All Philadelphia, PA commercial properties have been reassessed for tax year 2018. The official notices will be mailed on April 14, 2017. The appeal deadline for the First Level Review will be approximately 30 days from the notice date. The Board of Revision deadline will be October 2, 2017. For tax year 2019 and forward, the City plans to do annual reassessments of all the properties. It should be noted that Philadelphia is exempt from the state law requiring reassessments to be revenue-neutral, so despite increasing assessments, the millage rate will not necessarily go down.
