Summary of the Simulation Results of BHI's State Tax Analysis Modeling Program (STAMP)

The following tables present findings of tax model simulations estimated using seven of the 15 STAMPs that are currently in use. For each state we used STAMP to simulate the effects of a one percent increase in both the income and sales tax rates. The tables here show the effects of those simulation on tax revenues, employment and the capital stock in each state. Since there is currently no income tax in Texas, STAMP cannot accurately address the implications of such a policy change. Therefore, you will see n/a for the income tax change simulation for that state. At the bottom of each table you will see an average, weighted by population, of the results of the simulation in all the states presented.
