Due Dates

Property tax bills are mailed in late summer. The first due date is typically September 15, and the second is November 15. Actual due dates will be posted here once decided.

Payment Plans

There is no grace period for property tax payments. You may at any time before the due date contact the Town Office to design a payment plan to spread out your tax payment over smaller installments earlier in the tax year. Once taxes are overdue, you will need to work with the Delinquent Tax Collector, who can be reached at

Delinquent Taxes - Penalty and Interest

Taxpayers who do not pay their full property tax amount by the November due date will be contacted by the Delinquent Tax Collector.

A penalty is a one-time assessment expressed as a percentage of the original amount of a tax delinquency. At Town Meeting on March 5, 2024, Calais voters set the delinquent tax penalty rate at 8%.

After each tax installment due date, and again on the first day of each month thereafter, interest on the outstanding tax balance is assessed at the monthly rate determined by the voters. At Town Meeting on March 5, 2024, Calais voters set the delinquent tax interest rate at one half of one percent (0.5%) per month or any part of a month.

If you are unable to pay your property taxes, you may be eligible to apply to the Calais Board of Abatement for a one-time abatement of part or all of your delinquent taxes, fees, and interest. See the Board of Abatement page for more information.
