The mailing address depends on your state and whether you owe money or expect a refund
The IRS publishes a different mailing address for each state. You cannot mail your 1040 to a single national address — using the wrong one delays processing by weeks. The address you need is in IRS Publication 579, which lists every state's current mailing location. You can also find your state's address on the IRS website by searching "where to file" plus your state name, or by calling the IRS at 1-800-829-1040.
The address changes occasionally when the IRS consolidates processing centers, so always check the current year's instructions before you mail. Do not use an address from last year's return or from a friend's tax documents. The IRS processes returns faster when they arrive at the correct location on the first try.
Key Takeaways
- Each state has its own mailing address; using the wrong one adds weeks to processing time.
- IRS Publication 579 and the IRS website both list current addresses by state for the tax year you are filing.
- The address may differ depending on whether you are including a payment or not, so check the instructions that came with your form.
- Mail your return at least one week before the important date to account for postal delays, or file electronically to avoid mailing altogether.
- Keep a copy of your return and proof of mailing (such as certified mail receipt) for your records.
How to find your state's correct mailing address
Open IRS Publication 579 (available free on IRS.gov) and locate your state in the table. The publication lists two addresses for most states: one for returns with a payment enclosed, and one for returns without payment. Read the column headers carefully — they tell you which address to use based on your situation.
If you cannot access the publication online, call 1-800-829-1040 and give the representative your state. They will read you the address over the phone. Write it down exactly as they say it, including the ZIP code and any suite or building numbers.
The IRS website also has a search tool labeled "Where to File" that filters by state and filing status. This tool updates automatically when addresses change, so it is often the fastest way to confirm the current address before you print your envelope.
Mailing addresses for the most common states
| State | Address Type | General Location |
|---|---|---|
| California | With payment | Fresno, CA |
| California | Without payment | Fresno, CA |
| Florida | With payment | Jacksonville, FL |
| Florida | Without payment | Jacksonville, FL |
| New York | With payment | Andover, MA |
| New York | Without payment | Andover, MA |
| Texas | With payment | Austin, TX |
| Texas | Without payment | Austin, TX |
This table shows examples only. The IRS changes processing center locations periodically, so always verify the current address in Publication 579 or on IRS.gov before you mail. Do not rely on an address from a previous year or from another person's return.
What to include with your mailed return
Place your completed 1040 form, all schedules, and all supporting documents (W-2s, 1099s, receipts for deductions) inside the envelope. Do not staple or clip pages together; the IRS prefers them loose so they can be scanned separately. Write your Social Security number on the outside of the envelope in the upper left corner if your return is not in a window envelope.
If you are enclosing a payment, write a check or money order payable to "United States Treasury." Do not send cash. Write your Social Security number, the tax year, and "1040" on the memo line of the check. Include the check inside the envelope with your return, not in a separate envelope.
Use a standard business envelope or a larger envelope if your return has many pages. Address the envelope to the correct state address from Publication 579. Leave at least one-half inch of space on all sides of the address so the IRS scanning equipment can read it.
Mailing timeline and tracking
Mail your return at least one week before the tax important date to allow time for postal delivery. The IRS counts the postmark date as your filing date, not the date they receive it, so a return postmarked by April 15 is considered timely even if it arrives later. However, if the return is lost in the mail, you will need the postmark as proof you filed on time.
Use Certified Mail with Return Receipt if you want proof of delivery. The post office will give you a receipt showing the date mailed and a tracking number. Keep this receipt with your tax records. The cost is usually $3 to $5 and is worth it for peace of mind.
The IRS typically processes mailed returns within 21 days of receipt, though this varies by volume and time of year. If you filed electronically instead of mailing, processing is usually faster — often within 24 hours for returns with direct deposit refunds.
When not to mail your return
If you have a refund coming, filing electronically is faster and safer than mailing. Electronic filing processes refunds in as little as 24 hours with direct deposit, compared to several weeks for a mailed return. You can file electronically through IRS Free File (if your income is below a certain threshold), through tax software, or through a tax professional.
If you are mailing a payment, consider paying electronically through the IRS website instead. You can pay by debit card, credit card, or electronic bank transfer. Paying electronically reduces the risk that your check will be lost or delayed in the mail.
If your return is complex or you are unsure about any part of it, consider having a tax professional prepare and file it electronically. This reduces the chance of errors that could trigger an audit or delay processing.
Common mailing mistakes and how to avoid them
The most common error is using an outdated address from a previous year. The IRS consolidates processing centers periodically, and addresses change. Always check Publication 579 for the current year before you mail.
Another frequent mistake is mailing to the wrong address because you owe money. Some states have different addresses for returns with payments versus returns without payments. Read the column headers in Publication 579 carefully and use the address that matches your situation.
Do not mail your return to a local IRS office or a tax professional's office. These locations do not process individual returns. Mail only to the address listed in Publication 579 for your state.
Forgetting to sign and date your return is also common. The IRS will reject an unsigned return and send it back to you, which delays processing by several weeks. Sign your return in blue or black ink before you seal the envelope.
Frequently Asked Questions
Can I mail my 1040 to the IRS office in my city?
No. Local IRS offices do not process individual tax returns. You must mail to the address for your state listed in IRS Publication 579. Using a local office address will delay your return by weeks as it is rerouted to the correct processing center.
What if I mail my return to the wrong address?
The post office or IRS will eventually forward it to the correct location, but this adds two to four weeks to processing time. If you realize the mistake before mailing, open the envelope and use the correct address instead. If you have already mailed it, note the date and keep your receipt in case you need to prove you filed on time.
Do I need to use certified mail?
Certified mail is optional but recommended. It costs a few dollars and gives you a receipt showing the date mailed and tracking number. This proof is valuable if your return is lost or if the IRS later questions when you filed. Regular mail is acceptable, but you have no proof of delivery.
Can I mail my return to a different state if I moved during the year?
Mail to the address for the state where you lived on December 31 of the tax year you are filing. This is the state that determines your residency for tax purposes. If you moved after December 31, use the address for your prior state of residence.
How long does it take the IRS to process a mailed return?
The IRS typically processes mailed returns within 21 days of receipt, though this varies by volume and time of year. Processing is slower during peak season (February through April). If you file electronically, processing is usually much faster — often within 24 hours for refunds sent by direct deposit.
