Quick Summary
Your choice of business entity affects personal liability, taxes, fundraising ability, and administrative burden. The most common structures are LLC (flexible, liability protection), Corporation (investors, growth), Partnership (multiple owners, pass-through), and Sole Proprietorship (simple, single owner). Each has distinct advantages and trade-offs.
Business Entity Type Overview
A business entity type is the legal structure under which your business operates. This choice determines:
Liability Protection
Whether your personal assets (home, car, savings) are protected from business debts and lawsuits.
Taxation
How your business income is taxed (pass-through vs. corporate tax) and what deductions are available.
Ownership Structure
How many owners you can have, how ownership is transferred, and investor restrictions.
Compliance Requirements
Annual reports, meeting requirements, record-keeping obligations, and administrative burden.
Important: This Choice is Not Permanent
You can change your entity type later through conversion or restructuring. However, changing entities involves costs, paperwork, and potential tax implications—so it's best to choose wisely from the start.

Changing Entity Types
You can change your business entity type as your needs evolve. Common transitions include:
Sole Proprietorship → LLC
Most common transition. As your business grows and liability risk increases, converting to an LLC provides protection.
Process: Form new LLC, transfer assets, obtain new EIN, close sole proprietorship
LLC → S-Corporation (tax election)
When LLC profits exceed $60K-$80K, electing S-Corp taxation can reduce self-employment taxes.
Process: File Form 2553 with IRS. LLC remains LLC legally, only tax treatment changes.
LLC → C-Corporation
When seeking venture capital or preparing for IPO, converting to C-Corp becomes necessary.
Process: Statutory conversion or form new corp and merge LLC into it. Complex, requires legal assistance.
C-Corporation → S-Corporation
Small corporations may elect S-Corp status to avoid double taxation if they meet requirements.
Process: File Form 2553. Must meet S-Corp eligibility requirements (100 shareholders, etc.)
Important Considerations When Converting
- • Tax Implications: Conversions may trigger tax events—consult a tax professional
- • Costs: Filing fees, legal fees, accounting adjustments
- • Contracts: May need to update contracts and agreements
- • Bank Accounts: May need new EIN and updated bank accounts
- • Licenses: Business licenses may need to be updated or reissued
Frequently Asked Questions
Can one person own a corporation?
Yes. One person can be the sole shareholder, sole director, and hold all officer positions in a corporation. Many states allow single-person corporations.
What's the difference between an LLC and an S-Corp?
LLC is a business entity type; S-Corp is a tax classification. An LLC can elect to be taxed as an S-Corp. S-Corp taxation requires paying yourself a "reasonable salary" and can reduce self-employment taxes, but adds payroll complexity.
Do I need a lawyer to form an LLC or corporation?
Not required, but recommended for complex situations. Most people successfully form LLCs using online filing services ($0-$300) or doing it themselves. Corporations are more complex and may benefit from legal guidance, especially if you have multiple shareholders or complex ownership structures.
Can I operate in multiple states with one LLC?
Yes, but you'll need to register as a "foreign LLC" in each state where you conduct substantial business. This involves additional fees and annual reports in each state. Learn more about foreign qualification.
Which state should I form my business in?
Most small businesses should form in their home state where they physically operate. Delaware and Nevada are popular for corporations seeking VC funding or specific legal advantages, but for most LLCs and small businesses, your home state is best to avoid foreign registration fees.
How much does it cost to maintain an LLC vs Corporation?
LLC: $0-$800/year (state annual fees, registered agent). Corporation: $50-$800/year (annual reports) plus accounting/legal fees for corporate compliance (minutes, resolutions). Corporations typically cost 2-3x more annually to maintain.
