If your wages were reported on a W-2 and you did not have any taxes withheld then you do not need to file a tax return.
However, if the income was from self-employment and you did not receive a W-2 then you will have to file, since the income was $400 or more. You will have to report the self-employment income and expenses on a Schedule C which is included with the federal tax return, Form 1040.
