One of the biggest misconceptions about LLCs is that they save you money on taxes. The truth is more nuanced: a single-member LLC is taxed exactly the same as a sole proprietorship by default. However, an LLC can elect S-Corp taxation, which can save significant money. Understanding the tax differences between LLC and sole proprietorship is critical for making the right business structure decision. This comprehensive guide explains everything you need to know about LLC vs. sole proprietor taxes in 2026.

The Tax Reality: They're the Same (By Default)
This is the most important point:
Single-Member LLC = Sole Proprietor (Tax-Wise)
Key fact: A single-member LLC is taxed exactly the same as a sole proprietorship by default.
Tax filing: Schedule C (same form) Self-employment tax: 15.3% on all profit (same rate) Income tax: Based on tax brackets (same brackets) Deductions: Same deductions available
There is NO tax difference between a single-member LLC and a sole proprietorship by default.
Why People Think LLCs Save Taxes
Common misconception: "LLCs save you money on taxes"
Reality: LLCs provide liability protection, not tax benefits (by default)
The confusion: People hear about S-Corp tax savings and assume all LLCs get that benefit, but S-Corp is an election you must make (and it's available to LLCs, not sole proprietorships)
The S-Corp Difference
Sole proprietorship: Cannot elect S-Corp taxation (must form LLC or corporation first)
LLC: Can elect S-Corp taxation (this is where tax savings come from)
Key point: The tax savings come from S-Corp election, not from being an LLC itself.
Sole Proprietor Tax Structure
Here's how sole proprietors are taxed:
Tax Filing
Form: Schedule C (Profit or Loss from Business)
What you report:
- Gross income (all client payments)
- Business expenses (deductible expenses)
- Net profit (income - expenses)
Where it goes: Schedule C attaches to your personal tax return (Form 1040)
Self-Employment Tax
Rate: 15.3% of net profit
Breakdown:
- 12.4% Social Security (on first $168,600 in 2026)
- 2.9% Medicare (on all income)
- Additional 0.9% Medicare on income above $200,000 (single) or $250,000 (married)
Calculation: Net profit × 92.35% × 15.3% = Self-employment tax
Example: $50,000 net profit
- Tax base: $50,000 × 92.35% = $46,175
- Self-employment tax: $46,175 × 15.3% = $7,065
Income Tax
Rate: Based on tax brackets (10%-37%)
Calculation: (Net profit - Standard deduction) × Tax bracket = Income tax
Example: $50,000 net profit, single filer
- Standard deduction: $14,600
- Taxable income: $35,400
- Income tax: ~$4,000
Total Tax
Example: $50,000 net profit
- Self-employment tax: $7,065
- Income tax: $4,000
- Total: $11,065 (22.1% of net profit)
LLC Tax Structure (Default)
Here's how a single-member LLC is taxed by default:
Tax Filing
Form: Schedule C (Profit or Loss from Business) - Same as sole proprietorship
What you report:
- Gross income (all client payments)
- Business expenses (deductible expenses)
- Net profit (income - expenses)
Where it goes: Schedule C attaches to your personal tax return (Form 1040) - Same as sole proprietorship
Self-Employment Tax
Rate: 15.3% of net profit - Same as sole proprietorship
Calculation: Net profit × 92.35% × 15.3% = Self-employment tax - Same as sole proprietorship
Example: $50,000 net profit
- Tax base: $50,000 × 92.35% = $46,175
- Self-employment tax: $46,175 × 15.3% = $7,065 - Same as sole proprietorship
Income Tax
Rate: Based on tax brackets (10%-37%) - Same as sole proprietorship
Calculation: (Net profit - Standard deduction) × Tax bracket = Income tax - Same as sole proprietorship
Example: $50,000 net profit, single filer
- Standard deduction: $14,600
- Taxable income: $35,400
- Income tax: ~$4,000 - Same as sole proprietorship
Total Tax
Example: $50,000 net profit
- Self-employment tax: $7,065
- Income tax: $4,000
- Total: $11,065 (22.1% of net profit) - Same as sole proprietorship
Key Point
There is NO tax difference between a single-member LLC (default) and a sole proprietorship. They're taxed identically.
LLC with S-Corp Election
This is where tax savings come from:
What Is S-Corp Election?
How it works: LLC elects to be taxed as S-Corporation
Tax filing: More complex (Form 1120-S, payroll, etc.)
