This bill amends the procedure for overriding local tax caps by requiring a supermajority vote of the legislative body. Specifically, it repeals and reenacts RSA 32:5-b, III to stipulate that when a proposed appropriation exceeds the local tax cap, the voting must be conducted by ballot, excluding the question from the official ballot used for electing officers, except in certain cases. A 3/5 majority or a supermajority, as defined by local charters, is necessary for the appropriation to be approved. The bill also clarifies that only affirmative or negative votes will count towards this majority calculation.

Additionally, the bill includes provisions for how to handle appropriations related to bonds and multi-year expenditures, as well as specific rules for school districts that have adopted alternative budget procedures. It ensures that the new rules apply to existing local tax caps without requiring amendments or re-adoption by the towns or districts. The act will take effect 60 days after its passage.
