OPINION
The City of Harrisburg and individual taxpayers (the City, collectively) appeal from a Commonwealth Court Order upholding a tax imposed by the School District of the City of Harrisburg (School District) on the privilege of leasing tax exempt realty. Because we hold that the tax unconstitutional *298 ly distinguishes between lessees of tax exempt and nonexempt realty, we reverse.
BACKGROUND
On June 27, 1994, the Board of Directors of the School District passed Resolution 276, entitled “School District Tax on the Privilege of Leasing Tax Exempt Realty,” which imposed a tax of 10% on the rental consideration paid for the privilege of leasing tax exempt realty in the City. 1 The City owns an island in the Susquehanna River known as “City Island,” which is dedicated to park purposes. The island is exempt from real estate taxation. The privilege of leasing property on the island is, therefore, subject to Resolution 276. The thirteen individual taxpayers, parties to this action, own recreation-related businesses operating on City Island that the tax will burden. The School District has never taxed the privilege of leasing private or nonexempt realty in the City.
To contest the validity of the tax, the City filed an Action for Declaratory Judgment and Notice of Appeal in the Court of Common Pleas of Dauphin County (trial court). 2 After the *299 parties filed stipulated facts, the trial court held a hearing. On January 6, 1995, the court issued an Adjudication and Decree Nisi declaring Resolution 276 invalid. The court held that the tax contravenes Section 204 of the General County Assessment Law (GCAL), Act of May 22, 1933, P.L. 853, as amended, 72 P.S. § 5020-204, and the Uniformity Provision of the Pennsylvania Constitution, Article VIII, § 1. Following a denial of the School District’s motions for post-trial relief, the court entered a final order affirming the decree nisi. On appeal, the Commonwealth Court reversed the trial court and upheld the tax. In a dissenting opinion, the Honorable Dan Pellegrini, joined by the Honorable Bernard L. McGinley and the Honorable Rochelle S. Friedman, concluded that the tax unconstitutionally distinguishes between lessees of tax exempt and nonexempt property.
We granted allocatur to determine whether Resolution 276 violates (1) Section 204 of the GCAL, or (2) the Uniformity Provision of our Pennsylvania Constitution and the Equal Protection Clause of the Fourteenth Amendment to the United States Constitution.
GENERAL COUNTY ASSESSMENT LAW
With certain exceptions not applicable here, the legislature has granted local taxing authorities, such as the School District, broad taxing power pursuant to Section 2 of the Local Tax Enabling Act (LTEA), Act of December 31, 1965, P.L. 1257, as amended, 53 P.S. § 6902. Pursuant to that section, local taxing authorities may:
*300 in their discretion, by ordinance or resolution, for general revenue purposes, levy, assess and collect or provide for the levying, assessment and collection of such taxes as they shall determine on persons, transactions, occupations, privileges, subjects and personal property within the limits of such political subdivisions----
53 P.S. § 6902. Therefore, the School District may, in its discretion, impose taxes for general revenue purposes pursuant to the LTEA.
See F.J. Busse Co. v. City of Pittsburgh,
All other public property used for public purposes, with the ground thereto annexed and necessary for the occupancy and enjoyment of the same, but this shall not be construed to include property otherwise taxable which is owned or held by an agency of the Government of the United States nor shall this act or any other act be construed to exempt from taxation any privilege, act or transaction conducted upon public property by persons or entities which would be taxable if conducted upon nonpublic property regardless of the purpose or purposes for which such activity occurs, even if conducted as an agent for or lessee of any public authority.
72 P.S. § 5020-204(a)(7) (emphasis added).

By its express terms, the Section 204 exemption for public property does not include any activities conducted on public property “which would be taxable” if conducted on nonpublic property.

273,
The rules of statutory construction require us to strictly construe statutes exempting persons or property from taxation. 1 Pa.C.S. § 1928(b)(5);
Lehigh Valley Cooperative Farmers v. Bureau of Security Employment, Department of Labor and Industry,
Resolution of this issue turns on whether “taxable,” as used in Section 204, means “actually taxed” or “capable of being taxed” on nonpublic property. We find no case law that controls our decision in this matter.
Township of South Park,
cited by the City, is not instructive on this issue. There, the township enacted an ordinance that taxed patrons engaging in amusements within its borders. The tax applied to the patrons of the county’s two golf courses, which were located on public property. The issue on appeal was whether the golf courses were exempt from the amusement tax because of their location on public property. Relying on
Weatherly Area School District v. Whitewater Challengers, Inc.,
*302 Because the statute and case law do not define the term “taxable,” as used in Section 204, we construe the term according to its common and approved usage pursuant to the rules of statutory construction. 1 Pa.C.S. § 1903(a). “Taxable,” as defined in Black’s Law Dictionary, means “subject to taxation; liable to be assessed, along with others, for a share in a tax.” Black’s Law Dictionary 1459 (6th ed.1990). Consistent with the dictionary definition, the Commonwealth Court, here, held that “taxable” on nonpublic property does not imply that there must be an actual tax on leases of nonpublic property. We agree with the Commonwealth Court’s interpretation of the term, which properly embodies a strict construction of the Section 204 tax exemption. Lehigh Valley.
The LTEA and the GCAL, thus, empower the School District to tax the privilege of leasing public property to raise revenue for general purposes, even in the absence of a tax on the identical privilege on private or nonexempt property. Our inquiry, however, does not end here. Because the School District does not actually tax the privilege of leasing nonpublic property, we must determine whether the disparate tax treatment accorded lessees of public and nonpublic property violates the constitutional guarantees of uniformity of treatment and equal protection.
UNIFORMITY
The Uniformity Clause of the Pennsylvania Constitution provides:
All taxes shall be uniform, upon the same class of subjects, within the territorial limits of the authority levying the tax, and shall be levied and collected under general laws.
Pa. Const. Art. VIII, § 1. The principles governing the validity of tax classifications are well-established.
Leonard v. Thornburgh,
*303 [u]nder the equal protection clause, and under the Uniformity Clause, absolute equality and perfect uniformity in taxation are not required. In cases where the validity of a classification for tax purposes is challenged, the test is whether the classification is based upon some legitimate distinction between the classes that provides a non-arbitrary and “reasonable and just” basis for the difference in treatment. Stated alternatively, the focus of judicial review is upon whether there can be discerned “some concrete justification” for treating the relevant group of taxpayers as members of distinguishable classes subject to different tax burdens. When there exists no legitimate distinction between the classes, and, thus, the tax scheme imposes substantially unequal tax burdens upon persons otherwise similarly situated, the tax is unconstitutional.

