Mamdani Doxxes NYC Property Owners, Quietly Expands Reach of New Tax
From July 1, 2026 through June 30, 2028, the new tax will apply to condominiums and co-ops valued between $1 and $5 million.
New York City Mayor Zohran Kwame Mamdani is facing widespread criticism after his administration on Monday published a searchable database identifying wealthy property owners who may be subject to the city’s pied-à-terre tax. The administration says the database is intended to promote transparency. Critics, however, argue it effectively “doxxes” property owners by making them easier to identify and locate, unnecessarily exposing them to harassment, vandalism, and even potential acts of violence.
Mamdani is also drawing criticism for including properties valued between $1 million and $5 million in the database, despite repeatedly promoting the pied-à-terre tax as applying only to properties worth $5 million or more. As it turns out, that was part of the plan — which I’ll return to shortly.
The Department of Finance’s online database allows anyone to search properties and access the names and addresses of owners whose non-primary residences could be affected by the proposed tax.
A Department of Finance spokesperson told Fox News that state law required the publication of the property assessment roll: “As per State law, a property roll was released for public inspection. From this list, DOF will identify properties that may be subject to the new non-primary residence property surcharge.”
It’s true that property records have long been public. Even so, aggregating the city’s most expensive properties into a single, searchable database that anyone can access strikes me as dangerous. There’s no shortage of bad actors who could exploit such a list for nefarious purposes, from political targeting to criminal activity.
Zohran Mamdani has released the names and addresses of everyone who owns a second home in New York City valued at $1 million or more. This doxxing of “the rich” provides burglars and kidnappers with the identities and locations of some 960,000 wealthy NYC visitors. It’s worth…

The New York Post editorial board called the database Mamdani’s “enemies of the people” list and asked why no one at City Hall stopped this “amateur-hour idiocy?”
Because the Democratic Socialist crew is obsessed with naming and shaming their “class enemies”: As national DSA co-chair Megan Romer explained on Fox News Sunday, “We will win by making conditions so intolerable to the ruling class that they would rather give in to our demands than live with the disturbance we cause.”
An equally disturbing aspect of the database is its inclusion of properties valued between $1 million and $5 million. When Mamdani and Gov. Kathy Hochul first announced the pied-à-terre tax on April 15, the mayor himself said it was aimed at “luxury apartments worth more than $5 million whose owners don’t live full time here.”
A news release from Mamdani’s office at the time clearly stated the tax “will levy an annual surcharge on one to three family homes, condominiums and co-ops valued above $5 million when owners have a separate primary residence outside of New York City.”
According to the release, the new tax was expected to generate approximately $500 million in new revenue to the city.
Two weeks later, New York City Comptroller Mark Levine released an analysis estimating the tax would apply to roughly 11,200 high-value second-home properties, depending on the final design and exemptions. He also lowered the expected revenue from the tax to between $340 million and $380 million.
Last week, the Department of Finance released its preliminary tax roll which identified more than 31,000 properties as potentially subject to the tax. Bloomberg reported that this was far above the roughly 10,000 properties city and state officials had initially estimated when the measure was passed in May.
Few were prepared on Monday when it was reported that a staggering 960,000 properties could be subject to the tax. To be clear, this doesn’t mean that every property owner listed in the database will be required to pay this confiscatory tax, merely that they might be.
Many were shocked to learn that the tax would extend to second properties valued as low as $1 million. So, how did this number grow so large?
The answer lies in the fine print which states that from July 1, 2026 through June 30, 2028, the new tax will apply to condominiums and co-ops valued between $1 and $5 million. [One to three family homes must be worth more than $5 million for this tax to apply.]
According to New York City law firm Willkie Farr & Gallagher LLP, the law that was ultimately enacted treats condominiums and co-ops differently and includes a two-phase rollout:
Because New York City’s tax assessment system substantially undervalues many condos and co-ops, the law imposes a temporary Phase 1 (July 1, 2026–June 30, 2028) in which these properties can be subject to the tax if their Department of Finance valuation is $1 million or more. Beginning July 1, 2028, they transition to the same $5 million threshold as other residential properties.
