Kennilworth, NJ
Kenilworth's general tax rate is $6.625 per hundred dollars of assessed value. Multiply that by a $602,000 purchase price and you get thirty-nine thousand dollars a year, which would make this the most heavily taxed borough in New Jersey. The actual median bill is about eleven thousand four hundred. Understanding why is the single most useful thing a Kenilworth buyer can know.
Kenilworth's assessments sit far below market value — a median assessment of $172,700 against a median sale price near $602,000. That is why the general rate looks so high: a high rate applied to a low base. The number that actually compares towns is the effective rate of 2.002%, which sits below the Union County median of 2.113% and has fallen from 2.64% in 2015. Never multiply the general rate by your purchase price. Use the effective rate for comparison, and the actual current bill on the actual parcel for anything that matters.
Property tax figures are point-in-time and every parcel is different. Nothing here is tax or legal advice. Verify the actual current bill and assessment for any specific property with the Borough of Kenilworth Tax Assessor, and consult your own professionals before relying on any figure below.
New Jersey publishes two different property tax rates for every municipality, and they are not interchangeable. Confusing them is the most common and most expensive error a buyer makes in this state.
This is the rate that actually calculates your bill — but it applies to assessed value, not market value. The formula is (assessed value × general rate) ÷ 100. It is expressed per $100 of assessed value.
This exists to compare one municipality against another, assuming both are at 100% valuation. It should never be used to calculate an actual tax bill — but it is the only honest way to compare Kenilworth against Cranford, Westfield or anywhere else.
A general rate of $6.625 with an effective rate of 2.002% tells you one thing: Kenilworth's assessments sit far below market value. The median assessment is $172,700 while the median sale price runs near $602,000 — assessments are landing at roughly 29% of what houses actually trade for.
That is not a discount and it is not an error. When a municipality has not revalued in many years, assessments drift below market and the general rate rises to collect the same levy from a smaller assessed base. The two move together. A high general rate on a low base produces an ordinary bill.
Here is the error in numbers, because it is worth seeing. A buyer under contract at $602,000 who multiplies by the general rate calculates $39,882 a year and walks away from the town. The actual estimated median bill is about $11,441. That buyer just talked themselves out of a house over a formula they applied to the wrong number.
On the measure that permits comparison, Kenilworth does well. Its effective rate of 2.002% sits below the Union County median of 2.113%, and it has fallen meaningfully over a decade — from 2.64% in 2015. For context, New Jersey's statewide average effective rate runs around 2.3%, and Union County's average is often cited near 2.43%.
The estimated median annual bill is about $11,441. Set that against a median sale price near $602,000 and you are paying roughly 1.9% of market value — which is what a 2.002% effective rate should produce, and a useful cross-check that the numbers are internally consistent.
A Kenilworth property of roughly 1,500 square feet carried an assessment of $174,900 in 2009 and $176,100 in 2025 — a movement of about 1% across sixteen years.
Over that same period the borough's market moved a great deal more than 1%. That single parcel is the whole story: assessments here are a historical artefact, not a current valuation, and any figure derived from them needs the effective rate or the actual bill to be meaningful.
A national property-data platform reports a Kenilworth "median effective tax rate of 5.75%" alongside a median bill of $9,818. An effective rate of 5.75% is not possible in New Jersey — the statewide average is around 2.3% and the highest municipalities run near 3%. The figure appears to misapply a general rate. Treat any source reporting a New Jersey effective rate above roughly 3.5% as broken, and check its other numbers before using them.
And the comparison that matters for most Kenilworth buyers. Neighbouring towns with higher property values carry materially larger bills — Union County towns including Cranford, Westfield and Summit are commonly cited in the $12,000 to $20,000+ range. Kenilworth's advantage is not a lower rate so much as a lower base: a below-median effective rate applied to houses that cost less than the neighbours'. Both halves of that matter, and our Kenilworth and Cranford comparison works through the price side.
Your assessment is a fraction of your market value — which means a buyer doing their own arithmetic can arrive at a number four times too high.
A buyer who multiplies the $6.625 general rate by your asking price calculates a bill near $39,000 and moves on. Put the actual current tax bill in the listing materials — it is one of the strongest and most underused pieces of marketing a Kenilworth seller has, and it removes an objection before it forms. We handle that, price from recent closed sales rather than a value estimate running six figures behind, and bring the New York metro buyer pool to every listing.
