OpenAI, Thrive Launch Tax AI That Processed 7,000 Returns and Reached 97% Accuracy
2 articles · Updated · OpenAI · May 27
Tax AI processed 7,000 returns across Crete firms in this tax season, automating much of 1040 and 1041 preparation and improving measurably from its first deployment three months earlier.
97% accuracy on drafted returns, about one-third less prep time, and roughly 50% higher throughput came from a Codex-driven loop that turns practitioner corrections and production traces into targeted evals and engineering fixes.
86% of returns reached 75% correct field completion within six weeks, up from 25% at launch, as the system expanded from simpler W-2 and 1099 work into harder K-1s, schedules, and rental-property cases.
OpenAI forward-deployed engineers worked with Thrive and Crete's network of 30-plus accounting firms over six months, using practitioner feedback to identify recurring failures and route only bounded, validated tasks to Codex.
180 hours of tax prep for one senior accountant fell to 15 this year, and Thrive says the same self-improving workflow blueprint is now being applied to bookkeeping, audit, and IT help desk automation.
With AI filing taxes at 97% accuracy, who is legally responsible for the inevitable errors?
