The main federal tax deadline is April 15, but it shifts to the next business day if April 15 falls on a weekend or federal holiday

The standard deadline for federal income tax returns and payments is April 15. However, if April 15 lands on a Saturday, Sunday, or federal holiday (like Juneteenth on June 19), the IRS moves the deadline to the next business day. In 2024, April 15 was a Monday, so the deadline was April 15. In 2025, April 15 is a Sunday, which means the deadline moves to Monday, April 16. Check the IRS website each year to confirm the exact date, because it changes.

If you file an extension using Form 4868, you get until October 15 to file your return, but this does not extend the payment deadline. Any tax you owe is still due on the original April deadline. Paying late triggers penalties and interest, even if you filed an extension. The penalty for paying late is typically 0.5% of the unpaid tax per month, plus interest that compounds daily.

Estimated tax payments follow a different schedule. If you are self-employed or have income not subject to withholding, you make four quarterly payments throughout the year: April 15, June 17, September 16, and January 15 of the following year. These dates also shift if they fall on weekends or holidays.

Key Takeaways

  • The main tax deadline is April 15, but it moves to the next business day if April 15 is a weekend or federal holiday.
  • Filing an extension moves your return deadline to October 15 but does not extend the payment deadline—tax owed is still due April 15.
  • Paying after the deadline triggers a 0.5% monthly penalty plus daily interest on the unpaid amount.
  • Quarterly estimated tax payments are due April 15, June 17, September 16, and January 15, with dates shifting for weekends and holidays.
  • The IRS accepts payments by check, electronic transfer, credit card, and direct debit, each with different processing times.

How the IRS processes different payment methods

Check payments sent by mail should arrive at the IRS address listed on the Form 1040 instructions at least seven business days before the deadline. The IRS processes checks slowly, and a check that arrives on time but clears after the deadline still counts as late. Mail your check early enough that it arrives with time to spare.

Electronic Federal Tax Payment System (EFTPS) is the IRS's free payment platform. You enroll once, then schedule payments online or by phone. EFTPS allows you to schedule a payment up to 120 days in advance. If you schedule a payment for April 15, it must be submitted by April 14 at 11:59 p.m. Eastern time to process on time. EFTPS is the safest method because the IRS confirms your payment immediately.

Credit card and debit card payments go through third-party processors approved by the IRS: Worldpay, PayPal, Stripe, and Square. You pay a convenience fee (usually 1.87% to 2.35% of the payment) on top of your tax bill. The payment posts immediately to your account, but the IRS may not receive it for one to two business days. Schedule card payments at least two business days before the deadline to be safe.

Direct debit from your bank account through IRS Direct Pay is free and the fastest method. You enter your routing and account number, and the IRS pulls the payment on the date you specify. If you schedule a payment for April 15, it must be submitted by April 14 at 11:59 p.m. Eastern time. The money leaves your account on the date you choose, so verify you have funds available.

What happens if you miss the deadline

The IRS charges a failure-to-pay penalty of 0.5% of your unpaid tax per month or partial month, starting the day after the deadline. If you owe $5,000 and pay 30 days late, the penalty is $25 (0.5% × $5,000 × 1 month). The penalty caps at 25% of the unpaid tax, but it can take years to reach that cap.

You also owe interest on the unpaid tax from the deadline date forward. The IRS sets the interest rate quarterly; it is currently around 8% per year but changes based on federal rates. Interest compounds daily and accrues whether you pay one day late or one year late.

If you cannot pay by April 15, you have options. You can request a short-term extension (up to 120 days) by calling the IRS at 1-800-829-1040, which pauses penalties but not interest. You can also set up a payment plan (installment agreement) with the IRS, which allows you to pay in monthly chunks. The IRS charges a setup fee ($31 to $225 depending on the method) and continues to charge interest and penalties until the balance is zero, but the monthly penalty rate drops to 0.25% while you are on a plan.

Paying through your tax software or tax preparer

If you use tax software like TurboTax, H&R Block, or TaxAct, you can pay directly from the filing screen. The software routes your payment through an approved processor and charges a convenience fee. The deadline is still the same—the payment must be submitted by 11:59 p.m. Eastern time on April 15 (or the moved deadline). Do not assume the software will file and pay automatically; you must actively submit both the return and the payment.

If a tax preparer or CPA files your return, ask them whether they will submit your payment for you or whether you need to pay separately. Some preparers include payment submission in their fee; others do not. Clarify this before April 15, because the deadline does not wait for confusion to clear up.

Quarterly estimated tax deadlines and payment

Self-employed people, freelancers, and anyone with income not subject to withholding must pay estimated tax four times per year. The standard dates are April 15, June 17, September 16, and January 15. If any of these dates falls on a weekend or holiday, the deadline moves to the next business day.

You can pay each quarter using the same methods as the annual deadline: EFTPS, Direct Pay, credit card, check, or through tax software. Many people set up automatic quarterly payments through EFTPS or Direct Pay so they do not have to remember each deadline. If you underpay estimated tax, the IRS charges interest and penalties on the shortfall, even if you pay the full amount when you file your annual return in April.

State tax deadlines and payment

Most states follow the federal April 15 deadline for income tax, but some states have different dates or do not have income tax at all. Check your state's tax authority website for the exact deadline. State payments are separate from federal payments and use different systems. Some states accept EFTPS; others require payment through their own portal or by check.

Do not assume a state payment will process the same way as a federal payment. If your state has a different deadline, mark it separately and submit payment through the method your state specifies. Missing a state deadline carries its own penalties and interest, independent of federal consequences.

Frequently Asked Questions

Can I pay my IRS bill after April 15 without a penalty?

No. Any payment after the deadline triggers the failure-to-pay penalty (0.5% per month) and interest. The only way to avoid the penalty is to pay by the deadline or request a short-term extension before April 15. If you have already missed the deadline, you cannot retroactively avoid the penalty, but you can stop it from growing by paying now.

What if I file my return on time but pay late?

Filing on time does not protect you from the failure-to-pay penalty. The penalty is based on when you pay, not when you file. If you file on April 10 but pay on May 10, you owe the penalty for the month of May. File and pay by the same deadline to avoid both penalties.

Does scheduling a payment in advance count as paying on time?

Yes, if you schedule it correctly. With EFTPS or Direct Pay, the payment must be submitted (scheduled) by 11:59 p.m. Eastern time on April 14 to count as on-time for an April 15 deadline. The money does not have to leave your account until April 15, but the scheduling must happen by the deadline.

What if the IRS made an error on my bill?

Pay what you believe you owe by the deadline, then file a claim or dispute with the IRS. Paying stops the failure-to-pay penalty from growing while you resolve the error. If the IRS agrees you overpaid, they will refund the difference plus interest. If you do not pay and the IRS was right, you will owe penalties and interest on top of the original bill.

Can I pay my IRS bill with a credit card if I do not have the cash?

Yes, but the convenience fee (1.87% to 2.35%) is added to your bill. If you charge $10,000, you pay $187 to $235 in fees. You still owe interest and penalties on the original tax if you cannot pay the full amount. Using a credit card to delay payment only increases what you owe.
