Seal of Wisconsin Wisconsin

Wisconsin has a statutory limit on tax revenues under Wisconsin Statutes 13.085. Enacted in 2011, the statute requires tax increases to be approved by 2/3 supermajority in either house of the Wisconsin Legislature. This statute can be overridden in the case of a voter-approved tax increase only if the referendum sent to voters is passed by a joint-resolution of both houses in the Wisconsin Legislature.

 
The base year represents the year the hypothetical Taxpayer's Bill of Rights (TABOR) would have been enacted. Selecting a base year changes how the state’s TABOR is calculated because the annual growth rates of inflation and population change depending on when TABOR is enacted.
