Is a Cost Segregation Study Worth It? A Realistic Assessment
I get this question more than any other. Property owners hear about cost segregation, see the large Year 1 savings numbers, and wonder if it is too good to be true. The honest answer: for most rental property owners, it is one of the best tax moves available. But it is not right for everyone, and the industry does a poor job of explaining when it does not make sense.
Whether cost segregation is worth it for you depends on three things: your property value, your marginal tax rate, and how long you plan to hold the property.
When It IS Worth It
Let me show the math first. These estimates assume a residential rental property with 100% bonus depreciation (restored permanently as of 2025) and a 37% federal marginal tax rate. The "reclassified" column shows the portion of the building's depreciable basis that gets moved from 27.5-year to 5, 7, or 15-year classes.
| Property Value | Est. Reclassified | Year 1 Tax Savings | Typical Study Cost | Net Benefit |
|---|---|---|---|---|
| $300,000 | ~$60,000 - $84,000 | ~$22,000 - $31,000 | $795 - $3,000 | $19,000 - $30,000 |
| $500,000 | ~$100,000 - $140,000 | ~$37,000 - $52,000 | $795 - $3,000 | $34,000 - $51,000 |
| $750,000 | ~$150,000 - $210,000 | ~$55,500 - $77,700 | $995 - $5,000 | $50,500 - $76,700 |
| $1,000,000+ | ~$200,000 - $280,000 | ~$74,000 - $103,600 | $1,295 - $7,000 | $67,000 - $102,300 |
Even at the low end of savings and the high end of study cost, a $300,000 property generates nearly $19,000 in net Year 1 tax benefit. That is a clear yes for any property owner in a meaningful tax bracket.
When It Might NOT Be Worth It
In my research, I identified four scenarios where cost segregation may not make financial sense:
Property value under $200,000. The reclassified amount on a very low-value property may not generate enough savings to justify even a budget-priced study. A $150,000 rental might reclassify $30,000 to $40,000, producing $11,000 to $15,000 in savings -- still positive, but the margin gets thin if you are paying $3,000 or more for the study. At the lower price points ($795 or so), it can still work.
Planning to sell within 1-2 years. Depreciation recapture (discussed below) means you pay back a portion of the accelerated deductions when you sell. If you are selling soon, you get the benefit for a very short period before recapture kicks in. The time value of money still favors doing the study in most cases, but the advantage shrinks significantly on a short hold.
Low tax bracket. The savings scale directly with your marginal rate. At 37%, the numbers are compelling. At 22%, they are about 40% smaller. At 12%, the benefit may not justify the cost on lower-value properties.
Personal residence. Cost segregation only applies to investment or business property. Your primary home does not qualify, regardless of its value.
The Recapture Question
This is the objection I hear most often, and it is the most misunderstood part of cost segregation. Yes, when you sell the property, you will owe depreciation recapture tax at 25% on the accelerated depreciation you claimed. Here is why that is almost always still a good deal:
You had use of the money for years. If you took $50,000 in accelerated deductions in Year 1 and sell in Year 7, you had that $50,000 working for you for seven years. Even at a modest 7% return, that $50,000 grew to roughly $80,000. The recapture tax of $12,500 (25% of $50,000) is a fraction of the benefit.
You saved at 37%, you repay at 25%. If your marginal rate when you claimed the deduction was 37%, you saved $18,500 on a $50,000 deduction. You repay $12,500 at the 25% recapture rate. That is a permanent $6,000 rate arbitrage, before any time value consideration.
A 1031 exchange defers recapture entirely. If you exchange into another investment property, recapture is deferred along with all other gains. Many investors never pay recapture because they keep exchanging.
Death eliminates it. Under current law, heirs receive a stepped-up basis that wipes out all accumulated depreciation recapture. This is not a morbid planning strategy -- it is a factual reality of the tax code that benefits long-term holders.
Bonus Depreciation Status: Better Than Ever
The bonus depreciation landscape has shifted dramatically in favor of property owners. Here is the recent history:
| Tax Year | Bonus Depreciation Rate | Source |
|---|---|---|
| 2022 | 100% | TCJA (original) |
| 2023 | 80% | TCJA phase-down |
| 2024 | 60% | TCJA phase-down |
| 2025+ | 100% (permanent) | One Big Beautiful Bill Act |
The One Big Beautiful Bill Act, signed in July 2025, permanently restored 100% bonus depreciation for 2025 and all future years. This means every dollar of reclassified building components is fully deductible in Year 1. There is no longer any uncertainty about phase-downs or sunsets. The math for cost segregation is better now than it has been at any point in the last several years.
The Real Question
After reviewing dozens of studies and talking to CPAs who file hundreds of these, I have come to a simple framework: does the Year 1 tax savings exceed the study cost by at least 5x?
For a $500,000 rental at the 37% bracket, the answer is unambiguously yes. The savings-to-cost ratio is typically 15x to 58x depending on the provider you choose. Even at the 24% bracket, the ratio is 10x to 38x.
For a $200,000 property at the 22% bracket, the answer becomes "probably yes, but shop carefully on price." A $795 study still delivers strong returns. A $5,000 study might not.
The industry makes this more complicated than it needs to be. The math is straightforward, the IRS supports it, and with 100% bonus depreciation now permanent, the timing has never been better.
