The Taxpayer's Bill of Rights: Evidence From Colorado and Implications for Arizona

For those interested in one of the most extreme state tax and expenditure limitations, TABOR – Colorado’s initiative that limits the funding of most expenditures to annual revenue growth restrained by the sum of annual population growth and inflation rates – would seem to be exactly the right choice. To some, the initiative simply limits government to spend within its means. However, the analysis in this paper reveals that, true to the language in the 1992 Colorado initiative, TABOR limits government growth, and over time the public sector, as a share of the overall economy, declines sharply – crowding out opportunities for investments in strategic initiatives or opportunities for tax reform that may be popular with large voter constituencies or the business community. Advocates point out that provisions in TABOR do allow for voter overrides, but these are costly in both time and money, and until the overrides take place, government is
hamstrung. A simpler, more efficient alternative would be to elect fiscally conservative legislators and hold them accountable for prudent fiscal decisions that strike the right balance between a tax base conductive to economic growth and strategic investments that provide public sector infrastructure, nurturing the business climate and promoting the health and well-being of the citizenry. The paper first outlines the TABOR amendment in Colorado and examines its fiscal consequences for that state. It then examines the potential impact of a TABOR in Arizona.
