A bill for an act relating to local government finances by placing limitations on property tax levy rates.

HF 600 limits property tax increases for Iowa cities and counties. It sets a cap of 102% of a government's average property tax rate over the previous five years for fiscal years starting July 1, 2026. To temporarily exceed this cap for one year within a five-year period, voters must approve with 60% support in a special election. The legislature must also get 60% approval to change these tax limits.
