An Act relative to property tax classification in the city of Boston

This bill directs the Boston Commissioner of Revenue to gradually increase the minimum share of property taxes paid by residential homeowners from 45% in 2025 to 50% by 2028. The legislation includes specific caps on how much of the total city tax levy any single property class can bear, ensuring that residential taxes do not exceed certain percentages of the overall valuation. Additionally, it allows the city to delay this transition by one or two years if it chooses to implement the changes starting in 2026 or 2027 instead. These adjustments apply to all residential property in Boston for the specified fiscal years, with the goal of shifting a larger portion of the tax burden to other property classes over time.
