AI tax research tools
AI tax research tools answer questions in plain language and point to the code, regulations, rulings or commentary behind the answer. The thing to test is the citations: an answer is only as useful as your ability to check it against the primary source.

Judge a tax research tool by its citations
Language models can state incorrect law fluently. The tax research tools in this directory address that by grounding answers in a defined body of content (the Code, regulations, rulings, cases and, for some, a publisher's editorial analysis) and citing it. The practical test is simple: ask a question you already know the answer to, and click through every citation.
The content behind the tool matters as much as the model. Publisher-backed tools draw on licensed explanations and treatises; others rely on primary sources only. Neither is wrong, but they suit different questions.
