Form 4797: Sales of Business Property Definition: What It Is and How to File

Definition · Updated November 1, 2025

What Is Form 4797 — Sales of Business Property?

Form 4797, “Sales of Business Property,” is an IRS tax form used to report gains and losses from the sale, exchange, or involuntary conversion of property used in a trade or business or held to produce rental or royalty income. Typical items reported on Form 4797 include depreciable business equipment, commercial real estate, rental property, and interests in natural‑resource properties (oil, gas, mineral). The form also handles depreciation recapture and certain “recapture” amounts from Section 179 expensing and luxury auto limits. (IRS Instructions for Form 4797; Investopedia)

Key takeaways

– Use Form 4797 when you sell or dispose of business property, rental real estate treated as business property, or other nonpersonal assets used to produce income.
– The form determines ordinary income from depreciation recapture and net gains (or losses) from business property dispositions.
– Parts of Form 4797 are organized by the type of property and holding period; correct placement is critical because some gains are treated as ordinary income while others may be capital gains. (IRS; Investopedia)

Who can file Form 4797?

– Individuals (sole proprietors), partnerships, S corporations, C corporations, estates, and trusts file Form 4797 when they have reportable sales or dispositions of business/rental property.
– If a flow‑through entity (partnership or S corp) sells property, the gain or loss is reported at the entity level and flows through to partners/shareholders on Schedule K‑1; those owners may have tax consequences and must report the items on their returns as instructed. (IRS; Investopedia)

Which transactions are reported on Form 4797?

– Sales or exchanges of property used in a trade or business (including many rental properties).
– Involuntary conversions (other than casualty or theft) of property used in a trade or business.
– Dispositions subject to depreciation recapture under sections such as 1245 and 1250.
– Recapture under Section 179 and section 280F(b)(2) when business use drops below 50%. (IRS Instructions for Form 4797)

Form 4797 — the parts and what belongs where

– Part I: Sales or exchanges of property used in a trade or business and involuntary conversions (other than casualty or theft). Most depreciable property held more than one year is reported here. (IRS)
– Part II: Ordinary gains and losses — typically covers property held one year or less and other dispositions treated as ordinary gain or loss. (Investopedia; IRS)
– Part III: Gain from disposition of property under sections 1245, 1250, 1252, 1254, and 1255 — this part handles certain gains that may be capital gains but require recapture analysis (e.g., section 1245 recapture of depreciation on equipment). (IRS; Investopedia)
– Part IV: Recapture amounts under Section 179 and 280F(b)(2) (when business use drops to 50% or less). (IRS)

Practical steps — how to prepare and file Form 4797

1. Gather documentation
– Closing statement or sales contract (showing sale price)
– Purchase documents and records of improvements (to establish original cost and adjusted basis)
– Depreciation records (total depreciation taken to date)
– Date acquired and date sold (holding period)
– Any allocation of sales proceeds (land vs. building, personal vs. business use portions).
2. Determine adjusted basis
– Adjusted basis = original cost + capital improvements − total depreciation and other adjustments. This basis is used to compute gain or loss. (IRS)
3. Classify the property and the transaction
– Is it depreciable business property, a capital asset, or property with special recapture rules (section 1245/1250)?
– Was the property held more than one year (long‑term) or one year or less (short‑term)?
4. Compute gain or loss
– Gain (or loss) = Amount realized (sales price − selling expenses) − adjusted basis.
– Identify how much of the gain is attributable to depreciation (potential recapture).
5. Complete the appropriate Part(s) of Form 4797
– Enter details of each disposition in the appropriate part (I, II, III or IV). Use additional forms/worksheets in the Instructions as needed (for example, to calculate section 1245 recapture).
6. Transfer amounts to the correct places on your tax return
– Ordinary gains from recapture usually flow to ordinary income lines on Form 1040 (or corporate return). Certain net gains may flow to Schedule D or be reported elsewhere depending on the nature of the gain. Follow Form 4797 instructions for lines to transfer to Form 1040, Schedule D, or other forms. (IRS Instructions for Form 4797)
7. Attach Form 4797 to your tax return
– File Form 4797 with your tax return (Form 1040, Form 1120, etc.) for the year in which the disposition occurred. Keep records for at least three years (or longer per IRS guidance).

