Live in California, Work in Louisiana: Which State Taxes Your Paycheck?
Answer
Both states tax the same wages, and a credit undoes the overlap. Louisiana withholds as your work state and you file a Louisiana nonresident return; California taxes residents on all income, so you also file at home and claim the credit for tax paid to Louisiana. File Louisiana first.

Two states can lawfully tax the same wages: Louisiana because the work happened there, California because you live there. Nothing prevents the overlap in advance — it is unwound afterwards, on the California return, through the credit for taxes paid to another state.
A California resident taxed by another state on the same income claims the credit for taxes paid to other states on Schedule S. The credit is capped at the California tax on that income, so it removes the double tax but never refunds the excess when the other state charges more.
What you file
- 1Nonresident return · LouisianaForm IT-540B
File the Louisiana nonresident return FIRST — you need the Louisiana tax figure before you can complete California.
- 2Resident return · CaliforniaSchedule S
File a California resident return reporting all income, then claim the credit for tax paid to Louisiana. The credit is capped at what California would have charged on that same income, so if Louisiana taxes it at a higher rate the difference is not refunded.

Questions people actually ask
I live in California and work in Louisiana. Which state takes the tax out of my paycheck?
Both states tax the same wages, and a credit undoes the overlap. Louisiana withholds as your work state and you file a Louisiana nonresident return; California taxes residents on all income, so you also file at home and claim the credit for tax paid to Louisiana. File Louisiana first.
Which state should my employer be withholding for?
Louisiana. The wages are sourced to Louisiana, so Louisiana withholding is correct and there is no California 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. California gives residents a credit for tax paid to Louisiana on the same income, claimed on Schedule S. The credit is capped at the California tax on that income, so if Louisiana taxes it more heavily the excess is not refunded by either state.
