In Air Products & Chemicals, Inc. v. Board of Assessment Appeals, 720 A.2d 790 (Pa. Cmwlth. 1998), this court held that interest on a real property tax refund is not due from the date of overpayment but, rather, from the date of the court order resolving the dispute. However, the holding in Air Products has been superseded by statute. Section 8426(a) of the Local Taxpayers Bill of Rights Act, which became effective on January 1, 1999, states that "overpayments of tax due a local taxing authority, including taxes on real property, shall bear simple interest from the date of overpayment until the date of resolution." 53 Pa.
