Data Center Tax Accountability and Disclosure Act of 2026

The Data Center Tax Accountability and Disclosure Act of 2026 modifies tax rules and establishes reporting requirements for large data centers. It removes a tax incentive known as bonus depreciation for artificial intelligence data centers unless they meet specific green building standards, such as LEED Platinum or Gold certification. Additionally, the bill requires operators of data centers consuming at least 25 megawatts of power to submit detailed annual reports on their water and electricity usage, emissions, and backup power systems to state or federal agencies. These reports must be made public, and the law prohibits companies from using confidentiality agreements to hide this information. Operators who fail to comply with these reporting requirements face daily civil penalties of up to $100,000 for intentional violations.
