Depreciation Recapture on a Mixed-Use Property

Two depreciation lives, two recapture pools

A mixed-use building — say, ground-floor retail with upper-floor apartments — carries two depreciation schedules: the residential portion over 27.5 years and the commercial portion over 39 years. When you sell, the recapture calculation must be performed separately for each portion. The recapture rate is the same for both (up to 25% for Section 1250 real property), but the accumulated depreciation pool will differ because the commercial portion depreciates more slowly.

Example: a $1,200,000 building allocated 60% residential ($720,000) and 40% commercial ($480,000). After 10 years: residential depreciation = $720,000 ÷ 27.5 × 10 = $261,818; commercial depreciation = $480,000 ÷ 39 × 10 = $123,077. Total recapture exposure = $384,895 — all taxed at up to 25% regardless of which portion it came from.

Cost segregation makes allocation more complex

If you completed a cost segregation study on the mixed-use building, you also have 5-year and 15-year components allocated between the residential and commercial portions. The 5-year and 7-year personal property components create Section 1245 recapture — taxed at ordinary income rates, not the 25% cap. You need the cost seg engineer's report to separate which accelerated components are residential-portion and which are commercial-portion, because the allocation affects both your depreciation schedule and the character of recapture at sale.

Keep the cost seg report and the allocation workpapers permanently with your tax records.

Reporting at sale

At sale, report the total gain on Schedule D (for long-term capital gains) and any Section 1250 unrecaptured gain separately (the 25% rate applies on the collectibles worksheet in the tax instructions, effectively). Use Form 4797 to report depreciation recapture from the sale. Your tax professional will need: (1) the original allocated basis for each portion, (2) the annual depreciation claimed on each portion, and (3) the sale price allocation between residential and commercial.

Two kinds of recapture, not one

It is a mistake to think 'recapture' is a single 25% number. A mixed-use building actually carries two flavors of recapture, and both must be split between the residential and commercial portions. First, the straight-line depreciation on the building shell and land improvements is unrecaptured Section 1250 gain, taxed at a maximum federal rate of 25%. Second, if you ran a cost segregation study, the 5- and 7-year personal-property components are Section 1245 property, and their depreciation is recaptured as ordinary income at your regular rate — with no 25% cap.

Because the residential and commercial portions may hold different mixes of 1245 and 1250 property, the character of your gain (ordinary vs. 25% vs. 0/15/20% capital) can only be computed correctly if the component schedule ties each asset to a use and a Code section. Blending them risks over-reporting the 1245 ordinary income or under-reporting it — either of which an examiner can unwind.

Allocating the sale price — the trap

At sale you must split the proceeds between the residential and commercial portions, and the split drives how much gain and recapture lands in each pool. Use the same methodology you used to allocate the purchase price — typically square footage, relative fair market value, or a formal appraisal — and document it. Buyers and sellers sometimes have opposite incentives on the allocation, so a contemporaneous appraisal is the strongest support. Remember too that only the building portions are depreciable; the land allocation is not, and it produces plain capital gain with no recapture. Getting the land/building and residential/commercial splits right at both ends of ownership is what keeps the recapture computation defensible.

A worked example with the tax dollars

Take the building above: $1,200,000 depreciable basis, 60% residential / 40% commercial, sold after 10 years with $384,895 of total depreciation claimed ($261,818 residential + $123,077 commercial), all straight-line. Assume land was a separate $300,000 (non-depreciable) and you sell the whole property for $1,900,000, allocating $400,000 to land and $1,500,000 to the building. Adjusted basis in the building is $1,200,000 − $384,895 = $815,105; total adjusted basis with land is $1,115,105.

Total gain = $1,900,000 − $1,115,105 = $784,895. Of that, $384,895 is unrecaptured Section 1250 gain taxed at up to 25% (about $96,000), and the remaining $400,000 is long-term capital gain at 0/15/20% (roughly $80,000 at the 20% rate). A high-income seller may also owe the 3.8% Net Investment Income Tax on the gain — about $29,800 more. The residential and commercial split does not change these totals here because both portions are straight-line 1250 property, but it would matter if cost-segregated 1245 components were present, because their recapture would be carved out as ordinary income first.

Owner-occupied mixed use and Section 121

A common variant is a building you live in while renting the rest — an owner-occupied duplex, or an apartment over your storefront. The Section 121 exclusion can shelter the gain on the portion you used as your principal residence (up to $250,000 single / $500,000 married), but it never covers depreciation recapture. So even if the residence portion qualifies for full exclusion, the depreciation you claimed on the rental/business portion is still unrecaptured Section 1250 gain (and any 1245 recapture is still ordinary). Post-2008 'non-qualified use' rules further limit how much of the gain on a unit that was both rented and lived in can be excluded. Treat the residence and the income portions as separate sales in your analysis.

