What crossing the line costs
costs youConnecticut charges more than New Jersey would, and New Jersey only credits you up to its own bill — so the difference stays with you. Solid is what you actually pay; the faded part of the New Jersey bar is the credit it hands back. State income tax only — federal and payroll tax apply on top, and a city wage tax may too.
Which state taxes you, and what it costs
- Here is the thing people get wrong about New Jersey and Connecticut. Moving somewhere cheaper does not help if the job stays put. The state where you work takes its share first, and your home state only refunds up to what it charges itself. That leaves $783 a year that exists purely because the job is across the line. All in, $2,550.
- This is not one of the country's big crossings. 9,096 jobs in Connecticut are held by people living in New Jersey. The tax rules do not care about that — they are the same ones that apply to the busiest routes in the country. What can differ is how used to the paperwork your employer is.
- Connecticut taxes wages earned inside its borders by non-residents, and New Jersey taxes its residents on the same wages wherever they are earned. The resident credit resolves the overlap but does not erase it: New Jersey credits tax paid to Connecticut only up to what it would itself have charged on that income, so the commuter settles at the higher of the two liabilities rather than the sum. At the reference salary that is $2,550 against $1,767 for the same earner working at home — $783 attributable to the state line itself. ⚠️ The corollary is the part most readers have backwards: moving to a cheaper home state while keeping the job in Connecticut changes the split between the two treasuries and not the total.
- This is a smaller corridor by national standards — 9,096 jobs in Connecticut held by New Jersey residents — but the rules that govern it are the same rules that govern the largest ones. Corridor size changes how familiar an employer's payroll department is with the paperwork, never the tax treatment.

What this page does not cover
- City wage taxes are not in these numbers. A few places charge them, and where they do the money is real. If your job in Connecticut is inside a city that taxes workers, add that on top. Where it is not, the state figures above are the whole of it for New Jersey residents.
- Two assumptions sit under this page. First, that Connecticut is where all your pay comes from. Second, that you go there rather than working from your kitchen in New Jersey. Mixed income changes how the credit is worked out, and remote days have their own rules in some states.
- Sixty thousand a year is the assumption behind these amounts, chosen because nobody publishes average pay for a route between two states. At your own salary the numbers shift. The conclusion about which of New Jersey and Connecticut takes more usually does not, but the size of the difference can.
- These figures cover the STATE layer only. City and municipal wage taxes sit on top of them and are not included: a commuter into Philadelphia pays its wage tax on top of anything here, and Ohio's municipalities run their own credit system, which this site models in its own families. New York City, by contrast, taxes only its residents, so a commuter into it adds nothing at the city level. Whether Connecticut or New Jersey carries a local layer is a separate question from the state arithmetic above.
- The arithmetic assumes all wages are earned in Connecticut and that there is no other income. That matters for the credit: where income comes from several states, New Jersey limits the credit to the share of its own tax attributable to the Connecticut portion, computed as a ratio rather than the straightforward cap used above. It also assumes days are worked in Connecticut rather than remotely — several states tax a non-resident's remote days as though they were worked at the employer's location, which reverses the usual expectation and is handled on this site's reciprocity pages.
- Dollar amounts are computed at a stated reference salary of sixty thousand rather than a corridor wage average, which no published source provides per state pair. Because both states' liabilities and the credit between them are functions of the same income, the direction of the New Jersey to Connecticut comparison holds at other salaries even though the amounts do not — with one qualification worth stating, that a progressive schedule can change the SIZE of the gap at higher incomes, and in Connecticut's case a bracket crossed on one side and not the other is exactly where that happens.
Questions people ask
Do I pay state tax twice, to New Jersey and Connecticut?
Both states tax the same wages, and then one of them backs off. Connecticut taxes what you earn inside it. New Jersey taxes you on everything, then subtracts what Connecticut already took, up to the size of its own bill. You end up paying the larger of the two, which is $2,550 a year on this route.
Would moving out of New Jersey lower my state tax if I keep working in Connecticut?
Probably not, and this is the part people get wrong. Connecticut taxes the wages because that is where you earn them, whoever you are and wherever you sleep. Your home state only ever credits you up to its own bill. So moving somewhere cheaper changes which government keeps the money, not how much leaves your pay. What would change it is the job moving, not you.
Do I have to file tax returns in both New Jersey and Connecticut?
Usually yes, and it catches people out. New Jersey wants a return because you live there. Connecticut usually wants one too, because you earned money inside it — even in the cases where you end up owing it nothing. Filing in a state and paying it are separate things, and the return is often what proves you do not owe.
What if I work from home in New Jersey some days instead of going to Connecticut?
Normally, days worked at home in New Jersey belong to New Jersey, and only the days you spend in Connecticut are taxed there. That is the ordinary rule. The exception is real though: some states count your remote days as worked at the employer's location anyway. That flips the answer completely, so check Connecticut's rule rather than assuming.
How is liability allocated between residence and work state on the same wages?
Both jurisdictions assert a claim on the same wages — Connecticut on a source basis, New Jersey on residence. The residence state grants a credit for tax paid to the source state, limited to the residence state's own liability on that income. Net combined liability therefore equals the greater of the two liabilities rather than their sum, $2,550 at the reference salary, and the split between the two treasuries is the only thing the credit changes.
Does changing residence reduce combined liability while the work state is unchanged?
No, while the source state is unchanged. Connecticut's claim arises from where the services are performed and is unaffected by residence. Because the residence credit is capped at the residence state's own liability, combined liability equals the greater of the two — so substituting a lower-tax residence reduces the residence-state component toward zero while leaving the total at Connecticut's level. The binding variable is the work location, not the home one.
What filing obligations arise in each state on this corridor?
Generally two. New Jersey requires a resident return reporting all income; Connecticut requires a non-resident return reporting the income sourced to it, which is also the mechanism by which the resident credit is substantiated. ⚠️ A filing obligation is distinct from a liability: a reciprocity exemption or a zero net position removes tax without necessarily removing the return, and the non-resident return is frequently what establishes the credit claimed on the resident one.
How do remote working days affect sourcing between these two states?
Ordinarily wages are sourced to where the services are performed, so days worked remotely from New Jersey fall outside Connecticut's jurisdiction and the source-state apportionment shrinks accordingly. ⛔ The exception is the "convenience of the employer" rule, which several states apply: a non-resident's remote days are sourced to the employer's location unless the remote work is required by the employer rather than chosen by the employee. The figures on this page model in-person attendance in Connecticut throughout.
