Just like death and disease, taxes don’t go away just because the economy is bad. In fact, a bad economy is all the more reason for taxpayers to consult an accountant, particularly one who’s skilled in getting refunds for clients.

“We know taxes are unavoidable even during a recession, and most of us need help from an accountant to submit them correctly,” Bierman said. “Accountants’ revenue growth during the recession may have also stemmed from clients who needed their advice to make do with less.”
