NATIONAL BANK
v.
COMMONWEALTH.
Supreme Court of United States.

*355 Mr. Wills, with a brief of Messrs. Pirtle and Caruth, for the plaintiff in error.
Mr. Albert Pike, contra.
*358 Mr. Justice MILLER delivered the opinion of the court.
In the several recent decisions concerning the taxation of the shares of the National banks, as regulated by sections forty and forty-one of the act of Congress of June 3d, 1864, *359 it has been established as the law governing this court that the property or interest of a stockholder in an incorporated bank, commonly called a share, the shares in their aggregate totality being called sometimes the capital stock of the bank, is a different thing from the moneyed capital of the bank held and owned by the corporation. This capital may consist of cash, or of bills and notes discounted, or of real estate combined with these. The whole of it may be invested in bonds of the government, or in bonds of the States, or in bonds and mortgages. In whatever it may be invested it is owned by the bank as a corporate entity, and not by the stockholders. A tax upon this capital is a tax upon the bank, and we have held that when that capital was invested in the securities of the government it could not be taxed, nor could the corporation be taxed as the owner of such securities.
On the other hand, we have held that the shareholders, or stockholders, by which is meant the same thing, may be taxed by the States on stock or shares so held by them, although all the capital of the bank be invested in Federal securities, provided the taxation does not violate the rule prescribed by the act of 1864.
It is not intended here to enter again into the argument by which this distinction is maintained, but to give a clear statement of the propositions that we have decided, that we may apply them to the case before us.
If, then, the tax for which the State of Kentucky recovered judgment in this case is a tax upon the shares of the stock of the bank, and is not a tax upon the capital of the bank owned by the corporation, the first, second, and third grounds of defence must fail.
There are, then, but two questions to be considered in the case before us:
1. Does the law of Kentucky, under which this tax is claimed, impose a tax upon the shares of the bank, or upon the capital of the bank, which is all invested in government bonds?
2. If it is found to be a tax on the shares, can the bank *360 be compelled to pay the tax thus levied on the shares by the State?
The revenue law of Kentucky imposes a tax "on bank stock, or stock in any moneyed corporation of loan and discount, of fifty cents on each share thereof, equal to one hundred dollars of stock therein, owned by individuals, corporations, or societies."
We entertain no doubt that this provision was intended to tax the shares of the stockholders, and that if no other provision had been made, the amount of the tax would have been primarily collectible of the individual or corporation owning such shares, in the same manner as other taxes are collected from individuals. It is clear that it is the shares owned or held by individuals in the banking corporation which are to be taxed, and the measure of the tax is fifty cents per share of one hundred dollars. These shares may, in the market, be worth a great deal more or a great deal less than their par or nominal value, as its capital may have been increased or diminished by gains or losses, but the tax is the same in each case. This shows that it is the share which is intended to be taxed, and not the cash or other actual capital of the bank.
It is said that there may be, or that there really are, banks in Kentucky whose stock is not divided into shares of one hundred dollars each, but into shares of fifty dollars or other amounts, and that this shows that the legislature did not intend a tax of fifty cents on the share, but a tax on the capital. But the argument is of little weight. What the legislature intended to say was, that we impose a tax on the shares held by individuals or other corporations in banks in this State. The tax shall be at the rate of fifty cents per share of stock equal to one hundred dollars. If the shares are only equal to fifty dollars it will be twenty-five cents on each of such shares. If they are equal to five hundred dollars it will be two dollars and fifty cents per share. The rate is regulated so as to be equal to fifty cents on each share of one hundred dollars.
But it is strongly urged that it is to be deemed a tax on *361 the capital of the bank, because the law requires the officers of the bank to pay this tax on the shares of its stockholders. Whether the State has the right to do this we will presently consider, but the fact that it has attempted to do it does not prove that the tax is anything else than a tax on these shares. It has been the practice of many of the States for a long time to require of its corporations, thus to pay the tax levied on their shareholders. It is the common, if not the only, mode of doing this in all the New England States, and in several of them the portion of this tax which should properly go as the shareholder's contribution to local or municipal taxation is thus collected by the State of the bank and paid over to the local municipal authorities. In the case of shareholders not residing in the State, it is the only mode in which the State can reach their shares for taxation. We are, therefore, of opinion that the law of Kentucky is a tax upon the shares of the stockholder. If the State cannot require of the bank to pay the tax on the shares of its stock it must be because the Constitution of the United States, or some act of Congress, forbids it. There is certainly no express provision of the Constitution on the subject.
