Tax Liens

Tax liens for non-payment are placed in August following the August commitment date. Tax liens mature 18 months later resulting in automatic foreclosure by State Law. Tax liens may affect your credit rating.

The town accepts partial payments on taxes at any time with one exception during mid-July to mid- August during the tax lien process. At that time, payments on current taxes must be made in full. In addition, payments during that time must be cash or bank checks only. Throughout the rest of the year, the Town encourages taxpayers to make partial payments if it is helpful to them. If you would like to set up a payment plan, please contact the Tax Collection Office at 207-892-2511.
