A taxpayer is trading in an automobile used solely for business purposes for another automobile to be used in his business. The automobile originally cost $35,000 and he has taken $12,000 in depreciation. The old automobile is currently worth $20,000 and the new automobile the taxpayer wants in exchange is worth $20,000. No other cash or property is exchanged in the transaction. What is the gain or loss realized and recognized by the taxpayer on this transaction, and what is the taxpayers basis in the new automobile?
