In New Jersey, the tax rate on inheritance varies based on the relationship between the beneficiary and the deceased. While some heirs are exempt from paying inheritance tax, others may owe up to 16%. Understanding these tax rates can help beneficiaries plan accordingly and avoid unexpected financial burdens.

Inheritance Tax Rates in New Jersey

New Jersey classifies beneficiaries into different categories, each with its own tax treatment:

  • Class A Beneficiaries – Exempt from inheritance tax. This group includes:
    • Spouses
    • Domestic partners
    • Parents
    • Grandparents
    • Children (including stepchildren and adopted children)
  • Class B Beneficiaries – This classification no longer exists under NJ tax law.
  • Class C Beneficiaries – Subject to tax but at a reduced rate. This group includes:
    • Siblings
    • Sons-in-law and daughters-in-law
    • Surviving spouses of deceased children

    • 15% on inheritances up to $700,000

Other Considerations

New Jersey does not impose an estate tax, but the federal estate tax may apply to estates exceeding $13.61 million (as of 2024). Additionally, life insurance proceeds payable to a named beneficiary are not subject to inheritance tax in NJ.

Planning for Inheritance Tax

To reduce tax liabilities, estate planning strategies such as gifting assets during one’s lifetime, setting up trusts, or designating tax-exempt beneficiaries can be useful. Consulting with a tax professional can ensure that the inheritance process is as tax-efficient as possible.


Introduction

Understanding New Jersey’s inheritance tax is crucial for beneficiaries, executors, and estate planners. Unlike estate tax, which is levied on the estate before distribution, inheritance tax is imposed on the beneficiaries receiving assets. Navigating these tax laws can be complex, making the expertise of a New Jersey inheritance tax accountant invaluable. This guide explores tax rates, exemptions, filing requirements, and strategies to minimize inheritance tax liabilities.

How Much Tax Do You Pay on Inheritance in NJ?

New Jersey’s inheritance tax rates vary depending on the beneficiary’s relationship to the deceased:

  • Class A Beneficiaries (spouses, parents, children, grandchildren) – Exempt from inheritance tax. These individuals do not have to file an inheritance tax return, and they receive their inheritance tax-free.
  • Class C Beneficiaries (siblings, sons/daughters-in-law) – Taxed at 11%-16% based on the inheritance amount. The first $25,000 is exempt, with rates applied progressively: 11% on amounts between $25,000 and $1.1 million, 13% on amounts up to $1.4 million, 14% on amounts up to $1.7 million, 15% up to $2 million, and 16% on anything above that.
  • Class D Beneficiaries (friends, distant relatives, non-family members) – Taxed at 15%-16%, with no exemption. The tax rate is 15% on the first $700,000 and 16% on any amount exceeding that.

Example Tax Calculation:

  • A sibling inheriting $50,000 pays 11% on the amount over $25,000. That means $2,750 in inheritance tax ($25,000 x 11%).
  • A friend inheriting $100,000 pays 15% on the full amount, resulting in $15,000 in inheritance tax.
  • A distant relative inheriting $800,000 pays 15% on the first $700,000 ($105,000) and 16% on the remaining $100,000 ($16,000), totaling $121,000 in inheritance tax.

How to Avoid Inheritance Tax in NJ

There are several legal strategies to reduce or avoid inheritance tax:

  • Gifting Assets Before Death: Transferring assets while still alive can significantly reduce taxable inheritance. However, large gifts may be subject to federal gift tax regulations, so proper planning is necessary.
  • Creating Trusts: Establishing irrevocable trusts allows assets to be passed on in a tax-efficient manner. Certain types of trusts, such as grantor retained annuity trusts (GRATs) and life insurance trusts, can help reduce or eliminate inheritance tax burdens.
  • Favoring Tax-Exempt Beneficiaries: Since Class A beneficiaries (spouses, children, and parents) are exempt from inheritance tax, structuring an estate to favor them can minimize taxes. This can include transferring assets to children instead of siblings or more distant relatives.
  • Charitable Donations: Leaving a portion of an estate to qualified charities can lower the overall taxable estate value and potentially eliminate inheritance tax for other beneficiaries.
  • Joint Ownership and Beneficiary Designations: Naming Class A beneficiaries on life insurance policies, retirement accounts, or jointly held property ensures these assets pass directly to them, bypassing inheritance tax.

An inheritance tax accountant can help implement these strategies effectively, ensuring compliance with state and federal tax laws while optimizing estate planning for beneficiaries.

Did NJ Do Away With Inheritance Tax?

No, New Jersey eliminated its estate tax in 2018, but inheritance tax still applies. It is important to understand the key distinction between these two types of taxes:

  • Estate Tax: This tax was previously imposed on the total value of an estate before distribution to heirs. New Jersey officially repealed its estate tax as of January 1, 2018, meaning estates are no longer subject to state estate tax.
  • Inheritance Tax: Unlike estate tax, inheritance tax is levied on certain beneficiaries after they receive their inheritance. The amount owed depends on the beneficiary’s relationship to the deceased and the value of the inheritance.

