Send your Form 1040-ES payment to the IRS address that matches your state and payment method

The IRS does not have a single mailing address for all Form 1040-ES payments. Where you send your check or money order depends on which state you live in. The IRS publishes a list of state-specific addresses on the back of Form 1040-ES itself, and also maintains the list on IRS.gov under "Where to File" for estimated tax payments.

If you are mailing a check or money order, you must include the payment voucher (the stub that comes with Form 1040-ES) with your payment. The voucher tells the IRS which quarter the payment covers and links it to your tax account. Without the voucher, the IRS may not know which tax year or quarter your payment is for, and processing will be delayed.

Most taxpayers no longer mail payments. The IRS offers faster, more reliable methods: the Electronic Federal Tax Payment System (EFTPS), the IRS Direct Pay system on IRS.gov, or credit and debit card payments through an IRS-approved payment processor. These methods deliver your payment the same day and provide immediate confirmation.

Key Takeaways

  • Mailed Form 1040-ES payments go to a state-specific IRS address listed on the back of the form or on IRS.gov.
  • Always include the payment voucher (the tear-off stub) when mailing a check or money order so the IRS can match it to your account and tax year.
  • Electronic Federal Tax Payment System (EFTPS) and IRS Direct Pay are free, faster, and provide same-day confirmation without mailing delays.
  • Credit and debit card payments are also accepted through IRS-approved processors, though a processing fee applies.
  • If you mail your payment, allow at least two weeks for the IRS to receive and post it to your account.

How to find the correct mailing address for your state

The back of Form 1040-ES lists mailing addresses by state. Look for your state in the list and use the address shown for "Estimated Tax Payments." Do not use the address for filing your annual return—they are different.

If you do not have the form in front of you, go to IRS.gov and search for "Form 1040-ES" or "Where to File." The IRS website displays the same state-by-state list. Some states have multiple addresses depending on the payment method (mailed versus electronic), so read carefully to match your method to the correct address.

The addresses change occasionally, so do not rely on an old form or a list you saved from a previous year. Always check the current form or the IRS website before mailing.

What to include when mailing a check or money order

Write your check or money order for the full amount of your estimated tax payment. Make it payable to "United States Treasury." Do not make it payable to the IRS or to any other name.

Tear off the payment voucher from Form 1040-ES—this is the stub at the bottom of the form that shows your name, address, Social Security number, the tax year, and the quarter. Attach the voucher to the front of your check or money order. The voucher is how the IRS matches your payment to your tax account.

Place the check, money order, and voucher in an envelope and mail to the address for your state. Use first-class mail or a tracked service so you have proof of mailing. The IRS does not accept payments sent to local IRS offices or to tax preparation companies.

Electronic Federal Tax Payment System (EFTPS)

EFTPS is a free service run by the U.S. Department of the Treasury that lets you pay federal taxes electronically from your bank account. You can schedule payments up to 120 days in advance, and the payment is deducted on the date you choose.

To use EFTPS, you must enroll first. Go to EFTPS.gov, click "Enroll," and provide your Social Security number, date of birth, and mailing address. The IRS will mail you a Personal Identification Number (PIN) within two weeks. Once you receive the PIN, you can log in and make payments.

On the day you want to pay, log into EFTPS, enter the payment amount, select the tax type (Form 1040-ES), and choose the quarter. The payment is processed the same day if you submit it before 8 p.m. Eastern Time on a business day. EFTPS sends you a confirmation number immediately.

IRS Direct Pay on IRS.gov

IRS Direct Pay is a free payment tool on the IRS website that does not require advance enrollment. Go to IRS.gov, search for "IRS Direct Pay," and click the link. You will need your Social Security number, date of birth, mailing address, and bank account information (routing number and account number).

Enter the payment amount, select Form 1040-ES, and choose the quarter. You can pay immediately or schedule a payment for a future date up to 120 days away. The IRS provides a confirmation number on screen and sends a confirmation email. The payment is deducted from your bank account on the date you select.

Direct Pay works with checking and savings accounts. It does not charge a fee. Processing takes one business day, so if you pay on a Friday, the money may not leave your account until Monday.

Credit and debit card payments

The IRS does not accept credit or debit cards directly. Instead, you must use an IRS-approved payment processor. The IRS website lists three approved processors: Authorize.Net, PayPal, and Stripe. Each processor charges a convenience fee (usually 1.87% to 2.35% of the payment amount) that you pay in addition to your tax payment.

Go to IRS.gov, search for "Pay by Card," and click the link to the approved processors. Choose the processor you prefer, enter your payment information, and complete the transaction. You will receive a confirmation number from the processor and a separate confirmation from the IRS.

Credit and debit card payments are processed the same day. The fee is not deductible as a tax payment, so you pay it out of pocket. If you are paying a large estimated tax amount, the fee can be significant, so compare it to the cost of mailing (a stamp) or using a free method like EFTPS or Direct Pay.

Timing and what happens after you pay

If you mail a check or money order, allow at least two weeks for the IRS to receive it and post it to your account. If you mail it close to a quarterly deadline, the payment may not be recorded in time, and you could be charged a penalty for underpayment even though you sent the money. For this reason, mailing is the slowest and riskiest method.

Electronic payments (EFTPS, Direct Pay, or card payments) are posted to your account the same day or the next business day. You receive a confirmation number immediately, which serves as proof that you paid.

The IRS matches your payment to your tax account using your Social Security number and the tax year and quarter you specify. If you include incorrect information (wrong quarter, wrong year), the payment may be applied to the wrong tax period, and you will need to contact the IRS to correct it. Always double-check the quarter before submitting.

Frequently Asked Questions

What if I miss the quarterly deadline?

You can still send the payment after the deadline. The IRS will apply it to your account, but you may owe a penalty and interest on the late amount. The penalty is calculated from the original due date. Paying late is better than not paying, because it stops interest from accruing further.

Can I pay by mail if I live outside the United States?

Yes, but mailing from outside the U.S. takes much longer and is risky. Use EFTPS or IRS Direct Pay instead—both work for taxpayers with U.S. bank accounts, regardless of where you live. If you do not have a U.S. bank account, a credit or debit card payment through an approved processor is your best option.

Do I need to send Form 1040-ES itself, or just the payment?

You send only the payment voucher (the stub) with your check or money order. Do not send the entire Form 1040-ES. If you are paying electronically, you do not send anything by mail—the payment is submitted online and the IRS records it automatically.

What if I overpay my estimated taxes?

The IRS will hold the overpayment and apply it to your next quarter's payment, or you can request a refund when you file your annual return. You can also direct the overpayment to next year's tax liability. The IRS does not pay interest on overpayments.

How do I know if my payment was received?

If you paid electronically, you have a confirmation number from the payment system. If you mailed a check, keep a copy of the cancelled check or use certified mail with a return receipt. You can also log into your IRS account on IRS.gov to see your payment history and confirm the payment was posted.
