Two homes in the Collegeville area are listed at the same price. Why would one cost about $1,500 more a year to own?
The municipality the parcel sits in decides the bill. Collegeville Borough, Trappe, Skippack, Lower Providence and Upper Providence each add their own municipal levy on top of a school district rate. Montgomery County's 2026 schedule puts their total millage anywhere from 44.084 to 54.552, depending on which side of a line the house sits.
The bill a buyer takes over
In Montgomery County, property tax comes in pieces on different dates. In all five of these municipalities, the 2026 municipal bills are dated in March and the 2026–27 school bills are dated July 1, 2026. The county rate is the same everywhere, 5.462 mills, and so is the Montgomery County Community College rate of 0.49 mills. The differences all come from the last two columns, the municipality and the school district.
The transfer tax that comes due at closing is easier to predict. Collegeville Borough's tax page lists a 2% realty transfer tax split three ways: 1% to Pennsylvania, 0.5% to the borough and 0.5% to the Perkiomen Valley School District. The page says buyer and seller customarily pay 1% each. Lower Providence lists a 1% local transfer tax split between the township and Methacton. Add Pennsylvania's 1% state tax and the total is also 2%. The one-time cost at closing barely changes between these two. The yearly bill afterward does.
Five municipalities, one area
Mills turn into dollars with simple arithmetic: assessed value times millage, divided by 1,000. Collegeville Borough publishes that formula on its tax page. The table below shows the 2026 rates from the Montgomery County millage schedule for each municipality, applied to the same example assessment of $148,810. That's roughly what a $500,000 sale price works out to when you divide it by the state's current Montgomery County factor, which is explained further down.
| Municipality | 2026 municipal mills | 2026–27 school mills | Total mills | Example bill at $148,810 assessed |
|---|---|---|---|---|
| Collegeville Borough | 8.55 | 40.05 | 54.552 | about $8,118 |
| Trappe | 1.97 | 40.05 | 47.972 | about $7,139 |
| Lower Providence | 4.2534 | 37.6116 | 47.817 | about $7,116 |
| Skippack | 0.8616 | 40.05 | 46.8636 | about $6,974 |
| Upper Providence | 2.75 | 35.382 | 44.084 | about $6,560 |
These figures only illustrate the math. They aren't quotes for any real property, and a homestead exclusion would lower the school portion for an owner-occupant who qualifies. They still show how the rates are put together. Collegeville Borough, Trappe and Skippack pay the same school rate. The borough's higher total comes almost entirely from its municipal line, which is more than four times Trappe's. Upper Providence ends up lowest even though its municipal rate is higher than Trappe's or Skippack's, because its school rate is the lowest of the group.
So the gap comes from two separate sources, and each one deserves its own explanation.
What 8.55 mills pays for inside the borough
Collegeville Borough runs its own police department, and its budget shows the cost. The adopted 2026 budget puts $2,323,893 toward public safety, the largest category, ahead of $954,600 for roads and $490,201 for sanitation. The borough's tax page splits the 8.55 mills into 7.2 for general purposes, 1.0 for fire services and 0.35 for ambulance service.
The rate went up for 2026. The Borough Council minutes from November 17, 2025 show a draft budget that had been about $500,000 short before cuts, leaving a remaining gap of roughly $225,000. That gap came from two contracts. Trash service was rising $20,000 to $25,000 a year through 2027, and police costs were up about 10% for salaries and benefits. Council proposed a 1-mill increase, estimated to raise about $260,000, bringing the borough to 8.55 mills. Council voted 6–0 to advertise that budget.
The same minutes give some context. The borough manager noted that Montgomery County boroughs with their own police departments average 9.75 mills, so Collegeville's 8.55 is below that group's average. The 2026 budget also included Green Light Go traffic signal upgrades, Bum Hollow Trail work funded partly through Montco 2040, and $360,000 in road work. On the example assessment above, the 1-mill increase adds about $149 a year.
The sources we reviewed don't say how Trappe, Skippack or the two townships fund public safety. The lower municipal rates there are a fact in the county schedule, but this post doesn't try to explain them.
The school line moved in every district this year
The municipal gap has a clear explanation inside the borough. The school gap changes every June, and all three districts serving these five municipalities raised their rates for 2026–27.
- Perkiomen Valley School District, covering Collegeville Borough, Trappe and Skippack. The district's business page lists 38.70 mills for 2025–26, and the county lists 40.05 mills for 2026–27. That works out to an increase of about 3.5%.
- Methacton, whose 2026–27 rate of 37.6116 mills matches Lower Providence's school line on the county schedule. The rate rose from 35.7219 mills. The district's final budget report lists a $10,483 assessed-value homestead exclusion. Perk Valley Now reported that the board approved the budget 8–0 at a June 16 special meeting. It described a 5.29% increase driven by special education costs, estimated at $333.76 a year for a median-assessed homestead.
- Spring-Ford Area, whose 2026–27 rate of 35.382 mills matches Upper Providence's school line. Its final budget report shows the rate rising from 34.1855 mills, an increase of about 3.5%, with a $9,327 assessed-value homestead exclusion.
The homestead exclusions make the gap a bit smaller for owner-occupants. Applied at each district's own rate, Methacton's exclusion is worth about $394 and Spring-Ford's about $330. The research didn't turn up a published 2026–27 exclusion figure for Perkiomen Valley. Until that figure is confirmed, a buyer comparing a borough home with a Lower Providence home can't line up the after-exclusion bills exactly.
Why an old assessment makes the gap matter more
Montgomery County hasn't had a countywide reassessment since 1998, according to Collegeville Borough's tax page. Assessments still reflect market value as of that reassessment, and the county publishes a factor each year for estimating today's value from them. The Pennsylvania Department of Revenue's July 2026 factor list gives Montgomery County a factor of 3.36. It is based on 2024 sales data and applies to documents accepted from July 1, 2026 through June 30, 2027.
That's where the $148,810 example assessment comes from: $500,000 divided by 3.36. Individual assessments can sit well above or below that ratio. A house assessed in 1998 and a similar house built since can carry very different assessed values even if they would sell for about the same price today. So the millage table is only half the comparison. A low-millage parcel with a relatively high assessment can cost more than a high-millage parcel with a low one.
The property's actual assessed value and the municipality it sits in are both public. Together they predict the bill much better than the town name on a listing or the listing's tax estimate.
Questions to settle before an offer
- Which municipality is the parcel actually in? The county assessment record names it.
- What is the parcel's current assessed value? Multiply it by that municipality's total 2026 millage and divide by 1,000.
- Does a homestead exclusion apply, and how much is it in that school district for 2026–27?
- How will the March municipal bill and the July school bill be prorated at settlement?
- If the home is in the borough, what's ahead on the local calendar? Main Street District zoning was still under consideration as of the borough's June 2026 ordinance listing. PennDOT proposes rehabilitating the Ridge Pike bridge over the Perkiomen Creek, between the borough and Lower Providence, from April 2027 to July 2028, with traffic kept moving in both directions.
FAQ
Is the transfer tax higher in Collegeville Borough? The sources we checked list a 2% total for both Collegeville Borough and Lower Providence, with half going to Pennsylvania. The difference between these areas shows up in the yearly bill, not at closing.
Why is Upper Providence's total the lowest of the five? Its 2026–27 school rate of 35.382 mills is the lowest in the group, which brings its total down to 44.084 mills even though its municipal rate is above Trappe's and Skippack's.
Can the tax rate change after I buy? Yes. Collegeville Borough added 1 mill for 2026, and all three school districts raised their rates for 2026–27. Budgets are voted on each year, so these rates describe 2026 and the 2026–27 school year only.
