<p>I can’t answer for any school but my own. We look at the initial date filed. We encourage our students to file with estimated figures, if necessary. However, we DO have to adjust aid packages if the “real” figures yield a higher EFC. You mentioned that you would be auto 0 either way. Updating your info to the real figures won’t affect your aid, so please don’t worry … go ahead and do it to avoid any future hassles.</p>
