRS will eventually mail it back to you, asking for a signature, which adds months to the timeline.
- Attach your W-2s. You need to staple your W-2s and any 1099s that show federal tax withholding to the front of the return.
- Use the right postage. A standard 1040 with a few schedules is too heavy for a single "Forever" stamp. If the post office returns it for insufficient postage, you might miss the April 15th deadline.
- Certified Mail. This is the "pro tip" most tax experts insist on. Spend the extra five bucks for Certified Mail with a Return Receipt. This is your only legal proof that you actually filed on time if the IRS claims they never got it.
The 2026 Reality of Paper Filing
Let's be real for a second. The IRS is currently undergoing a massive modernization effort funded by the Inflation Reduction Act. They are getting better at scanning paper, but they still hate it.
A paper return can take 6 to 8 weeks to process under perfect conditions. In a bad year? Think 6 months. If you are wondering where do i send tax return because you're worried about privacy or "the cloud," just know that your paper return eventually gets manually typed into a computer by an IRS employee anyway. You aren't staying off the grid; you're just moving slower.
Detailed Address Breakdown (No Payment Enclosed)
If you are expecting a refund or just filing a zero-balance return, here is where the primary regions send their 1040s as of the 2025/2026 cycle:
- Florida, Louisiana, Mississippi, Texas: Austin, TX 73301-0002.
- Alaska, Arizona, California, Colorado, Hawaii, Idaho, Nevada, New Mexico, Oregon, Utah, Washington, Wyoming: Ogden, UT 84201-0002.
- Arkansas, Illinois, Indiana, Iowa, Kansas, Michigan, Minnesota, Montana, Nebraska, North Dakota, Oklahoma, South Dakota, Wisconsin: Fresno, CA 93888-0002. (Note: Some of these may shift to Kansas City depending on volume).
- Alabama, Georgia, Kentucky, Missouri, New Jersey, North Carolina, South Carolina, Tennessee, Virginia: Kansas City, MO 64999-0002.
- Connecticut, Delaware, District of Columbia, Maine, Maryland, Massachusetts, New Hampshire, New York, Pennsylvania, Rhode Island, Vermont, West Virginia: Kansas City, MO 64999-0002.
What If You’re Filing an Extension?
Filing Form 4868 is a different beast. You don't necessarily send the extension to the same place as the return. If you're mailing a paper extension and you live in a "middle" state like Ohio or Michigan, you often send it to Kansas City.
But again, why mail an extension? You can "file" an extension for free by making a tiny payment of $1 via IRS Direct Pay. That counts as an electronic extension and saves you the trip to the post office.
Common Misconceptions About Mailing Tax Returns
One big myth is that you can drop your return off at a local IRS Taxpayer Assistance Center (TAC). While these offices exist in most major cities, they aren't setup to "process" returns. They might take it from you and put it in their internal mail, but it’s no faster than the post office. Sometimes it’s slower.
Another mistake: using a private delivery service (PDS) like FedEx or UPS for a P.O. Box address. FedEx and UPS cannot deliver to IRS P.O. Boxes. If the address provided by the IRS is a P.O. Box, you must use the United States Postal Service. If you absolutely want to use FedEx, you have to look up the "street address" for that specific submission processing center.
For example, the Ogden street address for private couriers is:
Internal Revenue Service, 1973 Rulon White Blvd., Ogden, UT 84201.
Actionable Steps for Your Paper Return
Ready to mail? Do these three things right now to ensure you don't end up in tax purgatory.
First, double-check the IRS Interactive Tax Assistant on IRS.gov. Just type "Where to File" into their search bar. It will ask for your state and the form you're filing. This is the only way to be 100% sure an address hasn't changed last-minute due to a facility closure or overflow redirect.
Second, make a full photocopy of every single page, including the signed signature page and every schedule. If the mail truck catches fire or a clerk in Austin spills coffee on your return, you need an exact replica of what you sent.
Third, place your check on top. If you owe money, don't hide the check inside the 100-page return. The IRS prefers you don't staple the check to the return. Use a paperclip or just leave it loose inside the envelope with Form 1040-V (the Payment Voucher). This ensures the "Lockbox" bank sees the money immediately.

Finally, check the postmark. If you’re mailing on April 15th, you need to make sure the post office actually stamps it today. A "received" date by the IRS doesn't matter for the deadline; the "postmark" date does. If you drop it in a blue box at 9:00 PM and the mail isn't collected until the 16th, you are officially late.
