I was filing Federal and State (IL) returns for my mother-in-law and father-in-law. My mother-in-law passed away last April. They are required to file a return in IL, but they neither owe the State, or get a refund. TurboTax states that the Illinois tax forms cannot be e-filed, due to the need to fill out "Form IL-1310 Statement of Person Claiming Refund Due to Deceased Taxpayer". Under the "Who must complete this form?" section of IL-1310, the second sentence states "However, if you are a surviving spouse filing a joint return with your deceased spouse, do not complete this form."
So if there is no need to fill out the form for the State of IL due to 1) no refund being claimed, and 2) Surviving spouse is filing the taxes and does not need to complete, then why can't we e-file the taxes?
Looks like a missed revenue opportunity for TurboTax!
