Where to pay estimated taxes online

The IRS accepts estimated tax payments through IRS Direct Pay, which is free and takes about 10 minutes. You go to irs.gov/payments, enter your tax ID and payment amount, and choose your bank account or debit card as the funding source. The IRS confirms your payment immediately and gives you a confirmation number.

If you prefer not to link a bank account, you can use a credit or debit card through approved payment processors — currently Authorize.Net, Paymetrics, and WorldPay. These processors charge a convenience fee (usually 1.87% to 2.49% of the payment) that you pay on top of your tax amount. The fee is not deductible.

Some states also accept online estimated tax payments through their own tax department websites. If you owe both federal and state estimated taxes, you will need to make two separate payments — one to the IRS and one to your state. Check your state's tax website for the payment portal and any fees they charge.

Key Takeaways

  • IRS Direct Pay is free and works with your bank account or debit card, and you get a confirmation number immediately.
  • Credit card payments through third-party processors charge a fee of roughly 2% on top of your payment amount.
  • You need your Social Security Number or Employer Identification Number, the payment amount, and the tax period the payment covers.
  • The IRS processes most online payments within one business day, and you can track your payment status using your confirmation number.
  • State estimated tax payments are separate from federal payments and must be made through your state's tax department website.

What information you need before you start

Have your Social Security Number (if you are self-employed or a sole proprietor) or Employer Identification Number (if you operate as an S-corp, C-corp, partnership, or LLC) ready. The IRS will ask for this to match your payment to your account.

You also need to know which tax period the payment covers. Estimated taxes are due in four installments tied to calendar quarters: January 1 through March 31 (due April 15), April 1 through May 31 (due June 15), June 1 through August 31 (due September 15), and October 1 through December 31 (due January 15 of the following year). When you make the payment, you tell the IRS which quarter it is for.

Finally, know the exact amount you want to pay. This is the number you calculated on your Form 1040-ES or the amount your accountant told you to send. The IRS does not calculate this for you — you enter it yourself.

Step-by-step process for IRS Direct Pay

Go to irs.gov/payments and select "IRS Direct Pay" from the payment options. You will land on a page that says "Pay Your Federal Taxes Online" with a blue button to begin.

Click the button and you will be asked to enter your tax ID (SSN or EIN). The system will ask whether you are paying as an individual, business, or on behalf of someone else. Choose the option that matches your situation. If you have never used Direct Pay before, you will create a login or use an existing IRS online account.

Enter the payment amount and select the tax period (quarter) it covers. The system will show you a summary. Review it carefully — once you confirm, the payment is submitted. Then choose your funding source: bank account (via ACH transfer) or debit card. If you use a bank account, provide your routing number and account number. If you use a debit card, enter the card details.

The IRS will ask you to confirm the payment one more time. After you do, the system generates a confirmation number. Write this down or take a screenshot — you will need it if you ever need to check the status of the payment or dispute it later.

How long the payment takes to reach the IRS

IRS Direct Pay payments are usually posted to your account within one business day. If you pay on a Friday, expect it to show up by Monday. If you pay on a weekend or holiday, it will post on the next business day.

Credit card payments through third-party processors also typically post within one business day, though the processor's website will tell you the exact timeline when you submit the payment.

The IRS considers a payment made on the date you submit it online, not the date it actually clears your bank account. This matters for the estimated tax deadline — if the deadline is April 15 and you submit the payment on April 15, you are on time even if your bank does not deduct the money until April 17.

Tracking your payment after you submit it

Use your confirmation number to check the status of your payment. Go back to irs.gov/payments and select "Check Payment Status." Enter your confirmation number and tax ID, and the system will tell you whether the payment has been received and posted.

If you used IRS Direct Pay, you can also log into your IRS online account (through irs.gov) and view your payment history there. The account shows all payments you have made in the current and prior years, along with the dates they posted.

Do not assume a payment is lost if it does not show up immediately. Most payments take one business day. If more than two business days have passed and the payment still does not appear, contact the IRS at 800-829-1040 with your confirmation number ready.

What to do if you make a mistake or need to change your payment

If you submitted the wrong amount or the wrong tax period, you cannot cancel an online payment once it has been submitted. However, you can make an additional payment to correct it. If you overpaid, the IRS will credit the excess toward your next estimated payment or your annual tax return, depending on what you request.

If you underpaid, simply make another payment for the difference. There is no penalty for splitting a single quarter's payment into two submissions — the IRS only cares that the total amount is paid by the deadline.

If you realize the mistake before the payment posts (usually within a few hours), contact the IRS immediately at 800-829-1040 with your confirmation number. They may be able to stop the payment, though this is not may provide.

State estimated tax payments online

Most states that impose income tax allow you to pay estimated taxes online through their tax department website. Search "[your state] estimated tax payment online" to find the portal. Some states use the same payment system for all tax types (income, sales, payroll); others have a separate estimated tax section.

State payment deadlines usually match the federal deadlines (April 15, June 15, September 15, January 15), but a few states use different dates. Check your state's website to confirm. Some states charge a fee for online payments; others do not.

A few states do not accept online estimated payments and require you to mail a check or use an automated phone system. If your state does not have an online portal, call the state tax department to ask about alternatives.

Frequently Asked Questions

Can I pay estimated taxes with a credit card without a fee?

No. Credit card payments through the IRS always go through a third-party processor that charges a convenience fee. IRS Direct Pay is free, but it only accepts bank accounts and debit cards. If you want to avoid a fee, use your bank account or debit card through Direct Pay instead.

What if I miss the estimated tax deadline?

You can still make the payment after the deadline. The IRS will charge you a penalty and interest on the late amount, calculated from the original due date. The sooner you pay, the less interest accrues. Pay online using the same method you would use for an on-time payment.

Do I need to mail a voucher with my online payment?

No. Online payments do not require a voucher. The IRS links your payment to your account automatically using your tax ID. Keep your confirmation number for your records, but do not mail anything to the IRS.

Can I set up automatic estimated tax payments?

IRS Direct Pay does not offer automatic recurring payments. You must submit each quarterly payment manually. Some third-party tax software (like TurboTax or TaxAct) offers a reminder service that alerts you before each deadline, but you still make the payment yourself.

What if I overpay my estimated taxes?

The IRS will hold the overpayment and credit it toward your next estimated payment or your annual tax return. When you file your return, you can choose to receive a refund of any remaining overpayment or have it applied to next year's taxes.
