Demarco and Janine Jackson have been married for $20$ years and have four children who qualify as their dependents $($Damarcus$,$ Jasmine, Michael, and Candice$).$ The Jacksons file a joint tax return. The couple received salary income of $$105,000$ and qualified business income of $$10,000$ from an investment in a partnership, and they sold their home this year. They initially purchased the home three years ago for $$200,000,$ and they sold it for $$250,000.$ The gain on the sale qualified for the exclusion from the sale of a principal residence. The Jacksons incurred $$16,500$ of itemized deductions, and they had $$4,000$ 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 at year$-$end, the Jacksons may claim a child tax credit for other qualifying dependents for Candice.
