Filing the Claim. You can only write off losses if you itemize deductions. Casualty and theft losses are a 2 percent deduction, like unreimbursed employee expenses and the cost of hiring a tax-prep firm.hen you have to deduct $100 from the amount. If you claim multiple car losses, you deduct $100 from each loss. Add up all your total losses -- including any other thefts, fire damage to your house, etc. -- and subtract 10 percent of your adjusted gross income from the total. Whatever you have left is deductible.
