For property owners in Philadelphia, the landscape of real estate taxes is about to shift significantly. The City’s Office of Property Assessment (OPA) has completed its citywide revaluation for the 2027 tax year, and the implications for your bottom line could be substantial.
An assessment isn't just a number; it is the foundation of your financial obligation to the city. Whether you own a historic rowhome in Society Hill, a commercial building in Center City, or a multi-family investment in North Philly, understanding the mechanics of this revaluation is essential. If you believe your new assessment does not accurately reflect the current market value of your property, you have the right to challenge it.
At Higgins & Welch Real Estate, Inc., we understand that navigating municipal bureaucracies can be a daunting task. However, with the right information and professional support, you can ensure your property is valued fairly.
Here are the 10 most critical things you should know about the 2027 Philadelphia revaluation and the tax appeal process.
1. What the 2027 Revaluation Actually Means
The Office of Property Assessment (OPA) is responsible for determining the market value of all real property in Philadelphia. The 2027 revaluation is a comprehensive update intended to align assessed values with current market conditions.
It is important to remember that the assessed value is meant to represent what your property would sell for on the open market. If the OPA’s number is significantly higher than what you could reasonably expect to receive in a sale, you likely have grounds for an appeal. This revaluation will directly determine your property tax bill for the 2027 calendar year.
2. Two Distinct Paths for Challenges
Philadelphia provides two primary avenues for challenging an assessment:
- First Level Review (FLR): This is an informal request handled directly by the OPA. It is essentially a request for the city to double-check their math and data.
- Formal Appeal to the Board of Revision of Taxes (BRT): This is a formal legal process. The BRT is an independent body, separate from the OPA, that hears evidence and makes a final determination on the property’s value.
Many housing advocates and real estate professionals recommend filing both simultaneously to ensure your rights are protected across all levels of review.

3. Critical Deadlines You Cannot Miss
The window for filing an appeal is strict and unforgiving. For the 2027 tax cycle, the deadlines are as follows:
- September 1, 2026: Deadline to file a First Level Review (FLR) with the OPA.
- October 5, 2026: Deadline to file a formal Market Value Appeal with the Board of Revision of Taxes (BRT).
Failure to submit your paperwork by these dates generally results in the forfeiture of your right to appeal for that tax year. Mark these dates clearly; the process of gathering evidence can take weeks, so starting early is a necessity.
4. Who Has the Legal Standing to Appeal?
Only an "aggrieved party" can file an appeal. In most cases, this is the owner of record. However, it also includes "equitable owners": individuals or entities who have a contractual right to the property, such as through an executed agreement of sale. If you are in the process of purchasing a property and the assessment appears inflated, you may have the standing to initiate the appeal process before the deed is officially recorded in your name.
5. Identifying the Grounds for Your Appeal
To win a tax appeal, you must prove your case based on specific criteria. The BRT generally looks for one of three things:
- Incorrect Market Value: The assessment is higher than the actual price the property would fetch in a fair sale.
- Lack of Uniformity: Your property is valued significantly higher than similar properties in your immediate neighborhood.
- Incorrect Property Characteristics: The OPA has incorrect data on your property, such as an inflated square footage, the wrong number of units, or a failure to account for severe structural damage.
6. The Burden of Proof is on the Owner
In Philadelphia, the City’s assessment is presumed to be correct unless the property owner provides evidence to the contrary. You cannot simply state that your taxes are "too high." You must present concrete data that supports a lower valuation. This typically includes:
- Recent sales data of comparable properties (comps).
- Photographs of the property’s interior and exterior, especially highlighting defects.
- A professional, independent appraisal.
7. The Power of a Professional Appraisal
While you can represent yourself and provide your own "comps," a professional appraisal carries significantly more weight during a BRT hearing. The Board values the impartial, expert opinion of a certified appraiser who follows the Uniform Standards of Professional Appraisal Practice (USPAP).
Higgins & Welch Appraisers, LLC offers comprehensive valuation services designed specifically to support tax appeal cases. Our team of certified appraisers provides the detailed, data-driven reports necessary to demonstrate a property’s true market value. In many cases, the cost of a professional appraisal is a small investment compared to the potential tax savings over several years.
8. Understanding the BRT Hearing Process
If you file a formal appeal, you will eventually receive a notice for a hearing. These hearings can be held in person at 601 Walnut Street or remotely. During the hearing, you (or your representative) will have the opportunity to present your evidence to a panel of Board members.
The OPA will also have a representative present to defend their assessment. It is a formal proceeding, but the Board members are generally approachable. Being prepared with clear, organized documentation is the single most important factor in a successful outcome.
9. You Must Continue to Pay Your Taxes
A common misconception is that filing an appeal stays your obligation to pay. This is incorrect. You must continue to pay your property taxes based on the challenged assessment while the appeal is pending.
If the BRT eventually rules in your favor and lowers your assessment, the City will issue a credit toward future taxes or, in some cases, a refund. However, failing to pay during the process can result in penalties and interest that may negate the benefits of a successful appeal.
10. Explore Additional Relief Programs
Even if you decide not to appeal, or if your appeal is denied, you may still be eligible for programs that can lower your tax burden. The City of Philadelphia offers several initiatives:
- Homestead Exemption: Reduces the taxable portion of your primary residence’s value.
- Senior Citizen Tax Freeze: For low-income seniors, this "freezes" the tax bill even if assessments or rates rise.
- Longtime Owner Occupant Program (LOOP): Designed for homeowners who have lived in their homes for 10+ years and have seen a massive assessment increase.
These programs can often be applied for through a single application, providing an additional layer of financial protection.
