Payment options & deadlines

The City of Boston accepts electronic payments through its official payment portal and lists accepted methods and instructions on its Assessing and Treasury pages. Payment deadlines for property tax installments or single bills are printed on each tax bill; the city site advises taxpayers to check their mailed or electronic bill for the exact date. Specific schedule dates are not specified on the cited City pages and are shown on individual bills or billing notices.[1][2]

Check your property tax bill for the exact due date and bill number before paying online.

Penalties & Enforcement

The City of Boston identifies the Treasury Division as the office responsible for tax collection and enforcement. Official City pages describe the collection process but do not list exact fine amounts or interest rates on the municipal payment pages; those numeric penalties are not specified on the cited City pages.[2]

  • Monetary penalties: interest and late charges are applied for delinquent taxes — exact percentages or flat fees are not specified on the cited pages.
  • Escalation: continued nonpayment may lead to liens or collection actions; the City pages do not provide a step-by-step fine schedule.
  • Non-monetary remedies: tax liens, possible sale/foreclosure processes under applicable law are referenced generally but exact procedures and timelines are not detailed on the cited City pages.
  • Enforcer: Treasury Division (City of Boston) handles billing, collection and inquiries; contact information is available on the Treasury page.[2]
  • Appeals and review: assessment disputes and requests for abatement go through the Assessing Department; time limits and form requirements are listed on the Assessing abatement page or on the bill itself.[1]
If you cannot pay by the due date, contact the Treasury Division immediately to discuss options.

Applications & Forms

The City maintains an Assessing abatement application and instructions for contesting assessed values; form names and submission steps are available on the Assessing Department pages. If a specific form number, fee or filing deadline is not shown on the City page, it is not specified on the cited page; check the Assessing abatement page and your tax bill for exact filing deadlines and requirements.[1]

How collections work and taxpayer remedies

When a tax becomes delinquent the Treasury Division initiates collection steps. Taxpayers may request abatements for incorrect assessments, seek payment plans if offered, or appeal assessments through the Assessing Department procedures. Documentation and timely filing are essential for appeals; if deadlines are omitted on the web page, they will be printed on the tax bill or specified in the abatement instructions.[1][2]
