Moved from Texas to Colorado Mid-Year: Which State Tax Returns Do You File?
Answer
Colorado taxes the second half of the year. Texas has no personal income tax, so the pre-move income is untouched at state level; the Colorado part-year return picks up from the date you became a Colorado resident and prorates your deductions to that stretch.

Questions people actually ask
I moved from Texas to Colorado mid-year. Do I have to file in both states?
Colorado taxes the second half of the year. Texas has no personal income tax, so the pre-move income is untouched at state level; the Colorado part-year return picks up from the date you became a Colorado resident and prorates your deductions to that stretch.
How do I split my income between Texas and Colorado?
By when you received it, measured against the date your domicile actually changed. Income received while you were a Texas resident belongs on the Texas return and income received afterwards on the Colorado return. Keep evidence of the move date — a lease, a closing statement, a licence issue date.
