Do we need to file an Illinois Tax Return because we received a Illinois Schedule K-1-T, although we file a Wisconsin Tax Return because that is where we live and work?

Sister-in-law passed away in 2018.  She lived in Illinois.  We live and work in Wisconsin.  Her Estate sent us a Illinois Schedule K-1-T.  Do we need to file an Illinois Tax Return as well as our normal Wisconsin Tax Return?

Yes, if you received a K-1 for an estate/trust that is from another state, you will need to file a non-resident return for that state (Illinois) and report the Illinois K-1 income only.  TurboTax recommends that you complete the non-resident return first so that you may received credit for any taxes due/paid to the non-resident state on your resident (WI) return.

Below is more information about filing a non-resident return:
