Kind of. I first of all did the entire return with it. So we went step by step and yes I fed the forms one at a time. So I filled in 1040 as best I could. Then just asked it what to do next at each step. It helps I've done it before so most of the steps it returned were ones I've done before. However, it did mention several things that I had not heard of, and also some new taxes that I had to file due to some exceptional events last year. So all in all, a solid use case. This year I have an accountant, but it saved my butt this last year, and I will absolutely run through my accountants decisions with it. It has an encyclopedic knowledge and an immense capability to understand without getting tired.
Well my tax situation changed a bit this year, so there were some new taxes I had to file. Additionally it helped with depreciation for real estate. Helped me identify the exact part on the appraisal where I would get the cost of the dwelling (vs the land), and then walked me through the various ways the IRS allows people to do this. Helped me do some tax planning for next year as well around mega backdoor roths. Not lifechanging, but useful.
What's the threat model here? OpenAI gets my social security number and Sam Altman steals my identity? OpenAI leaves an S3 bucket open to the public and my filled out 1040.pdf gets leaked to the world?
Oh no, OpenAI knows how much money I make and they're going to send me ads! Ads that are relevant to my interests. How connivingly evil of them!
People's tax returns are essentially public (yes I know they're not allowed to disclose them). Didn't send the forms in with social security numbers.
This absurd concern for privacy is silly in my opinion. The moment something is submitted to the government it ought to be considered public. Even your social security number is essentially public for anyone who cares to find it.
I would not submit my bank account information to these services, or my passwords, obviously.
Honestly, tax returns should be public again. Would make everyone better behaved IMO. It was this way for most of American income tax history believe it or not.
To be clear, my information has already been part of several breaches anyway. What protects you ultimately is the law not information security. Of course this point is often lost on engineering / computer scientist types who don't understand how law works.
