In New Jersey, an unmarried partner who is not a spouse, civil union partner, or registered domestic partner pays inheritance tax of 15% to 16% on what they inherit. Couples who are both 62 or older can register an NJ domestic partnership, which makes the surviving partner exempt from the tax.
Last updated: October 2026. From the Law Firm of Benjamin D. Eckman, an elder law and estate planning firm with offices in Union, Wayne, and Hackensack, NJ.
Picture a woman who has lived with her partner for six years. They share a home and split the bills. They plan to grow old together, but they don't intend to marry.
Her worry is a practical one. If he dies first, what happens to her financially?
In New Jersey, the answer can come as a shock. The state taxes a live-in partner much like a friend or a distant relative. That can mean a 15% to 16% tax on what she inherits, starting with the first dollar.
Here's how the tax works, what an NJ domestic partnership can and can't do, and what other options unmarried couples have.
This is general information, not legal or tax advice. Inheritance tax results depend on the facts, the type of asset, and how it is titled. Speak with a New Jersey estate planning attorney and a tax professional before acting.
Do Unmarried Partners Pay Inheritance Tax in New Jersey?
Yes. An unregistered partner is a Class D beneficiary under New Jersey law and pays 15% on the first $700,000 inherited and 16% above that. Living together for six, ten, or thirty years does not change the classification.
New Jersey repealed its estate tax for deaths on or after January 1, 2018, but it kept its inheritance tax. The two work differently. An estate tax depends on the size of the whole estate. The inheritance tax depends on who receives each asset and how much each person receives. Our guide on whether you have to pay New Jersey inheritance tax covers the basics for every type of heir.
The NJ Division of Taxation sorts beneficiaries into classes:
| Class | Who is included (examples) | NJ inheritance tax |
|---|---|---|
| Class A | Spouse, civil union partner, registered domestic partner (after July 10, 2004), children, grandchildren, parents, grandparents, stepchildren | Exempt |
| Class C | Siblings, half-siblings, a child's spouse or civil union partner | First $25,000 exempt, then 11% to 16% |
| Class D | Everyone else, including nieces, nephews, friends, and live-in partners who are not certified domestic partners | 15% on the first $700,000; 16% above $700,000 |
| Class E | Qualified charities and certain government entities | Exempt |

The state's own return instructions list live-in partners who are not certified domestic partners as a common example of a Class D beneficiary. The label is that direct.

There Is No Real Class D Exemption
A Class D beneficiary who receives less than $500 owes nothing. Once a Class D beneficiary receives $500 or more, though, the whole amount is taxable. The Division of Taxation states plainly that this is not a $499 exemption.
What the Tax Looks Like in Dollars
| Amount the unmarried partner inherits | Estimated NJ inheritance tax (Class D) | As a registered domestic partner |
|---|---|---|
| $100,000 | $15,000 | $0 |
| $300,000 | $45,000 | $0 |
| $500,000 | $75,000 | $0 |
| $1,000,000 | $153,000 ($105,000 on the first $700,000 + $48,000 on the next $300,000) | $0 |
[Review for accuracy: time-sensitive claim]
These are simplified examples. The real figure depends on what is reportable, any proven contributions by the survivor, deductions, and which assets are exempt no matter who receives them.
Deadlines, Interest, and Frozen Accounts
The tax is generally due within eight months of death. Unpaid tax after that date accrues interest at 10% a year. [Review for accuracy: time-sensitive claim]
The tax is also a lien on the decedent's New Jersey property for up to 15 years unless it is paid or bonded. Banks and brokerages generally need a state tax waiver before they release the decedent's New Jersey assets. A surviving partner may face delays getting access to money while the paperwork is sorted out.
What Is a Domestic Partnership in NJ?
An NJ domestic partnership is a legal relationship registered with the state. New registrations are open only to couples who are both 62 or older. A registered domestic partner is a Class A beneficiary, so the surviving partner owes no New Jersey inheritance tax.
The exemption is broad. Under the Domestic Partnership Act, all transfers to a surviving domestic partner by will, survivorship, or contract are exempt. That includes the value of any pension, annuity, retirement allowance, or co-op housing shares.
The catch is age. The Domestic Partnership Act took effect July 10, 2004. The Civil Union Act amended it on February 19, 2007. Since then, new domestic partnerships are available only to couples, same-sex or opposite-sex, who are both 62 or older. Partnerships registered before February 19, 2007 remain valid.
