You can pay the IRS online, by phone, by mail, or through an automatic withdrawal from your bank account

The IRS accepts payments through several channels, and the method you choose depends on how much you owe, how quickly you need to pay, and whether you want a record of the transaction immediately. Online payment through the IRS website is the fastest and most common route for individual taxpayers. If you owe a smaller amount and prefer to mail a check, that works too — but it takes longer to process and you lose the immediate confirmation that your payment arrived.

The IRS does not accept payment in person at local offices. You cannot walk into an IRS building and hand over cash or a check. All payments go through one of the methods below, and each one creates a record that the IRS can match to your account.

Key Takeaways

  • Online payment through IRS.gov is the fastest method and gives you immediate confirmation; you can pay with a debit card, credit card, or bank account transfer.
  • If you mail a check, write your Social Security number and tax year on the back and send it to the address listed on your tax notice, not to a general IRS office.
  • Paying by phone requires calling a payment processor, not the IRS directly, and you will need your bank account or card information ready.
  • Automatic bank withdrawals (direct debit) are free and can be scheduled for a specific date, which is useful if you are on a payment plan.
  • The IRS applies payments to the oldest tax year first, then to penalties and interest, so paying anything reduces what you owe even if you cannot pay in full.

Paying online through IRS.gov

Go to IRS.gov and look for the payment section — it is labeled "Pay Now" or "Make a Payment" depending on the page. You will be directed to the IRS's official payment processor, which handles the transaction securely. You do not enter your payment information directly on the IRS website itself; the processor collects it and sends the confirmation back to the IRS.

You can pay with a debit card, credit card, or by transferring money directly from your bank account. Credit card and debit card payments usually include a convenience fee (typically 1.87% to 2.35% of the amount you pay), which the processor charges, not the IRS. Bank account transfers are free. You will see the fee amount before you confirm the payment, so you can decide whether to proceed or choose a different method.

After you complete the payment online, you receive a confirmation number immediately. Write this number down or save the confirmation email — it is your proof of payment. The IRS typically processes online payments within one business day, though it can take up to three days depending on your bank.

Paying by mail with a check or money order

If you are paying by mail, use the address printed on your tax notice or bill, not a general IRS office address. The notice will say "Make checks payable to United States Treasury." On the back of the check or money order, write your Social Security number, the tax year you are paying for, and the form number (usually 1040 for individual income tax). This information helps the IRS match your payment to your account.

Mail payments take 7 to 14 days to arrive and process, depending on which IRS processing center handles your state. During this time, interest and penalties continue to accrue on any unpaid balance. If you are close to a deadline — such as before an enforcement action or wage garnishment — mailing a check is risky because the IRS may not receive it in time.

Keep a copy of the front and back of your check or a photo of your money order receipt. If the IRS later claims they did not receive your payment, you will have proof of when you sent it and how much you paid.

Paying by phone through an IRS payment processor

You can call a payment processor to pay by phone. The IRS website lists the current processors and their phone numbers. When you call, have your Social Security number, the amount you want to pay, and your bank account or card information ready. The processor will guide you through the payment and give you a confirmation number at the end of the call.

Phone payments are processed the same way as online payments — the processor collects your information and sends it to the IRS. There is no fee for paying by bank account transfer over the phone, but credit and debit card payments include the same convenience fee as online payments. Processing takes one to three business days.

Setting up automatic payments or a payment plan

If you cannot pay your full tax bill at once, you can set up an automatic monthly payment through the IRS website. This is called a payment agreement or installment plan. You choose the amount and the date each month, and the IRS withdraws it directly from your bank account. This method is free — there is no convenience fee — and it stops interest and penalties from growing as quickly as they would if you made no payment at all.

To set up an automatic payment, you do not need to be on a formal payment plan first. You can simply arrange recurring transfers through your bank or through the IRS website. However, if you owe more than a certain amount (which varies by year), the IRS may require you to enter into a formal agreement. The IRS website has a tool to check whether you may have access to for a short-term extension (up to 180 days) or whether you need a longer payment plan.

How the IRS applies your payment to your account

When you send money to the IRS, they do not let you choose which tax year or which part of your bill it goes toward. Instead, the IRS applies payments in a set order: first to the oldest tax year, then to penalties, then to interest. If you owe taxes from 2021 and 2023, a payment you make today goes to 2021 first.

This matters because penalties and interest keep growing. By paying toward the oldest year first, the IRS reduces the total amount owed faster than if you could direct the payment yourself. However, it also means that if you owe multiple years and can only pay part of what you owe, you will not clear any single year completely — you will reduce all of them a little.

What to do if you cannot pay right now

If you owe the IRS but do not have the money to pay, do not ignore the bill. The IRS will add penalties and interest, and after a certain period they can place a lien on your property, garnish your wages, or seize your bank account. However, you have options before it reaches that point.

You can request a payment plan, ask for a temporary delay (called an extension of time to pay), or claim financial hardship if you truly cannot pay. The IRS website has a tool to set up a payment plan online without calling. If you are in financial hardship, you can contact the IRS directly to discuss your situation, though this process is slower than setting up a plan online.

Frequently Asked Questions

Do I have to pay a fee to pay the IRS?

No fee applies if you pay by bank account transfer (online, by phone, or through automatic withdrawal). Credit card and debit card payments include a convenience fee of roughly 1.87% to 2.35%, charged by the payment processor, not the IRS. You see the fee before you confirm the payment.

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

Online and phone payments process within one to three business days. Mailed checks take 7 to 14 days to arrive and process. If you are paying to meet a deadline, online or phone payment is safer because you get a confirmation number immediately.

What if I pay more than I owe?

The IRS will hold the overpayment and apply it to any other tax years you owe, or refund it to you. You can request a refund or ask them to apply it to next year's estimated tax. Contact the IRS or check your account online to see what they did with the overpayment.

Can I pay the IRS with a credit card at a store or bank?

No. You can only pay the IRS through the methods listed on their website — online, by phone, by mail, or through automatic bank withdrawal. You cannot pay at a retail location or walk into a bank and pay there.

What happens if I miss a payment on my payment plan?

If you miss a payment, the IRS may cancel your agreement and demand the full remaining balance. Contact the IRS as soon as you know you will miss a payment — they may allow you to catch up or modify the plan rather than cancel it.
