Property Tax Rates in Montgomery, Delaware, and Bucks Counties: What First-Time Buyers Need to Know

The Philadelphia suburbs are one of the primary escape routes for buyers priced out of the city — or for buyers who want top-tier public school districts and more living space. What they don't always anticipate is that the trade-off involves some of the highest property taxes in Pennsylvania.

The Main Line in Montgomery County, the school districts of Delaware County, and the suburban communities of Bucks County all carry substantial annual property tax burdens. For a buyer moving from Philadelphia, the savings from a lower transfer tax and no wage tax can evaporate quickly once the property tax bill arrives. For a buyer coming from out of state, the absolute numbers may come as a genuine shock.

Here's how the three collar counties compare and what determines your actual bill.

How Pennsylvania Property Taxes Work in These Counties

Before comparing rates across counties, it's essential to understand the structure. Pennsylvania homeowners pay three separate property taxes:

1. County tax — levied by Montgomery, Delaware, or Bucks County separately
2. Municipal tax — levied by your specific township or borough (Upper Merion Township and Lower Merion Township are different municipalities even though they sound similar)
3. School district tax — by far the largest of the three, typically representing 60% to 70% of total property tax obligation

Each entity sets its own millage rate. One mill equals $1 of tax per $1,000 of assessed value. Your total combined millage rate is the sum of the county, municipal, and school district rates.

What makes this genuinely complex is that assessed values in Pennsylvania are not always equal to market value. Each county conducts reassessments at different intervals, and the relationship between assessed value and market value (the "common level ratio") varies by county and changes over time. Your lender's escrow estimate is based on current tax bills, which may not reflect a recent purchase price.

Montgomery County Property Tax Rates

Montgomery County is home to some of the most expensive real estate — and highest property taxes — in Pennsylvania. The county includes the prestigious Main Line communities (Lower Merion, Radnor in adjacent Delaware County, Haverford), along with Conshohocken, Blue Bell, Lansdale, Horsham, and dozens of other townships and boroughs.

The county millage rate itself is relatively modest. The variable that drives bill totals is the school district rate.

In Lower Merion Township, which encompasses communities like Ardmore, Haverford, Bryn Mawr, and Merion — among the most sought-after Philadelphia suburbs — the combined millage rate (county + municipal + school district) runs in the range of 30 to 35 mills. On a home assessed at $350,000, that produces an annual tax bill of approximately $10,500 to $12,250.

In less expensive Montgomery County municipalities — townships like Limerick, Pottstown, or Horsham — the school district millage rates are lower, producing combined rates of 20 to 25 mills. The annual bill on a $300,000 assessed home falls in the range of $6,000 to $7,500.

School district quality largely determines millage rates in Montgomery County. The top-ranked districts (Lower Merion, Upper Dublin, Wissahickon) carry the highest rates because they're also the most desirable, producing a self-reinforcing cycle of high home values and high tax rates.

For PHFA program purposes, Montgomery County falls into the higher-income limit region (1-2 member household income limit approximately $95,520), reflecting the county's higher income profile.

Delaware County Property Tax Rates

Delaware County's municipalities range from the high-value Main Line communities of Radnor, Haverford, and Marple townships to more affordable communities in Chester, Darby, and Upper Darby.

Radnor Township, which includes Wayne and St. Davids, has combined millage rates in the range of 22 to 27 mills. The Radnor School District is consistently ranked among the top in the state, and the tax burden reflects that. On a $400,000 assessed home in Radnor, annual taxes run approximately $8,800 to $10,800.

Springfield Township and Marple Newtown Township, popular with buyers seeking good schools at a slightly lower price point than the innermost Main Line communities, carry combined rates of 20 to 25 mills.

Upper Darby and Clifton Heights, at the more affordable end of Delaware County's spectrum, have lower home values but school district millage rates that make the effective tax burden significant relative to assessed value — often producing higher effective tax rates (taxes as a percentage of market value) than wealthier districts.

Delaware County also includes Swarthmore Borough, with high property values driven by the presence of Swarthmore College, and Media Borough, the county seat, which combines walkable downtown amenities with higher combined rates.

One important Delaware County characteristic: the county last conducted a county-wide reassessment in 2000. This means assessed values may diverge significantly from market values in areas that have appreciated. Buyers should verify the common level ratio for Delaware County to understand the relationship between their purchase price and their likely assessed value for tax purposes.

