How AI tax filing works with 1040kit

No 150-screen interview. No retyping numbers from your forms.

  1. Drop in your documents

    Put your W-2s, 1099s and last year’s return in one folder. 1040kit reads them on your computer.

  2. Answer a few questions

    It only asks what your documents can’t tell it, like who you support or where you worked from.

  3. Review and file

    See your refund, every deduction and where each number comes from. Then print and mail, or e-file free with IRS Free File Fillable Forms.

AI tax software for W-2 employees and 1099 freelancers

Finding deductions is the main feature, not an upgrade.

If you get a W-2

A simple W-2 return takes a few questions. 1040kit also checks the new deductions you might not know about.

  • No tax on tips, up to $25,000
  • No tax on qualified overtime pay
  • Interest on a new US-assembled car loan
  • The extra deduction for people 65 and older
  • Child Tax Credit and credit for other dependents

If you freelance or drive (1099)

Self-employed filers have the most deductions to find. 1040kit goes looking for them.

  • The 20% qualified business income deduction
  • Home office and business mileage
  • Expenses found in your bank and card statements
  • Self-employed health insurance
  • Personal payments wrongly reported on a 1099-K

Every number on your return shows how it was calculated and which IRS instruction it comes from. The math is done by tested tax code, not by the AI.

Your documents and your return never leave your computer.
