Property Taxes in the Philadelphia Suburbs: County-by-County Breakdown
Property Taxes in the Philadelphia Suburbs, A County-by-County Breakdown
Executive Summary: Property taxes in the Philadelphia suburbs vary significantly based on the county, municipality, and especially the school district where a home is located. Two homes can be in the same county, or even the same general municipality, but fall into different school districts and carry very different tax bills. Rather than comparing millage rates alone, buyers should compare the effective tax rate and verify the actual tax bill for any home they're considering. In this guide, we'll show you how to do both.
You're comparing homes across the Philadelphia area, but property taxes are confusing because there isn't one statewide rate. You are worried that you'll find a home you love, only to discover it won't fit the budget because you underestimated the property taxes and the actual monthly costs are higher than expected. Rates are set separately by county, municipality, and school district, and layered together, so the number you see on Zillow or a third-party estimator often isn't the number you'll actually pay.
At Premier Home Team, we have helped hundreds of families in the Greater Philadelphia area. We help buyers compare homes across Philadelphia, Delaware, Chester, Montgomery, and Bucks Counties, where crossing a township or school district line can make a meaningful difference in the tax bill.
This guide breaks down what buyers actually need to understand: how the numbers are built, how Philadelphia, Delaware, Chester, Montgomery, and Bucks Counties compare, and how to estimate what you'd really pay on a specific home before you fall in love with it.
Millage Rate vs. Effective Tax Rate: What Is the Difference?
Before comparing counties, it helps to know what you're comparing. Pennsylvania property tax is built from three layers, county mills, municipal mills, and school district mills. These are added together into a combined millage rate, then applied per $1,000 of a property's assessed value.
The catch is that "assessed value" is rarely the same as market value. Each county uses a Common Level Ratio (CLR), set annually by the PA Department of Revenue, to convert assessed value back to an implied market value. That's why Bucks County's millage numbers look enormous compared with Chester or Montgomery Counties. Bucks County assesses homes at a much smaller share of market value, so its millage rates aren't directly comparable. Comparing raw millage rates across counties without accounting for this is comparing apples to oranges.
To make an honest comparison, we've converted each county's combined millage into an effective tax rate on market value, the percentage of a home's actual worth you'd pay annually in property tax. That's the number in the table below.
How we calculated these comparisons: We used each county's official 2026 tax rate data and Pennsylvania's Common Level Ratio to estimate an effective tax rate on market value. Our sources include:
- Delaware County's Treasurer's office Tax Rate chart
- Chester County's Assessment office Millage Chart
- Bucks County's Board of Assessment Millage Rates chart
- Montgomery County's Board of Assessment Appeals millage table
The "typical effective rate" is the simple average of the effective rates we calculated across the ZIP codes analyzed in each county: 37 ZIPs in Delaware County, 17 in Chester, 29 in Montgomery, and 6 in Bucks. The averages are not weighted by population or number of homes. Each ZIP was mapped to its primary municipality and school district; because some ZIPs cross municipal or school district boundaries, these figures should be used as planning estimates rather than precise county-wide statistics. The range shows the lowest and highest calculated rates among the ZIPs analyzed.
Philadelphia uses its flat combined city-and-school rate (1.3998%) applied to Actual Value Initiative (AVI) assessments, which are already set at market value. Actual property taxes on any individual home will vary by assessed value, exemptions, and reassessment, so treat these as planning estimates, not a bill.
Delaware vs. Chester vs. Montgomery vs. Bucks vs. Philadelphia
| Area | Typical Effective Rate | Approx. Tax on a $400K Home* | What Buyers Should Know |
| Delaware County | ~1.99% (range ~0.97%–3.29%) | ~$7,950 | Widest spread of the four counties; a home in Thornbury Township can carry roughly a third of the tax burden of a similarly priced home in Darby Borough, almost entirely driven by the school district. |
| Montgomery County | ~1.58% (range ~0.57%–2.26%) | ~$6,300 | Also a wide range. Bryn Athyn Borough's small, independently funded school district sits near the bottom, while Cheltenham Township is among the highest in the collar counties. |
| Bucks County | ~1.47% (range ~1.37%–1.65%, based on available official data) | ~$5,900 | Millage numbers look shocking at first glance (150–280+ mills) because of an unusually low assessment ratio, the effective rate on market value is actually mid-pack. |
| Chester County | ~1.42% (range ~1.00%–2.07%) | ~$5,680 | Generally the most moderate of the four counties, though Coatesville Area SD runs notably higher than West Chester Area SD or Great Valley SD zips just a few miles away. |
| Philadelphia | 1.3998% (flat combined city + school rate) | ~$5,599 | The simplest to calculate. One flat rate applied to assessed market value, no township or school district layer to account for. |
*Estimates based on effective rate applied to a $400,000 market value; actual bills depend on a home's specific assessment, municipality, and school district.
Why Two Similarly Priced Homes Can Have Very Different Property Taxes
This is the part a spreadsheet can't really explain, but it's the most important thing to understand before you compare listings. School district lines don't follow ZIP codes, and they frequently don't follow what feels like a natural town boundary either.
