The Cheapest Way to File a Tax Extension (2026)

An honest look at what an IRS extension actually costs across the main providers — including the free options for a simple personal return. For business (7004) and nonprofit (8868) extensions, GrantExtension is among the cheapest full-service filers at a flat $9.95, with Form 4868 just $4.95.

The honest answer for a simple personal 1040: the cheapest option can be free. IRS Free File, IRS Direct Pay (paying estimated tax and selecting "extension" counts as a filed 4868 — no form needed), and TurboTax Easy Extension all file a basic Form 4868 at $0. We'd rather tell you that than pretend otherwise. Where we win is business and nonprofit extensions — which those free options don't cover — and an easier, faster experience across all three forms.

Figures from our 2026 competitive analysis. "n/a" = form not offered. EZExtension's flat $9.99 is confirmed; most other paid prices marked TODO(verify) could not be confirmed to the dollar and tiered providers (TaxExtension.com) vary by plan. Free options (IRS Free File, IRS Direct Pay, TurboTax) cover the simple 4868 only. Always confirm current pricing on each provider's site before relying on it.

How to pick the cheapest option

  • Simple personal 1040, comfortable with IRS tools? Free File or Direct Pay can extend you for $0. If you'd rather have a guided flow and instant confirmation, our Form 4868 is $4.95.
  • Business return (7004)? No free IRS option exists. We file it for a flat $9.95 — at or below the cheap-tier floor and well under premium filers.
  • Nonprofit (8868)? Several cheap filers skip 8868 entirely (the $9.99 price leader doesn't offer it). We file it for a flat $9.95.

Why GrantExtension is the easiest cheap option

  • Transparent flat pricing — one fee shown before you pay, no tiers or per-credit math.
  • All three federal forms (4868, 7004, 8868) in one clean, mobile-first flow.
  • About a 5-minute filing with instant IRS e-file and email confirmation.
  • We never store your sensitive tax data after the extension is filed.
  • Money-back guarantee if the IRS rejects a return we can't fix.
