An IRS extension payment is the money you send to the IRS by April 15 when you’re filing for more time to submit your federal return. The extension pushes your filing deadline from April 15, 2026, to October 15, 2026, but it does not push your payment deadline. Anything you owe is still due April 15, and unpaid amounts start collecting interest and a failure-to-pay penalty the next day.1IRS. If You Need More Time to File, Request an Extension
The good news: making the payment is often the same act as requesting the extension. Pay electronically, mark it as an extension payment, and the IRS grants the extension automatically. No separate form needed.2IRS. IRS Reminds Taxpayers an Extension to File Is Not an Extension to Pay Taxes
File vs. Pay: Why the Distinction Matters
A filing extension protects you from the failure-to-file penalty, which is the expensive one at 5% of unpaid tax per month, capped at 25%.3IRS. Failure to File Penalty It does nothing about the failure-to-pay penalty, which runs at 0.5% per month (also capped at 25%) on whatever you still owe after April 15.4IRS. Failure to Pay Penalty Interest accrues on top of both. For the second quarter of 2026, the underpayment interest rate is 6%, compounded daily, and it also runs on the penalties themselves.5IRS. Quarterly Interest Rates
Because both the failure-to-pay penalty and interest are percentages of the unpaid balance, paying any amount by April 15 shrinks the base those charges attach to. The IRS applies payments first to tax, then to penalties, then to interest.6IRS. Tax Topic 653 – IRS Notices and Bills, Penalties, and Interest Charges A partial payment can also help support a later request for penalty relief on reasonable-cause grounds.
How to Make the Payment
IRS Direct Pay
Direct Pay pulls the money straight from a checking or savings account with no fee. On the Direct Pay portal, choose “Extension” as the reason for payment; the system sets the form to 4868 automatically.7IRS. Direct Pay Help You verify your identity with information from a prior return, submit the payment, and get a confirmation number. Save it. The IRS cannot look it up for you later.8IRS. Pay Personal Taxes From Your Bank Account
Credit Card, Debit Card, or Digital Wallet
Card and digital wallet payments (PayPal, Venmo, Click to Pay) go through two IRS-approved processors, Pay1040 and ACI Payments, Inc. Personal debit cards carry a flat fee of $2.10 to $2.15. Credit cards run 1.75% to 1.85% of the payment, with a $2.50 minimum. None of that fee goes to the IRS.9IRS. Pay Your Taxes by Debit or Credit Card Select the extension payment type during checkout and the payment doubles as your Form 4868 filing.
Electronic Funds Withdrawal With Tax Software
If you e-file Form 4868 through tax software, you can authorize an Electronic Funds Withdrawal (EFW) in the same session. Enter your bank routing and account numbers, pick a debit date on or before April 15, and Treasury pulls the funds on that date.10IRS. Pay Taxes by Electronic Funds Withdrawal Once the extension is accepted, you can’t edit the payment. To cancel, call IRS e-file Payment Services at 888-353-4537 at least two business days before the scheduled debit.
Paper Form 4868
Mailing a paper Form 4868 with a check or money order still works. The form asks for your estimated total tax (line 24 of Form 1040), estimated payments already made (line 33), and the balance you’re paying now.11IRS. Form 4868, Application for Automatic Extension of Time to File It has to be postmarked by April 15.
EFTPS
The Electronic Federal Tax Payment System is free, but as of October 2025 individuals can no longer create new EFTPS accounts. Existing individual users may continue for now, with a full transition to Direct Pay or the IRS Online Account expected by September 2026.12IRS. EFTPS – The Electronic Federal Tax Payment System Businesses can still enroll. EFTPS payments have to be scheduled by 8:00 p.m. ET the day before the due date to count as timely.13EFTPS.

How Much to Send
The IRS wants a good-faith estimate of your total tax liability, paid in whole or in part by April 15.14IRS. Tax Topic 304 – Extensions of Time to File Your Tax Return An extension can be invalidated if the number wasn’t a reasonable attempt. Start with last year’s return, then adjust for changes to income, withholding, deductions, and credits this year. Form 4868 walks the math: expected total tax on line 4, expected payments on line 5, balance due on line 6.
