The question is incomplete. The complete question is :
Tammy, a resident of Virginia, is considering whether to purchase a $100, 000 North Carolina bond that yields 4.6% before tax. She is in the 35% Federal marginal tax bracket and the 5% state marginal tax bracket. Tammy is aware that State of Virginia bonds of comparable risk are yielding 4.5%. Virginia bonds are exempt from Virginia tax, but the North Carolina bond interest is taxable in Virginia. Tammy can deduct all state taxes paid on her Federal income tax return. Â In your analysis, assume that the bond amount is $100,000.If required, round your computations and answers to the nearest dollar. Determine the after tax income from each bond. Virginia Bond: $ 4, 600 North Carolina Bond: $ 4, 451 Which of the two options will provide the greater after-tax return to Tammy? Virginia bond
Solution :
Assuming that the bond amount is  $100,000.
After the tax income from the Virginia bond is given by:
= 100,000 x 4.5%
= $ 4500
After the income tax from the North Carolina bond :
= (100,000 x 4.6%) x (1-5%) + (100,000 x 4.6% x 5% x 0.35)
= $ 4451
Therefore the Virginia bond will give an after tax higher return.
