“AI does your taxes in 5 minutes!” was a marketer’s dream headline.
But this month the IRS issued Bulletin 2025-19 highlighting a 35 % jump in errors from AI-assisted tax platforms. Financial Twitter and LinkedIn lit up; #AITaxFail started trending.
Hot takeaway: Speed is great—until the IRS flags your return and slaps on a 20 % accuracy-related penalty.
Mismatched 1099 income
+28 % YoY increase in CP2000 under-reporter notices (3.2 million in FY 2023 vs 2.5 million in FY 2022).
IRS Data Book 2024, Table 20 “Under-reporter Program – Individual Closures.”
Unsubstantiated R&D credits
39 % of Form 6765 (R&D credit) claims examined in FY 2023 lacked required documentation.

Duplicate dependent claims
IRS issued 1.6 million math-error notices for duplicate or ineligible dependents in FY 2023—an 18 % rise from 1.36 million the prior year.
IRS Data Book 2024, Table 24 “Math Error Notices by Type of Error.”
Schedule C over-deductions
Non-farm sole-proprietor income remains the most error-prone: 55 % net mis-reporting rate (latest Tax Gap Study) with a 6 % climb in dollars under-reported between the 2014-16 and 2017-19 study cycles.

A: 20 % of the understated tax.
Q: Can I amend an AI-filed return?
A: Yes—file Form 1040-X ASAP to reduce penalties and interest.
