I used it last year and renewed again this year. I had one client who received a letter from state taxing agency disallowing her charitable contributions, which were, in part, related to a large carryover from 2022 (I didn't use PP in 2022). The client also happened to be a good friend so I used her as a test case. Turned everything over to PP. They communicated directly with my client and sent me copies of all correspondence along the way so I was kept in the loop. It was a very positive experience and the matter was resolved in favor of my client.
I did raise my fees by $20 last year to cover the cost. We explained the benefits to each of our clients at pickup and almost no one complained about the increase - only 2 or 3 out of about 700 clients.
