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.
Who is protected: Oregon taxpayers and utility ratepayers
