A panel of the Commonwealth Court held that a taxpayer failed to prove that he was a nonresident of Pennsylvania in 2005. Lust v. Commonwealth, No. 645 F.R. 2011 (Pa Commw. Jan. 9, 2015) (unreported). The taxpayer filed Pennsylvania, New York and New Jersey tax returns reflecting part year residency in Pennsylvania in 2005. Several years later, the taxpayer filed an amended Pennsylvania return claiming nonresidency for the entire year. The court stated that, when asked about the conflicting documentary evidence on cross examination, the taxpayer was evasive, repeatedly declined to identify documents that he had filed, would not confirm information contained therein, testified that he could not remember critical facts, and provided only the most basic information. The court found the taxpayer’s testimony not credible and held that he had failed to prove nonresidency in Pennsylvania.
