Before you hire employees, raise money, or sign contracts, you need a legal entity. The structure you choose affects your taxes, personal liability, ability to raise money, and administrative burden. Getting this right matters, and changing later is complicated.
Why Entity Structure Matters
•
Business debts are your debts
•
Lawsuits can hit your savings
Proper structure creates separation.
•
Different reporting requirements
•
Different planning opportunities
Structure affects how much you pay.
•
Clean corporate governance
Wrong structure blocks investment.
Match complexity to your needs.
Simplest form—just you, operating.
•
Simple taxes (personal return)
Best for: Side projects, testing ideas before formalizing.
Two or more people, not incorporated.
•
Partners personally liable
•
Can’t easily add investors
•
Partner departures complicated
Best for: Small professional practices.
LLC (Limited Liability Company)
Flexible entity with liability protection.
•
Pass-through taxation (usually)
•
Less formality than corporation
•
Not ideal for VC fundraising
•
Harder to issue equity compensation
•
Self-employment taxes for some members
Best for: Lifestyle businesses, consulting, real estate, certain partnerships.
Standard corporate structure.
•
Double taxation (corporate + dividends)
Best for: Companies planning to raise VC or issue stock options.
Corporation with pass-through taxation.
•
Avoids self-employment tax on distributions
Best for: Small businesses that want corporate structure with pass-through taxation.
Corporation with social mission.
•
Benefit corporation status
•
Same basic structure as C Corp
•
Additional reporting requirements
Best for: Mission-driven companies where social benefit is core.
Most startups incorporate in Delaware:
Even if you operate in California:
•
Register as foreign corporation in your state
•
Pay taxes where you operate
•
Delaware just for legal structure
Consider your own state if:
•
Never planning to raise VC
•
Don’t want foreign registration overhead
Choice: Delaware C Corporation
Investors expect it. Stock options work cleanly. Standard structure.
Choice: LLC (in your state)
Pass-through taxation. Less formality. Adequate protection.
Tax efficiency. Flexibility. Appropriate liability protection.
Choice: Start LLC, convert later
LLCs can convert to C Corps if you later want to raise.

DIY vs. Service vs. Lawyer
DIY: Possible but risky. Easy to miss things.
Services (Stripe Atlas, Clerky): Good for standard formations. Affordable.
Lawyer: Best for complex situations. More expensive.
For standard VC-track startup, services work well.
•
Operating agreement amendments as needed
•
Annual reports (some states)
Commingling funds:
Mix personal and business money → lose liability protection.
Not documenting:
No minutes, no resolutions → corporate veil problems.
Ignoring foreign registration:
Operating without registering → fines and penalties.
Maintaining Corporate Veil
Keep business and personal separate:
•
Corporate formalities observed
Commingling can “pierce the veil” exposing personal assets.
•
Legal documents for conversion
•
Issuing significant stock options
Converting after complexity (many members, investors) is harder.
•
Dividends taxed again to shareholders
•
But: can retain earnings, reinvest
•
Qualified Small Business Stock (QSBS) exclusion possible
•
Owners report on personal returns
•
Can be advantageous for profitable businesses
If profitable and not raising VC:
•
Pass-through often better
•
Depends on your situation
If raising VC or not immediately profitable:
•
C Corp double taxation less impactful
•
QSBS benefits significant
Consult a tax advisor for your specific situation.
•
Entity structure affects liability, taxes, fundraising, and complexity

Maintain corporate formalities to preserve liability protection
•
LLCs can convert to C Corps later if needed
•
Tax implications depend on your profitability and fundraising plans
