¶1Opinion by
¶2As authorized by Section 763 of the Judicial Code, 42 Pa. C.S. §763, petitioners seek review of an order of the Board of Finance and Revenue, which sustained a Department of Revenue assessment against petitioners but in doing so declined to rule on a challenge made by petitioners to the constitutionality of Section 314(a) of the Tax Reform Code of 1971 (Code), Act of March 4,1971, P.L. 6, as amended, added by Section 4 of the Act of August 31, 1971, P.L. 369, as amended, *33472 P.S. §7314(a). With respect to the Pennsylvania Personal Income Tax, this section provides:
(a) A resident taxpayer . . . shall be allowed a credit against the tax otherwise due under this article for the amount of any income tax, wage tax or tax on or measured by gross or net earned or unearned income imposed on him by another state with respect to income which is also subject to tax under this article. (Emphasis added.)
¶3Based upon a stipulation of facts filed in this de novo tax appeal, adopted as our findings of fact, it appears that petitioners in their 1975 Pennsylvania individual income tax return claimed in Schedule Gr a tax credit in an amount equal to the Philadelphia City Wage Tax paid to the City that year on income earned and subject to that local government tax. Because of this claimed tax credit and a credit otherwise available for withholding upon Pennsylvania Income Tax on earned wages, petitioners claimed an overpayment of 1975 Pennsylvania Income Tax of $170.00 and sought refund thereof, which was routinely refunded. Upon review of the claimed tax credit producing the overpayment and refund, the Department of Revenue sought repayment of the refund, which was refused. It then recomputed petitioners ’ tax liability and initiated the assessment procedure leading to this appeal. The sole issue raised in the events and administrative proceedings leading to this appeal revolves around Section 314(a) of the Code.
¶4Violation of the uniformity of taxation clause of the Pennsylvania Constitution, Pa. Const, art. VIII, ^l,
¶5*336Initially we note the heavy burden a taxpayer bears when contesting the constitutionality of a taxation statute. Amidon v. Kane, 444 Pa. 38, 51, 279 A.2d 53, 60 (1971). We also recognize that “reasonableness ’ ’ is the standard by which classifications created by a taxation provision are judged and that the legislature has broad discretion in choosing acceptable categories. Commonwealth v. Life Assurance Co. of Pennsylvania, 419 Pa. 370, 376, 214 A.2d 209, 214 (1965). Section 314(a) explicitly distinguishes taxes paid to the Commonwealth from those paid to other “states” as that term is defined in Section 301(t). By implication, it distinguishes taxes paid to the Commonwealth from those paid to local taxing authorities regardless of geographic location. The credit toward state income tax for payment of a local tax which petitioners would have us authorize is not currently granted to any other taxpayer. Section 314(a) allows credit for state imposed taxes analogous to the Pennsylvania Income Tax; it does not recognize a credit for payment of non-Pennsylvania local authority imposed taxes comparable to the Philadelphia Wage Tax paid by petitioners. Indeed the facts presented are comparable to those in Hanek v. Cities of Clairton, 24 Pa. Commonwealth Ct. 69, 354 A.2d 35 (1976), in which a taxpayer sought credit for payment of a tax to the school district where he lived against a wage tax imposed by the township where he worked. There, as here, we conclude that when petitioners question the reasonableness of having to pay the sum of two taxes imposed by different authorities while others pay only one, they are not questioning the uniformity of the taxing provisions but rather the sense of fairness within the legislature which, by authorizing a local wage tax, permits the imposition of two separate and distinct taxes on one income. Two separate taxing schemes superimposed one upon the other do not *337create impermissible, unconstitutional inequalities, Puntureri v. Pittsburgh School District, 359 Pa. 596, 60 A.2d 42 (1948); nor does recognition of credit for taxes paid to some other governmental authority, Minich v. Sharon City, 366 Pa. 267, 270, 77 A.2d 347, 348 (1951). We, therefore, shall affirm the order of the Board of Finance and Revenue.
¶6Order.
¶7Now, September 4, 1979, the order of the Board of Finance and Revenue is affirmed. Accordingly, judgment is entered in favor of the Commonwealth and against Leo and Elizabeth Somma in the amount of $330.00 with interest with credit allowed for 1975 Pennsylvania Income Tax withheld but not for wage taxes paid to the City of Philadelphia.
¶8 Article VIII, Section 1, 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 the general laws.”
¶9 Section 301 (t) provides: “‘State’ means any state or commonwealth of tbe United States, the District of Columbia, the Commonwealth of Puerto Eico, any territory or possession of the United States and any foreign country.”
