The three ways to send estimated tax payments

You can pay estimated taxes to the IRS through IRS Direct Pay, Electronic Federal Tax Payment System (EFTPS), or by mailing a check. Direct Pay is the fastest and requires no setup—you go to IRS.gov, enter your information, and schedule a payment for any date up to the due date. EFTPS takes a few days to set up but lets you schedule multiple payments at once and works for both individual and business taxes. A mailed check takes the longest and requires you to include Form 1040-ES (for individuals) or the correct voucher for your business type.

Each method posts to your account at different speeds. Direct Pay and EFTPS both show as received within one business day if you pay before the cutoff time (usually around 8 p.m. Eastern). A mailed check can take two to three weeks to clear, depending on where the IRS processes it. If you are close to a due date, use Direct Pay or EFTPS to avoid late penalties.

The IRS charges no fee for any of these methods. Third-party payment processors that advertise on search results may charge a convenience fee—these are optional and not required by the IRS.

Key Takeaways

  • IRS Direct Pay is the fastest method and requires no advance setup; you can schedule a payment for any date up to the due date on the same day you decide to pay.
  • EFTPS requires a one-time setup that takes a few days, but then lets you schedule multiple quarterly payments in advance and works for self-employed and business taxes.
  • Mailed checks must include the correct form or voucher and take two to three weeks to post, so use this method only if you cannot pay electronically.
  • The IRS due dates for estimated taxes are April 15, June 15, September 15, and January 15 of the following year; payments are due by 11:59 p.m. Eastern on those dates.
  • If you miss a due date, pay as soon as you can—the IRS charges a failure-to-pay penalty that accrues daily, but it stops once you submit the payment.

Setting up IRS Direct Pay

Go to IRS.gov and search for "IRS Direct Pay" or navigate to the payments section. You will need your Social Security number or Employer Identification Number (EIN), your date of birth, and your bank account number and routing number. The IRS will verify your identity by asking questions based on your tax history—this takes a few minutes and happens in real time.

Once verified, you enter the payment amount, select the tax year and quarter the payment covers, and choose the date you want the money to leave your bank account. Direct Pay accepts payments up to the due date at 11:59 p.m. Eastern. You will receive a confirmation number immediately; save this for your records. The payment posts to your IRS account within one business day.

Direct Pay works for individual estimated taxes (Form 1040-ES), corporate taxes, partnership taxes, and S-corporation taxes. If you are self-employed and paying both income tax and self-employment tax, Direct Pay handles both in a single transaction.

Setting up EFTPS for recurring payments

EFTPS is the IRS's official electronic payment system and is the best choice if you pay estimated taxes every quarter and want to schedule them all at once. Go to EFTPS.gov and create an account using your SSN or EIN, bank account number, and routing number. The IRS mails you an enrollment confirmation letter within five to seven business days; you cannot make payments until you receive and activate this letter.

Once activated, you log in and schedule payments for any date up to the due date. You can enter all four quarterly payments for the year in one session. EFTPS deducts the money from your bank account on the date you specify and posts it to your IRS account within one business day. If you need to change a scheduled payment, you can do so up to two business days before the payment date.

EFTPS also lets you set up a payment plan if you cannot pay the full amount by the due date. You can request an installment agreement directly through EFTPS, though the IRS will charge a setup fee and monthly interest on the unpaid balance.

Mailing a check or money order

If you cannot pay electronically, you can mail a check or money order. For individual estimated taxes, include Form 1040-ES with your payment. Write your SSN, the tax year, and the quarter on the check itself (for example, "2024 Q2 Estimated Tax"). Mail it to the IRS address listed in the Form 1040-ES instructions—this varies by state.

For business estimated taxes, use the voucher that came with your tax forms or download it from IRS.gov. Self-employed filers use Form 1040-ES; C-corporations use Form 1120-W; S-corporations and partnerships use Form 1065-ES. Write the same information on the check and mail it to the correct address for your state.

The IRS receives mail at regional processing centers, and it can take two to three weeks for your payment to post to your account. To be safe, mail your check at least one week before the due date. If the due date falls on a weekend or holiday, the IRS extends the deadline to the next business day, but do not rely on this—mail early.

What happens if you miss a due date

If you miss a quarterly due date, the IRS charges an underpayment penalty on the amount you should have paid. This penalty accrues daily from the due date until you pay. The rate changes each quarter and is based on the federal short-term interest rate plus 3 percent. For 2024, the rate is around 8 percent annually, but this varies.

Pay the missed amount as soon as you can using Direct Pay or EFTPS. The penalty stops accruing once the payment posts to your account. You do not need to contact the IRS or file a special form—the penalty is calculated automatically when you file your annual tax return. If you underpaid significantly, the IRS may also charge a failure-to-pay penalty on top of the underpayment penalty, but both are reduced if you pay before filing your return.

If you expect to owe a large amount at tax time and cannot pay all four quarters, pay what you can each quarter. The penalty is calculated on the shortfall for each quarter, so paying something is better than paying nothing.

Tracking your payment status

After you make a payment through Direct Pay or EFTPS, you receive a confirmation number. Save this number. You can check the status of your payment on IRS.gov using the "Where's My Payment?" tool or by logging into your IRS account at IRS.gov/account.

Payments made through Direct Pay or EFTPS post within one business day. Mailed checks take longer—check your account after two to three weeks. If your payment does not appear after that time, contact the IRS at 1-800-829-1040 and have your confirmation number or check number ready.

Your IRS account also shows your payment history, your current balance, and any penalties or interest owed. This is the official record the IRS uses, so if there is a discrepancy between what you paid and what the IRS shows, your account is the source of truth.

Frequently Asked Questions

Can I pay estimated taxes late without a penalty?

No. The IRS charges an underpayment penalty starting on the due date, even if you pay one day late. The only exception is if the due date falls on a weekend or federal holiday—the deadline moves to the next business day. Pay by 11:59 p.m. Eastern on the due date to avoid penalties.

What if I overpay my estimated taxes?

If you pay more than you owe for the year, the IRS credits the overpayment to your next tax bill or refunds it to you when you file your return. You can also request a refund immediately by contacting the IRS, though most people wait and apply the credit to the next year's taxes.

Do I have to make four payments, or can I pay all at once?

You can pay all at once if you want, but the IRS expects four equal payments on the quarterly due dates. If you pay everything in one lump sum early in the year, you may still owe an underpayment penalty for the quarters you did not pay on time. Spread payments across the four quarters to avoid penalties.

What if my income changes during the year?

You can adjust your estimated tax payments if your income changes. Recalculate what you expect to owe for the full year and adjust the remaining quarterly payments. You do not need to file a form—just change the amount on your next Direct Pay or EFTPS payment. If you overpay early quarters, the IRS will credit the overpayment to later quarters or refund it at tax time.

Can I use a credit card or debit card to pay estimated taxes?

The IRS does not accept credit or debit cards directly. Third-party payment processors on IRS.gov accept cards but charge a convenience fee (usually 1.87 to 2.35 percent of the payment). Direct Pay and EFTPS are free and use bank accounts only. If you must use a card, factor the fee into your payment amount.
