About Philadelphia Property Assessments
The Office of Property Assessment (OPA) determines the market value of every property in Philadelphia. Real estate taxes are calculated by applying the combined City and School District rate — currently 1.3998% — to the taxable assessed value.
For the 2027 tax year, OPA has published updated assessments. Property owners who disagree with their assessment may file an appeal with the Board of Revision of Taxes (BRT). The deadline to appeal a 2027 assessment is the first Monday in October 2026.
Tax estimates on this page use the published 1.3998% rate applied to the taxable assessed value from OPA records. Actual bills may differ due to abatements, exemptions, payment agreements, or future rate changes. Always verify your bill at the Philadelphia Tax Center.

Each year, Philadelphia's Office of Property Assessment (OPA) establishes assessed market values for every parcel in the city. Those values are the foundation of your real estate tax bill: the higher the assessed value, the higher your estimated tax liability.
The lookup tool on this page compares the OPA-published 2026 and 2027 assessed market values for your property and estimates the resulting change in annual real estate tax. Two numbers matter most for owners of larger commercial and income-producing properties:
- Dollar assessment change — the raw increase or decrease in assessed market value between 2026 and 2027.
- Estimated annual tax-dollar change — the estimated change in your annual real estate tax bill, calculated using the current Philadelphia tax rate of 1.3998%.
For a large commercial building, even a modest percentage increase in assessed value can translate into tens of thousands of dollars in additional annual tax. Knowing the dollar impact early gives owners and their advisors time to evaluate options before deadlines pass.
Note: Tax estimates on this page are approximations based on OPA assessed values and the published tax rate. Actual tax liability depends on applicable exemptions, abatements, and other factors. Verify your actual bill at the Philadelphia Tax Center.
Assessment Increase vs. Grounds for Review or Appeal
A large assessment increase — or a large estimated tax increase — does not by itself establish valid grounds for a challenge. The size of the change is not the legal standard.
Philadelphia property owners may challenge an OPA assessment based on legitimate valuation or property-specific issues. Common grounds that professionals evaluate include:
- The assessed value does not accurately reflect the property's actual market value.
- Errors in recorded property characteristics (square footage, building class, condition).
- Comparable properties in the same area are assessed at materially lower values (uniformity).
- For income-producing properties, the income approach to value produces a materially different result than the OPA assessment.
This is not legal advice. Whether a specific property has valid grounds for a challenge is a factual and legal question that requires review by a qualified professional — typically a tax appeal attorney or a certified real estate appraiser with Philadelphia experience.
First Level Review and Formal BRT Appeal
Philadelphia offers two distinct processes for challenging an OPA assessment:
First Level Review (FLR)
An informal administrative review conducted by OPA. Property owners submit a request for reconsideration directly to OPA, which then reviews the assessment internally. The FLR is typically the first step and does not require a formal hearing. OPA may adjust, confirm, or increase the assessment following its review.
Board of Revision of Taxes (BRT) Appeal
A formal quasi-judicial appeal before the Board of Revision of Taxes, an independent body that hears evidence and issues decisions on assessed value. BRT appeals typically involve a hearing at which the property owner (or their representative) presents valuation evidence. The BRT may reduce, confirm, or increase the assessment.
2027 Assessment Deadlines
The deadline to file a First Level Review (FLR) with OPA and the deadline to file a formal appeal with the Board of Revision of Taxes (BRT) for the 2027 tax year is October 5, 2026. Confirm current deadlines directly with OPA and the BRT before filing, as procedures and dates can change.
Commercial Property Considerations
Owners and operators of commercial, multifamily, hotel, mixed-use, and other income-producing Philadelphia properties deserve particular attention when assessment values change — for several reasons:
- Dollar magnitude. A 10% assessment increase on a $5 million commercial property represents a $500,000 change in assessed value and roughly $7,000 in additional annual tax. The same percentage increase on a $50 million property is an order of magnitude larger.
- Valuation methodology. Large income-producing properties are often most accurately valued using the income approach — capitalizing net operating income — rather than the comparable-sales approach OPA may apply. A professionally prepared income-approach analysis can be compelling evidence in a BRT appeal.
- Property characteristics. Errors in OPA's records — incorrect square footage, wrong building class, inaccurate condition rating — can inflate assessed values. These are worth verifying against actual property data.
- Classification. How OPA classifies a property (category code) affects how it is valued. Misclassification can result in an assessment that does not reflect the property's actual use or market.
- Uniformity. Pennsylvania law requires that assessments be uniform across comparable properties. If similar properties in the same area are assessed at materially lower values, that disparity may support a challenge.
None of the above means any particular property qualifies for a successful appeal. Each situation is fact-specific. The appropriate starting point is a review by a qualified tax appeal professional.

Frequently Asked Questions
How do I find my Philadelphia 2027 property assessment?
Enter your property's street address and ZIP code in the lookup tool at the top of this page. The tool queries the OPA database via OpenDataPhilly and returns both the 2026 and 2027 assessed market values for your parcel.
How is Philadelphia property tax estimated?
Philadelphia real estate tax is calculated by multiplying the assessed market value by the current tax rate (1.3998% for 2026 and 2027). The estimates on this page apply that rate to the OPA assessed value. Your actual bill may differ based on exemptions, abatements, and other factors — verify at the Philadelphia Tax Center (philtax.phila.gov).
Does a higher assessment automatically mean I should appeal?
No. A higher assessed value or larger estimated tax bill does not by itself establish valid grounds for an appeal. Valid grounds typically involve a demonstrable valuation issue — such as an assessed value that does not reflect actual market value, errors in property characteristics, or lack of uniformity with comparable properties. A qualified tax appeal professional can evaluate whether your situation warrants a challenge.
What is a First Level Review?
A First Level Review (FLR) is an informal administrative review offered by OPA that allows property owners to request reconsideration of their assessed value before filing a formal BRT appeal. It is typically the first step in the challenge process. The FLR deadline for the 2027 tax year is October 5, 2026.
What is the Board of Revision of Taxes?
The Board of Revision of Taxes (BRT) is the independent quasi-judicial body in Philadelphia that hears formal appeals of OPA property assessments. Property owners present valuation evidence at a BRT hearing, and the Board issues a decision on whether the assessed value should be changed.
What is the deadline to challenge a 2027 Philadelphia assessment?
The deadline to file both a First Level Review (FLR) with OPA and a formal appeal with the BRT for the 2027 tax year is October 5, 2026. Confirm current deadlines directly with OPA and the BRT before filing.
Can commercial property owners challenge an assessment?
Yes. Owners of commercial, multifamily, hotel, mixed-use, and other income-producing properties may challenge their OPA assessment through the FLR and BRT processes. Commercial appeals often involve income-approach valuation analysis, comparable property data, and review of property characteristics, and typically benefit from representation by a qualified tax appeal attorney or certified appraiser.
