A quiet change in Washington tax law will make server replacements taxable for data center operators starting next year.
Most Washington business owners have never heard of the data center equipment sales tax exemption—and that's exactly why they should pay attention now. Washington State is eliminating a longstanding tax break that has allowed data center operators to purchase replacement servers without paying sales tax. Starting July 1, 2026, that exemption disappears, and any business that relies on data center services or operates one could face new costs.
Senate Bill 6231, signed into law, strikes the "replacement server equipment" definition and exemption from Washington's sales tax code. The change is in Section 2 of the bill, which amends RCW 82.08.986, subsection (8)(h)(iii).
In plain terms: data center operators—including small qualifying businesses and tenants who lease data center space—previously could buy replacement servers tax-free. Starting July 1, 2026, they will owe Washington's full sales tax on those purchases.
This isn't just about large data center companies. The exemption applied to qualifying small businesses and tenants operating within data centers, too. If your professional services firm relies on hosted servers or cloud infrastructure housed in a Washington data center, or if you operate your own server infrastructure, this change could eventually show up in your costs—either directly through higher equipment purchases or indirectly through price increases from your hosting provider.
For data center operators themselves, the impact is more immediate. Server replacement is an ongoing operational necessity, not a one-time purchase. Losing the tax exemption means a recurring cost increase every time equipment needs to be refreshed or upgraded.
The effective date is July 1, 2026 (Sections 2 and 3, page 23 of the bill). That gives data center operators and their tenants roughly 18 months to understand the impact and plan accordingly. Some businesses may want to accelerate equipment purchases before the deadline to avoid the new tax; others may need to budget for higher ongoing costs.
Tax exemptions often go unnoticed until they're gone. Because this exemption has been in place for years, many operators may not have factored in the cost of replacing it. The change is also buried in a bill focused on broader data center tax policy, which is why it's easy to miss.
If you operate a data center, lease space in one, or manage IT infrastructure that depends on hosted servers in Washington, now is the time to review your equipment replacement schedules and budget assumptions. Talk with your accountant or tax advisor about whether accelerating purchases before July 1, 2026, makes sense for your situation.
