EasyTaxUSA Tax Extension

Running behind on your taxes? Form 4868 gives you six more months to file your federal return, no reason required, and with EasyTaxUSA, requesting it is free: we prepare and e-file the form for you. The extension keeps you clear of one of the costliest penalties the IRS charges, 5% of your unpaid tax for every month your return is late, up to 25%. It does not give you more time to pay, so estimate what you owe, pay what you can by April 15, and request the extension by the same date. If you already extended your 2025 return, your deadline is October 15, 2026: sign in and we’ll help you finish today. The window to request a 2025 extension closed on April 15, 2026, so if you didn’t extend, the fastest fix is to file now. Planning ahead? 2026 returns and extension requests are due April 15, 2027, and you can file that extension free with us.

Estimate What You Owe

Round up what you have: W-2s, 1099s, and last year’s return. The IRS only asks for a reasonable estimate, not a perfect one, and if nothing big changed last year’s tax is a sensible floor; our free tax calculator makes it a quick job.

Pay What You Can by April 15

An extension doesn’t move the payment deadline, so pay at least 90% of your total tax by April 15 (through withholding, estimated payments, or a payment made to the IRS when you request your extension) and the rest with your return by October 15, and the IRS waives the late-payment penalty for the extension period. If you can’t reach 90%, pay as much as you can to limit both interest and the penalty.

Request the Extension by the Deadline

Enter your estimate by April 15 and we prepare and e-file Form 4868 for you, free. We send you the IRS acknowledgment; keep it with your records as proof the request went through. Any tax you owe is paid directly to the IRS: pay online at IRS.gov in minutes and choose “Extension” as the reason so it’s matched to your Form 4868. If you’d rather skip the form, the IRS also treats that online payment marked as an extension as the request on its own, or you can mail a paper Form 4868 postmarked by April 15. Either way, come back whenever your paperwork is ready, and by October 15 at the latest, and we help you finish the return itself.

Finish & E-File by October 15

Come back when your paperwork is complete and let our software check every credit and deduction. When you file with us, enter the extension payment you made to the IRS in April and we apply it to your balance; filing earlier gets any refund sooner, and filing by October 15 keeps you clear of the late-filing penalty.

What an Extension Does and Doesn’t Do

  • Six more months to file your federal return, to October 15, with no reason required and no approval letter
  • Protection from the late-filing penalty of 5% of unpaid tax per month, as long as you file by the extended date
  • Leaves the payment deadline where it is: tax is still due April 15 (June 15 if you’re living or serving outside the U.S.; see the FAQ), with interest and the late-payment penalty on any unpaid balance
  • Extends the time to file a federal gift tax return (Form 709) for the same year, but not the time to pay any gift tax
  • Moves your three-year refund window with it, to October 15, 2029 for a 2025 refund
  • Keeps the April 15 deadline for traditional and Roth IRA contributions and quarterly estimated payments (SEP-IRA contributions do get the extra time)
  • Covers your federal return only; your state may honor it, require its own form, or have no income tax
  • Has no effect on your audit risk; when you file is not an audit factor

Important Dates for Tax Extensions

Two seasons overlap right now. If you extended your 2025 return, your deadline is October 15, 2026. If you’re thinking about next year, 2026 returns follow the same pattern one year later. Every deadline listed below falls on a weekday, so no weekend or holiday roll-forward applies to them.

  1. April 15, 2026 2025 returns and any tax owed were due. Last day to request an extension for a 2025 return; that window has closed.
  2. June 15, 2026 Automatic two-month deadline to file and pay for U.S. citizens and residents out of the country, and their last day to file Form 4868 (line 8 checked) to extend to October 15.
  3. October 15, 2026 Extended deadline for 2025 returns. Last day to file on time if you requested an extension. Late returns can still be e-filed until the IRS closes e-file for the year.
  4. December 15, 2026 Discretionary extra two months for taxpayers out of the country who wrote to the IRS by October 15 and were not denied.
  5. Late January 2027 IRS e-file for 2026 returns expected to open. From then until April 15, you can e-file your return or request an extension.
  6. April 15, 2027 2026 returns and any tax owed are due. Last day to request an extension for a 2026 return.
  7. October 15, 2027 Extended deadline for 2026 returns.
  8. October 15, 2029 Last day to claim a 2025 refund if you filed a timely extension. Without one, the window closes April 17, 2029 (April 15 is a Sunday that year and April 16 is a DC holiday, so the deadline moves to the next business day).

If the 15th falls on a Saturday, Sunday, or legal holiday, the deadline moves to the next business day. The 2027 dates follow the IRS’s standard rules (returns due April 15, six-month extensions to October 15) and will be confirmed when the IRS releases the 2026 Form 4868. Taxpayers in federally declared disaster areas may have later dates.

Frequently Asked Questions About Tax Extensions

No, and this is the costliest misunderstanding out there. Form 4868 extends the time to file your return by six months; the tax itself is still due on the April deadline (April 15, 2026 for 2025 returns, April 15, 2027 for 2026 returns). Interest runs on the unpaid balance from April 15, and the late-payment penalty of 0.5% per month applies unless you’ve paid at least 90% of your total tax by the deadline. You can still get the extension without paying a cent, but pay as much as you can by April 15 to keep those charges small.
