How Property Tax Works

Norfolk County, Massachusetts operates under a decentralized property tax system where individual municipalities set their own tax rates and collect property taxes to fund essential local services including education, public safety, infrastructure maintenance, and municipal operations. The county encompasses 28 cities and towns, each with varying tax rates based on local budget needs and property values. Property taxes in Norfolk County typically represent the largest source of revenue for municipalities, directly supporting schools, police and fire departments, road maintenance, and other critical community services.

The effective property tax rates across Norfolk County municipalities have shown moderate fluctuation over recent years, with the average rate of $15.97 per $1,000 of assessed value for 2025, representing a slight increase from 2024's rate of $15.57. Property assessments in Massachusetts are conducted at fair market value without assessment caps, meaning your property tax bill reflects current market conditions and local spending decisions made by your municipal government.

Pro tip: If you pay through mortgage escrow, your lender splits these payments across your monthly mortgage. If you pay directly, set calendar reminders to avoid late penalties.
Section 4

Supplemental Tax Bills

Supplemental property taxes in Norfolk County are triggered when significant improvements or construction add substantial value to your property during the tax year. The primary trigger occurs when construction or improvements add more than 50% to the fair market value of the existing property. This threshold ensures that major additions, renovations, or new construction are properly assessed and taxed in the year the improvements are completed.

When supplemental taxes apply, the Norfolk County Registry of Deeds coordinates with local assessors to calculate the additional tax based on the increased assessed value. The supplemental tax is prorated based on the portion of the tax year remaining after the improvement is completed and occupancy permits are issued. For example, if you complete a $200,000 addition to a $300,000 home in January, triggering the 50% threshold, you would receive a supplemental bill for the additional assessed value multiplied by your municipality's tax rate, prorated for the remaining months of the tax year.

Escrow & Property Taxes

Most mortgage lenders in Norfolk County require property tax escrow accounts to ensure timely payment of property taxes. Your lender collects monthly escrow payments as part of your mortgage payment, typically calculated by dividing your annual property tax bill by 12 months, plus a cushion amount allowed by federal regulations. The lender maintains these funds in a separate escrow account and makes payments directly to your municipality when taxes are due.

Property tax payments in Norfolk County municipalities typically follow quarterly schedules, with common due dates being September 30th for the first quarter and December 5th for the second quarter, though specific dates vary by municipality. Your mortgage servicer will coordinate payment timing with local requirements. You should receive an annual escrow analysis statement showing how your payments were applied and any adjustments needed for the coming year. If your property taxes increase due to reassessment or rate changes, your monthly escrow payment will be adjusted accordingly, typically with 60 days notice from your lender.
