GENERAL SUMMARY 341 Motor vehicle taxation in Missouri is lighter than in many other states. The ratesfor thelicense tax are moderate, and the two cent tax on gasoline is very low as compared with the average for the United States. Many motor vehicles escape taxation under the general property tax. A number of cities levy a gasoline tax and collect motor vehicle license taxes, with the result that motor vehicle taxation varies throughout the state. SOURCES OF ADDITIONAL REVENUE Any estimate of the additional state revenues that will be needed during the next few years must depend largely on the position taken concerning (1) the financing of capital re- quirements by means of a bond issue as compared with current revenues; (2) the amount of additional maintenance appropriations to institutions of higher learning, including teachers’ colleges; (3) additional state aid for public school purposes; and (4) additional state support for conservation of the public health and care and treatment of the mentally defective and feebleminded. As has been seen, there is an administrative reason for continuing the state tax on property. Another reason is the impossibility of accurately estimating the receipts from the income tax, if the system of administration is changed and intangible property is exempted from the general property tax. A form of classified property tax providing for low rates on intangible property does not seem to offer a solution of the problem of reaching this form of property for taxation. The experience of Kansas in recent years was so unfavorable, that the low rate taxes on intangibles were abandoned. The yield of the Missouri income tax may be augmented in three ways: (1) by improving the administration; (2) by a broadening of the tax base; and (3) by increasing the rates. Improving the administration offers certain possibilities for increasing the yield, although its effect cannot be accurately estimated in advance. A broadening of the tax base, so as to include all dividends in the personal income tax base, would increase the yield, but,unless it were reasonably certain
