PHILADELPHIA PROPERTY TAX OVERVIEW
Property Tax Appeals in Philadelphia, Pennsylvania
Philadelphia is the statutory exception to almost everything else in Pennsylvania assessment practice. It is a consolidated city and county, so there is no separate county assessor and no county Board of Assessment Appeals. Valuations are set by the Office of Property Assessment (OPA), and appeals are heard by the Board of Revision of Taxes (BRT). The commercial inventory the OPA has to value is unusually varied for a single jurisdiction: Center City office towers working through a difficult leasing cycle, University City lab and life-science space carrying specialized improvements, the Navy Yard's mixed campus of office, research, and industrial buildings, large-format industrial and logistics product in Northeast Philadelphia and Port Richmond, and dense retail and mixed-use blocks in Fishtown and South Philadelphia. Mass appraisal has to reduce all of that to a modeled value, and for commercial owners the model is frequently wrong in an expensive direction. Owners comparing their situation to the rest of the state should start with our Pennsylvania commercial property tax appeal overview and then work through the Philadelphia-specific rules below.
The most important difference is how value is set. Most Pennsylvania counties hold a frozen base year, sometimes for decades, and use the annually published Common Level Ratio to convert a property's current market value into an assessed value. Philadelphia does not work that way. The OPA revalues at (or near) full current market value, which means the ratio machinery that dominates appeals elsewhere in the state plays a much smaller role here. A Philadelphia appeal is a direct argument about what your building is worth today, supported by an appraisal, comparable sales, rent rolls, and operating statements. That makes the gap between assessed value and market value the whole case rather than one input into a formula. It also means a citywide revaluation can move your assessment sharply in a single year, with no base-year cushion to absorb it. The annual filing date is the first Monday of October for the following tax year, and a change-of-assessment notice opens its own 40-day window, so track both against the other property tax appeal deadlines in the states we serve. Philadelphia also offers a first-level review request through the OPA, which runs separately from the formal appeal. It is worth pursuing, but a formal BRT appeal should still be filed to preserve your rights, and from the BRT a case can be taken to the Court of Common Pleas.
Philadelphia is a consolidated city and county: appeals go to the Board of Revision of Taxes, not a county board
The Office of Property Assessment values at or near full current market value, not a frozen base year
The Common Level Ratio carries far less weight here than in the rest of Pennsylvania
Annual deadline is the first Monday of October, and a change-of-assessment notice opens a separate 40-day window
First-level review runs separately from the formal BRT appeal and does not preserve your rights on its own

PHILADELPHIA TAX CHALLENGES
Why Philadelphia Commercial Properties Are Over-Assessed
Market-Value Revaluation
Because the Office of Property Assessment tracks current market value instead of holding a base year, a modeling error lands on your bill immediately. There is no stale base-year figure cushioning the increase.
Office Market Dislocation
Center City office values have moved faster than assessment models. Buildings with real vacancy, concession-heavy leases, and pending capital needs are routinely valued as though the prior leasing market still holds.
Specialized Improvements
University City lab space, Navy Yard research buildings, and converted industrial product in Port Richmond carry improvements that mass appraisal treats as pure added value rather than tenant-specific cost.
A Deadline Unlike the Rest of PA
Philadelphia files on the first Monday of October while most Pennsylvania counties close in August or September. Owners holding property in several counties miss the city date precisely because it is different.

WHY PHILADELPHIA OWNERS TRUST EPTA
Board of Revision of Taxes Appeals, Handled End to End
A Philadelphia appeal is won or lost on the valuation record. Because the city assesses toward current market value, there is no ratio argument to fall back on: you have to show the Board of Revision of Taxes a better-supported conclusion about what the property is worth, using comparable sales, rent rolls, operating statements, and evidence of vacancy, condition, or functional obsolescence. Our team has spent nearly two decades building exactly that kind of record for commercial owners, and we manage the whole sequence: the free review, the filing, the first-level review request where it helps, the BRT hearing, and escalation to the Court of Common Pleas when the board's number does not hold up. Working with an experienced commercial property tax consultant matters most in a jurisdiction like this one, where the rules differ from everything around them and the city defends its values seriously.
