Limiting annual state spending growth to median worker wage growth, with excess revenues dedicated to property tax relief.

SB 5151 limits annual state spending growth to the average annual increase in Washington's median worker wage, starting in 2026. It requires the state to calculate a spending cap based on the prior decade's median wage growth and directs any excess revenue above this cap toward lowering property tax rates. The bill applies to all state general fund spending and mandates that the Economic and Revenue Forecast Council determine excess revenues by December 1 each year, which the Department of Revenue must use to reduce property tax rates by the following year. This directly affects state budget decisions and homeowners through potential property tax relief.
