Assessments and Commitment

Each year the Assessing Department reviews properties for any changes and finalizes assessments for the Fiscal Year; there are certain dates that property owners should bear in mind, which can vary in some counties and municipalities: 

  • The statutory Assessment Date in Maine is April 1st. The assessment of your property, reflected in your tax bill, is based on what existed on April 1st.

Please note: any ownership changes, applications for current use or exemption programs, or any improvements made after April 1st will not change the tax bill; changes, if any, will be reflected in the
following tax year based on the next April 1st date. Once assessments are finalized, the tax lists are
sent to the Tax Collector to be processed for billing; this annual process is called “commitment.”

  • The Commitment Date is the date when the Assessor commits the town’s assessment roll to the Tax Collector to allow for receipt of payment. Scarborough’s tax commitment generally occurs in August.

2023-2024 Tax Commitment

FY 2023-2024 assessments were committed on August 16, 2023. The mill rate is $15.97 per $1,000 valuation for taxes due on October 16, 2023 and March 18, 2024.

Although 2023 assessments have been finalized, property owners are always welcome to review their property record and reach out to us with any questions; visit Vision Online Database to view and download a PDF of your Property Card (a/k/a Field Card); however, you may first want to view our step-by-step "How to Find Your Property Card" guide for more details. When you locate your property card, you should review it carefully. See our How to Interpret Your Property Card visual guide explaining each section of the card.

To learn more about the process for determining the 2023-2024 tax rate, please see "2023-2024 Tax Rate Set". 

The Assessor will deliver a brief presentation regarding the Tax Commitment at the Town Council Workshop scheduled for September 6th, 2023.
