Senate Democrats Press Meta on Using Research Credits for AI Data Centers

Seven Democrats on the Senate Finance Committee asked Meta Platforms to justify claiming the federal research tax credit on its AI data center buildout, a credit Meta says cut its federal tax bill by $6.6 billion from 2023 to 2025, according to the letter.

In an Oct. 13 letter to Chief Executive Mark Zuckerberg, Ron Wyden of Oregon, the committee's top Democrat, and Senators Sheldon Whitehouse, Elizabeth Warren, Catherine Cortez Masto, Maggie Hassan, Ben Ray Luján and Peter Welch cited reports that Meta had told the Internal Revenue Service its AI data centers are experimental "pilot models" that qualify for the credit.

That position, the senators wrote, would be "in violation of the spirit and, potentially, the letter of the tax law." They added: "Subsidizing your A.I. data center build is not close to meeting this standard."

The letter draws on Meta's own disclosures: $700 million of research credit in 2023, about $2 billion in 2024 and nearly $4 billion in 2025.

Using Joint Committee on Taxation figures that put the credit's total cost at $32 billion in 2025, the senators said Meta alone would account for more than 10% of all research credits claimed in the U.S.

Separately, on Oct. 7, Welch asked the IRS for a list of every company that claimed the research credit for AI data center costs from 2020 to 2025, the value of each claim, and whether the agency will issue guidance to confine the credit to its intended use.

They asked whether Meta claimed Section 41 credits for building and running AI data centers in 2023 through 2025, whether it described those sites to the IRS as pilot models, and whether it treats AI data centers differently from its other data centers for credit purposes. If it does, they want the legal analysis.

For each year, they asked how much of the credit related to AI data centers, and specifically how much went to microchips, computing equipment and other materials needed to build or operate them. They also asked whether EY or other accounting or law firms advised on the position, and requested copies of any opinions. They asked for answers by Oct. 31.

The letter also reopens an older dispute. The senators asked why Meta treated $4.1 billion of Zuckerberg's 2008–2010 stock-based compensation as a qualified research expense, a position it took in 2013, and whether it will keep contesting the $355 million in back taxes the IRS is seeking on that claim.

Two separate positions are at issue. The data center claim covers hardware the senators describe as "widespread and relies on proven technology," which would not normally qualify. The older claim treats Zuckerberg's stock compensation as a research expense, a dispute Meta is still contesting.

Meta's latest annual report lists research-credit documentation among its uncertain tax positions. The letter carries no subpoena behind it. Under federal tax-privacy law, Section 6103(f), only the chairman of the Finance Committee, not its top Democrat, can require the Treasury to hand over a company's returns, and the committee may see them only in closed session unless the taxpayer consents. The minority can request documents, publicize answers and press the IRS, but it cannot compel Meta to answer by the Oct. 31 deadline.

If chips and computing equipment in AI facilities count as qualified research supplies, the credit lowers the after-tax cost of that spending. Meta's 2025 annual report says it books research-credit benefits only when it judges them more likely than not to survive examination.

An IRS challenge would turn on whether the facilities are experimental or established infrastructure.
