Do expats from New Jersey still need to pay state taxes?

Understanding New Jersey's tax obligations is important for expatriates with financial ties to the state. The tax laws in New Jersey are complex, and they hinge significantly on your residency status. Whether you're a resident, a nonresident, or a part-year resident affects your tax responsibilities deeply. 

For expats, this means navigating a landscape filled with intricate rules that dictate how your global income is taxed. In this introduction, we'll delve into why it's important for expats to grasp these complexities, helping ensure that they meet their legal requirements without facing unexpected tax burdens. 


Yes, expats from New Jersey who are domiciled in the state are still required to pay New Jersey state taxes on their worldwide income. 

New Jersey tax law requires that you file a state tax return if you are domiciled in the state, regardless of whether you are a resident or not. 

This means that even if you no longer live in New Jersey but maintain your domicile there, you are still required to file and pay taxes on your worldwide income.

Understanding residency status in New Jersey


A resident of New Jersey is someone who either maintains a permanent home in the state or spends more than 183 days there during the tax year. If New Jersey is your domicile, you are required to pay state taxes on all your income, no matter where it is earned. This includes global income, which is taxed by New Jersey if it remains your primary home base.


Nonresidents are individuals who do not maintain a permanent home in New Jersey and spend fewer than 183 days in the state during the tax year. They are only taxed on income that is sourced to New Jersey.

This includes earnings from work performed within the state, income from businesses located in New Jersey, or income from property situated in New Jersey. Nonresidents must use specific forms to declare and pay taxes on their New Jersey-sourced income.

New Jersey-Sourced Income

Income considered as sourced from New Jersey includes, but is not limited to:

  • Wages and salaries: Money earned from employment performed in New Jersey.
  • Business income: Income from business activities conducted in New Jersey, regardless of the business' location.
  • Rental income: Income derived from property located within New Jersey.
  • Capital gains: Profits from the sale of real estate or tangible personal property located in New Jersey.

Part-Year Resident

Part-year residents are those who either move to or from New Jersey during the tax year. This status requires individuals to file taxes as residents for the portion of the year they lived in New Jersey and as nonresidents for the remainder of the year. This allows them to appropriately allocate their taxable income based on where it was earned throughout the year.


Expatriates from New Jersey who still consider the state their domicile are required to pay state taxes on their worldwide income.

New Jersey law mandates that if the state remains your domicile—essentially your permanent home or the place to which you intend to return—you must file a state tax return, regardless of your current country of residence.

This ensures that all global income is appropriately reported and taxed under New Jersey law.

Why should New Jersey expats move domicile to a state with zero state income tax?

State income tax savings

For retirees and high-income individuals from New Jersey, moving to states without income taxes such as Florida, Texas, or Nevada can offer significant financial advantages. Without the burden of state income taxes, you can keep more of your earnings, allowing for greater investment opportunities or an enhanced lifestyle.

Inheritance tax benefits

States like Florida and Texas not only lack a state income tax but also do not impose state estate taxes. This can considerably reduce the tax burden on your estate, ensuring that more wealth is passed on to your heirs. This is especially advantageous for individuals with substantial assets who wish to maximize the inheritance for their beneficiaries.

Flexibility and mobility

Relocating your domicile to a no-income-tax state enhances your flexibility and mobility, allowing you to travel and live in various locations without worrying about high state tax bills. This is ideal for high-income earners with business interests in multiple states or countries and for retirees who desire to spend their later years exploring new places.

Moreover, the absence of state income taxes simplifies your tax filing process. You will only need to file federal taxes, reducing the complexity and potential for errors in your tax returns and making financial management more straightforward.

Tax benefits and exemptions for New Jersey expats

Living abroad as an expat comes with various federal tax benefits and exemptions that can help reduce your overall tax burden. Here are some of the key federal tax advantages available:

Foreign Earned Income Exclusion (FEIE)

The FEIE allows U.S. taxpayers living abroad to exclude a certain amount of their foreign-earned income from U.S. federal income tax.

For the tax year 2024, this exclusion amount is up to $126,500.

To qualify, you must pass either:

  • Bona Fide Residency Test: You qualify if you are a resident of a foreign country for an uninterrupted period that includes an entire tax year.
  • Physical Presence Test: You qualify if you are physically present in a foreign country for at least 330 full days during a 12-month period.

FEIE Guide

Foreign Tax Credit (FTC)

The FTC helps you avoid double taxation by allowing you to take credit for foreign taxes paid on income that is also subject to U.S. federal tax.

This credit can significantly reduce your U.S. tax liability, especially if you reside in a country with high tax rates.

FTC Guide

Foreign Housing Exclusion (FHE)

The FHE allows you to exclude certain housing expenses from your federal taxable income, including rent, utilities (excluding telephone), and other reasonable expenses related to housing abroad. The amount you can exclude is limited to a base amount plus housing expenses exceeding 16% of the FEIE limit.

Filing requirements for New Jersey expats

Filing state taxes from abroad can be straightforward once New Jersey expatriates understand the necessary steps and forms.

How to file New Jersey state taxes from abroad:

1. Gather your documents 

Before you begin the filing process, collect all pertinent financial documents. This includes worldwide income statements, proof of income from New Jersey sources, and any records of the days spent in New Jersey during the tax year.

2. Choose the correct form:

  • NJ-1040: This is the form used by residents. As an expat, if you are considered a resident of New Jersey for tax purposes, you would use this form to report your global income.
  • NJ-1040NR: Nonresidents should use this form, which is designed to report income earned from New Jersey sources only.
  • For part-year residents, the NJ-1040 form is used, and income must be allocated to the periods of residency and non-residency as applicable.

3. File electronically

New Jersey encourages taxpayers to file electronically for faster processing and quicker refunds. The state supports several e-filing services that expatriates can access from anywhere in the world.

4. Manual filing

If electronic filing is not an option, expatriates can also mail their tax returns to the New Jersey Division of Taxation. Be sure to use the correct mailing address, which varies depending on whether a payment is included with the return.

Penalties for non-compliance

Failing to meet tax obligations in New Jersey can lead to significant consequences, including various penalties and fines. Understanding these penalties can help ensure compliance and avoid unnecessary financial burdens.

Late filing and payment penalties

  • Late filing: If you file your tax return after the due date and do not have an extension, New Jersey imposes a late filing penalty. The penalty is typically 5% of the tax due for each month or part of a month the return is late, up to a maximum of 25%.
  • Late payment: If you pay your taxes late, the penalty is 0.5% per month on the balance due, up to a maximum of 25%. This penalty starts accruing the day after the tax is due until it is paid.

Underpayment of estimated tax penalty

If you do not pay enough through withholding or estimated tax payments, you may be subject to an underpayment penalty. This penalty applies if you owe more than a certain amount when you file your return. The penalty calculation is complex and depends on the amount underpaid and the period of underpayment.

If your return shows an understatement of tax due to negligence or disregard of rules and regulations, New Jersey may assess an accuracy-related penalty. This can be significant, typically 10% of the underpayment attributable to the negligence.

Fraud penalties

In cases of tax fraud or intentional disregard of New Jersey tax laws, more severe penalties can be imposed. These penalties are much higher and may also lead to criminal charges.

Collection costs

If the state needs to take action to collect overdue taxes, such as through a levy or lien, the taxpayer can be charged additional fees and costs associated with the collection process.
