OPINION OF THE COURT

Real property which is owned by a not-for-profit corporation and used exclusively to provide housing for staff personnel of a separate hospital corporation is1 "conducted” exclusively for hospital purposes and is, therefore, exempt from taxation under section 421 (subd 1, par [a]) of the Real Property Tax Law, where the property owning corporation operates solely to carry out a purpose of the exempt corporation. The order of the Appellate Division affirming the judgment of the Supreme Court declaring the property exempt and directing a refund of taxes paid by petitioner should be affirmed, with costs.

On this appeal from the Appellate Division order, here by our leave, the affirmed findings of fact establish that petitioner, St. Joseph’s Health Center Properties, Inc. ("Properties”), is a ngt-for-profit corporation the purposes of which, as stated in its* certificate of incorporation and by-laws, include *130"To receive and pay over monies to St. Joseph’s Hospital Health Center1 for its corporate purposes” and "to carry out such programs, research or activities as may be necessary or desirable to further the corporate interests of St. Joseph’s Hospital Health Center” and limit Properties’ purposes "to those which are strictly scientific, educational and charitable as more specifically described above” (emphasis supplied). Paragraph 7 of the certificate also requires that there be not less than three nor more than nine directors "all of whom shall be members of the Board of Trustees of St. Joseph’s Hospital Health Center and they shall be designated at the Annual Meeting by the President of St. Joseph’s Hospital Health Center.”2 Equity Term also found that: the properties in question in these proceedings are adjacent to the Hospital and its school of nursing; they are used exclusively to house Hospital personnel, which makes it possible to attract desirable personnel from outside the area; the rents are nominal; the properties are managed by Hospital’s director of special services and security and are maintained by Hospital to which the rents are turned over and which pays for all utilities and maintenance of the properties.

The city argues that Properties does not satisfy the exclusive purposes requirement of section 421 (subd 1, par [a]) of the Real Property Tax Law, that to be exempt the properties must be owned by Hospital rather than an alter ego and that to hold otherwise is inconsistent with the legislative purpose to stem erosion of municipal tax bases. As hereafter demonstrated these arguments ignore both judicial precedent and the addition to the subdivision in question by chapter 414 of the Laws of 1971 of the words "or conducted” after the word "organized”, which amendment makes clear the legislative purpose to grant tax exemption to a corporate property owner conducted for a hospital purpose, even though the owner corporation is not itself authorized to operate a hospital.

The city’s argument concedes that if Hospital itself owned *131the properties in question they would be within the. exemption granted by the Legislature and thus by legislative design unavailable as a part of the municipal tax base. The concession is not surprising in view of our decision in Matter of St. Luke’s Hosp. v Boyland (12 NY2d 135). In St. Luke’s we held exempt apartment buildings owned by a hospital corporation, located in close proximity to the hospital, to the extent used as living accommodations for hospital personnel and their immediate families, reasoning that such use was " 'reasonably incident’ to the major purpose of the hospital” (12 NY2d, at p 143) and that neither the fact that the buildings were not immediately contiguous to the hospital nor that rent was paid by the hospital personnel occupying the apartments destroyed the exemption. Not only was that holding amply supported by prior precedents of our and other courts cited at pages 143 and 144 of the St. Luke’s decision, but it has been followed consistently since in Matter of Genesee Hosp. v Wagner (47 AD2d 37, affd on opn below 39 NY2d 863); Matter of Shrine of Our Lady of Martyrs at Auriesville v Board of Assessors of Town of Glen (40 AD2d 75, affd 33 NY2d 713); Matter of Chautauqua Inst. v Town of Chautauqua (35 AD2d 1, mot for lv to app den 27 NY2d 485); see Matter of Faculty-Student Assn. of State Univ. Coll. at Oswego v Sharkey (35 AD2d 161, affd 29 NY2d 621).

