Send your payment to the address on your tax notice, or use the IRS payment portal if you're paying online

The place you send an IRS payment depends on what type of payment you're making and whether you're paying by mail or electronically. If the IRS sent you a notice about taxes you owe, that notice includes a payment address specific to your situation. If you're making a payment without a notice, the IRS has a dedicated online system called IRS Direct Pay that handles electronic payments, or you can mail a check to a regional address based on where you live.

The safest approach is to use the payment method the IRS suggests in any notice they sent you. If you don't have a notice and need to pay, the online portal is faster and gives you when ready confirmation. Mailed checks take longer to process and can get lost, so electronic payment is worth the few minutes it takes to set up.

Key Takeaways

  • Always check any IRS notice you received first — it will have the correct mailing address or payment instructions for your specific case.
  • IRS Direct Pay is a free online system where you can pay by bank account or debit card and get a confirmation number when ready.
  • If you mail a check, write your Social Security number or tax ID and the tax year on the check itself, and use the address printed on your notice.
  • Credit card payments go through third-party processors, not directly to the IRS, and you'll pay a processing fee.
  • If you set up a payment plan instead of paying in full, the IRS will tell you where and how to send each installment.

Paying online through IRS Direct Pay

IRS Direct Pay is the fastest way to send money to the IRS if you don't have a specific notice with payment instructions. You go to irs.gov/payments, enter your Social Security number or tax ID, the tax year, and the amount you want to pay, then authorize a transfer from your bank account. The system gives you a confirmation number right away, and you can see the payment status online for up to 120 days.

There is no fee to use Direct Pay — the IRS doesn't charge you anything. You'll need your bank account and routing number, or you can use a debit card. The payment usually reaches the IRS within one business day if you submit it before 8 p.m. Eastern time on a weekday. If you submit it after that or on a weekend, it processes the next business day.

Direct Pay works whether you're paying a balance from a past year or making an estimated tax payment for the current year. You can also set up a payment plan through the same system if you can't pay the full amount at once.

Mailing a check or money order

If you prefer to mail a payment, the address depends on which IRS service center handles your state. The IRS publishes a list of mailing addresses by state on irs.gov, or you can find the correct address on any notice the IRS sent you — that notice will have the right address for your case.

Write your Social Security number or tax ID number on the check or money order itself, along with the tax year you're paying for. For example, if you're paying 2023 taxes, write "2023" on the check. Include a copy of any notice the IRS sent you, or write a brief note saying what year and what type of tax you're paying for. Mail the check to the address on your notice or to the regional service center for your state.

Mailed payments take two to three weeks to process after the IRS receives them. The postmark date counts as your payment date for penalty purposes, so mail it early enough that it arrives before any important date. Keep a copy of the check or the money order receipt for your records.

Paying by credit or debit card

You cannot send a credit card payment directly to the IRS. Instead, you use a third-party payment processor that the IRS has approved. These processors charge a fee — usually between 1.87% and 2.35% of the amount you pay — and that fee is added to your payment. For example, if you pay $1,000 by credit card, you might pay an additional $19 to $24 in processing fees.

The approved processors are listed on irs.gov/payments. You choose the processor, enter your card information on their website, and they send the money to the IRS on your behalf. You'll get a confirmation number from the processor, not directly from the IRS. The payment usually reaches the IRS within one business day.

Credit card payments make sense only if you're earning rewards points that are worth more than the fee, or if you absolutely cannot pay by bank account or debit card. For most people, Direct Pay or a mailed check costs less.

Paying through a payment plan or installment agreement

If you can't pay the full amount at once, you can set up a payment plan (also called an installment agreement) through IRS Direct Pay or by mail. The IRS will tell you where to send each monthly payment as part of the agreement. Some payment plans allow you to pay electronically each month, while others require mailed checks.

Short-term payment plans (120 days or less) have no setup fee. Long-term plans charge a fee that depends on how you set up the payments — electronic payments have a lower fee than mailed payments. The IRS will explain the fees and the payment address when you set up the plan.

What to do if you're unsure about the address

If you have a notice from the IRS, use the address printed on that notice. That address is specific to your case and the type of tax you owe. If you don't have a notice and you're not sure which address to use, call the IRS at 1-800-829-1040 and they will tell you the correct mailing address or direct you to IRS Direct Pay.

You can also check irs.gov/payments, which lists the mailing addresses by state and explains how to use Direct Pay. The website also has a tool to find the service center for your state if you need to mail a payment.

What happens after you send your payment

If you pay online through Direct Pay, you'll see a confirmation number when ready and can track the payment status on the IRS website. If you mail a check, the IRS will process it once it arrives at the service center — this usually takes two to three weeks. You won't get a separate confirmation, but the payment will show up on your IRS account once it's processed.

Keep your confirmation number (if you paid online) or a copy of the cancelled check (if you mailed it) for your records. If you ever need to prove you made the payment, you'll have documentation. If you set up a payment plan, the IRS will send you a notice confirming the agreement and the payment schedule.

Frequently Asked Questions

Can I pay the IRS through my bank's bill pay system?

No. Your bank's bill pay system is not the same as IRS Direct Pay. You must use irs.gov/payments or mail a check to the address on your notice. If you try to pay through your bank's bill pay, the payment may not reach the IRS or may be delayed, and you could be charged a penalty for late payment.

What if I mail my check to the wrong address?

The check may be returned to you or forwarded to the correct service center, which delays processing. To avoid this, always use the address printed on your IRS notice or look up your state's service center address on irs.gov before mailing. If you're not sure, use Direct Pay instead.

Do I need to include a cover letter with my mailed payment?

You don't need a formal letter, but it's helpful to include a note with your check that says what year and what type of tax you're paying for. Include a copy of your notice if you have one. This helps the IRS match your payment to your account quickly.

How long does it take for the IRS to receive my payment?

Online payments through Direct Pay reach the IRS within one business day. Mailed checks take two to three weeks after they arrive at the service center. The postmark date is your payment date for penalty purposes, so mail early if you're close to a important date.

What if I overpay the IRS?

If you pay more than you owe, the IRS will either refund the extra amount or explore it to future taxes you may owe. You can request a refund when you file your next tax return, or you can ask the IRS to explore the overpayment to next year's estimated taxes.
