342 THE FISCAL PROBLEM IN MISSOURI that income from other intangibles was being reached for taxation, such a broadening of the base would involve dis- crimination against dividends received from domestic cor- porations and foreign corporations doing business within the state. There is no satisfactory answer to the question concerning the changes in income tax rates that would have to be made, if all of the additional revenues needed were to be obtained from the income tax. This would be particularly true, if it were decided to adopt moderately progressive rates on personal incomes and a flat rate on income from intangible property. The receipts from the income tax vary in accor- dance with business conditions, and it is by no means certain that a flat rate of 29% in all incomes for 1931 would produce twice the amount of revenues obtained in 1928 or 1929, even though a centralized system of administration were adopted. The best policy would therefore seem to be to obtain a part of the increased revenues desired from some tax with a high degree of fiscal adequacy and to increase the income tax rates moderately. Although progressive rates on personal incomes may be desirable, it does not follow that Missouri should adopt steeply progressive rates. There are no sound reasons why corporation income tax rates should be progressive. Natural differences in size as between industries tend to make a progressive rate schedule inequitable when applied to cor- porate income. The corporation franchise tax is essentially a tax on assets and, disregarding certain technical aspects, it is in effect an extra tax on property, including intangible as well as tangible property. The continuance of the tax at existing rates seems to be justified, primarily because of its fiscal adequacy. Since a tax is levied on personal and corporation incomes, there does not appear to be any good reason why a general sales or turnover tax should be considered. A number of states adjoining Missouri tax cigarette sales, and almost one third of the states have enacted laws pro- viding for tobacco taxes. Regardless of the objections that might be raised, a tax on cigarette sales has a degree of fiscal adequacy that many other taxes do not possess. One of the
