What does the Massachusetts estimate not include?
Municipal budget data is sourced from Schedule A reports filed with the Massachusetts Division of Local Services. When scraped municipal subcategories exceed Schedule A totals (e.g., departmental budgets that include centrally budgeted benefits), subcategory amounts are deduplicated and proportionally scaled back to the Schedule A category total. Property tax rates are set annually by each municipality.
