Mail your tax payment to the IRS service center that covers your state

The address you use depends on which state you live in and whether you are paying with a check or money order. The IRS maintains separate mailing addresses for different regions. Using the wrong address delays processing and can create confusion about whether your payment arrived.

Do not mail a payment to an IRS office building you can see or find online. The IRS does not process payments at local offices. All mailed payments go to one of ten regional service centers designed to handle mail volume.

The fastest way to find your correct address is to look at the tax form instructions for the return you are filing — Form 1040, Form 1120, Form 1065, or whichever applies to you. The instructions include a table that matches your state to a mailing address. You can also find the addresses on the IRS website under "Where to File" for your return type.

Key Takeaways

  • The correct mailing address depends on your state and the type of return you are filing, not on which IRS office is nearest you.
  • The address you need is printed in the instructions that come with your tax form, in a table labeled by state.
  • Always mail a check or money order with your return, never cash, and write your Social Security number and tax year on the check itself.
  • Mailed payments typically take two to three weeks to post to your account after the IRS receives them.
  • If you need proof that your payment arrived, send it by certified mail with return receipt requested.

How to find the mailing address for your state and return type

Start with the form instructions. If you are filing Form 1040 (individual income tax), open the Form 1040 instructions PDF from the IRS website or the version that came with your tax software. Scroll to the section titled "Where to File" or "Mailing Address." You will see a table with state abbreviations in one column and mailing addresses in another.

Find your state in that table and copy the full address exactly as printed. Do not abbreviate street names or change the zip code. The IRS sorts mail by zip code, and even small changes can send your payment to the wrong processing center.

If you are filing a different return type — Form 1120 for a corporation, Form 1065 for a partnership, Form 1040-ES for estimated tax payments — that form's instructions contain its own "Where to File" table. The addresses may differ from the individual return addresses.

What to include with your mailed payment

Mail a check or money order only. Do not send cash. Make the check payable to "United States Treasury" and write your Social Security number, the tax year, and the form type on the check itself. For example: "2024 Form 1040" and your SSN in the memo line.

Include a payment voucher if one applies to your return type. If you are paying with your 1040, you do not need a separate voucher — the return itself serves as your payment record. If you are making an estimated tax payment (Form 1040-ES), include the payment voucher that came with the form. If you are paying a balance due on a prior year return, include a copy of that return or a statement showing the year and amount owed.

Do not staple the check to your return or voucher. Paperclip them together or simply place them in the envelope in order. The IRS processes checks and returns through different machines, and staples jam the equipment.

Timing: how long mailed payments take to process

The IRS typically receives mail within five to seven business days of when you drop it in a mailbox. Once received at the service center, the payment is scanned and posted to your account within two to three weeks. The total time from mailing to posting is usually three to four weeks.

This delay matters if you owe a balance due. Interest and penalties continue to accrue until the payment posts, not when you mail it. If you are close to a deadline or want the payment to post by a specific date, use electronic payment instead of mail.

If you are filing your return and paying at the same time, mail both together in the same envelope. The return and payment will be processed as a unit.

Getting proof that your payment arrived

The IRS does not send a receipt when a mailed payment arrives. If you need documentation that your check was received, send it by certified mail with return receipt requested. The post office will give you a receipt showing the delivery date, and you keep a copy for your records.

You can also track your payment online after it posts. Once the IRS processes your payment, it will appear in your IRS account under "Payment History" on IRS.gov. You can log in with your Social Security number or Individual Taxpayer Identification Number to view the date the payment posted and the amount.

If your payment does not appear in your account within four to five weeks of mailing, contact the IRS at 800-829-1040 to report it. Have your check number, the amount, and the date you mailed it ready.

When to use electronic payment instead of mail

If your payment deadline is within three weeks, do not mail it. Electronic payment methods post within one business day and are safer than mail. The IRS offers several options: Direct Pay (free, from your bank account), Electronic Federal Tax Payment System (EFTPS, also free), and credit or debit card payment (with a fee charged by a third-party processor).

Electronic payment also eliminates the risk of a lost check. Mail can be delayed by weather, postal service backlogs, or sorting errors. If you are paying a large amount or need certainty that the payment will post by a specific date, electronic payment is more reliable.

You can still mail your return while paying electronically. File your return by mail and make your payment through Direct Pay or EFTPS on the same day or a few days before. The return and payment will be matched by your Social Security number.

Addresses for the ten IRS service centers

The IRS maintains ten regional service centers. Your state is assigned to one of them based on your mailing address. Rather than listing all ten addresses here — which would duplicate the official table in your form instructions — use the "Where to File" table in your tax form's instructions or search "IRS where to file" on the IRS website.

The official table is updated each year and reflects any address changes. Printing addresses from a website or article risks using outdated information. The form instructions you are holding or the PDF you downloaded are always current for that tax year.

Frequently Asked Questions

Can I mail my payment to a local IRS office?

No. Local IRS offices do not process mailed payments. All payments must go to the regional service center assigned to your state. Sending a payment to a local office will delay it and may cause it to be returned to you.

What if I mail my payment but forget to include my Social Security number on the check?

The IRS will still process the payment, but it may take longer to match it to your account. Write your SSN on the check itself, not just on the return. If you realize the mistake after mailing, contact the IRS at 800-829-1040 with your check number and amount so they can note it in their system.

Do I need to mail my payment with my return, or can I send them separately?

You can send them together or separately. If you send them together, use the mailing address from your return's instructions. If you send the payment alone, use the payment mailing address (which may differ slightly). Both will be matched to your account by your Social Security number.

What happens if I mail a check but it gets lost in the mail?

If your payment does not appear in your IRS account within four to five weeks, the IRS will not have a record of it. Contact the IRS at 800-829-1040 with your check number, amount, and mailing date. They can research whether it was received. If it was not, you will need to stop payment on the original check and send a new payment electronically or by mail.

Is mailing a payment slower than paying online?

Yes. Mailed payments take three to four weeks to post, while electronic payments post within one business day. If you have a deadline or want the payment to post quickly, use Direct Pay, EFTPS, or a credit card payment instead of mail.
