The town assessor has the responsibility for maintaining an accurate inventory of town properties and their taxable value. All real estate - including vacant land - is assessed. The assessment process is designed to ensure that each property owners pays a fair share of taxes levied by the town of Patterson, Putnam County, and the appropriate school district. The town of Patterson assesses at 100% of current market value.

The assessor does not set the tax rates. Town tax rates are set by the Patterson Town Board and Putnam County taxes are set by the County Executive and the County Legislature. School tax rates are set by the school districts (Carmel, Brewster, and Pawling).

Building permits and demolition permits may sometimes be required for work done on your property. The permit process provides a way for the building inspector to notify the assessor that a change in the taxable value of the property may be needed. For example, a demolition permit to remove a deck will notify the assessor that the taxable value of the property can be reduced by the taxable value of the deck. A building permit to add a bedroom will, on the other hand, notify the assessor that the value of the property has been increased because the square footage of the house has increased.

Property owners have the responsibility for monitoring their assessments and assuring the accuracy of the assessment. The most common way to do this is to determine whether the property description, known as the inventory, is correct. For a residence, an example of things to verify would include the number of bedrooms, number of bathrooms, square footage of structures, and size of the lot. Property owners may make an appointment with the Assessor or the Assessor's Staff to discuss any discrepancies or assessment concerns. If the homeowners are still not satisfied, they may file a formal grievance by completing application RP-524 with their supporting evidence attached. The application and evidence must be submitted to the Board of Assessment Review by the fourth Tuesday in May.

The assessor works closely with the Putnam County Department of Real Property Services which maintains a computerized list of all properties in the County. The assessor is appointed by the Town Board.
