The rules for writing off personal casualty losses on a tax return have changed for 2018 to 2025. Specifically, taxpayers generally can’t deduct losses unless the casualty event qualifies as a federally declared disaster. (The rules for business or income-producing property are different.) Another factor that now makes it harder to claim a casualty loss is that you must itemize deductions to claim one. For 2018 to 2025, fewer people will itemize, because the standard deduction amounts have been significantly increased. We can help you navigate the complex rules.
