IDOC deadlines?

<p>Quick question from a student.
The colleges I'm applying to have a deadline of March 1st for IDOC. So what does that mean exactly? The postmark date of mailing it to collegeboard? The date they get it? If the latter, how do we even know when to send it? Thanks in advance!
(Of course, the best answer would be send it asap but we still have to file our taxes..so.. we'll probably be close to the deadline)</p>

<p>I think if your colleges require that they must have all tax documents by March 1 then you must send your documents to IDOC before that date so that they can scan them for your colleges to use. You can call the colleges to clarify.</p>
