Demarco and Janine Jackson have been married for 20 years and have four children who qualify as their dependents (Damarcus, Janine, Michael, and Candice). The couple received salary income of $115,000, qualified business income of $11,500 from an investment in a partnership, and they sold their home this year. They initially purchased the home three years ago for $207,500 and they sold it for $257,500. The gain on the sale qualified for the exclusion from the sale of a principal residence. The Jacksons incurred $16,800 of itemized deductions, and they had $3,700 withheld from their paychecks for federal taxes. They are also allowed to claim a child tax credit for each of their children. However, because Candice is 18 years of age, the Jacksons may claim a child tax credit for other qualifying dependents for Candice. Please show all work. (CURRENT TAX YEAR)
