1031 Exchange Depreciation Recapture Explained

What depreciation recapture is

When you own a rental or investment property, the IRS lets you deduct a portion of the building's cost each year as depreciation. For residential rental property, you spread the cost over 27.5 years. For commercial property, 39 years. These deductions reduce your taxable rental income every year you own the property.

When you sell, the IRS wants those deductions back. Depreciation recapture is the tax on the total depreciation you deducted during ownership. Unrecaptured Section 1250 gain is taxed at a maximum federal rate of 25% - meaning if your ordinary income tax rate is lower than 25%, you pay the lower rate on the recapture portion. For most investors selling properties with significant gains, the effective recapture rate is 25%.

Think of it this way: the IRS gave you a tax break on the depreciation deductions during ownership. Now they're reclaiming that benefit at sale. It's a separate tax layer that sits on top of your regular capital gains tax.

Why it matters more than you think

Most investors focus on capital gains when they think about their tax bill. But depreciation recapture is often the largest single tax component for long-held properties.

Consider a residential rental purchased for $500,000 (with $400,000 in depreciable improvements) and held for 20 years:

• Annual depreciation: $400,000 / 27.5 = $14,545
• Total depreciation over 20 years: $290,909
• Recapture tax at maximum 25% rate: up to $72,727

That's up to $72,727 before you even get to capital gains, NIIT, or state taxes. For a property that appreciated from $500,000 to $900,000, the depreciation recapture tax alone represents more than 18% of the total gain.

This is why investors who calculate only their "capital gains tax" are consistently surprised by their actual tax bill. The calculator breaks out recapture separately so you can see exactly how much of your liability comes from each source.

How to calculate it

Estimated recapture tax = Total depreciation taken × your applicable rate (maximum 25%)

The total depreciation includes:

• Regular annual depreciation on the original building
• Depreciation on capital improvements (each improvement starts its own depreciation schedule)
• Any bonus depreciation or accelerated depreciation you claimed on qualifying components (appliances, carpeting, certain land improvements)

For bonus depreciation and accelerated cost segregation items, the rules are more nuanced. Consult your CPA if you've done a cost segregation study.

Example calculation:

Note: This is a simplified illustration. In practice, the original building ($480,000) and the roof improvement ($25,000) each have their own depreciation schedules starting from their respective placed-in-service dates. The roof added in Year 5 would have 9 years of depreciation, not 14. Your CPA will calculate the precise total.

The "allowed or allowable" trap

This catches investors who never claimed depreciation. Under IRC Section 1016(a)(2), the IRS reduces your basis by the depreciation "allowed or allowable" - whichever is greater.

Translation: if you owned a rental property for 15 years and never took a single depreciation deduction on your tax returns, the IRS still treats your basis as if you had. You get the worst of both worlds: no tax benefit during ownership, but full recapture tax at sale.

If you've been skipping depreciation deductions, file amended returns for the open years and file Form 3115 (Change in Accounting Method) to catch up on all prior unclaimed depreciation. Your CPA can do this. You'll get the deductions you missed and be in the same position as if you'd been claiming them all along - which is where the IRS will put you at sale regardless.

How a 1031 exchange defers recapture

A properly executed 1031 exchange defers all depreciation recapture tax along with capital gains, NIIT, and state taxes. The full gain - including the recapture portion - rolls into the replacement property.

No recapture tax is due at the time of the exchange. But the deferred depreciation doesn't disappear. It transfers to the replacement property through the carryover basis.

What happens to depreciation on the replacement property

This is where it gets nuanced. When you acquire replacement property through a 1031 exchange, you get a blended basis for depreciation purposes.

Your replacement property's depreciable basis consists of two components:

1. Carryover basis: The remaining depreciable basis from your relinquished property. This continues to depreciate on the original schedule (27.5 or 39 years from the original placed-in-service date).

2. Excess basis: If your replacement property costs more than your relinquished property's adjusted basis, the excess starts a new depreciation schedule from the acquisition date.

Example: You sell a property with a remaining depreciable basis of $180,000 and 10 years left on its depreciation schedule. You buy a replacement for $700,000 with $560,000 allocated to improvements.

• Carryover basis: $180,000 continues depreciating over the remaining 10 years
• Excess basis: $380,000 ($560,000 - $180,000) starts a new 27.5-year schedule

This dual-schedule tracking is one reason serial exchangers need a CPA who understands 1031 exchanges. The basis calculations compound with each exchange.

Recapture in serial exchanges

Investors who exchange multiple times accumulate deferred depreciation recapture across the chain. Each exchange carries the prior recapture obligation forward.

If you've done three exchanges over 30 years, the recapture amount at final disposition includes the accumulated depreciation from all properties in the chain. This can be a very large number.

The silver lining: if the final property in the chain passes to your heirs, the stepped-up basis at death eliminates the deferred recapture along with the deferred capital gains. This is the foundation of the "swap 'til you drop" strategy.