The city’s alter ego contention is answered by the last cited case as well as by Matter of Beth Israel Hosp. Housing Co. (Catherwood) (35 AD2d 397). Matter of Faculty-Student Assn. (supra) involved two nonprofit corporations, one organized to promote educational relations at a college of the State University and which under contract with the State University operated food services, a book and supply store and other activities at the college; the other organized to promote fellowship among students at the same college and which operated off-campus properties for recreation and housing of students and faculty members of the college. The same section of the Real Property Tax Law (then numbered § 420) was involved, but since the proceedings arose before 1971 its then wording required that to be exempt, property be "owned by a corporation or association organized exclusively for” educational purposes, among others. The conclusion was that the corporations were "organized exclusively” for educational purposes since their functions were "necessary to the college community and so further the goal of education” (35 AD2d, at p 166). Beth *132Israel (supra) concerned a membership corporation organized under the Private Housing Finance Law for the purpose of building and operating housing facilities for hospital personnel and their families. The Appellate Division, Third Department, noting that occupancy of the housing company’s properties was limited to hospital personnel, that the company’s directors were required to be directors or trustees of the hospital, and that on dissolution its property reverted to the hospital, held the company to be "merely an appendage of the hospital” and therefore "operated exclusively for hospital purposes”3 within the meaning of the requirement of subdivision 4 of section 560 of the Labor Law, as it then read, that the corporation be "organized and operated exclusively for * * * charitable purpose”.

If any question remained after the Faculty-Student and Beth Israel decisions about the right to exemption of a corporation which performed a function "reasonably incident to the major purpose of’ a separate exempt corporation (People ex rel. Watchtower Bible & Tract Soc. v Haring, 8 NY2d 350, 358; accord Matter of St. Luke’s Hosp. v Boyland, 12 NY2d 135, supra), it was removed by the enactment of chapter 414 of the Laws of 1971. Adopted after intensive study by the Joint Legislative Committee to Study and Investigate Real Property Tax Exemptions culminating in a report (NY Legis Doc, 1970, No. 15) which pointed up the need of municipalities for a broader tax base and which, therefore, inserted a new subdivision (b) making the exemptions enumerated therein subject to local option rather than absolute, as they previously had been, it nevertheless inserted in both subdivision (a), which continued the State mandated exemption of hospitals, among others, and in the new subdivision (b), which established "local option” exemptions, the words "or conducted” between "organized” and "exclusively”. Such legislative history as there is concerns the reasons for the local option provision and does not discuss the reason for the insertion of the words "or conducted.”4 The facts that the insertion is in *133the disjunctive, that it was made at a time when municipalities were being granted relief the need for which was well documented, that it was made in both subdivisions, and that it was made but shortly after the Faculty-Student and Beth Israel5 decisions, strongly suggest however, the Legislature’s intention to exempt property owned by a corporation conducted for a purpose reasonably incident to the major purpose of another subdivision (a) exempt corporation, even though not itself organized to engage in all of the activities of the latter corporation.

There is yet another argument by analogy supporting the conclusion reached. Subdivision 2 of section 421 provides that such portion of real property as is used for exempt purposes is exempt even though some part of the property is used for nonexempt purposes. That declaration is, however, followed by a proviso that "such real property [i.e., that specified in paragraphs (a) and (b) of subdivision 1] shall be fully exempt from taxation although it or a portion thereof is used * * * for purposes which are exempt pursuant to this section * * * by another corporation which owns real property exempt from taxation * * * or whose real property if it owned any would be exempt from taxation”. That provision derives from an amendment adopted in 1948 in order to overturn cases such as People ex rel. Frick Collection v Chambers (196 Misc 1026, affd 276 App Div 891), which had held that an exempt corporation which allowed its property to be used by another exempt corporation thereby lost its exemption (NY Legis Ann, 1948, pp 291-293). Having thus made clear that ownership and use by separate exempt corporations did not forfeit the exemption, the Legislature can hardly be deemed to have intended in the circumstances of the present case that exemption be denied notwithstanding a clearly exempt use simply because the user though empowered to carry out a function which is part of an exempt purpose is not itself empowered to carry out all of the functions of the exempt purpose. The more so is that true after the addition in 1971 of the words "or conducted” to paragraph (a) of subdivision 1.

In conclusion it is necessary only to note that nothing in Mohonk Trust v Board of Assessors of Town of Gardiner (47 *134NY2d 476), Matter of Presbyterian Residence Center Corp. v Wagner (66 AD2d 998, affd 48 NY2d 885), or Matter of St. Joseph’s Health Center Props. v State Tax Comm. (55 AD2d 484, mot for lv to app den 41 NY2d 804) is contrary to the conclusion here reached,6 and that to the extent that Matter of Columbia County Mental Retardation Realty Co. v Palen (97 Misc 2d 9) is to the contrary7 we do not adopt its reasoning.

