Deep Dive: Limited Liability Company (LLC)
How LLCs Work
An LLC is a hybrid entity combining the liability protection of a corporation with the tax benefits and flexibility of a partnership. Created by state statute, LLCs have become the most popular choice for new businesses, accounting for 70% of all new entity formations in 2024.
The LLC legally separates your personal assets from business liabilities, meaning creditors typically cannot pursue your home, car, or personal bank accounts for business debts. This “veil” of protection remains intact as long as you maintain proper separation between personal and business activities.
Tax Advantages of LLCs
Default Tax Treatment:
- Single-member LLC: Disregarded entity (taxed as sole proprietorship)
- Multi-member LLC: Partnership taxation
- No double taxation—profits pass through to owners
- Losses can offset other income (subject to rules)
Tax Flexibility: LLCs can elect different tax treatments:
- C-Corporation taxation (rare)
- S-Corporation taxation (common for profitable LLCs)
- Change election as business evolves
Example Tax Scenario: LLC with $200,000 profit, single member:
- As default LLC: $200,000 subject to self-employment tax (15.3%) plus income tax
- As S-Corp election: Salary $75,000 (payroll tax) + Distribution $125,000 (no SE tax)
- Potential savings: $19,125 annually
Management Flexibility
LLCs offer unmatched flexibility in structure:
Member-Managed:
- All owners participate in management
- Similar to partnership
- Best for small groups with active involvement
Manager-Managed:
- Designated managers run operations
- Members can be passive investors
- Better for larger groups or passive investors
Custom Operating Agreements:
- Allocate profits/losses disproportionately to ownership
- Create different classes of membership
- Specify voting rights and transfer restrictions
- Design succession planning
LLC Disadvantages
Limited Investment Options:
- Cannot issue stock
- Harder to grant equity to employees
- VCs typically won’t invest in LLCs
- Complicated to add many investors
State-Specific Issues:
- California: $800 minimum annual tax plus gross receipts fee
- New York: Publication requirement costing $1,000+
- Some states limit LLC lifespan
- Professional services restricted in some states
International Complications:
- Some countries don’t recognize LLCs
- Can create tax complications for foreign owners
- May be treated as corporation abroad
Deep Dive: C-Corporation
How C-Corporations Work
C-Corporations are separate legal entities owned by shareholders, managed by directors, and operated by officers. This formal structure has existed for centuries and remains the gold standard for larger businesses and those seeking institutional investment.
The corporation exists independently of its owners—it can enter contracts, sue and be sued, and continues existing even if ownership changes completely. This permanence and formal structure provide the strongest liability protection available.
The Double Taxation Issue
How Double Taxation Works:
- Corporation pays corporate tax on profits (21% federal)
- Shareholders pay tax on dividends received (up to 20% + 3.8% NIIT)
- Effective tax rate can exceed 40%
Example:
- Corporate profit: $100,000
- Corporate tax (21%): -$21,000
- After-tax profit: $79,000
- Dividend to owner: $79,000
- Personal tax (20%): -$15,800
- Net to owner: $63,200 (36.8% effective tax rate)
Strategies to Minimize Double Taxation:
- Pay salaries instead of dividends (deductible)
- Retain earnings for growth
- Provide employee benefits (deductible)
- Eventually sell stock for capital gains
Why Choose C-Corporation
Unlimited Growth Potential:
- No limit on number of shareholders
- Can have foreign investors
- Multiple classes of stock
- Easy to transfer ownership
Preferred by Investors:
- VCs almost exclusively invest in C-Corps
- Clean cap table management
- Standard investment documents

QSBS Tax Benefit: Hold stock 5+ years, exclude up to $10 million or 10x basis from federal capital gains tax—potentially saving millions on exit.
Employee Incentives:
- Issue stock options (ISOs and NSOs)
- Create employee stock purchase plans
- Restricted stock units (RSUs)
- Clear valuation for equity compensation
Corporate Formalities
Required Governance:
- Board of Directors (can be one person)
- Officers (President, Secretary, Treasurer)
- Annual shareholder meetings
- Board meetings and resolutions
- Written minutes for all meetings
Ongoing Compliance:
- Annual reports in all states
- Maintain corporate records book
- Issue stock certificates
- Keep stock transfer ledger
- More complex tax returns
Deep Dive: S-Corporation
Understanding S-Corp Election
An S-Corporation isn’t actually a business structure—it’s a tax election available to LLCs and Corporations that meet specific requirements. This election combines corporate formality with pass-through taxation, often providing the best of both worlds for profitable small businesses.
S-Corp Tax Benefits
The Self-Employment Tax Advantage: S-Corp owners who work in the business become employees, splitting income between:
- W-2 wages (subject to payroll tax)
- Distributions (not subject to SE tax)
Real-World Example: Business profit: $150,000
- As LLC: $150,000 × 15.3% = $22,950 SE tax
- As S-Corp: $60,000 salary × 15.3% = $9,180 payroll tax
- Savings: $13,770 annually
Reasonable Salary Requirement: IRS requires “reasonable compensation” for services. Factors include:
- Industry standards
- Experience and duties
- Time devoted
- Company revenues
- Regional wage data
S-Corp Restrictions
Ownership Limitations:
- Maximum 100 shareholders
- US citizens/residents only
- No corporate or partnership owners
- One class of stock only
- Cannot be owned by another LLC or Corporation
These Restrictions Prevent:
- Raising institutional capital
- Foreign investment
- Complex equity structures
- Going public
