Why This Matters

Your business structure affects:

• Liability protection: Are your personal assets at risk?
• Taxes: How much will you pay?
• Growth: Can you raise capital easily?
• Complexity: How much paperwork and maintenance?

Choose wrong, and you pay the price:

• Unnecessary taxes
• Exposed personal assets
• Difficulty raising capital
• Expensive conversions later

Choose right, and you:

• Protect your assets
• Minimize taxes
• Position for growth
• Avoid costly mistakes

This decision tree helps you choose right the first time.

Quick Overview of Each Structure

Before we dive into the decision tree, here’s a quick overview of your three main options:

Sole Proprietorship

What it is: You and your business are the same legal entity. No separate formation required.

Pros:

• Simplest structure
• No formation fees
• Complete control
• Simple taxes

Cons:

• No liability protection (personal assets at risk)
• Hard to raise capital
• Limited growth potential
• Can’t sell the business easily

Best for: Very low-risk businesses with minimal liability exposure.

LLC (Limited Liability Company)

What it is: A separate legal entity that protects your personal assets while offering tax flexibility.

Pros:

• Liability protection
• Tax flexibility (pass-through or corporate taxation)
• Less paperwork than corporations
• Easy to form and maintain

Cons:

• Formation fees
• Some ongoing compliance
• Less attractive to some investors

Best for: Most small businesses and solo founders.

Corporation

What it is: A formal legal entity with shareholders, directors, and officers. Can be C-Corp or S-Corp for tax purposes.

Pros:

• Strong liability protection
• Easy to raise capital
• Can issue stock
• Attractive to investors

Cons:

• More complex and expensive
• More paperwork and compliance
• Double taxation (C-Corp) or restrictions (S-Corp)
• Requires formal governance

Best for: Businesses planning to raise significant capital or go public.

The 5-Question Decision Tree

Answer these 5 questions in order. Each answer leads you to the next question or to a recommendation.

Start here:

Question 1: Do You Need Liability Protection?

Ask yourself: If your business gets sued or can’t pay its debts, do you want your personal assets (home, car, savings) protected?

If YES → Go to Question 2

If NO → Consider Sole Proprietorship

When you might not need liability protection:

• Very low-risk business (writing, consulting with contracts, etc.)
• Minimal business assets
• Strong insurance coverage
• Comfortable with personal asset exposure

Warning: Most businesses benefit from liability protection. Even low-risk businesses can face unexpected lawsuits or debts.

Pro tip: If you’re unsure, choose liability protection. It’s better to have it and not need it than to need it and not have it.

Question 2: What Are Your Growth Plans?

Ask yourself: Do you plan to raise venture capital, go public, or attract institutional investors in the next 2-3 years?

If YES → Go to Question 5

If NO → Go to Question 3

Signs you might need a corporation:

• Planning to raise $1M+ in funding
• Want to go public (IPO)
• Need to attract venture capital firms
• Want to issue different classes of stock
• Planning to sell the company to a larger corporation

If you’re not sure: Most small businesses don’t need a corporation. Start with an LLC and convert later if needed.

Question 3: How Many Owners?

Ask yourself: How many people will own this business?

If 1 owner (just you) → Go to Question 4

If 2+ owners → LLC is likely your best choice

Why multiple owners favor LLC:

• LLCs are designed for multiple owners (members)
• Flexible ownership structure
• Easier to add or remove members
• Less formal governance requirements than corporations

Exception: If you answered YES to Question 2 (planning major growth/funding), you might still want a corporation even with multiple owners.

Question 4: Tax Complexity Tolerance

Ask yourself: How comfortable are you with tax complexity and ongoing compliance?

If you want SIMPLE taxes → LLC (default pass-through taxation)

If you’re comfortable with MORE complexity → Consider S-Corp election or Corporation

LLC tax simplicity:

• Profits and losses pass through to your personal tax return
• No separate business tax return (usually)
• Self-employment taxes on all profits
• Simple and straightforward

S-Corp election (LLC can elect this):

• Can reduce self-employment taxes by splitting salary and distributions
• More complex tax filing
• Requires payroll setup
• Worth it if you have significant profits ($50K+ annually)

Corporation taxes:

• C-Corp: Double taxation (corporate level + shareholder level)
• S-Corp: Pass-through but with restrictions
• More complex compliance

Pro tip: Most solo founders start with LLC default taxation. You can elect S-Corp status later if it makes sense.

