Data Center Tax Breaks Face Repeal

A growing movement across the United States is seeing state governments repeal or place moratoriums on long-standing sales tax exemptions for data centers. This legislative shift could reshape the financial landscape for firms attempting to scale their AI compute capacity, potentially raising equipment costs for new or planned infrastructure projects by upwards of 7%.

The momentum behind these policy reversals appears linked to revised assessments of tax revenue losses. Discrepancies between initial projections and actual outcomes have prompted officials to re-examine the economic benefits provided to the data center industry.

Legislative Shifts Across State Lines

In Ohio, the state government moved to repeal its tax exemptions for data centers in June 2026. This decision followed revelations from Ohio Governor Mike DeWine regarding the scale of the financial impact. According to reports, the state determined that its lost tax revenue reached $1.6 billion, significantly exceeding the earlier projection of $136 million.

Other states have since initiated their own restrictive measures. Since July, Illinois and Arizona have paused their respective exemption programs. The program in Illinois has been suspended indefinitely, while Arizona has implemented a 3-year moratorium on its own tax relief provisions.

Expanding Scope of Legislative Review

The movement extends well beyond the states that have already enacted changes. Currently, a further nine states are evaluating the possibility of halting their existing exemptions. Additionally, 28 states have introduced legislative bills aimed at limiting the scope or effects of current data center tax incentive programs.

The financial impact of these changes is tied directly to local sales tax rates. According to Avalra data, the sales tax in Ohio is approximately 6%, with Illinois recording a figure just above that level. These percentages represent the immediate increase in equipment procurement costs for new data center builds, though some projects currently under construction may remain protected by existing agreements.

Industry and Economic Context

The expansion of AI capacity has placed unprecedented demand on energy grids and physical infrastructure. While companies seek to build more facilities, the rise in construction costs is occurring alongside concerns about grid capacity and energy pricing. Reports indicate that big tech firms have significant liabilities tied to infrastructure expansion.

Research attributed to Nikkei suggests that large technology companies have accumulated approximately $1.65 trillion in off-balance-sheet debt through contracts with data center operators. This figure has reportedly grown eightfold over the last four years, existing alongside visible balance sheet debt totaling $1.35 trillion.

Implications for Future Infrastructure

The potential removal of tax incentives creates a complex decision-making environment for firms planning large-scale deployments. As states move to reclaim tax revenue, the cost-benefit analysis for building new high-compute facilities becomes increasingly sensitive to regional tax policy.

While firms often prioritize proximity to power and fiber, the financial burden of a 7% increase in hardware acquisition costs may redirect future investment toward jurisdictions that choose to maintain or implement new tax exemptions. Those states that sustain these incentives could see an increase in project applications as firms seek to mitigate the rising expenses associated with modernizing their infrastructure.
