State inheritance taxes, sufficiently large to accomplish the desirable result, will be evaded by change of residence to another state.

A Federal tax could be raised to a much higher level without prompting the two possible methods of evasion--one of which would be the legal transfer of the property during lifetime, and the other a complete change of residence to some foreign country.

This second method of evasion would not constitute a serious danger, because of the equally severe inheritance laws of foreign countries.

The tax at its highest level could be placed without danger of evasion at as much as twenty per cent.

The United Kingdom now raises almost $100,000,000 of revenue from the source; and a slightly increased scale of taxation might yield double that amount to the American Treasury, a part of which could be turned into the state Treasuries.
There has been associated with the graduated inheritance tax the plan of a graduated income tax; but the graduated income tax would serve the proposed object both less efficiently and less equitably.
