Dana is an attorney who specializes in family law. She uses the cash method of accounting and is a calendar-year taxpayer. Last year, she represented a client in a lawsuit and billed the client $5,000 for her services. Although she made repeated attempts, Dana was unable to collect the outstanding receivable. Finally, in November of the current year, she finds out that the individual has moved without leaving any forwarding address. Dana’s attempts to locate the individual are futile. What is the amount of deduction that Dana may take with respect to this bad debt?
