IDOC and tax returns

<p>We have filled FAFSA & CSS for our daughter.
But for the IDOC, still have not received all the 1099 forms to finish our taxes.</p>

<p>Is it ok to send just the W2 and the existing 1099 forms with the IDOC for the mar 1st deadline ?</p>

<p>WHat should we do if taxes cannot be filed?</p>
