<p>Do both parents need to sign the tax returns submitted to individual colleges and to IDOC?</p>
<p>If both signed the returns when they were sent into the govt, then they should both sign for IDOC purposes.</p>
<p>Okay, thanks.</p>
<p>One more question. Is just signing the tax return sufficient, or do all schedules need to be signed as well?</p>
<p>no, it’s just the 1040 (2nd page) that has the signatures.</p>