Philadelphia appeals are filed with the Board of Revision of Taxes, not with a county Board of Assessment Appeals, because the city and the county are one consolidated government. The appeal asks the BRT to find that the Office of Property Assessment overstated your property's market value, so the case rests on an appraisal, comparable sales, rent rolls, and operating statements rather than on a ratio calculation. EPTA prepares the filing, assembles the valuation evidence, and represents you at the hearing. If the board's decision falls short, the matter can be taken to the Court of Common Pleas. Start with a free review of your assessment well before the October filing date.
Philadelphia's annual appeal deadline is the first Monday of October, for the following tax year. That is later than the August 1 or September 1 dates used across most of Pennsylvania, which is exactly why owners with property in several counties tend to miss it. Separately, if the city mails you a change-of-assessment notice, you generally have 40 days from that notice to appeal, regardless of the annual date. Because the city occasionally adjusts its schedule around a citywide revaluation, confirm the current year's date directly with the Board of Revision of Taxes rather than assuming it. Our property tax appeal deadline guide tracks filing windows across every state we serve.
Far less than it does in the rest of the state. Most Pennsylvania counties hold a frozen base year and rely on the Common Level Ratio to translate a property's current market value into an assessed value, which makes the ratio a central battleground in those appeals. Philadelphia's Office of Property Assessment instead revalues at or near full current market value, so there is no long-stale base-year figure to convert. The practical effect is that a Philadelphia case is a direct argument about present-day worth: prove the market value is lower and the assessment follows. If you also own property elsewhere in the state, read how the base-year and Common Level Ratio system works across Pennsylvania before you assume the same strategy applies.
Philadelphia offers a first-level review request, handled by the Office of Property Assessment, which is an informal reconsideration of the valuation on your parcel. It runs on a separate track from the formal appeal and is not a substitute for it. A first-level review can be denied, or can simply run past the annual filing date, leaving an owner with no route back in for that tax year. The safe approach is to file the formal BRT appeal to preserve your rights and treat the first-level review as an extra chance to resolve the value early. Our DIY versus professional appeal comparison walks through where owners most often lose ground on procedure alone.
We represent owners across the full commercial spectrum in Philadelphia. That includes Center City office towers working through a difficult leasing cycle, University City lab and life-science space, Navy Yard research and campus buildings, industrial and logistics facilities in Northeast Philadelphia and Port Richmond, and retail properties in Fishtown and South Philadelphia. We also handle apartment and multifamily assets throughout the city. Each of these carries valuation issues that mass appraisal flattens out, and lab conversions in particular are difficult to value from sales data alone.
Yes, and in Philadelphia it is often the highest-value moment to look. Because the city assesses toward current market value rather than a frozen base year, a recorded sale is highly visible to the Office of Property Assessment and frequently shows up in the next assessment cycle. A purchase price is not automatically the market value of the real estate: portfolio allocations, assumed above-market leases, deferred capital needs, and business value bundled into a deal can all push a price above what the building itself is worth. New owners should have the assessment reviewed in the first year of ownership and file by the first Monday of October if the number is overstated. Our guide to appealing property taxes after a purchase covers the evidence buyers need to assemble.
EPTA works primarily on a contingency basis. Beyond a modest filing retainer that covers filing fees and case costs up front, you pay our fee only if we reduce your assessment and save you money. In Philadelphia, where city and school district levies both ride on the same valuation, a meaningful reduction in market value translates directly into recurring annual savings rather than a one-year benefit. Because the city revalues periodically instead of holding a base year, keeping the assessment accurate is an ongoing exercise across successive cycles. See our property tax appeal cost guide for how the retainer and the contingency fee fit together.
Philadelphia is the most procedurally distinct assessment jurisdiction in Pennsylvania, and the city defends its valuations with experienced staff and outside counsel. A BRT hearing is a valuation proceeding: you need a supportable market value conclusion, credible comparables, and income evidence presented in the form the board expects to see. Owners who appear without that record usually leave with the assessment unchanged, and the annual deadline means a weak first attempt costs a full tax year. Professional representation on a contingency basis ties the cost of building the case to the result it produces.
