The scope of eligible casualty and theft loss tax deductions will narrow dramatically starting in 2018.

My mother had a trusted caregiver steal her car, almost $100,000 in cash, tens of thousands of dollars in silver and antiques and illegally use her identity to the tune of $42,000. (I’m still fighting with Chase Bank on a credit card with them.)

Thank goodness she could take a tax deduction for those losses because she needed to cash in some annuities and a pension plan to get the cash she needed to replace the money stolen. Those events were all taxable.

If this had all happened in 2018, it wouldn’t have been deductible on her return.

I recently had a consultation with a new client who had been taken by an alleged crook. He had given him money for assets that didn’t seem that he ever received. There are already criminal charges pending against the bad guy, but since this is all so new and he’s not sure if indeed the guy has his assets squirreled away or there are assets available to give him at least a partial reimbursement, there’s a big question.

Can he take a deduction for 2017? If so, he’s got a big deduction on his return. Or, does he need to wait until 2018? If so, there is no deduction.

Timing, in this case, is very important.

So, just in case you find yourself in a similar spot in 2017, here are some of the factors that the IRS looks at when determining when a theft loss can be deducted.

If you reasonably expect that you will receive a recovery from third parties, such as insurance companies or others, and there is substantial possibility that such claims will be decided in your favor, you don’t have a loss. However, the court case of SS White Dental says that you are not required to be an “incorrigible optimist.” If the potential for recovery is remote or nebulous, then there is a loss.

The law does not require that damages be determined with “mathematical certainty” but does require that damages be capable of measurement “based upon known reliable factors with undue speculation.”

It’s recommended that you provide the IRS with an independent, expert opinion as to the amount of unrecoverable loss.

If you have a theft or casualty loss with an uncertain date, try to pull it into 2017. That way it’s deductible. Otherwise, you lose.
