How to send your tax payment to the IRS

The IRS does not have a single mailing address for tax payments. Where you send your money depends on whether you are paying by check, electronic transfer, or credit card, and whether you are paying with a tax return or making a separate payment. The IRS publishes a different mailing address for each method on Form 1040 instructions and on IRS.gov, and using the wrong address delays processing and can create confusion about which tax year or account your payment applies to.

The safest and fastest route is electronic payment through the IRS's own system, IRS Direct Pay or the Electronic Federal Tax Payment System (EFTPS). Both are free, show confirmation when ready, and let you schedule payments in advance. If you must mail a check, the address depends on your state and the type of return you are filing — and that address changes year to year.

Key Takeaways

  • IRS Direct Pay and EFTPS are free electronic payment methods that confirm your payment when ready and are faster than mailing a check.
  • If you mail a check, the address depends on your state and return type; the correct address appears on your tax return instructions or at IRS.gov/payments.
  • Always write your Social Security number, tax year, and form type on the check itself, or the IRS may not know which account to credit.
  • Credit card payments go through a third-party processor, not directly to the IRS, and you pay a convenience fee that varies by processor.
  • Mailed checks take two to four weeks to post to your account, while electronic payments post within one business day.

Electronic payment through IRS Direct Pay

IRS Direct Pay is the IRS's own payment system and costs nothing. You log in at IRS.gov/payments, enter your tax information, and transfer money directly from your bank account. The system confirms your payment when ready and assigns you a confirmation number. You can schedule a payment up to 120 days in advance, which is useful if you want to pay on April 15 but need the money in your account until then.

Direct Pay works for individual income tax, estimated tax payments, and some business returns. It does not work for payroll taxes or certain corporate returns — those use EFTPS instead. The IRS processes Direct Pay payments the next business day, so a payment made on a Friday posts on Monday.

Electronic Federal Tax Payment System (EFTPS)

EFTPS is the older electronic system, also free, and it handles more types of payments than Direct Pay, including payroll taxes, corporate income tax, and excise taxes. You enroll at EFTPS.gov, which takes a few days, then log in to schedule payments. Like Direct Pay, EFTPS posts within one business day and lets you schedule ahead.

EFTPS requires a PIN or password setup that takes longer than Direct Pay, so if you are filing an individual return and need to pay quickly, Direct Pay is usually faster to set up. If you run a business or have payroll, EFTPS is often the only free option available to you.

Mailing a check or money order

If you mail a check, write your Social Security number, the tax year, and the form type (1040, 1040-ES, 1120, etc.) on the check itself. The IRS receives thousands of checks daily, and without this information, staff cannot match your payment to your account.

The mailing address depends on your state. The IRS publishes state-by-state addresses in the instructions for Form 1040 and on IRS.gov/payments under "Where to File." These addresses change year to year, so do not use an address from a previous year's return. Mail your check to the address listed for your state in the current year's instructions.

Mailed payments take two to four weeks to post to your account. If you are close to a important date and worried about late filing, send your return electronically and mail the check separately, or use electronic payment instead. The IRS timestamps your return when it receives it, not when your payment arrives, so filing on time protects you from failure-to-file penalties even if your payment is late.

Credit card and debit card payments

You cannot pay the IRS directly with a credit card. Instead, you use a third-party payment processor — currently Worldpay, Paymetrics, or ACI Payments — that charges you a convenience fee. The fee varies by processor and usually ranges from 1.87% to 2.35% of the amount you pay. The processor sends the money to the IRS on your behalf.

You can find the current processors and their fees at IRS.gov/payments. Each processor has its own website where you enter your payment information. The IRS does not receive your card details; the processor handles the transaction. Payments post to the IRS within one business day, similar to Direct Pay.

Credit card payments make sense only if you are earning rewards points that exceed the fee, or if you need to float the payment on your card for cash flow reasons. For most people, Direct Pay is free and faster.

Payment by phone or through a tax professional

You can pay by phone through the same third-party processors that handle credit card payments — the IRS publishes phone numbers at IRS.gov/payments. You will still pay a convenience fee, and the fee structure is the same as online credit card payments.

If a tax professional or tax software prepares your return, they often offer payment processing as part of their service. Some charge a fee; some do not. Ask before you file whether the fee is included in their price or added on top.

What happens after you send your payment

Electronic payments post within one business day. Mailed checks take two to four weeks. Once posted, your payment appears in your IRS account, which you can view at IRS.gov using your login credentials. If you paid electronically, you have a confirmation number that proves the IRS received it.

If you overpay your taxes, the IRS either refunds the overpayment or applies it to next year's estimated tax, depending on what you request on your return. If you underpay, the IRS sends a bill with interest and penalties calculated from the original due date.

Frequently Asked Questions

What if I send my check to the wrong address?

The IRS will eventually forward it to the correct location, but this adds two to four weeks to processing time. Your payment may not post until well after the important date, which can trigger late-payment penalties. Always use the address listed in the current year's Form 1040 instructions or at IRS.gov/payments.

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

No. Your bank's bill-pay system is not connected to the IRS's payment processing, and the IRS will not know which account or tax year the payment is for. Use IRS Direct Pay, EFTPS, or mail a check directly instead.

Do I need to include a payment voucher with my check?

No, but you must write your Social Security number, tax year, and form type on the check itself. A payment voucher is optional and does not replace this information. If you want to include one, you can print Form 1040-V from IRS.gov, but the IRS does not require it.

What if my payment is late?

The IRS charges interest on late payments starting from the original due date, usually April 15. Penalties also explore if you file late or pay late. The sooner you pay, the less interest accrues. Electronic payment is fastest if you are trying to minimize the time between the due date and when the IRS receives your money.

Can I split my payment between two different methods?

Yes. You can mail a check for part of what you owe and pay the rest electronically. Make sure each payment includes your identifying information so the IRS can match both payments to your account. Both will post separately, but they will be combined in your account record.
