Section 1245 vs 1250 when you sell a cost-segregated rental

A 15-year parking lot or landscaping allocation is not automatically Section 1245 or Section 1250 at sale. The IRS cost-segregation guide identifies both property types within the 15-year land-improvement asset class. First determine the legal tax character of each component, then allocate sale proceeds and calculate gain and depreciation for that component. Section 1245 recapture is ordinarily taxed at ordinary rates; Section 1250 real property can also generate ordinary recapture when accelerated or bonus depreciation exceeds straight-line. Only the remaining eligible depreciation-related gain is considered for the maximum 25 percent unrecaptured Section 1250 rate.

If a sale is under contract, AE can reconcile the engineering study, fixed-asset ledger, depreciation claimed, and draft closing allocation before the return is prepared. Bring those records to a sale-year review.

The question: does 15-year mean Section 1245?

No. A recovery period describes when basis may be deducted; Sections 1245 and 1250 describe what kind of asset was disposed of and how prior depreciation affects gain. The IRS Cost Segregation Audit Technique Guide lists parking lots, site work, and similar 15-year land improvements in asset class 00.3 and expressly says that class includes both Section 1245 and Section 1250 property. The study's asset description, physical function, ownership, placed-in-service facts, and supporting authority matter more than a line labeled “15 year.” Fee-simple land is different: it is not depreciable and has no depreciation recapture.

A building and its structural components are generally Section 1250. Equipment, removable personal property, and some specially classified components can be Section 1245. Qualified improvement property is another example of 15-year property that can be Section 1250. Do not classify all short-life assets together or assume every land improvement earns the same sale-year rate. See the IRS disposition rules in Publication 544 and the Form 4797 instructions.

Three layers of sale gain, calculated asset by asset

Allocate an economically supportable portion of the amount realized to each asset sold, subtract its adjusted basis, and limit any recapture to that asset's gain. The resulting gain may pass through several tax-character rules; it is not simply “depreciation at 25 percent plus appreciation at 20 percent.”

The 3.8 percent net investment income tax may apply to a particular seller's investment income; state tax and entity-level rules require separate review. A C corporation can also face the distinct Section 291 rule. None of those amounts should be inferred solely from the cost-segregation report.

Why a 15-year Section 1250 component can still create ordinary income

For Section 1250 property held more than one year, “additional depreciation” generally means depreciation above what straight-line would have allowed. The familiar 27.5- or 39-year building usually uses straight-line and may have no ordinary Section 1250 recapture. A 15-year land improvement classified as Section 1250 can be different if declining-balance or bonus depreciation was claimed. The IRS's Section 1250 additional-depreciation explanation and Form 4797 Part III instructions govern the computation. After any ordinary recapture, the Schedule D unrecaptured-Section-1250 worksheet determines whether some remaining gain falls in the maximum-25-percent group.

Worked example: the same 15-year label, two different sale results

Assume a separately tracked parking-area asset has $100,000 original basis, $60,000 depreciation allowed or allowable, $40,000 adjusted basis, and a supportable $110,000 sale-price allocation. Its $70,000 gain is the upper limit for recapture. The figures below are simplified illustrations, not a classification opinion about this particular parking area or a tax estimate for the whole property.

• If the asset is Section 1245: up to $60,000 of gain is ordinary depreciation recapture; the remaining $10,000 may enter the Section 1231 computation if the holding-period and use requirements are met.
• If the asset is Section 1250: assume a hypothetical $20,000 of straight-line depreciation for the same period. The $40,000 excess depreciation may be ordinary Section 1250 recapture. The remaining $30,000 may enter the Section 1231 computation; within that amount, up to $20,000 may be in the unrecaptured-1250 rate group, subject to the Schedule D worksheet and other limitations, leaving $10,000 outside that special rate group.

If the supportable allocation produced only $10,000 of gain, recapture could not exceed that $10,000 simply because $60,000 had been deducted. Conversely, a cost-segregation study can increase depreciation claimed before an early sale, increasing the possible recapture compared with a no-study schedule. Both the timing of deductions and the exit tax must be modeled.

