Is Cost Segregation Worth It for Your Property?

Is Cost Segregation Worth It? Four Questions to Ask First

Before you get a proposal from anyone, work through these four questions honestly. They cover the factors that actually determine whether a study will pay for itself, in roughly the order they matter.

1. How large is your depreciable basis? This is your purchase price minus land value, plus any capital improvements. Cost segregation studies find more to reclassify, and generate more savings, on properties with a larger basis. A study on a basis in the low hundreds of thousands is a very different proposition than one on a multimillion-dollar building.
2. What's your marginal tax bracket? The dollar value of an accelerated deduction scales directly with the rate it's taxed against. An owner in a higher bracket gets more real, spendable benefit from the same deduction than an owner in a lower one.
3. How long do you plan to hold the property? Because of depreciation recapture, a study performed shortly before a planned sale can produce a worse after-tax outcome than not studying at all. A multi-year hold gives the front-loaded deduction time to actually work in your favor before recapture becomes a consideration.
4. Can you actually use the resulting losses? If you're a passive investor without much other passive income, generated losses may sit unused for a while due to passive activity limitations rather than reducing your tax bill this year. A real estate professional or an owner with substantial active income to offset generally sees the benefit land faster.

Estimate Your Own Numbers

The calculator below is a simplified illustration, not a substitute for an engineering-based study. Here's what each input means:

• Purchase price, excluding land value. Only the building and its components depreciate. Land never does, so leaving land value in will overstate your result.
• Property type. Residential and short-term rental property generally depreciate over 27.5 years under standard rules; commercial property depreciates over 39 years. This changes both the standard deduction and the useful life used in the estimate.
• Estimated land value percentage. A rough share of your purchase price attributable to land alone, commonly somewhere between 10% and 30% depending on location, though your actual figure should come from an appraisal or assessor data.
• Estimated share reclassified. The portion of your depreciable basis a study might reclassify into 5, 7, or 15-year property. This varies significantly by property type and finish level; the default figures are broad, conservative starting points, not a promise.
• Your marginal tax rate. Used only to translate the additional first-year deduction into an estimated tax savings figure.

Treat these numbers as a starting point for a conversation, not a final answer. Every real study begins with a feasibility review that looks at your actual property, not a generic percentage.
