Long Island school districts are projecting an average 1.8% rise in property taxes next year, the lowest increase in five years, according to the state comptroller’s office.

However, at least four districts are expected to propose overriding the existing tax cap – Bridgehampton, Greenport, Three Village and Wantagh.

Bill Heidenreich, the president of the Nassau Council of School Superintendents, called it a “rarity” that so many schools would consider piercing the tax cap.

“Different districts are at different places financially and there's a desire to retain programs and activities for students,” he told News 12. “By and large, it is a challenge to pass a budget at the 60% if it's not tax-cap complaint.”

Under state law, 60% of people within a school district would have to vote to approve overriding the cap tax restrictions. New York sets a baseline restriction on annual increases in school property taxes of 2% or the inflation rate, whichever is lower.

School budget voting is set for May 18.