If you expect a refund, you generally don’t need to pay anything with the extension, and no penalties or interest apply when nothing is owed.15IRS. About Form 4868 The trap is guessing wrong. If your final return shows a balance, penalties and interest run from April 15, not from the day you discovered the shortfall.
If You Can’t Pay in Full
File the extension anyway. That still eliminates the 5%-per-month failure-to-file penalty. Pay whatever you can toward the balance, then arrange the rest.
Short-Term Payment Plan
Available to individuals owing under $100,000 in combined tax, penalties, and interest. Up to 180 days to pay in full, no setup fee, but penalties and interest keep accruing until the balance clears.16IRS. Payment Plans – Installment Agreements
Long-Term Installment Agreement
For individuals owing $50,000 or less who have filed all required returns. Setup fees range from $22 (direct debit, applied online) to $178 (non-direct-debit, applied by phone or mail). Low-income taxpayers may qualify for a waiver or reimbursement.17IRS. Online Payment Agreement Application Both plans can be set up through the IRS Online Account. Once a plan is in place, the failure-to-pay rate drops from 0.5% to 0.25% per month.4IRS. Failure to Pay Penalty
Penalty Relief
If you filed an extension but couldn’t pay on time, First Time Abate is often the quickest path to relief. It’s an administrative waiver available if you filed the same type of return for the prior three years without penalties.18IRS. Administrative Penalty Relief Reasonable-cause relief is the alternative, for situations such as serious illness, natural disaster, or other events outside your control.19IRS. Penalty Relief for Reasonable Cause Call the number on your notice or file Form 843. When a penalty is reduced, the interest tied to it is adjusted too.
Verifying the Payment
Direct Pay gives you a confirmation number at the end of the transaction. Two business days after the scheduled payment date, check your bank statement or log into your IRS Online Account. If the payment shows “Pending” in your IRS account, give it three more business days before assuming a problem.7IRS. Direct Pay Help EFTPS issues an EFT Acknowledgment Number as a receipt. EFW debits typically show on bank statements as “IRS USA Tax Payment” or similar.10IRS. Pay Taxes by Electronic Funds Withdrawal
Situations Where the Rules Shift
Living Abroad
If you live and work outside the United States and Puerto Rico on April 15, you get an automatic two-month extension to file, until June 15, without requesting one; attach a statement explaining your situation. Interest still runs from April 15 on any unpaid tax.20IRS. U.S. Citizens and Resident Aliens Abroad – Automatic 2-Month Extension Filing Form 4868 before June 15 extends the filing deadline to October 15.
Combat Zone Service
Armed Forces members serving in a designated combat zone or contingency operation get an extension equal to their time in the zone plus 180 days. This one covers both filing and paying, and no penalties or interest accrue during the extension period. Qualifying support personnel and spouses are generally covered as well.21IRS. Extension of Deadlines – Combat Zone Service
Federally Declared Disaster Areas
Taxpayers in areas covered by a federal disaster declaration may get postponed filing and payment deadlines set by the IRS. Recent examples: taxpayers hit by severe storms in Washington state (December 2025) have until May 1, 2026, and those affected by Winter Storm Fern in Tennessee (January 2026) have until May 22, 2026.22IRS. IRS Tax Relief for Washington Storm Victims23IRS. IRS Tax Relief for Winter Storm Fern in Tennessee The current list of covered areas is at IRS.gov/disaster.24IRS. Tax Relief in Disaster Situations
Businesses
Corporations, partnerships, and S-corporations use Form 7004 instead of Form 4868 for an automatic six-month extension. A separate 7004 is required for each return. As with individuals, the extension does not extend the time to pay. Corporations can avoid the late-payment penalty if the amount paid by the original due date is at least 90% of the total tax on the final return and the rest is paid by the extended deadline.25IRS. Instructions for Form 7004
State Taxes
Federal and state extensions are separate. Some states grant automatic filing extensions; some accept the federal extension only when no state tax is owed; some require their own form. Nine states have no income tax at all. Whatever the state’s filing rule, an extension to file almost never extends the state payment deadline. If you owe state tax, expect it to be due April 15.1IRS. If You Need More Time to File, Request an Extension
Missing the Extended Deadline
If October 15 comes and goes without a return, the failure-to-file penalty kicks in at 5% per month of the unpaid balance, running alongside the failure-to-pay penalty and interest that have been accruing since April.3IRS.
