Philadelphia's $1,400 tax break: who has it, and who can still claim it

The Office of Property Assessment (OPA) has property-level detail on its website: what a property is zoned for, what it is assessed as, and whether it has a homestead exemption. Using a combination of that and the OpenDataPhilly dataset, I pulled all 664,907 property records in the city and picked out the ones that are single family homes, detached or rowhome. About 453,901 of them. Roughly 125,000 of those are not owner-occupied (rentals, second homes), which leaves 328,429 homes that can actually file. 223,710 of those already have the exemption on file.

About 68% of eligible homeowners are using the exemption. That means about 104,719 homes where the owner-occupant is missing out on one of the best tax exemptions Philly offers.

The Homestead Exemption is pretty simple: For any owner-occupied primary residence, the owner gets no property taxes on the first $100,000 of the house's assessed property value. At the current residential tax rate of 1.3998%, that's $1400/year post-income tax, or like having $2000/year added to your paycheck.

In doing this work, I excluded condominiums and apartments to make the analysis simpler; their shared ownership structure makes both ownership and occupancy difficult to pin down. OPA tracks property at the parcel level while the tax exemption applies to individual units, so it was impossible for me to figure out which units in multi-unit buildings are eligible vs not for the homestead exemption.

I matched mailing addresses to the property address to estimate owner-occupied status, not perfect but a decent proxy that I manually door-knocked to spot check. And while I understand some landlords either intentionally or accidentally leave their business mailing to that same rental property, it was a useful proxy for this work and I estimate it's between 70-90% right. Moreover, to check whether that methodology was way off, I looked at the homes that already had the exemption on file. For 94.7% of them, the mailing address matched the property address, so I used that as a sign that my assumption was good enough to be practical (and yes, I understand adverse selection bias, and covariance.)

One thing that caught my eye - both poor and rich zips are missing out on the exemption, kind of equally

Ex ante, I expected poorer zips to have more homes missing out, because owners may be less informed, have less technology access, or simply have less time to fill out one more government form. But nope, there are some rich zips with dismal exemption rates - 19146 has 47.8% of eligible homes missing out - and, conversely, there are some blocks with similar incomes who have widely different exemption rates (i.e., 19115 has 15.1% of eligible homes missing out on the exemption, whereas 19145 has 32.4% missing out, despite both having a median household income within 3% of one another.)

That is both good and bad news. The good news is the "missing out" is not inequitable in the way many government programs are inequitable, where the rich are more likely to take advantage of benefits than the poor, because of better awareness or access. The bad news is that everyone is missing out on one of the best tax breaks Philly offers.

The homestead exemption has no qualifications other than being an owner-occupant, and it's crazy easy to apply for

Unlike most other tax breaks which have means tests, the Homestead exemption has no income limit, no age limit, no filing fee. It does not matter if you are in an opportunity zone like Kensington, a gentifying area like Fishtown, or the upper income areas around Rittenhouse. If you're an owner-occupant, you qualify.

How to apply for the Homestead Exemption

1. Check whether you already have it. The city’s property search at property.phila.gov will tell you, and it takes about a minute.
2. Apply. Three ways. Online, through the Philadelphia Tax Center, and you do not need to make an account to submit. Or by phone, on the Homestead Hotline at (215) 686-9200. Or by mail on the paper form to the Department of Revenue, PO Box 52817, Philadelphia, PA 19115. December 1 is the final deadline to apply for the exemption at all; if you want it on your regular tax bill rather than a second bill, apply by October 1.

If you've read this far, you're probably astounded that so many people are missing out. So was I - that's why I'm working with several RCOs to organize a physical door knocking and sign-up campaign

Notes, Sources, and Methodology

I pulled the City of Philadelphia’s Office of Property Assessment property and assessment history dataset in October 2026. This is a city-run program administered through the Tax Center and Department of Revenue, not the state program. As an outside check, the exemption count matches the Economy League’s figure for the same program to within about 2%.

I did not use OPA’s own “category” field to identify single family homes, because it is not reliable: it tags 1,806 properties in ZIP 19102 as single family where the Census counts 34 owner-occupied single-family homes, because a converted rowhouse keeps the tag it was given when the building was built. I built the category by matching the building description to exclude condominiums, apartments and vacant land instead.

I excluded condominiums and apartments from both the numerator and the denominator, because OPA stores one exemption flag per parcel. Pennsylvania grants the exemption per dwelling, so a fifty-unit condo in which forty owners have all filed still shows a single yes, and there is no way to tell that building from one where nobody has filed. Measured across all owner-occupied homes rather than single family homes alone, the citywide share missing is 30.8%, close to the 31.9% reported here.

Six ZIP codes are not reported because each has fewer than 200 qualifying homes: 19102 has 66 because it is overwhelmingly apartments, 19112 has 10, and 19105, 19108, 19109 and 19110 hold six homes between them. Those last four are USPS ZIP codes carrying almost no property records, and the four filed under 19109 are all the same building, 123 S Broad Street, in Center City. They appear gray on the map.
