Ask HN: Should I incorporate as a freelancer?

I've been freelancing for a few weeks and I am wondering if it's worth it for me to become an Inc, LLC, Sole Proprietor, etc. The only business expenses I've had this year so far are moving and office space. I will be working out of Philadelphia and currently have clients in Boston and Vancouver, but that will likely change as I get more clients. Additionally, I foresee growth as I have been doing similar jobs for my clients and will likely continue to do these types of jobs.

Thank you!
