The TABOR Amendment was approved by voters in 1992. This amendment to the Constitution of the State of Colorado limits the amount of revenue the state can retain. The TABOR limit is equal to the lesser of the prior fiscal year’s revenue limit plus the rate of inflation and population growth in Colorado or the current fiscal year’s revenue. Also, the TABOR Amendment requires voter approval for certain tax increases. For more information about TABOR, visit the Legislative Council TABOR web page.
