FAQ
Illinois-specific questions
I left Illinois for Dubai — am I still a Illinois resident for tax?
Illinois uses a long-established flat-rate income tax; residency follows domicile, and part-year returns cover departure years. We run a residency review as the first step of every Illinois engagement, so your state position is deliberate, not accidental.
What does the Illinois return involve alongside my federal filing?
Illinois-source income and part-year rules drive the state return; it is prepared together with your 1040 so the two never contradict each other. The state return is an add-on to your federal engagement, quoted after the residency review.
Illinois + federal, one desk.
One call reviews your residency position and quotes both returns — fixed, in writing.
