Reciprocity
Do New York and New Jersey Have a Tax Reciprocity Agreement?
No. New York does not have a reciprocity agreement with New Jersey or any other state. New Jersey also has no reciprocity with New York, though it does maintain an agreement with Pennsylvania. Without reciprocity, each state taxes the income it can claim: New Jersey taxes nonresidents on income earned within its borders, and New York taxes its residents on all income regardless of source.
A reciprocity agreement, where one exists, allows employees to pay income tax only to their home state. Without one, both states assert a taxing right over the same wages. A NY resident working in NJ cannot ask their NJ employer to withhold only New York tax. The employer must withhold New Jersey state income tax, and the NY resident must file returns in both states each year, using a credit mechanism on Form IT-112-R to avoid paying double tax on the same income. The result is dual filing with a credit that ensures you pay the higher of the two states' rates on that income, not both rates added together.
Filing Obligations
Which Tax Returns Do I File as a NY Resident Working in NJ?
| Obligation | State | Form |
|---|---|---|
| Resident return | New York | IT-201 |
| Nonresident return | New Jersey | NJ-1040NR |
| Credit for NJ taxes paid | Claimed on IT-201 | IT-112-R |
File the New Jersey nonresident return (NJ-1040NR) first. You need the final NJ tax figure to calculate the credit on your New York return. On the NJ-1040NR, report only income sourced to New Jersey, which generally means wages for services performed in the state. On the NY IT-201, report all income from every source, then claim the credit on Form IT-112-R for taxes paid to NJ.
If you are married filing jointly and only one spouse works in New Jersey, both spouses still report all combined income on the NY IT-201. The NJ-1040NR covers only the income of the spouse who earned NJ wages.
Both returns are due by April 15. Filing an extension with one state does not automatically extend the other. Submit Form IT-370 to New York and NJ-630 to New Jersey if you need more time.
Resident Credit
How Does the NY Resident Credit Prevent Double Taxation?
New York taxes its residents on all worldwide income. New Jersey taxes nonresidents on income earned within the state. Without a credit, you would pay both states' full tax on your NJ wages. New York's Form IT-112-R credit eliminates this overlap.
The credit equals the lesser of:
- The income tax you actually paid to New Jersey on your NJ-source income, or
- The New York tax attributable to that same income
If New Jersey's tax on your income is lower than what New York charges on the same amount, the credit covers the full NJ amount, and you owe the difference to New York. If NJ's tax is higher on certain income levels, the credit caps at the NY tax on that income, and your total state tax equals the NJ amount.
Either way, your total state tax on dual-taxed income equals the higher of the two states' rates, not the sum of both. The credit applies to wages and business income but generally excludes interest, dividends, and lottery winnings. Attach a copy of your completed NJ return when filing Form IT-112-R to support the credit claim.
Employer Withholding
How Should My NJ Employer Handle Withholding?
Your New Jersey employer withholds New Jersey state income tax from your wages. This is required for all employees performing services in New Jersey, regardless of where they live. The employer does not withhold New York state tax.
Because only NJ tax is withheld, you may owe New York a balance when you file. The IT-112-R credit offsets some of your NY liability, but if NY's effective rate exceeds NJ's rate on your income, you owe the difference. To avoid a large April bill:
- Make quarterly estimated payments to New York using Form IT-2105 if you expect to owe more than $300 in NY tax after credits and withholding.
- Estimated payments are due April 15, June 15, September 15, and January 15 of the following year.
- If you also have a job in New York, ask that employer to increase NY withholding to help cover the gap.
Review your withholding balance each year. Changes in income, filing status, or rate adjustments can shift how much you owe each state.
Remote Work
What Happens If I Work Remotely from New York for a NJ Employer?
New Jersey does not apply a convenience of the employer rule. NJ taxes nonresidents only on income for services physically performed in New Jersey. If you work from your NY home for your NJ employer, New Jersey does not tax those remote workdays.
From the New York side, this changes your credit calculation but not your total tax. Days worked from home in New York are not NJ-source income, so you pay no NJ tax on that portion. Since NY taxes you as a resident on all income regardless of where you earned it, fewer NJ-taxed days means a smaller IT-112-R credit and a larger balance due to New York. Your total state tax stays roughly the same, because the income simply shifts from NJ taxation to NY taxation.
Keep a log of days worked in each state. Both NJ and NY may ask for documentation supporting your income allocation. Badge scans, calendar entries, or employer records can serve as evidence if either state questions your day count.

| IT-112-R credit (lesser of NJ or NY tax) | $3,607 |
| NY balance due after credit | $1,225 |
| Total state income tax | $4,832 |

Mid-Year Move
What If I Moved Between New York and New Jersey During the Year?
