This bill establishes new property tax classifications for the city of Watertown for fiscal year 2027 and subsequent years. It allows the commissioner of revenue to adjust the minimum residential factor, overriding existing laws that would typically govern this process. Specifically, the bill sets the new minimum residential factor at 50 percent, with the possibility of upward adjustments to ensure that the tax levy on any class of real or personal property does not exceed 175 percent of the full and fair cash valuation of taxable properties in Watertown.

The bill explicitly states that these changes are made notwithstanding section 1A of chapter 58 of the General Laws or any other conflicting laws, rules, or regulations. It is designed to provide flexibility in property tax assessments while ensuring that the tax burden remains equitable across different property classes. The act will take effect immediately upon its passage.
