How Much Are Property Taxes in Montgomery County, PA?

The short answer: property taxes in Montgomery County are set by your township, municipality, and school district, based on an assessed value that is decades behind current market values for many homes. There is no single countywide rate. Your annual tax bill is the sum of several millage rates multiplied against your property's assessed value, and those rates can differ dramatically between, say, Lower Merion and Lansdale.

In Pennsylvania, the tax bill is built from three layers: the county, the municipality or township, and the school district. Each one sets its own millage rate, and the school district portion is usually the largest slice of your total bill. A home in a township with a highly rated school district will generally carry a higher tax bill than an otherwise identical home in a district with lower spending, because the rates are simply higher.

The single most important thing to understand: the assessed value on your tax bill is not your market value, and it rarely changes with the market. Sales in Montgomery County are recorded at market prices while assessments often reflect values from years ago, which is why two similar homes can have very different effective tax rates.

Rates vary by town, and the variation is meaningful when you compare communities. North Penn, Wissahickon, Lower Merion, Colonial, Methacton, and the other districts in the county each set their own millage, so your tax bill depends as much on your school district as on your home's value.

In broad terms, Montgomery County homeowners commonly carry effective tax burdens somewhere in the range of 1.5% to 2.5% of a home's market value, with the actual percentage depending on the town and district. Conshohocken, Blue Bell, and Ambler buyers should each run the math for their specific district, because neighboring towns in the same county can differ by a full percentage point.

Pennsylvania reassesses on a countywide cycle, and Montgomery County has not done a full countywide reassessment in more than a decade. That means many assessments have drifted far from market value, and some homes are taxed on values that are a fraction of what they would sell for today.

A countywide reassessment revalues every property at the same point in time, usually with an effective date and a new assessment ratio. When a county does reassess, some bills go up and some go down, because the new base reflects actual market conditions. The alternative approach, used in some states, is a base-year system, which Pennsylvania counties do not generally use.

In most Pennsylvania counties, a sale itself does not trigger an automatic reassessment to market value, and tax assessments are typically not set at a sale price. What does change your bill is a reassessment cycle, a successful appeal, or a change like a new building permit. If you believe your assessment is out of line with neighboring homes, every county has an appeal window each year, and the first step is comparing your assessment to your neighbors'.

Keep the big picture in mind: Montgomery County's tax structure rewards long-term ownership, because a low assessment means a relatively stable bill, while new construction and new buyers often pick up a larger share of the county's tax base.

Exemptions and relief programs can lower your effective tax burden, but they vary by municipality. Pennsylvania law allows counties and municipalities to adopt a homestead exemption, which reduces the assessed value of your primary residence and thereby your tax bill. Not every municipality in Montgomery County has adopted one, so check with your township.

Several other programs can help homeowners specifically:

• ✓ Senior Citizen Real Estate Tax Relief (SCERP): Income-qualified seniors may receive a reduction on the county portion of their tax bill.
• ✓ Property Tax and Rent Rebate: A state program that rebates a portion of property taxes or rent paid by qualifying older homeowners and renters.
• ✓ Homestead Exclusion: Where adopted, it shields a portion of assessed value from taxation on your primary residence.
• ✓ Veterans and disabled programs: Pennsylvania offers property tax relief for qualifying veterans and disabled homeowners.

Because these programs are income-based and change with state budgets, verify current eligibility with your township or the county's tax office before you count on them.
