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 pay by check, money order, or electronic transfer. If you are paying by mail, the address you use depends on which state you live in. The IRS publishes a full list of state-specific addresses on Form 1040-ES itself, in the instructions section labeled "Where to File." If you pay electronically through the IRS Direct Pay system or through a tax professional's software, you do not mail anything — the payment goes directly to the IRS.

The fastest and most reliable method is electronic payment. You can pay through IRS Direct Pay (a free service at irs.gov), through the Electronic Federal Tax Payment System (EFTPS), or through tax software that handles payments. Electronic payments clear within one business day and create an automatic receipt with a confirmation number. If you must mail a check or money order, allow at least two weeks for the IRS to receive and process it, and include your Social Security number and tax year on the payment itself.

Key Takeaways

  • Electronic payment through IRS Direct Pay or EFTPS is faster and safer than mailing a check, and both services are free.
  • If you mail a check or money order, use the state-specific address listed in the Form 1040-ES instructions, not a general IRS address.
  • Write your Social Security number and the tax year on any mailed payment so the IRS can match it to your account.
  • Electronic payments post within one business day and give you an immediate confirmation number; mailed payments take two to three weeks to process.
  • The IRS will not accept 1040-ES payments at local tax offices or through third-party payment processors unless you use an authorized service like EFTPS.

Electronic payment through IRS Direct Pay

IRS Direct Pay is a free service that lets you pay directly from your bank account without giving your banking information to a third party. You go to irs.gov/payments, select "Pay Now," and choose Direct Pay. You will need your Social Security number, date of birth, street address, and your bank account and routing numbers. The system confirms the payment immediately and gives you a confirmation number.

You can schedule a payment up to 120 days in advance, which is useful if you want to set up all four quarterly payments at once. The payment posts to your IRS account within one business day. If you need to change or cancel a payment, you can do so up to one business day before the scheduled payment date through the same system.

EFTPS (Electronic Federal Tax Payment System)

EFTPS is the IRS's official electronic payment system, and it works similarly to Direct Pay but requires you to enroll first. You set up an account at eftps.gov, provide your banking information, and then make payments whenever you need to. EFTPS also lets you schedule payments in advance and works for all types of federal tax payments, not just estimated taxes.

Enrollment takes one to two business days. Once you are enrolled, you can make payments immediately. Like Direct Pay, EFTPS is free and posts within one business day. Some people prefer EFTPS because it creates a record of all your federal tax payments in one place, which can be useful if you pay multiple types of taxes (income, self-employment, payroll).

Mailing a check or money order by state

If you must mail your payment, the address depends on your state. The Form 1040-ES instructions include a table with mailing addresses for each state. For example, if you live in California, you mail to a different address than if you live in New York. Do not use a general IRS address or your local tax office address — use only the address listed for your state in the Form 1040-ES instructions.

Write your Social Security number, the tax year, and "1040-ES" on the front of your check or money order. Include a copy of the payment voucher from Form 1040-ES (the tear-off section at the bottom of the form). Mail your payment at least two weeks before the due date to account for postal delays. The IRS processes mailed payments in the order they are received, so late mail can result in a late payment penalty even if you mailed it on time.

Payment due dates for quarterly estimated taxes

Estimated tax payments are due four times per year. The due dates are April 15, June 15, September 15, and January 15 of the following year. If a due date falls on a weekend or federal holiday, the deadline moves to the next business day. For electronic payments, the deadline is 11:59 p.m. Eastern Time on the due date. For mailed payments, the postmark date must be on or before the due date.

If you miss a due date, the IRS will charge a penalty and interest on the unpaid amount. The penalty is typically 0.5% of the unpaid tax per month, though it varies. You can still make a late payment, but you will owe the penalty and interest in addition to the tax itself. If you expect to miss a deadline, paying as soon as possible after the due date limits how much interest accrues.

What to do if you cannot pay by the due date

If you cannot pay the full amount by the due date, pay whatever you can by the deadline. The penalty and interest apply only to the unpaid portion, not to the amount you paid on time. You can also set up a payment plan with the IRS if you owe a large amount. Short-term payment plans (120 days or less) are free; long-term plans charge a setup fee.

Contact the IRS at 1-800-829-1040 to discuss a payment plan, or set one up online through the IRS website. If you are having financial hardship, you may be able to request a temporary delay in payment, though this is rare and requires documentation of the hardship.

Confirming your payment was received

If you pay electronically, you receive a confirmation number immediately. Write this number down and keep it with your tax records. You can check the status of your payment on the IRS website by logging into your account or calling 1-800-829-1040.

If you mail a check or money order, do not expect a receipt in the mail. The IRS will post the payment to your account once it is processed, which takes two to three weeks. You can check the status of your payment online through the IRS website or by calling the IRS. If your payment does not appear in your account after three weeks, contact the IRS to confirm it was received.

Frequently Asked Questions

Can I pay my 1040-ES through a credit card or PayPal?

The IRS does not accept credit cards or PayPal directly. You can pay through third-party payment processors approved by the IRS, but they charge a fee (usually 1.87% to 2.35% of the payment). IRS Direct Pay and EFTPS are free, so those are the best options if you have a bank account.

What happens if I overpay my estimated taxes?

If you pay more than you owe, the IRS will either refund the overpayment or apply it to your next year's taxes. You can choose which option you prefer when you file your annual return. There is no penalty for overpaying.

Do I need to include a voucher when I mail my payment?

Yes. The Form 1040-ES includes a tear-off payment voucher at the bottom. Include this voucher with your check or money order so the IRS can match the payment to your account. If you do not include the voucher, the payment may be delayed or misapplied.

Can I pay all four quarterly payments at once?

Yes. You can pay all four quarters at once through IRS Direct Pay or EFTPS, or you can schedule them in advance so they post on each due date. If you mail checks, you can send all four at once, but the IRS will process them as separate payments on the dates they are received.

What if I move during the tax year?

If you move, use your new address on any future payments. If you have already made payments to an old address, contact the IRS to update your address so the payments are correctly applied to your account. Electronic payment avoids this problem because there is no address involved.
