The tax code has always changed frequently, so nothing new there. (Remember the year the ACA was introduced, the same year the expense/capitalization requirements were changed? For experienced tax pros, that was almost like starting over again.) Preparer requirements have bounced around a lot too. I think what has kept me engaged is that I have always worked for a firm, never self-employed. No worries about E&O insurance, ordering supplies, IT security, etc. Of course I pitched in with some of the tasks of running a business, but for the most part I was able to focus on tax research and preparation, planning--you know, the skills we acquired to enter this business in the first place. I like taking courses (an academic at heart), so required CEs were never a burden. The biggest complaint I can think of is the long hours during tax season, which repeat as Oct 15 comes around.
That said, I have finally retired! Time to have some fun and read more books. I will eventually volunteer for VITA or AARP, but first I want to get organized around the house and do some things I always wanted to do. I will depend on this board to keep me in the loop so my tax knowledge doesn't fall by the wayside.
