The Taxpayer Bill of Rights (TABOR) is a controversial constitutional amendment passed in 1992 in Colorado. The measure was sponsored by Douglas Bruce, a Republican state senator. TABOR requires that voter approval be obtained before any tax increase or new fee can be enacted, and limits the amount of state spending to the previous year's revenue plus inflation.
