The IRS gives you four ways to pay: online through their website, by phone, by mail, or through your tax professional

The fastest and most common route is IRS Direct Pay, which is free and lets you send money straight from your bank account through irs.gov. You can schedule a payment for a specific date up to 120 days in advance. The money leaves your account within one business day of the date you choose.

If you do not have a bank account or prefer not to use it, you can pay by debit or credit card through a third-party processor (the IRS does not take cards directly). This costs a processing fee — usually 1.87% to 2.35% of the amount you pay, depending on which processor you use. You can also pay by phone at 1-800-829-1040, mail a check, or have a tax professional submit the payment on your behalf.

The key detail: the IRS counts a payment as made on the date you initiate it, not the date the money arrives. If you owe taxes by April 15 and you submit a payment on April 14 through IRS Direct Pay, you are on time even though the money may not clear until April 16.

Key Takeaways

  • IRS Direct Pay through irs.gov is free, takes one business day to process, and lets you schedule payments up to 120 days ahead.
  • Credit and debit card payments cost 1.87% to 2.35% in processing fees but do not require a bank account.
  • Phone payments (1-800-829-1040) and mailed checks are slower but work if you cannot or do not want to pay online.
  • The IRS counts the payment as made on the date you submit it, not the date the money clears your bank.

How to pay through IRS Direct Pay

Go to irs.gov and look for the "Payments" section. You will see a link for IRS Direct Pay. Click it and you will need to enter your Social Security Number or Individual Taxpayer Identification Number, your filing status, and the exact amount you owe.

Next, you enter your bank account information — the routing number and account number from a check, or from your bank's website. The IRS will debit your account on the date you choose. You can pick any date from today through 120 days out. The system will show you a confirmation number when ready; save this or print it.

There is no fee. The money typically leaves your account within one business day of your chosen date. If you need to cancel or change the date, you can do that up until the day before the payment is scheduled to process.

Paying by debit or credit card

The IRS does not take cards directly. Instead, you use a third-party payment processor that the IRS has approved. The three main ones are Worldpay, Paymetrics, and Global Payments. You can find links to all three on irs.gov under the Payments section.

Each processor charges a fee — usually between 1.87% and 2.35% of the amount you pay. So if you owe $5,000 and pay by card, you will pay an extra $94 to $118 in fees. The processor takes the fee out of what you send, so the IRS receives less than you intended unless you add the fee amount to your payment.

The payment processes when ready, and you get a confirmation number right away. The money typically reaches the IRS within one to two business days.

Paying by phone

Call the IRS at 1-800-829-1040. Have your Social Security Number, filing status, and the amount you owe ready. A representative will take your bank account information over the phone and process the payment. There is no fee.

Phone lines are busiest in the morning and during tax season (January through April). You may wait on hold. The payment will process within one business day of the date you authorize it.

Paying by mail

Write a check or money order payable to "United States Treasury." On the front of the check, write your Social Security Number, the tax year, and the form type (1040, 1120, 1065, and so on). Include a payment voucher — you can read Form 1040-ES (for individuals) or the appropriate form for your business type from irs.gov.

Mail the check and voucher to the address listed in your tax notice or on the IRS website for your state. Processing takes two to four weeks from the date the IRS receives it. The IRS counts the payment as made on the postmark date, so mail it early enough that it arrives before your important date.

Keep a copy of the front and back of your check for your records. If the check is lost in the mail, the IRS will not know you sent it unless you have proof.

Paying through a tax professional

If you use a CPA, tax attorney, or enrolled agent to prepare your return, they can submit your payment on your behalf. They typically use IRS Direct Pay or a payment processor and charge you a fee for handling it — usually $25 to $75 depending on the firm.

This is useful if you want someone else to manage the timing or if you are making a large payment and want a professional to confirm the details. The payment still counts as made on the date your professional submits it, not the date you authorize them.

What happens after you pay

The IRS will send you a notice showing the payment received and your account balance. This can take two to four weeks. In the meantime, you can check the status of your payment on irs.gov using the "Where's My Payment?" tool — though this tool is usually for refunds, not payments you send in.

If you overpay, the IRS will either refund the difference or explore it to a future tax year, depending on what you request. If you underpay, the IRS will charge interest and penalties on the unpaid amount starting the day after the important date.

Frequently Asked Questions

What if I cannot pay the full amount by the important date?

You can pay what you can and set up a payment plan for the rest. The IRS offers short-term plans (120 days or less) at no cost and long-term plans (longer than 120 days) for a setup fee. Interest and penalties will accrue on the unpaid balance, but a payment plan stops the failure-to-pay penalty from growing as quickly.

Can I pay someone else's tax bill?

Yes. You can pay through IRS Direct Pay or by mail using the taxpayer's Social Security Number and tax year. The IRS will credit the payment to their account. By phone or card, you will need to provide their information, and the processor may ask for authorization.

Is there a limit to how much I can pay at once?

IRS Direct Pay has no stated limit, though some banks may flag very large transfers. Card processors may have limits depending on the processor and your card issuer. If you are paying a very large amount, call the IRS first to confirm the best method.

What if I make a mistake on my payment?

If you sent too much, the IRS will refund or credit the overpayment. If you sent too little, you owe the difference plus interest and penalties. If you sent it to the wrong account or with the wrong taxpayer information, contact the IRS when ready at 1-800-829-1040 to correct it.

Do I get a receipt when I pay?

Yes. IRS Direct Pay and card payments give you a confirmation number when ready. Mailed checks do not produce a receipt from the IRS, so keep a copy of your cancelled check. Phone payments give you a confirmation number the representative will read to you — write it down.
