What crossing the line costs
credit covers itDelaware charges more, so its credit covers everything Maryland 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
- Crossing into Maryland for work does not raise your state tax at all. Delaware asks for more than Maryland does, so the credit it gives you absorbs the whole Maryland bill. You end the year at $2,763 either way. The one thing the commute does cost you is a second tax return.
- Counting only the larger flows, 7 states send workers into Maryland. Delaware comes in at number 4 with 28,064 jobs, so this crossing is common enough to be routine for payroll departments there.
- Both states tax these wages and the commuter pays no more than they would have at home. Maryland takes its non-resident share first — $2,486 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.
- Maryland draws commuters of this scale from 7 states, and Delaware ranks number 4 among them with 28,064 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
- What you see here is state tax between Delaware and Maryland. Cities can charge their own tax on top, and a handful do. That layer is not modeled on this page, so treat these figures as the floor rather than the final bill.
- Two assumptions sit under this page. First, that Maryland 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.
- 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 Delaware and Maryland 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 Maryland or Delaware carries a local layer is a separate question from the state arithmetic above.
- The arithmetic assumes all wages are earned in Maryland 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 Maryland portion, computed as a ratio rather than the straightforward cap used above. It also assumes days are worked in Maryland 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 Maryland 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 Maryland'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 Maryland?
Both states tax the same wages, and then one of them backs off. Maryland taxes what you earn inside it. Delaware taxes you on everything, then subtracts what Maryland already took, up to the size of its own bill. You end up paying the larger of the two, which is $2,763 a year on this route.
Does working in Maryland cost me anything extra?
Nothing extra, on this route. You end the year owing $2,763, exactly what you would owe if the job were in Delaware. That is not true of every crossing — plenty of them do cost money — but this one does not. What it does cost you is time at tax filing, because two states may each want a return.
Do I have to file tax returns in both Delaware and Maryland?
Expect two. Living in Delaware means filing there on everything you earn. Working in Maryland 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 Delaware some days instead of going to Maryland?
Normally, days worked at home in Delaware belong to Delaware, and only the days you spend in Maryland 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 Maryland'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 — Maryland 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 Maryland'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 Maryland.
What filing obligations arise in each state on this corridor?
Generally two. Delaware requires a resident return reporting all income; Maryland 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 Maryland'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 Maryland throughout.
