Which event can typically trigger a casualty loss deduction?

A casualty loss deduction is typically associated with events that cause a sudden, unexpected, or unusual loss to personal or business property. Acts of vandalism fit this description because they result in unanticipated damage to property caused by malicious actions. This sudden event allows property owners to claim a casualty loss deduction since the damage is not a normal occurrence and falls outside the scope of routine property depreciation or maintenance.

On the other hand, regular wear and tear, neglect and maintenance issues, and regular property improvements do not qualify as casualty losses. Wear and tear is a gradual decline in condition due to use over time, while neglect and maintenance issues are often the result of a lack of upkeep, both of which do not represent sudden or unusual events. Regular property improvements, likewise, increase the value of a property rather than represent a loss. Thus, acts of vandalism are distinctly categorized as a trigger for casualty loss deductions due to their nature as unexpected and harmful events.
