Appealing a Union Township (Union County) assessment
New Jersey appeals go to the Union County Board of Taxation. The petition is due April 1, or May 1 in a year when Union Township (Union County) implemented a municipal-wide revaluation or reassessment (NJ Division of Taxation). Property assessed above $1,000,000 may go directly to the Tax Court, and a County Board judgment can be appealed to the Tax Court within 45 days.

Using the 9.73% ratio implied by the state's two rates, that range runs from about 8.27% to 11.19% of market value; the Director's official average ratio for Union Township (Union County), which the County Board applies, can differ slightly.
