Final answer:
a. Stan's taxable income is $4,500. b. Stan's net unearned income is $4,500. c. Stan does not have any earned taxable income. d. Stan's tax for 2018 is $450.
Step-by-step explanation:
a. To calculate Stan's taxable income for the purpose of the tax on a child's unearned income, we need to consider the threshold amount. In 2018, the threshold amount is $2,100. If a child's unearned income exceeds this amount, it is subject to tax. Stan's interest income is $4,500, which is higher than the threshold amount. Therefore, Stan's taxable income is $4,500.
b. Net unearned income is calculated by subtracting certain deductions and the threshold amount from the child's unearned income. In this case, there are no deductions to consider since Stan's unearned income is interest income only. Thus, Stan's net unearned income is $4,500.
c. Earned taxable income refers to income that a child earns through employment or self-employment. Since Stan's income is from interest and not earned through employment, he does not have any earned taxable income.
d. To calculate Stan's tax for 2018, we need to determine the tax rate for his unearned income. For a child with a net unearned income of $4,500, the tax rate is 10%. Therefore, Stan's tax for 2018 is $4,500 x 10% = $450.
