Live in Delaware, Work in Kentucky: Which State Taxes Your Paycheck?

Both states — credit offsets the double taxKentucky withholds

Answer

Both states tax the same wages, and a credit undoes the overlap. Kentucky withholds as your work state and you file a Kentucky nonresident return; Delaware taxes residents on all income, so you also file at home and claim the credit for tax paid to Kentucky. File Kentucky first.

Two states can lawfully tax the same wages: Kentucky because the work happened there, Delaware because you live there. Nothing prevents the overlap in advance — it is unwound afterwards, on the Delaware return, through the credit for taxes paid to another state.

A Delaware resident taxed by another state on the same income claims the credit for taxes paid to other states on Schedule I (Form PIT-RES). The credit is capped at the Delaware tax on that income, so it removes the double tax but never refunds the excess when the other state charges more.

Kentucky also has a layer below the state one, and it is the layer that survives every agreement: Kentucky cities, counties and school districts levy occupational licence taxes on wages earned in their jurisdiction. Reciprocity does not reach them, and the home state's credit generally does not either — a reciprocal-state resident working in Kentucky still pays the local tax.

What you file

  1. 1Nonresident return · KentuckyForm 740-NP

    File the Kentucky nonresident return FIRST — you need the Kentucky tax figure before you can complete Delaware.

  2. 2Resident return · DelawareSchedule I (Form PIT-RES)

    File a Delaware resident return reporting all income, then claim the credit for tax paid to Kentucky. The credit is capped at what Delaware would have charged on that same income, so if Kentucky taxes it at a higher rate the difference is not refunded.

The withholding answer turns on how you are paid and where the work happens, not only on which two states are involved.

Questions people actually ask

I live in Delaware and work in Kentucky. Which state takes the tax out of my paycheck?

Both states tax the same wages, and a credit undoes the overlap. Kentucky withholds as your work state and you file a Kentucky nonresident return; Delaware taxes residents on all income, so you also file at home and claim the credit for tax paid to Kentucky. File Kentucky first.

Which state should my employer be withholding for?

Kentucky. The wages are sourced to Kentucky, so Kentucky withholding is correct and there is no Delaware 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. Delaware gives residents a credit for tax paid to Kentucky on the same income, claimed on Schedule I (Form PIT-RES). The credit is capped at the Delaware tax on that income, so if Kentucky taxes it more heavily the excess is not refunded by either state.
