Cost Segregation and Your Operating Agreement: Timing Matters

Roger Ledbetter, CPA · 2026-02-14 · 4 min read

A cost segregation study accelerates depreciation deductions by reclassifying components of a building into shorter recovery periods. It is one of the most valuable tax tools in real estate. But the timing of the study and the structure of the operating agreement's allocation provisions determine who actually benefits from those accelerated deductions.

What Is Cost Segregation?

A cost segregation study identifies components of a building that qualify for shorter depreciation lives. Items like electrical systems, plumbing, flooring, and site improvements can be reclassified from 39-year or 27.5-year property into 5, 7, or 15-year property. This front-loads the depreciation deductions into earlier years.

The result is larger deductions in the first few years of ownership, which reduces taxable income and can create losses that flow through to partners on their K-1s.

How Does the Operating Agreement Affect Cost Segregation?

The cost segregation study generates deductions. The operating agreement determines who receives them. Three provisions in the operating agreement directly interact with cost segregation results.

The allocation method. Under Safe Harbor allocations, the accelerated depreciation deductions are allocated based on the ratios in the operating agreement. Under Target Capital, they flow based on the hypothetical liquidation analysis. The method determines which partners receive the benefit.

Nonrecourse deduction allocations. Most cost segregation deductions in a leveraged real estate deal are nonrecourse deductions, because the property is financed with nonrecourse debt. The operating agreement should specify how nonrecourse deductions are allocated among the partners.

Loss limitation provisions. If the accelerated deductions create losses that would push a partner's capital account negative, the qualified income offset or deficit restoration obligation provisions determine whether and how those losses can be allocated.

Why Does Timing Matter?

The timing of the cost segregation study relative to partner admissions and the operating agreement's effective provisions can change the result.

If the study is completed in the first year of the partnership, the full benefit of the reclassified depreciation flows through the allocation provisions from the start. If the study is completed in a later year, the accelerated deductions are allocated based on who has positive capital account balances and how recourse and nonrecourse debt is allocated among the partners at that point. Partner capital accounts and debt allocations can shift over the life of a deal, so the timing of the study directly affects which partners absorb the tax benefit.

Additionally, if partners are admitted at different times during the deal, the operating agreement's provisions for allocating depreciation to newly admitted partners determine whether they receive a share of the accelerated deductions.

What Should You Coordinate?

If your partnership is considering a cost segregation study, coordinate three things:

Review the allocation provisions in the operating agreement to confirm how depreciation deductions will be allocated. Make sure the allocation method supports the intended distribution of tax benefits.

Confirm the debt structure. Since most cost segregation deductions are tied to nonrecourse-financed property, the partners' ability to use those deductions depends on their share of nonrecourse debt allocations.

Timing of the study. When the study is completed affects which partners can absorb the accelerated deductions. The deductions flow to partners based on who has positive capital account balances and how recourse and nonrecourse debt is allocated at the time the deductions are recorded. Completing the study at a different point in the deal can shift which partners receive the benefit.
