Helping my son file his taxes for the first time. He is filing for the first time in Illinois and needs to snail mail in his IL-1040. TurboTax only had us print the IL-1040, but do we need to include his electronically filed Federal 1040 in the snail mail as well? I cannot find a direct answer online - or one that makes sense to me at least.
Yes. When you mail a return to IL they want a copy of the federal too. When you choose to file by mail, the pages you need to mail will print out for you.
Thank you. I appreciate it.
I was confused since TurboTax only had me print the IL-1040. It was odd as we got all the way to sending the returns via eFile and TurboTax popped up a notice stating we had to mail in the IL return, but filed his Federal and MO State Returns electronically.
