I'm also in a non-trivial tax situation, GPT Sol did better than my specialist accountant this year. It needed a lot of steering from me and about 2B tokens, but that is better than spending $3-4k in preparation fees. Total time to prepare and handle steering was still less than I normally spend on tax prep with my accountant.
I think what helped is giving it 100+ pdf and csv documents of my full situation so it knew everything about me and could cross-reference with all my bank statements.
Is it unusual for Americans to spend that much on tax returns?
So, GPT Sol outputted tax return PDFs that you were able to submit to the IRS? (I'd imagine that you couldn't directly e-file like you could from TurboTax.)
Correct, it first did it in a spreadsheet, then filled out 59 pages of returns and supplement forms and I printed and posted it. It also filed my FBAR.
I don't know that I'd trust it with an FBAR given it's an interactive PDF myself, but good to hear that it was able to do it - maybe I'll get fed up doing the FBAR manually one year and trust an agent to do so.
Amazing story!! Honestly, thanks for sharing so completely.
