Mar 6, 2026 Real Estate Tax Incentives and Planning Strategies Under the One Big Beautiful Bill Act (OBBBA)

The One Big Beautiful Bill Act (OBBBA), enacted July 4, 2025, significantly reshapes real estate tax planning by accelerating deductions while narrowing energy incentives. The Act permanently restores 100% bonus depreciation under §168(k), allowing immediate expensing of qualified property, including assets identified through cost segregation studies. New §168(n) enables full expensing of qualifying portions of newly constructed nonresidential buildings used in manufacturing and production, creating major benefits for industrial and logistics projects. OBBBA also permanently restructures the Opportunity Zone program with rolling 10‑year designation cycles and enhanced rural incentives, including a 30% basis step‑up through Qualified Rural Opportunity Funds. §179 expensing limits increase to $2.5 million, further supporting capital investment. At the same time, OBBBA accelerates the sunset of key energy credits, making careful timing and proactive planning between 2025 and 2031 essential to maximize tax benefits and after‑tax cash flow....
