A TABOR, or Taxpayer's Bill of Rights, is a law designed to limit the size of government. Under a TABOR, a state government's revenue and spending are not allowed to exceed a defined limit, and any revenue in excess of the limit must be refunded to taxpayers.

This online tool allows you to see how a spending cap could have limited the size of your state's government. A TABOR limit is defined in terms of spending in a particular base year, with allowances for growth proportional to parameters such as inflation and state population. You can also select a spending limit based on state gross domestic product (GDP).

To begin, select your state, pick a base year, and choose how you want the spending limit to grow over time. You can pick inflation only, inflation plus population, and state GDP, with the option of adding a certain additional percentage to annual inflation. You may also choose to have the spending limit apply to state governments only, or both state and local governments.
