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

The IRS does not have a single mailing address for all payments. The address where you send your check or money order depends on where you live and what type of payment you are making. The correct address is always printed on the notice or bill the IRS sent you — that is the safest place to look first.

If you have lost the notice, the IRS publishes a list of payment addresses by state and payment type on its website. Using the wrong address delays processing and may result in your payment being credited to the wrong account or returned to you.

Key Takeaways

  • The mailing address for your IRS payment is printed on the tax notice or bill you received from the IRS.
  • Different states and different types of payments (income tax, estimated tax, amended returns) have different mailing addresses.
  • The IRS publishes a complete list of payment addresses by state on its website under "Where to File" for paper returns.
  • Always include your name, address, Social Security number, and tax year on your check or money order.
  • Mailing a payment takes longer to process than paying online or by phone, so mail early if you are near a deadline.

How to find the correct mailing address for your state

Go to the IRS website and search for "Where to File" or "IRS mailing addresses." The IRS maintains a table organized by state that shows the mailing address for each type of payment: individual income tax returns, business returns, estimated tax payments, and amended returns.

If you received a bill or notice from the IRS (such as a CP14 or CP501 notice), the correct mailing address for that specific payment is printed on the notice itself. Use that address rather than a general state address, because the IRS may route payments for bills to a different processing center than routine tax payments.

Do not use an address from an old return or an address you find on a third-party tax website. The IRS changes mailing addresses periodically, and using an outdated address can cause delays or misrouting.

What information to include with your mailed payment

Write a check or obtain a money order payable to "United States Treasury." Do not make it payable to the IRS.

On the front of the check or money order, write the following information in the memo line or on the document itself:

  • Your Social Security number or Employer Identification Number
  • The tax year (for example, "2023")
  • The type of return or payment (for example, "1040" or "Estimated Tax")

Include a copy of the bill or notice you received, if you have one. If you are paying for an amended return, include a copy of the amended return itself. Do not send cash. The IRS cannot track cash payments reliably, and you will have no proof of payment if it is lost in the mail.

How long mailed payments take to process

A mailed payment typically takes four to six weeks to appear in your IRS account after the IRS receives it. The time includes mail delivery in both directions, sorting at the IRS processing center, and data entry into the IRS system.

If you are paying close to a tax deadline, mailing is risky. The IRS considers a payment on time only if it is received by the deadline, not if it is postmarked by the deadline. If your payment arrives after the deadline, you may owe penalties and interest even though you mailed it on time.

If you are within two weeks of a deadline, pay online or by phone instead. The IRS accepts online payments the same day you submit them, and phone payments are processed within one business day.

Mailing a payment for an IRS bill or notice

If the IRS sent you a bill (such as a notice of tax due, a CP14, or a CP501), the bill itself contains the mailing address for that payment. This address may be different from the address for a routine tax return filed for the same year.

Include the notice number and the amount due when you mail your payment. If you are paying only part of what you owe, write "partial payment" on the check and include a note explaining which tax year and which notice the payment covers.

The IRS will apply partial payments to the oldest tax year first, unless you specify otherwise in writing. If you want the payment applied to a different year, include a letter with your check stating which tax year should receive the payment.

Alternatives to mailing your payment

The IRS offers faster payment methods that do not require mailing. You can pay online through IRS.gov using a debit card, credit card, or electronic bank transfer. Online payments are processed the same day.

You can also pay by phone by calling the IRS at the number listed on your bill or notice. Phone payments are processed within one business day and you receive a confirmation number immediately.

If you owe a large amount and want to set up a payment plan, you can request an installment agreement online or by phone. An installment agreement lets you pay over time rather than in one lump sum, though interest and penalties continue to accrue.

What to do if you are unsure about the mailing address

Call the IRS at the phone number printed on your bill or notice. The IRS can confirm the correct mailing address for your specific payment and can also tell you whether your payment has been received if you mailed it more than six weeks ago.

If you do not have a bill or notice, you can call the IRS main line at 1-800-829-1040. Have your Social Security number and tax year ready. The IRS can look up your account and tell you the correct address for the payment you want to make.

Frequently Asked Questions

Can I mail a payment to a local IRS office?

No. Local IRS offices do not process mailed payments. You must use the mailing address for your state that the IRS publishes. Sending a payment to a local office will delay processing and may result in the payment being returned or misapplied to your account.

What if I mail my payment and it gets lost?

If your payment does not appear in your IRS account within eight weeks of mailing, contact the IRS. Have your check number, the amount, and the date you mailed it ready. The IRS can search for the payment and, if it was lost, help you submit a replacement payment without penalty.

Do I need to send my payment in a specific type of envelope?

No. Use a standard envelope and regular first-class mail. Do not use certified mail or require a signature — the IRS does not track these features and they add cost. Include your return or bill inside the envelope along with your check.

Can I mail a payment for someone else's tax bill?

Yes, but include a letter with the check stating whose tax account the payment should be applied to, including their Social Security number and tax year. Without this letter, the IRS may not know which account to credit.
