Pennsylvania Property Tax Calculator (Assessed Value & Millage Rates)

Ranked #14 out of 50 states at an average effective rate of 1.16%, Pennsylvania lands above the national median. That is modestly above the national average of roughly 1.0%, based on the average effective rate across all 50 states. Compared with the rest of the Northeast, which averages roughly 1.61%, Pennsylvania lands well below its neighbors.

As in most of the Northeast, property tax revenue in Pennsylvania funds local school districts, county services, and municipal budgets rather than flowing through a state-level general fund, so the rate is effectively set locally even though the average is reported statewide.

Assessments are handled at the county level in Pennsylvania, where local appraisers periodically revalue residential and commercial parcels and apply the applicable millage rates; homestead exemptions and formal appeals remain the main levers available to individual owners looking to manage the bill, alongside any local bond measures voters approve along the way.

Pennsylvania has no statewide reassessment requirement, and some counties still bill against base year values set decades ago. A common level ratio published each year translates those stale assessments back into current market terms, which is the only way to compare one county's rate to another's.

None of that detail is asked for here. This calculator works one level up, applying Pennsylvania's average effective property tax rate of 1.16% to the value you enter. That rate is the ratio of property taxes actually paid to home value across the state, so the assessment ratios, caps, and exemptions described above are already baked into it.

Working through it in order:

1. Start from the county's assessed value. It reflects the county's base year, which may be many years or many decades old.
2. Take off the homestead and farmstead exclusion. School districts fund it from gaming revenue, and the amount varies by district.
3. Multiply by the effective rate. At 1.16%, a $400,000 home in Pennsylvania comes to $4,640 a year before any exemption you enter above.
4. Divide by twelve for escrow. That same home works out to $386.67 a month set aside in a mortgage escrow account.
5. Compare it against your own bill. School district millage is the largest line on almost every Pennsylvania bill, and it is set district by district. Your county's number is the one that governs; this figure tells you whether it is roughly where a Pennsylvania home of that value ought to land.

Using this calculator's baseline inputs: a $400,000 home in Pennsylvania, taxed at the state's 1.16% average effective rate (rank #14 of 50 states).

1. Start with the assessed value. The home is assessed at its full $400,000.00 market value, with no homestead exemption applied in this baseline scenario.
2. Apply the effective rate. $400,000.00 × 1.16% = $4,640.00 in annual property tax, Pennsylvania's statewide average effective rate.
3. Convert to a monthly escrow. Lenders typically collect property tax in twelve equal installments alongside principal and interest: $4,640.00 ÷ 12 = $386.67 per month.
4. Project a five-year hold. At a flat rate, five years of ownership totals $4,640.00 × 5 = $23,200.00, before any reassessment, exemption change, or millage increase.

At 1.16%, Pennsylvania lands roughly in the middle nationally, ranking #14 of 50 states. That is a moderate but still material carrying cost for homeowners.

Pennsylvania's 1.16% is applied as a single statewide effective rate, so the twelve-row sweep rises in equal steps and the interesting material is in what that one rate is standing in for.

Ten thousand dollars of assessment, in dollars of tax. Raising the assessed value from $400,000 to $410,000 moves the annual tax from $4,640.00 to $4,756.00. Every additional $10,000 of Pennsylvania valuation costs exactly $116.00 a year, at every value the calculator accepts. Doubling the value to $800,000 doubles the tax to $9,280.00 to the cent.

What the twelve tiers show. The table steps the value in increments of $66,666.67, from $66,666.67 in row one to $800,000 in row twelve, and the tax column rises by exactly $773.33 on every row without a single break. Row six carries the $4,640.00 baseline; row twelve carries $9,280.00, which is precisely double it.

The inverse calculation. Divide by 0.0116. A $10,000 annual bill corresponds to $862,068.97 of assessed value, and the $400,000 baseline is the value that produces the $386.67 monthly escrow line. Because the relationship is exactly linear with no cap, no cliff and no minimum, there is no valuation at which the arithmetic bends.

What the exclusion field changes. Entering a $25,000 exemption reduces the taxable assessed value to $375,000 and the annual tax to $4,350.00, a saving of $290.00 a year against the $4,640.00 the page returns with the field at zero. That reduction reaches the headline, the monthly escrow figure and the twelve-row schedule alike. With $25,000 entered, row six prices $400,000 of value at $4,350.00, the same figure as the headline, and row one falls from $773.33 to $483.33. Because every row nets the same exemption off before applying the 1.16% rate, the table can be read straight across against the result above it rather than being treated as a separate gross-value answer.

Comparing the escrow line to the servicer's draw. The escrow figure is where the common error lives. The monthly line the engine reports is $386.67, being $4,640.00 divided by twelve. Lenders frequently collect a cushion of up to two months on top, so a servicer's actual monthly draw on this property can run above $386.67 without any of the tax figures on this page being wrong. Comparing a servicer's escrow line directly against $386.67 and concluding the assessment is wrong is the mistake this page most often provokes.

What the rate is standing in for. Pennsylvania's 1.16% is a statewide average of millage set separately by the county, the municipality and the school district, with the school district usually the largest of the three. The engine holds no millage table and performs no common level ratio conversion, though Pennsylvania counties assess at wildly different fractions of market value and some have not reassessed in decades. The Homestead and Farmstead exclusion funded by gaming revenue is not applied either.

• Specific hyper-local county and municipal millage district variations within Pennsylvania.
• Municipal authority and special assessment charges. Some Pennsylvania municipalities levy additional assessments through municipal authorities for sewer, water, or street improvements on top of the base county, municipal, and school millage; the specific list varies by municipality.
• Commercial vs residential assessment classification differentials.
• Property tax appeal reductions or localized board of equalization adjustments.

• Confusing Market Fair Value with Assessed Basis: Some jurisdictions assess property at fractional ratios rather than 100% of market value.
• Failing to File Homestead Paperwork: Homestead exemptions are rarely automatic; homeowners must file timely paperwork with the county appraisal district.
• Underestimating Post-Sale Supplemental Assessments: Purchasing a newly constructed or reassessed property often triggers catch-up supplemental tax bills.
• Ignoring Property Tax Appeal Windows: Missing the annual 30-to-60 day statutory protest window forfeits the right to challenge over-assessed property values for that tax year.
