The Town of Washington Assessor’s Office is responsible for maintaining the assessment roll for both the Town of Washington and the Village of Millbrook. The assessment roll establishes the base value from which property taxes are levied. New York State law requires the assessor to maintain assessments at a uniform percentage of market value each year. Paramount to the successful completion of the assessment roll is the careful maintenance of property record cards. Each parcel within the Town of Washington has an individual property record card noting ownership, inventory, and a sketch of structures.

The town conducted a property revaluation in 2005-2006 and currently assesses at 100% market value. Participation in a five year assessment program is required by the State of New York in order to maintain full market value status. It is necessary to review 20%, or approximately 500 parcels, annually to ensure the validity of property values. These reviews are conducted by site visits and the analysis of property inventory. Additionally, the assessor along with representatives from the New York State Office of Real Property Services, reviews sales trends and may determine that all property values need a percentage adjustment in order to accurately reflect true market value. Market value is the primary consideration for establishing assessed value, but an inter-comparison between the assessments of similar properties is also of significant importance.

The assessor’s office also works in conjunction with the building departments of the Town of Washington and the Village of Millbrook to carefully monitor new construction as well as property enhancements and changes. Building permits and plans are submitted to the assessor and property record cards are updated after site visits called “road reviews” are performed each fall. Changes made to properties in the previous year may affect the properties assessed value.

It is vital that property owners periodically review the inventory attributed to their properties to ensure accuracy. It is the responsibility of the individuals to monitor their assessments especially after the tentative roll is filed. The assessor is available for consultations regarding individual parcels and can provide information regarding assessments. However, the assessor does not set tax rates and cannot provide information regarding the policies of the individual taxing bodies which include local school districts, Dutchess County, the Town of Washington and special districts and the Village of Millbrook and special districts.

Assessment Grievances

If a property owner is not satisfied with their assessment they may file a grievance with the Board of Assessment Review (BAR). Grievance Day is held on the 4th Thursday in May each year. The BAR is a body of citizens who live in the town. Their purpose is to listen to the grievances of property owners and possibly make changes to the assessments. The burden is on the property owner to prove that the filed property assessment is excessive, unequal, or unlawful. If individuals are not satisfied with the determination of the BAR, they can elect to appeal to Small Claims Assessment Review (SCAR) or initiate an Article 7 certiorari proceeding in State Supreme Court.
