...I used to spend hours reading regulations, once I found the one I wanted/needed, on the various taxing jurisdictions websites. No more do I have to do that!!! I pull TTR up and presto bingo I have an answer. AND, as a bonus, if I don't understand the plain English of the answer, I can always reach out to the wonderful people at TTR and ask for more clarification. Can't do that on a state's website, and calling them can take hours. I always receive and answer back very quickly from TTR. Your team understands that I need answers timely, and they know what they are doing.
