Sally has taxable income of $160,000 as of November 30 of this year. She wants to sell a Rodin sculpture that has appreciated $90,000 since she purchased it six years ago, but she does not want to pay more than $15,000 of additional tax on the transaction. Sally also owns various stocks, some of which are currently worth less than their basis. How will the gain on sale of the Rodin sculpture be taxed? How can Sally achieve her desired result of not paying more than $15,000 of additional tax on the transaction?
