State Tax Incentive Evaluations Database

Source: National Conference of State Legislatures, October 31, 2016

State tax incentives continue to be on state legislative agendas and more and more lawmakers have expressed interest in having good information on the impact of incentives. As a result, states across the country are starting to gather data and use evidence to systematically evaluate tax incentives.
To illustrate what sort of evaluations states are conducting, NCSL, with the generous support of The Pew Charitable Trusts, created a database of state tax incentive evaluations. Evaluations published since the start of 2008 are included and more reports will be added over time.
