Sole Proprietorship vs. LLC in the USA: Which Structure Fits Your Small Business?

When you start earning regular money from a side business or freelance service in the United States, choosing the right legal structure protects your personal finances. The two most common starting options are a Sole Proprietorship and a Limited Liability Company (LLC).

A Sole Proprietorship requires no formal state filing to begin—you simply operate under your own name and report business profits on Schedule C of your personal tax return. However, it offers no separation between personal and business liability. An LLC, on the other hand, creates a separate legal entity that protects your personal assets (like your home or personal savings) if your business faces a lawsuit or debt. For low-risk solo gig work, starting as a Sole Proprietor is simple, while forming an LLC makes sense once your revenue and client risk grow.
