Stone Harbor is reassessing every taxable property in the borough, and the valuation date was October 1, 2026, three days ago. If you're under contract this fall, or about to be, the annual tax figure on the listing comes from assessments last reset in 2018. The first bill based on the new values will be for the 2027 tax year.
The reassessment is designed to leave the total tax the borough collects unchanged. It changes how that total is divided among properties. What matters for any one house is how its value has moved since 2018 compared with the rest of town. Two homes listed at the same price can have very different tax lines today, and the gap between them is exactly what the reassessment is meant to close.
How Far Assessments Have Drifted
New Jersey's 2026 Chapter 123 average ratio for Stone Harbor is 50.22%. That means assessments across the borough average about half of true market value. In 2025, Cape May County's final equalization table put the ratio at 53.30%, so the gap grew by about three points in a single year. When the ratio falls like that, market values are rising faster than the assessment rolls are keeping up.
The county's 2026 table shows how wide the gap has become. Stone Harbor's real property carries $5,133,797,900 in taxable assessed value against an aggregate true value of $10,222,616,288. The 2018 Abstract of Ratables listed $4,828,103,400 in net taxable value. So the assessed base grew about 6% over those eight years, while the state's own estimate puts market value at roughly double the assessed figure.
The 50.22% is a townwide average, and it hides a lot of variation. The borough's November 2025 overview said the reassessment would recognize "additions, renovations and other property improvements since the last reassessment in 2018." It also said the goal was for "improved properties" to "contribute their proportional tax obligations." In plain terms, some homes are carried well below the average ratio and others sit closer to it. A listing's tax line doesn't show which kind of home you're looking at.
Two Houses at the Same Price
The 2026 total general tax rate in Stone Harbor is $0.799 per $100 of assessed value, which works out to an effective rate of 0.401% of market value. The example below applies that 2026 rate to two hypothetical homes, each worth $3 million today. It shows how the current system works. It is not a forecast of anyone's 2027 bill.
| Hypothetical home | Market value | 2026 assessment | Share of market value | 2026 general tax at $0.799 |
|---|---|---|---|---|
| Home A, assessed near the town average | $3,000,000 | $1,500,000 | 50% | about $11,985 |
| Home B, assessment lagging its current value | $3,000,000 | $1,050,000 | 35% | about $8,390 |
Both homes are worth the same, but Home B's tax line is about $3,600 lower. A buyer comparing the two listings might read that as a lower carrying cost. Under the 2018 assessments it is. The reassessment exists to bring Home B's assessment in line with its market value.
Once the new values are in, both homes will be assessed close to the same figure, and the tax rate will be recalculated against the new, much larger base. The borough says some properties' tax burden "will increase to reflect improvements, while others will stay the same or decrease." Cape May Current's September 20, 2026 analysis says it the same way: a home that appreciated about as fast as its neighbors should see little change in its actual bill, even if its assessed value rises sharply on paper.
Applied to a purchase, the question isn't whether a home's taxes will go up in 2027. The question is whether this home has gained more value since 2018 than the typical Stone Harbor property. A home that was rebuilt, expanded, or heavily renovated after 2018 is the kind the borough itself says it wants to capture.
A Lower Rate Next Year Won't Answer the Question
When the new values take effect, the posted tax rate will very likely drop, because the same levy will be spread over a much larger assessed base. A lower rate can look like a tax cut. Avalon's 2018 reassessment, the nearest local example, shows why that reading doesn't hold up.
Avalon's reassessment report shows its ratable base growing from $7,499,656,900 to $8,933,539,000. Its general tax rate fell from $0.556 in 2017 to $0.488 in 2018. Over the same period, the effective rate went from 0.505% to 0.514%. The posted rate dropped by about 12%, but the share of market value going to property tax went up slightly.
