UF's tax program is good, but to be honest, the kids in the program, well, are a bit nerdy.
At least the ones I know are.
2 things we can establish: if you want to practice tax law, you will (eventually) need to get the LLM- though you don't have to do it right after the JD.
2) if you don't go to a well-regarded program, it's probably not worth your time.
If I were you, I'd actually do a year or two of the JD and try a federal tax class before I jumped head over heels into a school based on its tax or other specialty graduate programs. Go to the best JD school you get into and worry about tax llm's once you get your first grades back, since you might reevaluate your plans if you get a C in tax, bankruptcy, etc, and A's in property-
