Answer:
Since we are not given any specific year, I will use the 2020 tax schedule:
Marc and Michelle's gross income = Marc's and Michelle's salaries + interest from corporate bonds = $70,400 + $14,400 + $1,300 = $86,100
they should choose the standard deduction since it is higher than their itemized deductions = ($24,400)
<u>contribution to IRA = ($3,300)</u>
Marc and Michelle's taxable income = $58,400
Marc and Michelle's tax liability = $1,975 + [12% x ($58,400 - $19,750)] = $6,613
Alimony payments are not longer tax deductible and interests on municipal bonds is not taxable.
Since their income tax withholdings exceed their tax liability, they should get a refund for $6,665 - $6,613 = $52
Also, since they are allowed a $2,000 child tax credit, but they do not owe any more taxes, they are entitled to a $1,400 refund.
Total refund for 2020 = $1,452.
