Fica Calculator I Am A Dependent, Help With Taxes?

I am a Dependent, help with taxes? - fica calculator

I am 17 years old, I live in California and I $ 8,700 in 2006.
My parents are my dependent.
I know that the threshold for the dependent variable is $ 4400 for taxes?

Now I have my salary before me and I remember my boss if I am working to reduce some of my taxes on my salary because I had expected to begin earning less than the threshold of 4400th I'm fed WT "to cut it, now does not pay directly from my salary. I paid the FICA and CA DIS in its entirety.

Is there a calculator or a simple way to know how much more (or less?) I owe the IRS?

Thanks
