What a 1040-ES Payment Voucher Is and Why You Need It

A 1040-ES voucher is the form you send with your quarterly estimated tax payment to the IRS

The 1040-ES payment voucher is a tear-off slip that comes with Form 1040-ES, the estimated tax form the IRS publishes each year. When you owe federal income tax but do not have an employer withholding it from a paycheck—because you are self-employed, a freelancer, a business owner, or you have investment income—you pay the IRS four times a year instead of once. The voucher is how you tell the IRS which quarter you are paying for, how much you are sending, and who you are.

You do not have to use the voucher if you pay online through the IRS website or through an approved payment processor. But if you mail a check, the voucher goes in the envelope with it. Without it, the IRS has no way to match your payment to your account quickly, and your money may sit unapplied for weeks.

Key Takeaways

The 1040-ES voucher is a one-page form that comes with your estimated tax package and identifies which quarter's payment you are sending.
You only need the voucher if you pay by mail; online payments through IRS Direct Pay or an approved processor do not require it.
The voucher includes your name, address, Social Security number or EIN, the tax year, and the quarter you are paying for.
Mailing your check without the voucher delays the IRS from crediting your account and can create confusion about which quarter you paid.

What information goes on the voucher

The voucher is a small form, usually about 4 by 6 inches, printed at the bottom of each page in the 1040-ES package. You fill in your name, address, Social Security number or employer identification number (EIN), and the tax year. Then you select which quarter you are paying for—Q1 (January through March), Q2 (April through May), Q3 (July through September), or Q4 (October through December)—and write the amount of your payment.

The voucher also has a tear-off section for your records. You keep one copy and mail the other with your check. The IRS uses the information on the voucher to post your payment to the correct quarter and tax year in their system. If you have already filed your tax return for the year, the voucher helps the IRS match the payment to your return as well.

When you actually need to use the voucher

You need the voucher only if you are mailing a check to the IRS. The IRS has a mailing address for each quarter, and the voucher tells them which address to look at and which quarter you are paying. If you pay online through IRS Direct Pay (the IRS's own payment system), you enter the information directly into the website and do not print or mail anything. If you use a third-party payment processor approved by the IRS—such as PayPal, Stripe, or your bank's bill-pay service—those systems also collect the quarter and amount information electronically.

Some people use the voucher as a checklist even when paying online, to make sure they have the right quarter and amount before they submit. But the form itself does not go anywhere.

The four quarterly payment important date

Each quarter has its own due date, and the voucher you use depends on which quarter you are paying for. Q1 is due April 15, Q2 is due June 15, Q3 is due September 15, and Q4 is due January 15 of the following year. If the due date falls on a weekend or federal holiday, the important date moves to the next business day. The IRS publishes the exact dates each year in the 1040-ES instructions.

If you mail your payment, it must be postmarked by the due date. The voucher should be dated the same day you mail it. If you pay online, the payment must be submitted by 11:59 p.m. Eastern time on the due date. The IRS does not accept vouchers for payments made online, so do not try to mail one in addition to an online payment.

How the IRS processes your voucher payment

When your envelope arrives at the IRS service center, a clerk opens it, scans the voucher, and enters the information into the IRS computer system. Your payment is then credited to the quarter and tax year shown on the voucher. This process usually takes two to four weeks, depending on mail volume and the service center's workload. During that time, your payment is in transit and has not yet been posted to your account.

You can track your payment online through the IRS's "Where's My Payment?" tool once it has been posted. The tool shows the date the payment was received and the date it was applied to your account. If you mailed your payment and it has been more than four weeks, you can contact the IRS to ask about the status, though they will ask you to wait at least five weeks before investigating.

What happens if you mail a check without the voucher

If you mail a check without the voucher, the IRS will still receive your money, but it will take longer to post to your account. The IRS will have to match your check to your tax account using only the information on the check itself—your name and the amount. If you have multiple tax accounts (for example, if you are self-employed and also have a business with an EIN), the IRS may post your payment to the wrong account or hold it in suspense while they figure out which account it belongs to.

Without the voucher, you also lose the quarter information. If you are supposed to pay Q2 but the IRS does not know that, they may credit your payment to Q1 or Q4 instead, leaving you short for the quarter you actually owed. This can trigger an underpayment penalty later. For this reason, the IRS strongly recommends using the voucher whenever you mail a check.

Alternatives to mailing vouchers

The IRS offers several ways to pay estimated tax without using a voucher. IRS Direct Pay is free and lets you schedule payments in advance. You enter your payment information on the IRS website, and the money is withdrawn from your bank account on the date you choose. The IRS also accepts payments by debit card or credit card through approved payment processors, though these charge a fee (usually 1 to 2 percent of the payment amount).

Many tax software programs, including TurboTax and H&R Block, have built-in estimated tax payment tools that connect to the IRS system. Your bank's bill-pay service may also offer estimated tax payments. All of these methods eliminate the need for a voucher because the information is transmitted electronically. If you prefer not to mail anything, any of these options will work.

Frequently Asked Questions

Can I use a voucher from last year for this year's payment?

No. The IRS publishes a new 1040-ES package each year with updated vouchers that show the current tax year. If you use an old voucher, the IRS will post your payment to the wrong tax year, and you will have to contact them to correct it. Always use the voucher from the current year's 1040-ES package.

What if I lose the voucher before I mail my check?

You can print a new one from the IRS website or request a replacement from the IRS by phone. You can also write the information on a plain piece of paper: your name, address, Social Security number or EIN, the tax year, the quarter, and the payment amount. The IRS will accept a handwritten note as long as it includes all the required information.

Do I need to mail the voucher if I pay by electronic funds withdrawal?

No. Electronic funds withdrawal (EFW) is a system where the IRS withdraws money directly from your bank account on a date you choose. You set it up through IRS Direct Pay or your tax software, and no voucher is needed. The information is transmitted electronically, so there is nothing to mail.

What address do I mail the voucher to?

The 1040-ES package includes a different mailing address for each quarter. Use the address printed on the voucher for the quarter you are paying. Do not use a general IRS address. The quarterly addresses are designed to route your payment to the correct service center for faster processing.