Bryn Mawr is a good example: homes with the same 19010 ZIP code can fall in different townships and school districts, which can make a meaningful difference in their property tax bills.
| Home A – 19010 (709 Moore Ave) |
Two Delaware County Homes – located 1 mile apart | Home B – 19010 (856 Martin Ave) |
| $699,000 | Listing/Purchase price | $710,000 |
| Radnor Township | Municipality | Haverford Township |
| Radnor Township | School district | Haverford Township |
| $8,359 (2025) | MLS-reported property taxes | $11,746 (2025) |
| Monthly difference | $282/month more |
The takeaway: never assume two homes in "the same town" carry the same tax rate. The township and school district, not the mailing address, determine the bill.
LOCAL TAKE
We see this play out in real transactions all the time. I had a client comparing two $500,000 houses, one in Wynnewood and one in Havertown, similarly priced but in different neighborhoods. The Havertown house didn't end up qualifying for their loan, the Wynnewood house did. The reason was taxes: almost double in Havertown, a roughly $10,000 bill versus $5,600 in Wynnewood. That's close to $400 a month, and when your debt-to-income ratio is already tight, that $400 a month is the difference between a house that works for your mortgage and one that doesn't.
How to Look Up the Actual Taxes on a PA Property
The estimates above are planning tools, not a substitute for checking a specific address. Before you make an offer, confirm the property's exact municipality and school district (your agent, a title company, or the county assessment office can confirm this), then check the current assessed value and combined millage rate for that specific jurisdiction. In most counties, property assessment and tax information is a matter of public record and can be looked up online.
LOCAL TAKE
We check taxes closely the moment a client falls in love with a home, we want them to understand the full cash out of pocket and the monthly payment for that specific property. But by then it's often late in the process. At the very least, we want buyers to understand the tax impact before they go under contract, and to confirm it works with their lender.
Ideally, though, we're having this conversation from the very beginning, so buyers know upfront that different areas carry different tax structures, and they're looking at a home's price and its annual taxes together, not the price alone.
Once buyers understand how taxes affect affordability and their debt-to-income ratio, they start factoring it into their search on their own, sometimes that means a $380,000 home in the city is realistic where a $295,000 home in Delaware County isn't, purely because of the tax difference.
As for where clients actually find the numbers, most of the time it's right on the Zillow listing, scroll down past the photos and it's there, or it's included in the documentation their agent sends them.
Should You Choose a Lower-Tax Area?
Not automatically. A lower property tax rate is one input into total housing cost, not the whole picture. Areas with lower effective rates sometimes carry higher home prices, or school districts that matter less to your specific priorities.
A few hundred dollars a month in tax savings can come with tradeoffs like a longer commute or a home that needs more work. The right question isn't "which area has the lowest tax rate," it's "which area gets me the total package: price, taxes, schools, and location that fits what I actually need."
LOCAL TAKE
There's a real logic behind which areas run higher or lower on taxes, but it's not always what people expect. In my experience, a lot of this comes down to a municipality's needs, areas with a higher share of renters often have less tax capacity elsewhere, so more of the burden falls on homeowners. But that doesn't always track with school quality. Wynnewood is a good example: it's in Lower Merion School District, one of Pennsylvania's highest-ranked school districts, and it has lower taxes than Havertown, which is a strong district in its own right, just not ranked as high as Lower Merion. You'll see the same pattern in some of the more affluent, outlying areas too, bigger homes, lower taxes than you'd expect.
Most of our buyers aren't picking a location purely because of the tax rate. They're picking based on school district, proximity to family or work, and quality of life, and taxes only become the deciding factor when someone is already price-bound and simply can't make a higher-tax area work for their budget. Either way, our job is to make sure they understand the impact taxes have on their finances and their mortgage before they fall in love with a house they can't actually afford.
Which Philadelphia Suburbs Have the Lowest Property Taxes?
If keeping property taxes lower is a priority, Chester County had the lowest typical effective rate among the four suburban counties we analyzed, though rates still vary significantly by municipality and school district.
If the school district is driving your search, pay especially close attention in Delaware and Montgomery Counties, where our analysis found the widest ranges between the lowest and highest effective rates. Bucks County is worth a second look for buyers who get scared off by its high millage numbers. Because of the county's assessment ratio, its effective rates on market value are much closer to the other counties than the raw millage figures suggest.
LOCAL TAKE
Honestly, I don't know that I've ever had a buyer ask which suburbs have the lowest property taxes. Most buyers don't zero in on taxes until they understand the impact, and once they do, some areas end up ruled out because the tax bill makes the house they want unaffordable.
A good agent is constantly listening to what a client actually needs and adjusting the search accordingly. Some buyers tell us upfront they don't want taxes above a certain number, or that they need to hit a specific payment, and in those cases, high-tax areas just aren't the right fit. It's not only about finding the house with the deep closet and the finished basement, it's about protecting a client's money too. That's the other half of the job.
Getting a Clear Picture on Your Specific Search
Comparing effective tax rates across Philadelphia, Delaware, Chester, Montgomery, and Bucks Counties gets you close, but the real number always comes down to the specific address, township, and school district.
Now you understand why effective rate, municipality, and school district matter more than raw millage.
If you're comparing two homes and aren't sure what the tax numbers mean for your actual monthly cost, that's something we help buyers work through every day. Talk with Premier Home Team about your home search.