Bucks County Property Tax Rates

Bucks County stretches from the Philadelphia border in the south (Bristol, Bensalem, Levittown) to rural areas in the north approaching the Pocono region. This geographic span produces enormous variation in property tax rates.

In the southern municipalities closest to Philadelphia — Bensalem Township, Bristol Township, and Lower Southampton — combined millage rates tend to be in the range of 18 to 24 mills. These are more affordable markets with moderate school district performance.

Moving into central Bucks County — Newtown Township, Doylestown Borough, Buckingham Township — the market becomes more premium. The Central Bucks School District, one of the largest and most highly regarded in the state, carries higher millage rates. Combined rates in this area typically run 22 to 28 mills. On a $450,000 assessed home, annual taxes might run $9,900 to $12,600.

Upper Bucks County municipalities like Quakertown and Perkasie have lower home values and more modest combined millage rates — often in the 20 to 22 mill range — though the school district performance profile is more variable.

Bucks County benefits from strong historical character (New Hope, Doylestown) and proximity to New Jersey via bridges. The county has experienced significant demand from buyers relocating from New Jersey, which has driven prices higher in the most accessible communities.

The Fiscal-Year School Tax Proration Trap

Montgomery, Delaware, and Bucks County school districts (with the exception of a few specific districts) bill on a fiscal year — July 1 to June 30. County and municipal taxes bill on the calendar year.

This creates a significant closing cost complication that catches buyers off guard. If you close on September 1:

• County and municipal taxes: the seller has paid through December 31. You owe the seller reimbursement for October, November, and December (3 months of combined county + municipal taxes).
• School district taxes: the seller has paid for the full July 1 to June 30 fiscal year — which means they've pre-paid school taxes through the following June 30. You owe the seller reimbursement for your occupancy period of September 1 through June 30 — 10 months of the school year.

School taxes on a $400,000 home in a high-millage Montgomery County township might run $7,000 to $9,000 per year. Reimbursing the seller for 10 months of that bill adds $5,833 to $7,500 to your closing costs — on top of the transfer tax, title insurance, and all other expenses.

This is not a mistake or a rip-off; it's the standard proration mechanic that ensures sellers are made whole for taxes they've prepaid. But buyers who budget for closing costs using national averages are not prepared for this line item. It's one of the primary reasons Pennsylvania buyers consistently need more cash at closing than generic calculators suggest.

Closing in late October through December minimizes this proration — less school year remaining means less proration owed to the seller. Ask your buyer's agent to model the proration impact of different closing dates if you have flexibility on timing.

The Homestead Exclusion in the Collar Counties

All three collar counties participate in the Pennsylvania Homestead Exclusion program. Once you establish the property as your primary residence, file the exclusion with the county assessor before March 1 to reduce your school district assessed value by the approved exclusion amount.

The exclusion amount varies by school district based on the gaming revenue distribution from the Property Tax Relief Fund. In high-value suburban districts, the exclusion amount per home is often relatively modest (the gaming revenue is spread across high-assessed-value properties). In some districts, the exclusion might be $5,000 to $10,000 off assessed value. In other districts with lower aggregate value and higher gaming revenue allocation, it may be $15,000 to $25,000.

Savings of $100 to $400 per year are common in collar county markets. It's not transformative, but it compounds over ownership.

Comparing Total Tax Burden: City vs. Suburbs

A buyer moving from Philadelphia to suburban Montgomery or Bucks County faces a common scenario: trading the city's 3.74% wage tax for substantially higher property taxes.

On $100,000 annual income:

• Philadelphia wage tax: $3,740 per year
• Typical suburban EIT: $1,000 to $2,000 per year

Net annual savings by leaving Philadelphia: $1,740 to $2,740 per year.

But if the suburban property tax is $9,000 versus a Philadelphia property tax of $5,600 on comparable homes:

• Additional suburban property tax: $3,400 per year

The net result: you might actually pay more in total annual taxes in the suburbs than in the city, even after escaping the wage tax. The specific numbers depend entirely on which municipality you're buying in and what home price you're targeting.

This calculation doesn't mean staying in Philadelphia is always better — school districts, space, and quality of life enter the equation. But buyers who move to the suburbs expecting meaningful tax relief are sometimes surprised when the math works out to rough parity.
