New Jersey has one of the most complex state income tax systems in the country. Its graduated rates reach 10.75% on income above $1 million - but New Jersey does not tax Social Security benefits and provides a substantial retirement income exclusion for qualifying taxpayers. New Jersey also imposes an inheritance tax (not an estate tax) on transfers to non-immediate family members at rates up to 16%. New Jersey's ANCHOR property tax relief program and Senior Freeze provide significant direct payments to qualifying homeowners and renters. Understanding all the layers - income tax, inheritance tax, property tax relief, and the NJ PTET election - requires a state-specific analysis that federal planning alone does not address.
Income tax rates: 1.4% (up to $20,000), 1.75% ($20,001-$35,000), 3.5% ($35,001-$40,000), 5.525% ($40,001-$75,000), 6.37% ($75,001-$500,000), 8.97% ($500,001-$1,000,000), 10.75% (above $1,000,000).
No Social Security tax: New Jersey does not tax Social Security benefits, regardless of total income.
Retirement income exclusion: Taxpayers with gross income of $100,000 or less may exclude up to $100,000 of pension, annuity, and IRA income (married filing jointly; $75,000 single). The exclusion phases out as income exceeds the threshold.
No NJ estate tax: New Jersey repealed its estate tax effective January 1, 2018. But the inheritance tax remains in effect.
While New Jersey no longer has an estate tax, it retains an inheritance tax on transfers to certain beneficiaries. Class A beneficiaries (spouse, domestic partner, civil union partner, children, grandchildren, parents, stepchildren) pay no inheritance tax. Class C beneficiaries (siblings, sons/daughters-in-law) pay 11-16% on amounts above $25,000. Class D beneficiaries (all others - nieces, nephews, friends, non-married partners) pay 15-16% on all amounts transferred. Class E (nonprofit organizations, government entities) pays no tax. A New Jersey resident who leaves $500,000 to a sibling owes significant NJ inheritance tax even though no NJ estate tax or federal estate tax applies.
New Jersey's treatment of pension income differs from federal and most state treatments because it depends on the source of the pension and whether New Jersey income tax was withheld from contributions. Government pensions: New Jersey, federal, and most state government pensions are generally not taxable to the extent contributions were made with after-New Jersey-tax dollars (which is the case for most NJ public employee pensions). Private pensions and IRA distributions: taxable under New Jersey rules, subject to the retirement income exclusion for qualifying taxpayers. New Jersey does not conform to the federal rollover rules exactly - NJ taxpayers who made non-deductible IRA contributions for New Jersey purposes have a different NJ basis than their federal basis.
New Jersey offers direct property tax relief through two programs. The ANCHOR program (Affordable New Jersey Communities for Homeowners and Renters) provides annual benefits to homeowners (up to $1,500) and renters (up to $450) based on income. The Senior Freeze (Property Tax Reimbursement) reimburses senior and disabled residents for increases in property taxes above their base year tax, provided they meet income limits and have been NJ residents for at least 10 years. These are direct payment programs, not deductions, and require separate annual applications.