Key difference: Must pay yourself "reasonable compensation" (salary), then can take distributions
Self-Employment Tax (S-Corp)
How it works:
- Salary: Subject to FICA (7.65% employee portion) - not full 15.3%
- Distributions: Not subject to self-employment tax (only income tax)
Example: $100,000 profit
- Salary: $60,000 (reasonable compensation)
- FICA on salary: $60,000 × 7.65% = $4,590
- Distributions: $40,000 (no self-employment tax)
- Total self-employment tax: $4,590 (vs. $15,300 as sole proprietor)
Savings: $10,710 (but must pay payroll, more complex)
Income Tax (S-Corp)
How it works:
- Income tax on salary + distributions (same brackets)
- No difference in income tax (just how it's structured)
Example: $100,000 profit
- Salary: $60,000
- Distributions: $40,000
- Total taxable: $100,000 (same as sole proprietor)
- Income tax: ~$15,000 (same as sole proprietor)
Total Tax (S-Corp)
Example: $100,000 profit
- FICA on salary: $4,590
- Income tax: ~$15,000
- Total: ~$19,590
Sole proprietor comparison: ~$30,300 Savings: ~$10,710 (but must pay reasonable salary, more complex filing)
The "Reasonable Compensation" Requirement
IRS requirement: Must pay yourself "reasonable compensation" (salary)
What's reasonable:
- Based on what similar employees make
- Usually 40-60% of profit for most freelancers
- IRS can challenge if too low
Example: $100,000 profit
- Reasonable salary: $50,000-$70,000 (typical range)
- Can't pay yourself $10,000 and take $90,000 as distribution (IRS will challenge)
Tax Comparison: Real Examples
Let's compare real scenarios:
Example 1: $50,000 Profit
Sole Proprietor:
- Self-employment tax: $7,065
- Income tax: $4,000
- Total: $11,065
LLC (Default):
- Self-employment tax: $7,065
- Income tax: $4,000
- Total: $11,065 (same as sole proprietor)
LLC (S-Corp Election):
- Salary: $30,000 (reasonable)
- FICA: $2,295
- Distributions: $20,000
- Income tax: $4,000 (same)
- Total: $6,295
Savings: $4,770 (but must pay payroll, more complex - may not be worth it at this income level)
Example 2: $100,000 Profit
Sole Proprietor:
- Self-employment tax: $14,130
- Income tax: $15,000
- Total: $29,130
LLC (Default):
- Self-employment tax: $14,130
- Income tax: $15,000
- Total: $29,130 (same as sole proprietor)
LLC (S-Corp Election):
- Salary: $60,000 (reasonable)
- FICA: $4,590
- Distributions: $40,000
- Income tax: $15,000 (same)
- Total: $19,590
Savings: $9,540 (likely worth it at this income level)
Example 3: $150,000 Profit
Sole Proprietor:
- Self-employment tax: $20,906 (Social Security capped at $168,600)
- Income tax: $28,000
- Total: $48,906
LLC (Default):
- Self-employment tax: $20,906
- Income tax: $28,000
- Total: $48,906 (same as sole proprietor)
LLC (S-Corp Election):
- Salary: $75,000 (reasonable)
- FICA: $5,738
- Distributions: $75,000
- Income tax: $28,000 (same)
- Total: $33,738
Savings: $15,168 (definitely worth it at this income level)

When Each Structure Makes Sense
Here's when to choose each:
Choose Sole Proprietorship If:
✅ You're just starting out (income is low, uncertain) ✅ Your income is under $75,000 (S-Corp may not be worth complexity) ✅ You want simplicity (no formation costs, simple tax filing) ✅ You don't have significant assets to protect ✅ You have low liability risk
Tax benefit: None (but no costs, simple)
Choose LLC (Default) If:
✅ You want liability protection (have assets to protect) ✅ Your income is under $75,000 (S-Corp not worth it yet) ✅ You want professional appearance ✅ You're willing to pay formation/ongoing costs ✅ You may want S-Corp later (easier to elect from LLC)
Tax benefit: None (same as sole proprietor), but liability protection
Choose LLC (S-Corp) If:
✅ Your income is $75,000+ (S-Corp savings justify complexity) ✅ You're willing to handle payroll and more complex filing ✅ You want to maximize tax savings ✅ You have significant income (savings are substantial)
Tax benefit: Can save $5,000-$15,000+ in self-employment tax (depending on income)
Costs vs. Tax Savings
Understanding the math:
Sole Proprietorship Costs
Formation: $0 Ongoing: $0 Tax preparation: Simple (Schedule C) Total: $0
LLC (Default) Costs
Formation: $50-$500 Ongoing: $0-$800/year Tax preparation: Same as sole proprietor (Schedule C) Total: $50-$1,300 first year, $0-$800/year ongoing
