Clients Buying Businesses Should Consider Cost Segregation

Why It Matters

Early integration of cost segregation and QPP into transaction planning can unlock immediate cash flow and prevent loss of tax value, directly impacting deal economics and after‑tax returns.

Key Takeaways

• Cost segregation converts years of depreciation into immediate cash flow
• 100% bonus depreciation applies to assets placed after Jan 19 2025
• Allocation language in purchase agreements limits post‑close cost segregation
• QPP provides an extra 100% deduction for qualified production property
• Early depreciation planning preserves tax value and avoids filing errors

Pulse Analysis

Depreciation has become a decisive lever in M&A due diligence, especially as the tax code now permits 100% bonus depreciation for qualifying assets placed in service after January 19, 2025. Cost segregation, an engineering‑driven analysis, reclassifies portions of a building—such as specialty electrical, plumbing, or decorative finishes—into shorter recovery periods, turning multi‑decade deductions into a near‑term cash‑flow event. This shift means that buyers who overlook depreciation planning risk leaving substantial value on the table, while those who model it early can significantly boost after‑tax returns.

The contractual side of a deal is equally critical. Allocation schedules reported on Form 8594 lock in the tax characterization of assets, and courts have upheld these allocations, as seen in the Peco Foods decision. Consequently, any cost‑segregation study must work within the framework set by the purchase agreement; it cannot retroactively rewrite asset classifications. Practitioners should ask three diligence questions: whether the transaction triggers §1060 reporting, if allocation language restricts component‑level analysis, and whether the property presents a viable shortcut or immediate expensing opportunity under current law.

For manufacturers and other production‑oriented buyers, the Qualified Production Property (QPP) provision adds another layer of opportunity. QPP offers a temporary 100% special depreciation allowance for qualifying non‑residential real property, provided strict timing, use, and election rules are met. Missteps—such as missing the construction start window or failing to designate the integral production portion—can nullify the benefit. Proper filing of Form 3115 for method changes and timely bonus‑depreciation elections are essential to capture these incentives. By embedding depreciation strategy into the transaction timeline, advisors safeguard tax value and enhance deal economics.
