New Jersey taxes you on income earned while you lived there, even after you move

New Jersey does not have a formal "exit tax" — a one-time fee charged when you leave the state. Instead, New Jersey taxes you on income you earned during the years you were a resident, and that obligation continues even after you move away. If you worked in New Jersey or received income from New Jersey sources while living there, you owe New Jersey income tax on that money for those years, regardless of where you live now.

The key distinction is timing. You pay tax on income earned during the tax year you earned it, not on the year you leave. If you moved to Pennsylvania in June 2024, you would owe New Jersey income tax on what you earned from January through June 2024. You would not owe New Jersey tax on income earned after you moved, unless that income came from a New Jersey source — such as rental property, a business, or investment income tied to the state.

New Jersey also taxes nonresidents on income earned within the state. If you moved out of state but still work remotely for a New Jersey employer, or own rental property in New Jersey, you may owe New Jersey tax on that income even though you no longer live there.

Key Takeaways

  • New Jersey taxes income earned while you were a resident, and that tax obligation does not end when you move to another state.
  • You owe tax only on income earned during the years you lived in New Jersey, not on income earned after you moved away.
  • If you move out of state but continue to earn income from New Jersey sources — such as rental property or a remote job for a New Jersey employer — you may still owe New Jersey income tax on that income.
  • You must file a part-year resident return for the year you moved, reporting income earned only during the months you lived in New Jersey.

How the part-year resident return works

When you move out of New Jersey during a tax year, you file a part-year resident return instead of a full-year return. This return reports only the income you earned from January 1 through the date you moved. New Jersey's Division of Taxation uses your move date to calculate which months count as resident income.

You will need documentation of your move date — typically a lease or deed showing when you took occupancy in your new state, or a utility bill with a start date. New Jersey may ask for this proof if you file a part-year return. The state wants to verify that you actually moved and did not straightforward claim a move date to reduce your tax bill.

If you moved partway through the year, you may also owe tax to your new state on income earned after you moved. Most states tax residents on all income earned while they lived there, so you could owe tax to both states on the same income if you moved mid-year. However, many states offer credits for taxes paid to other states, so you may not pay double tax on the same dollar.

Nonresident tax on New Jersey income sources

Even after you move out of state, New Jersey taxes you on income that comes from within the state. This includes rental income from property you own in New Jersey, business income from a New Jersey business you still operate, and income from investments or partnerships based in New Jersey.

If you work remotely for a New Jersey employer after moving out of state, the tax treatment depends on where the work is performed. If you work from your home in another state, New Jersey generally does not tax that income — your new state does. However, if you travel back to New Jersey to work in the office, or if your employer considers you a New Jersey employee, New Jersey may claim tax on your wages. This is a gray area, and the answer depends on your specific situation and how your employer reports your income.

The safest approach is to contact New Jersey's Division of Taxation before you move if you have questions about whether your income will still be taxed by the state. You can reach them through the New Jersey Department of the Treasury website.

Filing important date and penalties for moved residents

Your New Jersey income tax return is due on the same date as your federal return — typically April 15. This important date does not change because you moved. If you file late or do not file at all, New Jersey charges penalties and interest on any tax owed.

The penalty for not filing is usually 5 percent of the unpaid tax for each month the return is late, up to 25 percent total. Interest accrues daily on unpaid tax at a rate set by the state each quarter. If New Jersey discovers you owe tax and did not file, the penalties and interest can add significantly to what you owe.

If you moved and did not know you still owed New Jersey tax, contact the Division of Taxation as soon as you realize the issue. The state sometimes reduces penalties for taxpayers who file late but have a reasonable explanation, though this is not may provide.

Reciprocal tax agreements and credits

New Jersey has reciprocal tax agreements with Pennsylvania and some other states. These agreements allow residents of one state who work in the other to be taxed by their home state rather than the state where they work. However, these agreements explore only to wages earned while you were working in the other state — not to income earned while you lived in New Jersey.

If you moved to a state that has a reciprocal agreement with New Jersey, that agreement does not erase your obligation to pay tax on income you earned while living in New Jersey. It only affects how you are taxed on income earned after you moved.

Your new state may offer a credit for taxes paid to New Jersey, which reduces the tax you owe to your new state by the amount you paid to New Jersey. This prevents double taxation on the same income, though the credit is limited to the tax your new state would have charged on that income.

What happens if you do not file or pay

If you move out of state and do not file a New Jersey return or pay tax owed, New Jersey can pursue collection through several methods. The state can place a lien on property you own in New Jersey, intercept your federal tax refund, or report the debt to credit agencies. If the amount owed is large enough, New Jersey may pursue legal action.

New Jersey also shares information with other states through the Multistate Tax Commission. If you owe New Jersey tax and move to another state, that state may be notified of the debt. This can affect your ability to renew a driver's license or register a vehicle in your new state, depending on that state's policies.

The longer you wait to address an unpaid New Jersey tax bill, the more penalties and interest accumulate. If you owe money, filing a return and working out a payment plan is usually less expensive than ignoring the debt and facing collection action.

Frequently Asked Questions

Do I owe New Jersey tax if I moved out of state in the middle of the year?

Yes, but only on income you earned while you lived in New Jersey. You file a part-year resident return reporting income earned from January 1 through your move date. Income earned after you moved is taxed by your new state, not New Jersey.

What if I own rental property in New Jersey but live in another state?

You owe New Jersey tax on the rental income from that property. New Jersey taxes nonresidents on income earned from sources within the state, which includes rental property. You file as a nonresident and report only the rental income on your New Jersey return.

Can I get a credit for taxes paid to New Jersey when I file in my new state?

Many states offer a credit for taxes paid to other states, but the amount and rules vary. Check with your new state's tax authority to see whether it allows a credit for New Jersey taxes paid. The credit usually cannot exceed the tax your new state would have charged on that income.

What documents do I need to prove I moved out of state?

New Jersey typically accepts a lease, deed, or utility bill showing your move date and new address. Keep copies of any documents that show when you established residency in your new state. If you file a part-year return, have these documents ready in case the state asks for proof.

What if I did not file a New Jersey return after I moved?

Contact New Jersey's Division of Taxation and file the return as soon as possible. The state charges penalties and interest on unpaid tax, but filing late is better than not filing at all. The Division of Taxation can tell you what you owe and discuss payment options.
