What crossing the line costs
credit covers itDelaware charges more, so its credit covers everything New Jersey takes. Both states collect; your total does not change. Solid is what you actually pay; the faded part of the Delaware 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
- Delaware is the dearer of these two states, and that works in your favor here. Whatever New Jersey takes out of your pay comes straight back off your Delaware bill. The total lands at $2,763, which is exactly what you would owe with a job at home. Do not mistake that for being untaxed by New Jersey — it takes $1,767, and Delaware simply covers it.
- Delaware is one of 5 states sending this many workers into New Jersey, and it sits at number 3 of them, with 10,838 jobs. States used to handling out-of-state workers usually make the filing side of it straightforward.
- Both states tax these wages and the commuter pays no more than they would have at home. New Jersey takes its non-resident share first — $1,767 at the reference salary — and Delaware, whose own liability on the same income is the larger of the two, credits that amount in full and collects the balance. The total is $2,763, identical to what an earner living and working in Delaware would owe. ⚠️ The money is split between two treasuries rather than reduced, which matters at filing time: two state returns, not one.
- New Jersey draws commuters of this scale from 5 states, and Delaware ranks number 3 among them with 10,838 jobs. A work state pulling from that many directions tends to have a well-established non-resident filing routine, which is a practical convenience rather than a tax saving.

What this page does not cover
- One thing this page leaves out: city taxes. Some cities charge their own tax on people who work there, and it sits on top of everything above. Philadelphia is the well-known one. New York City only charges its own residents, so commuting in adds nothing. Check whether the city you work in is one that charges, because the New Jersey state figure is not the whole story if it does.
- Two assumptions sit under this page. First, that New Jersey is where all your pay comes from. Second, that you go there rather than working from your kitchen in Delaware. Mixed income changes how the credit is worked out, and remote days have their own rules in some states.
- Every dollar figure here uses a salary of sixty thousand a year. It is a stated benchmark, not a guess at what people on this route earn. Scale them to your own pay. Which state ends up dearer, Delaware or New Jersey, generally holds at other salaries — though the gap between them can widen or narrow as you cross tax brackets.
- 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 New Jersey or Delaware carries a local layer is a separate question from the state arithmetic above.
- The arithmetic assumes all wages are earned in New Jersey and that there is no other income. That matters for the credit: where income comes from several states, Delaware limits the credit to the share of its own tax attributable to the New Jersey portion, computed as a ratio rather than the straightforward cap used above. It also assumes days are worked in New Jersey 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 Delaware to New Jersey 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 New Jersey'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 Delaware and New Jersey?
You file in both states, but you do not pay the full amount to both. Delaware credits the tax New Jersey collected, capped at its own charge on that income. The practical result is one bill at the higher of the two levels: $2,763 for the year.
Does working in New Jersey cost me anything extra?
No. The state line is real on a map and invisible on your pay stub here. Your total is $2,763 either way. Keep the paperwork in mind though: crossing a line usually means filing twice even when it changes nothing.
Do I have to file tax returns in both Delaware and New Jersey?
Usually yes, and it catches people out. Delaware wants a return because you live there. New Jersey 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 Delaware some days instead of going to New Jersey?
It depends on the state, and the answer is not the one most people expect. You might assume a day worked at your kitchen table in Delaware is taxed by Delaware. Usually that is right, and your New Jersey share shrinks to the days you were actually there. But a few states tax days you work at home as though you had been in the office, unless your employer required you to be elsewhere. It is worth checking which kind New Jersey is before assuming.
How is liability allocated between residence and work state on the same wages?
Both jurisdictions assert a claim on the same wages — New Jersey on a source basis, Delaware 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, $2,763 at the reference salary, and the split between the two treasuries is the only thing the credit changes.
Why is the marginal state-tax cost of this crossing zero?
Marginal cost is zero because the binding liability is the residence state's. Delaware's own charge on this income equals or exceeds New Jersey's, so the resident credit absorbs the source-state tax entirely and combined liability equals residence-only liability, $2,763. ⚠️ Zero marginal tax is not zero obligation: a non-resident return may still be required in New Jersey.
What filing obligations arise in each state on this corridor?
Generally two. Delaware requires a resident return reporting all income; New Jersey 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 Delaware fall outside New Jersey'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 New Jersey throughout.