New Jersey homeowners can appeal their assessment annually, and the deadline is firm. Appeals are filed with the Union County Board of Taxation in Elizabeth by April 1 — or May 1 in a municipality that has just undergone a revaluation or reassessment. Properties assessed above $1 million may appeal directly to the New Jersey Tax Court.
You do not win an appeal by showing your assessment is below your market value — everyone's is. The test is proportional. Divide your assessed value by the municipality's equalization ratio to get the assessor's implied true value. If that implied value exceeds your home's actual market value by more than 15%, you have grounds.
In a town with deeply discounted assessments, that is a harder bar than people expect. A $172,700 assessment on a house worth $602,000 sounds like an obvious over-assessment argument in reverse — but the ratio corrects for exactly that, and the question is only whether your parcel is out of line with your neighbours'. The evidence that works is comparable assessments on comparable nearby homes, plus recent comparable sales or an independent appraisal.
The practical implication for a recent buyer is worth stating plainly. If you just paid $650,000 for a house assessed at $180,000, your purchase price is not evidence of over-assessment — it is evidence the whole town is under-assessed, which the equalization ratio already accounts for. The appeal only works if your neighbours with similar houses carry materially lower assessments than you do. Pull three or four of them before you file.
And one thing to watch for. A municipality that has not revalued in many years may eventually be required to, and a revaluation resets every assessment to current market value. That does not automatically raise anyone's bill — the general rate falls correspondingly — but it redistributes the burden, and owners whose assessments were furthest below market see the largest increases. Ask the Tax Assessor whether a revaluation or reassessment is contemplated. It is a fair question and the answer is public.
For a buyer, the entire lesson reduces to one instruction: get the actual current tax bill on the actual parcel. Not the general rate times your offer. Not a listing site's estimate. The bill. It is a public record, the seller's agent can produce it in minutes, and it is the only number your lender will ultimately use.
Then build the all-in monthly properly — principal and interest, the real annual tax divided by twelve, and an insurance quote in your own name on that specific structure. Taxes go into your debt-to-income ratio, and lenders count them: an $11,000 bill adds roughly $950 a month to your qualifying calculation. That is the difference between qualifying for the house and not.
For a seller, the arithmetic runs the other way and it is an opportunity. Your assessment is a fraction of your asking price, which means any buyer doing back-of-envelope maths with the published rate will land at a wildly inflated number. Put the actual bill in your listing materials. In a borough where the effective rate is below the county median, the tax picture is a selling point — and almost nobody presents it as one.
And for anyone comparing Kenilworth against its neighbours, use the effective rate and nothing else. 2.002% here against a county median of 2.113% is a real, comparable, defensible advantage. Comparing general rates across towns with different assessment ratios is not a comparison at all — it is noise. Borough context sits in our Kenilworth guide, and the selling process in our seller's guide.
Ask the Tax Assessor one question before you buy: when did Kenilworth last revalue, and is another one contemplated? It is a public record and it takes one call. A borough whose median assessment is $172,700 against a market near $602,000 is a borough that has not revalued in a long time — and revaluations do eventually happen. When one does, every assessment resets to current market and the general rate drops correspondingly. The total levy does not change, but the distribution does — and the owners whose assessments sat furthest below market are the ones whose bills move most. That is not a reason to avoid Kenilworth. It is a reason to know where your specific parcel sits before you inherit someone else's assessment.
"I've watched buyers talk themselves out of Kenilworth over a calculation. They see six-point-six-two-five per hundred, multiply it by a six-hundred-thousand-dollar purchase price, get thirty-nine thousand a year and walk. The real median bill is about eleven-four. The rate is high because the assessments are low — median assessment is a hundred seventy-two thousand on houses selling for six-oh-two. There's a parcel in the borough that went from a hundred seventy-four-nine in 2009 to a hundred seventy-six-one in 2025. One percent, in sixteen years. So use the effective rate to compare towns — two-point-oh-oh-two here against a county median of two-one-one-three, which is a genuine advantage — and use the actual bill for everything else. Never the general rate times your offer."

What are property taxes in Kenilworth, NJ?
