On October 13, 2026, seven Democratic members of the U.S. Senate Committee on Finance sent Meta Platforms CEO Mark Zuckerberg a letter asking whether Meta claimed federal research credits for building or operating AI data centers. The senators cite $6.6 billion in total research credits for 2023–2025, while saying the share tied to AI data centers remains unclear. They requested answers by October 31. The letter identifies the credit as one under Section 41 of the Internal Revenue Code.
The letter is distinct from a Senate report announced October 9 on data-center companies’ job data, power costs, equipment tax incentives and confidentiality agreements, covered in NeoTeo’s earlier report.
What the $6.6 billion covers
The $6.6 billion is the overall research-credit total that the senators say Meta reported for the three tax years. The letter gives these annual amounts:
| Tax year | Overall research credits attributed to Meta in the letter |
| 2023 | $700 million |
| 2024 | Approximately $2 billion |
| 2025 | Approximately $3.9 billion |
The senators describe the credits as amounts Meta used to reduce its federal income-tax liability. The letter does not assign a specific portion of the $6.6 billion to AI data centers, chips or other related equipment.
What the senators want Meta to explain
The senators ask what legal rationale and expenses supported any Section 41 claims for AI data-center construction or operation. They also ask whether Meta treated AI and non-AI data centers differently, and how much of the claimed expenses involved chips, computing equipment and other materials.
The letter asks about reports that Meta may have characterized AI data centers as experimental “pilot models” for the credit. It also asks whether Meta sought advice from accounting or law firms, including Ernst & Young, or received written opinions. These are questions for the company; the letter does not say that any firm advised Meta.
The senators argue that the research credit is intended for experimental work with a high degree of technical uncertainty, rather than standard business operations or technologies already in commercial use. They describe the reported data-center tax position as potentially contrary to tax law. The letter also cites Meta’s annual-report disclosure of uncertainty about whether its documentation would sufficiently substantiate the activities behind its research credits.
