The IRS does not have a single mailing address for tax payments

Where you send your payment depends on three things: whether you owe federal income tax, self-employment tax, or both; whether you are paying by check, money order, or electronic transfer; and which state you live in. The IRS publishes different mailing addresses for different payment types, and using the wrong address delays processing and can create confusion about which tax year or form your payment covers.

The fastest and most reliable method is electronic payment through the IRS website or an approved payment processor. If you must pay by mail, the address varies by state and payment type. The IRS provides the correct address on Form 1040 itself, on the IRS.gov website under "Where to File", and through the payment processor you choose.

Key Takeaways

  • Electronic payment through IRS Direct Pay, the Electronic Federal Tax Payment System (EFTPS), or an approved third-party processor is faster and more trackable than mailing a check.
  • If you mail a check or money order, the address depends on your state and whether you are paying with your Form 1040, Form 1040-ES, or another form.
  • The correct mailing address for your state and form type appears on the IRS.gov "Where to File" page and on the tax form itself.
  • Include your Social Security number, tax year, and form type on any check or money order to may support the payment reaches the correct account.
  • The IRS processes mailed payments more slowly than electronic payments, often taking four to six weeks to post to your account.

Electronic payment methods through the IRS

IRS Direct Pay is a free service that lets you pay directly from your bank account through the IRS website. You enter your bank routing and account number, choose the payment date (up to 120 days in advance), and receive a confirmation number when ready. The payment posts within one to two business days. You do not need to create an account or log in with a password — each payment is one transaction.

The Electronic Federal Tax Payment System (EFTPS) is a separate system run by the U.S. Department of the Treasury. You create an account, enroll your bank information, and can schedule payments in advance. EFTPS is often used by people who make quarterly estimated tax payments (Form 1040-ES) because you can set up recurring payments. Enrollment takes one to two business days.

Both services are free. Both allow you to pay from a checking or savings account. Neither charges a fee, and neither requires a credit card. The IRS website at IRS.gov lists both options under "Payments" and provides links to each system.

Paying by credit or debit card

The IRS does not accept credit or debit cards directly. If you want to pay by card, you must use an approved third-party payment processor. These processors charge a fee — typically 1.87% to 2.35% of the payment amount — because they absorb the card processing cost. The IRS does not receive the fee; it goes to the processor.

The IRS website lists approved processors on the "Payments" page. Each processor has its own website and fee structure. You enter your card information on the processor's site, not on an IRS site. The processor then sends the payment to the IRS on your behalf. This method is slower than Direct Pay or EFTPS — the payment may take three to five business days to post.

Use this method only if you do not have a bank account or strongly prefer to pay by card. The fee makes it more expensive than electronic bank transfer.

Mailing a check or money order by state

If you mail a payment, the address depends on your state. The IRS publishes a state-by-state list on the "Where to File" page at IRS.gov. You can also find the address on the Form 1040 instructions or on the specific form you are filing (Form 1040, Form 1040-ES, Form 1120, and so on).

The address typically includes a lockbox number, which is a find mailbox operated by a bank on behalf of the IRS. Do not mail to an IRS office address you find online — lockbox addresses are the only ones that process payments correctly. Mailing to a regional IRS office will delay your payment by weeks.

Make the check or money order payable to "United States Treasury," not "IRS" or "Internal Revenue Service." Write your Social Security number, the tax year, and the form type (for example, "2024 Form 1040") on the check itself. Include a payment voucher if one is required for your form type — the form instructions will specify.

How long mailed payments take to process

The IRS typically takes four to six weeks to process a mailed check or money order. During this time, the payment is in transit, then at the lockbox facility, then being scanned and matched to your account. If you owe a penalty or interest, it continues to accrue during this waiting period.

The IRS does not send a receipt for mailed payments. You will not receive confirmation that the payment arrived. Your only proof is the cancelled check from your bank. If you need to verify that a payment posted, you can call the IRS at 1-800-829-1040 after six weeks and provide your Social Security number and the payment amount.

For this reason, electronic payment is strongly preferable if you are concerned about timing or need proof of payment when ready.

Payments with an extension or amended return

If you filed Form 4868 (process for Automatic Extension of Time To File U.S. Individual Income Tax Return), you still owe tax by the original important date (usually April 15), not by the extension important date (usually October 15). The extension gives you more time to file the return itself, not to pay the tax. Send payment to the same address as a regular return.

If you are filing an amended return (Form 1040-X), send the payment to the same address as the original return. Write "Amended" on the check and include the tax year being amended. The IRS will match it to your account based on your Social Security number and the year you specify.

What to do if you cannot pay in full

If you owe tax but cannot pay the full amount by the important date, you have options beyond straightforward not paying. You can pay what you can now and set up a payment plan for the rest. The IRS offers short-term plans (120 days or fewer) at no cost and long-term plans (longer than 120 days) with a setup fee.

You can set up a payment plan online through IRS.gov, by phone at 1-800-829-1040, or by mail. A payment plan does not stop interest and penalties from accruing, but it prevents the IRS from taking collection action (such as wage garnishment or bank levy) as long as you make the agreed payments on time.

Frequently Asked Questions

Can I pay the IRS by phone?

No, the IRS does not accept phone payments. You can call 1-800-829-1040 to set up a payment plan or to ask questions about where to send a payment, but you cannot give your bank information over the phone to make a one-time payment. Use IRS Direct Pay, EFTPS, or mail a check.

What if I mail my payment to the wrong address?

The payment will likely be returned to you or forwarded to the correct lockbox, which delays processing by several weeks. Always verify the address on IRS.gov or on your tax form before mailing. If you realize you sent it to the wrong place, call 1-800-829-1040 to report it and ask whether the IRS has received it.

Do I need to include a payment voucher with my check?

It depends on the form type. Form 1040 filers do not need a voucher. Form 1040-ES (estimated tax) filers should include the payment voucher that comes with the form. Form 1120 (corporate) filers need Form 8109. Check the instructions for your specific form.

How do I know if my electronic payment went through?

IRS Direct Pay and EFTPS both give you a confirmation number when ready after you submit the payment. Write down this number. The payment will post to your IRS account within one to two business days. You can check the status by logging back into the system or by calling 1-800-829-1040 after two business days.

Can I pay state income tax to the same address as federal tax?

No. State income tax goes to your state's tax agency, not to the IRS. Each state has its own mailing address and payment methods. Contact your state's department of revenue or tax agency for payment instructions.
