Washington Slashes Data Center Tax Breaks
12 Apr
Summary
- Washington state narrowed sales tax exemption for data center equipment upgrades.
- New facilities still benefit from existing tax exemptions for development.
- Microsoft warned the changes could be anti-competitive and distort competition.

Washington state has enacted changes to its tax incentives for data centers, specifically scaling back a sales tax exemption for equipment replacement in existing facilities. This move, signed into law by Governor Bob Ferguson, introduces increased costs for hardware upgrades.
Despite this adjustment, new data center constructions will continue to benefit from existing exemptions. This bifurcated approach may influence investment decisions, as the sector has historically relied on reduced equipment acquisition costs, with 37 states still offering similar incentives.
Microsoft, a significant operator in Washington, cautioned lawmakers, stating the proposal was "uniquely anti-competitive" and urged for substantial revisions. This action by Washington contributes to a wider trend of reassessing data center subsidies nationwide.
States like Virginia are also grappling with similar decisions on a larger scale. Lawmakers there are considering modifications to tax exemptions that cost billions annually, with some advocating for incentives tied to environmental compliance rather than outright removal.
