How to Pay Estimated Taxes Online (2026)

The fastest way to pay quarterly estimated taxes is IRS Direct Pay — it’s free, needs no account, and confirms in seconds. This guide walks through the actual screens for each payment method so you can send a payment in the next five minutes, and avoid the small mistakes that cause payments to land in the wrong place. (For how much to pay and when, see the quarterly estimated taxes guide.)

Option 1 — IRS Direct Pay (best for most people)

Free, no signup, pulls straight from your bank account. Go to irs.gov/payments/direct-pay and:

Choose “Make a Payment.”
For Reason for Payment, select Estimated Tax.
For Apply Payment To, select 1040-ES.
For Tax Period, select 2026. (This is the step people get wrong — see below.)
Verify your identity using a prior-year return (it asks for filing status, name, and address from a past year).
Enter your bank routing and account numbers and the amount.
Submit and save the confirmation number. You can also have the receipt emailed to you.

That’s it. Direct Pay schedules the debit for the date you choose, up to 365 days out, and you can look up or cancel a scheduled payment with the confirmation number.

Option 2 — EFTPS (best for scheduling the whole year)

The Electronic Federal Tax Payment System (eftps.gov) is free and government-run, but enrollment requires a PIN mailed to you — allow 5–7 business days, so don’t start the week a payment is due. Once enrolled, EFTPS lets you:

Schedule all four quarterly payments at the start of the year.
See a full history of every federal payment in one place.
Manage payments for multiple entities.

It’s the better choice if you want to “set and forget” the full year, or if you run more than one business.

Option 3 — Debit or credit card

The IRS uses third-party processors (linked from irs.gov/payments) that charge a fee — a small flat fee for debit, or roughly 2% for credit. Only worth it if you specifically want the card’s rewards or float; otherwise Direct Pay is free.

Option 4 — Pay by mail with Form 1040-ES

Old-school but allowed. Print the voucher from Form 1040-ES, make a check payable to “United States Treasury,” write your SSN and ”2026 Form 1040-ES” on the memo line, and mail it to the address for your state. The IRS treats the postmark date as the payment date, so mail a few days early.

Don’t make these mistakes

Paying for the wrong year. A payment you make in January 2027 for the Q4 deadline applies to tax year 2026, not 2027. Direct Pay will ask — choose carefully.
Choosing the wrong reason. Estimated payments must be tagged Estimated Tax / 1040-ES, not “Tax Return” or “Balance Due,” or they may post to the wrong account.
Not saving the confirmation. It’s your only proof until the payment shows on your IRS account. Screenshot or save the email.
Forgetting your state. This pays the IRS only. Most income-tax states have their own separate online portal.

When to pay

The 2026 federal deadlines are April 15, June 15, September 15, and January 15, 2027. Pay on or before each date — payments are credited per quarter, so paying late in one quarter can cost you even if you catch up later. (How the penalty and safe harbor work.)

Frequently asked

› What's the easiest way to pay quarterly taxes?

IRS Direct Pay. It's free, requires no enrollment, pulls from your bank account, and gives an instant confirmation number. Choose 'Estimated Tax' and '1040-ES' and select the correct tax year.

› Direct Pay or EFTPS — which should I use?

Direct Pay for one-off quarterly payments with no setup. EFTPS if you want to schedule all four payments at once or track a full payment history — but enrollment needs a PIN mailed to you, so set it up well ahead of a deadline.

› Is there a fee to pay estimated taxes online?

No fee with Direct Pay or EFTPS (both pull from a bank account). Debit and credit card payments go through third-party processors that charge a fee — a small flat amount for debit, around 2% for credit.

› How do I know my payment went through?

Save the confirmation number Direct Pay or EFTPS gives you, and optionally the emailed receipt. The payment will also appear in your IRS online account, usually within a few days.
