Do I Need To Include My Earned Income?

I hope that someone here can help me. In 2006, I only made a total of $217.50. There was only a total of $10.00 taken out of my checks for federal income tax, and nothing for state. I still have not recieved a W2 and I was wondering if I am even going to recieve one? And if I even have to file taxes with those earnings? Will I get in trouble if I just file taxes and do not include my earnings? My and my husband file jointly, as he is the main wage earner. Thanks.
