What is cost segregation?

A cost segregation study analyses what a building is made of and assigns parts of its depreciable cost to the recovery periods that apply to them. Instead of depreciating the entire non-land basis of a residential rental over 27.5 years, components that qualify as personal property or land improvements may be recovered over shorter periods, which moves depreciation deductions earlier. It changes the timing of deductions, not the total amount of basis. The recovery periods are set out in IRS Publication 946.

How much can a cost segregation study save on a Miami property?

There is no reliable general figure. The result depends on the property's actual components and basis, the land allocation, the year placed in service, the depreciation rules in force for that year, the owner's tax situation — including whether passive-activity limits apply — and how long the property is held. Any projection should come from a CPA working with the study provider for that specific property; a percentage quoted without those inputs is not a basis for a decision.

Is a study worth it for a smaller property?

It depends on the numbers, not on a threshold. The cost of a study is weighed against the present value of earlier deductions the owner can actually use, the expected holding period and the recapture that may apply on sale. A CPA can model that trade-off for the specific property before a study is commissioned.

Does cost segregation change FIRPTA for a foreign owner?

It does not change whether FIRPTA withholding applies on a sale by a foreign person, but accelerated depreciation can increase the gain and recapture reported on the eventual tax return. Withholding rates, exceptions and withholding certificates are described on the IRS FIRPTA withholding page; a cross-border tax adviser should estimate the actual tax before closing.

Can a study be done after the property was bought?

Often, yes. When a study is completed for a property already in service, the change is commonly implemented as a change in accounting method, which can involve filing Form 3115. Whether that route is available and how it is applied is a question for your CPA.

How does Javier fit into this?

On the real estate side: helping an investor evaluate the property, its condition, its documents and its purchase terms, and making sure the investor's CPA has the information needed — such as the closing statement and building details — early enough to plan. See his Miami buying advisory.

Q: Who performs a cost segregation study?

Qualified study providers — commonly firms combining engineering or construction-cost expertise with tax knowledge — working with the owner's CPA. The IRS Cost Segregation Audit Techniques Guide (Publication 5653) describes what examiners look for in a well-documented study; it is internal IRS guidance rather than binding law. Javier does not perform studies or give tax advice.

The Short Answer

Cost segregation reallocates part of a building's depreciable cost to shorter recovery periods, so more depreciation is deducted in the early years of ownership. It does not create new basis, and deductions taken earlier can come back as recapture when the property is sold. Whether it is worthwhile depends on the specific property, the owner's tax position and the holding plan — which is why it is evaluated with a CPA before or soon after purchase rather than assumed.

What Cost Segregation Is

For federal tax purposes, residential rental buildings are generally depreciated over 27.5 years and nonresidential real property over 39 years, while land is not depreciable at all. A building, however, also contains components that may qualify for shorter recovery periods. A cost segregation study identifies and documents those components and their cost, so they can be depreciated on the schedule that applies to them. The recovery periods and conventions are described in IRS Publication 946, How to Depreciate Property.

How Recovery Periods Are Grouped

Shorter-lived personal property — for example, certain appliances, carpeting or furnishings in a furnished rental, often in the 5-year class for residential rental use.
Other personal property — items that fall in the 7-year class.
Land improvements — such as certain paving, landscaping, fencing and site lighting, generally in the 15-year class.
The building itself — structural components, recovered over 27.5 years for residential rental property or 39 years for nonresidential property.

Classification follows the facts of each component and the published asset classes, not a percentage assumed in advance. In a condominium unit, the owner's basis and what can be identified within the unit differ from a whole building, which is part of why results vary so widely.

What Determines Whether It Helps

The property's depreciable basis and how purchase price is allocated between land and building.
What the property actually contains — a furnished unit and a bare shell produce different studies.
The year placed in service and the depreciation rules, including any bonus depreciation, in force for that year — these change through legislation and must be confirmed each time.
Whether the owner can use the deductions, including passive-activity limits on rental losses.
The expected holding period and exit plan, because recapture at sale can offset much of the timing benefit.
The cost of the study compared with the value of the earlier deductions.

Who Performs a Study

Studies are prepared by qualified providers — commonly firms that combine engineering or construction-cost analysis with tax knowledge — and applied on the return by the owner's CPA. The IRS Cost Segregation Audit Techniques Guide (Publication 5653) explains the methodology and documentation examiners expect; it is internal guidance, not binding law, but it is a useful benchmark when comparing providers. Ask how the provider documents component costs, how it handles a condominium unit versus a whole building, and how it coordinates with your CPA, including any Form 3115 filing if the study follows the year of purchase.

Depreciation Recapture at Sale

Depreciation taken reduces basis, so it increases the gain when the property is sold. Gain attributable to depreciation on personal property can be recaptured as ordinary income, and gain attributable to depreciation on real property is subject to its own rules. The treatment is set out in IRS Publication 544, Sales and Other Dispositions of Assets. An investor considering a short hold should model recapture before commissioning a study.

Cost Segregation and the 1031 Exchange

Cost segregation and a Section 1031 exchange require coordinated tax planning. Some depreciation recapture is taxed as ordinary income; a 25% rate is not a universal cap. Section 1031 deferral applies to qualifying real property, and some recapture may remain taxable. Have your CPA and qualified intermediary review the asset classifications and exchange structure before proceeding.

A Note for Foreign Owners

A sale of U.S. real property by a foreign person can be subject to FIRPTA withholding, and the rate and any exception or reduced-withholding certificate depend on the facts — see the IRS FIRPTA withholding page. Withholding is not the final tax; accelerated depreciation affects the gain and recapture reported later. Javier's guides to taxes for foreign buyers in Florida and FIRPTA for foreign sellers cover the surrounding obligations.

Where It Fits in an Investment Decision

Tax planning is one input into an investment, not a substitute for buying the right property. Javier's part is the real estate analysis: the building, its documents and costs, the rental rules that govern it and the purchase terms — the same framework set out in the guide to calculating Miami rental yields. He works alongside the investor's CPA and other advisers, and does not provide tax or engineering services.

Next Steps

If you are evaluating a Miami investment property, start with the property itself through Javier's Miami buying advisory, and bring your CPA in before closing so depreciation, recapture and any exchange planning are part of the decision. You can also contact Javier to discuss a specific purchase.