Applying these principles in
Leonard,
we dismissed a challenge to the higher rate of tax imposed on resident wage earners compared with nonresident wage earners in the City of Philadelphia. We found that a reasonable difference, justifying the disparate treatment, exists between the two classes of wage earners, primarily because residents utilize city-provided services to a greater extent than nonresidents. Likewise, in
Mandl v. Commonwealth, Department of Revenue,
*304
Conversely, in
Columbia Gas Transmission Corp. v. Commonwealth,
Here, the relevant class of taxpayers are those individuals or businesses that lease property within the City of Harrisburg. Applying the test of uniformity to the case at bar, we must decide whether the unequal tax treatment of lessees of public and nonpublic property is based on a legitimate distinction between them. Leonard. The School District identifies only the different impact of real estate taxes upon the lessees as the basis for the classification. According to the School District, the rental rates of lessees of nonexempt property include a share of the owner’s real estate taxes. Therefore, the School District concludes that Resolution 276 “makes a perfectly reasonable distinction between lease transactions that are completely unaffected by real estate taxation.” Appellee’s Brief at 15. We disagree.
First, assuming that real estate taxes affect the two classes of lessees differently, classifications made by other tax legislation cannot remedy the nonuniformity of Resolution 276.
Cf. Commonwealth v. Life Assurance Co.,
Second, “[ajmong the School Board’s considerations in adopting Resolution 276 was its assumption that the consideration paid for leasing tax exempt property does not reflect the payment of real estate taxes by the owner of the property.” R. at 26a (emphasis added). In support of this position, the School District presented the trial testimony of John J. Buckley, Jr., President of Harristown Development Corporation, which leases nonexempt property to retail tenants in the City. He stated that the corporation’s leases contain “pass through” costs, in addition to minimum rent, which allocate to the tenant a share of the corporation’s real estate taxes. R. at 102a-104a. The trial court made no specific findings on this issue. However, assuming the credibility of Mr. Buckley’s testimony, it does not establish any concrete distinction between the rental consideration paid by lessees of exempt and nonexempt property. Although the rental consideration for nonexempt property may incorporate a percentage of the owner’s real estate tax liability, not contained in the rent of exempt property, we will not presume that, in a competitive *306 market, a comparison of the rental rates for nonexempt and exempt property reflects such a difference. 4
Because Resolution 276 distinguishes between lessees of public and nonpublic property, in the absence of a reasonable and just basis for the difference in treatment, we conclude that the tax violates the Uniformity Provision.of the Pennsylvania Constitution. Accordingly, we reverse the Order of the Commonwealth Court.
Notes
. As found by the trial court, the boundaries of the City and the School District are coterminous. More than 42% of the assessed value of all real property in the City is listed as exempt from real estate taxation.
. The City brought this action in equity despite the existence of a statutory remedy pursuant to Section 6 of the Local Tax Enabling Act (LTEA), Act of December 31, 1965, P.L. 157, as amended, 53 P.S. § 6906, which provides, in part:
No tax levied for the first time by any political subdivision to which this act applies shall go into effect until thirty days from the time of adoption of the ordinance or resolution levying the tax. Within said thirty days, taxpayers representing twenty-five percent or more of the total valuation of real estate in the political subdivision as assessed for taxation purposes, or taxpayers of the political subdivision not less than twenty-five in number aggrieved by the ordinance or resolution shall have the right to appeal therefrom to the court of quarter sessions of the county upon giving bond....
No such appeal shall act as a supersedeas unless specifically allowed by the court to which the appeal is taken or a judge thereof.
It shall be the duty of the court to declare the ordinance and the tax imposed thereby to be valid unless it concludes that the ordinance is unlawful or finds that the tax imposed is excessive or unreasonable; but the court shall not interfere with the reasonable discretion of the *299 legislative body in selecting the subjects or fixing the rates of the tax. The court may declare invalid all or any portion of the ordinance or of the tax imposed or may reduce the rates of tax.
53 P.S. § 6906. The City made a good faith, but unsuccessful, attempt to identify twenty-five aggrieved taxpayers pursuant to the LTEA. Nonetheless, both the trial court and the Commonwealth Court assumed equity jurisdiction because of the substantial constitutional challenges to the validity of Resolution 276 and the inadequacy of the statutory remedy. We agree with the Commonwealth Court and do not further address the issue.
Borough of Green Tree v. Board of Property Assessments,
. The legislature has the discretion to exempt certain public property from taxation pursuant to Article VIII, Section 2(a)(iii) of the Pennsylvania Constitution, which provides that ‘‘[t]he General Assembly may by law exempt from taxation ... [t]hat portion of public property which is actually and regularly used for public purposes....”
Township of South Park v. County of Allegheny,
. We also note that the trial court found, but did not discuss, that the individual taxpayers operating businesses on City Island pay to the City approximately $50,000.00 in permit fees.
