• The 2025 Republican tax bill extends and enhances corporate tax breaks, including bonus depreciation through 2029, keeping the corporate rate at 21%.
  • Major companies like AT&T (T), T-Mobile (TMUS), and energy firms project billions in tax savings, with some expecting to pay little or no federal income tax.
  • Federal corporate tax receipts have dropped roughly 15% year-over-year, contributing to deficit concerns amid political debate over equity and growth.

Congressional Republicans have advanced a 2025 tax bill that deepens corporate-friendly provisions from the 2017 Tax Cuts and Jobs Act, with the Trump administration framing it as the second major phase of their tax policy. According to people familiar with the matter, the legislation, often called the “One Big, Beautiful Bill,” aims to fulfill campaign promises by extending historic tax cuts for businesses.

Efforts to restructure corporate tax obligations have hit a snag for federal revenue, with a recent analysis by the Congressional Budget Office and outside tax groups showing a roughly 15% year-over-year drop in federal corporate income tax receipts—about $77 billion—attributed largely to the new provisions. “It’s a no tax rate type of environment through 2028,” one executive from an energy firm said, describing the impact of bonus depreciation and weakened corporate minimum tax rules.

Without these extensions, many companies would face higher tax burdens as TCJA provisions began to phase out. The bill keeps the corporate income tax rate at 21%, eases international tax rules like the Base Erosion and Anti-Abuse Tax by canceling a scheduled rate increase, and increases Section 179 expensing limits for small businesses. Treasury communications blame “liberal states” for resisting implementation, while supporters emphasize growth and competitiveness for job creators.

Several large companies have publicly reported substantial expected tax savings. AT&T anticipates $1.5–$2 billion lower cash taxes in 2025, while T-Mobile projects about $1.5 billion per year in cuts. In the energy sector, OneOK (OKE) expects $1.5 billion in savings, and firms like Devon Energy (DVN) and Targa Resources (TRGP) report they will no longer be subject to the Corporate Alternative Minimum Tax, pushing rates into the mid-single digits. MGM Resorts (MGM) stated it expects to pay no corporate income tax this year and instead receive a $100 million refund, partly due to bonus depreciation.

Capital-intensive sectors such as telecom, defense, and energy benefit disproportionately, as full expensing allows firms to deduct the full cost of equipment and technology upfront, reducing the cost of capital. Lockheed Martin (LMT) reports roughly $0.5 billion in cash tax savings, largely from immediate expensing of R&D. However, the package has drawn criticism from left-leaning organizations like the Center for American Progress, which argue it disproportionately benefits high-income households and large corporations, worsening inequality.

The political context is heated, with Democrats highlighting the regressive distribution of benefits and potential cuts to social spending implied by higher deficits. International relations add friction, as the U.S. maintains a more generous corporate tax environment than many global partners, conflicting with efforts like the OECD’s “Pillar Two” minimum tax. Market reactions have been muted so far, but analysts note that after-tax cash flow and reported earnings are rising for affected firms.

Looking ahead, if provisions remain in place, experts warn of higher federal debt and continued political pressure for future reforms. Fiscal policy researchers caution that the package prioritizes corporate tax relief over fiscal sustainability, while pro-business economists counter that a low-tax destination is essential for growth and on-shoring investment. The debate echoes post-2017 TCJA controversies, with renewed scrutiny on who truly benefits from corporate tax cuts.
