What Is a Sole Proprietorship? Pros, Cons & How It Works
Starting a business brings one immediate question: what legal structure should you choose? The options can feel overwhelming, especially when every article seems to assume you already know the basics. Let’s clear that up.
The short answer: If you’re testing a business idea, working alone, and earning less than $60,000 annually, a sole proprietorship works fine. If you want liability protection, plan to have partners, or need to reinvest profits back into growth, an LLC is usually better.
Quick Comparison: Sole Proprietorship vs LLC
| Factor | Sole Proprietorship | LLC |
|——–|——————-|—–|
| Formation | No paperwork needed | File articles of organization |
| Cost to Start | $0 | $50-$500 state filing fee |
| Liability Protection | None — you’re personally liable | Full protection of personal assets |
| Taxation | Pass-through (you pay personal rates) | Pass-through (but with more options) |
| Self-Employment Tax | 15.3% on all profits | 15.3% on all profits |
| Ownership | You only | Multiple owners allowed |
| Best For | Solo freelancers, side hustles | Most small businesses |
Sole Proprietorship Explained
A sole proprietorship isn’t actually a business entity at all. It’s just you, doing business under your own name (or a trade name you register). When you start freelancing, consulting, or selling products without forming an LLC or corporation, you’re automatically a sole proprietorship.
How Sole Proprietorship Taxation Works
This is refreshingly simple. All business income flows directly to your personal tax return on Schedule C. If your business makes $50,000 profit, you pay personal income tax rates on that $50,000.
You also pay self-employment tax of 15.3% on your entire profit. This covers Social Security and Medicare taxes that employees split with their employers. Since you’re both employer and employee, you pay both halves.
Real Pros and Cons
Pros:
- Zero startup costs or paperwork
- Complete control over decisions
- Simple tax filing (just add Schedule C to your 1040)
- Easy to dissolve — just stop doing business
Cons:
- You’re personally liable for all business debts and lawsuits
- No tax benefits for health insurance or retirement contributions
- Harder to get business loans or credit
- Dies with you — no business continuity
- Limited to one owner
Best for: Solo consultants, freelancers, photographers, tutors, and other service providers earning under $60,000 annually who work in low-risk industries.
LLC Explained
An LLC (Limited Liability Company) is a legal entity separate from you personally. You create it by filing Articles of Organization with your state and paying a filing fee.
How LLC Taxation Works
By default, LLCs use “pass-through” taxation just like sole proprietorships. Business profits flow through to your personal tax return, and you pay the same personal income tax rates and self-employment tax.
But LLCs have options sole proprietorships don’t. You can elect S-Corporation tax treatment to potentially save on self-employment taxes, or choose C-Corporation taxation if you want to reinvest profits in the business.
Real Pros and Cons
Pros:
- Personal asset protection from business liabilities
- More credible with customers, vendors, and lenders
- Can have multiple owners and different ownership percentages
- Flexible management structure
- Can elect different tax treatments as you grow
- Business continues if something happens to you
Cons:
- Costs $50-$500 to start (varies by state)
- Annual fees in most states ($50-$800)
- More paperwork and compliance requirements
- Need to maintain separation between personal and business finances
Best for: Most small businesses, especially those with liability risk, multiple owners, or annual profits over $60,000.
The Tax Difference — This Is the Big One
Let’s run the same business through both structures to see the real difference.
Example: You run a marketing consultancy that nets $80,000 annually.
As a Sole Proprietorship:
- Income tax on $80,000: ~$12,000 (assuming 15% effective rate)
- Self-employment tax: $80,000 × 15.3% = $12,240
- Total taxes: ~$24,240
As an LLC (default taxation):
- Income tax on $80,000: ~$12,000
- Self-employment tax: $80,000 × 15.3% = $12,240
- Total taxes: ~$24,240
Wait — they’re the same? Yes, by default. The LLC’s advantage isn’t tax savings; it’s liability protection and flexibility.
The S-Corp Election Strategy
Here’s where it gets interesting. LLCs can elect S-Corporation tax treatment, which can reduce self-employment taxes.
Same business as LLC electing S-Corp treatment:
- Pay yourself a “reasonable salary” of $50,000
- Remaining $30,000 is a distribution (not subject to self-employment tax)
- Self-employment tax: $50,000 × 15.3% = $7,650
- Savings: $4,590 annually
The catch? You need to run payroll, pay payroll taxes quarterly, and file additional forms. This typically costs $1,500-3,000 annually in accounting and payroll fees.
When S-Corp election makes sense: Generally when your LLC is netting over $60,000 annually and you can justify paying yourself a reasonable salary that’s less than total profits.
When to talk to a CPA: If your business nets over $50,000, you’re considering the S-Corp election, or you have complex deductions. Don’t wait until you’re making $200,000 to get tax help.
