Send your IRS payment to the address printed on your tax notice or bill

The IRS does not have a single national mailing address for tax payments. Instead, the address where you send your check or money order depends on which IRS service center handles your region and what type of payment you are making. The safest approach is to use the address printed on the notice or bill you received — the IRS includes the correct mailing address on every document they send you.

If you have lost the notice or need to find the address yourself, the IRS publishes a list of regional payment addresses on their website organized by state. The address you use matters because mail sent to the wrong location will be delayed or may not reach the right department, which can result in your payment being recorded late.

Key Takeaways

  • The address printed on your IRS notice or bill is always the correct mailing address for your payment.
  • Different IRS service centers handle different regions, so the address varies by state and sometimes by county.
  • Mailing a check or money order typically takes 7 to 14 days to clear, so send it well before your payment deadline.
  • Electronic payment methods like IRS Direct Pay or the Electronic Federal Tax Payment System (EFTPS) deliver payment the same day and do not require a mailing address.

How to find the correct mailing address for your region

The IRS maintains a state-by-state list of payment addresses on IRS.gov under "Where to File." Search for your state, and the page will show the mailing address for checks and money orders. This list is updated regularly, so verify the address before you mail your payment rather than using an old bill or letter.

If you received a notice from the IRS — such as a bill for taxes owed, a notice of deficiency, or a demand for payment — the correct mailing address is printed on that document. Using the address on your notice is the most reliable method because it routes your payment directly to the department that issued the bill.

What information to include with your mailed payment

Write your Social Security number or Employer Identification Number (EIN) on the front of your check or money order. Do not send cash. Include a copy of the bill or notice you received, or write on a separate sheet of paper your name, address, phone number, tax year, and the type of tax you are paying (income tax, self-employment tax, estimated tax, etc.).

Mail your payment in an envelope with a return address so the IRS can contact you if there is a problem. Keep a copy of everything you send for your records. The IRS recommends using certified mail with return receipt if you want proof that your payment arrived, though this is not required.

Timeline for mailed payments to be recorded

A check or money order mailed to the IRS typically takes 7 to 14 days to arrive and be processed. The IRS considers your payment made on the date you mail it, not the date they receive it — but only if you mail it by the deadline. If your deadline is April 15 and you mail your payment on April 14, it counts as timely even if it does not arrive until April 25.

However, if the IRS does not receive your payment within 30 days of the deadline, they may assess a failure-to-pay penalty. To avoid this risk, mail your payment at least two weeks before the deadline. If you are close to the deadline, use an electronic payment method instead.

Electronic payment methods that do not require a mailing address

IRS Direct Pay is a free online tool where you can pay directly from your bank account. The payment is deducted the same day or on a date you choose, and you receive a confirmation number immediately. You do not need to mail anything.

The Electronic Federal Tax Payment System (EFTPS) is another free option run by the U.S. Department of the Treasury. You enroll online, link your bank account, and schedule payments up to 120 days in advance. Payments clear within one business day.

Credit or debit card payments can be made through approved payment processors listed on IRS.gov. The IRS does not process card payments directly; you pay a processing fee (usually 1.87% to 2.35% of the payment amount) to the third-party processor. Payment is recorded the same day.

Electronic methods are faster and more reliable than mailing a check, and they eliminate the risk of your payment getting lost in the mail.

What to do if you are unsure about the address

Call the IRS at 1-800-829-1040 (the main tax line) and provide your Social Security number or EIN. A representative can confirm the correct mailing address for your region and answer questions about your specific bill. Wait times are often long, so call early in the morning or later in the week if possible.

You can also visit an IRS office in person if one is located near you. Search "IRS office locations" on IRS.gov to find the nearest one and check their hours before you go.

Frequently Asked Questions

Does the IRS accept payments at their local office?

Most IRS offices do not accept cash or check payments in person. You must mail your payment or use an electronic method. Call ahead to confirm whether your local office accepts payments before you visit.

What if I mail my payment to the wrong address?

If your payment reaches a different IRS location, it will eventually be forwarded to the correct service center, but this adds 2 to 4 weeks to processing time. Your payment may be recorded late if it misses the deadline. Always verify the address before mailing.

Can I send my payment to an IRS P.O. box?

The IRS does not use P.O. boxes for tax payments. The addresses listed are street addresses for IRS service centers. Use the exact address provided on your notice or on IRS.gov.

Is there a penalty if my mailed payment arrives late?

The IRS considers your payment made on the postmark date, not the arrival date. If you mail it by the deadline, it is on time even if it arrives late. However, if the postmark is after the deadline, penalties and interest will apply.

Should I use certified mail to send my IRS payment?

Certified mail is optional but recommended if you want proof of mailing. Keep the receipt and tracking number for your records. Regular first-class mail is acceptable and will be processed the same way once it arrives.