For the foregoing reasons the order of the Appellate Division should be affirmed, with costs.

(dissenting). The majority today holds that a corporation organized and conducted solely to aid an *135exempt corporation is itself entitled to an exemption under the Real Property Tax Law. Because this action contravenes the well-recognized concerns of the Legislature and the language of the statute itself, I must dissent.

Petitioner, a Type B not-for-profit corporation set up by St. Joseph’s Hospital Health Center in 1972, seeks an exemption under section 421 (subd 1, par [a]) of the Real Property Tax Law. The corporation owns properties in the Syracuse area, which it rents at low cost to personnel associated with the Hospital. There is no question that the petitioner operates solely for the benefit of the Hospital and is under the effective control of the Hospital. The president of the Hospital selects the corporation’s directors and the Hospital pays the corporation’s maintenance and utility costs and receives any excess revenues. Petitioner argues that because its corporate purposes aid the Hospital, which is undeniably entitled to an exemption under section 421, it also should receive such an exemption. In light of the clear legislative direction to the contrary, however, this court should not read such a "piggyback” exemption into the statute.

Under section 421 (subd 1, par [a]), a corporation seeking an exemption must show that it is "organized or conducted exclusively for religious, charitable, hospital, educational, moral or mental improvement of men, women or children or cemetery purposes * * * and used exclusively for carrying out thereupon one or more of such purposes”.

Petitioner corporation does not assert that it could fulfill the purposes of a hospital itself. The issue is rather whether the corporation, created to assist the Hospital in performing its purposes, can itself be construed as "conducted exclusively for * * * hospital * * * purposes”. The words "or conducted” were added to section 421 (subd 1, par [a]) in 1971, at the same time that the Legislature cut back on the categories of unconditional exemptions under the section and gave municipalities broad power to eliminate other categories of such exemptions. In Mohonk Trust v Board of Assessors of Town of Gardiner (47 NY2d 476), this court analyzed the impact of this addition. It noted (at pp 483-484) that "until 1971 an organization qualified for an exemption only if it was 'organized’ for an exempt purpose (see L 1971, ch 414, § 2). Under that statutory language the determination of an organization’s purpose was in large part limited to an examination of the documents by which it was created and which regulated its organizational *136structure and powers (see Matter of De Peyster, 210 NY 216). Hence, it was irrelevant that a particular organization created under a broad charter or agreement providing both exempt and nonexempt purposes might in fact have limited its activities solely to exempt purposes. Now, however, an organization may be entitled to an exemption if it is either 'organized or conducted’ primarily for an exempt purpose or purposes. Hence, the determination of an organization’s primary purpose may turn upon the extent to which it pursues the-various purposes for which it was created, and is not necessarily dependent solely upon the language of the document pursuant to which the organization operates” (emphasis in original).

A wide variety of corporate purposes qualified for exemptions before the Legislature cut them back in 1971. By simultaneously adding the words "or conducted”, as Mohonk Trust noted, the Legislature permitted examination of which stated purposes a corporation was actually implementing where the certificate of incorporation or by-laws included both exempt and nonexempt purposes. Both before and after the 1971 amendments, however, the statute distinguished this inquiry from the separate and additional requirement that the property be actually used for a tax exempt purpose. This court has long recognized the dual nature of this test, that "[bjefore nonprofit real property may be exempt from taxes, petitioner must establish that it is (1) organized or conducted exclusively for one or more exempt purposes specified in the statute and (2) used exclusively for such exempt purposes (Matter of Association of Bar of City of N. Y. v Lewisohn, 34 NY2d 143; Matter of Genesee Hosp. v Wagner, 47 AD2d 37, 43, affd 39 NY2d 863)” (Matter of Presbyterian Residence Center Corp. v Wagner, 66 AD2d 998, 999, affd 48 NY2d 885). The majority today overlooks the requirement that the corporation be organized or conducted for an exempt purpose and instead focuses solely on the requirement that the corporation’s property be used for an exempt purpose. It applies only half of the statute’s test for exempt status.

