New York City Mayor Zohran Mamdani’s proposed pied-à-terre tax is moving forward as part of an effort to close the city’s widening budget gap. The idea is to tax non-resident owners of luxury second homes valued at $5 million or more.

It sounds like a populist fix: make wealthy absentee owners pay more while sparing middle-class homeowners a tax hike. But history shows that such taxes rarely deliver on promises to boost affordability or generate meaningful revenue.

Versions of second-home and vacancy taxes are spreading across global cities, from Vancouver and Toronto to London and Paris.

These policies share a common political narrative, targeting well-off property owners who leave high-end apartments empty while local residents struggle with housing costs. Yet, their results have consistently fallen short of expectations.

In Canada, Vancouver’s “Empty Homes Tax” was touted as a success story, designed to convert vacant luxury units into rentals.

While the initiative reportedly raised millions in its early years and was channeled into affordable housing programs, it still represents only about 1% of the city’s total tax take. Housing affordability in Vancouver remains dire, and average rents continue to climb.

London’s experience offers a cautionary parallel. Officials there imposed surcharges on second homes and vacant units with the hope of nudging vacant properties into the rental market.

Years later, the policy barely moved the needle on rental affordability. What it did achieve was a headline-grabbing show of “doing something” while failing to address the root issue, restrictive housing supply policies that prevent new building.

Paris followed a similar path. The French capital has raised its vacancy tax multiple times, and city officials now hope thousands of homes will re-enter the rental market.

Yet France’s Cour des Comptes found that despite the rhetoric, vacancy rates barely budged. It concluded that the taxes “do not appear to have had a significant effect on the overall number of vacant homes.”

Economists like Paul Cheshire of the London School of Economics argue that these taxes miss the mark because they focus on demand rather than supply.

“The biggest misconception is that these taxes will improve housing affordability in large super cities,” he said. “The problem is mainly constrained housing supply via policy.”

Cheshire’s observation points to the heart of the issue: cities like New York have made it practically impossible to build new homes quickly enough to meet demand.

In New York’s case, the economic logic appears even flimsier. According to projections, the city could net as much as $500 million annually from the new levy. But as Urban-Brookings Tax Policy Center researcher Thomas Brosy notes, those figures may be “optimistic.”

He estimates a more realistic range at $340 to $380 million — meaningful, yes, but far below what the city needs to solve its structural fiscal imbalances.

New York City’s own comptroller has echoed those doubts, warning that behavioral changes by owners will likely erode the tax base.

Wealthy homeowners could convert properties to primary residences, rent them to relatives, or pursue legal loopholes to reduce liability. The result may be lower-than-expected revenue and little change to the broader housing supply.

Beyond its limited fiscal appeal, the new levy risks sending an unintended message to high-net-worth individuals still willing to invest in New York real estate.

Billionaire investor Ken Griffin already criticized the idea after being singled out by Mamdani in a video, prompting concerns about possible business relocations.

While no one expects a mass exodus, history shows that cumulative tax burdens drive long-term migration trends among investors, entrepreneurs, and retirees.

The evidence is clear in the domestic migration from states like California and New York to Florida and Texas. The pattern repeats internationally: new wealth leaves high-tax cities such as London for Dubai and Singapore, which offer low property taxes and economic incentives.

“Tipping points emerge from cumulative burdens rather than isolated surcharges,” explained Abir Mandal of the Tax Foundation.

That cumulative effect matters more than any single policy. A pied-à-terre tax alone will not empty Manhattan, but it adds to an atmosphere of hostility toward investment capital.

Combined with New York’s already rising regulatory costs, it may push future business and development elsewhere at the margin.

Even so, Mamdani’s proposal remains politically appealing because it targets a small, affluent group without touching the broader voter base. It gives the mayor symbolic distance from everyday property tax hikes, while letting him claim action on inequality.

In essence, the tax functions as political theater rather than fiscal strategy.

If history is any guide, the “luxury vacancy” taxes of New York’s peers have achieved little more than modest revenues and moral satisfaction for politicians.

The real determinant of affordability is not how many luxury penthouses sit dark at night, but how much new housing supply gets built. Until policymakers confront that challenge head-on, symbolic taxes on the wealthy will remain a glossy distraction from the structural issues driving urban housing crises.
