Payroll taxes are a given. State Income taxes, Federal Income Taxes, Social Security Tax, Medicaid Tax, probably in the neighborhood of the 30% Kukri mentioned. When you file a tax return next year, at your probable income level, you'll get most of it back. Death and taxes, get used to it.

I would kindly suggest that you get into the habit of paying yourself first. Even if you only start out saving $20 a week, it will add up over time and you'll not even miss it after awhile. We all tend to adjust our lifestyle and spending habits to what we take home each payday, learning to save and invest a portion of your wages is an important life skill. You could use it for college or trade school, to buy a car or whatever. Don't put it off, compounding interest over time at your young age can really add up.
