The Volcker task force on tax reform, part of the President's Economic Recovery Advisory Board, faces a daunting task that is made materially more difficult by ex ante constraints placed on its purview and recommendations. Broad-based reform proposals seem to be out of the question, and distributional constraints appear to eliminate many serious ideas. Nevertheless, I believe that significant tax simplification is feasible despite the task force's constraints, and I will take it as a given that simplification is desirable.
