The benefits and costs of changing the state tax code can now be estimated by a dynamic computer program, developed for the Foundation by the Beacon Hill Institute. Texas-STAMP provides highly detailed information about the effects of specific tax changes on various aspects of the state economy over a five year period. Accessed over the Internet, Texas-STAMP will be used in the halls of the Capitol as legislators debate tax proposals, such as increases in the sales tax, property tax reduction and the introduction of a business activity tax. Texas-STAMP is the centerpiece of the multi-faceted, comprehensive research initiative on school finance that the Foundation began in 2003.