Specifically:
For fiscal years 2026-27, and 2027-28, Class 2 Properties valued at $1M or more are subject to tax, at the following rates:
- Class 2 Properties valued at $1M to $3M: 4%;
- Class 2 Properties valued above $3M to $5M: 5.25%;
- Class 2 Properties valued above $5M: 6.5%.”
- One- to three-family homes, the tax only applies to properties valued at $5 million or more.
By including Class 2 properties valued at $1 million, the city has transformed the pied-à-terre tax from one marketed as targeting the ultrawealthy into one that reaches many middle-class property owners. For many New Yorkers, a $1 million condominium or co-op is hardly the hallmark of extravagant wealth, especially given the city’s exceptionally high real estate prices. As more property owners discover they could be subject to the tax — and realize their names and addresses are now part of a publicly searchable database — the political fallout is likely to be fierce.

Comments
It is time for a lawsuit, with Mamdani personally named.
Looks like exactly what a small time dictator would do. We’ll New Dork you set on your hands deal with it.
War is declared. Class Warfare. No going back.
May God help us.
Tough one- I haven’t much sympathy for people who have secondary pads that they call pied a terres. I suspect most are brie sucking, smarmy woketards.
THEY aren’t calling them ‘pied a terre’.
The vulgar rich islamocommunist terrorist destroying New York and his like minded useful fools ARE.
Because that’s how THEY think. And the words THEY choose.
To show that they’re educated.
And wealthy.
How do you know what they call them?
I walk among them.
Unless they stole the homes or the funds to purchase them, why should they be punished?
Because they suck
Pot, meet kettle.
Ahh. look. A communist resident of this blog.
No, a Nazi.
Anyone who tries to steal from another or approves of such theft, either through conventional theft or through punitive taxes, is an asshole.
By the sound of things, that means you.
There have been several articles pointing out that many extremely wealthy people subject to the tax say they are overjoyed to pay it. Do you deny them their joy?
“There have been several articles pointing out that many extremely wealthy people subject to the tax say they are overjoyed to pay it. Do you deny them their joy?”
Funny. If they were overjoyed to pay that tax, one would think they would have been voluntarily contributing such additional taxes to the government already. There are no laws against sending amounts over and above what is due for taxes,
Regardless, those who are NOT “overjoyed”, should not have to pay these punitive taxes. Their success should not be punished, no matter how resentful and jealous those who are less successful are. Such punishment is theft.
Or, they can afford what you can’t.
Be careful about who your complain about my friend, you may be next.
Mamdani Doxxes the people who voted for him. Ha ha.
By definition none of these people could have voted for him. Their primary residence is somewhere else, so they can’t vote here.
Perfect, so they can’t vote against him which makes stealing from them even easier for him.
You’re assuming facts not in evidence. There have already been multiple reports of people on this list that have lived permanently in the residences for DECADES.
This is just evil. Glad to see you apologize for it though.
Milhouse is being a “maroon” here on this subject.
Was the law written that ONLY non residents get taxed or is it just there are more non residents that own a second place than residents?
Pretty sure there was no distinction over resident or non resident. Anyone with a second home *eventually* will get hit with the tax.
Vote for stupid, you get to pay for stupid.

And once again nothing will happen.
Marly Hornik, the founder of RealAmerica.Vote and NY Citizens Audit, has suggested that the 2025 election included large numbers of unqualified or nonexistent voters. But that’s only part of the problem.
“I actually don’t know whether Mamdani won the mayoral race, and I’m not here to say that he didn’t,” Hornik said during a July 22 interview on New York radio station WABC’s “Sid & Friends in the Morning” program.
“The problem we uncovered is that the New York City and the New York State Boards of Elections have no idea if Mamdani won the mayoral election either. And that’s where the rubber meets the road here.”
After examining 1 million of the total 2.2 million voters who participated in the election, her organization discovered that 7 percent were nonexistent in records, 6 percent had fake Social Security numbers, and 10 percent didn’t even live in NYC.
In total, they identified 230,000 illegal votes, which exceeded Mamdani’s 207,000 vote margin of victory over former New York Gov. Andrew Cuomo, who ran as an independent.
And this was despite Hornik needing to still review the remaining 1.2 million voters.
Did you not read the post? Or anything else about it? The post makes it clear multiple times that the tax applies only to residences whose “owners have a separate primary residence outside of New York City”.
