relating to tax rates. Providing that the rate of taxes in the state shall not exceed certain annual percentages.

This constitutional amendment (CACR 18) would cap annual increases in New Hampshire state and local government spending and tax rates based on inflation and population growth. Specifically, it limits annual spending increases to a four-year average inflation rate (capped at 2.5%) plus the prior year's population change, with excess revenues up to 10% directed to a rainy day fund. It also grants citizens the right to sue the state or local governments for violations, including recovery of attorney fees and up to 20x those costs if successful. The amendment requires voter approval in the 2026 general election.