Kenilworth's 2025 general tax rate is $6.625 per $100 of assessed value, with an effective rate of 2.002% — below the Union County median of 2.113%. The median home is assessed at $172,700, producing an estimated median bill of about $11,441 per year. Do not multiply the general rate by a purchase price: assessments here run far below market, so that calculation produces a figure roughly four times the real bill. Verify the actual current bill on any specific parcel with the Tax Assessor.
Why is Kenilworth's tax rate so high?
It isn't — the general rate is high because the assessments are low. A median assessment of $172,700 against a median sale price near $602,000 means assessments run at roughly 29% of market value. When a municipality has not revalued in many years, assessments drift below market and the general rate rises to collect the same levy from a smaller base. The comparable measure is the effective rate — 2.002% in Kenilworth, below the county median and down from 2.64% in 2015.
Can I appeal my Kenilworth assessment?
Yes, annually, with the Union County Board of Taxation by April 1 (May 1 in revaluation years); properties assessed above $1 million may go directly to the NJ Tax Court. The test is proportional, not absolute. Divide your assessed value by the equalization ratio to get the implied true value — if that exceeds your home's market value by more than 15%, you have grounds. Your purchase price alone is not evidence, because the whole town is under-assessed and the ratio accounts for it. Comparable nearby assessments are the evidence that works.
What happens if Kenilworth revalues?
A revaluation resets every assessment to current market value and the general rate falls correspondingly. The total levy does not change — but the distribution does, and owners whose assessments sat furthest below market see the largest increases. Given that Kenilworth's median assessment is $172,700 against a market near $602,000, and one documented parcel moved about 1% between 2009 and 2025, ask the Tax Assessor whether a revaluation or reassessment is contemplated before you buy. It is a public question with a public answer.

Figures as of publication, from the sources noted, and subject to change. Kenilworth's 2025 general tax rate of $6.625 per $100 of assessed value, effective rate of 2.002% against a Union County median effective rate of 2.113%, a decline from 2.64% in 2015, a median assessment of $172,700 and an estimated median annual property tax of approximately $11,441, per NJTaxRecords.net drawing on NJ Division of Taxation and NJGIN MOD-IV composite assessment data. The individual parcel cited — approximately 1,512 square feet — is recorded at an assessed value of $174,900 in 2009 and $176,100 in 2025, per the same source, which notes that parcel geometry and assessment data derive from the NJGIN MOD-IV composite certified roll and that owner data is redacted under New Jersey's Daniel's Law. New Jersey's General Tax Rate is used to calculate tax due and equals $10 per $1,000 of assessed value; the Effective Tax Rate is used to compare one district to another assuming both are at 100% valuation and should not be used to calculate property tax. New Jersey's statewide average effective property tax rate is approximately 2.3%, with Union County's average effective rate cited at approximately 2.43%; the statewide average property tax bill was $10,597 per NJ DCA 2025 data; Union County towns including Cranford, Westfield and Summit are commonly cited in the $12,000 to $20,000+ range. Appeals: filed with the Union County Board of Taxation in Elizabeth, generally by April 1 (May 1 in municipalities that have undergone a revaluation or reassessment), with properties assessed above $1 million eligible to appeal directly to the New Jersey Tax Court; under the Chapter 123 ratio test, where the assessor's implied true value (assessed value divided by the equalization ratio) exceeds actual market value by more than 15%, there is a basis to appeal, with comparable sales and independent appraisal cited as strong evidence. Market figures referenced for context: a Kenilworth median home price of $602,000 as of March 2026 with an average sale price of $631,594 (Homes.com). One source discarded: a national property-data platform reporting a Kenilworth "median effective tax rate of 5.75%" alongside a median annual tax bill of $9,818. An effective rate of 5.75% is not attainable in New Jersey, where the statewide average is approximately 2.3% and the highest municipalities approach 3%; the figure appears to misapply a general rate, and neither figure from that source is relied upon here. Household income, school rating scores and crime data available from the sources consulted have been deliberately excluded, as we exclude such material for every community we cover. Assessments, rates, ratios and bills are specific to each parcel and change annually. Nothing in this article is tax, legal or investment advice. Verify the actual current assessment and tax bill for any specific property with the Borough of Kenilworth Tax Assessor, and consult your own attorney, accountant or tax appeal professional before acting.