Ownership, Management & Raising Money
Sole Proprietorship Limitations
You can’t have partners or investors in a sole proprietorship. If you want to bring someone in, you’d need to either:
- Form a partnership (which has the same liability issues as sole proprietorships)
- Convert to an LLC or corporation
Selling the business is also complicated because you’re not selling a separate entity — you’re selling assets and transferring contracts.
LLC Flexibility
LLCs can have unlimited owners (called “members”) with different ownership percentages and rights. You can bring in investors, issue ownership interests, and structure different classes of membership.
Want to give your business partner 30% ownership but 50% of profits? LLCs allow this flexibility.
What investors expect: While LLCs work for small investments, venture capitalists and angel investors typically prefer C-Corporations. They want preferred stock, liquidation preferences, and other protections that LLCs don’t easily provide.
Which One Should You Pick?
Here’s our decision framework based on hundreds of formations we’ve processed:
Choose Sole Proprietorship if:
- You’re testing a business idea with minimal investment
- Working alone in a low-risk service business
- Earning under $30,000 annually
- Want the absolute simplest structure
Choose LLC if:
- You have any meaningful liability risk (selling products, having employees, client meetings at your location)
- Earning over $60,000 annually
- Plan to have partners or investors
- Want to appear more professional to customers and vendors
- Need to separate business and personal finances clearly
Industry-specific guidance:
- Freelance writers/designers: Sole proprietorship works until you’re earning $50K+
- E-commerce: LLC from day one due to product liability
- Restaurants/retail: LLC required due to customer liability
- Real estate: LLC for each property due to liability risk
- Software/apps: LLC if you plan to raise money, sole proprietorship for simple apps
Can You Switch Later?
Yes, and it’s common. Here are the typical conversion paths:
Sole Proprietorship to LLC
This is straightforward. Form the LLC, transfer assets and contracts to it, and start operating under the LLC. The IRS treats this as a non-taxable event if done properly.
Timeline: 2-4 weeks in most states.
LLC to Corporation
Also smooth. You can either:
- Convert the LLC to a corporation (if your state allows it)
- Form a new corporation and transfer LLC assets to it
When this makes sense: You’re raising venture capital, want to go public eventually, or need the structure of a corporation for tax planning.

For International Founders
If you’re not a U.S. resident but want to start a U.S. business, skip the sole proprietorship. Here’s why:
Tax complications: As a non-resident, sole proprietorship income creates complex U.S. tax filing requirements and potential double taxation issues.
Banking challenges: Most U.S. banks won’t open accounts for non-resident sole proprietorships.
Better option: Form an LLC or corporation. LLCs are particularly good for international founders because:
- Single-member LLCs can elect different tax treatments
- Banks will open accounts for LLCs more readily
- Clearer structure for international tax treaties
Common structure: International founders often form a U.S. LLC owned by their home country entity, which can provide better tax treatment under treaty provisions.
FAQ
Do I need an EIN for a sole proprietorship?
Not always. If you have no employees and use your Social Security Number for tax filing, you can skip the EIN. But most banks require an EIN to open business accounts, so you’ll likely need one anyway.
Can I hire employees as a sole proprietorship?
Yes, but you’ll need an EIN and must handle payroll taxes. Consider forming an LLC first — the liability protection is worth it once you have employees.
What’s a DBA and do I need one?
DBA means “doing business as.” If you operate under a name other than your legal name, most states require you to file a DBA. “John Smith Consulting” doesn’t need a DBA if John Smith owns it. “Acme Marketing Solutions” owned by John Smith does.
Can I write off business expenses as a sole proprietor?
Yes, same business deductions as any other business structure. Office supplies, equipment, business meals, travel — all deductible on Schedule C.
How do I pay myself from a sole proprietorship?
You don’t pay yourself a salary. All profits are automatically your income. Just transfer money from your business account to personal account as needed.
What happens to my sole proprietorship if I die?
It dies with you. Your heirs inherit the assets, but they’d need to start a new business entity to continue operations.
Can I have a business partner in a sole proprietorship?
No. By definition, sole proprietorships have one owner. Adding a partner automatically creates a partnership, which has different tax and legal requirements.
Should I get business insurance as a sole proprietor?
Yes. Professional liability insurance, general liability, or errors and omissions insurance can protect you from lawsuits that would otherwise target your personal assets directly.
Conclusion
Most people overthink business entity selection. If you’re working alone, testing an idea, and have minimal liability risk, starting as a sole proprietorship is fine. You can always convert to an LLC later when your income or risk profile changes.
But for most small businesses — especially those with growth plans, liability concerns, or earnings over $60,000 — an LLC provides better protection and flexibility for a modest cost.
