Supplementary/Omitted Tax Billings
Property Assessment Change Notices are issued for additional assessment (such as swimming pools, decks or other additions), new homes or property class changes. The property tax dollars associated with the changes are retroactive to the date of occupancy / purchase, or when the renovation or alterations were completed.
Please note the Municipal Property Assessment Corporation (MPAC) assesses your property for the additional assessment, a new home or a property class change which could take up to three years to occur.
The Town issues your supplementary/omitted tax bill(s) and payments are typically due in two installments. Depending on the determined assessment, the additional property taxes may be in the thousands of dollars. The Town may be able to assist in preparation for the imminent supplementary/omitted tax bill(s) to minimize the impact of this bill. Please contact the Customer Service Department for additional information and assistance.
