<p>OK, my parent had tax return which means every data is solid now. </p>
<p>I know some colleges request another due date for the corrected FAFSA, CSS and the proof of tax return(1040 or W-2...etc.).</p>
<p>If there is no another due date, do I need to send the corrected FAFSA and CSS asap anyway?</p>
<p>or can I wait until an admission letter around April?</p>
