Over two decades have passed since Colorado voters adopted The Taxpayer’s Bill of Rights in 1992. TABOR allows government spending to grow each year at the rate of inflation-plus-population. Government can increase faster whenever voters consent. Likewise, tax rates can be increased whenever voters consent. This Issue Paper analyzes TABOR’s effect on state government spending and taxes by examining three decades: The 1983-92 pre-TABOR decade; the first decade of TABOR, 1993-2002; and the second decade, 2003-12. The final decade included the largest tax increase in Colorado history, enacted as Referendum C in 2005. Decade-2 was also marked by increasing efforts to evade TABOR by defining nearly 60% of the state budget as “exempt” from TABOR.
Tax-and-Spending Limitation Results
The Taxpayer’s Bill of Rights Amendment has worked well to achieve its stated intention to “slow government growth.” Although government has still continued to grow significantly faster than the rate of population-plus-inflation, the Taxpayer’s Bill of Rights did partially dampen excess government growth. It did not cut or reduce reasonable government growth.
In terms of economic vitality, Colorado’s Decade-1 was best for Colorado. Unlike in the pre-TABOR decade, or in TABOR Decade-2 with its record increase in taxes and spending, because of Referendum C, Colorado’s first TABOR decade saw the state economy far outperform the national economy.
