How to File IRS Form 4797: Sales of Business Property

Selling something the business used is reported differently from selling an investment, and this is where those sales go.

The treatment depends on what the asset was, how long it was held, and how much depreciation has been claimed on it, which means the answer comes from the fixed asset register rather than from the sale documents.

This covers which property belongs here, what each part of the form deals with, how the figures are built, how depreciation already claimed changes the character of the gain, and how it all reaches the rest of the return.

When a business sells property it used in operations, equipment, vehicles, buildings, or land, the gain or loss is not simply a capital gain or loss. Depreciation recapture rules and Section 1231 may turn what looks like a capital gain into ordinary income. Form 4797, Sales of Business Property, is where all of this is calculated and reported.

What Types of Property Go on Form 4797?

• Depreciable business property sold at a gain (machinery, equipment, vehicles, computers)
• Real property used in a trade or business
• Capital assets held in connection with a trade or business
• Involuntary conversions from theft, casualty, or condemnation
• Livestock held for draft, breeding, dairy, or sporting purposes

The Three Parts of Form 4797

Part I, Property Held More Than 1 Year (Section 1231 Transactions)

Section 1231 assets are business assets held for more than one year. The netting rule: if total Section 1231 gains exceed Section 1231 losses for the year, the net gain is treated as long-term capital gain, taxed at preferential rates. If Section 1231 losses exceed gains, the net loss is treated as an ordinary loss, fully deductible without limitation.

Pro Tip: The Section 1231 lookback rule: if you had net Section 1231 losses in any of the previous 5 years, your current year Section 1231 gains are recharacterized as ordinary income to the extent of those unrecaptured losses.

Part II, Ordinary Gains and Losses (Recapture, Sections 1245 and 1250)

Depreciation recapture converts what would otherwise be capital gain into ordinary income, to the extent of prior depreciation deductions. Two main recapture rules:

Section 1245 Recapture, Personal Property

Applies to depreciable personal property (equipment, vehicles, machinery, computers, and even certain intangibles). ALL depreciation previously taken is recaptured as ordinary income on sale, up to the amount of gain. If the sale price exceeds the original cost, the excess is Section 1231 gain.

Example: Machine purchased for $100,000, accumulated depreciation $70,000, sold for $80,000. Adjusted basis = $30,000. Gain = $50,000. Section 1245 recapture = $50,000 (all gain is ordinary income up to depreciation of $70,000).

Section 1250 Recapture, Real Property

Applies to depreciable real property (buildings). Under current law (post-1986), straight-line depreciation is required for real property, so there is typically no Section 1250 recapture in the traditional sense. However, a special rule, unrecaptured Section 1250 gain, taxes the straight-line depreciation portion at 25% (rather than the 20% long-term capital gains rate) when the property is sold.

Part III, Gain from Disposition of Property Under Sections 1245, 1250, 1252, 1254, and 1255

Part III is a detailed computation section where you calculate the recapture amounts that feed into Part II. It identifies the amount of gain attributable to depreciation for each property sold.

Step-by-Step: Completing Form 4797

• List each property in the appropriate Part based on the type and holding period.
• For each property: enter description, date acquired, date sold, gross sales price, depreciation allowed since acquisition, cost/basis, and gain or loss.
• Compute Section 1245 recapture in Part III and carry the recapture amount to Part II.
• Net all Section 1231 transactions in Part I.
• Transfer ordinary gains from Part II to Form 1040 (or 1120) as ordinary income.
• Transfer any net Section 1231 gain from Part I to Schedule D as long-term capital gain.

Interaction with Schedule D

Net Section 1231 gains flow to Schedule D, Line 11. Net Section 1231 losses do not go to Schedule D, they are ordinary losses deducted directly. Unrecaptured Section 1250 gain is tracked on a separate worksheet and ultimately taxed at 25% on Schedule D.
