Mamdani Threatens 9.5% Property-Tax Hike as Last Resort; Council Counters with $6B Alternative

As Albany negotiations drag on (8th extender expires Mon May 4, no deal yet) and the May 12 NYC executive budget release approaches, Mayor Mamdani has formally floated a 9.5% across-the-board property-tax-rate hike as a "last-resort" tool to close the $5.4B-$6B FY27 gap if Albany fails to deliver pied-à-terre tax (~$500M), corporate hike (~$1.75B), or millionaires tax (~$3B). Speaker Menin's Apr 1 NYC Council preliminary budget response identified $6.033B over two years as an alternative path: $3.482B from re-estimates, $2.022B from efficiencies and savings, $529M from revenue enhancements — explicitly avoiding both property-tax hikes AND drawing down the city's $1.2B multi-year reserves. Mamdani called the Council plan "unrealistic," accusing them of double-counting savings already booked. The disagreement is now the central flashpoint heading into May 12. Comptroller Levine has warned property-tax hikes could trigger commercial-real-estate vacancy spirals; the CBC May 2 "Competitive NYC" report compounds the political risk by tying tax-the-rich approaches to NYC's 31% drop in millionaire share since 2010.
