How Property Tax Works

Plymouth County operates under Massachusetts' property tax system, where property taxes serve as the primary funding mechanism for local services including schools, police, fire protection, public works, and municipal operations. The county encompasses 27 cities and towns, each setting their own tax rates based on local budgets and state-mandated assessments. Property owners can expect effective tax rates typically ranging from approximately 1.0% to 1.4% of assessed value, though this varies significantly by municipality within the county.

Massachusetts operates under Proposition 2½, a statewide property tax limitation that restricts annual tax levy increases to 2.5% plus new growth, with total taxes generally capped at 2.5% of total assessed value. However, actual rates paid by individual property owners within Plymouth County vary considerably based on their specific municipality and any special taxing districts that may apply to their property, such as school districts, water districts, or local improvement districts.

The assessment date is January 1st each year, which freezes the ownership, physical condition, and characteristics of each property for determining the following fiscal year's valuation. All property tax obligations are based on ownership as of this critical date.

Important Note: Tax rates vary significantly among Plymouth County's 27 municipalities. Each city and town sets its own rate based on local budget requirements. Additionally, special taxing districts within municipalities can create rate variations even within the same city or town. Property owners should verify their specific municipal rate and any applicable special district assessments with their local assessor's office.

When Are Property Taxes Due?

For the 2025/2026 tax year in Plymouth County, property taxes are due in two installments:

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 taxes in Plymouth County are triggered by specific events that change a property's assessed value or ownership during the tax year. The primary triggers include ownership changes (sales or transfers), new construction completion, major renovations that increase property value, and subdivision of property. These assessments ensure that tax obligations reflect current property values and ownership throughout the fiscal year.

Supplemental taxes are calculated based on the difference between the old assessed value and the new assessed value, multiplied by the applicable tax rate, and prorated for the portion of the tax year remaining after the triggering event. For example, if a property's assessed value increases from $400,000 to $500,000 due to completed renovations on January 1st, and the local tax rate is $12.55 per $1,000, the supplemental tax would be calculated on the $100,000 increase for the full fiscal year.

County taxes related to supplemental assessments are typically due on the subsequent November 1st and May 1st, following the standard quarterly payment schedule. Property owners receive separate billing for supplemental assessments, and these amounts are in addition to the regular quarterly tax bills.

Escrow & Property Taxes

Most mortgage lenders in Plymouth County require property tax escrow accounts for borrowers with less than 20% down payment, though some lenders may require escrow regardless of down payment amount. The lender collects monthly payments equal to 1/12th of the estimated annual property tax bill and holds these funds in a dedicated escrow account. When tax bills become due, the lender pays the taxes directly to the appropriate municipal tax collector.

Property taxes in Plymouth County are billed quarterly with due dates of August 1st (1st quarter), November 1st (2nd quarter), February 1st (3rd quarter), and May 1st (4th quarter). Lenders typically pay these bills shortly before the due dates to avoid late penalties. Property owners should receive annual escrow statements showing all deposits, payments, and account balances, usually provided after the end of the lender's fiscal year.

Homeowners with escrow accounts should monitor their property tax bills for accuracy and notify their lender immediately of any discrepancies. When property values change significantly due to reassessment or home improvements, escrow payments may need adjustment. Lenders are required to analyze escrow accounts annually and adjust monthly payments accordingly, though they may spread deficiencies over 12 months while requiring immediate payment of surpluses exceeding certain thresholds.

All credits require annual application and are not automatic. Applications must be filed by April 1st.

Q: How does the Homestead Credit work? A: The Homestead Credit does not reduce your property's assessed value. Instead, it caps annual assessment increases to provide stability in property tax bills. You must file an application to receive this protection - it is not automatic.

Q: What happens if I pay my property taxes late? A: Late payments incur interest charges and penalties. Interest typically accrues from the due date until payment is received. Continued non-payment can eventually lead to tax lien procedures.

Q: Can I pay property taxes online? A: Online payment options vary by municipality within Plymouth County. Contact your local tax collector's office or visit your city/town website to determine available electronic payment methods.
