A qualifying casualty loss on rental property can be deductible, but it is not an ordinary repair line. The loss is generally figured on Form 4684 using adjusted basis, decline in fair market value, and insurance reimbursement rules.
The expense-specific result is below. The shared BAR test, de minimis safe-harbor rule, and source guide live on the deductions hub so they are not repeated on every expense page.
A worked classification for casualty losses
A storm causes $20,000 of measured loss, and insurance pays $14,000. Before other basis and Form 4684 adjustments, the unreimbursed amount is $6,000. A later $18,000 roof replacement is tracked as a separate capital restoration, not another $18,000 casualty deduction.
Records that support this treatment
Keep photos, police or weather reports, appraisals, adjusted-basis schedule, insurance claim and settlement, Form 4684 workpapers, repair contracts, and replacement in-service dates.
Rental casualty property is reported under the Instructions for Form 4684, Section B. That source also covers expected insurance reimbursement and mixed personal and rental property.
Keep the invoice, the decision, and the Schedule E placement together. The broader rental property deductions guide and the Schedule E walkthrough cover the full return.
This is general information for organizing rental records, not tax advice. Elections, entity structure, mixed use, and the exact unit of property can change the answer. Bring the invoice and the underlying facts to a CPA before filing.
