The Index has been published yearly since 2003. It ranks states based on the taxes that matter most to businesses and business investment: corporate tax, individual income tax, sales tax, unemployment tax and property tax. The states are scored on these taxes, and the scores are weighted based on the relative importance or impact of the tax to a business.
