If you're comparing a home in Caldwell with one in a neighboring town this fall, the annual property tax line is probably one of the first numbers you check. In Caldwell, that number is about to be recalculated from scratch. The borough is finishing a full revaluation, and the new assessments are scheduled to take effect for the 2027 tax year.
That doesn't mean every bill goes up. It means today's tax line tells you how a house was valued against its neighbors under the old assessments. Once the revaluation lands, the house will be measured against current market value, and whether its share rises or falls depends on how its own value changed compared with the rest of Caldwell.
Caldwell's Assessments Sit at About 65 Cents on the Dollar
Essex County's final 2026 equalization table, certified April 2, 2026, puts the total assessed value of Caldwell's taxable property at $1,068,529,700. The state's estimate of what that property is worth on the market, its "equalized value," is $1,641,366,667. That makes Caldwell's aggregate assessment ratio 65.10%. Across the borough, assessments cover about 65 cents of each dollar of market value.
The borough's 2026 budget presentation, dated April 7, 2026, shows how that low base turns into a high rate. It lists 1,922 residential parcels with an average residential assessment of $427,668. It divides the amount to be raised, $36,157,954.97, by the same $1,068,529,700 in total assessments to reach an estimated 2026 tax rate of $3.384 per $100 of assessed value. The 2025 rate was $3.257. On the average home, the presentation estimates a 2026 bill of $14,472.29, up $543.14 from $13,929.15. The presentation labels these as estimates.
Do the math on that average assessment and you get a sense of the gap. $427,668 divided by 0.651 comes to roughly $657,000 in implied market value for the average Caldwell home. That's an illustration from a borough-wide ratio, not an appraisal of any particular house. Still, it shows how far Caldwell's assessments have drifted from what homes trade for.
What a Revaluation Does to the Rate, and What It Leaves Alone
The New Jersey Division of Taxation's revaluation handout explains the mechanics with a worked example. A town that needs to raise $15 million on $600 million of assessments has a rate of $2.50 per $100. After a revaluation doubles total assessments to $1.2 billion, the rate falls to $1.25. In the state's words, the revaluation "would not have caused an increase in total taxes to be collected by the municipality."
Apply the same arithmetic to Caldwell's 2026 figures. Raising Caldwell's assessments to the full $1,641,366,667 equalized value while holding the 2026 levy flat would bring the rate to roughly $2.20 per $100. The table below is illustrative only. The real 2027 rate will depend on the 2027 budget and on the final revaluation totals.
| Illustration using 2026 figures | Current assessments | Assessments at full market value |
|---|---|---|
| Borough total | $1,068,529,700 | $1,641,366,667 |
| Rate per $100, same levy | $3.384 (estimated) | about $2.20 |
| Home that kept pace with the borough, assessed $427,668 today | $14,472 | about $14,470 at roughly $657,000 |
| Same assessment today, but the home is now worth $750,000 | $14,472 | about $16,520 |
| Same assessment today, but the home is now worth $580,000 | $14,472 | about $12,780 |
The three homes in the bottom rows pay the same bill today. Under the illustration, they would pay three different bills once the revaluation lands. A revaluation doesn't change how much Caldwell collects. It changes how the bill is split among owners.
Why Two Caldwell Houses With the Same Tax Line Can Diverge
The state handout lists the situations that throw assessments out of line over the years: changes in a neighborhood or an individual property, swings in the economy and interest rates, "custom changes to a house" such as remodeling and additions, and zoning changes.
For a buyer looking at Caldwell this fall, that list is a set of questions to ask about each specific house:
- Has the kitchen, the bathrooms or the floor plan been renovated since the last assessment?
- Has living space been added, such as a finished level, a dormer or an addition?
- Is the house on a street or in a section where prices have climbed faster than in the rest of the borough?
- Is the house largely original, with its value rising roughly in line with the borough as a whole?
A house that answers yes to the first three is the kind of property the state describes as under-taxed relative to its neighbors before a revaluation. Its 2027 share is more likely to rise. A largely original house in a slower-moving section could see its share hold steady or fall. Two homes with identical tax lines on a listing today can end up in different places in 2027.
This affects sellers as well. A recently renovated Caldwell home listed this fall shows a tax figure that buyers may read as permanent. It's better to be upfront about the coming revaluation in conversations with buyers than to have it come up after an offer is signed.
The Calendar Between Now and the 2027 Bill
The borough announced the revaluation on October 7, 2025, and the work has followed a set schedule since then.
- October 8, 2025. Appraisers from Professional Property Appraisers began interior and exterior inspections.
- Through May 2026. Field inspections continued across the borough.
- By December 2026. All revaluation work is scheduled to be complete so the new assessments can be used for the 2027 tax year.
- Notice of the new value. Under state guidance, the revaluation firm has to mail each taxpayer a notice of the proposed new value before it goes on the tax list. That usually happens after November 10 and before December 31. The notice explains how to set up an informal hearing if the owner disagrees with the proposed assessment.
- May 1. The Division of Taxation's assessment and appeals page says that where a municipality has undertaken a revaluation, tax appeal petitions must be filed and received by May 1, rather than the usual April 1.
For someone under contract on a Caldwell home this month, that timing matters. The new valuation notice may arrive at the house while the sale is still in progress. The borough Tax Assessor, George Librizzi, is listed in the borough's announcement as the contact for revaluation questions, at 973-226-6349. Professional Property Appraisers can be reached at 1-866-957-1388.
Comparing Caldwell With West Caldwell and North Caldwell
Buyers looking in the 07006 ZIP code often compare tax lines across the three Caldwells. The same Essex County table puts West Caldwell's 2026 aggregate ratio at 65.84% and North Caldwell's at 71.25%.
Today, all three towns assess below full market value, so comparing their tax lines is a rough comparison between towns using somewhat different yardsticks. In Caldwell, the yardstick itself changes for 2027. A comparison you make this fall between a Caldwell listing and a neighboring one may not hold once Caldwell's new assessments are on the tax list. The total of what a household pays will still depend on each town's budget and on how each house's value has moved.

A Few Questions That Come Up
Does a revaluation mean Caldwell is raising taxes?
Not by itself. The state's own example shows total assessments going up while the rate comes down in proportion, with no increase in what the municipality collects. Any change in the total for 2027 comes from the 2027 budget, which is a separate process.
Will a Caldwell home's new assessment match what it would sell for?
The revaluation aims to assess property at true value. Appraisers study recent sales and adjust them to estimate the value of homes that haven't sold. The process also records building materials and dimensions from the inspections. The proposed figure appears on the notice the firm mails before the value goes on the tax list.
What should a buyer ask about a specific Caldwell listing right now?
Ask when the major renovations and additions were done, how the house compares with others nearby in condition and updates, and whether the sellers have received a revaluation notice. Those answers say more about the 2027 bill than the current tax line does.