Despite the elimination of the estate tax, the inheritance tax can still pose significant financial burdens for certain heirs, especially Class C and Class D beneficiaries. Proper tax planning can help reduce these obligations and maximize the wealth passed on to loved ones.

Who Must File a New Jersey Inheritance Tax Return?

Typically, the executor or estate administrator must file an inheritance tax return if applicable. Key details:

  • Deadline: The return must be filed within eight months of the decedent’s death. Failure to file on time may result in penalties and interest charges.
  • Required Forms:
    • Form IT-R (Resident decedent’s estate) – Used when the deceased was a New Jersey resident.
    • Form IT-NR (Non-resident decedent with NJ assets) – Required if a non-resident owned assets in New Jersey.

Additionally, beneficiaries receiving property subject to inheritance tax should be aware of potential tax assessments and ensure proper documentation is maintained.

Will I Pay Taxes on Money I Inherit?

  • New Jersey: Inheritance tax applies based on the beneficiary’s classification.
  • Federal Taxes: Inherited money itself is not considered taxable income at the federal level. However, any earnings generated from inherited assets, such as interest, dividends, or capital gains, may be subject to federal income tax. If you inherit a retirement account such as an IRA or 401(k), you may have to pay taxes on withdrawals depending on the type of account and distribution rules.

Why Work with a New Jersey Inheritance Tax Accountant?

An inheritance tax accountant provides:

  • Expert Tax Guidance: Ensuring compliance with NJ tax laws and regulations.
  • Tax Reduction Strategies: Helping beneficiaries and estate planners legally minimize inheritance tax liabilities through proactive planning.
  • Estate Tax Planning: Assisting executors and estate administrators in accurately preparing and filing required tax forms.

Selling a home in New Jersey comes with its own tax implications. Whether individuals are moving out of New Jersey or selling a home within the state, they might be subject to capital gains tax, the New Jersey Exit Tax as well as other state tax obligations. 

1. NJ Capital Gains Tax on Home Sales

Any profit from the sale may be subject to capital gains tax at both federal and NJ state levels. The amount is determined in line with the difference between the selling price and the original purchase price. Improvements and eligible expenses should be taken into consideration as well.

  • Federal Capital Gains Tax: Ranges from 0% to 20% depending on the income bracket.
  • New Jersey Capital Gains Tax: Taxed as ordinary income at state rates. It can go up to 10.75% for high earners.

Primary Residence Exclusion

If the home was the primary residence for at least two of the last five years, qualification for an exclusion is possible:

  • Up to $250,000 in gains for single filers
  • Up to $500,000 for married couples filing jointly

This means if the profit is below these mentioned amounts, you may not owe federal or NJ capital gains tax.

2. New Jersey Exit Tax Withholding

Many homeowners worry about the NJ Exit Tax in the case of selling their property. It sounds like a penalty at first. However, it is actually a withholding tax to make sure that non-residents complete their NJ tax obligations before moving out.

  • 8.97% of the taxable gain, OR
  • 2% of the total sale price (whichever is higher)

Even if the actual NJ capital gains tax is lower, this amount is withheld at closing. A refund can be filed if the withholding exceeds what you actually owe.

3. Withholding Tax on Real Estate Sales

For non-residents, NJ necessitates an upfront withholding amount in order to cover potential taxes. However, full-time residents selling a home in New Jersey do not have to pay such withholding tax if they remain in the state.

Reducing or Avoiding NJ Exit Tax Withholding

  • An NJ driver’s license, tax returns or voter registration can be provided at the time of sale.
  • If the profit is minimal or zero, you may not owe the withholding tax.
  • If too much is withheld, a Form NJ-1040NR can be submitted to claim a refund.

Final Thoughts

The amount of tax to be paid in the case of selling a house in NJ depends on whether the individual is a resident, the capital gains as well as the property’s sale price. A New Jersey tax professional can present assistance in the context of tax benefit maximization as well as preventing unnecessary withholding.


Selling a home in New Jersey can come with tax implications in terms of capital gains taxation. However, there are methods to lower or even eliminate such a tax burden in line with the specific situations. We present legal strategies in order to prevent unnecessary taxation liabilities regarding capital gains when selling a home in New Jersey.

1. The Primary Residence Exclusion

Qualifying for the primary residence exclusion in accordance with the IRS rules is possible in order to prevent capital gains taxation. This exclusion enables homeowners to exclude:

  • Up to $250,000 of capital gains if filing as a single taxpayer.
  • Up to $500,000 of capital gains if married and filing jointly.

The ownership and use test should be met to qualify:

  • The individual has owned and lived in the home as the primary residence for at least two of the last five years before the sale.
  • The exclusion applies only to a primary residence, not to rental or investment properties.

2. Minimal or No Gain

There are factors that reduce taxable gains as outlined below:

  • Purchase Price & Sale Costs: The capital gain is calculated by subtracting the original purchase price as well as eligible expenses from the sale price.
  • Home Improvements: Costs for significant home upgrades like kitchen renovations and roof replacements alongside room additions might be added to the original purchase price and lower the taxable gain.

