Authorizing funding tools to mitigate the impact of sales tax sourcing in certain cities that host industrial and warehousing industries.

SB 5518 authorizes cities with over 120,000 residents in high-population counties (≥1.5 million) and at least 25% industrial/warehousing zoning to impose a new 0.3% sales tax. The tax, collected by the state at no cost to the city, must be used to improve community vitality in areas negatively impacted by sales tax sourcing laws. Cities must hold public meetings, maintain a budget transparency webpage, and conduct surveys before implementing the tax, which can only begin after July 1, 2025, and last up to 20 years. This bill directly affects specific industrial/warehousing communities near Seattle/Tacoma ports, aiming to offset fiscal challenges from existing tax structures.
