AI tax software in the United States

The deepest market in the world for tax AI — consumer filing, self-employment, sales tax, and firm automation all at scale.

41companies
23AI features added
18AI-native

The US supports more AI tax products than every other market combined, for structural reasons: a self-assessment system, roughly 70 million self-employed and gig workers, and a sales tax regime fragmented across thousands of jurisdictions. Each of those creates a distinct software category.

Consumer filing is a duopoly with AI layered on — Intuit Assist in TurboTax, AI Tax Assist in H&R Block — while the genuinely AI-native companies cluster in self-employment (Keeper, FlyFin, Lettuce), sales tax (Kintsugi, Numeral, Anrok), and firm automation (Black Ore, Filed, Aiwyn).

Frequently asked

What is the best AI tax software in the US?
It depends on the return. W-2 filers are served by the mainstream products and their AI assistants; 1099 and gig workers get more value from year-round deduction tracking like Keeper or FlyFin; businesses with multi-state sales need indirect tax automation, which is a different category entirely.
Can AI file a US federal tax return with the IRS?
Yes — several AI-driven products hold IRS e-file authorisation, including Instead and the Column Tax engine now inside Aiwyn. Authorisation covers transmission; the accuracy of the return remains the filer's responsibility.
