The 2025 Tax Act – Key Business Tax Provisions
One key change for business taxpayers under the 2025 Tax Act concerns the tax treatment of “domestic research or experimental expenditures” (often also referred to as “U.S. R&D” costs). Also, the 2025 Tax Act permanently enacts into law the provision from the Tax Cuts and Jobs Act of 2017 that created the “qualified business income” deduction – generally allowing a 20% deduction with respect to the “qualified business income” from partnerships, S corporations, and sole proprietorships.
