Moved from Louisiana to Alabama Mid-Year: Which State Tax Returns Do You File?
Answer
Both states want a return, but neither taxes the whole year. Moving from Louisiana to Alabama splits the tax year at the date your residency changed: a Louisiana part-year return covers everything before it, a Alabama part-year return everything after. Income is assigned by when it was received.

A mid-year move splits the tax year in two, and each state taxes its own half. That is a residency question, so the machinery that governs commuters — reciprocity agreements, convenience rules, nonresident withholding — is beside the point here.
What you file
- 1Part-year return · LouisianaForm IT-540B
File a Louisiana part-year return covering the months you lived in Louisiana. A part-year resident of Louisiana reports the income received while a Louisiana resident, plus any Louisiana-source income received during the rest of the year, and prorates the deductions and credits to the residency period.
- 2Part-year return · AlabamaForm 40 (part-year resident)
File a Alabama part-year return covering the months you lived in Alabama. A part-year resident of Alabama reports the income received while a Alabama resident, plus any Alabama-source income received during the rest of the year, and prorates the deductions and credits to the residency period.

Same two states, different situation
The withholding answer turns on how you are paid and where the work happens, not only on which two states are involved.
- W-2 commuter: Louisiana → AlabamaBoth states — credit offsets the double tax
- Remote worker: Louisiana → AlabamaHome state only
- 1099 contractor: Louisiana → AlabamaHome state, plus the client state if you work there

Questions people actually ask
I moved from Louisiana to Alabama mid-year. Do I have to file in both states?
Both states want a return, but neither taxes the whole year. Moving from Louisiana to Alabama splits the tax year at the date your residency changed: a Louisiana part-year return covers everything before it, a Alabama part-year return everything after. Income is assigned by when it was received.
How do I split my income between Louisiana and Alabama?
By when you received it, measured against the date your domicile actually changed. Income received while you were a Louisiana resident belongs on the Louisiana return and income received afterwards on the Alabama return, with each state prorating your deductions, exemptions and credits to its own part of the year. Keep evidence of the move date — a lease, a closing statement, a licence issue date.