If you changed your permanent residence during the year, file as a part-year resident in each state. In New York, Form IT-203 handles both part-year resident and nonresident situations. In New Jersey, use Form NJ-1040 for any period of NJ residency.
During the months you lived in New York, NY taxes you as a resident on all income from every source. During any months you lived in New Jersey, NJ taxes you as a resident on all income, and NY taxes you only on NY-source income. The credit mechanism still applies to the period where both states claim the same dollars.
Keep your exact move date documented. Both states require you to identify when your residency changed. Lease agreements, utility records, and driver's license changes serve as evidence. The date you establish or abandon domicile determines which periods are taxed as resident or nonresident in each state.
Withholding Errors
What If My Employer Withheld for the Wrong State?
If your NJ employer mistakenly withheld New York tax instead of New Jersey tax, you will owe New Jersey when you file the NJ-1040NR. Pay the balance due with the return. Claim the incorrectly withheld NY amount as a payment on your IT-201, and New York will refund the overpayment or apply it to your balance.
The correct setup is NJ withholding only from your NJ employer. File both returns as described above and claim the IT-112-R credit for NJ taxes paid. If you owe NY after applying the credit, pay it with your IT-201 filing or set up estimated payments going forward to avoid underpayment penalties. Contact your employer's payroll department to correct the withholding state code on future paychecks as soon as you notice the error.
Local Taxes
Do Local Income Taxes Apply in the NJ-NY Corridor?
New Jersey does not impose any local or municipal income tax. Your NJ obligation consists solely of the state's graduated income tax, with rates from 1.4% to 10.75% depending on filing status and taxable income.
New York City imposes its own income tax on residents of the five boroughs, with rates from 3.078% to 3.876%. If you live in NYC and commute to NJ, you owe NYC income tax on all your income, including wages earned in New Jersey. This applies on top of New York State tax. The IT-112-R credit reduces your New York State tax liability but does not offset the NYC income tax.
Yonkers imposes a resident surcharge and a separate nonresident earnings tax. If you live in Yonkers and work in NJ, you owe the Yonkers resident surcharge. The nonresident earnings tax (0.5%) applies only to people who work in Yonkers, not to Yonkers residents working elsewhere.
The NJ-NY corridor is simpler than some cross-border commutes for local taxes, because New Jersey has no local income tax. Compare this to the NJ-PA crossing where Pennsylvania's local earned income tax applies to nonresidents.
Questions
Work in New Jersey, Live in New York: How Taxes Work FAQ
Do New York and New Jersey have a tax reciprocity agreement?
No. Neither state has a reciprocity agreement with the other. New York does not maintain reciprocity with any neighboring state. New Jersey has reciprocity only with Pennsylvania. You must file a New Jersey nonresident return (NJ-1040NR) and a New York resident return (IT-201) each year. New York provides a credit on Form IT-112-R for income taxes paid to New Jersey, which prevents paying both states' full rates on the same wages.
Which state return should I file first?
File the New Jersey nonresident return (NJ-1040NR) first. You need the final NJ tax amount to calculate the resident credit on your New York IT-201. On Form IT-112-R, enter the NJ tax paid and the income taxed by NJ. The credit equals the lesser of the NJ tax paid or the NY tax attributable to that same income.
Does my NJ employer need to withhold New York tax?
No. New Jersey law requires employers to withhold NJ state income tax from wages earned in the state. The employer is not required to also withhold New York tax. You may need to make quarterly estimated payments to New York using Form IT-2105 if you expect to owe NY more than $300 after applying the IT-112-R credit for NJ taxes paid.
Do I owe NYC income tax if I live in the city but work in New Jersey?
Yes. NYC income tax applies to all city residents regardless of where they earn income. If you live in any of the five boroughs, you owe NYC tax on your total income, including NJ wages. NYC tax rates run from 3.078% to 3.876%. The IT-112-R credit applies against New York State tax but does not offset the separate NYC income tax.
How does the IT-112-R credit work?
Form IT-112-R is the New York State resident credit for taxes paid to other jurisdictions. It equals the lesser of the income tax you paid to New Jersey on NJ-source income or the New York tax attributable to that same income. The credit applies to wages and business income but generally excludes interest, dividends, and lottery winnings.
Does New Jersey tax my remote workdays from home in New York?
No. New Jersey taxes nonresidents only on income for services physically performed in the state. Days you work from your New York home are not NJ-source income. This reduces your NJ tax and your IT-112-R credit proportionally, but your total state tax stays roughly the same because that income shifts from NJ taxation to NY taxation.
Does New Jersey have any local income taxes?
No. New Jersey does not impose any local or municipal income tax. Your NJ tax obligation is limited to the state's graduated income tax, with rates from 1.4% to 10.75%. This makes the NJ-NY commute simpler for local taxes than crossings into Pennsylvania, where local earned income taxes can apply to nonresidents.
