# Corporate Tax Revenue Declines Amidst Record Profits and Policy Shifts Over 100 major firms paid zero federal income tax despite record-breaking corporate earnings. - **Source:** [Fortune | FORTUNE](https://brifing.si/source/769282ef-327a-4454-909a-3c7936216004) - **Published:** 2026-10-30 - **Topic:** [Finance](https://brifing.si/c/finance) - **Original article:** - **On Brifing:** https://brifing.si/s/b9c6fc67-5bf4-43ca-9d2b-515cde3f9c2b ## Corporate Tax Revenue Plummets Federal corporate income tax revenue dropped by approximately 15%, totaling $381 billion for the fiscal year ending September 30. This decline follows a broader 25% reduction since 2024. While corporate profits reached a record $4.7 trillion in mid-2026, the effective tax rate for over 700 profitable corporations averaged only 10.4%. ## Zero Tax Liability Firms A report identified 114 companies, including Tesla, Walt Disney, United Airlines, and DoorDash, that paid no current federal income taxes last year. These findings rely on SEC financial filings rather than IRS data. While these zero-tax firms draw attention, experts suggest they represent a smaller fiscal impact than companies paying reduced rates. ## Concentration of Tax Avoidance Matt Gardner of ITEP argues that the primary threat to federal revenue is not zero-tax companies, but the hundreds of corporations paying significantly less than the 21% statutory rate. These 706 companies collectively saved $198 billion in taxes last year, creating a substantial hole in the federal government’s capacity to function. ## Impact of OBBBA Legislation The One Big Beautiful Bill Act extended the 21% corporate tax rate and made several breaks permanent. Notably, it introduced immediate expensing for domestic R&D and 100% bonus depreciation for property acquired after January 2025. These provisions are projected to add $3.4 trillion to the federal deficit over the next decade. ## Tech Giants and R&D Credits Alphabet, Microsoft, Amazon, and Meta saved a collective $46 billion using R&D and depreciation incentives. Meta specifically faces scrutiny from seven senators regarding the classification of AI data centers as experimental pilot models. The company maintains these investments are essential for innovation, citing over $200 billion spent on R&D since 2021. ## Congressional Inquiry into Meta A group of senators, including Ron Wyden and Elizabeth Warren, demanded answers from Mark Zuckerberg by October 31 regarding Meta’s tax credit claims. They argue that subsidizing AI infrastructure does not meet the standard for research innovation. Meta contends that AI-optimized data centers require unique, non-simulatable testing that justifies these specific tax incentives. ## Debate Over Economic Strategy Policy experts remain divided on the efficacy of corporate tax hikes. Proponents argue higher taxes reduce the deficit and interest rates. Conversely, critics like Adam Michel of the Cato Institute suggest that R&D credits, supported since 1981, are essential for maintaining global competitiveness and incentivizing the capital investments necessary for long-term growth. ## Future Fiscal Outlook The current tax landscape appears to be the new normal under existing permanent legislation. Unless a future Congress or administration reverses these policies, companies will likely continue leveraging depreciation and R&D bonuses. The sustainability of this model remains a central point of contention in ongoing debates regarding the federal deficit. ## Sources covering this story - https://fortune.com/2026/10/30/which-us-corporations-getting-tax-breaks-are-biggest-threat-us-federal-deficit/ — --- _Summary written by Brifing from the original reporting.
