Founder says Grok found tax errors in four years of returns

Jason Freedman says he gave Grok 266 unlabeled tax and financial files and asked it to check four years of returns his CPA had prepared.

Freedman says Grok found errors including missed mortgage interest, double-counted HSA contributions, and a missing IRA form. He says Grok also reviewed the CPA's amended return over several versions before he was ready to sign it. The account comes from a post on X by Elon Musk that repeats Freedman's claims. The post does not include the returns or the amended filings, so the errors and their tax effect are unverified.
