Trump threatens federal action to block NYC pied-à-terre tax

On August 11, 2026, President Donald Trump threatened federal intervention to block New York City's new pied-à-terre tax, calling it a "dangerous political experiment" that would destroy the city. The tax, championed by Mayor Zohran Mamdani, targets luxury second homes valued over $1 million to raise up to $500 million annually. Trump's threat follows an August 10, 2026 Staten Island court ruling that temporarily blocked the tax's rollout, which the city immediately appealed.
