53 Pa. Stat. § 6924.306
Prior to the passage of any ordinance or the adoption of any resolution imposing a tax or license fee under the authority hereunder granted, such political subdivision shall give notice of the intention to pass such ordinance or adopt such resolution. Such notice shall be given in addition to all other notices required by law to be given and shall set forth the substantial nature of the tax or license fee to be imposed by the proposed ordinance or resolution, the reason which, in the judgment of the officials of the subdivision, necessitates the imposition of the tax, and the amount of revenue estimated to be derived from the tax. Publication of such notice shall be made by advertisement once a week for three weeks in a newspaper of general circulation within such political subdivision if there is such newspaper and, if there is not, then such publication shall be made in a newspaper of general circulation within the county in which the advertising political subdivision is located.
Every such tax shall continue in force on a calendar or fiscal year basis, as the case may be, without annual reenactment unless the rate of the tax is subsequently changed.
