New Jersey SALT Deduction Calculator 2026

New Jersey residents face some of the highest combined tax burdens in the United States, driven primarily by the highest property taxes in the nation. The old $10,000 SALT cap was particularly punishing for New Jersey homeowners, many of whom pay more than $10,000 in property taxes alone before even counting state income taxes.

New Jersey's Record-High Property Taxes

New Jersey has the highest average effective property tax rate in the country at approximately 2.23%. The median annual property tax bill in New Jersey exceeds $9,000, and many homeowners in Bergen, Essex, Passaic, and Union counties pay $12,000 to $18,000 or more per year. Under the old $10,000 SALT cap, many New Jersey homeowners could not even deduct their full property tax bill, let alone their state income taxes.

New Jersey State Income Tax

New Jersey's state income tax has rates ranging from 1.4% to 10.75%. The top rate of 10.75% applies to income over $1 million. For a typical household earning $175,000, a state income tax bill of $5,000 to $8,000 is common. Combined with property taxes, total SALT easily reaches $15,000 to $25,000+ for middle-class and upper-middle-class families.

Worked Example: NJ Couple Earning $175,000

Consider a married couple in New Jersey earning $175,000 combined:

• NJ State Income Tax: ~$7,000
• Property Tax: ~$12,500
• Total SALT: $19,500

Under the old $10,000 cap, they could only deduct $10,000 of their $19,500 in SALT payments. Under the new $40,400 cap, they can deduct the full $19,500. That's an additional $9,500 in deductions. At the 22% federal tax bracket, this translates to approximately $2,090 in annual tax savings.

Why New Jersey Residents Benefit Significantly

Because New Jersey's property taxes are so high, nearly every homeowner in the state was limited by the old $10,000 SALT cap. The increase to $40,400 means most New Jersey homeowners can now deduct their full property tax bill plus their state income taxes. This is especially impactful in suburban counties where property values and tax rates are both high, creating property tax bills that alone exceed the old cap.