Question 5: Future Funding Plans

Ask yourself: Do you need to raise significant capital from investors, venture capital firms, or through stock offerings?

If YES → Corporation (C-Corp) is likely best

If NO → Go back to Question 3

Why corporations for funding:

• Investors prefer corporations
• Easy to issue stock
• Can create different share classes
• Standard structure for venture capital
• Can go public (IPO) if needed

When LLC might still work:

• Raising from friends and family
• Small angel investments
• Don’t need institutional investors
• Can convert to corporation later

Pro tip: If you’re not sure about funding needs, start with LLC. You can convert to a corporation when you’re ready to raise significant capital.

Your Recommendation

Based on your answers, here’s what you should choose:

If you chose Sole Proprietorship:

You said: You don’t need liability protection and want the simplest structure.

Reality check: Make sure you’re comfortable with personal asset exposure. Consider business insurance. Be aware that you can’t easily sell or transfer the business.

When to reconsider: If your business grows, you add employees, or your liability risk increases, form an LLC.

If you chose LLC:

You said: You need liability protection, don’t need major funding immediately, and want tax simplicity.

This is the right choice for: Most solo founders and small businesses.

Next steps:

1. Form your LLC in your state
2. Get an EIN from the IRS
3. Create an operating agreement
4. Open a business bank account
5. Consider S-Corp election later if profits justify it

Resources:

• State-by-State Checklist

If you chose Corporation:

You said: You need liability protection, plan to raise significant capital, and are comfortable with complexity.

This is the right choice for: Businesses planning major growth, venture capital, or going public.

Next steps:

1. Form your corporation in your state (Delaware is popular for corporations)
2. Get an EIN from the IRS
3. Create bylaws and corporate records
4. Issue stock certificates
5. Set up corporate governance (board, officers)
6. Decide on C-Corp vs S-Corp tax status

Resources:

• LLC vs Corporation Comparison
• S-Corp vs C-Corp Guide

Pro tip: If you’re unsure between LLC and Corporation, start with LLC. It’s easier to convert to a corporation later than the reverse.

Next Steps

You’ve made your decision. Now what?

If You Chose Sole Proprietorship:

1. Get business insurance to protect against liability
2. Keep business and personal finances separate (use separate bank accounts)
3. Consider forming an LLC later if your business grows

If You Chose LLC:

1. Review our formation guide: Ultimate Guide to Forming an LLC
2. Check state requirements: State-by-State Checklist
3. Understand the paperwork: Formation Paperwork Guide
4. Avoid common mistakes: 21 Most Expensive Formation Mistakes

If You Chose Corporation:

1. Review entity comparisons: LLC vs Corporation
2. Understand tax options: S-Corp vs C-Corp
3. Consider professional help for corporate formation and governance
4. Plan your capital structure (types of stock, ownership percentages)

Still Unsure?

Common concerns:

“What if I change my mind later?”

• You can convert LLC to Corporation (or vice versa) later
• It’s easier to start simple (LLC) and convert to complex (Corporation) than the reverse
• Conversions have costs, so choose wisely, but don’t let perfect be the enemy of good

“What if my situation changes?”

• Business structures are flexible
• You can change your structure as your business evolves
• Many successful companies started as LLCs and converted to corporations when needed

“Should I consult a lawyer or accountant?”

• For simple situations (solo founder, straightforward business), you may not need professional help
• For complex situations (multiple owners, significant assets, tax planning), professional advice is valuable
• Use this decision tree first, then consult professionals if needed

Pro tip: Most solo founders with straightforward businesses are best served by an LLC. It offers liability protection without unnecessary complexity. You can always convert to a corporation later if your needs change.
