This study offers an alternative method of calculating marginal personal tax rates through the pairing of nontaxable (industrial development and pollution control) and taxable corporate bonds. This procedure is shown to produce matched bond pairs that are comparable. Two hundred pairs of bonds are examined from the second quarter of 1973 through the second quarter of 1983. Testing of the marginal tax rate relationships indicates that the marginal personal tax rate is less than the corporate statutory tax rate.

Miller and Scholes (1978) hypothesize that the marginal tax rate on dividend income may be less than the marginal rate of tax on capital gains. Their hypothesis is dependent upon individuals utilizing existing provisions of the Code which serve to reduce the taxation of dividends. In this study, estimates of the marginal and effective rates of tax on dividend income for the year 1979 are presented using the Statistics of Income sample of returns. The average marginal rate of tax on dividend income is estimated to be 40%, while the average effective rate of tax is estimated to be 30%.
