Meta faces Senate deadline over data center tax credits after Treasury benefit cut its tax rate

Meta reported a 2% effective tax rate for the first nine months of 2026, helped by an $8.03 billion benefit from Treasury Notice 2026-7 tied to corporate alternative minimum tax relief. Senators have given the company a week to explain why it treated AI data centers as experimental for research tax credits. Meta says the data centers require genuine experimentation.
Meta's nine-month 2026 tax provision was $1.03 billion on $53.5 billion of pretax income, producing a 2% effective rate. Treasury Notice 2026-7 generated an $8.03 billion benefit, partly offsetting a $15.93 billion third-quarter 2025 charge tied to the One Big Beautiful Bill Act.
Seven senators asked Zuckerberg by Oct. 31 to explain IRS filings that reportedly treated AI data centers as experimental pilot models eligible for the research credit. The letter cites claimed federal tax reductions of $6.6 billion from 2023 through 2025. Meta's unrecognized tax benefits reached $20.82 billion by Sept. 30.
The dispute could affect how aggressively technology firms claim research credits for AI infrastructure, potentially shifting tax costs among Meta, its shareholders, and the broader public. If Congress or the IRS narrows eligibility, companies may reconsider data-center accounting and spending, while taxpayers may gain or lose depending on whether credits are deemed legitimate. The outcome may also shape public trust in how large firms use tax incentives for AI expansion.
