Rob’s New Book on the Colorado Taxpayer’s Bill of Rights (TABOR)
House Bill 1187: Why should state government get to spend more just because people work more?

Increasing state spending as population grows assumes that larger populations require more government services. This may not always be the case, but it at least refrains from taxing people simply because they work harder.

Two Decades of Colorado’s Taxpayer’s Bill of Rights (TABOR)

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.

TABOR Benefits Colorado’s Citizens: A response to misleading Video
In 2005 the Center on Budget and Policy Priorities (CBPP) released a video to help defeat proposed measures like Colorado’s Taxpayer’s Bill of Rights (TABOR) in other states. Voters in several states are considering such measures in 2006, including Maine, Montana, Nebraska, Nevada, and Oregon. The CBPP video’s message is that TABOR devastates the economy and the ability of government to fund schools, roads and health care. By understanding the truth, however, viewers will note that they have nothing to fear from passing their own TABOR. Unfortunately, they may not recognize the CBPP video for the highly misleading propaganda piece that it is.
