The statutory assessment date in Maine is April 1st. The Assessor’s Office must retain this ownership information until April 1st of the following year. If you purchased your property after April 1st, the previous owner’s name remains on the tax bill. Every effort is made to forward tax bills to the new owner. However, if you have not received a tax bill by July 15th you should contact the Tax Collector’s Office at (207) 353-2561.
