Live in Kentucky, Work in Delaware: Which State Taxes Your Paycheck?
Answer
Expect withholding in Delaware and a return in both. Kentucky and Delaware hold no reciprocal agreement, so the overlap is resolved after the fact: Delaware taxes the Delaware-source wages, and your Kentucky resident return claims a credit for that tax against the Kentucky liability on the same income.

Two states can lawfully tax the same wages: Delaware because the work happened there, Kentucky because you live there. Nothing prevents the overlap in advance — it is unwound afterwards, on the Kentucky return, through the credit for taxes paid to another state.
A Kentucky resident taxed by another state on the same income claims the credit for taxes paid to other states on Schedule ITC. The credit is capped at the Kentucky 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 Kentucky.
- 2Resident return · KentuckySchedule ITC
File a Kentucky resident return reporting all income, then claim the credit for tax paid to Delaware. The credit is capped at what Kentucky 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 Kentucky and work in Delaware. Which state takes the tax out of my paycheck?
Expect withholding in Delaware and a return in both. Kentucky and Delaware hold no reciprocal agreement, so the overlap is resolved after the fact: Delaware taxes the Delaware-source wages, and your Kentucky resident return claims a credit for that tax against the Kentucky liability on the same income.
Which state should my employer be withholding for?
Delaware. The wages are sourced to Delaware, so Delaware withholding is correct and there is no Kentucky 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. Kentucky gives residents a credit for tax paid to Delaware on the same income, claimed on Schedule ITC. The credit is capped at the Kentucky tax on that income, so if Delaware taxes it more heavily the excess is not refunded by either state.
