NJ Inheritance Tax — Class A through E in Plain English

By Robert W. Avery, Esq.

New Jersey is one of a small number of states still imposing an Inheritance Tax. The tax is calculated based on the beneficiary’s relationship to the decedent, not on the size of the estate alone — which makes NJ’s framework structurally different from the federal estate tax most people are familiar with. The governing statute is N.J.S.A. 54:34-1 et seq.

Note at the outset: NJ also had a separate state estate tax that was repealed effective 2018. The Inheritance Tax remains. This post explains the modern Class A through E framework, who is exempt, who is taxed, the rates, the filing process, and the estate-planning implications.

How NJ Inheritance Tax Works

The tax applies to transfers from a NJ decedent at death — through a will, by intestacy under N.J.S.A. 3B:5-3 et seq., or by operation of law (joint property, beneficiary-designated assets, trusts). The tax is assessed against the bequest received by each beneficiary based on their relationship class.

A NJ Inheritance Tax Return must be filed where any tax may be due. The return goes to the NJ Division of Taxation, Inheritance and Estate Tax Branch. Where applicable, a transfer inheritance tax waiver is required to release banks, brokerages, and other custodians of decedent’s assets — without the waiver, the custodian is statutorily prohibited from releasing the property.

The Class Structure

Class	Beneficiaries	Treatment
Class A	Spouse, civil-union partner, domestic partner, child, stepchild, mutually acknowledged child, grandchild, parent, grandparent	Fully exempt
Class C	Sibling, son-in-law, daughter-in-law (surviving spouse of a deceased child)	First $25,000 exempt; tiered rates above
Class D	Anyone else (including unrelated friends, more-distant relatives, partners not formally registered)	Tiered rates from $0
Class E	Charities, public/educational/religious institutions, the federal government, the State of NJ and its political subdivisions	Fully exempt

(Class B was eliminated decades ago.)

The class structure is the controlling element. A wealthy NJ estate left entirely to Class A beneficiaries — say, a spouse and children — pays zero NJ Inheritance Tax regardless of estate value. The same estate left to nephews and nieces (Class D) faces substantial tax exposure.

Class C — Sibling and Surviving In-Law

Class C beneficiaries are siblings of the decedent and the surviving spouse of a deceased child. The first $25,000 received by each Class C beneficiary is exempt. Above that:

Bequest amount	Rate
$25,001 – $1,100,000	11%
$1,100,001 – $1,400,000	13%
$1,400,001 – $1,700,000	14%
Above $1,700,000	16%

The rates are graduated — the first $25,000 above the exemption is taxed at 11%, the next bracket at 13%, etc. The effective rate for most Class C beneficiaries (where the bequest is well within the $1.1M first bracket) is 11% on the post-exemption amount.

Class D — Anyone Else

Class D is the catch-all. Anyone not in Class A, C, or E falls into Class D. There is no exemption:

Bequest amount	Rate
Up to $700,000	15%
Above $700,000	16%

Class D therefore carries the heaviest NJ Inheritance Tax burden. A bequest of $100,000 to a friend or unrelated heir produces $15,000 of NJ Inheritance Tax. A bequest of $1,000,000 produces approximately $153,000 (15% on the first $700K, 16% on the next $300K).

Federal Estate Tax Overlay

NJ’s repealed-in-2018 state estate tax means the only estate-level tax most NJ estates face is the federal estate tax. The 2024 federal exemption is $13.61M per individual (subject to sunset reductions in 2026 absent Congressional action). Most NJ estates are well below the federal threshold and pay no federal estate tax.

The Inheritance Tax is independent of the estate tax. An estate valued at $300,000 left to nephews pays Class D Inheritance Tax (~$45,000) even though it is far below the federal estate-tax threshold.

Filing the NJ Inheritance Tax Return

The NJ Inheritance Tax Return (Form IT-R for resident decedents, IT-NR for non-resident decedents) is due 8 months from the date of death (with extension available). Pre-payment within 8 months avoids interest. A bank/brokerage waiver must be obtained through the return process to release jointly-held or solely-held assets in the decedent’s name.

For Class-A-only estates, a simplified return may apply. Where all beneficiaries are Class A, the practical effect is no tax — but the return process and waiver process still typically run.

Estate Planning Implications

The Class structure drives NJ estate planning more than the federal estate tax does for most clients. A few practical points:

Domestic partner registration

A NJ-registered domestic partner is Class A (exempt). An unregistered cohabitant is Class D (16% on amounts over $700K with no exemption). For long-term cohabitating couples without formal marriage or civil union, registering as domestic partners is one of the highest-leverage estate-planning steps.

Step-children and “mutually acknowledged” children

A stepchild is Class A. A non-step child treated as one’s own and mutually acknowledged in childhood may also qualify as Class A under N.J.S.A. 54:34-2. This is fact-specific.

Charitable bequests

Charitable Class E bequests are exempt. For an estate with mixed beneficiaries, increasing the charitable share reduces the Inheritance Tax burden across the rest of the estate.

Lifetime gifts

NJ does not have a state gift tax. Lifetime transfers from parents to children, friends, or charities reduce the size of the taxable estate at death. Federal gift-tax annual exclusion limits ($18,000/donee/year for 2024) apply.

Joint Property and Beneficiary Designations

Joint accounts, joint real estate, payable-on-death (POD) accounts, transfer-on-death (TOD) registrations, and life-insurance and retirement-plan beneficiary designations all pass outside the will but are counted for Inheritance Tax purposes if the recipient is a non-Class-A beneficiary. Estate planning that ignores beneficiary designations can produce unexpected Class D inheritance-tax exposure.

Frequently Asked Questions

Is NJ Inheritance Tax the same as Estate Tax?

No. Inheritance Tax is paid by the recipient based on relationship class. Estate Tax is paid by the estate based on size. NJ repealed its state estate tax effective 2018; the Inheritance Tax remains.

Does my spouse pay NJ Inheritance Tax?

No. Spouses, civil-union partners, and registered domestic partners are Class A and fully exempt.

What about my children and grandchildren?

Class A — fully exempt.

What about my brother or sister?

Class C. First $25,000 exempt; 11-16% on excess.

What about my nephews and nieces?

Class D. No exemption; 15-16% on the entire bequest.

What about my favorite charity?

Class E — fully exempt.

Do I have to file a return if all beneficiaries are Class A?

A simplified return process may apply. The waiver process to release jointly-held and solely-held assets typically still runs through the return.

When is the return due?

8 months from the date of death.
