You can deduct a casualty loss, but under the law, a personal casualty loss is determined by taking the smaller of:
- The cost or other basis of the property (reduced by any insurance reimbursement), or
- The decline in fair market value of the property as measured immediately before and after the casualty (reduced by any insurance reimbursement).
The cost of repairs may be used to measure the decline in fair market value, but you still have to calculate FMV before and after the event because TurboTax will ask for those two numbers. Be ready to do some math.
When the cost of repairs is determined to be a fair measure of the decline in fair market value, then all you have to do is take the fair market value before the casualty and reduce it by the cost of repairs to arrive at the fair market value after the casualty. .
