States that once competed aggressively to attract data centers with lucrative tax incentives are increasingly reconsidering those policies as the AI boom drives unprecedented growth in the industry. For more than a decade, states offered sales tax exemptions, property tax abatements and other incentives to lure major investments from technology companies including Amazon, Microsoft, Meta and Google. Policymakers argued that data centers would create construction jobs, generate tax revenue and establish states as hubs for the growing digital economy.
But the arrival of generative AI has dramatically increased demand for data centers, causing the value of many incentive programs to far exceed original projections. At the same time, concerns about electricity demand, water consumption, grid infrastructure costs and lost tax revenue have sparked political opposition from lawmakers and local communities. Several states have now moved to pause, narrow or eliminate tax incentives that were once considered essential economic development tools.
Arizona lawmakers have introduced several bills that would repeal tax breaks for data centers. The state currently offers transaction privilege and use tax exemptions for qualifying data center equipment. Senate Bills 1463 and 1467, along with House Bill 2820, would eliminate those incentives by repealing the state's data center certification program.
The proposals have been introduced, but haven’t become law yet. Georgia lawmakers are considering ending a tax exemption for equipment used in qualifying high-technology data centers. Senate Bill 410 would stop the state from issuing new exemption certificates while preserving benefits already granted.
State fiscal analysts estimated that ending new exemptions could significantly increase state and local tax revenue. Illinois paused incentives for new data center developments after Governor JB Pritzker announced a two-year suspension beginning July 1, 2026. The state previously used its Data Center Investment Program to attract facilities through a range of tax exemptions tied to investment and job creation requirements.
Pritzker said the pause would allow Illinois to study the industry's impact on energy demand, water use, and electricity costs. Michigan currently provides sales and use tax exemptions for qualifying data center equipment, but some lawmakers want to end those incentives. House Bill 5396 would eliminate the sales tax exemption, while House Bill 5398 would make related changes to property tax treatment.
