Hi @Wonnie - welcome to QB Community, and congratulations on your new gig! As an independent contractor I've never had to pay any additional taxes beyond the standard federal and state taxes. You can find some great tax resources and information on our Learning and Support page. (Definitely check out "Taxes for Freelancers.")

Moving forward, it's worth considering whether you should be paying estimated quarterly taxes rather than a lump sum come tax time. Here's a helpful primer on that.

What field are you in?
