Warren Targets Big Tech on AI Tax Breaks Amid Scrutiny of Corporate Revenue

Senator Elizabeth Warren is questioning big tech companies about their tax breaks on artificial intelligence (AI) investments, citing a decline in corporate tax payments. In letters to Meta, Alphabet, Amazon, and Microsoft CEOs, Warren and fellow Senate Democrats asked for detailed accounting of the tax deductions and subsidies claimed on AI and data center investments.

The letters were triggered by collective 25% year-over-year drop in corporate tax payments from these four firms, despite rising revenues. Individual figures are striking: Microsoft's federal income tax expense dropped by over $11 billion from fiscal year 2025 to fiscal year 2026, while Amazon's fell nearly $8 billion from FY2024 to FY2025.

The decline in corporate tax payments is linked to the 2025 Republican-led legislation known as the 'one big beautiful bill' act (OBBBA), which included provisions allowing companies to claim generous deductions on capital investments. Warren's office estimates that giants like Alphabet, Amazon, and Microsoft could have saved around $17.9 billion, $15.7 billion, and $12.5 billion respectively through OBBBA-related deductions.

The Warren camp is advocating for the tax savings to be used for essential programs such as SNAP or Medicaid. This isn't Warren's first move on the issue; she previously proposed an excise tax on energy consumption by AI data centers, citing reports of rising consumer electricity bills linked to increasing demand from data centers.
