Most Philadelphia homeowners will see slightly higher property tax bills next year after the city conducted a mass reassessment process that resulted in a modest uptick in home values.
But for thousands of residents, many of whom live in North Philadelphia, next year’s tax bills are expected to soar.
Nearly 6,000 homeowners in Philadelphia saw their property assessments this year climb by more than 50% compared with two years ago, the last time the city conducted a mass revaluation, according to an Inquirer analysis of city property assessment data released in June.
Of those homeowners, more than 2,200 saw their assessments more than double.

That is likely to result in sticker stock come tax time next year, because property tax bills in the city are calculated based on home values. The revenue is split between the city and the Philadelphia School District.
Homeowners across the city saw a median 3% increase in their property assessments this year compared with the 2025 tax year. Jumps were higher in neighborhoods that border gentrifying areas, such as in parts of Kensington and West Philadelphia.
But this year, two other areas of the city had the densest concentrations of homes where property assessments increased by 50% or more, according to The Inquirer’s analysis.
The steep rises are clustered in the southern end of Strawberry Mansion, the historically Black neighborhood along the Schuylkill, and in the tiny Hartranft neighborhood north of Temple University and east of Broad Street, where residents are predominately Latino.
Housing experts and advocates for low-income homeowners have long criticized the city’s assessment system as systemically biased, leaving Black and brown homeowners to pay disproportionately high property taxes. Mayor Cherelle L. Parker convened a task force in 2024 to study the city’s revaluation system, and that group’s recommendations are expected to be released later this year.
Monty Wilson, a senior attorney at Community Legal Services who sits on the task force, said the Philadelphia Office of Property Assessment is the best in the state and has “worked really hard to become more and more accurate.”
But he said bias persists in part because of the unique challenges that assessors face in low-income neighborhoods that can cause volatility in home values, such as higher rates of vacant lots, foreclosures, and other factors.
A 2024 CLS report found that errors were clustered in lower-value neighborhoods where a majority of residents are people of color.
“That means when a property is overassessed,” Wilson said, ”it tends to occur in a Black and brown neighborhood.”
The Parker administration did not respond to requests for comment.
In response to a previous article about this year’s property reassessments, city officials emphasized that some lower-income homeowners pay relatively low tax bills because of the popular homestead exemption tax break. The program, which any homeowners can apply for and obtain if they live in their house as their primary residence, exempts the first $100,000 from a home’s taxable value.
That means that some homeowners in working-class neighborhoods previously paid little to no property taxes. A sudden increase in valuation, like the ones seen this year in pockets of North Philadelphia, could require they pay bills next year that are several hundred dollars more than in the past.
Take the 2500 block of North Marshall Street. The residential North Philly street sits between West Kensington and Broad Street, and nearly every home saw its assessment increase by 60% or more, according to The Inquirer’s analysis.
Most of the homes there had previously been valued at less than $100,000, meaning owners with the homestead exemption owed no property taxes. Now, many of the homes on the block are valued at about $140,000, an amount that would next year yield more than $500 in yearly tax bills for owners with the homestead exemption.
More than 40% of the Hartranft neighborhood’s residents are below the federal poverty level, which is $33,000 a year for a family of four, according to U.S. Census data.
City Councilmember Quetcy Lozada, whose district includes parts of Kensington and North Philadelphia, said the Hartranft area is not like sections of Kensington that have seen an influx of development in recent years and where increases in property assessments may be expected.
It is possible, she said, that lower-income residents who have been displaced from parts of Kensington looked to move west of the neighborhood, increasing demand in the Fairhill and Hartranft areas.
Lozada — who has held workshops in the neighborhood to connect residents with property tax relief programs — said she fears her constituents are being asked to pay disproportionately high taxes and not seeing better city services and stronger public schools.
“How is it possible that someone in Fairhill is paying a higher tax for a property that has not had any investment, in a neighborhood that is not as safe, whose school system is not as great, as somebody that lives in Chestnut Hill, for instance?” she said, referring to the upscale Northwest Philadelphia neighborhood with a $109,000 median household income. “There has to be a better way of doing a more accurate evaluation in every neighborhood.”
City Council is expected to hold a hearing this fall to probe the assessment process.
In Strawberry Mansion, community leaders said that increased assessments are likely a result of market pressure from Brewerytown to its south, a comparatively whiter and higher-income neighborhood.
“The city has to be super transparent about this assessment system so people can better understand it and not feel that sticker stock,” said Tonnetta Graham, president of the Strawberry Mansion Community Development Corp. “If we know how they came to their number, it’s easier to chew.”

Councilmember Jeffery Young Jr., whose district includes both Strawberry Mansion and parts of Hartranft, did not respond to requests for comment.
Jalon Alexander, a Strawberry Mansion native who this month launched a campaign to challenge Young for his Council seat next year, said he was recently at a block party in the neighborhood where he heard repeatedly from older homeowners who were concerned about their increased assessments.
“They feel taken advantage of, and they feel like it’s coming out of nowhere,” Alexander said. “This is an area where there’s high levels of poverty, and there is not a lot of political or government attention in this area. I’ve spoken with many people whose rates have almost doubled. It’s the biggest issue in the neighborhood.”
What to know about your tax bill
New property assessments will take effect on Jan. 1, and property tax bills are due each year by March 31.
Owners who believe that their properties were assessed too high can appeal to the Philadelphia Board of Revision of Taxes by Oct. 5. Informal reviews intended to correct obvious errors can also be requested through the Philadelphia Office of Property Assessment.
Owners whose home is their primary residence can have the taxable portion of their property’s assessed value reduced by $100,000 through the homestead exemption, which saves homeowners an average of $1,400 a year. Sign up for the free program here.
Additional tax relief programs include freezes for seniors and low-income people, as well as for homeowners who have lived in their residence for more than 10 years and have seen large jumps in property value over a short time period.
