<p>My parents haven't filed for 2011 income tax return yet, so we're just estimating the numbers from our 2010 IRS. If I were to submit my CSS now, can I go back and update it after my parents have filed for their taxes like on the FAFSA? If not, how would the colleges know that the information I provided is correct? After all I only used estimates...</p>
<p>You cannot update the Profile online. You can submit it with estimates but you will need to contact each college to find out their procedure for updating Profile info. They will tell you what to do at each school.</p>
