Moving to or From CT? Tax Checklist
Moving to or from Connecticut? This part-year resident tax checklist explains which CT return you'll file, what income CT taxes, and what to update. Checked November 3, 2026.
For general education only. Not tax, legal, insurance, or investment advice, and not a promise of any result. Tax rules and due dates change, so confirm with the IRS (irs.gov), the CT Department of Revenue Services (portal.ct.gov/DRS) or your town before you act, and ask your tax preparer about your own situation.
What changes for your taxes
- Part-year resident: if you changed your permanent legal home (domicile) by moving into or out of Connecticut during the year, you're a part-year resident and file Form CT-1040NR/PY if a filing test is met (CT DRS).
- What CT taxes: your income for the part of the year you were a resident, plus Connecticut-source income for the nonresident part. You'll complete Schedule CT-1040AW (CT DRS).
- You'll likely file in two states. Keep track of the exact move date and when each paycheck changed states.
What to do before December 31, 2026
- To do Write down your move date and keep proof (lease, closing papers, utilities).
- To do Update your address with the IRS (Form 8822) and with your employer (IRS).
- To do Ask your employer to switch your state withholding and give them a new CT-W4 if needed.
- To do Health coverage: moving to Connecticut is a qualifying life event at Access Health CT (Access Health CT).
The Connecticut side
- Domicile is the place you intend as your permanent home. It doesn't change until you move and intend to stay (CT DRS).
- If one spouse is a CT resident and the other is a nonresident or part-year resident, CT has special rules that can require filing separately for CT. Check CT DRS guidance or ask your tax preparer.

Does Connecticut tax income I earned before I moved here?
For a part-year resident, Connecticut taxes income from the resident period plus Connecticut-source income from the nonresident period.
Can a part-year resident file as a full-year Connecticut resident?