Who Qualifies
To register, both partners must:
- Be 62 or older
- Share a common residence
- Be jointly responsible for each other's common welfare, shown by joint financial arrangements or jointly owned property
- Agree to be jointly responsible for each other's basic living expenses during the partnership
- Not be married, in a civil union, or in another domestic partnership
- Not be related by blood or affinity up to and including the fourth degree of consanguinity
- Generally not have ended another domestic partnership within the past 180 days (this does not apply if the earlier partnership ended because a partner died)
To prove joint financial responsibility, the state accepts at least one of these: a joint deed, mortgage, or lease; a joint bank account; naming one partner as primary beneficiary in the other's will; naming one partner as primary beneficiary of the other's life insurance or retirement plan; or joint ownership of a motor vehicle.
How Do You File for a Domestic Partnership in NJ?
Both partners complete an Affidavit of Domestic Partnership and sign it together in front of a notary. Then they appear together to file it with a Local Registrar of Vital Statistics and pay a $28 fee. [Review for accuracy: time-sensitive claim]
The partnership is not registered until the affidavit is filed with the registrar. The NJ Department of Health domestic partnership FAQs list the full requirements.
Timing matters. For inheritance tax, the Division of Taxation looks at legal status as of the date of death. A surviving partner who claims the exemption needs a certified copy of the Certificate of Domestic Partnership. A couple who qualifies but waits until a health crisis may run out of time.
Domestic Partnership vs. Staying Unregistered: What Changes?
Registering removes New Jersey inheritance tax for the surviving partner and adds rights an unregistered partner does not have, including a spouse's share when there is no will. It does not make the couple married, and federal law still treats the partners as unrelated.
| Issue | Unregistered partner | Registered NJ domestic partner |
|---|---|---|
| NJ inheritance tax | Class D: 15% to 16% | Class A: exempt |
| Inheritance with no will | Nothing | Same intestate share as a surviving spouse |
| Medical or legal decisions for an incapacitated partner | Not automatic | Yes, under New Jersey's domestic partner notice |
| Hospital visitation | Not automatic | Yes |
| Treated as a spouse under federal law | No | No |
| Tenancy by the entirety for a shared home | No | No (spouses and civil union partners only) |
New Jersey's official notice to domestic partners also lists protection under the Law Against Discrimination, including in employment, housing, and credit. Registered partners also get an additional personal income tax exemption on the same basis as a spouse.
The intestacy point matters most for couples without wills. Under New Jersey's intestacy statute, as amended in 2023, a surviving domestic partner receives the same share as a surviving spouse. An unregistered partner receives nothing, and the estate goes to blood relatives. Our article on what happens when you die without a will explains how intestacy works.
Social Security survivor benefits are a possibility, not a promise. In a New Jersey case, the Social Security Administration's legal guidance concluded that a valid domestic partner could qualify for widow(er)'s benefits. Other requirements still apply, and SSA decides each case on its own facts, so couples should confirm with SSA.
On debts, a domestic partner is generally not liable for debts the other partner took on before the partnership, or took on in their own name during it.
What a Domestic Partnership Does Not Do
- It is not marriage. Domestic partners do not have all the property rights, workplace protections, and family-law protections of married couples.
- No federal estate tax deduction. Property passing to a domestic partner gets no federal marital deduction. For most couples this is academic, because the federal exemption is $15 million per person for 2026. [Review for accuracy: time-sensitive claim]
- No spousal rollover for retirement accounts. Most non-spouse beneficiaries must empty an inherited account within 10 years. An exception applies to an "eligible designated beneficiary," which includes someone not more than 10 years younger than the account owner. Our guide on what to do with an inherited IRA covers the options. This federal income tax is separate from New Jersey inheritance tax.
- No tenancy by the entirety. New Jersey's exemption for property held this way applies to spouses and civil union partners. The state's instructions do not extend it to domestic partners.
- Ending it requires court action. A domestic partnership ends through the New Jersey Superior Court, with filing fees equal to those for a divorce.
Can You Get a Domestic Partnership in NJ If You're Under 62?
No. If either partner is under 62, a new New Jersey domestic partnership is not available. That's where many couples get stuck. The good news is that several other tools can protect a surviving partner, and some can be combined.
