delivered the opinion of the court.
This is an action against certain railroads to recover taxes and penalties. The Supremo Court of the State held the penal
*224
ties to be void under the state constitution, but upheld the tax.
The act in question is entitled “An Act imposing a tax upon railroad corporations . . . and other persons . . . owning ... or controlling any line of railroad in this State . . . equal to one per cent, of their gross receipts ... and repealing the existing tax on the gross passenger earnings of railroads.” It proceeds in § 1 to impose upon such railroads “ an annual tax for the year 1905, and for each calendar year thereafter, equal to one per centum of its gross receipts, if such line of railroad lies wholly within the State.” In § 2 a report, under oath, of “the gross receipts of such line of railroad, from every source whatever, for the year ending on the thirtieth day of June last preceding,” and immediate payment of the tax “calculated on the gross receipts so reported,” are required. The comptroller is given power to call for other reports, and is to “ estimate such tax on the true gross receipts thereby disclosed,” etc. Tiie lines of the railroads concerned are wholly within the State, but they connect with other lines, and a part, in some instances much .the larger part, of their gross receipts is derived from the'carriage of passengers and freight coming from, or destined to, points without the State. In view of this portion of their business, the railroads contend that the case is governed by

It being once admitted, as of course it must, be, that not every law that affects commerce among -thé States is a regulation of it in a constitutional sense, nice distinctions are to be expected. Regulation and commerce among the States both are practical rather than technical conceptions, and, naturally, their limits must be fixed by practical lines. As the property of companies engaged in such commerce may be taxed,

Since the commercial value of property consists in the expectation of income from it, and since taxes ultimately, at least in the long run, come out of income, obviously taxes called taxes on property and those called taxes on income or receipts tend to run into each other somewhat as fair value and anticipated profits run into each other in the law of damages. The difficulty of distinguishing them became greater when it was decided, not without much debate and difference of opinion, that interstate carriers’ property might be- taxed as a going concern. In

By whatever name the exaction may be called, if it amounts to no more than the ordinary tax upon property or a just equivalent therefor, ascertained by reference thereto, it is not open to attack as inconsistent with the Constitution.”

v.
Adams,
We are of opinion that the statute levying this tax does amount to an attempt to regulate commerce among the States.' The distinction between a tax “ equal to ” one per cent of gross receipts and a tax of one per cent of the same, seems to us nothing, except where the former phrase is the index of an actual attempt to reach the property and to let the interstate traffic and the receipts from it alone. We find no such attempt or anything to qualify the plain inference from the statute taken by itself. On the contrary, we rather infer from the judgment of the state court and from the argument on behalf of the State *228 that another tax on the property of the railroad is upon a valuation of that property taken as a going concern. This is merely an effort to reach the gross receipts, not even disguised by the name of an occupation tax, and in no way helped by the words “ equal to.”
Of course, it does not matter that the plaintiffs in error are domestic corporations or that the tax embraces indiscriminately gross receipts from commerce within as well as outside of the State. We are of opinion that the judgment should be reversed.
Judgment reversed.
In my opinion the court ought to accept the interpretation which the Supreme Court of Texas places upon the statute in question. In other words, it should be assumed that, by imposing upon railroads and corporations owning, operating, managing or controlling any line of railroad in the State, for the transportation of passengers, freight or baggage, an annual tax “equal to one per centum of its gross receipts if such line of railroad lies wholly within the State, and if such line of railroad lies partly within and partly without the State, it shall pay a tax equal to such proportion of the said one per centum of its gross receipts as the length of the portion of such line within the State bears to the whole length of such .line,” the State intended to impose only an occupation tax. Such is the construction which the state court places on the statute and that construction is justified by the words used. We have the authority of the Supreme Court of Texas for saying that the constitution of that State authorizes the imposition of occupation taxes upon natural persons and upon corporations, other than municipal, doing business in th%t State. The plaintiff in error is a Texas corporation, and it cannot be doubted that the State' may impose an occupation tax on one of its own corporations, *229 provided such tax does not interfere with the exercise of some power belonging to the United States.
But it is said that the tax in question, even if regarded as an occupation tax, is invalid, as constituting a direct burden on interstate commerce, the regulation of which belongs to Congress. It is not, in my opinion, to be taken as a tax on interstate commerce in the sense of the Constitution; for its operation on interstate commerce is only incidental, not direct. A State, in the regulation of its internal affairs, often prescribes rules which in their operation, remotely or incidentally, affect interstate commerce. But such rules have never been held as in themselves imposing direct burdens upon such commerce, and on that ground invalid. The State in the present case ascertains the extent of business done by the corporation in the State, and requires an annual occupation tax “equal” to a named per centum of the amount of such business. It does not lay any tax directly upon the gross receipts as such, as was the case in

v.
Pennsylvania,
If it did not delay an announcement of the court’s decision longer, perhaps, than is desirable, I should be glad to go into this subject at large and present such a review of the adjudged cases as would show 'that the views expressed by me are in harmony with previous cases in this court. The present detf cisión, I fear, will seriously affect the taxing laws of many States, and so impair the powers of the several States, in matters of taxation, that they cannot compel its own corporations to bear their just proportion of such public burdens as can be met only by taxation. I dissent-jfrom the opinion and judgment of the court.
