What is an LLC?
LLC stands for Limited Liability Company. It’s a popular business structure that combines the simplicity of a sole proprietorship with the liability protection of a corporation.
Key features of an LLC:
- Owners are called members
- Can have one or multiple members
- Offers pass-through taxation
- Protects personal assets from business liabilities
- Fewer formalities than corporations
Why choose an LLC?
An LLC is ideal for entrepreneurs and freelancers who want a flexible business model with limited legal risk and minimal regulatory paperwork.
What is an S-Corp?
An S-Corp (short for Subchapter S Corporation) is not a business entity type but a tax classification. You can elect S-Corp status by filing Form 2553 with the IRS after forming a corporation or LLC.
Key features of an S-Corp:
- Must meet IRS eligibility criteria
- Allows pass-through taxation like an LLC
- Avoids double taxation
- Owners must be U.S. citizens or residents
- Limited to 100 shareholders
Why choose an S-Corp?
An S-Corp is perfect for small business owners who want to reduce self-employment taxes and plan to take part of their earnings as a salary and the rest as dividends.
Key Differences Between LLC and S-Corp
| Feature | LLC | S-Corp |
|---|---|---|
| Formation | State-level registration | IRS election after LLC/Corp formation |
| Ownership | Unlimited members | Max 100 shareholders, only U.S. citizens |
| Management | Member-managed or manager-managed | Board of directors and officers |
| Taxation | Pass-through by default | Pass-through, salary + distribution |
| Self-Employment Tax | Applied on full income | Only on salary portion |
| Profit Distribution | Flexible | Must be based on ownership |
| Paperwork | Minimal | Requires more formal compliance |
Pros and Cons of LLCs
✅ Pros of LLCs:
- Simple to set up and maintain
- Flexible profit distribution
- No limit on the number of owners
- Personal liability protection
- Pass-through taxation avoids double tax
❌ Cons of LLCs:
- Full income subject to self-employment tax
- May have limited growth potential
- Fewer tax-saving opportunities for high-income businesses
Pros and Cons of S-Corps
✅ Pros of S-Corps:
- Avoids double taxation
- Lower self-employment tax
- Credibility with investors and lenders
- Allows reasonable salary and dividends strategy
- Better for high-profit businesses
❌ Cons of S-Corps:
- Must pay owner a “reasonable salary”
- Stricter eligibility requirements
- More administrative tasks and IRS scrutiny
- Limits on ownership and shareholder types
Tax Differences: LLC vs S-Corp
One of the biggest deciding factors between an LLC and an S-Corp is how the business is taxed.
📌 LLC Taxes:
- Default tax treatment: Pass-through
- Single-member LLCs are taxed like sole proprietorships
- Multi-member LLCs are taxed like partnerships
- Owners pay self-employment tax (15.3%) on all net income
- Can elect to be taxed as an S-Corp for savings
📌 S-Corp Taxes:
- Income is split into salary and dividends
- Only salary is subject to self-employment tax
- Dividends are taxed at a lower rate
- Requires reasonable salary per IRS guidelines
- Must file payroll taxes and Form 1120-S
Example:
If your business earns $100,000:
- As an LLC, the entire $100K is subject to self-employment tax.
- As an S-Corp, if you pay yourself a $60K salary and $40K dividend, only $60K is taxed for Social Security/Medicare.
Compliance Requirements
LLC Compliance:
- Annual state filing (varies by state)
- Operating agreement (not always required)
- No mandatory annual meetings
S-Corp Compliance:
- File IRS Form 2553 to elect S-Corp status
- File annual reports and meeting minutes
- Maintain proper payroll documentation
- More detailed IRS reporting