Reporting mechanics and recordkeeping

Report the depreciation recapture and the sale of the business/rental portions on Form 4797: Section 1245 recapture in Part III as ordinary income, and the Section 1250 real property gain flowing to Part I as long-term gain that carries to Schedule D. The 25% rate on the unrecaptured Section 1250 gain is applied through the Unrecaptured Section 1250 Gain Worksheet in the Schedule D instructions, not by a separate form. Keep, permanently: the purchase-price allocation, the cost segregation report and workpapers, the year-by-year depreciation schedules for each portion, and the sale-price allocation. On a mixed-use property these records are what let you prove which dollars are ordinary, which are 25% gain, and which are ordinary capital gain — and they are exactly what an auditor asks for.

Partial dispositions and later improvements

Recapture tracking gets busier over a long hold because the building rarely stays static. When you replace a major component — a roof, an HVAC system, a parking lot — you can elect a partial disposition under the tangible property regulations, writing off the remaining basis of the retired component and stopping its depreciation. That disposition has its own small recapture computation, and on a mixed-use building it must be allocated to the residential and/or commercial portion the component served. Handled well, a partial disposition also avoids future recapture on the old component, since you removed it from service rather than leaving it on the books.

Similarly, improvements you add later start their own depreciation schedules on their own placed-in-service dates, and each must be tagged to a use (and, for cost-segregated pieces, to a Code section). By the time you sell, a decade-old mixed-use building may have a dozen asset 'vintages' across two uses. The only way to report recapture correctly is a clean fixed-asset ledger that carries the use, class, and accumulated depreciation of every item — which is why the recordkeeping discipline above pays off precisely at sale.

The state tax angle

Do not forget state income tax on the recapture. Most states that levy an income tax treat the entire gain — including both the unrecaptured Section 1250 gain and the Section 1245 ordinary recapture — as ordinary income taxed at the state's regular rates. States generally do not mirror the federal 25% cap on unrecaptured Section 1250 gain or the preferential 0/15/20% long-term capital gains brackets, so your combined tax on the recapture can be materially higher than the federal number alone suggests. A handful of states also require depreciation add-backs where their allowed depreciation differed from the federal amount (for example, states that decoupled from bonus depreciation), which can change the state basis and therefore the state gain.

For a mixed-use building this means running the recapture computation twice — once for federal and once for your state (and any state where the property sits, if different from your residence) — and budgeting for both. High-tax states can turn an already-large recapture bill into a decisive factor in whether to sell outright or defer through a 1031 exchange.

Frequently asked questions

Do I need to track residential and commercial depreciation separately on a mixed-use building?

Yes. Each portion has a different recovery period (27.5 vs. 39 years), and at sale you must compute recapture on each pool independently. Commingling the depreciation creates errors in the gain calculation.

Is the recapture rate different for residential vs. commercial portions?

No. Both are Section 1250 property, so recapture on both is taxed at up to 25%. The difference is only in the annual depreciation amount — the commercial portion depreciates more slowly.

How do I allocate the sale price between residential and commercial portions?

Use the same method you used to allocate the original purchase price — typically square footage. A formal appraisal allocating the sale price is ideal for a large property.

Are there two different recapture tax rates on a mixed-use sale?

Yes. Straight-line depreciation on the building shell and land improvements is unrecaptured Section 1250 gain taxed at up to 25%. Cost-segregated 5- and 7-year personal-property components are Section 1245 property recaptured as ordinary income at your regular rate, with no 25% cap. Both must be split between the residential and commercial portions.

If I live in one unit of a mixed-use building, can Section 121 shelter the recapture?

No. Section 121 can exclude gain on the portion you used as your principal residence, but it never shelters depreciation recapture. The depreciation claimed on the rental or business portion is still unrecaptured Section 1250 gain (or Section 1245 ordinary recapture), even if the residence portion's appreciation is fully excluded.

What forms report recapture on a mixed-use sale?

Form 4797 — Section 1245 recapture in Part III as ordinary income, and Section 1250 real property gain in Part I flowing to Schedule D. The 25% rate on unrecaptured Section 1250 gain is computed on the Unrecaptured Section 1250 Gain Worksheet in the Schedule D instructions.