The tax may only apply to 2nd homeowners but many of the publicized names are for people who actually live there full time.
Sanddog, the list is of people who may be subject to the tax, putting them on notice so that if they believe it doesn’t apply to them they can inform the city. Not everyone on this list will end up owing the tax. My guess is that most won’t end up owing anything; that the list is massively overinclusive, just to make sure they didn’t miss anyone. Or because they were too lazy to narrow it down, and expect the property owners to do that work for them.
I repeat what I wrote in another thread yesterday: Socialism is inherently evil.
So basically a list of expensive properties that are vacant a good part of the year. Can’t think of a single thing that could happen because he published such a list. Let’s just serve it up to all the criminals, here is a list of probably empty expensive houses to rob. I hope everyone who is robbed sues the crap out of him saying he gave the criminals the info.
I’m sure a lot of people who claim their primary residence is outside the city actually do live in the city, but claim otherwise to evade NYC income tax – which is enormous. Mamdani is actually being very clever here. If the claim residency, they will owe enormous back taxes on income. If they simply pay the new tax, he still got them.
Not necessarily; there is a strong probability that many are likely snowbirds and might not have changed their primary residence to the state where they own an investment property or vacation home (i.e., Texas, Florida), and thus are still registered to vote in NY. Even if the homeowner establishes residence elsewhere, outside NY, they still must pay property taxes and HOA fees. The other consideration is that individuals or their personal trusts do not own the properties on Mamdani’s list, but by the business they own or are employed by.
The list is of properties whose owners’ primary residence is outside NYC.
You’re assuming facts not in evidence. There have already been multiple reports of people on this list that have lived permanently in the residences for DECADES.
This is just evil. Glad to see you apologize for it though.
I *love* that you’re doing your absolute best to be an absolutely evil D-Bag by ignoring evidence that there are names on that list of people that actually live there full-time.
You also appear to be ignoring the fact that the evil piece of trash that is doing this, your pal mamdami or however the hell you spell his worthless name, LIED about A) the values of the properties he would go after and B) the numbers affected because of the values.
But you appear to be all in on the side of confiscation of wealth. So, screw those folks, right?
You’re the one assuming facts not only not in evidence but completely contrary to the evidence, such as calling Mamdani my pal, or claiming that I support confiscation of wealth (though if it happens to socialists I will say that they’re morally estopped from complaining about it).
Well, if you don’t want to be accused of being for confiscation of wealth, maybe you ought to stop defending it so ardently.
Or maybe you’re just a lying p.o.s.
I’ll go with lying p.o.s.
Fredman, now you’re just a freaking liar. In all my many years here I have never supported confiscation of wealth, or any other socialist policy. Not even once, And everyone here knows it.
It means that it is unlawful to do so not that they can’t and certainly it doesn’t mean they didn’t.
Perhaps ‘should not have been able’ is more accurate. In a list of nearly a million I suspect at least one has voted in a NYC election despite ‘safeguards’.
I’d be interested to see how many of the folks on the voter rolls of NY are simultaneously on the rolls of another State. Frankly I’d like to see that analysis for every State then remove the fraudulent registrations and put someone in prison for it; either the clerk or supervisor or Sec State who allowed it or the registrant but somebody gotta go to prison to create functional deterrence or it won’t stop.
By design they should not have. As the owner of several homes, I am mistakenly invited to vote regularly. But I don’t call none them a freakin pier de Terry. Sounds pinko and artsy. That type buys gold toilets and rotting bananas at Art Basel
Neither do most of these property owners.
No, it doesn’t necessarily mean they can’t vote locally … they could have a local residence AS WELL as the “non-primary” properties being listed.
And of course, not being local doesn’t mean they aren’t being registered ANYWAY … as so many “undocumented/illegal voters” are registered.
The tax is laid on property owners whose primary residence is not in the city.
According to the NY Post, all owners of the specified properties, whether the properties are primary residences or not, will received tax bills. They will then have a number of weeks to demonstrate that the properties are their primary residences if they want to avoid the tax. This will create headaches and anger among hundreds of thousand of condo and co-op owners in NYC.
I thought I read that it was primarily Gen Z voters who turned out to elect Mamdani. In that case, most of them probably don’t own property and are not affected by this.
