Washington

Washington's 2026 Revenue Department report says ESSB 6231 narrowed data-center sales-and-use-tax relief effective July 1, 2026. It ended certificates tied to refurbishment and restricted replacement-equipment benefits. Newly constructed qualifying centers can still seek certificates for eligible equipment; this is not repeal of every data-center exemption.
