Middlesex County is the second most populous county in New Jersey, anchored by Edison, Woodbridge, New Brunswick, and Piscataway. It has a large South Asian population, a significant research and pharmaceutical corridor, and a mix of longtime homeowners and newer families navigating NJ’s complex property tax system. Here’s what Middlesex County residents need to know about their tax deductions in 2025.
Property Taxes in Middlesex County
Middlesex County property taxes are moderate by New Jersey standards — lower than Bergen, Essex, and Monmouth, but still well above the national average. Average bills in Edison range from $9,000 to $13,000; in Woodbridge, $7,500 to $11,000; in Piscataway, $8,000 to $12,000. Many Middlesex homeowners are right at or just above the federal $10,000 SALT cap.
Because NJ state income taxes eat into a significant portion of the SALT cap, homeowners whose state income tax alone is $5,000–$8,000 may only have $2,000–$5,000 of their SALT cap left for property taxes — even though they’re paying $10,000+ in property taxes annually.
On the New Jersey return, the NJ-1040 property tax deduction (up to $15,000) applies in full regardless of the federal SALT cap — providing meaningful additional state relief. File the NJ property tax deduction on your NJ-1040, Line 38.
Edison and Woodbridge: Large South Asian Community Tax Considerations
Edison and the surrounding areas have a large Indian-American and South Asian population, many of whom are employed in tech, pharmaceuticals, and healthcare. Several tax situations are especially common in this community:
- H-1B and dual-status taxpayers: If you became a resident alien during 2025 (the year you passed the substantial presence test), you’re a dual-status taxpayer with specific filing requirements. Your deductions are limited in the non-resident period. Consult a CPA familiar with dual-status and treaty returns.
- Foreign income and FBAR: Residents with financial accounts or income in India or other countries may have FBAR (FinCEN 114) and Form 8938 reporting requirements. These are not deductions but critical compliance obligations.
- Charitable contributions: Donations to qualifying US charities (including some temples, mosques, and community organizations) are deductible on Schedule A if you itemize. Foreign charitable organizations generally don’t qualify.
New Brunswick: Rutgers University Area Deductions
New Brunswick’s economy is anchored by Rutgers University and a major pharmaceutical presence (Johnson & Johnson is headquartered nearby). Taxpayers in this area commonly have situations involving:
- Student loan interest: Graduates and grad students with federal or private loans can deduct up to $2,500 in student loan interest per year as an above-the-line deduction — no itemizing required. See the student loan interest deduction page.
- Education and professional development: Rutgers employees and researchers paying out-of-pocket for continuing education, certifications, or professional development can deduct these if self-employed. See the education deduction guide.
- Pharmaceutical and biotech 1099 contractors: Contract workers for NJ’s large pharma sector frequently have significant deductible business expenses including home office, equipment, professional software, and business travel.
Piscataway and South Plainfield: Remote Work Deductions
Many Middlesex County residents who commuted to New York, Philadelphia, or central NJ office parks shifted to full or partial remote work. For those who are self-employed or have a side business, the home office deduction is particularly relevant given housing costs.
Middlesex County’s median home value is roughly $450,000–$550,000 — lower than Bergen or Monmouth, but still high enough that the actual expense method of the home office deduction almost always produces a higher deduction than the $5/sq ft simplified method. Use the home office calculator to compare both methods for your specific situation.
ANCHOR Benefit for Middlesex County
Middlesex County homeowners and renters are eligible for the NJ ANCHOR program. The benefit amounts are the same statewide: $1,500 for homeowners earning under $150,000, $1,000 for homeowners earning $150,000–$250,000, and $450 for renters earning under $150,000.
