Moved from California to Arkansas Mid-Year: Which State Tax Returns Do You File?
Answer
You file two part-year returns. California taxes the income you received while you lived there, Arkansas taxes the income you received after the move, and each state prorates your deductions and credits to its own slice of the year. The date you changed domicile is the dividing line.

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 · CaliforniaForm 540NR (part-year resident)
File a California part-year return covering the months you lived in California. A part-year resident of California reports the income received while a California resident, plus any California-source income received during the rest of the year, and prorates the deductions and credits to the residency period.
- 2Part-year return · ArkansasForm AR1000NR (part-year resident)
File a Arkansas part-year return covering the months you lived in Arkansas. A part-year resident of Arkansas reports the income received while a Arkansas resident, plus any Arkansas-source income received during the rest of the year, and prorates the deductions and credits to the residency period.

- Remote worker: California → ArkansasHome state only
- 1099 contractor: California → ArkansasHome state, plus the client state if you work there

Questions people actually ask
I moved from California to Arkansas mid-year. Do I have to file in both states?
You file two part-year returns. California taxes the income you received while you lived there, Arkansas taxes the income you received after the move, and each state prorates your deductions and credits to its own slice of the year. The date you changed domicile is the dividing line.
How do I split my income between California and Arkansas?
By when you received it, measured against the date your domicile actually changed. Income received while you were a California resident belongs on the California return and income received afterwards on the Arkansas 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.
