A recent article from Pew Charitable Trusts shows how routine evaluations can help states make tangible improvements to their tax incentives. According to Pew, 30 states now have laws requiring evaluation of the incentives, and recent examinations in several states included key components that helped to inform the results. When analyses started with an effort to determine the specific goals of each incentive, their effectiveness was more easily determined. High-quality evaluations also measured economic impact. For instance, Rhode Island’s evaluation of the Motion Picture Production Tax Credit showed that revenue gained would never match the cost of the program.
