Live in Louisiana, Work in Kentucky: Which State Taxes Your Paycheck?
Answer
Two returns, one credit. Kentucky has the first claim on wages earned inside the state and withholds accordingly. Louisiana then taxes you as a resident on everything and gives credit for what Kentucky already took, capped at what Louisiana would have charged on that same income.

Two states can lawfully tax the same wages: Kentucky because the work happened there, Louisiana because you live there. Nothing prevents the overlap in advance — it is unwound afterwards, on the Louisiana return, through the credit for taxes paid to another state.
A Louisiana resident taxed by another state on the same income claims the credit for taxes paid to other states on Schedule G (Form IT-540). The credit is capped at the Louisiana 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
- 1Nonresident return · KentuckyForm 740-NP
File the Kentucky nonresident return FIRST — you need the Kentucky tax figure before you can complete Louisiana.
- 2Resident return · LouisianaSchedule G (Form IT-540)
File a Louisiana resident return reporting all income, then claim the credit for tax paid to Kentucky. The credit is capped at what Louisiana would have charged on that same income, so if Kentucky taxes it at a higher rate the difference is not refunded.

- 1099 contractor: Louisiana → KentuckyHome state, plus the client state if you work there
- Moved mid-year: Louisiana → KentuckyTwo part-year returns

Questions people actually ask
I live in Louisiana and work in Kentucky. Which state takes the tax out of my paycheck?
Two returns, one credit. Kentucky has the first claim on wages earned inside the state and withholds accordingly. Louisiana then taxes you as a resident on everything and gives credit for what Kentucky already took, capped at what Louisiana would have charged on that same income.
Which state should my employer be withholding for?
Kentucky. The wages are sourced to Kentucky, so Kentucky withholding is correct and there is no Louisiana 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. Louisiana gives residents a credit for tax paid to Kentucky on the same income, claimed on Schedule G (Form IT-540). The credit is capped at the Louisiana tax on that income, so if Kentucky taxes it more heavily the excess is not refunded by either state.
