TI Public, TI Pro and TI Expert
Every tier answers from the same Federal Tax Authority material and passes the same checks before an answer is shown: every citation must resolve to a provision TI holds, every rate it states must appear in the sources it read, and an answer in the wrong language is not shown. The tiers differ in the AI that writes the answer and in how much you can ask.

TI is research, not tax advice. It finds the provision that decides a question and explains what it says; the judgement, and any filing, stay with you or your tax professional.
