About the Hillside Property Market
Hillside is a city located in Union County, New Jersey. Every property inside the Hillside city limits is assessed by Union County Board of Taxation, which applies New Jersey property tax rules uniformly across the county.
Because Hillside property values are set at the county level, the $410,000 county median home value and 2.6% effective tax rate apply to homes throughout the city. Homeowners who believe their Hillside home is over-assessed have the right to file a appeal directly with Union County Board of Taxation before the April 1 deadline.
New Jersey allows the assessor to defend or adjust the assessed value during a appeal, so Hillside homeowners should build a strong evidence-based case before filing — which is exactly what ProtestMax generates for $45.
Hillside Property Market Context
The property tax picture in Hillside is shaped as much by New Jersey statewide policy as by anything unique to a city.
New Jersey market character
New Jersey has the highest effective property tax rate in the country at around 2.2%, and towns revalue on irregular schedules. Neighboring homes can have wildly different assessed-to-market ratios, making equity-based appeals particularly powerful.
How New Jersey handles appeals
New Jersey homeowners appeal to the county Board of Taxation, then the state Tax Court. Judgments under the Chapter 123 corridor create a clear statistical framework for winning cases.
When to file in Hillside
Appeals to the county Board of Taxation are due by April 1 (May 1 in reassessment years). The 25-day window after notice mailing is strict.
