Meta cut nearly $4 billion from its 2025 tax bill by treating AI data centres as experimental models under a federal research credit, Anadolu reported on 30 September. The company told the Internal Revenue Service that the facilities were a “giant experiment that could fail”, according to the report, which drew on four people familiar with Meta’s operations. The tax authority could overturn the savings, according to a separate account of the company’s filings.
Key points
- Meta treated AI data centres as pilot models and Nvidia chips used in them as experimental supplies.
- The New York Times reported that the research-credit strategy saved Meta $3.9 billion in taxes in 2025.
- Meta’s filings acknowledge that the IRS could overturn the tax savings.
- Senate Democrats have separately sought information about AI infrastructure deductions under a 2025 tax law.
Meta’s pilot models and Nvidia chips
The Research & Experimentation Tax Credit was introduced in 1981 to encourage innovation and domestic competitiveness. It allows credits for supplies used in research rather than ordinary business operations. Meta’s treatment of its facilities places the question of what counts as research at the centre of a large infrastructure tax claim: the buildings and equipment serve the company’s AI work, while the company classifies them as part of an experiment.
That classification extended to processors purchased from Nvidia. People familiar with the matter said Meta began treating commercially proven chips as experimental supplies when they were used in AI facilities, according to Anadolu. Their established commercial use is material to the dispute over the credit: Meta’s position turns on the role the chips play inside its facilities, rather than on whether the processors themselves are new.
The New York Times put the savings from declaring the data centres “pilot models” at $2 billion in 2024 and $3.9 billion in 2025. It said Meta’s filings acknowledged that the IRS could reverse the savings because of “uncertainties with our research tax credits”. That leaves the tax authority with a consequential decision about costs Meta has already treated as eligible.
Meta’s tax payments and research spending
In 2025, Meta’s federal income tax payment was $2.8 billion, against $9.6 billion in 2024, with profits roughly unchanged, CNBC reported. Those payments cover the company’s overall federal income tax position. The reported research-credit savings concern one part of that position, so the change in payments should not be attributed in full to the classification of data centres.
Meta defended its use of the credit by pointing to what it said was $200 billion invested in research over five years, including $57 billion in 2025. “Like other companies that invest at this scale, we use the tax incentives Congress established decades ago to encourage this type of domestic investment,” the company said, according to Anadolu. Its defence rests on the scale and purpose of its spending. The IRS question concerns whether the particular facilities and supplies claimed meet the requirements of the research credit.
Warren’s separate inquiry into 2025 deductions
A separate congressional inquiry concerns tax deductions authorised under legislation passed in 2025. Senator Elizabeth Warren and five other senators sent letters to the chief executives of Meta, Amazon, Alphabet and Microsoft seeking details of deductions related to AI and data centres, as well as lobbying before the law passed, CNBC reported on 28 September. Those questions concern a different tax measure from the research credit behind Meta’s reported pilot-model claims.
In their letter to Meta chief executive Mark Zuckerberg, the senators cited $72 billion in company capital expenditure in 2025. They described the “vast majority” as data centre construction and other AI spending, and said much of it might have qualified for immediate deduction under the 2025 law. The figure describes investment potentially affected by that law, not the amount of research credit Meta claimed.
The senators also raised a broader budget concern. Warren’s letter cited a 25 percent decline in corporate tax payments in 2026 amid rising revenue, according to CNBC. The Congressional Budget Office projected in February that federal corporate income tax receipts would fall from $452 billion to $404 billion in 2026. Those figures give the inquiry a fiscal setting, although the senators’ request asks each company for its own deductions and tax payments.
Amazon is due to respond to the senators by 12 October, Yahoo Finance reported.
