“ Because of pertinent congressional legislation in the banking field, we find it unnecessary to reach the constitutional question of whether today national banks should be considered nontaxable as federal instrumentalities.
As will be seen, Congress has been far from reluctant to pass legislation in the banking field. There are important committees on banking and currency in both Houses which continually monitor banking affairs and propose new legislation when changes are felt to be needed. ”

“ A long line of subsequent decisions by this Court has firmly established the proposition that the States are without power, unless authorized by Congress, to tax federally created, or, as they are presently called, national, banks. ”

“ Now this Court is asked to change what legislative history and prior decisions have established is the precise meaning of an Act of Congress. This we cannot do. For, as we pointed out above, the banking field has traditionally been an area of particular congressional concern marked by legislation responsive to new problems. This can be illustrated by the history of § 548 alone. It was originally passed in 1864 because the 1863 Currency Act [4] contained no provision for state taxation of national banks or their shares. ”
