GPT-6 Astra tax review turns a $117,360 bill into a $191,173 refund
The author had Astra spend 90 minutes checking every tax form line against source documents and produce a 15-page report; after the accountant confirmed each point, the conclusion flipped, a $308,533 swing.
I just got the draft of my 2025 tax return - it says I owe $117,360 of tax. On top of what I already paid. Oof. But it didn't feel right to me. I asked ChatGPT Astra to do a secondary review, ticking and tying every number to source documents. Max effort. It ran for 90 minutes. Output - a 15 page report. It says I'm actually due a $191,173 REFUND. I reviewed Astra's work line by line with my accountant. He agreed, the LLM is correct. I was about to send Uncle Sam $117,360. Instead, I'm getting back $191,173. That's a swing of $308,533 (!!!!!!) The LLM couldn't have done my tax return from scratch - I still need my accountant. But for massively complex detail oriented work, and LLM is the best thought partner you can have. Connect a frontier LLM to your email and file storage, then ask it to review your past tax returns. You never know what it might find. My prompt is in the next tweet.
