We had been doing taxes the old fashioned way….pencil and paper and the old forms. We switched to the tax professional for ONE year and it was so bad he gave us a break on his fee because we owed so much. The next year we used Turbo Tax and with nearly identical salary and deductions, we got a large refund.
Go figure.
Not sure what that guy did to mess up, but we were young and stupid then and didn’t go over his prep work with a fine tooth comb.