Approximately 38% to 39% of New York City’s resident population is foreign-born, totaling about 3.1 million people. That’s who voted for the scumbag.
https://www.google.com/search?q=39%25+of+NYC+residents+are+foreign+born&rlz=1CAOBDQ_enUS1042US1042&oq=39%25+of+NYC+residents+are+foreign+born&gs_lcrp=EgZjaHJvbWUyBggAEEUYOTIKCAEQABiABBiiBDIKCAIQABiABBiiBDIHCAMQABjvBTIHCAQQABjvBdIBCTUyMTY2ajBqN6gCALACAA&sourceid=chrome&source=chrome.ob&ie=UTF-8
Approximately that percentage of New Yorkers have always been immigrants. That’s just what NYC is.
When they declare they’re going to “tax the ‘rich,'” you can be sure that the definition of “rich” is deliberately very fluid.
Exhibit A: Federal income tax….
The definitions has been scientifically tested and found to be made of flubber.
The tax assessor for Clallam Co. sends out a photo team every few years and posts them on the searchable property tax database. They also have a team scouring real estate photo listings for proof of undocumented improvements to increase the valuation and tax rate. My new neighbor got caught up in that when the listeing he bought from showed a finished basement that the previous owner never reported. It increased his tax by half. The on site photo crew comes unannounced, walk through a locked gate, takes photos and posts them without consent of the owner. The most recent batch showed our vehicles in front of the house, and zoomed in, license plates.
I fought with the assessor over the detail showin in the pics of our home, because we’re in the sticks and have some crime problems here. Just a 1/4 up the road, there’s a turn out where people park, hang out, do drug deals, etc. It’s also at the intersection of the only access to our hill – where a team of thieves could post a scout, and alert an accomplice to our comings and goings – made much easier by the county twits posting photos that tie our vehicles / plates to our house. So after a week of arguing and threatening legal action, the clerk blotted out our vehicles.
I did not win the argument about public photos though; I understand the rationale of taking them for records and code compliance, but why do they have to be public? They really didn’t have basis other than the flimsy “the people have the right to know” … and my reply “no, private property is private, a right I assert by a locked gate at the entrance. You trespassed to take that photo. And by posting it publicly, you effectively allow the public to trespass as well”. If I had money to burn, I’d sue.
Don’t worry – they’ll be using drones for that stuff (along with snooping for code violations) before you know it. They’re also planning to outfit garbage trucks with AI cameras to use for similar purposes.
And here we all thought the future would be about flying cars like the Jetsons. Laugh’s on us.
George Jetson was dyslexic. It was actually “flying narcs.”
Where the hell is Clallam Co.?
What a horrible place to live, much like NYC
Washington? Lefty heaven
Don’t understand why a 51-53/49-47 divide is lefty heaven? Clean up the voter roles, get rid of same day registration, mail in, no identification voters, it would potentially swing back red.
Clallam County is essentially the north end of the Olympic Peninsula in Washington State.
God’s country, but for the nose rings and blue haired harpies in town. Typical 51/49 split at the state level – we’re gerrymandered in with the lefty loons in Olympia at the nat’l level so, yer basic red vote nullification. I’ve run the numbers on leaving, costs much less to stay once r/e fees are factored in and the cost to relocate, amortized by remaining life expectancy. County cops are doing their job with the scum – great little enclave of well-armed neighbors, self included.
I would not be surprised if this was done so squatters could take over these places. Of course the real owners would still be required to pay all the taxes.
Gonna be a ton of properties suddenly ‘re-valued’ at $999,999.99
The valuation is not up to the owner. On the contrary, the whole reason co-ops/conodos (as opposed to other kinds of homes) are temporarily starting from $1M rather than $5M is the (alleged) fact that the city has notoriously undervalued such property, so that something that city says is worth $1M is really worth closer to $5M. Supposedly in the next few years the city will go about revaluing the properties properly, and then the tax will start kicking in at $5M. Which is very unlikely, but it does show that the owner can’t decide the valuation.
Anyone who ever read a history book knows this is the next step in the communists’ dekulakization program where they name & shame the Kulaks (counter-revolutionaries) as a precusor to confiscating their wealth.
