1031 Exchange Depreciation Recapture: Defer, Eliminate, or Pay
Every year you hold an investment property, the IRS lowers your tax basis through depreciation. When you sell, that accumulated deduction comes back as taxable income — at a rate of up to 25% federal — before any capital gains rate applies. A 1031 exchange defers this entirely, but the liability does not disappear. Understanding where it goes is as important as understanding how to defer it.
How depreciation works in investment real estate
The IRS allows owners of income-producing real estate to deduct a portion of the property's cost each year, reflecting the theoretical wear and tear on the structure. The deduction is calculated on the building value only — land is not depreciable — spread over a fixed schedule:
- Residential rental property: 27.5 years, straight-line (MACRS)1
- Commercial and industrial property: 39 years, straight-line
- Land: not depreciable
A $900,000 purchase with $150,000 in land value leaves $750,000 of depreciable building. A residential owner deducts approximately $27,273 per year ($750,000 ÷ 27.5). After 12 years: $327,273 in cumulative depreciation deductions. That amount lowers the adjusted basis dollar for dollar — which matters enormously when you sell.
The recapture problem: what happens when you sell
When you sell, your realized gain is calculated against the adjusted basis — after all those depreciation deductions. The portion of gain attributable to accumulated depreciation is "recaptured" and taxed under a separate set of rules, at a higher rate than ordinary long-term capital gains:
| Gain layer | 2026 federal rate | + NIIT | Combined max |
|---|---|---|---|
| §1250 unrecaptured depreciation (buildings) | 25%2 | 3.8% | 28.8% |
| Long-term capital gain above recapture | 20%3 | 3.8% | 23.8% |
| §1245 recapture (equipment, cost-seg components) | up to 37% | 3.8% | up to 40.8% |
The NIIT of 3.8% applies to net investment income when your modified AGI exceeds $200,000 (single) or $250,000 (married filing jointly).4 These thresholds are not indexed for inflation. Most investors completing seven-figure exchanges are in all three layers simultaneously.
The tax order matters: recapture is always recognized first. If your accumulated depreciation is $380,000 and your boot or recognized gain is $200,000, the entire $200,000 is classified as §1250 recapture — taxed at 25% plus NIIT — not at the lower 20% capital gains rate.
Worked example: 17-year residential rental
An investor purchased a fourplex in 2009 for $750,000. At purchase, the land was appraised at $100,000 and the building at $650,000. No cost segregation was done. The property is now under contract to sell for $1,600,000, with $110,000 in selling costs.
| Tax basis calculation | |
|---|---|
| Original purchase price | $750,000 |
| Annual depreciation ($650,000 ÷ 27.5 years) | $23,636/yr |
| Depreciation taken over 17 years | ($401,818) |
| Adjusted basis at time of sale | $348,182 |
| Gain and tax if sold taxable (no exchange) | |
|---|---|
| Sale price | $1,600,000 |
| Less selling costs | ($110,000) |
| Net sale value | $1,490,000 |
| Adjusted basis | ($348,182) |
| Total realized gain | $1,141,818 |
| §1250 recapture at 25%: $401,818 × 25% | $100,455 |
| LTCG at 20%: ($1,141,818 − $401,818) × 20% | $148,000 |
| NIIT at 3.8%: $1,141,818 × 3.8% | $43,389 |
| Total federal tax | ~$291,844 |
| Plus state tax (varies; 0–13.3%) | additional |
What actually happens to deferred recapture in a 1031 exchange
A 1031 exchange does not erase the tax. It moves the tax liability forward by attaching it to the replacement property through a carryover basis. The replacement property's adjusted tax basis is set at the old basis — $348,182 in the example above — regardless of what you paid for the new property. The deferred gain (including all $401,818 of accumulated depreciation) remains embedded in the replacement property until you trigger it.
This creates a compounding dynamic: the replacement property begins depreciating from its allocated basis in the new property for tax purposes, not the full purchase price. The difference between what you paid and your carryover basis is what accountants call "excess basis" — it does not generate additional depreciation deductions, and it stays locked in as potential future gain.
Three ways the deferred liability eventually resolves
- Another exchange. You can chain 1031 exchanges indefinitely. Each exchange rolls the deferred gain and carryover basis forward into the next property. Investors who stay in real estate long-term can defer recapture and capital gains for decades. There is no IRS limit on the number of exchanges.
- Taxable sale. When the chain finally ends — you take cash, move into a non-qualifying property, or no longer want to exchange — the full accumulated deferred gain is recognized and taxed in that year. Careful exit planning with a CPA and financial advisor helps sequence the recognition across multiple years or coordinate with retirement income strategies.
- Step-up in basis at death. Heirs who inherit an investment property receive a stepped-up cost basis equal to the property's fair market value at the date of death under IRC §1014.5 This permanently eliminates all accumulated deferred gain — including the §1250 recapture that a 1031 investor has been carrying for decades. A $1.1 million deferred tax liability built over 30 years of exchanges and depreciation goes to zero when the property passes to heirs. This is the most powerful exit strategy available to an investor who does not need liquidity during their lifetime.
Cost segregation and bonus depreciation (2026)
Some investors accelerate depreciation through cost segregation studies, which reclassify portions of a building's components — wiring, flooring, fixtures, land improvements — into shorter-lived property categories (5, 7, or 15 years) that qualify for bonus depreciation. The One Big Beautiful Bill Act (OBBBA, July 2025) restored 100% bonus depreciation permanently for qualifying property placed in service after January 19, 2025.6
This matters for recapture planning in two ways:
- Accelerated depreciation creates §1245 recapture on the personal-property components — taxed at ordinary income rates (up to 37%), not the 25% §1250 rate. A property with significant cost-seg components can have a higher blended recapture rate than a property depreciated on straight-line schedule only.
- A 1031 exchange defers §1245 recapture too, but the basis allocation to each property class carries forward, so a future taxable sale still triggers the higher ordinary-income rate on those components.
Investors who have done cost segregation on current properties and are considering an exchange need a financial advisor who can model both the §1250 and §1245 layers in the exit-tax estimate.
What a financial advisor models before you move the money
The qualified intermediary keeps your exchange compliant. Your CPA estimates the tax in each scenario. A fee-only financial advisor does the planning work that sits between those two roles:
- Exchange vs. taxable sale comparison. Model the after-tax net proceeds in each scenario against the household balance sheet — not just "defer the tax" but "defer and earn X on the deferred capital vs. diversify and accept the tax today."
- Carryover basis forecasting. Project forward: if you exchange today, what is the embedded gain in year 5, 10, and at death? What does the annual depreciation deduction look like on the carryover basis vs. the purchase price?
- Estate and step-up planning. If you are holding real estate into your 70s or 80s, the step-up-at-death strategy deserves explicit modeling. The value of deferral increases dramatically if the basis reset is a likely exit.
- Replacement property stress test. An exchange that locks you into a high-leverage property to avoid debt-relief boot may create more risk than the tax it saves. A financial advisor can put numbers on that tradeoff.
Run the 1031 exchange calculator to estimate your total deferred tax, then read the boot guide to understand which missteps would trigger partial recognition even in an otherwise clean exchange.
