S 5054: Data Center Tax Accountability and Disclosure Act of 2026

S 5054 in plain English: This bill would require data centers that receive federal tax incentives to publicly disclose certain information, with civil penalties for noncompliance. Violations can result in fines of up to $50,000 per day for general noncompliance and up to $100,000 per day for knowing violations. States would also have an enforcement role under the bill.

Stated purpose

The bill aims to remove a tax break called 'bonus depreciation' for AI data centers and require data center operators to report their electricity and water usage to government agencies or states.

Key points

• Requires data centers receiving federal tax incentives to make public disclosures
• Imposes civil penalties of up to $50,000 per day for general noncompliance
• Imposes civil penalties of up to $100,000 per day for knowing violations
• Allows states to participate in enforcement

Arguments supporters make

• AI data centers consume enormous amounts of electricity and water, and taxpayers should not subsidize that growth through special tax breaks without accountability for environmental impacts.
• Requiring disclosure of energy and water use gives communities and regulators the information they need to plan for strain on local power grids and water supplies.
• The green building exemption rewards data centers that invest in efficiency, encouraging the industry to adopt cleaner, more sustainable practices.

Arguments opponents make

• Removing bonus depreciation raises the cost of building data centers in the U.S., which could push investment and jobs to other countries with more favorable tax treatment.
• Singling out AI data centers for different tax treatment than other large facilities creates an uneven playing field and may slow the development of AI infrastructure.
• Disclosure requirements add regulatory burdens and compliance costs on data center operators, which could be passed on to businesses and consumers who rely on cloud and data services.

Tradeoffs

The bill trades a tax incentive that encourages rapid data center investment for greater government and community oversight of energy and water use; facilities that meet green building standards avoid the tax change, so the burden falls unevenly on operators who have not made those investments.