Avalon's process also shows how many owners questioned their new numbers. Of 5,659 owners, 362, or 6.39%, asked for an informal review. The report covers aggregate results only, so it can't show how any one Avalon household made out. What it does show is that a falling rate tells you nothing about a specific bill until you multiply it by that property's new assessment.
The Budget Is a Separate Change
A second change is happening alongside the reassessment, and the two are easy to confuse. Stone Harbor's 2026 municipal budget raised the local-purpose tax rate from $0.3355 to $0.3500 per $100 of assessed value. The Cape May County Herald reported in May 2026 that this comes to about $218 more a year in municipal taxes on a $1.5 million property.
The budget sets the total amount to be collected. The reassessment decides how that total is split among properties. Under the state's description, the general rate is the amount to be raised divided by the taxable assessed base. Council has already signaled pressure on the budget side. At the September 1, 2026 meeting, Councilmember Ken Biddick pointed to rising health insurance costs for municipal employees, which could add about $500,000 in spending, along with a Public Works contract still being negotiated and water and sewer infrastructure that will need replacing over the next 15 years. He said the borough is looking at parking and beach fees as ways to avoid or reduce a tax increase. Your 2027 bill will depend on both your new assessment and the 2027 budget, and the reassessment controls only one of them.
Council President Jennifer Gensemer described the borough's goal in September 2025:
"Assessments are meant to reflect the current market value of each property, so that every property owner contributes their appropriate share toward municipal services and operations."
The Calendar for a Fall Contract
These dates matter most for anyone buying in Stone Harbor between now and spring:
- November 3, 2025. Council authorized a $675,000 emergency appropriation for the reassessment, with the cost spread over five years.
- June 15, 2026. Professional Property Appraisers began interior and exterior field inspections.
- September 1, 2026. Councilmember Biddick reported the work was about 70% to 75% complete.
- October 1, 2026. The valuation date. Every property is valued as of this day.
- Late 2026 or early 2027. Notices of proposed values are mailed, and owners can discuss them with PPA and submit documentation.
- Spring 2027. Cape May County's appeal brochure gives May 1 as the deadline in a year when a reassessment was completed. The county's general appeal FAQ lists April 1, so confirm the 2027 deadline with the County Board of Taxation or the borough before relying on either date.
If you close in the next few months, you may own the home when the proposed-value notice arrives. You would then be the one reviewing it with PPA, even though the valuation date fell before you owned the property.
What to Ask Before You Sign
The interior inspection is the piece most likely to come up in a transaction. Councilmember Biddick said an inspection takes less than five minutes and covers rooms, bathrooms, fireplaces, and how much an older home has been "refreshed." He warned that without an interior look, assessors could assume a value higher than the home's actual value. On September 23, the borough confirmed that PPA's second interior-inspection letter is official and asked owners who still hadn't been inspected to cooperate.
Questions worth putting to the seller this fall:
- Did PPA inspect the interior, or only the exterior?
- What work has been done on the house since 2018, and was it permitted?
- Has the seller received a proposed-value notice, or will it arrive after closing?
- How does the home's 2026 assessment compare with its sale price? The town average is about 50%.
None of these answers will tell you the exact 2027 bill, and nobody can give you that number yet. They will tell you whether the current tax line is likely to hold up once the new values take effect.
A Few Questions I Get About This
Will the reassessment raise Stone Harbor's taxes overall? The borough says a reassessment does not automatically increase municipal property taxes, because spending still determines the total levy. Budget increases like the 2026 one are decided separately.
Who do I call about the process? Professional Property Appraisers takes questions at 1-866-957-1388. The borough assessor is Margaret G. Slavin, CTA.
I'm looking at a bayfront home. Is there anything else on the borough calendar? Yes. Ordinance 1706, adopted May 5, 2026, keeps a December 31, 2026 deadline: bulkheads that were at 5.5 feet NAVD 1988 or lower in 2018 must be raised to at least 6.2 feet. The ordinance also sets $1,500 in borough permit and engineering-review fees for bulkhead work, before private engineering costs.
