Philadelphia homeowners are about to see new property values that could affect their 2027 real estate tax bills.
The City of Philadelphia said the Office of Property Assessment will begin mailing Notices of Valuation for Tax Year 2027 this week, while the Department of Revenue starts a broader outreach campaign to connect homeowners with tax relief programs.
For the median-valued residential property, the city estimates the Real Estate Tax bill change will be about $97 for Tax Year 2027. The final impact depends on each home’s assessed value, tax relief eligibility, and any tax-rate decisions that apply before bills are due.
The notice is not a tax bill, but it starts the review window. Owners should check the new value, confirm property details, look for missing exemptions, and decide quickly whether to request a review or file an appeal.
The First Deadline Comes September 1

Property owners who believe their assessment is wrong can request a First Level Review through the Office of Property Assessment.
The city says the First Level Review application is included with every Notice of Valuation and must be submitted by Tuesday, September 1, 2026.
A formal appeal with the Board of Revision of Taxes has a separate deadline of Monday, October 5, 2026. That option is for owners who believe the city’s value is too high or too low, does not match similar properties, or includes a mistake involving square footage, condition, classification, exemptions, or other property characteristics.
The Homestead Exemption Could Save Many Owners $1,399
Philadelphia’s Homestead Exemption reduces the taxable portion of an owner-occupied home’s assessed value by $100,000.
The city says most homeowners save $1,399 a year on their Real Estate Tax bills through the exemption.
Applications for the 2027 Homestead Exemption are due December 1, 2026. Homeowners who are already enrolled generally do not need to reapply unless ownership has changed, including a deed change after refinancing or adding or removing a co-owner.
Other Relief Programs Target Larger Tax Strain
The city’s outreach campaign also points homeowners to the Real Estate Tax Installment Plan, Senior Citizen and Low-Income Real Estate Tax Freeze programs, LOOP, and the Owner-Occupied Real Estate Tax Payment Agreement.
LOOP may help longtime owner-occupants who have lived in their home for at least 10 years, meet income requirements, and saw their assessment rise by at least 50% in one year or 75% over five years.
The freeze programs can help eligible senior or low-income homeowners keep future tax bills from rising because of assessment or tax-rate increases.
The New Values Take Effect January 1
The city says updated values became available online June 29, 2026. Real Estate Tax bills are scheduled to be mailed December 1, and the new assessments take effect January 1, 2027.
The 2027 Real Estate Tax payment deadline is March 31, 2027.
Before then, homeowners should compare the new assessment with similar nearby properties, confirm whether the Homestead Exemption or other relief appears correctly, and save copies of every appeal, application, notice, and city response tied to the property.
