Two years ago, Green Corporation, an accrual-basis taxpayer, sold merchandise on credit to John, an individual. Green’s account receivable from John was $20,000. Last year, John filed for bankruptcy, and Green was notified that it could expect to receive 20 cents on the dollar. Accordingly, Green took a $16,000 bad debt deduction on last year’s tax return. In June of the current year, Green received a $6,000 payment from John in final settlement of the debt. How should Green account for the payment in the current year?
