Bromance Over? Why A Tax Plan Led Trump To Accuse Zohran Mamdani Of 'Destroying' New York

Trump’s attack on NYC Mayor Zohran Mamdani centres on a proposed ‘pied-à-terre tax’ targeting the ultra-rich. Here’s what the policy means and why it has sparked a political clash.

As New York City confronts a widening fiscal deficit and an intensifying affordability crisis, a proposed tax targeting ultra-wealthy property owners has triggered a sharp political flashpoint. At the centre of it is US President Donald Trump, who has launched a fresh attack on New York Mayor Zohran Mamdani, accusing him of “destroying" the city through aggressive tax policies.

Trump Slams Mamdani: ‘Destroying New York’

In a post on Truth Social, Trump directly targeted Mamdani’s economic agenda, linking it to what he described as a broader decline in the city.

“Sadly, Mayor Mamdani is DESTROYING New York!" Trump wrote. “It has no chance! The United States of America should not contribute to its failure. It will only get WORSE. The TAX, TAX, TAX Policies are SO WRONG. People are fleeing. They must change their ways, AND FAST. History has proven, THIS ‘STUFF’ JUST DOESN’T WORK."

The outburst came amid Mamdani’s push to introduce a new tax on ultra-wealthy property owners, particularly those who own high-value homes in New York but do not live there full-time.

While Trump claimed that residents were “fleeing" the city due to such policies, there is little evidence to support that assertion, according to The Independent.

What Is The ‘Pied-à-Terre Tax’?

At the heart of the controversy is the proposed “pied-à-terre tax" — an annual surcharge on luxury residential properties valued at $5 million or more that are not used as primary residences.

Backed by New York Governor Kathy Hochul and Mayor Mamdani, the proposal targets ultra-wealthy individuals who invest in New York real estate but primarily live elsewhere, either outside the city or outside the state.

The tax would apply to one- to three-family homes, condominiums and co-ops owned by individuals whose main residence is not in New York City. In effect, it seeks to capture revenue from high-end properties that often remain unoccupied for much of the year.

As Hochul framed it, these homes are “part of our skyline," but their owners are not “part of our city".

“If you can afford a $5 million second home that sits empty most of the year, you can afford to contribute like every other New Yorker," she said.

The proposal is also tied directly to New York City’s fiscal challenges. The city’s budget deficit is projected to reach $5.4 billion. Officials estimate the tax could generate roughly $500 million annually, though earlier assessments of similar proposals suggested a lower yield of about $232 million, according to The Hill.

The measure is expected to impact around 13,000 high-value properties.

While final rates are yet to be formalised, previous versions of the proposal used a graded structure. Properties valued between $5 million and $6 million could be taxed at 0.5 per cent on the value above the threshold, with rates rising progressively for more expensive homes, potentially leading to substantial annual levies for ultra-luxury properties.

Why Is New York Pushing This Tax Now?

The push for the pied-à-terre tax is rooted in both fiscal urgency and a broader political agenda centred on affordability.

Mamdani has consistently advocated taxing the wealthy as a way to fund public services and ease the cost of living in one of the world’s most expensive cities. The new tax reflects that approach, while also emerging as a politically viable compromise.

While Mamdani had earlier proposed broader tax hikes on high earners and corporations, Hochul had resisted those measures. Targeting luxury second homes, however, has gained wider political acceptance.

The proposal also draws on data suggesting that a significant portion of high-end housing stock remains underused. According to the New York City Housing and Vacancy Survey 2023, around 59,000 units were “held for seasonal, recreational, or occasional use".

Mamdani has also dismissed concerns that wealthy residents would leave the city due to higher taxes, calling such fears “imagined".

What Has Mamdani Said About The Tax?

Announcing the proposal, Mamdani framed the tax as a targeted measure aimed squarely at the ultra-rich.

“Well, today we’re taxing. I’m thrilled to announce we’ve secured a pied-a-tierre tax, the first in New York’s history. This is an annual fee on luxury properties worth more than $5 million whose owners do not live full-time in the city," he said.

He emphasised that the tax is designed for those who treat New York real estate primarily as an investment.

“This pied-à-terre tax is specifically designed for the richest of the rich. Those who store their wealth in New York City real estate, but who don’t actually live here. But even so, they are able to reap the huge financial rewards of owning property in… the greatest city in the world," he said.

In a joint push with Hochul, Mamdani also underscored the fairness argument behind the proposal.

“Alongside the governor, our administration is fighting every day to make sure we address this fiscal deficit fairly, where the wealthy contribute what they owe and our budget reflects our commitment to the working New Yorkers being priced out of our city," he said.

From ‘Nice Guy’ To ‘Destroying New York’: The Trump-Mamdani Relationship

The latest clash marks a dramatic turn in what has been a rapidly shifting relationship between Trump and Mamdani.

During his election campaign, Trump had openly attacked Mamdani, calling him a “radical socialist" and a “communist", warning that he would turn New York into a “third-world country" and even threatening to cut federal funding if he won.

Mamdani, in turn, positioned himself as a direct ideological counter to Trump, responding sharply to such threats. “Donald Trump, since I know you’re watching – turn the volume up," he had said, adding: “To get to any of us, you will have to get through all of us".

Yet, after Mamdani assumed office in January 2026 as New York City’s first Muslim and South Asian mayor, the relationship took an unexpected turn. A much-anticipated White House meeting — expected to be a confrontation — instead became notably cordial.

“I will say there’s no difference in party. There’s no difference in anything, and we’re going to be helping him to make everybody’s dream come true, having a strong and very safe New York," Trump said after their first meeting.

Mamdani described the interaction as “productive", saying: “We spoke about rent, we spoke about groceries, we spoke about utilities… I appreciated the time with the President."

For a brief period, the two leaders maintained a surprisingly cooperative tone, even as their ideological differences remained stark.

The first visible cracks appeared during a dispute over a snow-shovelling programme, when Trump criticised Mamdani’s requirement for strict identification for workers while opposing voter ID laws.

By February, Trump had resumed attacking Mamdani, referring to him as “the new communist mayor of New York City", though he still described him as a “nice guy" with “bad policy".

The latest criticism over the pied-à-terre tax marks a sharper escalation.
