<p>I have a few questions about tax returns...</p>
<p>1) When they say documents are "due on" or "send by," does this mean it's regarding postmark date or date of sale?</p>
<p>2) We had a paid preparer file our tax return, but we only receive a copy of which he did not sign. Is it necessary to sign the tax return for IDOC and other financial aid sites?</p>
<p>3) Are my parents required to sign the tax return copy even though it's not self-prepared. If so, where do they sign? Do I need both parents?</p>
<p>Thanks!</p>
