Anyone have an idea of how much income taxes I have to pay in NYC??

I just got a job and get paid about $32,000 a year. I am single and 24 years old. I have no dependants. I thought that I would have to pay around 30% but someone told me that I'll have to pay like 45% of my income to the government which is ridiculous (I hope). Anyone out there know a rough estimate?? I will not be able to sleep if that 45% figure is true.. so for anyone who can either relate or know what they're talking about, please give me some information. Thanks.
