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

The IRS has different mailing addresses depending on whether you are paying by check, money order, or electronic transfer. You will also use different addresses based on which state you live in. The simplest route is to pay electronically through the IRS website or a payment processor — this eliminates the need to find an address and reduces the chance of your payment getting lost in the mail.

If you must mail a check or money order, the address you use depends on your state. The IRS publishes a list of state-specific addresses on its website, and you should verify the current address before mailing because these occasionally change. Never send a payment to a local IRS office or tax professional — the IRS only accepts mailed 1040-ES payments at specific processing centers.

Key Takeaways

  • Electronic payment through IRS Direct Pay, the Electronic Federal Tax Payment System (EFTPS), or an approved payment processor is the fastest and most reliable method.
  • If you mail a check or money order, you must use the state-specific address listed on the IRS website, not your local tax office.
  • Your payment must include your name, address, Social Security number, tax year, and the amount on the check or money order itself.
  • Mailed payments typically take two to three weeks to process, so send them early enough that they arrive before the due date.
  • The IRS accepts 1040-ES payments on a quarterly schedule: April 15, June 15, September 15, and January 15 of the following year.

Paying electronically through the IRS website

The IRS offers free electronic payment through IRS Direct Pay, which is the fastest option if you have a bank account. You log in at irs.gov, enter your payment amount and due date, and authorize a debit from your checking or savings account. The payment posts within one business day, and you receive a confirmation number when ready. This method works from any computer or mobile device and requires no special software.

Direct Pay is free and does not require you to set up an account in advance — you can make a payment the same day you decide to pay. The IRS processes the payment on the date you specify, so you can schedule it to arrive on or before the due date without guessing how long the mail will take.

Using EFTPS for recurring quarterly payments

The Electronic Federal Tax Payment System (EFTPS) is designed for people who make regular estimated tax payments. You enroll once, and then you can schedule payments online or by phone without re-entering your bank details each time. EFTPS is also free and takes one business day to process.

EFTPS requires you to enroll at least one business day before your first payment, so it is not useful if you need to pay today. However, if you know you will be making quarterly payments for the next year or longer, the enrollment takes about 10 minutes and saves time on future payments. The IRS mails you an enrollment confirmation with a PIN, which you use to log in.

Paying through a third-party payment processor

The IRS approves certain payment processors to accept 1040-ES payments on its behalf. These companies charge a fee — typically between $2 and $4 per transaction — but some people use them because they offer additional features like scheduling multiple payments at once or integrating with accounting software.

You can find the current list of approved processors on the IRS website under "Payment Processors." Each processor has its own website and enrollment process. If you use a processor, verify that it is on the IRS list before entering your bank details, because scammers sometimes create fake payment sites that look like official IRS processors.

Mailing a check or money order by state

If you cannot pay electronically, you can mail a check or money order. The address depends on your state of residence. The IRS publishes the complete list of mailing addresses on its website under "Where to File" — search for your state name and "1040-ES." Do not use an address you find anywhere else, because outdated addresses circulate online and payments sent to the wrong location may be delayed or lost.

Write your Social Security number, the tax year (for example, "2024"), and "1040-ES" on the check or money order itself. Include a cover letter with your name, address, and phone number. Mail the payment at least two weeks before the due date to account for postal delays. The IRS does not send a receipt for mailed payments, so keep a copy of your check or the money order receipt as proof of payment.

What information to include with your payment

Whether you pay electronically or by mail, the IRS needs to match your payment to your tax account. For electronic payments, the system captures your information automatically when you log in. For mailed payments, you must write the following on the check or money order: your full name, your Social Security number, the tax year, and "1040-ES."

If you are paying as a business owner or self-employed person, use your Social Security number, not an EIN, unless you file as a corporation. If you are married and filing jointly, use the Social Security number of the first spouse listed on your tax return. Payments without this information may be applied to the wrong account or held while the IRS tries to match them.

Timing and quarterly due dates

The 1040-ES has four due dates per year. The first quarter payment is due April 15, the second is due June 15, the third is due September 15, and the fourth is due January 15 of the following year. If a due date falls on a weekend or federal holiday, the important date moves to the next business day.

If you pay electronically, you can schedule the payment to post on the due date itself — you do not need to send it early. If you mail a check, the IRS considers the payment on time if it is postmarked by the due date, even if it arrives later. However, most people mail payments at least one week early to be safe. If you miss a due date, you may owe a penalty and interest, so contact the IRS if you cannot pay on time.

Frequently Asked Questions

Can I pay my 1040-ES payment at a bank or post office?

No. Banks and post offices do not accept 1040-ES payments directly. You must pay through the IRS website, an approved payment processor, or by mailing a check to the IRS address for your state. Some tax software programs also allow you to pay through their platforms, which then routes your payment to the IRS.

What happens if I mail my payment to the wrong address?

The payment may be delayed or returned to you. If you realize you sent it to the wrong address, contact the IRS when ready at 1-800-829-1040 to report it. The IRS can sometimes intercept mailed payments and reroute them, but this is not may provide. Always verify the correct address on the IRS website before mailing.

Do I need to include a 1040-ES form with my payment?

No. You do not mail the form itself. The form is a worksheet you use to calculate how much to pay. When you pay electronically or by mail, you only send the payment amount — the IRS tracks which quarter it is for based on the due date you specify or the postmark date on your envelope.

Can I pay multiple quarters at once?

Yes. You can pay all four quarters in a single transaction if you want to, though most people pay quarterly as the due dates arrive. If you pay early, specify which quarter each payment is for so the IRS applies it correctly. Electronic payment systems usually ask you to select the quarter when you set up the payment.

Is there a penalty if I pay late?

Yes. If you miss a due date, the IRS charges a penalty and interest on the unpaid amount. The penalty is usually 0.5% per month of the unpaid tax. If you cannot pay by the due date, paying as soon as possible afterward reduces the total penalty. Contact the IRS if you need to discuss a payment plan.
