The Downside of 100% Bonus Depreciation: What Advisors Need to Know

Why It Matters

The accelerated deduction boosts cash flow now but can trigger high‑rate taxes on sale, affecting overall investment returns and requiring proactive tax‑planning.

Key Takeaways

• 100% bonus depreciation returns for property placed after Jan 19 2025
• Larger first‑year deductions increase future depreciation recapture tax liability
• Recapture on cost‑segregated assets taxed up to 37% ordinary rates
• Advisors must pair depreciation benefits with exit‑strategy planning (1031, DST, etc.)
• Market slowdown forces owners to sell, making recapture timing critical

Pulse Analysis

The One Big Beautiful Bill Act (OBBBA) represents the most significant tax reduction for real‑estate investors in a generation, reinstating 100% bonus depreciation for qualifying property placed in service after January 19 2025. By allowing the entire cost‑segregated portion of a building—often 20‑30% of the purchase price—to be deducted in the first year, investors can dramatically improve cash flow and accelerate return on equity. For example, a $300,000 cost‑segregation study that previously yielded a $60,000 deduction now eliminates the entire amount, effectively reducing taxable income by the same figure in the acquisition year.

However, the IRS treats these accelerated deductions as temporary, requiring recapture when the asset is sold. Standard building depreciation is recaptured at a maximum 25% rate, but components re‑classified as personal property through cost‑segregation face ordinary‑income recapture rates that can reach 37%. Layered taxes—including capital gains, the 3.8% net investment income tax, and state obligations—can push the effective tax burden on a sale to 30‑40% of the total gain. The article’s apartment‑building example illustrates how $400,000 of prior depreciation can double the tax bill from $260,000 to $550,000.

Given the heightened recapture risk, financial advisors must move beyond the headline deduction and integrate tax‑timing strategies into the client’s exit plan. Options such as traditional 1031 exchanges, Delaware statutory trusts, 721 UPREIT conversions, or Section 453 installment sales can defer or spread the recapture liability, preserving after‑tax returns. The timing is especially critical as the commercial‑real‑estate market remains constrained, with transaction volumes still depressed after the Fed’s rate hikes. Proactive planning ensures that the short‑term benefit of 100% bonus depreciation does not erode long‑term wealth creation.
