Many people start side hustles without formally creating a business entity. Selling products online, freelancing, driving for delivery apps, creating content on YouTube, offering consulting services, photography, social media management, and countless other side businesses often begin as simple one-person operations.
One of the most common questions new entrepreneurs ask is whether they should remain a sole proprietor or form an LLC. Both options can work for side hustles, but they differ in areas like liability protection, privacy, taxes, costs, and long-term business structure.

This guide explains the differences between an LLC and a sole proprietorship and helps side hustle owners decide which option may make the most sense for their situation.
What Is a Sole Proprietorship?
A sole proprietorship is the default business structure for a one-person business. In most cases, if you start earning money from a business activity without formally creating an LLC or corporation, you are automatically operating as a sole proprietor.
There is usually no separate legal filing required to become a sole proprietor.
Examples of side hustles commonly operated as sole proprietorships include:
- Freelance writing
- Graphic design
- Photography
- Rideshare driving
- Food delivery
- Online reselling
- Social media consulting
- Lawn care services
- YouTube channels
- Affiliate marketing
The business and the owner are legally considered the same entity.
What Is an LLC?
An LLC, or Limited Liability Company, is a separate legal business entity formed through state registration.
Unlike a sole proprietorship, an LLC creates legal separation between the business and the owner in many situations.
An LLC may help:
- Separate business liabilities from personal assets
- Create a more professional business structure
- Simplify partnerships
- Build business credibility
- Provide branding advantages
- Allow additional tax flexibility
Many entrepreneurs eventually transition from a sole proprietorship to an LLC as their side hustle grows.
Key Differences Between an LLC and Sole Proprietorship
Liability Protection
One of the biggest differences involves liability protection.
Sole Proprietorship
With a sole proprietorship, the owner is personally responsible for business debts and liabilities.
If the business is sued or cannot pay debts, personal assets could potentially be exposed.
LLC
An LLC may help create separation between personal assets and business liabilities when operated properly.
This is one of the main reasons many side hustle owners eventually form LLCs.
However, LLC protection is not absolute, and business owners still need:
- Proper insurance
- Separate business finances
- Good bookkeeping
- Legal compliance
Startup Costs
Sole Proprietorship
A sole proprietorship is usually the cheapest and simplest option because there may be little or no state filing cost.
Some businesses may still need:
- Local business licenses
- DBA registrations
- Tax permits
LLC
LLCs typically require:
- State filing fees
- Annual report fees in some states
- Registered agent requirements
- Ongoing compliance maintenance
Depending on the state, LLC formation costs can range from under $50 to several hundred dollars.
Taxes
Sole Proprietorship Taxes
Sole proprietors typically report business income directly on their personal tax return using Schedule C.
Business profits are generally subject to:
- Income tax
- Self-employment tax
LLC Taxes
A single-member LLC is often taxed similarly to a sole proprietorship by default.
However, LLCs may offer additional tax flexibility later, including potential S corporation tax elections for qualifying businesses.
Many side hustle owners begin as sole proprietors and later form LLCs once income increases.
Privacy Considerations
Sole Proprietorship
Sole proprietors often operate directly under their personal identity unless they file a DBA (“Doing Business As”).
LLC
LLCs may provide more business separation and branding opportunities.
However, LLC formation records are often public, and state filing information may become searchable online.
Some entrepreneurs use professional registered agent services to help improve privacy.
Popular registered agent providers include:
Professional Appearance
An LLC may create a more established business image.
Many customers, vendors, and lenders view LLCs as more formal businesses compared to sole proprietorships.
This may help with:
- Client trust
- Business banking
- Vendor relationships
- Commercial leases
- Business credit applications
For some side hustles, professionalism may become increasingly important as revenue grows.
Business Banking
Sole Proprietorship
Some banks allow sole proprietors to open business accounts using:
- Social Security Number
- DBA filing
- EIN
LLC
LLCs typically open business accounts using:
- Articles of Organization
- EIN
- Operating agreement in some cases
Keeping business finances separate is important regardless of structure.
When a Sole Proprietorship May Make Sense
A sole proprietorship may work well if:
- The side hustle is very small
- Startup costs need to stay minimal
- Liability risk is low
- The business is experimental
- Income is inconsistent
- You are testing a business idea
Many entrepreneurs initially start as sole proprietors before deciding whether the business justifies forming an LLC.
When an LLC May Make Sense
An LLC may become attractive if:
- The business is earning steady income
- Liability concerns increase
- Clients expect professionalism
- The business signs contracts
- You hire contractors or employees
- You want stronger business separation
- You own rental property
- You operate an online brand
Many growing side hustles eventually transition into LLCs as the business becomes more serious.
Common Side Hustles That Often Use LLCs
Certain side hustles frequently evolve into LLCs over time.
Examples include:
- Real estate investing
- YouTube channels
- Affiliate marketing businesses
- Ecommerce stores
- Consulting businesses
- Photography businesses
- Coaching businesses
- Marketing agencies
- Web design businesses
- Amazon sellers
As income and exposure increase, many entrepreneurs become more interested in liability protection and formal business structure.
Can You Start as a Sole Proprietor and Later Form an LLC?
Yes. Many entrepreneurs begin as sole proprietors and later convert to an LLC.
This is extremely common.
Business owners often wait until:
- Revenue increases
- Risks become larger
- Business operations become more complex
- They want stronger branding
- They need liability separation
Transitioning later may allow entrepreneurs to avoid unnecessary costs while testing business ideas.

Final Thoughts
For many side hustles, starting as a sole proprietor is the fastest and cheapest way to begin earning income. However, as the business grows, many entrepreneurs eventually decide that the additional structure and potential liability separation of an LLC are worth the extra cost and paperwork.
The right choice depends on factors such as:
- Business risk
- Income level
- Long-term goals
- Privacy concerns
- Industry type
- Client expectations
Some entrepreneurs never need an LLC, while others benefit from forming one early in the business journey. Understanding the differences between an LLC and a sole proprietorship can help side hustle owners choose the structure that best fits their current situation and future plans.
