Quick Answer

Tax differences: Identical for most freelancers
Here's what surprises most people: single-member LLCs and sole proprietorships are taxed exactly the same way. Both are "pass-through" entities where business income flows directly to your personal tax return.
Both structures use:
Tax filing example for $60,000 freelance income:
The IRS treats single-member LLCs as "disregarded entities" — meaning they're ignored for tax purposes unless you make a special election.
Liability protection: The biggest difference
This is where the structures diverge significantly:
Sole Proprietorship liability:
Single-Member LLC liability:
Real-world example: If a client sues you for $100,000 over a project dispute:

When to choose sole proprietorship
Best for:
Example scenario: Sarah is a new freelance writer expecting to earn $15,000 in her first year. A sole proprietorship keeps things simple while she builds her client base.
When to choose single-member LLC
Best for:
Example scenario: Mike is a freelance web developer earning $75,000 annually with a mortgage and retirement savings. The LLC's liability protection justifies the $400 annual cost.
Making the switch
You can start as a sole proprietor and convert to an LLC later without tax penalties. Many freelancers make this switch when they:
What you should do
Evaluate your situation using these criteria:
1. Annual income: Under $30K = consider sole proprietorship; Over $30K = lean toward LLC
2. Risk level: Low-risk services can stay sole proprietorship; Higher-risk work benefits from LLC protection
3. Personal assets: More assets = more reason for LLC protection
4. Client types: Corporate clients often prefer LLCs

Key takeaway: Single-member LLCs and sole proprietorships have identical taxes but different liability protection. Choose sole proprietorship for simplicity under $30K income, or LLC for asset protection and business credibility above $30K.
