Live in Maryland, Work in Delaware: Which State Taxes Your Paycheck?
Answer
Delaware withholds and Maryland credits. Without an agreement between them, both states are entitled to tax income earned in Delaware by a Maryland resident. The mechanism that stops you paying twice is the credit on the Maryland resident return, which is why the Delaware return has to be completed first.

Two states can lawfully tax the same wages: Delaware because the work happened there, Maryland because you live there. Nothing prevents the overlap in advance — it is unwound afterwards, on the Maryland return, through the credit for taxes paid to another state.
A Maryland resident taxed by another state on the same income claims the credit for taxes paid to other states on Form 502CR. The credit is capped at the Maryland tax on that income, so it removes the double tax but never refunds the excess when the other state charges more.
Delaware also has a layer below the state one, and it is the layer that survives every agreement: Wilmington levies a city earned income tax on wages earned inside the city, collected by the city rather than the Division of Revenue.
What you file
- 1Nonresident return · DelawareForm PIT-NON
File the Delaware nonresident return FIRST — you need the Delaware tax figure before you can complete Maryland.
- 2Resident return · MarylandForm 502CR
File a Maryland resident return reporting all income, then claim the credit for tax paid to Delaware. The credit is capped at what Maryland would have charged on that same income, so if Delaware taxes it at a higher rate the difference is not refunded.

Questions people actually ask
I live in Maryland and work in Delaware. Which state takes the tax out of my paycheck?
Delaware withholds and Maryland credits. Without an agreement between them, both states are entitled to tax income earned in Delaware by a Maryland resident. The mechanism that stops you paying twice is the credit on the Maryland resident return, which is why the Delaware return has to be completed first.
Which state should my employer be withholding for?
Delaware. The wages are sourced to Delaware, so Delaware withholding is correct and there is no Maryland withholding to set up.
Will I end up paying tax twice on the same income?
Not twice over, but you will pay the higher of the two rates. Maryland gives residents a credit for tax paid to Delaware on the same income, claimed on Form 502CR. The credit is capped at the Maryland tax on that income, so if Delaware taxes it more heavily the excess is not refunded by either state.
