The full explanation
In general you must file if your gross income is above the minimum the IRS sets for your filing status, or if you had a certain amount of net earnings from self-employment; even when you do not have to, filing can pay off. You need your SSN or ITIN, and those of everyone else on the return, plus documents such as your W-2s and 1099s.
An example
Every spring, Andrea gathers her W-2 and the 1099s from her side jobs and prepares her tax return for free at a VITA site.
