Opinion by
The Secretary of Revenue appeals from an order awarding a peremptory writ of mandamus against him.
The petitioners for the writ, National Transit Company and National Transit Pump and Machine Company, are corporations of Pennsylvania; National Transit Company owns 101,790 of the 101,800 outstanding voting shares of the National Transit Pump and Machine Company, the remaining 10 shares being held by directors of the National Transit Company for the purposes of qualification. No facts are in dispute. Both corporations are taxable under the Corporate Net Income Tax Act of May 16, 1935, P. L. 208, 72 PS section 3420a et seq. Section 3 of the act provides: “Every corporation shall be subject to, and shall pay for the privilege of doing business in this Commonwealth, a State excise tax at the rate of six per centum per annum upon each dollar of net income of such corporation.
Section 5 provides: “Consolidated reports. — The Department shall, upon application made to it in such form as it shall prescribe, permit any corporation owning or controlling, directly or indirectly, a majority of the voting capital stock of another corporation or of other corporations, subject to the provisions of this act, to make a consolidated report, showing the combined net income.” Considering themselves entitled to make a consolidated return, the plaintiff corporations applied to the Secretary for the necessary forms for their report. *453 The Secretary refused and this proceeding followed. In his return he gives the following reason for his refusal: “17. Further answering the petition for writ of alternative mandamus, defendant avers that these plaintiffs are not entitled to make a consolidated report for the reason that they can not comply with requirements of Section 6 of the ‘Regulations of the Department of Revenue in effect February 25, 1936/ duly prescribed, adopted and promulgated by the Department of Revenue under Section 9 of the Corporate Net Income Tax Act and for the further reason that it is wholly within the discretion of the Department of Revenue as to whether or not it will allow corporations to make consolidated reports.”
Section 6 of the regulations, prescribed by the Department of Revenue under authority thought to be conferred by section 9 of the Act, provides: “Consolidated reports of corporate net income may be made to the Commonwealth of Pennsylvania only by corporations making consolidated reports to the Federal Government [now, common carriers] for income tax purposes, under section 141 of the Revenue Act of 1934, as amended, and the regulations thereunder. However, all the corporations included in the consolidated report to the Federal Government must be subject to the provisions of the Pennsylvania ‘Corporate Net Income Tax Act’, in order to file a consolidated report in this Commonwealth.”
Plaintiffs deny the power of the Secretary to make such a regulation. They contend that section 5 imposes a mandatory duty and not one merely permissive; the Secretary insists that the legislature has given him discretion to determine whether corporations may consolidate their returns. The learned court below held the provision mandatory.
While the word “shall” is generally regarded as imperative, in some contexts it is given a permissive meaning. The intended meaning is determined by what is intended by the statute: see
Noecker v. Woods,
259 Pa.
*454
160, 166,
The Secretary contends that the “base of the tax to which the rate is to be applied is the net income as returned to and ascertained by the Federal Government” and that only such corporations as are permitted by Congress to file consolidated returns may do so under the state statute. This contention he derives, as we understand his argument, from part of the definition of “net income” contained in section 2. This section entitled “Definitions”, as amended Aug. 7, 1936, P. L. 127, provides, inter alia: “ ‘Net income.’ 1. In case the entire business of the corporation is transacted within this Commonwealth, net income for the calendar year or fiscal year as returned to, and ascertained by the Federal Government, subject, however, to any corree *455 fcions thereof, for fraud, evasion, or error as finally ascertained by tbe Federal Government; Provided, That additional deductions shall be allowed from net income on account of any taxes paid to tbe Government of tbe United States; . . .” It is said that, as by tbe Federal Act of June 22, 1936, c. 690, section 141, 49 Stat. 1698, amending the Act of May 10, 1934, c. 277, section 141, 48 Stat. 720, 26 USCA section 141, consolidated returns may be filed by an “affiliated group of corporations” * engaged as common carriers, plaintiff corporations, not being common carriers, are therefore not within tbe class allowed by tbe Act of Congress to file a consolidated return for federal purposes. But a reading of the act shows that tbe word income has a wider meaning than that attributed by tbe Secretary. Section 2 provides that tbe definition of income is not limited to what has already been quoted, if tbe text of tbe act indicates a different meaning. From section 4 of tbe act, we take tbe following: “. . .it shall be tbe duty of every corporation, liable to pay tax under this act . . . to transmit to tbe department, upon a form prescribed, prepared, and furnished by tbe department, a report under oath or affirmation ... of net income taxable under tbe provisions of this act. Such report shall set forth: (a) A true copy of its return to tbe Federal Government of tbe annual net income arising or accru *456 ing in the calendar or fiscal year next preceding, or such part or portions of said return, as the department may designate, (b) If no return was filed with the Federal Government, the report made to the department shall show such information as would have been contained in a return to the Federal Government, had one been made, and (c) Such other information as the department may require.”
The requirement of a copy of the report made to the Federal Government was doubtless for the information of the Secretary in performing his duties: compare
Com. v. Chambersburg Engineering Co.,
The secretary contends that, if the foregoing view be adopted, the act becomes unconstitutional as creating unlawful classification of corporations for purposes of taxation in violation of the uniformity provision of the Constitution, Article IX, sec. 1. The contention is without merit. In reviewing the wisdom of the classification, the court cannot say that the General Assembly acted unreasonably in determining if a domestic corporation owned or controlled another, they might combine their accounts for the purposes of income taxation. The reasonableness of classification is for the legislature in the first instance; unless there is no rational basis for it, the court will not interfere. In
Com. v. Delaware Division Canal Co.,
It need perhaps not be said that settled principles prohibiting the delegation of legislative power (see
Locke’s Appeal,
Judgment affirmed.
