Amount
Taxable Income $98,000
a.Federal tax liability = 24%*98,000 = $23,520( in case of unmarried individuals in the slab of income over $82500 as per the current tax slab) since nothing is mentioned about the martial status of Lillian.
b.Marginal tax rate from tax rate schedule is 24% for single tax payer in the income slab of $82501-$157500
Average tax rate = $23,520/$98,000 = 24%
Effective rate = $23520/($122,000 +$4100 – $9000) = 20.08%
c.From tax planning purposes, the marginal tax rate is most important because it measures the tax savings from each additional $1 deduction.
