Self-Employed People Can Pay Taxes At The End Of The Year, Why Can’t I?

I love living on my own and paying my own bills; I get a real sense of accomplishment out of being able to take care of myself. One thing I don’t like is that so much money gets taken out of my paycheck for taxes. I know I get a lot of it back at the end of the year, but I would like for the government to stop withholding taxes, and let me pay them on my own. My sister is self-employed, and she pays her own taxes at the end of the year. I think everyone should have that option, not just the self-employed.
