The Warren County Assessment Office is primarily responsible for the valuation of real property for ad valorem (at value) tax purposes, including the management of all property characteristics and ownership records.  This office does not establish the real estate tax levy; it is responsible for the valuation (commonly known as the assessment) of all real property in Warren County.

Based on those assessments, the County, municipalities, and school districts establish budgets and necessary millage rates to generate revenue, apply those millage rates to individual property assessments, thereby producing individual property tax levies.

The Assessment Office also administers the Homestead and Farmstead Program (Act 50 & Act 1), the Clean and Green Preferential Assessment Program (Act 319) , creates and maintains all mapping including GIS (geographical information system) mapping and creates and maintains all addressing for the E911 numbering system for new construction.

The office is further responsible for the production of tax duplicates, resulting in the preparation and delivery of County and municipal real estate tax notices for the 21 townships, 5 boroughs and 9 city wards in Warren County.

The County’s last reassessment was completed in 1989.  The real estate assessments represent 50% of 1989 market values.
