Basically this. For tax, and law in general, LLMs are prone to giving the wrong answer for anything specific (though they're great at the super general stuff because they're just restating one of the millions of summaries written by humans).

Gemini still isn't sure what details are in the version of OBBA that actually passed, because there was more discussion about various proposals (that didn't make it into the bill) than there was about the final version of the bill itself.

Unfortunately, it's an intractable problem based on the ways that LLMs work. In order to overcome those limitations, you have to provide so much detail to the prompt that you would find the answer faster searching manually.
