delivered the opinion of the court.
The judgment brought up by this writ of error was entered by the Circuit Court of Milwaukee County upon the mandate of the Supreme Court of the State of Wisconsin issued on reversal of a previous judgment of the circuit court in an action brought by plaintiff in error to recover the sum of $2,835.38, paid under protest as part of a tax assessed and levied by the taxing authorities of the State upon plaintiff’s income for the year 1911, under c. 658, Wisconsin Laws 1911. The Supreme Court overruled plaintiff’s contention that the portion of the tax that was in controversy, having teen imposed upon income derived by plaintiff from interstate./commerce, amounted to a burden upon that commerce, contravening the commerce clause of § 8 of Article 1 of the Constitution of the United States. 161 Wisconsin, 211. -And this is the sole question presented for our consideration.
.The act, which was passed under the authority of an amendment to the state constitution (Income Tax Cases, 148 Wisconsin, 456), imposes a tax upon incomes received during the year ending December 31, 1911, and annually thereafter; defines the term “income” as including (a) rent of real estate; (b) interest derived from money loaned or invested in notes, mortgages, bonds, or other evidences of debt; (c) wages,-salaries, and the like; (d) dividends or profits derived from stoek, or from the purchase and sale of property acquired within three years previous, or from any business whatever; (e) royalties derived from the possession or use of franchises or legalized privileges; and (f) all other income derived from any source, except such as is exempted. There is a provision, “That any person engaged in business within and without the state shall, with respect to income other than that derived from rentals, stocks, bonds, securities or evidences of indebtedness, be taxed only upon that proportion of such income as is. *324 derived from business transacted and property, located within the state,” which is to be determined in a particular manner specified in § 1770b, ás far as applicable..
Corporations are allowed to make certain deductions from gross income, including amounts paid for personal services of officers and employees and other ordinary expenses paid out of income in the maintenance and operation of business and property, including a reasonable allowance for depreciation, losses not compensated for by insurance or otherwise, taxes, etc. These need not be further mentioned, beyond saying that the intent and necessary effect of the act is to tax not gross receipts but net income; that from the stipulated facts it appears that the tax in question was imposed upon plaintiff’s net income; and that this is in accord wifh the construction of the act adopted by the supreme coutf't of the State in this and other cases. State ex rel. Manitowoc Gas Co. v. Wisconsin Tax Commission, 161 Wisconsin, 111, 116; United States Glue Co. v. Oak Creek (the present case), 161 Wisconsin, 211, 221; State ex rel. Bundy v. Nygaard, 163 Wisconsin, 307, 310.
In order to determine what part of the income of a corporation engaged in business within and without the State (other than that derived from rentals, stocks, bonds,' securities, etc.) is to be taxed as derived from business transacted and property located within the State, reference is had to. a formula prescribed by another statute [§ 1770b, subsec. 7, par. (e) of Wisconsin Stats.] for apportioning the capital stock of foreign corporations, under which the gross business in dollars of the corporation in the State, added to the value in dollars of its property in the State, is made the numerator of a fraction of which the denominator consists of the total gross business in dollars of the corporation both within and without the State, added, to the value in dollars of its property within and without the State. The resulting fraction is taken by the income tax law as representing the *325 proportion of the income which is deemed to be derived from business transacted and property located within the State. This formula was applied in apportioning plaintiff’s net “business income” for the year 1911, and upon the portion thus attributed to the State, plus the income from rentals, stocks, bonds, etc., the tax in question was levied.
