Tax and other financial considerations after a natural disaster(2)

The year 2011 was a tough one for natural disasters, with hurricanes soaking the Atlantic coast, tornadoes wreaking havoc in Southern and Midwestern states and wildfires hitting Texas, among other events. If you were affected by a natural disaster this year, you should be aware of Internal Revenue Service rules on casualty losses, as well as other financial considerations. The Minnesota Society of Certified Public Accountants (MNCPA) provides some perspective. 

What qualifies for a deduction?
Under Internal Revenue Service rules, you are allowed to deduct a casualty loss that is the result of a disaster, but some of the related rules serve to significantly whittle down the amount you can deduct. First, consider what is eligible for the deduction. A casualty loss is the damage, destruction or loss of property resulting from an identifiable event that is unexpected, sudden or unusual. Damages from natural disasters, such as hurricanes, floods, wildfires and earthquakes are casualty losses. Damage to your home or other property caused by something that is not unexpected, sudden, or unusual, such as accidental breakage of items under normal conditions, progressive deterioration occurring naturally over time, or due to the failure to maintain the property, does not qualify as a casualty loss. If you have suffered a casualty loss to your home, household goods or vehicle due to a disaster, you should be eligible to deduct the amount of that loss on your tax return, less certain required adjustments. (The same is true if you suffer a loss due to a theft.)   

How does the deduction work?
According to the IRS, "If your property is personal-use property, or is not completely destroyed, the amount of your casualty or theft loss is the lesser of: the adjusted basis of your property, or the decrease in the fair market value (FMV) as a result of the casualty or theft.”  

To determine your adjusted basis, start with the basis of the property. Your basis in the property you buy is usually how much it cost you. You then increase or decrease the property’s basis to reflect any improvements you have made to the property or depreciation deductions you have taken for the property. The decrease in the FMV of the property used to determine the casualty loss is the difference between the FMV of the property immediately before the casualty and the FMV of the property immediately after the casualty. The FMV immediately after the casualty frequently will be the salvage value of the property. From the lesser of the adjusted basis of the property or the difference in its FMV, subtract any insurance payment or other reimbursement (for example, compensation for the loss from a government or employer relief program). This is your casualty loss.

For example, suppose flooding heavily damaged your finished basement during a recent hurricane. You have losses on several items that were destroyed by water damage—a washer and dryer, hot water heater, furnace and some furnishings—as well as to the basement walls. Your basis in these items—what you originally spent on them—amounts to $10,000. The fair market value of these items was $9,500 before the disaster and $500 after, making the decrease in the FMV $9,000. Because the decrease in the FMV of the items is less than your adjusted basis in them, you must use the decrease in the FMV in your loss calculation. Your insurance covers you for a maximum of $5,000 in damages, leaving you with a $4,000 casualty loss.

Final steps in the calculation of the deduction
Before deducting this personal property casualty loss on your tax return, there are a couple of last steps you must take. First, you must subtract $100 from every casualty or theft loss you report each year. That lowers the example amount to $3,900. More significant, you must subtract 10 percent of your adjusted gross income from the loss amount to arrive at your final deduction. If your adjusted gross income was, say, $30,000 last year, you would subtract $3,000—10 percent—from your loss amount to arrive at $900 as your allowable deduction. If your adjusted gross income in the example was $39,000 or higher, that 10 percent would wipe out your allowable deduction altogether. 

Other sources of help
For those seeking additional relief, it’s important to be aware that organizations such as FEMA, the Federal Emergency Management Agency, often provide funds and services to those affected by disaster. The agency’s guide, Help After a Disaster, offers an overview of what’s available. In addition, Disaster Recovery: A Guide to Financial Issues—a joint project of the American Institute of CPAs, the American Red Cross and the National Endowment for Financial Education—answers questions on how to minimize the consequences in the first days, weeks and months after a disaster.
