Choosing the right business structure is one of the most consequential decisions that a small business owner or freelancer can make. Whether you operate as a self-employed sole proprietor or form a limited liability company (LLC), your choice impacts virtually everything in your business, including:
How you pay taxes
Your personal liability protection
Ongoing administrative costs
Weighing the merits of operating as a sole proprietorship vs. an LLC is a little easier with this essential guide. Use it to understand the differences of each entity and for an outline of their pros and cons, so you can determine which path is the optimal fit for your business stage, risk profile, and financial goals.
Key Highlights
A sole proprietorship is the simplest way to operate, but it offers no personal liability protection.
An LLC provides a legal shield for your personal assets—if you follow compliance rules.
Both structures face self-employment tax obligations unless the LLC elects S corp status.
State filing fees and annual compliance costs vary widely, from $35 to $800+.
The optimal choice depends on your profit level, risk exposure, and client expectations.
S corp elections can save on self-employment taxes, but come with payroll and admin requirements that you can avoid with other entities.
Self-Employed vs. LLC – What’s the Difference?
Definitions (Legal vs. Tax Status)
When a freelancer, gig worker, or independent contractor says they're “self-employed,” they typically mean they operate as a sole proprietorship—an unincorporated business owned by one person, with no separate legal entity.
An LLC, on the other hand, is a legal business entity formed at the state level. By default, a single-member LLC is taxed like a sole proprietorship, while a multi-member LLC is taxed as a partnership. Both can elect corporate taxation, including S corp status, to harness potential tax benefits.
When Each Option Fits
Review each option, considering who benefits the most when operating as either business entity type.
Sole proprietorships are ideal for workers who wish to avoid extensive paperwork and formalities, including:
Low-risk freelancers
Solo consultants
Side hustlers
LLCs are common for growing businesses seeking credibility with clients and vendors, and who need to:
Sign contracts
Hire employees
Liability & Risk
Sole Proprietor Exposure
As a sole proprietor, you and your business are legally the same. This is great for workers who value simplicity, as long as they stay out of trouble. If your business is sued or owes money, your personal assets could be at risk, including your:
Bank account
Home
Vehicle
Business insurance can help, but it doesn't provide the complete personal liability protection enjoyed by LLCs and other business entities.
LLC Protections (and How to Keep Them)
Forming your business as an LLC creates a legal barrier between your personal and business assets, which is a popular feature. This protection is most effective if you:
Keep business and personal finances separate.
Maintain an operating agreement.
Use a registered agent.
Avoid “commingling” funds to reduce the risk of piercing the corporate veil.
Even with an LLC, insurance is still necessary. It adds an extra layer of protection that the legal structure alone can’t provide.
Taxes & Elections
Default Taxation & Self-Employment Tax
Both sole proprietors and single-member LLCs report business income on Schedule C (Form 1040), Profit or Loss from Business (Sole Proprietorship), and pay self-employment tax—15.3% of net earnings (12.4% Social Security up to the wage base, plus 2.9% Medicare). The 2025 Social Security wage base is $176,100.
Multi-member LLCs file IRS Form 1065, U.S. Return of Partnership Income, and issue a Schedule K-1 to each owner for reporting their share of income on their personal income tax returns.
LLC Taxed as S Corp (When It Helps)
An LLC can elect S corp status to potentially reduce self-employment tax. Owners must pay themselves a reasonable salary (subject to payroll taxes) and take remaining profits as distributions, which are not subject to self-employment tax.
This strategy can save money once your profits reach a steady mid-five-figure range or higher—but it adds payroll obligations and administrative work.
QBI Deduction Timing
Both sole proprietors and pass-through LLCs may qualify for the Qualified Business Income (QBI) deduction—up to 20% of qualified income. The deduction was set to expire after 2025, until it was made permanent via the Big Beautiful Bill, among other changes, business owners and self-employed individuals should know about.
Costs & Compliance
Formation & State Fees
LLC formation fees vary by state—from $35 to over $500, with a national average of around $132. Some states also charge annual franchise taxes, like California’s $800 minimum tax.
The time and paperwork can be overwhelming without 1-800Accountant's entity formation service, starting at $0 + state fees, working on your behalf.
Ongoing Admin
Both structures require basic bookkeeping and quarterly estimated tax calculations and submissions. While sole proprietors have fewer responsibilities, LLCs also face:
Annual state filings.
Registered agent fees.
Payroll filings, if taxed as an S corp.
Careful recordkeeping to maintain liability protection.
Decision Framework (Fast Yes/No Filters)
Profit, Risk, and Client Expectations
Review the following bullet points to help determine which scenario matches your business situation the closest. They will help you zero in on the optimal entity selection.
Low, unstable profits → Lean toward sole proprietorship.
Higher profits and steady income → Consider LLC, possibly with S corp election.
High liability industry or client contracts require LLC status → Form an LLC.
State Costs & Your Bandwidth
Forming as an LLC provides more protection, while operating as a sole proprietorship is simpler. When deciding the optimal entity type for your current operations, factor in your state’s formation and any annual fees, plus your willingness to handle the added paperwork—or work with a professional.
LLC vs. Self-Employed Scenarios
Consider the following LLC vs. self-employed scenarios to continue zeroing in on the optimal business structure.
Freelancer Netting ~$45k
Sole prop: Simpler, lower costs, but no liability shield.
LLC: Adds protection and credibility, but costs more annually without reducing self-employment tax.
Consultant Netting ~$120k+
LLC with S corp election: Reasonable salary of $70k, distributions of $50k could save thousands in self-employment taxes annually—but adds payroll duties and compliance costs that may distract from in-depth consultations.
Two-Owner E-Commerce
Multi-member LLC: Requires an operating agreement, issuing a Schedule K-1 to each member, and allocates profits per agreement. This is great for formalizing partnerships and managing buyout terms.