Tax savings: $0 (same taxes as sole proprietor)
Net benefit: Liability protection only (no tax benefit)
LLC (S-Corp) Costs
Formation: $50-$500 Ongoing: $0-$800/year Payroll: $500-$2,000/year (if using service) Tax preparation: $500-$1,500 more (more complex) Total: $1,050-$4,800 first year, $1,000-$3,300/year ongoing
Tax savings: $5,000-$15,000+ (depending on income)
Net benefit: Tax savings minus costs (usually positive if income is high enough)
Break-Even Analysis
S-Corp usually makes sense if:
- Income is $75,000+ (savings are $5,000+)
- Costs are $2,000-$3,000/year
- Net savings: $2,000-$12,000+/year
At $50,000 income: Savings may be $4,000, but costs are $2,000-$3,000, net savings only $1,000-$2,000 (may not be worth complexity)
At $100,000+ income: Savings are $9,000+, costs are $2,000-$3,000, net savings $6,000-$7,000+ (definitely worth it)
How to Elect S-Corp Taxation
Here's the process:
Step 1: Form LLC (If Not Already)
Must have LLC first (or corporation) - sole proprietorships cannot elect S-Corp
Step 2: Get EIN
Get Employer Identification Number from IRS (free, online)
Step 3: File Form 2553
File Form 2553 (Election by a Small Business Corporation) with IRS
Deadline: Within 2 months and 15 days of formation, or by March 15 of tax year
Important: Must file on time (late election may be denied)
Step 4: Set Up Payroll
Must pay yourself salary (reasonable compensation)
Options:
- Use payroll service ($20-$50/month)
- Do it yourself (more complex)
- Hire accountant (more expensive)
Step 5: File S-Corp Tax Return
File Form 1120-S (S Corporation Income Tax Return)
More complex than Schedule C - consider hiring accountant
Step 6: Maintain Separation
Must maintain:
- Business bank account
- Payroll records
- Separation of salary and distributions
Frequently Asked Questions
Do LLCs Pay Less Taxes Than Sole Proprietorships?
By default, no. Single-member LLC is taxed same as sole proprietorship. But LLC can elect S-Corp (can save on self-employment tax if income is high enough).
Can a Sole Proprietorship Elect S-Corp?
No. Must form LLC or corporation first, then elect S-Corp.
How Much Can S-Corp Save Me?
Depends on income. Usually $5,000-$15,000+ per year if income is $75,000+. But must pay reasonable salary and handle more complexity.
Is S-Corp Worth the Complexity?
Usually yes, if income is $75,000+. Savings usually justify costs and complexity. Below $75,000, may not be worth it.
Can I Switch from Sole Proprietor to LLC Later?
Yes. You can form LLC anytime. Your tax ID may change (EIN vs. SSN), but you can transition.
Can I Switch from LLC Default to S-Corp Later?
Yes. You can elect S-Corp anytime (file Form 2553). But must file on time (within 2 months 15 days of formation, or by March 15).
What If I Don't Pay Myself Reasonable Salary?
IRS can challenge. They can reclassify distributions as salary, making you pay back taxes and penalties. Must pay reasonable salary.
Bottom Line: Which Should You Choose?
The answer depends on your situation:
Choose Sole Proprietorship If:
✅ Just starting out ✅ Income under $50,000 ✅ Want simplicity ✅ Don't have assets to protect ✅ Low liability risk
Tax: Same as LLC default (no difference)
Choose LLC (Default) If:
✅ Want liability protection ✅ Income $50,000-$75,000 ✅ Willing to pay formation costs ✅ May want S-Corp later
Tax: Same as sole proprietor (no tax benefit, but liability protection)
Choose LLC (S-Corp) If:
✅ Income $75,000+ ✅ Willing to handle complexity ✅ Want to maximize tax savings ✅ Have significant income
Tax: Can save $5,000-$15,000+ in self-employment tax
General Rule
For taxes alone:
- Sole proprietor = LLC default (no difference)
- LLC S-Corp can save money (if income is high enough)
For liability protection:
- LLC (default or S-Corp) provides protection
- Sole proprietor has no protection
Most freelancers: Start as sole proprietor, form LLC when income/assets grow, elect S-Corp when income is $75,000+
Final Thought
The tax difference between LLC and sole proprietorship is often misunderstood. By default, they're taxed the same. The tax savings come from S-Corp election (which requires LLC or corporation). Don't form an LLC expecting tax savings—form it for liability protection, and consider S-Corp election when your income is high enough to justify the complexity.
