53 Pa. Stat. § 6924.305
If, subsequent to the passage of any ordinance or resolution under the authority of this chapter, the General Assembly shall impose a tax or license fee on any privilege, transactions, subject or occupation, or on personal property or on sales of admission to places of amusement or on sales or other transfer of title or possession of property taxed by any such political subdivision hereunder, the act of Assembly imposing the State tax or license fee thereon shall automatically vacate the ordinance or resolution passed under the authority of this chapter as to all taxes accruing subsequent to the end of the current fiscal year of such political subdivision. It is the intention of this section to confer upon such political subdivision the power to levy, assess and collect taxes upon any and all subjects of taxation, except as above restricted and limited, which the Commonwealth has power to tax but which it does not tax or license, subject only to the foregoing provision that any tax or license shall automatically terminate at the end of the current fiscal year of the political subdivision.
