The municipal officers shall determine the municipal fiscal year.
A municipality or plantation may raise one or 2 taxes during a single valuation if the taxes raised are based on appropriations made for a municipal fiscal year that does not exceed 18 months. A municipal or plantation fiscal year may extend beyond the end of the current tax year and the municipal officers or assessors of a plantation, when changing the municipality's or plantation's fiscal year, may, for transition purposes, adopt one or more fiscal years not longer than 18 months each.
