- Washington trims data center tax breaks as pressure mounts nationwide
- Lawmakers rethink incentives as AI infrastructure costs keep rising
- Industry pushback slows efforts to reform data center tax policies
The state of Washington has moved to scale back a long-standing tax incentive tied to data center operations, a decision that could reshape how artificial intelligence infrastructure expands in the region.
Governor Bob Ferguson signed SB 6231 into law, narrowing a sales tax exemption that had previously reduced costs for replacing equipment in existing facilities.

Narrowing incentives in a competitive landscape
The rollback focuses specifically on the refurbishment cycle of operational data centers, meaning companies will now face higher costs when upgrading hardware.
New facilities, however, continue to benefit from existing exemptions, which creates a split policy approach that may influence how companies plan future investments.
Historically, sales tax incentives have allowed operators to acquire expensive computing equipment at reduced rates, making it one of the most widely used tools across the US.
No less than 37 states still offer some sort of incentive for data center development, showing how aggressively jurisdictions compete for these capital-intensive projects.
