Two listings, same asking price, thirty minutes apart on the map. One sits in Pitman, the walkable little borough with the wraparound porches and the Broadway strip everyone loves. The other sits in South Harrison, out where the lots run wide and the pace slows down. A buyer scrolling both on a Saturday morning sees the same number in bold at the top of each listing and reasonably assumes the monthly cost of owning either home lands in the same neighborhood too.
It doesn't. Not close.
Gloucester County's town-by-town property tax rates are public record, and when you line them up next to each other, the story they tell runs against the assumption most buyers walk in with. A lower list price does not guarantee a lower carrying cost. In some cases it means the opposite.
The Rate on the Portal Isn't the Rate That Matters
Every New Jersey town publishes a general tax rate, the number your assessor multiplies against your home's locally assessed value to produce your bill. The problem is that assessed values drift out of sync with real market value between town-wide reassessments, sometimes by a lot, so a general rate in one town isn't directly comparable to a general rate in the next town over.
New Jersey solves this with a second figure.
The effective tax rate adjusts every municipality's assessments to 100% of true market value, so it's the number that actually lets you compare one town's tax burden to another's. It's not what shows up on your bill, but it's what tells you the truth about relative cost.
That distinction matters here because Gloucester County's towns don't reassess on the same schedule, and a general rate alone can flatter a town that's simply overdue for a revaluation.
What a $450,000 Home Actually Costs, Town by Town
Using the certified 2025 general and effective tax rates published by the New Jersey Division of Taxation, the most recent full-year rate table the state has finalized and released, here's what a $450,000 home carries in estimated annual property tax across towns the Pat Settar Team works in most often. This is a simplified estimate based on the effective rate alone. It doesn't account for exemptions, added assessments, or fire district charges that some towns layer on separately, so treat it as a comparison tool rather than a bill.
| Town | General Rate | Effective Rate | Est. Monthly Tax on $450,000 |
|---|---|---|---|
| South Harrison Township | 3.306 | 2.049% | $768 |
| Harrison Township (Mullica Hill) | 3.300 | 2.138% | $802 |
| East Greenwich Township (Mickleton, Mount Royal) | 3.187 | 2.141% | $803 |
| West Deptford Township | 3.483 | 2.279% | $855 |
| Mantua Township | 2.516 | 2.287% | $858 |
| Swedesboro Borough | 4.358 | 2.672% | $1,002 |
| Pitman Borough | 3.596 | 2.817% | $1,056 |
Look at the ends of that table. South Harrison, the township most associated with larger lots and higher price points in this group, carries the lowest effective rate on the list. Pitman, the walkable borough where entry-level buyers often start their search because of its smaller homes and lower average price, carries the highest.
On identical $450,000 purchases, that's a gap of roughly $288 a month between the two towns, close to $3,450 a year, driven entirely by which side of a township line the deed sits on. A buyer who chose the "cheaper" town on price alone could end up paying more every month than the neighbor who bought the pricier house down the road in South Harrison.
None of this means Pitman is a bad buy. Its tax rate reflects a smaller, older municipal footprint with less room to spread school and county costs across new ratables. It means the sticker price on a listing tells you almost nothing about what you'll actually carry each month until you check the town's effective rate against it.
Why Woolwich Is Worth Watching Separately
Woolwich Township doesn't fit neatly into that table because its rate has been moving. In 2023 its effective rate stood at 2.774%. By 2024 it had dropped to 2.522%. As of this summer, the township has confirmed its official 2026 rate is in hand, and the direction of travel matters more than any single year's number: Woolwich has been adding new construction across multiple planned communities for years now, and every new home added to the tax base gives the township more ratables to spread its budget across. That tends to ease the effective rate over time, even when nothing about the underlying budget changes.
A buyer comparing Woolwich to a fully built-out neighbor should expect that trend to continue as more phases come online, not necessarily hold steady.
The Swedesboro Wrinkle
Swedesboro's 2.672% effective rate, the second highest in the table above, comes with a timing note worth knowing if you're shopping there this year. The borough is currently undergoing a property tax reassessment, and physical inspections are already complete. Residents will receive a preliminary assessment notice for the 2027 tax year before November 2026.
A reassessment resets every property's assessed value to reflect current market value, which changes the general rate the following year even when the effective rate, the true comparative measure, tends to hold closer to the level it should have been at all along. If you're closing on a Swedesboro home this year, budget against the current effective rate, but know that your actual bill in 2027 will be calculated off a freshly updated assessment rather than whatever number is currently on the seller's most recent statement.
The Calendar Quirk That Catches Buyers Off Guard
Most of New Jersey gives homeowners until April 1 to formally appeal a property tax assessment. Gloucester County doesn't. Along with Burlington and Monmouth counties, it runs on an earlier calendar entirely:
- Assessment postcards go out to property owners on or before November 15.
- The formal appeal window opens the same day, November 15.
- Appeals, filed online through the state's appeal portal or in person at the Board of Taxation in Clayton, must be received by 4:00 PM on January 15.
Miss that window and you're locked into the year's assessment regardless of what the home is actually worth. Buyers who close in late fall should ask their agent or attorney about the current assessment right away rather than assuming they'll have until spring to review it, the way they might in most other New Jersey counties.
There's a second-order effect here too. When enough owners in a town successfully appeal and their assessed values drop, the town's total ratable base shrinks. If the municipal budget stays flat, the rate applied against everyone else has to rise slightly the following year to make up the difference. It's a quiet feedback loop that can nudge a town's general rate upward even in years when spending doesn't grow at all, and it's part of why the effective rate, not the headline number, is the one worth comparing across towns.
What This Means If You're Comparing Towns Right Now
If you're cross-shopping Gloucester County towns this season, run the effective rate against any price you're seriously considering before you fall in love with a floor plan. A $420,000 home in Pitman and a $460,000 home in South Harrison might land within a few dollars of each other every month once taxes are factored in. That's the comparison that actually predicts your monthly payment, not the number at the top of the listing.
Frequently Asked Questions
Does a lower general tax rate always mean a lower bill? Not on its own. The general rate is multiplied against your town's locally assessed value, which may or may not reflect current market value. Two towns with similar general rates can produce very different bills if one town's assessments are years out of date. The effective rate strips that variable out and is the better tool for comparing towns.
What happens if I miss the January 15 appeal deadline in Gloucester County? You're locked into that year's assessment. There's no late-filing exception for a missed deadline the way some other tax processes allow. The next opportunity comes with the following year's assessment postcard in November.
Will my tax bill change if my town gets reassessed after I buy? Likely yes, though not always in the direction you'd expect. A reassessment updates every property's assessed value to reflect current market conditions. If your home's value grew in line with the town average, your bill may hardly move even though the number on paper looks different. If it grew faster than the town average, expect an increase.
Property tax comparisons like this one are exactly the kind of detail that gets lost between one portal search and the next, and it's the kind of thing worth walking through with someone who tracks these towns closely before you commit to one over another.
