Property Tax in Union County

via TaxByCounty

Union's rate outpaces most U.S. counties

Union County's effective tax rate of 2.05% nearly doubles the national median of 0.95%, placing it in the top 25% of counties for property tax burden. The median tax bill of $10,001 is 272% above the national median of $2,690, driven by Union's high home values of $488,800.

Slightly below state average for NJ

Union County's effective rate of 2.05% falls slightly below New Jersey's state average of 2.21%, making it one of the state's more favorable tax environments. However, the median tax bill of $10,001 exceeds the state average of $8,512 due to Union's above-average property valuations.

The lowest rate among peers

Union's 2.05% effective rate is the lowest among comparable regional counties—Warren (2.52%), Sussex (2.47%), and Salem (3.03%). Only Somerset (1.91%) offers a more favorable tax rate in this geographic area.

A $488,800 home costs $10,001 yearly

The median Union County home valued at $488,800 generates an annual property tax bill of $10,001. Both mortgage holders and outright owners pay the same amount, indicating standardized assessment practices throughout the county.

Union County homeowners should verify assessments

With some of the state's highest home values, Union County properties occasionally carry inflated assessments that don't reflect actual market conditions. Filing a tax appeal is free and can reduce annual bills, especially for properties that may be overvalued.

Union bridges the income middle ground

Union earns $50,843 less than Somerset but $5,521 more than Warren County, positioning it as a bridge between New Jersey's wealthiest and more modest-income regions. This income level reflects Union's role as a commercial and residential hub in the state's northeastern corridor.

Housing costs present affordability challenge

Union's 19.9% rent-to-income ratio is the highest among these five counties, signaling early affordability stress for renters. The median home value of $488,800 requires substantial household income to afford comfortably, demanding careful financial planning.

Plan strategically amid higher housing costs
