You Did a Cost Seg Study. Now You Want to Sell.

This is the most common question we get from owners who used cost segregation: “If I sell, do I lose the tax benefit?”

Short answer: no. You keep the time value of money. But you do owe depreciation recapture tax when you sell.

Here’s exactly how it works, with real numbers on a $750K short-term rental.

The Setup: $750K STR Property

Let’s walk through a real scenario:

Item	Amount
Purchase Price	$750,000
Land Value (20%)	$150,000
Depreciable Basis	$600,000
Cost Seg Study Fee	$795
Accelerated Components (30%)	$180,000
Bonus Depreciation Rate (2025)	100%
Year-1 Accelerated Deduction	$180,000

Without cost segregation, you’d depreciate the entire $600,000 over 27.5 years — about $21,818 per year. With cost seg, you front-load $180,000 into year one.

What Is Depreciation Recapture?

When you sell a property, the IRS requires you to “recapture” the depreciation you’ve taken. There are two types:

• Section 1250 recapture (25% rate) — applies to the portion of depreciation taken on real property (27.5-year components). This is taxed at a maximum of 25%, regardless of your income bracket.
• Section 1245 recapture (ordinary income rate) — applies to personal property (5-year, 7-year components). This is recaptured at your ordinary income tax rate.

The key insight: you would have taken this depreciation eventually anyway. Cost segregation accelerates the timing — it doesn’t create phantom deductions. You’re recapturing real depreciation that you would have claimed over 27.5 years regardless.

If you want a full breakdown of the strategies that reduce recapture exposure — 1031 exchange, stepped-up basis strategy, installment sale, passive loss offset, and continued holding — see our guide to reducing or deferring depreciation recapture. This post focuses on the recapture math itself; that one focuses on the five strategies that change the math.

Year-by-Year ROI: $750K STR

This is the table that matters. It shows the cumulative tax benefit of cost segregation vs. straight-line depreciation, the recapture cost if you sell in that year, and your net benefit after recapture.

Assumes: 37% marginal tax rate, material participation (STR loophole), 25% recapture rate on 1250 property, 37% recapture on 1245 property.

If You Sell After	Cumulative Tax Saved	Recapture Tax Owed	Net Benefit	ROI on $795
Year 1	$58,500	$52,600	$5,900	7.4x
Year 2	$58,500	$47,800	$10,700	13.5x
Year 3	$58,500	$42,900	$15,600	19.6x
Year 5	$58,500	$33,200	$25,300	31.8x
Year 7	$58,500	$23,500	$35,000	44.0x
Year 10	$58,500	$9,100	$49,400	62.1x
Year 15	$58,500	$0	$58,500	73.6x

Cumulative tax saved is constant because the full $180,000 accelerated deduction is taken in year 1 via 100% bonus depreciation. Recapture cost decreases each year as straight-line depreciation catches up — by year 15, there’s nothing extra to recapture. Figures are approximate and depend on individual tax circumstances.

How to Read This Table

Even if you sell in year 1, you’re still ahead by $5,900 after paying recapture tax. That’s a 7.4x return on an $795 study.

By year 5, the net benefit is $25,300. The recapture tax has dropped significantly because straight-line depreciation has partially “caught up” to what you accelerated.

By year 15, straight-line depreciation would have matched the accelerated amount. There’s zero extra recapture — you keep the entire $58,500 tax benefit permanently.

Study Fee Matters More Than You Think

The numbers above assume a $795 study fee. But what if you’re paying $5,000+ for a traditional firm? Let’s compare using a $500K Airbnb — a smaller property where the study fee becomes a bigger percentage of the benefit.

$500K STR: Traditional Firm ($5,000) vs. Cost Seg Smart ($795)

Item	Traditional Firm	Cost Seg Smart
Purchase Price	$500,000	$500,000
Depreciable Basis	$400,000	$400,000
Accelerated (30%)	$120,000	$120,000
Year-1 Tax Savings (37%)	$39,000	$39,000
Study Fee	$5,000	$795

Same property. Same deduction. Same tax savings. The only difference is what you paid for the study. (For typical reclassification amounts by property type, see our benchmarks.)

Now here’s what happens when you sell:

| Sell After | Net Benefit
(after recapture) | $5,000 Firm
(after fee) | $795 Study
(after fee) |

Year 1	$3,900	-$1,100	+$3,105
Year 2	$7,100	+$2,100	+$6,305
Year 3	$10,400	+$5,400	+$9,605
Year 5	$16,900	+$11,900	+$16,105
Year 10	$32,900	+$27,900	+$32,105

Net benefit = year-1 tax savings minus recapture tax owed at sale. “After fee” subtracts the study cost. Both assume identical accelerated allocation — the only variable is what you paid for the study.

If you pay $5,000 for a cost seg study on a $500K property and sell in year 1, you lose money. The recapture tax eats most of the benefit, and the study fee pushes you negative. At $795, you’re positive from day one.

This isn’t a knock on traditional firms — they provide a valuable service, especially for complex commercial properties. But for a residential STR under $1M, the math doesn’t support a $5,000 fee if there’s any chance you sell within 2 years.

Our reports use the same engineering-based methodology (RSMeans cost data, IRS ATG-aligned classification, component-level cost traceability). The deductions are the same. The audit defense package is included. The only difference is the price.

Why Cost Seg Is Still Worth It (Even With Recapture)

1. Time Value of Money

$58,500 in tax savings today is worth far more than $58,500 spread over 27.5 years. At a 5% discount rate, the present value of spreading that same deduction over the full recovery period is roughly $35,000. Cost segregation gives you the full $58,500 now.

