What the rule says
New Jersey imposes a state inheritance tax under N.J.S.A. 54:34-1 et seq. on transfers at death from a New Jersey decedent. Like Pennsylvania (covered in pa_inheritance_tax_rate_schedule), NJ imposes the tax on the recipient based on relationship to the decedent — not on the estate as a whole.
Under the NJ framework, recipients fall into classes:
- Class A (0% tax): Surviving spouse, civil union partner, domestic partner, children (including adopted), grandchildren, great-grandchildren, parents, grandparents, and stepchildren - Class C (11-16% tax, with $25,000 exemption): Brothers, sisters, sons-in-law, daughters-in-law - Class D (15-16% tax): All other beneficiaries — friends, more distant relatives, charitable beneficiaries that don't qualify for the Class E exemption - Class E (0% tax): Qualifying charitable, religious, educational organizations and the federal/state government
Notably, stepchildren ARE Class A in New Jersey — different from Pennsylvania (where unadopted stepchildren are 15% Class). This is one of NJ's distinctive features.
Class C and D rate schedules
Class C (siblings, in-laws) — first $25,000 exempt, then: - 11% on next $1,075,000 - 13% on next $300,000 - 14% on next $300,000 - 16% on excess over $1,700,000
Class D (other recipients) — no exemption: - 15% on first $700,000 - 16% on excess over $700,000
The class structure produces sharply different tax outcomes: - $500,000 to a child (Class A): $0 tax - $500,000 to a sibling (Class C): $52,250 tax (after $25,000 exemption) - $500,000 to a friend (Class D): $75,000 tax
NJ estate tax was eliminated
New Jersey previously had both an estate tax and an inheritance tax. The estate tax was eliminated effective January 1, 2018 — for decedents dying on or after that date, no NJ estate tax applies. The inheritance tax remains in effect.
This is meaningful national context. NJ is now in a distinctive position: - No estate tax (eliminated 2018) - Inheritance tax remains for non-Class A beneficiaries - Federal estate tax applies to estates above the federal exclusion (~$13.99M in 2026)
What is included in the inheritance tax base
New Jersey's inheritance tax has a broad reach, including most transfers at death:
- All probate property - Revocable trust property - Joint accounts (decedent's contribution) - Beneficiary designation transfers - Pension and retirement benefits (with specific rules)
Life insurance is generally exempt under N.J.S.A. 54:34-4 when payable to a beneficiary other than the estate.
What this means in practice
The class-based structure produces several distinctive NJ planning patterns:
- Class A includes children, grandchildren, AND stepchildren. This is more inclusive than Pennsylvania's Class A. Bequests to stepchildren — adopted or not — face 0% tax in NJ. - Sibling and in-law bequests are expensive. $1 million to a sibling produces ~$135,000 of NJ inheritance tax (after $25,000 exemption). - Bequests to friends or distant relatives are highly taxed. $1 million to a friend produces $147,000 of NJ inheritance tax (15% on first $700K, 16% on remaining $300K). - Charitable bequests are tax-efficient. Class E (qualifying charities) face 0% tax. - Life insurance is uniquely tax-efficient. Life insurance to non-Class-A beneficiaries faces 0% inheritance tax (similar to Pennsylvania).
Filing requirements
NJ inheritance tax requires specific procedures:
- Returns are due 8 months after the decedent's death. A waiver of the New Jersey inheritance tax is required before financial institutions release certain assets. - The Director of Taxation administers the tax. Filings are made with the New Jersey Division of Taxation. - Bank waivers. New Jersey banks generally require an inheritance tax waiver before releasing significant funds to non-Class-A beneficiaries.
What you can do about it
For NJ residents:
- Recognize the class-based structure. Plans should account for differing rates by intended beneficiary. - Use Class A exemption for primary beneficiaries. Spouse, children, stepchildren, parents — all 0%. - Consider charitable bequests. Class E exempt. - Use life insurance for non-Class-A beneficiaries. Substantial tax efficiency. - Coordinate beneficiary designations. Direct life insurance and retirement accounts strategically.
For NJ residents with substantial wealth:
- NJ has no estate tax. Estate planning focuses on inheritance tax planning. - Federal estate tax applies above $13.99M. Coordinate with federal planning. - Domicile considerations. Florida, Texas (no inheritance tax) eliminate NJ inheritance tax exposure if domicile is properly established.
Who this affects most
NJ inheritance tax is most consequential for:
- NJ residents with bequests to siblings, in-laws, friends, or distant relatives - Estate planners coordinating beneficiary designations with class-based tax outcomes - High-net-worth NJ residents at federal estate tax thresholds - Snowbirds considering NJ-Florida domicile changes
NJ's class-based inheritance tax framework is distinctive nationally. The combination of broad Class A (including stepchildren) and the elimination of the estate tax produces a different planning landscape than other inheritance tax states like Pennsylvania.
