I take a two day class every year which generates 14 hours of CPE credits which are certified. Have attended this class starting in 1999 and all years since. In fact, class is week after next. I also attempt to attend Webinars which are offered by ATX and the IRS. These will also certify credits if you want. In addition, I subscribe to and USE Quickfinder Individual, Business and All States. I also use the US Master Tax Guide and the Wisconsin Tax Guide as well as the textbooks that are included in the schooling. In addition, I use Pub 17 as well as a working relationship with the local IRS service office. I am consistent with reading the questions and answers on this board and use the "Search" or question option for issues that I need additional help with. I don't have a problem with being licensed by the IRS. Of course, nobody likes to pay a fee every year, but if it will help keep down some of the preparer error that I see cross my desk, I will not complain (too much)! I have held a PTIN since the first year they came out, which, of course, means nothing other than that I have tried to keep current with the times. The classes I attend are not inexpensive and not always interesting, but I think they are necessary to what I do. I hope this answers your question from my perspective as to what some of us unlicensed preparers do to comply.