2. Recapture Rate Is Lower Than Your Income Rate

You deducted the 5-year personal property at your ordinary income rate (37%). When you sell, Section 1250 recapture on the 27.5-year components is capped at 25%. That rate differential is pure arbitrage — you save at 37% and pay back at 25%.

3. You Can Defer Recapture Entirely

A 1031 exchange defers all depreciation recapture. If you exchange into another investment property, you pay zero recapture tax. The accelerated depreciation rolls into the replacement property — you keep the full tax benefit and reset the clock.

If you’re planning to 1031 exchange, cost segregation is a no-brainer. You get the full accelerated deduction, pay zero recapture, and can do another cost seg study on the replacement property.

4. Reinvestment Returns

The $58,500 you saved in year 1 can be reinvested. If you put it into a rental property generating 8% cash-on-cash return, that’s $4,680 per year in additional income. Over 5 years, that’s $23,400 in extra returns — on top of the tax savings themselves.

What About the IRS?

Cost segregation is not a “loophole” or aggressive tax position. It’s explicitly supported by IRC Section 168, the IRS’s own Cost Segregation Audit Technique Guide (Publication 5653), and decades of case law including Hospital Corporation of America v. Commissioner.

Every Cost Seg Smart report includes an audit defense package aligned with IRS ATG guidelines. If you’re audited, you have structured documentation designed for direct use by your CPA.

The Bottom Line

Scenario	Net Benefit After Recapture
Sell in 1 year	$5,900 (7.4x ROI)
Sell in 3 years	$15,600 (19.6x ROI)
Sell in 5 years	$25,300 (31.8x ROI)
Hold 15+ years	$58,500 (73.6x ROI)
1031 Exchange (any year)	$58,500 (zero recapture)

Cost segregation is worth it at every holding period. Even the worst-case scenario (selling in year 1) still produces a positive return. The longer you hold, the better it gets. And if you 1031 exchange, you keep everything.

Recapture Math: A Concrete Example

Here is the exact math on a $750K short-term rental sold after 5 years to show how recapture actually works line by line.

how the classification process works →

At purchase: You buy for $750K. Land is 20% ($150K), leaving a depreciable basis of $600K. Your cost segregation study reclassifies $180K (30%) to 5-year and 15-year property. With 100% bonus depreciation, you deduct the full $180K in Year 1. At the 37% federal bracket, that saves you $66,600 in Year 1 taxes.

At sale (Year 5): Under straight-line depreciation, you would have deducted approximately $109K over 5 years on the full $600K basis (27.5-year schedule). Your cost seg study accelerated $180K in Year 1. The “excess” depreciation subject to recapture is the difference: $180K minus what straight-line would have recovered on those same components over 5 years.

Section 1245 recapture (5-year personal property like appliances, flooring, cabinetry): This portion is fully depreciated after 5 years under both methods, so there is zero excess recapture. You keep the full time-value-of-money benefit of having those deductions in Year 1 instead of spread over 5 years.

Section 1250 recapture (15-year land improvements like pools, landscaping, driveways): After 5 years, straight-line would have recovered about 33% of these assets. The remaining 67% that was accelerated into Year 1 via bonus depreciation is recaptured at a maximum rate of 25%. On $60K of 15-year property, that is roughly $40K in excess depreciation taxed at 25% = $10,000 in recapture tax.

Net result after 5 years: You saved $66,600 in Year 1. You owe approximately $10,000 in recapture at sale. Net benefit: $56,600, plus 5 years of reinvestment returns on the $66,600 you kept in your pocket. That is a 71x return on an $795 study.

Frequently Asked Questions How is depreciation recapture calculated when selling after cost segregation?

When you sell, the IRS recaptures depreciation in two categories. Section 1250 recapture on real property (building structure and land improvements) is taxed at a maximum of 25%. Section 1245 recapture on personal property (appliances, fixtures, flooring) is taxed at ordinary income rates, but only to the extent of actual gain on those specific assets. Your adjusted basis at sale equals your original purchase price minus all depreciation taken. The total gain (sale price minus adjusted basis) is split between recapture and capital gain portions. Cost segregation increases your total depreciation taken, which lowers your adjusted basis and increases the recapture amount — but the time value of having that money years earlier typically produces a net benefit of 5-10x the additional recapture. Can I avoid recapture entirely when selling after cost segregation?

Yes, through a 1031 like-kind exchange (IRC Section 1031). By reinvesting the sale proceeds into a replacement investment property within the exchange timeline (45 days to identify, 180 days to close), all capital gains and depreciation recapture are deferred. You can chain 1031 exchanges indefinitely. Alternatively, holding the property until death triggers a stepped-up basis under IRC Section 1014, which eliminates all accumulated depreciation recapture for your heirs. Many investors combine both strategies across their career. Is cost segregation still worth it if I plan to sell the property?

Yes, for holding periods of 2+ years. On a $750K property, cost segregation generates approximately $64,000 in additional Year 1 tax savings. Over a 7-year hold at 8% returns, that grows to roughly $110,000. The additional recapture at sale is typically $10,000-$24,000, leaving a net benefit of approximately $86,000. Even conservative assumptions produce strong positive returns. The breakeven holding period is typically under 2 years. Cost Seg Smart studies start at $495. What is the tax rate arbitrage benefit of cost segregation?

You deduct depreciation at your ordinary income tax rate (up to 37% federal). When you sell, recapture is taxed at a maximum of 25% (Section 1250) for real property. This 12-percentage-point spread is a permanent tax savings, not a deferral. For every $10,000 in depreciation deductions, you save $3,700 in taxes at the 37% bracket but would owe only $2,500 in recapture at 25%. The $1,200 difference per $10,000 is pure savings that compounds over the holding period.
