January 1, 2026, marks the beginning of a new chapter in the tax code. Whatever emerged from the legislative process—full TCJA extension, partial extension with modifications, or complete sunset—the 2026 tax year brings changes that every business owner needs to understand. This post provides a practical overview of what changed and what business owners should do differently.
Individual Income Tax Rates
The individual income tax rate structure for 2026 is the most fundamental change affecting business owners. If the TCJA rates were extended, the seven-bracket structure continues with the top rate at 37%. If the TCJA expired, the rate structure reverts to pre-2018 law with a top rate of 39.6%. The brackets are also affected—and the rate at which specific income levels are taxed may have changed even if the top rate remained the same. Business owners should update their income projections and tax models with the new rate structure immediately.[1]
Pass-Through Business Income
The fate of the Section 199A qualified business income deduction is critical for pass-through business owners. If the deduction was extended, eligible business owners continue to deduct up to 20% of their qualified business income. If it expired, the full amount of pass-through business income is taxed at the individual rates—a significant increase in the effective tax rate for most pass-through business owners. This change alone may warrant a reconsideration of entity structure for businesses that had relied on the 199A deduction.[2]
Estate and Gift Tax
The applicable exclusion amount for 2026 determines the estate planning landscape for the year. If the enhanced exemption was extended, estate planning continues at the elevated levels. If it reverted to approximately $7 million per person, a significantly larger number of estates are now subject to the federal estate tax. The annual gift tax exclusion continues to be adjusted for inflation separately from the lifetime exemption.[3]
SALT Deduction
The $10,000 cap on state and local tax deductions was one of the most politically contentious TCJA provisions. If the cap was extended (with or without modification), the PTET election remains an important planning tool. If the cap expired and the full SALT deduction was restored, the PTET election becomes less critical—though it may still provide benefits in certain situations.[4]
What to Do Now
Business owners should take immediate action to update withholding and estimated tax payments based on the new rates, review and update payroll tax calculations for employees, evaluate whether entity structure changes are warranted, schedule a planning session with their tax advisor to model the impact of the changes on their specific situation, and review any expiring elections or provisions that need to be renewed or modified for the new year.[5]
