SALTy Citizens: Which State and Local Taxes Contribute to State-to-State Migration?

State and local governments depend heavily on revenue generated from state and local taxes (SALTs). Migration between states occurs for many non-tax reasons, but prior research suggests tax-related factors may play an important role. Even so, the specific SALTs motivating state-to-state migration remain unclear given mixed and inconclusive results of prior studies. This study examines state and local tax variables individually and then jointly, and controls for important economic and noneconomic factors to determine which SALTs matter to residents when making relocation decisions. Using data collected from multiple sources for 2008 to 2015, results indicate overall state and local tax burden, individual income taxes, select sales taxes, and property taxes are all significantly and negatively associated with taxpayer migration. Further, select sales taxes and property taxes seem to be most significantly associated with migration. We also provide some intuition related to the economic impact associated with net migration.
