Federal tax software that files extensions
Any software that e-files Form 4868 will get you an extension. The real choice is which one you want to finish your return with.
Reviewed October 30, 2026 against IRS.gov guidance. How we check facts.
Start with the free option
If you only need the extension, IRS Free File e-files Form 4868 at no cost for anyone. You can choose different software later for the return itself.
What to compare
- Extension support: does it e-file Form 4868, and Form 7004 if you have a business?
- Your situation: self-employment, rental property, investments and multiple states push you into higher editions.
- Total price: federal plus state fees, and whether the price changes closer to the deadline.
- Help: access to a tax professional, and audit support if you want it.
- Importing: last year’s return and W-2 or 1099 import save time and reduce errors.
