Overview
- A growing group of states including Arizona, Pennsylvania, Illinois, Ohio and Texas have this month paused, narrowed or repealed sales‑tax exemptions for data‑center equipment after audits and budget reviews.
- Industry estimates and reporting put the added upfront cost for new projects at roughly 7% or more because equipment that was once tax‑exempt will now face state sales taxes.
- Ohio’s disclosure that exemptions cost the state about $1.6 billion helped trigger the wave of rollbacks as lawmakers questioned why ratepayers should fund transmission, substations and generation for private compute campuses.
- Companies building AI and crypto capacity are reassessing site choices and project economics while some projects already under contract may remain grandfathered under older deals.
- Federal and state regulators are now considering rules to force developers to pay for grid upgrades and to site new generation, a shift that could slow builds, raise power prices for residents, and reshape where infrastructure is built.
