delivered the opinion of the court.
This action was brought by the Underwood Typewriter Company, a Delaware corporation, in the Superior Court for the County of Hartford, Connecticut, to recover the amount of a tax assessed upon it by the latter State and paid under protest. The company contended that as applied to it the taxing act violated rights guaranteed by the Federal Constitution. The constitutional questions involved were reserved by that court for consideration and advice by the Supreme Court of Errors. The answers to these questions being favorable to the State, 94 Connecticut, 47, judgment was entered by the Superior Court confirming the validity of the tax. The case comes here on writ of error to that court.
Connecticut established in 1915 a comprehensive system of taxation applicable alike to all foreign and domestie corporations carrying on business within the State. This system prescribes practically the only method by which such corporations are taxed, other than the general property tax to which all property located within the State, whether the owner be a resident or a nonresident, an individual or corporation, is subject. The act divides business corporations into four classes and the several classes are taxed by somewhat different methods. The fourth class, “Miscellaneous Corporations,” includes, among others, manufacturing and trading companies, and with these alone are we concerned here. Upon their net income earned during the preceding year from business carried on within the State a tax of two per cent, is imposed annually. The amount of the net income is ascertained by reference to the income upon which the corpora^ *118 tion is required to pay a tax to the United States. If the company carries on business also outside the State of Connecticut, the proportion of its net income earned from business carried on within the State is asc'ertainéd by apportionment in the following manner: The corporation is required to state in its annual return to the tax commissioner from what general source its profits are principally derived. If the company’s net profits are derived principally from ownership, sale or rental of real property, or from the sale or use of tangible personal property, the tax is imposed on such proportion of the whole net income, as the fair cash value of the real and the tangible personal property within the State bears to the fair cash value of all the real and tangible personal property of the company. If the net profits of the company are derived principally from intangible property the tax is imposed upon such proportion of the whole net income as the gross receipts within the State bear to the total gross receipts of the company. A corporation aggrieved because of a tax assessed upon it may after paying the tax apply for relief to the Superior Court for the County of Hartford. There it may show cause why it is not subject to the tax or why the tax should have been less. If the whole tax assessed is found-by the court to be proper, it enters judgment confirming the same. If the tax is found to be for any reason unauthorized in whole or in part, the court enters judgment for the company in the amount with interest' which it is entitled to recover; and the state treasurer is directed to pay the same. The decision of the superior court is subject to review by the Supreme Court of Errors as in other cases. Laws of 1915, c. 292, part IV, §§ 19-29; Underwood Typewriter Co. v. Chamberlain, 92 Connecticut, 199.
The Underwood Typewriter Company is engaged in the business of manufacturing typewriters and kindred articles; in selling its product and also certain accessories and supplies which it purchases; and in repairing and *119 renting such machines. Its main office is in New York City. All its manufacturing is done in Connecticut. It has branch offices in other States for the sale, lease and repair of machines and .the sale of supplies; and it has one such branch office in Connecticut. All articles made by it — and some which it purchases — are stored in Connecticut until shipped direct to the branch offices, purchasers or lessees. In its return to the tax commissioner of Connecticut, made in 1916 under the abqve law, the company declared that its net profits during the preceding year had been derived principally from tangible personal property; that these profits amounted to $1,336,586.13; that the fair cash value of the real estate and tangible personal property in Connecticut was $2,977,827.67, and the fair cash value of the real estate and tangible personal property outside that State was $3,343,155.11. The proportion of the real estate and tangible personal property within the State was thus 47 per cent. The tax commissioner apportioned that percentage of the net profits, namely $629,668.50, as having been earned from the business done within the State, and assessed thereon a tax of $12,593.37, being at the rate of two per cent. The company having paid the tax under protest, brought this action in the Superior Court for the County of Hartford to recover the whole amount.
First.
It is contended that the tax burdens interstate commerce and hence is void under § 8 of Article I of the Federal Constitution. Payment of the tax is not made a condition precedent to the right of the corporation to carry on business, including interstate business. * Its enforcement is left to the ordinary means of collecting taxes.

Second,.
It is contended that the tax violates the Fourteenth Amendment because, directly or indirectly, it is imposed on income arising from business conducted beyond the boundaries of the State. In considering this objection we may lay on one side the question whether this is an excise tax purporting to be measured by the income accruing from business within the State or a direct tax upon that income; for the “argument, upon analysis, resolves itself into a mere question of definitions, and has no legitimate bearing upon any question raised under the Federal Constitution.”

We have no occasion to consider whether the rule prescribed if applied under different conditions might be obnoxious to the Constitution.

Third.
It is stated in the brief, doubtless inadvertently, that the assignment of errors includes the objection that the tax was void under the' Fourteenth Amendment also on the ground that the company, a foreign corporation, had made large- permanent investments in Connecticut before the statute of 1915 was enacted. No such error appears to have been specifically assigned and the objection was not pressed in brief or oral argument. It is clearly unsound. To the facts presented here the principle discussed in
