Remote worker in CT

matteustax — Tue, 24 Feb 2026 07:27:26 GMT

Hello,

I reside in CT and work remotely for an employer in IL.

Do I have to pay income State taxes for the state of IL?

Could you point me to the official documentation?

Thank you

To clarify @NCperson 's answer, W-2 income is sourced where the work is actually (physically) performed. If your work was actually performed in CT, it is CT-source income, not IL-source income. The employer's location is irrelevant.

Illinois taxes non-residents only on Illinois-sourced income.

Finally, make sure your employer withholds CT state taxes for you, not Illinois state taxes. If your employer does not withhold CT taxes, you'll have to make quarterly estimated tax payments to CT.
