Send estimated tax payments to the IRS, not your state or local tax office

Estimated federal tax payments go to the Internal Revenue Service through one of two channels: the Electronic Federal Tax Payment System (EFTPS) or the IRS Direct Pay system. Both are free. You do not mail a check to an IRS office or send payment to your state tax authority — the IRS handles federal estimated taxes separately from state and local taxes, and routing your payment to the wrong place delays processing and can trigger penalties.

The method you choose depends on how you prefer to move money and whether you want automatic scheduling. EFTPS requires enrollment but lets you schedule payments weeks in advance. IRS Direct Pay is faster to set up but requires you to initiate each payment individually. Both deduct from your bank account directly; neither accepts credit cards.

Key Takeaways

  • The IRS receives federal estimated tax payments through EFTPS or IRS Direct Pay, both free and both drawing from your bank account.
  • EFTPS requires advance enrollment but lets you schedule payments automatically on future due dates.
  • IRS Direct Pay has no enrollment step and works when ready, but you must initiate each payment yourself.
  • Mailing a check is an option only if you cannot use electronic payment, and it takes longer to post to your account.
  • State and local estimated tax payments go to your state tax authority, not the IRS, and use separate systems.

Electronic Federal Tax Payment System (EFTPS)

EFTPS is the IRS's official payment platform for estimated taxes, payroll taxes, and other federal obligations. You enroll once with your Social Security Number or Employer Identification Number, a bank account, and a routing number. Enrollment takes about 10 minutes online at eftps.gov, though the IRS mails a PIN to your address within two weeks — you need this PIN to log in for the first time.

Once enrolled, you can schedule payments up to 120 days in advance. This matters if you know your estimated tax liability for the quarter and want to set it and forget it. You choose the payment date, the amount, and the tax period it covers (Q1, Q2, Q3, or Q4). The payment posts to the IRS within one business day if you schedule it before 10:59 p.m. Eastern Time; after that cutoff, it posts the next business day.

EFTPS also lets you make same-day payments if you have not enrolled yet — you can pay as a guest without creating an account, though you will need to re-enter your information each time. Guest payments are useful if you only pay once or twice a year and do not want to manage an account.

IRS Direct Pay

IRS Direct Pay is faster to start but requires more active management. You go to irs.gov/payments, enter your Social Security Number or EIN, your filing status, and your bank account details, and make a payment when ready. There is no enrollment, no PIN, no waiting period. The payment posts within one business day using the same timing as EFTPS: before 10:59 p.m. Eastern Time posts same day, after that posts the next business day.

The trade-off is that you must initiate each payment separately. If you have four quarterly payments, you log in four times and enter your information four times. Direct Pay does not let you schedule payments in advance or set up recurring payments. It is best for people who pay infrequently or prefer to pay only when they have cash on hand.

Direct Pay also provides a confirmation number when ready after you submit payment, which you can use to track the transaction. EFTPS provides a confirmation number as well, but it appears in your account after the payment posts.

Mailing a check (if you cannot pay electronically)

The IRS accepts mailed checks, but processing takes longer and the timing is harder to control. You write a check payable to "United States Treasury," write your Social Security Number or EIN on the check, and include Form 1040-ES (for individuals) or the appropriate form for your entity type. The address depends on where you live; the IRS publishes a state-by-state list on irs.gov.

A mailed payment is considered received on the date the IRS receives it, not the date you mail it. Mail typically takes 5 to 10 business days, and the IRS processes it after receipt. If your payment arrives after the due date, you may owe penalties and interest even if you mailed it on time. For this reason, the IRS recommends mailing at least one week before the due date.

Mailing is also the slowest way to confirm your payment posted. You will not see it in your IRS account for several weeks. If you need proof of payment quickly — for a loan process or to show a lender you paid on time — electronic payment gives you confirmation the same day.

Payment due dates and how to know which quarter you owe

Estimated tax payments are due on the 15th of April, June, September, and January. If the 15th falls on a weekend or federal holiday, the due date moves to the next business day. These dates correspond to Q1 (January–March), Q2 (April–June), Q3 (July–September), and Q4 (October–December).

When you submit a payment through EFTPS or Direct Pay, you specify which quarter the payment covers. The IRS uses this information to explore the payment to the correct tax period. If you mail a check, write the quarter on the check itself so the IRS knows which period to assign it to. Assigning a payment to the wrong quarter can delay crediting and trigger unnecessary penalties.

You can make estimated tax payments even if you have not filed a tax return yet, as long as you have a Social Security Number or EIN. The IRS will match the payment to your return when you file.

Tracking your payment and confirming it posted

Both EFTPS and Direct Pay give you a confirmation number when ready after you submit payment. Write this number down or save the confirmation email. The confirmation number lets you track the payment through the IRS system and proves you paid on time if there is ever a dispute.

You can also check your payment history in your IRS account at irs.gov/account. Log in with your Social Security Number or EIN and view all payments made in the past three years, including the date posted and the amount. Payments typically appear in your account within one to three business days of posting.

If a payment does not appear after five business days, contact the IRS at 800-829-1040 (individuals) or 800-829-4933 (businesses) with your confirmation number. Do not assume the payment was lost; the IRS processes millions of payments and delays of a few days are normal.

State and local estimated tax payments are separate

If you owe state or local estimated taxes, those payments go to your state tax authority, not the IRS. Each state has its own payment system and due dates. Some states align with federal quarters (April 15, June 15, September 15, January 15), but others use different schedules. A few states do not require estimated tax payments at all.

Check your state tax authority's website for payment instructions. Most states offer electronic payment through their own portal, similar to EFTPS or Direct Pay. Some allow mailed checks. The state will tell you where to send payment and what information to include.

Frequently Asked Questions

What happens if I send my estimated tax payment to the wrong address?

If you mail a check to an incorrect IRS address, it may be returned to you or forwarded to the correct processing center, which delays posting. Electronic payments through EFTPS or Direct Pay go to the correct IRS system automatically, so this is not a risk. If you mailed a check and are unsure whether it arrived, contact the IRS with your confirmation details or check your IRS account after 10 business days.

Can I pay my federal estimated taxes by credit card?

No. The IRS does not accept credit cards for estimated tax payments through EFTPS or Direct Pay. Both systems deduct from your bank account only. If you want to use a credit card, third-party payment processors accept credit cards but charge a fee (typically 1.87% to 2.35% of the payment amount), which you must pay separately.

Do I need to enroll in EFTPS before my first payment is due?

No. You can make a guest payment through EFTPS without enrolling, or use Direct Pay, which requires no enrollment at all. However, if you plan to make multiple payments, enrolling in EFTPS lets you schedule payments in advance and saves time on repeat visits.

What if I overpay my estimated taxes?

The IRS credits the overpayment to your next estimated tax payment or applies it to your annual tax return when you file. You can also request a refund, though the IRS typically prefers to credit the amount forward. Specify your preference when you file your return.

How do I know if my payment posted on time?

Check your IRS account at irs.gov/account within three business days of payment. Your payment history shows the date it posted. If the posted date is on or before the due date, you paid on time. Keep your confirmation number from EFTPS or Direct Pay as proof in case you need it later.
