Center City
High-rise condos, co-ops, historic conversions, and deeded parking as separate assessed items.
Philadelphia Property Tax Appeals
Philadelphia property tax appeal work begins with the Office of Property Assessment, which values every parcel in the city. A Philly tax appeal service then tests that value against sales of similar properties and, when the number is too high, files with the Board of Revision of Taxes.
How a Philadelphia Property Assessment Appeal Works
OPA mails a Notice of Valuation each cycle. The First Level Review deadline for the 2027 tax year is September 1, 2026. The formal BRT deadline is October 5, 2026. Those dates apply citywide. The evidence does not. A Center City condo, a South Philadelphia trinity, and a Northeast twin do not share the same comparable pool.
Why Neighborhood Sales Matter
Philadelphia assessments often drift when OPA leans on sales from a different building type or a hotter block. An appeal is a record of what your property actually is: lot size, finish, parking, abatement status, and the sales that match those facts.
Do You Need a Property Tax Appraisal in Philadelphia?
OPA mails a Notice of Valuation each cycle. The work on this page is to test that value against sales of similar properties. That comparable-sales review is an appraisal-style analysis of the same facts a property tax appraiser would use: building type, lot, condition, and the sales that actually match the house or unit.
A formal bank appraisal is a different product. For a Philadelphia property tax appeal, the appraisal that matters is whether the assessed value tracks the market for that parcel. A property tax appraiser working an appeal file stays inside that question instead of pricing the property for a loan.
If the Notice of Valuation is out of line with those sales, the next step is the First Level Review or a BRT filing, using the same appraisal record already built from the comps.
