How recapture works for partially business-used property
When property is used partly for business and partly for personal purposes, depreciation recapture generally applies only to the business-use portion. The Internal Revenue Service Publication 544 by the Internal Revenue Service explains that you must allocate basis and depreciation between the business and personal portions, then treat the business portion of gain consistent with tax code recapture rules. Depreciation taken or that could have been taken against the business portion reduces adjusted basis and can convert part of a sale gain into income that is taxed differently than capital gain.
Different rules for types of property
Two statutory rules matter. Section 1245 applies mainly to tangible personal property and certain depreciable assets and requires that depreciation be recaptured as ordinary income to the extent of prior depreciation. Section 1250 governs depreciable real property; when straight-line depreciation was used, recapture is limited and any unrecaptured Section 1250 gain may be taxed at a maximum 25 percent rate rather than ordinary rates. The Internal Revenue Service Publication 527 by the Internal Revenue Service discusses these distinctions in the context of rental and residential rental property.
Causes, consequences, and real-world nuance
The cause is mechanical: depreciation lowered taxable income during ownership, so the tax code recaptures some benefit on sale. Consequences include higher tax liability than a pure capital gain, the need for careful historical records of depreciation claimed, and potential loss of home-sale exclusion for depreciation amounts when part of a residence was used for business. Publication 523 by the Internal Revenue Service clarifies that depreciation taken on a home office is not excludable under the home sale exclusion rules and must be recognized on sale.
Social and territorial nuances matter. Small landlords, gig-economy workers using portions of homes for commerce, and owners of seasonal or rural rental cabins may face disproportionate compliance burdens. State tax treatment can diverge from federal rules, producing additional planning complexity for owners in different jurisdictions. Practical outcomes therefore depend on accurate allocation, the nature of the asset, and both federal and state law.
