New Jersey tax residency rules
Threshold: 183 days · Days + Abode · Calendar year (Jan 1 – Dec 31)
New Jersey's top marginal rate is 10.75%, among the highest in the US. NJ's residency tests are domicile-based plus a statutory residence rule (abode + 184 days), mirroring NY. NJ aggressively audits departing residents, especially former NYC commuters. NJ-PA reciprocity simplifies some scenarios but doesn't extend to NY.
- Statutory residence: NJ abode + 184+ days = full resident, no domicile defense.
- Newark Airport (EWR) layovers count if you cleared TSA on a NJ-origin flight.
- The Division of Taxation will request cell records, EZ-Pass, and credit-card data on audit.