Difference between Schedule D and Form 4797

– Schedule D (Form 1040) reports capital gains and losses from sales of capital assets (personal investments such as stocks, bonds, investment real estate held as capital assets).
– Form 4797 is specifically for property used in a trade or business (including many rental properties) and handles depreciation recapture and ordinary‑income treatment where required.
– If the disposition produces a capital gain that is reportable, amounts from Form 4797 may ultimately be reported on Schedule D (per the Form 4797 instructions). However, many gains reported on Form 4797 are treated as ordinary income (due to recapture) and do not go to Schedule D. (IRS; Investopedia)

Should you use Form 8949 or Form 4797?

– Form 8949 is used to report sales and other dispositions of capital assets (primarily investments) and to reconcile amounts to 1099‑B reporting from brokers.
– Most business property dispositions belong on Form 4797, not Form 8949. One exception: if you are deferring capital gains via certain transactions or if the disposition is treated as a capital asset sale and it requires Form 8949 reporting (for example, certain capital‑asset gains reported after Form 4797 calculations), follow the instructions on both forms to determine where to report. (IRS Instructions for Form 8949; Investopedia)

How to limit or defer capital gains tax on a business sale

You generally cannot permanently “avoid” capital gains tax on a business sale without disposing of the asset in a way that creates ordinary income or qualifies for specific exclusions, but you can sometimes defer or reduce immediate tax through certain strategies. Common options include:
– Like‑kind exchange (Section 1031) for real property: If you reinvest proceeds from the sale of qualifying business or investment real estate into like‑kind replacement real property within IRS timeframes, you may defer recognition of gain. (See IRS guidance on like‑kind exchanges and Form 8824.)
– Qualified Opportunity Funds (Opportunity Zones): By investing capital gains into a Qualified Opportunity Fund within required timeframes, you may defer tax on part or all of those gains and potentially receive step‑ups in basis for gains held long term. (IRS Opportunity Zones guidance.)
– Installment sale reporting: Spreading the gain over multiple years under an installment sale (Form 6252) can defer recognition and potentially keep you in a lower tax bracket in a given year. (IRS Publication and Form 6252 instructions.)
– Section 121 home sale exclusion: If part of the property sold was your primary residence and you meet the ownership/use tests, you may exclude up to $250,000 ($500,000 married filing jointly) of gain; special rules apply when property was partly used for business or rental. (IRS Publication 523.)
– Cost‑basis management and tax planning: Properly documenting improvements, depreciation, and basis adjustments can reduce taxable gain or affect the portion treated as ordinary for recapture purposes.
Before pursuing any of these, consult a tax advisor; eligibility and tax consequences depend on facts, property type, and current tax law. (Investopedia; IRS)

Common pitfalls and best practices

– Misclassifying property: Putting a disposition in the wrong part of Form 4797 can change whether gain is ordinary or capital. Use the Form 4797 instructions and, if needed, professional help.
– Ignoring depreciation recapture: Depreciation claimed reduces basis and often converts part of the gain to ordinary income under recapture rules (Section 1245/1250).
– Failing to allocate sales price correctly: For real estate, properly allocating between land (nondepreciable) and building (depreciable) matters for basis and depreciation recapture.
– Not keeping records: Maintain purchase documents, depreciation schedules, improvement receipts, and sale documents for several years.
– Missing filing connections: Some amounts from Form 4797 may affect Schedule D or ordinary income lines—follow the transfer instructions exactly.

The bottom line

Form 4797 is the IRS form for reporting sales, exchanges, and involuntary conversions of business and income‑producing property. It is critical for calculating depreciation recapture and for determining whether gains are taxed as ordinary income or capital gain. Correctly classifying the property and transaction, accurately computing adjusted basis and depreciation recapture, and following the Form 4797 instructions are essential. Consider consulting a tax professional when large amounts, complex recapture calculations, or deferral strategies (like 1031 or Opportunity Zone investments) are involved. (IRS; Investopedia)
