State lawmakers seeking to make residential property taxes more affordable have two broad options: across-the-board tax cuts for taxpayers at all income levels, such as a homestead exemption or a tax cap, and targeted tax breaks that are given only to particular groups of low- and middle-income taxpayers. One such targeted program to reduce property taxes is called a “circuit breaker” because it protects taxpayers from a property tax “overload” just like an electric circuit breaker: when a property tax bill exceeds a certain percentage of a taxpayer’s income, the circuit breaker reduces property taxes in excess of this “overload” level. This policy brief surveys the advantages and disadvantages of the circuit breaker approach to reducing property taxes.
