Note:

• Your actual property loss: The IRS requires you to use the lesser of your property’s tax basis or the decrease in fair market value to determine the deductible amount of your casualty loss. In most cases, your tax basis is equal to the amount that you originally paid for your property.
• Deductible property loss: Once you have determined your actual loss, you must then reduce it by $100. This $100 reduction is applied to each separate casualty event.
• if the casualty loss is not the result of a federally declared disaster, you must itemize your deductions to claim the loss.
