Curvkyle,

I'm going to try to answer this as best I can. Amount taxed varies from state to state, income to income, marital status to single status, and the list continues. There are a few shelters some people are able to capitalize on, such as making a minimal amount from the freelance that allows you to be untaxed, but it ultimately boils down to each individual situation.

For example, let's say you earn 3x as much than your regular job pays you, are single, live in an apartment, have no children, don't give to charities or any sort, and have relatively "impulse" shopping habits. You will be a christmas gift to the IRS. In California, someone in that position would be taxed up to 40% I believe?

Now, that situation could easily change.. it depends on yours. Take into account who you earn more with.. also take into account that as a freelancer, which in some states I believed is taxed as a "sole propietorship," you need to earn a significant amount before any significant taxes are called for...

Unless you are a single high roller, you should be fine. That's the best I can do, sorry
