Authorizing counties to impose a public utility tax.

HB 1702 would allow Washington counties to impose a 3% tax on utilities (like electricity, gas, water, and sewer services) operating in unincorporated areas. Utilities would add this tax to customer bills and show it separately, while counties must use 0.2% of the revenue for low-income utility assistance. The bill permits counties to exempt business customers (e.g., factories, data centers) but not residential customers unless businesses are also exempt. It defines "utility" broadly to include major service providers and ensures the tax doesn’t overlap with existing state-level utility taxes.
