Bills are sent to the address of the last known owner by state law. The Tax Assessor’s Office updates its records according to the transfer recorded and received from the Coos County Registry of Deeds. Your attorney or closing company should have checked the status of taxes due. However, it is your responsibility as the owner to make sure they are paid and to advise us of your mailing address in writing. If you have questions about this, refer to your closing statement and/or give us a call. Interest at 12% per annum is charged on tax bills not paid by the due date. Also, interest at 18% per annum is charged on tax liens until paid in full.
