<p>I remember people saying after you do your taxes you need to update something. Is it FAFSA AND CSS you have to update or just one of them?</p>
<p>When you update it do you update everything that has changed from last tax return to the new tax return. </p>
<p>ALSO do you have to resend the FAFSA to all the schools again? Will this cost money?</p>
<p>Yes you have to update FAFSA and CSS to reflect your actual tax returns. FAFSA can be updated online. FAFSA does not cost anything to submit the first F in FAFSA stands for Free. You should send it to all your schools (or at the very least the schools you are still interested in attending).</p>
<p>CSS can not be updated online. It has to be done by mail. Check with your school(s) what they require.</p>
