- NJ does allow a property tax deduction (up to $15,000 assessed value basis)
- NJ does have its own medical expense deduction rules
- Business deductions largely mirror federal rules under NJ gross income tax

NJ Property Tax Deductions & the ANCHOR Program
New Jersey has the highest property taxes in the country — averaging over $9,000 per year. Here’s how to reduce your burden through deductions and state benefit programs.
Property Tax Deduction (State Return)
On your NJ state income tax return, you can deduct property taxes paid on your principal residence — up to $15,000 in assessed value. The actual tax deduction amount depends on your local tax rate.
Explore Home Deductions →ANCHOR Property Tax Benefit
The ANCHOR (Affordable New Jersey Communities for Homeowners and Renters) program provides direct rebate checks to eligible NJ homeowners and renters. Homeowners can receive up to $1,750; renters up to $700. Apply through the NJ Division of Taxation.
ANCHOR Program Info →Federal SALT Deduction
On your federal return, you can deduct state and local taxes (SALT) including NJ property taxes and state income taxes — but only up to $10,000 total. Most NJ homeowners hit this cap quickly given NJ’s high property taxes.
Learn More →Senior Freeze (PTR)
NJ seniors and disabled residents may qualify for the Property Tax Reimbursement (Senior Freeze) program, which reimburses the difference between current and base-year property taxes. Age 65+ or receiving federal Social Security disability benefits required.
