Oregon HB 4084 — Temporary Suspension of Data Center Property-Tax Exemption
Oregon · Oregon HB 4084 (2026 Leg. Session, eff. June 5, 2026)
Oregon House Bill 4084, effective June 5, 2026, temporarily suspends the state's property-tax exemption for qualifying data centers — a program that had offered facilities up to 15 years of tax relief to attract investment. The suspension halts new applications while the legislature evaluates whether the incentive is still in the public interest given rapid data center growth and grid strain concerns.
Technical detail
HB 4084 suspends Oregon's data center property-tax exemption program (ORS ch. 285C) for new applicants effective June 5, 2026, pending legislative review of program benefits vs. costs; existing approved exemptions are grandfathered.
Who is protected: Oregon taxpayers and utility ratepayers
Who must comply: Data center developers seeking new Oregon property-tax exemption certificates
