My brother is a retired CPA/ partner at E&Y who volunteers each year to do taxes for the elderly. I received the following from him this morning:
"For a few years I've volunteered to do tax returns at a nearby library (last year Las Vegas beckoned so I took a year off). Anyway, we get "retrained" every year using IRS materials, including sample problems. The IRS provides answers. so you can check if you did the work correctly. It turns out that every IRS answer is incorrect. Your tax dollars at work"
