Prior to tax reform, you were able to deduct most losses for uninsured casualty, disaster and theft losses. Under tax reform provisions, deductions for casualty and theft losses have changed for tax years 2018 through 2025. If you suffered a casualty or theft loss as a result of an unusual event like a flood, fire or some other unforeseen event, you can deduct the loss if the casualty is within a federally declared disaster area or the theft occurred as a result of a federally declared disaster.
The IRS may provide additional special tax provisions to help recover financially from the impact of a disaster when the federal government declares a certain location to be a major disaster area. Depending on the circumstances, relief may be additional time to file returns and pay taxes.