Plaintiff was and is a corporation organized under the laws of the State of Wisconsin, having its principal office and place of business in the Town of Oak Creek, where it conducted an extensive manufacturing plant, selling its products throughout the State and in other States and foreign countries. Its net “business income” in the year 1911, exclusive of that derived from rentals, stocks, bonds, etc., and after making the deductions allowed by 'the act, amounted to about $124,000, derived from the, following sources: (a) about $16,000 from goods sold to^customers ■ within the State and delivered from its factory; (b) about $65,000 from goods sold to customers outside of the State and delivered from its factory; (c) about 331,000 fr©m goods sold to customers outside of the State,‘the sales having been made and goods shipped from plaintiff’s branches in other States, and the goods having been manufactured at plaintiff’s factory and shipped before sale to said branches; (d) about $7,000 from goods sold to customers ‘outside of the State, the sales having been made and goods shipped from plaintiff’s branches without the State, these goods having been purchased by plaintiff outside of the State and shipped to plaintiff’s factory in the State, and thence shipped before sale from the factory to the branches; (e) about $5,000 from goods sold outside of the State, the sales having been made and goods shipped from said branches, and the goods having been purchased by plaintiff outside of the State and shipped from the points of purchase to the branches without coming into the State of Wisconsin.
*326 No contention was made as b'o the taxability of the income designated in item (a). Plaintiff’s contention ¡that items (d) and (e) were not taxable because not derived from property located or business transacted within ‘the State was upheld by the state courts. Thus the controversy is narrowed to the contention, overruled by the supréme court, 'that items (b) and (c) were not taxable because derived from interstate commerce.
Stated concisely, the question is whether a State, in levying a general income tax upon the gains and profits of a domestic corporation, may include in the computation the net income derived from transactions in interstate commerce without contravening the commerce clause of the Constitution of the United States.
It is settled that a State may not directly burden interstate commerce, either by taxation or otherwise. Bub a tax that only indirectly affects the profits or returns from such commerce is not within the rule. Thus, it was declared in
Postal Telegraph Cable Co.
v.
Adams,
Yet it is obvious that taxes imposed upon property or franchises employed in interstate commerce must be paid from the net returns of such commerce, and diminish them in the same sense that they are diminished by a tax imposed upon the net returns themselves.
The distinction between direct and indirect burdens, with particular reference to a comparison between a tax upon the gross returns 6f carriers in interstate commerce and a general income tax imposed upon all inhabitants incidentally affecting carriers engaged in such commerce, was the subject of consideration in
Philadelphia & Southern S. S. Co.
v.
Pennsylvania,
The correct line of distinction is so well illustrated in two cases decided at the) present term that we hardly need go further. In
Crew Levick Co.
v.
Pennsylvania,
The difference in effect between a tax measured by gross receipts and one measured by net income, recognized by our decisions, is manifest and substantial, and it affords a convenient and workable basis of distinction between a direct and immediate burden upon the business affected and a charge that is only indirect and inci *329 dental. A tax upon gross receipts affects each transaction in proportion to its magnitude and irrespective of . whether it is profitable or otherwise. Conceivably it may be sufficient to make the difference between profit and loss, or to so diminish the'profit as to impede or discourage the conduct of the commerce. A tax upon the net profits has not the same deterrent effect, since it does not arise at all unless a gain is shown over and above expenses and losses, and the tax cannot be heavy -unless the profits áre large. Such a tax, when imposed upon net incomes from whatever source arising, is but a method of distributing the cost of government, like a tax upon property, or upon franchises treated, as property; and if there be no discrimination against interstate commerce, either in the admeasurement- of the tax or in the means adopted for enforcing it, it constitutes one of the ordinary and general burdens of government, from which persons and corporations otherwise subject to the jurisdiction of the States are not exempted by the Federal Constitution because they happen to be engaged ha commerce among the States.
And so we hold that the Wisconsin income tax law, as applied to the plaintiff in the case before us, can not be deemed to be so direct a burden upon plaintiff’s interstate business as to amount to an unconstitutional interference with or regulation of coaaomerce. among the States. It. was measured not by the gross receipts, but by the'net proceeds from this part of plaintiff’s business, along with a like imposition upon its income derived from other sources, and in the same way that other corporations doing business within the State aré taxed upon that proportion of their income derived from business transacted and property located within the State, whatever the nature of their business.
Judgment affirmed
