Compute the difference between accumulated savings (net of taxes) for $15,500 (pretax) placed in bonds yielding 5.5% in a qualified pension versus an investment in a municipal bond yielding 3.5%. The municipal bond sum deposited was made with after-tax dollars on the same pretax amount. The marginal tax rate was 28%. Assume that the sums were accumulated for 30 years and the pension was liquidated at that time.