What to do before signing a sale or exchange agreement

1. Rebuild the asset ledger. Match the original closing allocation, study report, later improvements, partial dispositions, and Form 4562 schedules to every asset still owned. Depreciation allowed or allowable affects adjusted basis even when a deduction was missed.
2. Classify each line, not each recovery period. Ask the study preparer to identify the authority for treating each disputed 15-year parking, paving, fencing, site-utility, or landscaping component as Section 1245 or 1250. Reconcile the report with the 15-year land-improvements guide and IRS asset tables.
3. Support the sale allocation. Separate land, building, personal property, and site improvements using the actual transaction and defensible fair values. A buyer's preferred allocation is not automatically the seller's tax result. Form 8594 applies when the transaction is an applicable asset acquisition of a trade or business, not to every standalone rental sale.
4. Compute each gain and recapture limit. For each asset, calculate amount realized less adjusted basis, then test Section 1245 or 1250 ordinary recapture. Run the Section 1231 netting/lookback and unrecaptured-Section-1250 worksheet only after those computations.
5. Compare exit structures without assuming a free pass. A Section 1031 exchange generally concerns qualifying real property after 2017, but Section 1245 property can sometimes also be real property for Section 1031 purposes; cash, non-like-kind property, and recapture rules still require analysis. The Form 8824 instructions show an apartment example in which Section 1245 real property produces current ordinary recapture despite an exchange for Section 1250 replacement property.

Installments, passive losses, and replacement plans

Seller financing does not necessarily spread the tax on recapture: IRS Publication 537 requires ordinary Section 1245 and Section 1250 recapture in the year of sale. Remaining eligible gain can enter the installment calculation, and unrecaptured Section 1250 gain may affect later payments. Test whether the first-year cash can pay the first-year tax before agreeing to a note.

Suspended passive losses may be released on a fully taxable disposition of the entire activity to an unrelated party, but entity, grouping, basis, and at-risk facts matter. A sale-year passive-loss reconciliation should not be used as a substitute for computing the gain character. Likewise, a partial asset disposition may create a separate tax result when an asset is actually retired; it is not a generic way to reduce future recapture. A transfer at death can change basis under Section 1014, but ownership and estate facts must be reviewed rather than promised as a universal exit.

Documents to bring and common failure points

Bring the engineering study and detailed asset schedule; original and later closing statements; improvement and retirement invoices; all filed Forms 4562, 4797, and 3115; the depreciation ledger by year; the purchase-and-sale agreement and draft allocation; exchange or installment documents, if any; and passive-loss carryforwards. AE can compare the tax cost of a sale, exchange, or hold against the deductions you actually used—not a generic “recapture rate” estimate.

• Applying a 25 percent rate to every 15-year item: the class can contain Section 1245 and Section 1250 property, and accelerated depreciation on Section 1250 can create ordinary recapture.
• Using original cost instead of adjusted basis: depreciation allowed or allowable, improvements, and prior dispositions change gain.
• Applying depreciation from one asset against another asset's gain: recapture is initially calculated by property, with subsequent return-level character rules.
• Assuming every exchange defers every component: Section 1031 eligibility and Sections 1245/1250 recapture are separate tests.
• Assuming cost segregation must win: deduction usability, study cost, financing, hold period, sale allocation, and the seller's actual tax rates can reverse the result.

Where the computation appears on the return

Form 4797 Part III starts the Section 1245 and 1250 recapture calculation. Ordinary amounts move to Part II; remaining qualifying Section 1231 gain or loss is netted in Part I, with any net gain and unrecaptured Section 1250 amounts carried through the applicable Schedule D worksheets. An entity return or partner/shareholder K-1 can add another reporting layer. A simple capital-gain entry without an asset-level Form 4797 analysis is a reason to review the sale-year filing.
