Don't start a business if it's just you: there is no reason and it can sharpley curb your potential client list.

Freelancers are just freelancers and pay taxes as such. A business is usually set up to limit the financial liability that can be held against you in the event that you mess up really badly.

It doesn't save you any money and you can still write off the expenses as business expenses as a freelancer.

I started a company with some other people and we started a s-corporation. all sorts of paperwork (i didn't have to do it, that was the business department's work) that took up a ton of time.
