Ms. Busch has gathered these data about her finances:
Salary 140,000
Taxable interest received 2,500
Municipal bond interest received 15,000
Total itemized deductions 8,000
The personal exemption is $3,700. The standard deduction for a
single filer is $5,800.
a. Her tax
b. Her average effective tax rate
c. Her average tax rate
d. Her marginal tax rate
e. Her accountant discovers a previously omitted personal
deduction of $800. By how much does her federal tax liability fall
with that addition?
f. Amazingly enough, the accountant now discovers a $250 credit
omitted from previous calculations (but after discovering the $800
in part e.). By how much does her federal tax liability fall
because of this credit?