Take a wild guess as to what the commies do next to the wealthy…
Yes, I believe you have captured Mamdani’s end-game move, which is the confiscation of private property and owned by the city/state.
Not even surprise. The Communists always find a way to steal more
Years ago, during the time of the Soviet Union, I visited the summer dacha of Lenin… which includes the bedroom where he died..all preserved as it was. The house, of course, was confiscated from the upper class that didn’t survive the Revolution. NYC is playing the slow confiscation and I imagine many of Mamdani’s cohorts are salivating at moving in. Also thinking of Wannsee in Berlin…. the owners swept aside for the Third Reich. You will own nothing (and can’t afford to) and you will be happy (or else). Class warfare right down to the lowest common denominator. In the meantime, the new World Trade Center will have minarets and the call to prayer 5 times a day. NYC will be Not Your City….
The existence of this searchable database is a non-story..
This looks like the property tax rolls that are available to the general public all over the place. Not every municipality, but many.
When I was in the real estate market, I pulled this kind of information for any property that was vaguely interesting.
While many areas have searchable databases of property information, this particular database makes it easier to see the properties of the accused “rich” and does not bury them in all of the other records. My local county does not allow searching by estimated value while this database does exactly that.
I read that the “pied a terre” database is a separate database in order to make it easier to identify those properties that will be subject to taxing.
It’s an extract of the main database.
A separate list,.particularly given the context of Mamdani and lefty violence, seems unnecessary and vindictive. I don’t have a problem with a searchable database that has a filter function to search for specific types of properties by price, zip code, tax status or primary residence v rental or 2nd home. More transparency about tax rolls is valuable to the public. Now there’s an easily accessible list of properties by owner/location to use to compare to voter registration rolls in NY and in other States to see.if anyone holds voter registration in multiple States. To check for other tax related or mortgage related financial transgressions like claiming a NYC property as primary residence on a loan application to get a lower interest rate. If only 1% of that 960K did something shady that’s 9,600 violations of some sort. I’d be surprised if it was only 1%.
“A separate list,.particularly given the context of Mamdani and lefty violence, seems unnecessary and vindictive.”
Have you noticed how much Mamdani enjoys being snarky and vindictive?
While this tax is purely about soaking “the rich” and punishing them for nothing more than being successful in life, there are cities that have a similar tax for better reasons.
Jerusalem has a serious problem with people who own an apartment there, use it a few weeks a year, and the rest of the year it lies empty. The problem is that there are entire neighborhoods like this, and when the owners are all away they’re ghost towns, which invites crime.
So the city doubles the tax on apartments that are vacant for more than 3 months in the year. It determines this mostly by looking for near-zero water and electricity usage, and then asking the owner whether it was occupied. This is supposed to encourage owners to make use of their apartments, either by having a family member live there, or by putting in a tenant.
(Many years ago, one of my cousins had a lease on an apartment in Jerusalem that specified that the owner needed occupancy for two weeks, twice a year, so the tenant would have to find somewhere else to live for those four weeks.)
You know what also could use a whole bunch of transparency?
The names and addresses of Mamdani’s extended family tree.
I think Mamdopey needs to read Atlas Shrugged and realize that he’s James Taggart. Accept old Jimbo there was likely smarter than this hateful moron, as he at least had self awareness that he was motvated by destroying people who were more productive and successful than him,
Mamdani is enjoying the attention he’s getting way too much. I wish someone would wipe that snarky grin off his face.
Too much yelping here about what is/isn’t a pied a terre. The whole point is that Mamdani has decided to tax the wealthy in whatever way he can drum up. This is his blatant attempt to do that and the pushback is great to see.
Socialists are going to socialist. That’s to be expected when one is elected.
Mamdani caught nearly a million NY property owners in a catch 22. To avoid the tax, you either have to prove the valuation is less than 1 million (good luck) or prove that you are a resident. If you are a resident, you owe all sorts of other taxes billed to residents like city income tax and car tax – which could be much more than the pied a terre tax. So if you prove you are a resident, you get hit for evasion of income tax, car tax, or other taxes. Mamdani is actually very clever. He knows what he is doing. Most who are actually residents but evading other taxes will simply suck it up and pay the new tax.
