Sole Proprietorship vs LLC:
Do You Actually Need One?
The honest answer most sites will not give you. Math-first, independent, not written by anyone selling LLC formation.
Stay a Sole Proprietor If...
- + Your revenue is under $30k per year
- + You do low-liability work (writing, design, consulting)
- + You have no employees and no plans to hire
- + Your clients do not require an LLC
- + You want zero setup cost and minimum paperwork
Form an LLC If...
- + Your revenue exceeds $50k and you want S-Corp tax savings
- + Your work has real liability risk (physical, products, advice)
- + You are hiring or plan to hire employees
- + A client contract or grant requires it
- + You want to bring on a partner or raise capital
"You do not need an LLC to be a legitimate business. Millions of sole proprietors run profitable companies without one."
The Thing Vendors Will Not Tell You
Most articles about this topic are written by LegalZoom, ZenBusiness, Northwest Registered Agent, and similar companies. They earn $20 to $75 every time someone forms an LLC through their platform. This creates an obvious bias toward "you should form an LLC." We earn nothing from recommending sole proprietorship, and our affiliate links (on the Formation Services page only) are disclosed prominently. Our honest advice: if you make under $30k from a side hustle, the LLC costs more than it saves.