When the full two-part test of section 421 (subd 1, par [a]) is applied to this case, it is clear that petitioner is not entitled to an exemption. The purposes for which it was organized or conducted, either those stated in its corporate papers or those stated purposes that it has actually implemented, are not those of a hospital. Petitioner could not legally operate or conduct a hospital. Petitioner thus fails this portion of the *137test, regardless of whether its property is actually used to further the purposes of a hospital corporation.

Petitioner cannot dispute that it was organized primarily and is conducted solely for the purpose of owning, operating and managing real property. Unable to meet the statute’s requirements, it would have this court usurp the Legislature’s function and amend the section to permit it to ride on the exempt shoulders of the Hospital. If the Hospital itself owned the properties in question there would of course be no doubt as to their exempt status (Matter of St. Luke’s Hosp. v Boyland, 12 NY2d 135).* But the properties are owned by a separate corporation, and section 421 (subd 1, par [a]) requires that either the purposes for which such corporation is organized or those stated purposes to which it actually gives effect must fall into one of the exempt categories in paragraph (a). Aiding another corporation that does qualify for the exemption is not one of the purposes listed in paragraph (a), and this court would do violence to the statute if it were to read it into the section.

As this court has already asserted, the prime purpose behind the 1971 amendments was to stem the steadily increasing flow of property from municipal tax rolls (e.g., Association of Bar, supra, at p 155; Matter of American Bible Soc. v Lewisohn, 40 NY2d 78, 86). The joint legislative committee whose recommendations formed the basis for the amendments estimated that more than 30% of the real property in the State was tax exempt and that unless action was taken that figure would rise to 50% by 1985 (NY Legis Doc, 1970, No. 15). The Legislature then acted to give municipalities greater leeway to cut back on such exemptions. This is not to argue that the motives for which petitioner corporation was created are in any way unworthy. The Legislature might very well decide in the future that a corporation one step removed from the exempt purposes of the statute should be allowed an *138exemption. But in light of the Legislature’s concern over the impact of exemptions on municipal tax rolls, as well as the traditional maxim that exemption statutes should be construed strictly against the party seeking the exemption, this court should not take it upon itself to make such a policy determination.

It remains to distinguish two Appellate Division opinions relied upon by petitioner, Matter of Faculty-Student Assn. of State Univ. Coll. at Oswego v Sharkey (35 AD2d 161, affd 29 NY2d 621) and Matter of Beth Israel Hosp. Housing Co. (Catherwood) (35 AD2d 397). In each case, the Appellate Division countenanced exemptions in situations similar in many respects to the case at hand. This court, however, has never expressly adopted the reasoning of these decisions. The court never passed on Beth Israel, and it affirmed Faculty-Student Association, without opinion. Significantly, the cases were decided by the Appellate Division in 1970, before the Legislature reversed a trend of many years and moved to curtail the expansion of real property tax exemptions. In light of the detailed discussion that this court has subsequently given to the Legislature’s motivation in enacting the 1971 amendments, these cases are of questionable applicability to the current situation. They certainly do not provide a strong enough base to allow this court to rewrite the Legislature’s handiwork in such a sensitive area.

From time immemorial, real property tax exemption statutes have been construed rigidly against parties claiming exemptions. Exemptions have been denied unless the statutory language was clear and unambiguous and unless the intention of the Legislature to grant the exemption indisputably appeared. Any doubt should be resolved in favor of the taxing authority. (See Town of Harrison v County of Westchester, 34 Misc 2d 1020, 1033 [Hoyt, J.], affd 18 AD2d 1136, affd 13 NY2d 258.)

Property tax exemptions have the direct effect of shifting the burden of who must pay for municipal services. Simple arithmetic dictates that when one parcel is removed from the tax rolls, all other taxpayers — businesses, nonexempt nonprofit organizations, homeowners — must pay an increased share. The Legislature was aware of this in 1971 when, in the same act that amended the statute involved here, it declared that "the continuous removal from the tax rolls of taxable real property, is a particular hardship on the local govern*139ments of this state and upon the citizens of this state” (L 1971, ch 414, § 1). Certainly there are many organizations that should receive exemptions. The fact that the Legislature has granted the exemptions that it has testifies to this. But in these days when municipalities are already hard pressed and requests for tax exemptions are mushrooming, this court should not take it upon itself to alter the scheme established by the Legislature.

The order of the Appellate Division should be reversed.

Order affirmed.
