How to Pay Estimated Taxes Online

1. Open Direct Pay on IRS.gov and choose to make a payment. No account or login is needed.
2. Choose estimated tax as the reason, apply it to Form 1040-ES, and pick the tax year: 2026 for any payment covering 2026 income, including the one due January 15, 2027.
3. Verify your identity with details from a prior-year return. You cannot use the year you are paying for, and Direct Pay will not work if you have never filed.
4. Enter your bank routing and account numbers and a payment date. You can schedule up to 365 days ahead.
5. Save the confirmation number or have it emailed. Direct Pay cannot look it up later, and you need it to change or cancel the payment.

Limits worth knowing:

• Up to five payments in 24 hours, each under $9,999,999.99.
• You can change or cancel until two business days before the payment date.
• Payments submitted after 8 p.m. Eastern generally post as the next business day. On a due date, pay earlier in the day.

EFTPS is the Treasury's free payment system. It needs enrollment and a PIN that arrives by mail, typically in five to seven business days. In return, you can schedule every installment for the year in one sitting, up to 365 days ahead, and see a full payment history.

The timing rule is stricter than Direct Pay: a payment is on time only if it is scheduled by 8 p.m. Eastern at least one calendar day before the due date. For January 15, 2027, schedule by 8 p.m. Eastern on Thursday, January 14. If you have not enrolled yet, enroll in the first days of January or use Direct Pay instead.

Your IRS Online Account lets you make a payment from a bank account and, more usefully, see the payments the IRS has actually received and the tax year each was applied to. It requires a one-time identity verification, which is the slow part.

Even if you pay through Direct Pay or EFTPS, log in before you file. A 2026 payment that posted to 2027 shows up there months before it shows up as a notice.

IRS-approved processors take debit cards, credit cards and digital wallets for estimated tax. Fees as of October 2026: $2.10 or $2.15 flat for debit, 1.75% or 1.85% for credit with a $2.50 minimum. None of the fee goes to the IRS, and frequency limits apply to card payments in each period.

Two other routes exist for edge cases. Retail cash payments work through approved partners but need to be set up in advance. A same-day wire through your bank suits a very large payment on a due date, but banks charge for it and you must complete the IRS same-day taxpayer worksheet.

Checks still work as of October 2026, although the IRS is encouraging everyone toward electronic payment under Executive Order 14247 and has already ended most paper refund checks. If you mail:

• Make the check payable to U.S. Treasury.
• Write your SSN (the first SSN on a joint return), the tax year, and "2026 Form 1040-ES" on the memo line.
• Include the matching voucher from Form 1040-ES and mail to the address for your state in the Form 1040-ES instructions.
• Use certified mail if the payment is large. A timely postmark generally counts as timely payment, and the receipt is your proof.

How you pay is the easy part. How much is the part that triggers penalties. Most high earners pay one quarter of the prior-year safe harbor each installment, which the estimated tax payments guide walks through, and check themselves with the estimated tax penalty calculator.
