TAX REVIEW BOARD OF PHILADELPHIA, Appellant,
v.
HEINTZ INVESTMENT CO.
Supreme Court of Pennsylvania.
Argued January 14, 1975.
Decided April 17, 1975.
*250 Martin Weinberg, City Sol., Leonard B. Rosenthal, James M. Penny, Jr., Asst. City Solicitors, Stewart M. Weintraub, Philadelphia, for appellant.
Park B. Dilks, Jr., Morgan, Lewis & Bockius, Philadelphia, for appellee.
Before JONES, C.J., and EAGEN, O'BRIEN, ROBERTS, POMEROY and MANDERINO, JJ.

OPINION OF THE COURT
O'BRIEN, Justice.
This appeal arises from an order of the Commonwealth Court which reversed the order of the Court of Common Pleas of Philadelphia. We granted allocatur.
The narrow issue presented in this appeal is whether appellee, Heintz Investment Company, is "engaged in business" within the meaning of § 19-1001 et seq., of the *251 Code of General Ordinances of the City of Philadelphia. In the Code, "business" is defined as follows:
"The carrying on or exercising for gain or profit within the City any trade, business, profession, vocation, or making sales to persons within the City, or any manufacturing, commercial or financial activity, service or business, including but not limited to manufacturers, brokers, wholesale dealers or wholesale vendors, retail dealers or retail vendors."
Prior to 1957, appellee was engaged in the manufacturing business in Philadelphia, under the name "Heintz Manufacturing Company," and paid the proper gross-volume tax. In September of 1957, appellee sold its inventory and certain other assets, receiving cash and certain shares in the company which purchased the assets. Pursuant to the sales agreement of 1957, appellee leased its plant and plant site to a purchaser for a ten-year period with an option to renew for five years as well as an option to buy the plant. All expenses surrounding the leased building were paid by the lessee and appellee-lessor provided no services to lessee. The option to purchase provided for in the lease was exercised by lessee in September of 1967. Appellee thereafter changed its corporate name to Heintz Investment Company.
Subsequent to the 1957 sale of inventory, appellee, rather than distributing the proceeds to stockholders, held the capital and invested it and distributed the income from varied investments and the profits on the rental property. In 1958, appellee amended its corporate charter to allow the corporation "to invest in, own, hold, use, develop, improve, manage, operate, control real and personal property of any nature whatsoever, as principal only not as agent or broker. . . ." Also in 1958, appellee asked for and received an opinion from the Department of Collections of Philadelphia that under the circumstances, it would not be subject to the mercantile tax.
*252 In August of 1968, appellee received a delinquent mercantile tax bill for the years 1958-1968. After a hearing, the Tax Review Board of Philadelphia, appellant herein, denied appellee's request for relief. Appellee then appealed to the Court of Common Pleas of Philadelphia, which affirmed the board. The Commonwealth Court reversed the board and the Court of Common Pleas, and appellant sought allocatur, which we granted.
Appellant, relying on our decision in Tax Review Bd. v. Brine Corp., 414 Pa. 488, 200 A.2d 883 (1964), contends that appellee was in fact engaged in business within the meaning of the ordinance. In Brine, we held that a corporation originally formed for the specific purpose of acquiring parking lot facilities and leasing the facilities to other persons was subject to the Philadelphia Mercantile Tax, even though appellant in Brine, as in the instant case, performed no services whatsoever for the lessee. In finding the corporation receipts taxable in Brine, supra, we stated:
"These differences in how the property was acquired or circumstances under which it is retained, in how it is used, in services performed by way of management, and in the overall objectives of the owner are the differences which lead to tax in one case and not in the other." At page 494, 200 A.2d at 886.
The reasons for which we found appellant taxable in Brine do not exist in the case at bar. In the instant case, appellee-corporation was not originally formed for the purpose of leasing the property it acquired, but rather only leased its property after the cessation of its general manufacturing operations, and leased its real estate as a means to preserve a corporate asset that might be needed in the future. Under these circumstances, we hold that appellant's income from its rental property is not taxable within the meaning of the *253 Philadelphia Code. Cf. A.H. Geuting Co. v. City of Philadelphia, 1 D. & C.2d 341 (1954).
Since appellee's income from its real estate is passive income and, therefore, not taxable within the Philadelphia Code, we must now consider its income from its stock holdings. Appellee, after the cessation of its manufacturing business and the lease of its real estate, engaged heavily in investment in the stock market. Appellee maintained a large portfolio of stocks and paid investment counselors to advise it in the purchase of these stocks. Appellee's voluminous trading in the stock market could hardly be said to be for the preservation of corporate assets, but rather was designed to increase the assets of the corporation and to benefit its shareholders. Under these circumstances its income from its stockholdings must be considered active income and taxable within the meaning of the Philadelphia Code. See Sun Oil Co. v. Tax Review Board, 417 Pa. 443, 207 A.2d 855 (1965).
Order of the Commonwealth Court affirmed in part and reversed in part.
NIX, J., took no part in the consideration or decision of this case.
ROBERTS, J., filed a dissenting opinion in which EAGEN, J., joins.
ROBERTS, Justice (dissenting).
The record plainly reveals that taxpayer was "carrying on . . . for gain or profit within the City [the] business"[*] of investment in real and personal property. Therefore all income derived from that business, including the income derived from its rental property, was subject to the Philadelphia Mercantile License Tax. Cf. Coventry Hills v. Tax Review Board, 437 Pa. 259, 263 A.2d 348 (1970); Kungsgaten, Inc. v. Philadelphia, 422 *254 Pa. 209, 220 A.2d 803 (1966). The reasoning of President Judge Bowman's dissenting opinion to the Commonwealth Court order is most persuasive:
"In my opinion a corporation which has for its sole corporate purpose the production of income or gain from property owned by it is engaged in business within the meaning of the taxing ordinance in question. That it performs and accomplishes its sole purpose for existence through the services of investment counselors, brokers or other independent contractors neither diminishes nor enlarges its involvement. I distinguish A.H. Geuting Company v. City of Philadelphia, 1 Pa.D. & C.2d 341 (1954), as did the Supreme Court in Tax Review v. Brine Corporation, 414 Pa. 488, 200 A.2d 883 (1964), which said that the [taxpayer in A.H. Geuting Company] did nothing but conserve a piece of real estate retained by it after selling its business. Appellee here had a similar experience but then chose to change its corporate charter to an investment purpose and thereafter engaged in that restated purpose. Surely it was not then merely conserving property previously sold nor could it be appropriately described as passive with respect to its corporate purpose. The overall objective of the corporation leads me to conclude that appellee is engaged in business. I would therefore, affirm the lower court."
I would reverse the order of the Commonwealth Court in its entirety and reinstate the order of the court of common pleas.
EAGEN, J., joins in this dissent.