1. Marriage or a Civil Union
Spouses and civil union partners are Class A beneficiaries, so they owe no New Jersey inheritance tax. To enter a civil union, each person must be at least 18 and not already in another civil union, domestic partnership, or marriage.
Marriage and civil unions bring legal obligations well beyond taxes, including those that apply if the relationship ends. For many couples, this is a personal decision as much as a financial one.
2. Life Insurance With a Named Beneficiary
This may be the most useful tool for an unmarried couple. Life insurance paid to a named beneficiary is exempt from New Jersey inheritance tax, whatever the beneficiary's class. Proceeds payable to the estate are taxable.
The policy should name the partner directly, not "my estate." For more on how proceeds are treated, see our article on whether life insurance is taxable to the beneficiary.
3. Certain Public Pensions
Death benefits from New Jersey's major public retirement systems are exempt. These include the Teachers' Pension and Annuity Fund (TPAF), the Public Employees' Retirement System (PERS), and the Police and Firemen's Retirement System (PFRS). Some federal survivor benefits paid to a named beneficiary are exempt too.
Not every plan qualifies. The state's supplemental annuity plan, the NJ Deferred Compensation Plan, and TIAA-CREF plans are not exempt.
4. Careful Beneficiary Designations on IRAs and 401(k)s
Naming a partner as beneficiary keeps an IRA or 401(k) out of probate. It does not by itself avoid New Jersey inheritance tax. Plans, annuities, and contracts payable to a named beneficiary must be reported, and the beneficiary's class sets the tax. Life insurance and the exempt public pensions above are the main exceptions.
5. Records for Joint Accounts and Joint Property
Many couples assume a joint account or a jointly owned house passes tax-free. In New Jersey, jointly held assets are presumed to have belonged entirely to the person who died.
A surviving owner who contributed must prove it with an affidavit and records, such as canceled checks or written agreements. Only then is the tax limited to the decedent's share. Keep records of who paid for what, including the down payment, mortgage payments, and deposits.
6. Lifetime Gifts and the Three-Year Rule
Giving assets away during life can reduce what passes at death. But New Jersey presumes that transfers made within three years of death were made "in contemplation of death" and are taxable. Transfers where the giver keeps the use or income of the property are taxable no matter when they were made.
Gifts made well in advance, and as part of a normal pattern, are treated more favorably. The Division still looks at the facts. For federal purposes, the 2026 annual gift exclusion is $19,000 per recipient. [Review for accuracy: time-sensitive claim] Our article on gifting money near the end of life goes deeper.
7. A Will and the Core Documents
Even when tax can't be avoided, a partner who isn't named in a will or on beneficiary forms may receive nothing. Every unmarried couple should consider:
- Wills naming each other
- A durable power of attorney for finances
- An advance directive and health care proxy, since an unregistered partner does not automatically get medical decision rights
- Updated beneficiary designations on every policy and account
The Law Firm of Benjamin D. Eckman's estate planning team prepares these documents for couples from offices in Union, Wayne, and Hackensack. If you're unsure how a power of attorney differs from guardianship, our guide on guardianship and power of attorney explains it.
8. Put Any Support Promises in Writing
New Jersey requires a "palimony" agreement to be in writing to be enforceable. This is a promise by one partner in a non-marital relationship to support the other.
In Moynihan v. Lynch (2022), the New Jersey Supreme Court struck down a separate requirement that both parties have independent legal advice. The agreement must still be written and signed, at least by the party it will be enforced against. A spoken promise to "always take care of you" will likely not hold up.
What Should Our Couple Do?
For the woman who has spent six years with her partner, the answer depends mainly on their ages.
If both are 62 or older, registering as domestic partners may be the simplest way to remove New Jersey inheritance tax on what she receives. It also adds intestacy rights, medical decision rights, and possibly Social Security survivor eligibility. They should register now, while both are healthy, and update wills and beneficiary forms at the same time.
If either is under 62, domestic partnership is not an option today. Their choices are marriage or a civil union, or a mix of named-beneficiary life insurance, careful titling and record-keeping, wills, powers of attorney, and a written agreement. Life insurance can be especially useful because it can give her tax-free funds to pay inheritance tax due on other assets.
