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.
