<p>You need to report your income on the FAFSA and the CSS Profile. There are lines for it, just like there are lines for your savings.</p>
<p>You also should file your taxes. Ask your employer if you can be put on the payroll. If not then if your position can be treated as that of an independent contractor, you can file your taxes as self-employed. Your employer can do the paperwork to issue you a 1099, or you can just report the income without that as casual income. The IRS website has lots of help, and the email and telephone helplines are quick this time of year. It really is OK to drop them a line and ask how to do whatever it is that you need to do.</p>