But it is argued that the banks, being instrumentalities of the Federal government, by which some of its important operations are conducted, cannot be subjected to such State legislation. It is certainly true that the Bank of the United States and its capital were held to be exempt from State taxation on the ground here stated, and this principle, laid down in the case of McCulloch v. The State of Maryland, has been repeatedly affirmed by the court. But the doctrine has its foundation in the proposition, that the right of taxation may be so used in such cases as to destroy the instrumentalities by which the government proposes to effect its lawful purposes in the States, and it certainly cannot be maintained that banks or other corporations or instrumentalities of the government are to be wholly withdrawn from the operation of State legislation. The most important agents of the Federal government are its officers, but no one will contend that when a man becomes an officer of the government he *362 ceases to be subject to the laws of the State. The principle we are discussing has its limitation, a limitation growing out of the necessity on which the principle itself is founded. That limitation is, that the agencies of the Federal government are only exempted from State legislation, so far as that legislation may interfere with, or impair their efficiency in performing the functions by which they are designed to serve that government. Any other rule would convert a principle founded alone in the necessity of securing to the government of the United States the means of exercising its legitimate powers, into an unauthorized and unjustifiable invasion of the rights of the States. The salary of a Federal officer may not be taxed; he may be exempted from any personal service which interferes with the discharge of his official duties, because those exemptions are essential to enable him to perform those duties. But he is subject to all the laws of the State which affect his family or social relations, or his property, and he is liable to punishment for crime, though that punishment be imprisonment or death. So of the banks. They are subject to the laws of the State, and are governed in their daily course of business far more by the laws of the State than of the nation. All their contracts are governed and construed by State laws. Their acquisition and transfer of property, their right to collect their debts, and their liability to be sued for debts, are all based on State law. It is only when the State law incapacitates the banks from discharging their duties to the government that it becomes unconstitutional. We do not see the remotest probability of this, in their being required to pay the tax which their stockholders owe to the State for the shares of their capital stock, when the law of the Federal government authorizes the tax.
If the State of Kentucky had a claim against a stockholder of the bank who was a non-resident of the State, it could undoubtedly collect the claim by legal proceeding, in which the bank could be attached or garnisheed, and made to pay the debt out of the means of its shareholder under its control. This is, in effect, what the law of Kentucky does in regard to the tax of the State on the bank shares. It is no *363 greater interference with the functions of the bank than any other legal proceeding to which its business operations may subject it, and it in no manner hinders it from performing all the duties of financial agent of the government.
A very nice criticism of the proviso to the 41st section of the National Bank Act, which permits the States to tax the shares of such bank, is made to us to show that the tax must be collected of the shareholder directly, and that the mode we have been considering is by implication forbidden. But we are of opinion that while Congress intended to limit State taxation to the shares of the bank, as distinguished from its capital, and to provide against a discrimination in taxing such bank shares unfavorable to them, as compared with the shares of other corporations, and with other moneyed capital, it did not intend to prescribe to the States the mode in which the tax should be collected. The mode under consideration is the one which Congress itself has adopted in collecting its tax on dividends, and on the income arising from bonds of corporations. It is the only mode which, certainly and without loss, secures the payment of the tax on all the shares, resident or non-resident; and, as we have already stated, it is the mode which experience has justified in the New England States as the most convenient and proper, in regard to the numerous wealthy corporations of those States. It is not to be readily inferred, therefore, that Congress intended to prohibit this mode of collecting a tax which they expressly permitted the States to levy.
It is said here in argument that the tax is void because it is greater than the tax laid by the State of Kentucky on other moneyed capital in that State. This proposition is not raised among the very distinct and separate grounds of defence set up by the bank in the pleading. Nor is there any reason to suppose that it was ever called to the attention of the Court of Appeals, whose judgment we are reviewing. We have so often of late decided, that when a case is brought before us by writ of error to a State court, we can only consider such alleged errors as are involved in the record, and actually received the consideration of the State court, that *364 it is only necessary to state the proposition now. As the question thus sought to be raised here was not raised in the Court of Appeals of Kentucky, we cannot consider it.
JUDGMENT AFFIRMED.
