Illinois Tax Return

[user17759303457]

Husband was a full-year resident of Illinois, and wife was a part-year resident (3 months) of Illinois in 2025. We filed jointly for our federal return. However, the residence information entered in the Personal Info section of TurboTax did not carry over correctly to the Illinois return.

In the Illinois section, the form only allows entry of either the husband’s or the spouse’s residency information—not both. As a result, the Illinois return is showing both taxpayers as either full-year residents or part-year residents, which is incorrect.

Please advise on how to properly reflect different residency statuses for each spouse and resolve this issue in Turbo Tax. Thanks!

@user17759303457 you have the option of each filing Separate or  Filing Joint in Illinios since you both were not full year residents. 

if you choose to file file MFS , you would file MFS, with a residential tax return.  Your spouse would file MFS with a part year tax return.

Alternatively, you can file MFJ and then take a tax credit for what your wife paid in the other state.

Federal section

in the personal worksheet for your spouse, it asks for the state of residency on 12/31/2025? did you answer this

 then it asks if she was a part-year resident of that state for which you should check the box

then it asks for the date residency was established in that state enter the date 

then it asks for the previous state of residency for which you should enter IL. 

in the Illinois info worksheet check part-year resident. But there's a bug as you noticed because it only asks for one of the taxpayers. the actual Il-1040 does not ask it this way. Rather on form Il-1040-NR each of you enter your dates of illinois residency and for your spouse the other state and dates of residency.
