THE MANSION TAX BACKFIRE: HOW NEW JERSEY’S NEW FEES ARE PUSHING HOMEOWNERS OUT OF THE STATE
Seller signing New Jersey mansion tax document at a real estate closing table, showing the tax burden shift onto sellers for million dollar home sales
If you read our earlier guide, “NJ Mansion Tax 2025: Changes & Guide for Sellers,” you already know the state completely rewired how high end homes are taxed. The old one percent mansion tax structure shifted to a seller-paid model and added steep new tiers starting at two million.
That article covered the policy shift. This article shows what has happened since.
Using verified NJMLS data through November 2025, we now have a clear picture of how Bergen County’s two million plus market reacted. These new fees are reducing seller net proceeds, slowing momentum, and pushing more homeowners to consider leaving New Jersey altogether.
The New Tax System: A Costly Cliff at Two Million
The updated law introduced a Supplemental Realty Transfer Fee that applies to the entire sale price once a home crosses into a higher tier.
Over 1,000,000 to 2,000,000: 1.0 percent
Over 2,000,000 to 2,500,000: 2.0 percent
Over 2,500,000 to 3,000,000: 2.5 percent
Over 3,000,000 to 3,500,000: 3.0 percent
Over 3,500,000: 3.5 percent
This is not a marginal tax structure. Once a price crosses a threshold, the higher percentage applies to the entire sale price.
A sale at two million results in a twenty thousand tax.
A sale at two million twenty thousand results in a forty thousand four hundred tax.
A small price increase can trigger a large jump in tax. Pricing near the thresholds now requires precision and strategic planning.
How Buyers Reacted Once Sellers Started Paying the Tax
Buyers adjusted their behavior quickly. Once they realized sellers were responsible for the full mansion tax, negotiation leverage shifted.
Sale-to-list ratios in the luxury segment declined.
Inventory surged to thirteen months for homes priced above two million.
And most importantly, market momentum reversed.
Homes Stopped Speeding Up. The Market Reversed After the Mansion Tax.
In the first half of 2025, luxury homes were selling faster every month. Days on market dropped from 29 days in January to just 13 to 14 days in May and June. Buyers were aggressive, competition was strong, and the market was accelerating.
That acceleration ended the moment the new mansion tax took effect in July. Instead of continuing to speed up, the market reversed direction. Days on market began rising again, reaching 18 to 19 days in September and October and settling around 17 days in November.
The supplemental tax did not cause a dramatic collapse, but it clearly ended the red-hot spring and added enough friction to slow luxury sales. Sellers now face more hesitation, more negotiation pressure, and a market that feels noticeably different.
Why This Matters to Every New Jersey Homeowner
It may be tempting to assume this only affects wealthy sellers. That is not the case.
Luxury sales influence local tax structures.
Slowdowns at the top often signal slowdowns in the mid-range.
When high income residents leave, municipal budgets strain.
A stalled high end market reduces move-up and move-down inventory.
Out-migration trends eventually affect affordability statewide.
The luxury market is the early warning system for New Jersey real estate.
How to List, Market, and Price Strategically Under the Mansion Tax
As a licensed New Jersey real estate agent, I help sellers create pricing and marketing strategies that protect their equity. Under the new mansion tax structure, this is more important than ever.
Choosing the right pricing threshold can save tens of thousands. Listing below a tax tier often produces a higher net than listing slightly above it.
Marketing must be strong and fast. High end photography, videography, compelling copy, targeted digital exposure, and agent-to-agent communication reduce days on market and improve negotiation leverage.
Strategic pricing can generate higher engagement and possible multiple offers, which helps offset buyer hesitation.
Before listing, I prepare a detailed seller net sheet that includes the standard RTF, the supplemental tax, commissions, expected concessions, and carrying costs. This ensures sellers know exactly what they will walk away with.
