Zilka v. Tax Review Bd. City of Phila. (majority)
Annotate this CaseIn April 2017 and June 2017, Appellant Diane Zilka filed petitions with the Philadelphia Department of Revenue (the “Department”), seeking refunds for the Philadelphia Tax she paid from 2013 to 2015, and in 2016, respectively. During the relevant tax years, Appellant resided in the City, but worked exclusively in Wilmington, Delaware. Thus, she was subject to four income taxes (and tax rates) during that time: the Philadelphia Tax; the Pennsylvania Income Tax (“PIT”); the Wilmington Earned Income Tax (“Wilmington Tax”); and the Delaware Income Tax (“DIT”). The Commonwealth granted Appellant credit for her DIT liability to completely offset the PIT she paid for the tax years 2013 through 2016; because of the respective tax rates in Pennsylvania versus Delaware, after this offsetting, Appellant paid the remaining 1.93% in DIT. Although the City similarly credited against Appellant’s Philadelphia Tax liability the amount she paid in the Wilmington Tax — specifically, the City credited Appellant 1.25% against her Philadelphia Tax liability of 3.922%, leaving her with a remainder of 2.672% owed to the City — Appellant claimed that the City was required to afford her an additional credit of 1.93% against the Philadelphia Tax, representing the remainder of the DIT she owed after the Commonwealth credited Appellant for her PIT. After the City refused to permit her this credit against her Philadelphia Tax liability, Appellant appealed to the City’s Tax Review Board (the “Board”). The issue this case presented for the Pennsylvania Supreme Court's review as whether, for purposes of the dormant Commerce Clause analysis implicated here, state and local taxes had to be considered in the aggregate. The Court concluded state and local taxes did not need be aggregated in conducting a dormant Commerce Clause analysis, and that, ultimately, the City’s tax scheme did not discriminate against interstate commerce. Accordingly, the Court affirmed the Commonwealth Court order.
