State tax filing

@DanielV01 Just checking the info in this thread is still correct for tax year 2020. Thinking that IL won't allow a tax credit for income taxed by another state if it was *also* IL income, so no more tax credit in this situation?

 

Situation: NY employer, working remotely from IL, income taxed by NY (based on employer/office location) and also by IL (based on home/place where remote work is performed).

 

Tried to figure this out based on the tax forms -- IL 2020 Schedule CR instructions for Column B, Line 1: "Enter the amount of wages not shown as Illinois wages on the state copy of the W-2 form(s) you received. Do not include wages taxed by another state if they are also shown as Illinois wages." Wouldn't that result in the tax credit being denied?
