What this line means
The net gain or loss from casualties and thefts of business and income-producing property. If insurance proceeds exceed the adjusted basis of the destroyed property, you have a gain. If the unreimbursed loss exceeds any gains, you have a net loss. Gains flow to Form 4797 for further classification. Losses reduce your business income directly.
Does this apply to you?
- You had a net gain or loss from business property casualties after all calculations in Section B
- You need to determine where the gain or loss is reported on your other tax forms
- You are completing Section B and have reached the final calculation
Easy to overlook
Business casualty gains involve Section 1231 netting Gains from business casualties are Section 1231 gains, which receive favorable long-term capital gains rates if your total Section 1231 gains exceed losses for the year. But Section 1231 gains are subject to a five-year lookback rule — if you had net Section 1231 losses in the prior five years, current gains are recharacterized as ordinary income up to the amount of those prior losses. 1 IRS Publication 544 — Sales and Other Dispositions of Assets
Depreciation recapture applies to gains on depreciable property If the destroyed business property was depreciable (equipment, vehicles, buildings) and insurance proceeds exceed the adjusted basis (cost minus accumulated depreciation), the gain up to the amount of depreciation previously claimed is taxed as ordinary income, not capital gains. This recapture under Section 1245 or Section 1250 catches filers who expect capital gains treatment on the entire gain. 2 IRS Form 4684 instructions — Line 27
Watch out for this
Reporting a business casualty loss directly on Schedule C without completing Form 4684. All casualty and theft losses on business property must be calculated through Form 4684, Section B first. The net result on line 27 then flows to the appropriate form (Form 4797, Schedule C, or Schedule E). Skipping Form 4684 omits required calculations and documentation.
