Union County sits at the crossroads of New Jersey — geographically central, economically diverse, and home to one of the most varied property tax landscapes in the state. Within a 10-mile radius you have some of NJ’s highest-tax, most sought-after suburbs (Summit, Westfield, New Providence) and some of its most economically distressed cities (Elizabeth, Plainfield, Roselle). This guide covers the key tax issues, programs, and strategies for Union County residents in 2025.
Union County Property Taxes: Wide Variation
| Municipality | Avg. Annual Property Tax | Notes |
|---|---|---|
| Summit | ~$17,500 | Premium commuter suburb; top schools |
| Westfield | ~$16,200 | NJ Transit hub; high demand |
| New Providence | ~$13,800 | Strong schools; mid-county location |
| Cranford | ~$12,600 | Popular with young families; commuter-friendly |
| Scotch Plains | ~$12,100 | Large, varied housing stock |
| Fanwood | ~$11,800 | Smaller borough; Raritan Valley Line |
| Elizabeth | ~$8,100 | NJ’s 4th largest city; urban core |
| Plainfield | ~$9,400 | High rate on moderate values |
| Roselle | ~$8,700 | Industrial heritage; high effective rate |
| Linden | ~$8,500 | Industrial city; diverse economy |
ANCHOR Benefits for Union County Residents
Union County households at or below $250,000 in income qualify for ANCHOR. Given the income diversity across the county, eligibility rates vary significantly by town:
- In Elizabeth, Plainfield, and Roselle — most homeowners and renters qualify for the full $1,500 or $450 benefit
- In Westfield and Summit — many households exceed the $250,000 ceiling and don’t qualify
- In Cranford, Scotch Plains, and Springfield — a significant share of homeowners fall in the $150,001–$250,000 range and receive $1,000
Union County renters in Elizabeth, Hillside, Roselle Park, and Kenilworth should make sure to apply — the $450 renter benefit is often overlooked, and renter application rates are historically lower than homeowner rates.
Elizabeth: Urban Enterprise Zone and Tax Advantages
Elizabeth is one of NJ’s designated Urban Enterprise Zone cities. The UEZ designation provides:
- Half-rate sales tax (3.3125%) for purchases made at UEZ-registered businesses — a meaningful benefit for businesses and shoppers in the zone
- Business incentives including employment tax credits for hiring qualified employees from within the UEZ
- Lower effective costs for businesses operating within the zone versus surrounding areas
Elizabeth’s port activity, retail presence, and proximity to Newark Liberty Airport make it a hub for logistics, warehousing, and small business activity. Businesses in the Elizabeth UEZ should verify their qualification for half-rate sales tax collection with the NJ Division of Taxation.
Summit and Westfield: NYC Commuter Premium
Summit and Westfield are two of NJ’s most desirable commuter towns — direct NJ Transit service to Penn Station (Summit via the Morris & Essex Line; Westfield via Raritan Valley Line with connecting service) drives premium home values and property taxes. For residents commuting to NYC:
- File NJ-1040 (resident) and NY IT-203 (nonresident) for income earned in NY
- Claim NJ resident credit for taxes paid to NY — reduces but doesn’t eliminate double taxation
- Track remote work days from Summit or Westfield home carefully — those days are NJ-sourced income
- Hybrid work arrangements (2–3 days in NYC, rest at home) can meaningfully reduce your NY income tax exposure and increase the share taxed only by NJ
Self-Employed and Business Owners in Union County
Union County has a significant population of independent professionals and business owners, particularly in healthcare, retail services, and logistics. NJ-specific rules that affect self-employed Union County residents include the lack of a state-level health insurance deduction and NJ’s own depreciation schedule (no bonus depreciation). See our NJ self-employed tax guide for the full picture.
Property Tax Appeals in Union County
The Union County Board of Taxation handles appeals for properties assessed under $1 million. Given rapid price appreciation in Westfield, Summit, Cranford, and New Providence since 2020, many homeowners’ assessments haven’t caught up with current market values — meaning some are overassessed relative to comparable sales. The appeal deadline is April 1. Evidence required: recent comparable sales (comps) within your neighborhood showing market values lower than your assessment.
NJ Deductions Union County Residents Commonly Miss
- Property tax deduction on NJ-1040 — deduct up to $15,000 of property taxes paid on principal residence against NJ taxable income
- Renter deduction (18% of rent) — renters in Elizabeth, Plainfield, Roselle Park, and Kenilworth should claim this on their NJ-1040
- NJ Earned Income Tax Credit — 40% of federal EITC; many Elizabeth, Plainfield, and Roselle workers qualify at the full benefit level
- Child and dependent care credit — up to $900 for families with two or more qualifying young children
- Pension exclusion — retirees in Cranford, Clark, Springfield, and other suburban towns should verify income eligibility annually
