Ms. Zelda has decided to invest $75,000 in state bonds. She could invest in State A bonds paying 5 percent annual interest or in State R bonds paying 5.4 percent annual interest. The bonds have the same risk, and the interest from both is exempt from federal income tax. Because Ms. Zelda is a resident of State A, she wouldn’t pay State A’s 8.5 percent personal income tax on the State A bond interest, but she would pay this tax on the State R bond interest. Ms. Zelda can deduct any state tax payments in the computation of her federal taxable income, and her federal marginal rate is 32 percent. Should Ms. Zelda invest in the State A or the State R bonds?
