Key fact: NY and NJ do NOT have a formal tax reciprocity agreement (unlike some state pairs). However, both states offer credits for taxes paid to the other state, preventing true double taxation for residents who work across the border.

How the Taxes Work
A detailed explainer on how NY and NJ handle income earned by each other's residents, including the credit mechanism, filing requirements, and common mistakes.
NY and NJ do NOT have a formal tax reciprocity agreement (unlike some state pairs). However, both states offer credits for taxes paid to the other state, preventing true double taxation for residents who work across the border.
The critical distinction is NYC residency. New York City imposes a local income tax ranging from 3.078% to 3.876% on city residents. This tax does not apply to people who merely work in NYC — it applies only to those who live there. As a result, any commuter living outside the five boroughs is automatically exempt, regardless of how many hours they spend in a Manhattan office.
What You Owe: Tax Breakdown at $100,000
Here is how the actual tax math looks for two workers earning $100,000 — one living in NYC, one commuting from outside the city.
NYC Resident at $100,000
Non-Resident at $100,000
The non-resident saves $3,441/year at $100,000 simply by not being an NYC resident — that is the NYC local income tax that residents pay and non-residents do not.
Frequently Asked Questions
Do NY and NJ have a reciprocity agreement?
No. Unlike states such as PA and NJ (which do have reciprocity), NY and NJ do not. An NJ resident working in NY must file both an NY non-resident return and an NJ resident return. NJ then gives a credit for taxes paid to NY.
What forms do I need as an NJ resident working in NY?
File Form IT-203 (NY Non-Resident and Part-Year Resident Income Tax Return) for NY, and Form NJ-1040 for NJ. On the NJ return, claim the credit on Schedule A using the taxes paid to NY.
Can I end up owing money to both states?
In most cases, no — the NJ credit for NY taxes eliminates most double taxation. However, if NJ taxes certain income types differently (e.g., pension income, deductions), you may owe a small amount to NJ even after the credit.
