Question

Campbell, a single taxpayer, earns $400,000 in taxable income and $2,000 in interest from an investment in State of New York bonds. (Use the U.S. tax rate schedule.) Required: How much federal tax will she owe? What is her average tax rate? What is her effective tax rate? What is her current marginal tax rate?

Answer 1

Answer: Campbell will owe $115,858.25 in federal income tax this year computed as follows:

$115,858.25= $45,353.75+ 33% x ($400,000 - $186,350)).

Campbell's average tax rate is 28.96 percent.

Average Tax Rate = TotalTax / TaxableIncome = $115,858.25 / $400,000 = 28.96

Campbell's effective tax rate is 28.82 percent.

Effective tax rate = TotalTax / TotalIncome = $115,858.25 / ($400,000 + $2000) = 28.82

Campbell is currently in the 33 percent tax rate bracket. Her marginal tax rate on deductions up to $213,650 will be 33 percent. However, her marginal tax rate on the next $5,100 of income will be 33%, and income earned over $405,100 will be 35 percent. Income earned in excess of $406,750 will be taxed at 39.6%.