3. 1031 Exchange (For Investment Properties)

A 1031 exchange can be leveraged to defer capital gains tax by reinvesting the proceeds into another qualifying property as detailed below:

  • The replacement property should be of equal or greater value than the sold property.
  • The transaction must adhere to IRS timelines including identifying a replacement property within 45 days and closing within 180 days.
  • Both properties should be investment or business properties (not primary residences).

4. Eligible Deductions

The following deductions can be considered to lower the taxable amount:

  • Real estate agent commissions
  • Legal and closing fees
  • Title insurance
  • Necessary repairs before the sale

5. Establishing NJ Residency Before Selling

If the individuals are residents at the time of the sale, they may avoid this withholding by establishing residency via:

  • A valid NJ driver’s license
  • Filing NJ state tax returns
  • Showing proof of address like utility bills or voter registration

6. A Refund if Over-Taxed

If the amount withheld at closing surpasses the actual tax liability, a New Jersey Nonresident Income Tax Return (Form NJ-1040NR) can be filed to claim a refund.

If individuals are selling a home in New Jersey and planning to leave the state, they might have come across the term New Jersey Exit Tax. It is actually a withholding tax on real estate sales to make sure that the state collects taxes owed before sellers relocate. We present how such tax is calculated as outlined below:

The NJ Exit Tax Calculation

The New Jersey Exit Tax applies to non-residents selling property in the state. Instead of waiting for sellers to file a tax return, the state necessitates a withholding at closing. The calculation follows the two methods below:

  • 8.97% of the taxable gain on the property sale, or
  • 2% of the total sale price, whichever is greater.

This methodology makes sure that New Jersey collects at least a portion of the capital gains tax from the sale even if the seller no longer files a New Jersey tax return.

Example NJ Exit Tax Calculation

The following scenarios can be taken into consideration in order to illustrate how the tax is determined:

Scenario 1: High Capital Gain

  • Home Purchase Price: $300,000
  • Sale Price: $500,000
  • Taxable Gain: $200,000
  • Exit Tax: 8.97% of $200,000 = $17,940

Scenario 2: Low Capital Gain but High Sale Price

  • Home Purchase Price: $480,000
  • Sale Price: $500,000
  • Taxable Gain: $20,000
  • 8.97% of $20,000 = $1,794 (lower than 2% of the sale price)
  • Exit Tax: 2% of $500,000 = $10,000 (higher amount applies)

Key Takeaways

  • If 8.97% of the taxable gain is greater than 2% of the sale price, the seller is taxed on the gain.
  • If 2% of the sale price is greater, the withholding is based on the total sale price.

Can You Get a Refund?

Yes! If the amount withheld exceeds the actual tax liability, a New Jersey Nonresident Income Tax Return (Form NJ-1040NR) can be filed after the sale to claim a refund.

Conclusion

The New Jersey Exit Tax is not an extra fee but a prepaid withholding tax. Such tax is established to make sure that real estate taxes are paid. Acknowledging the surrounding rules can aid in minimizing the impact. CPA experts can present professional assistance for exemption or refund possibilities.


The term New Jersey Exit Tax appears in the case of selling a home in New Jersey and moving out of the state. It might sound like a penalty fee for leaving the state. However, it is actually a withholding tax liability on real estate sales. Below, we present where such a tax came from and who introduced it.

The Origins of the NJ Exit Tax

The New Jersey Exit Tax was introduced in 2004 under then-Governor Jim McGreevey. However, it is not an extra tax—it is a withholding mechanism in order to make sure that non-residents pay their New Jersey real estate tax and NJ capital gains tax before leaving the state.

The purpose of this tax can be outlined as below:

  • Tax Compliance: Before 2004, non-residents who sold property in New Jersey and left the state were able to prevent paying the required taxation burden. This law establishes that sellers complete their taxation obligations upfront.
  • Withholding to Secure Payment: Instead of chasing former residents for unpaid taxes, the state necessitates a withholding of either 8.97% of the taxable gain or 2% of the sale price, whichever is greater.
  • Preventing Revenue Loss: With many people moving out of New Jersey, the state would like to avoid revenue gaps from unpaid real estate taxes.

Who Started the Exit Tax in NJ

The fundamental information is outlined below if you are selling a home in New Jersey:

Conclusion

Why Does New Jersey Have an Exit Tax?

The NJ exit tax is not an additional tax. Instead, it is a method for the state to collect taxes owed at the time of sale.

This approach targets that New Jersey collects at least a portion of the capital gains tax owed, even if the seller does not remain in the state. In the case the amount withheld exceeds the actual tax liability, the seller can file a New Jersey Nonresident Income Tax Return to claim a refund.

How the New Jersey Exit Tax is Calculated

The New Jersey Exit tax necessitates sellers to prepay state taxes before moving out of New Jersey in the case of home selling. The withholding is calculated in line with the higher of the below two amounts:

  • 8.97% of the taxable gain (capital gain) from the sale
  • 2% of the total sale price

Example Calculation

Suppose a property is sold for $500,000 with a $100,000 gain:

  • 8.97% of the gain: $8,970
  • 2% of the sale price: $10,000
