What crossing the line costs
costs youDelaware 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
- Crossing this line costs money. Delaware taxes what you earn there. New Jersey taxes you too, because you live there, and then gives you credit for what Delaware already took. The catch is the size of that credit. It stops at what New Jersey would have charged on its own. So you end up paying the bigger of the two bills, which here means $2,763 a year instead of $1,767. The commute itself accounts for $996 of that.
- 14,355 jobs is the size of this crossing from New Jersey into Delaware. Smaller than the famous ones, and governed identically. The only practical difference is familiarity — fewer people at your workplace will have done this before.
- Delaware 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 Delaware 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 $2,763 against $1,767 for the same earner working at home — $996 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 Delaware changes the split between the two treasuries and not the total.
- This is a smaller corridor by national standards — 14,355 jobs in Delaware 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
- 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 Delaware state figure is not the whole story if it does.
- These numbers assume the job in Delaware is your only income, and that you actually go there to work. Both matter. If you earn money in more than one state, the credit New Jersey gives is worked out as a share rather than the simple cap used here. And if you work from home some days, some states have rules that treat those days as worked at the office anyway.
- 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 Delaware 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 Delaware or New Jersey carries a local layer is a separate question from the state arithmetic above.
- The arithmetic assumes all wages are earned in Delaware 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 Delaware portion, computed as a ratio rather than the straightforward cap used above. It also assumes days are worked in Delaware 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 Delaware 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 Delaware'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 Delaware?
Not twice over. Both states have a claim — Delaware because you earn the money there, New Jersey because you live there — but New Jersey gives you credit for what Delaware took. The credit stops at what New Jersey would have charged on its own, so what you actually pay is the bigger of the two bills. Here that comes to $2,763 for the year.
Would moving out of New Jersey lower my state tax if I keep working in Delaware?
Probably not, and this is the part people get wrong. Delaware 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 Delaware?
Expect two. Living in New Jersey means filing there on everything you earn. Working in Delaware usually means filing there as well, on the part you earned inside it. The second one is often how the credit gets claimed, so skipping it can cost you money you are owed.
What if I work from home in New Jersey some days instead of going to Delaware?
Working from home usually moves that day's pay out of Delaware and into New Jersey alone. A handful of states disagree and tax remote days as if you had commuted. This page assumes you actually travel to Delaware, so if a lot of your week is at home the split will differ from what you see here.
How is liability allocated between residence and work state on the same wages?
Both jurisdictions assert a claim on the same wages — Delaware 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, $2,763 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. Delaware'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 Delaware'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; Delaware 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 Delaware'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 Delaware throughout.