Either way, doing nothing is the most expensive choice. An unregistered partner with no will can be left with nothing. One who is named in a will can still lose 15% to 16% of what she receives to the state.

Frequently Asked Questions
What is a domestic partnership in NJ?
A New Jersey domestic partnership is a legal relationship that two people register with a Local Registrar of Vital Statistics. Since February 19, 2007, new partnerships are open only to same-sex or opposite-sex couples who are both 62 or older. Registered partners are Class A beneficiaries, so the survivor owes no New Jersey inheritance tax. They also get hospital visitation rights, the right to make medical or legal decisions for an incapacitated partner, and a spouse's share of the estate if there is no will. Partnerships registered before February 19, 2007 remain valid.
Can you get a domestic partnership in NJ if you are under 62?
No. If either partner is under 62, a new New Jersey domestic partnership is not available. Couples in that situation can marry or enter a civil union, which also makes the survivor a Class A beneficiary. Other tools include life insurance that names the partner directly, exempt public pensions such as TPAF, PERS, and PFRS, careful records for joint property, and lifetime gifts made well before death. Every couple should also have wills, durable powers of attorney, and health care proxies naming each other.
How do you file for a domestic partnership in NJ?
Both partners complete an Affidavit of Domestic Partnership and sign it together in front of a notary. Then they appear together at a Local Registrar of Vital Statistics to file it and pay a $28 fee. The partnership is not registered until the affidavit is filed. Couples must also show proof of joint financial responsibility, such as a joint deed, lease, or bank account, or naming each other as primary beneficiary in a will, life insurance policy, or retirement plan.
Do unmarried partners pay inheritance tax in New Jersey?
Yes, unless they are registered domestic partners or civil union partners. New Jersey treats an unregistered live-in partner as a Class D beneficiary. Class D pays 15% on the first $700,000 inherited and 16% above that. Once a Class D beneficiary receives $500 or more, the whole amount is taxable, so there is no real exemption. On a $300,000 inheritance, that comes to about $45,000 in tax. A registered domestic partner would owe nothing on the same amount.
Is life insurance subject to NJ inheritance tax?
Life insurance paid to a named beneficiary is exempt from New Jersey inheritance tax, no matter which class the beneficiary falls into. That makes it one of the most useful tools for unmarried couples. The exemption does not apply when the proceeds are payable to the estate. To keep the exemption, the policy should name the partner directly rather than "my estate." Life insurance can also give a surviving partner tax-free cash to pay any inheritance tax due on other assets.
What is a civil union partner in NJ?
A civil union partner is a person in a civil union recognized under New Jersey law. For inheritance tax purposes, a civil union partner is a Class A beneficiary, the same as a spouse, so the survivor owes no New Jersey inheritance tax. Unlike a new domestic partnership, a civil union has no age-62 requirement. Each person must be at least 18 and not already in another civil union, domestic partnership, or marriage. A civil union brings legal obligations beyond taxes, including those that apply if it ends.
Does a domestic partner inherit if there is no will in New Jersey?
Yes. Under New Jersey's intestacy statute, as amended in 2023, a surviving registered domestic partner receives the same share as a surviving spouse when there is no will. An unregistered partner receives nothing. Without a will or beneficiary designations, the estate passes to blood relatives instead. That is why unmarried couples who are not registered should make wills naming each other and keep beneficiary forms up to date on every policy and account.
Does joint ownership protect an unmarried partner from NJ inheritance tax?
Not on its own. New Jersey presumes that jointly held assets belonged entirely to the person who died. A surviving owner who contributed must prove it with an affidavit and records, such as canceled checks or written agreements. Only then is the tax limited to the decedent's share. Unmarried couples should keep records of who paid for what, including the down payment, mortgage payments, and deposits. Tenancy by the entirety, which helps spouses and civil union partners, does not extend to domestic partners.
Protect Your Partner Before It's Too Late
New Jersey's inheritance tax hits unmarried partners hard, but you have options. Couples who are both 62 or older can register a domestic partnership and remove the tax entirely. Younger couples can combine life insurance, careful titling, wills, and powers of attorney to protect each other. The one thing that never helps is waiting.
The Law Firm of Benjamin D. Eckman has guided New Jersey families through estate planning and elder law for more than 25 years. We can review your situation, explain which options fit your ages and assets, and prepare the documents that put your plan in place.
