GENERAL SUMMARY 333 for each dependent. Corporations are not granted an ex- emption. The corporation franchise tax is based upon capital and surplus, the rate being $0.50 per $1,000. As a result of a court interpretation, surplus is construed to be the difference between capital and total assets, and the tax in practice is essentially based on assets. Missouri levies a special tax on foreign insurance companies. The rate is 2%, and the tax base 1s the amount of premiums received in the state or on account of business done in the state. Express companies are taxed by means of a special tax on gross receipts. Missouri levies a gasoline tax of two cents per gallon, the lowest rate now in effect in the United States. Motor vehicle license rates are also moderate. Cities are given authority to levy gasoline taxes and motor vehicle license taxes for local purposes. State AND LocaL Tax REVENUES The most significant changes in recent years in the sources of state revenue are the decline in the relative importance of the general property tax and the increasing volume of receipts from motor vehicle taxation. Inheritance tax col- lections amounted to more than $3 million in 1928, an amount more than 509%, greater than the collections in either of the two years immediately preceding. Income tax collections in 1928 amounted to $3.7 million, or 10.8%, of the tax revenues of the state. In 1926 the receipts from the income tax amounted to $4.3 million, the largest amount that has been obtained from this source in any year. Gasoline tax receipts amounted to $6.6 million in 1928, and $3.6 million of state revenue was obtained from motor vehicle licenses. For each year of the period 1923 through 1928, during which both the gasoline tax and motor vehicle license tax were in effect, the combined receipts from the two sources amounted to at least 449, of the total tax revenue of the state. Local tax receipts in Missouri amounted to $104 million in 1928, as compared with $78.6 million in 1922. More than 909 of local tax revenues is derived from the general prop- erty tax. Per capita local taxes amounted to $22.73 in 1922
