The IRS accepts payment by check, electronic transfer, credit or debit card, and installment agreement

You can pay the IRS through several channels depending on what you owe and how quickly you need to send money. The most common methods are mailing a check, paying online through IRS.gov, using an Electronic Federal Tax Payment System (EFTPS) account, or setting up a payment plan if you cannot pay in full. Each method has different processing times, fees, and requirements.

The method you choose affects when the IRS records your payment and whether penalties and interest continue to accrue. Payments made by mail take longer to reach the IRS than electronic payments, which can matter if you are close to a important date. If you owe more than you can pay at once, a payment plan stops some penalties from growing while you pay over time.

Key Takeaways

  • Online payment through IRS.gov, EFTPS, or an IRS-approved payment processor is the fastest way to send money, with confirmation within hours.
  • Mailed checks must arrive by the important date to count as on-time; the IRS counts the postmark date, not the date they open the envelope.
  • Credit and debit card payments through an IRS-approved processor charge a convenience fee of roughly 2 percent, added to your bill.
  • A payment plan (installment agreement) lets you pay in monthly chunks and stops some penalties from growing, though interest still accrues.
  • The payment method you use does not change your tax liability or the amount you owe — only when and how the money reaches the IRS.

Paying by check or money order through the mail

A mailed check is the slowest method but requires no fees or online account. Write your name, address, phone number, and tax identification number on the check. On the memo line, write the tax year and form type — for example, "2023 Form 1040" or "2024 Estimated Tax." Mail the check with a payment voucher, which you can print from IRS.gov or request by phone.

The IRS counts the postmark date as your payment date, not the date they receive and process the check. This means a check postmarked by the important date counts as on-time even if it arrives weeks later. However, if you mail it close to the important date and it arrives after the postmark date passes, you will owe penalties and interest. Money orders follow the same rules as checks and can be mailed the same way.

Mail payments to the address shown on your tax notice or on the IRS website for your state. Using the wrong address delays processing. The IRS does not accept cash by mail.

Paying online through IRS.gov or an approved payment processor

The IRS website (IRS.gov) offers a free online payment tool that processes your payment within hours. You enter your tax identification number, the amount owed, and your bank account information. The system confirms your payment when ready and gives you a confirmation number. This method is free and the fastest way to pay if you have a bank account.

If you prefer to use a credit or debit card, you must go through an IRS-approved payment processor — the IRS does not accept cards directly. The three approved processors are Paypal, Stripe, and Worldpay. Each charges a convenience fee (roughly 2 percent of the amount paid) that the processor adds to your bill. You pay the processor's fee in addition to what you owe the IRS. The fee varies slightly by processor and payment method.

Online payments are recorded on the same day you submit them. If you pay after business hours, the system time-stamps your payment for the next business day. Paying online before midnight on the important date date counts as on-time.

Setting up an Electronic Federal Tax Payment System (EFTPS) account

EFTPS is a free system run by the U.S. Department of the Treasury that lets you schedule tax payments in advance. You enroll once, provide your bank account details, and then schedule payments whenever you need to. Payments can be made up to 120 days in advance. EFTPS is useful if you make estimated tax payments throughout the year or want to automate payments on a set schedule.

To enroll, visit EFTPS.gov and provide your tax identification number, bank account information, and contact details. The IRS mails an enrollment confirmation within two weeks. Once enrolled, you can log in and schedule payments online or by phone. Payments made through EFTPS are free and process within one business day.

EFTPS is separate from the IRS payment tool on IRS.gov, though both are free. Some people use EFTPS for regular estimated payments and the IRS online tool for one-time payments. Both methods work equally well; the choice depends on whether you want to schedule payments in advance.

Payment plans and installment agreements

If you cannot pay your full tax bill at once, you can set up a payment plan (called an installment agreement) to pay in monthly installments. The IRS offers short-term plans (120 days or less) and long-term plans (more than 120 days). A short-term plan has no setup fee. A long-term plan charges a setup fee that ranges from roughly $31 to $225 depending on how you set it up and your income level.

While you are on a payment plan, interest continues to accrue on the unpaid balance, but some penalties stop growing. The failure-to-pay penalty (0.5 percent per month) is reduced to 0.25 percent per month if you have an installment agreement in place. You can set up a plan online through IRS.gov, by phone, or by mail. Online setup is the fastest and has the lowest fee.

Monthly payments are calculated based on how much you owe and how long you want to take to pay it off. The longer the plan, the smaller each monthly payment but the more interest you pay overall. You must stay current on all future tax returns and payments while on a plan, or the agreement can be terminated.

Wire transfers and other electronic methods

The IRS does not accept wire transfers directly. However, some payment processors and banks offer wire transfer options that route the money to the IRS on your behalf. These are less common than the methods listed above and typically charge higher fees. Check with your bank or an IRS-approved processor to see if wire transfer is an option for your situation.

The IRS also does not accept payments through PayPal, Venmo, or other peer-to-peer payment apps directly. If you want to pay by card through PayPal, you must use one of the three IRS-approved processors (Paypal, Stripe, or Worldpay) that are listed on IRS.gov, not the PayPal app itself. The distinction matters because the approved processors are set up to route your payment correctly and provide the IRS with the information they need.

Processing times and confirmation

Online payments through IRS.gov or an approved processor are recorded the same day (or the next business day if submitted after hours). You receive a confirmation number when ready. Mailed checks are recorded when the IRS opens and processes them, which can take two to four weeks depending on mail volume. EFTPS payments process within one business day.

After you pay, check your account on IRS.gov using the "Where's My Refund?" tool or "What You Owe" tool to confirm the payment was received and applied to your account. It can take up to 24 hours for an online payment to show in your account, and up to two weeks for a mailed check. If your payment does not appear after the expected time, contact the IRS at 1-800-829-1040.

Keep your confirmation number or receipt for your records. If you pay by mail, keep a copy of the cancelled check or money order receipt. These documents prove you paid and when, which matters if there is ever a dispute about whether the IRS received your payment.

Frequently Asked Questions

Does it matter which payment method I use if I owe the same amount?

The payment method does not change how much you owe or the interest and penalties that accrue. It only affects when the IRS records your payment and whether you pay a convenience fee. Online payment is faster and free (unless you use a card), while mailed checks are slower but also free. A payment plan changes the penalty rate but not the total interest you pay.

What happens if I mail a check but it arrives after the important date?

The postmark date is what counts, not the arrival date. If your check is postmarked by the important date, it counts as on-time even if it arrives weeks later. If the postmark is after the important date, you owe failure-to-pay penalties and interest from the original important date date, even though you paid as soon as you could.

Can I pay the IRS with a credit card without a convenience fee?

No. The IRS does not accept credit cards directly, and all three approved processors charge a convenience fee (roughly 2 percent). If you want to avoid the fee, pay by check, bank transfer through IRS.gov, or EFTPS. These methods are free.

If I set up a payment plan, do I still owe interest?

Yes. Interest accrues on any unpaid balance regardless of whether you have a payment plan. A payment plan reduces the failure-to-pay penalty from 0.5 percent to 0.25 percent per month, but interest (currently around 8 percent per year, though it changes quarterly) continues to grow on what you still owe.

How do I know if my online payment went through?

You receive a confirmation number when ready after submitting an online payment. Write it down or take a screenshot. Check your account on IRS.gov within 24 hours to see the payment recorded. If you do not see it after two business days, call 1-800-829-1040 with your confirmation number.
