Experience
- Represented multistate corporations in challenging Pennsylvania’s Cost of Performance sourcing methods;
- Represented multistate corporations in litigating whether they had a taxable nexus in the City of Philadelphia or the Commonwealth of Pennsylvania;
-
Successfully argued to the Pennsylvania Supreme Court that taxpayers were entitled to a credit on overpayments of estimated Philadelphia Business Privilege Tax which resulted from adjustments made through a Revenue Agent Report pursuant to an Internal Revenue Service audit. The City of Philadelphia unsuccessfully argued that the three- year statute of limitations should apply both to refunds and to credits. Ruling in the taxpayers’ favor, the Court accepted Jennifer’s argument that the statute only provided for a statute of limitations for refunds, not credits, and therefore the taxpayer was entitled to credits for the overpayments; and
Successfully argued that a local Business Privilege Tax imposed on fees paid by Pennsylvania franchisees to an out-of-state company’s regional office in the township was unconstitutional because it was not fairly apportioned. The court found that the township taxed all of the charges from franchise stores in Pennsylvania, even though the activity that generated the Pennsylvania charges resulted from economic activity from both in and outside Pennsylvania.
