What we support, by tax year
The IRS approves software one form and one tax year at a time, so being approved for last year says nothing about this year. Find your form, read across to your tax year, and this says where we stand.
As of November 3, 2026. For our test results against the IRS, see E-file Status.

Every form, every tax year
- Approved
- The IRS has approved Gideon Tax to e-file this form for this tax year.
- Coming

- Corrects, Claims or Names the year

- Not supported
- We do not e-file this form for this tax year.
