Big Tech Erases $32 Billion in Taxes by Expensing the AI Data Center Boom

Four letters sent Sunday night↗ by Senator Elizabeth Warren laid bare the accounting behind the artificial intelligence buildout ¹. Addressed to the chief executives of Meta, Alphabet, Amazon, and Microsoft, the inquiry demands an accounting of corporate tax payments that cratered as the tech giants poured tens of billions of dollars into data centers ¹².

The inquiry comes five weeks before the 2026 midterm elections, with voters in competitive congressional districts increasingly furious over surging power bills tied to utility infrastructure upgrades ¹⁵.

Vanishing corporate taxes under the 2025 tax bill

Under the 2025 One Big Beautiful Bill Act, Republican lawmakers enacted permanent 100 percent bonus depreciation and restored immediate research expensing↗ ²³. Those rules let companies immediately write off capital spending against current profits rather than depreciating equipment over its useful lifespan ³⁴.

Hyperscalers seized the mechanism ⁴. By frontloading deductions on physical infrastructure, the four technology giants erased roughly $32 billion in corporate income tax obligations across their latest annual reporting periods ¹².

Four companies, four different tax yardsticks

Crucially, the cited letters aggregate mismatched accounting metrics across different corporate fiscal years rather than standard apples-to-apples figures ¹². In fiscal 2026, Microsoft's current federal income tax expense dropped by more than $11 billion, plunging from $14.1 billion to $2.5 billion ¹⁴. Amazon's cash federal income tax payment fell by nearly $8 billion from fiscal 2024 to 2025 ¹. Alphabet's combined current federal and state tax expense fell by more than $7 billion over that same stretch ¹. For Meta, its calendar-year federal income tax bill shrank from $9.6 billion in 2024 to $2.8 billion in 2025, even as net earnings held steady and capital expenditures reached $72 billion ¹.

The public absorbs the utility costs

While corporate tax collections are down 25 percent nationwide this year↗ and the Congressional Budget Office projects federal corporate receipts to tumble from $452 billion to $404 billion, households carry the burden of grid expansion ¹⁴. Across the United States, average electricity rates climbed 27 percent between 2019 and late 2025 to 19 cents per kilowatt-hour↗, driven by 700 gigawatts of data center interconnection requests ⁵.

Each of the four hyperscalers contributed $1 million to Donald Trump's inauguration and spent millions lobbying Congress ahead of the 2025 legislation ¹. The White House defends the deductions as pro-growth provisions driving job creation ¹. Yet the Institute on Taxation and Economic Policy↗ found that the five largest technology companies paid an effective federal tax rate of just 4.5 percent on $422 billion in collective profits last year, claiming $27 billion in accelerated depreciation breaks alone ³.

Capitol Hill clashes over ratepayer relief

The clash has gridlocked Capitol Hill ⁶. The House passed the bipartisan Ratepayer Protection Act in a 417 to 3 vote↗ to establish federal standards directing state regulators to assign grid upgrade costs to 100-megawatt loads ⁵⁶.

However, Senator Martin Heinrich blocked expedited Senate approval, calling the measure toothless because it only requires state utility commissions to consider the standards rather than enforcing mandatory developer cost absorption ⁵⁶.

The targeted technology companies have until 12 October 2026 to answer Warren's demands regarding their deductions and lobbying records ¹. For investors and utility customers, those disclosures will determine whether Big Tech retains its taxpayer-funded runway or faces an aggressive legislative rollback when Congress reconvenes after November ²⁶.
