From Policy to Planning: What the Latest One Big Beautiful Bill Changes Mean

The OBBB introduces several changes to tax policy that impact both businesses and individuals. Here, we outline the key updates and planning strategies, as discussed during a panel discussion held on September 25, 2025, with experts from Lumsden McCormick and Bond, Schoeneck & King.
Key Changes Affecting Businesses
Depreciation Updates
- Section 179 Deduction: The limit is increased to $2.5 million, with a phaseout threshold raised to $4 million. These limits will adjust for inflation and apply to property placed in service after 12/31/24.
- Bonus Depreciation: 100% bonus depreciation is permanently reinstated for qualified property acquired and placed in service after 1/19/25. Previously, bonus depreciation was scheduled to phase out.
- Qualified Production Property (QPP): A new category for non-residential real property used in manufacturing, production, or refining, eligible for 100% bonus depreciation. This incentivizes investment and may attract outside capital or buyers.
Research & Experimental Expenditures (Section 174)
- Domestic R&E: Immediate expensing returns for U.S. costs after 2024, reversing mandatory capitalization rules from recent years.
- Foreign R&E: Mandatory capitalization and amortization over 15 years remain.
- Deduction Options: Both large and small businesses can expense unamortized costs from prior years, split deductions between 2025 and 2026, or continue amortization.
Qualified Business Income (QBI) Deduction
- The 20% QBI deduction is made permanent, with expanded phase-in ranges and a new minimum deduction for qualifying taxpayers. This benefits owners of pass-through entities and reduces tax burdens in asset sales.
Passthrough Entity Tax (PTET) Deduction
- PTET deduction remains available, despite changes to state and local tax itemized deductions.
Qualified Small Business Stock
- Gain exclusion for qualified stock is increased, with up to 100% exclusion for stock held five years and higher limits indexed to inflation.

- New reporting requirements for employers and payors, with transition relief for 2025.
- Individuals in tipped industries can deduct up to $25,000 in qualified tips; similar deductions apply for overtime pay.
