What is an S Corporation?
An S Corporation, commonly known as an “S Corp,” is a tax classification granted by the Internal Revenue Service (IRS) that allows a corporation or Limited Liability Company (LLC) to pass corporate income, losses, deductions, and credits directly to shareholders for federal tax purposes. This means the business itself generally pays no federal income tax, and taxes are instead paid at the individual owner level based on their share of the income.
How Does an S Corporation Work?
Unlike a standalone business entity such as a sole proprietorship, partnership, or corporation, the S Corp status is a tax election available to domestic corporations and certain LLCs that meet specific IRS criteria. To elect S Corp status, a business must file IRS Form 2553 within a designated time frame, typically by March 15 for calendar-year filers, to be taxed as an S Corporation for that tax year.
A hallmark of the S Corp is “pass-through” taxation. Unlike C Corporations, which face double taxation—once at the corporate level and again when dividends are paid to shareholders—an S Corporation’s profits and losses are passed directly onto its shareholders’ personal tax returns. Shareholders then pay income tax at their individual rates, avoiding the corporate tax layer.
Owners employed by the S Corp must pay themselves a “reasonable salary” subject to employment taxes (Social Security and Medicare). Profits remaining after paying the reasonable salary can be distributed as dividends, which are generally not subject to self-employment taxes. This structure can result in tax savings compared to sole proprietorships and partnerships where all income may be subject to self-employment tax.
Eligibility Requirements for S Corporation Status
The IRS imposes several requirements for a business to elect S Corp status:
- Domestic Corporation: The business must be a U.S.-based corporation or an eligible LLC.
- Eligible Shareholders: Shareholders must be individuals (U.S. citizens or residents), certain trusts, or estates. Partnerships, corporations, and non-resident aliens are generally disqualified.
- Shareholder Limit: A maximum of 100 shareholders is permitted.
- Single Class of Stock: Only one class of stock is allowed, meaning all shares confer identical rights to distributions and liquidation proceeds.
- Eligible Business: Certain financial institutions, insurance companies, and some other types of businesses are ineligible.
Advantages of Operating as an S Corporation
- Pass-Through Taxation: Avoids double taxation by reporting income and losses on individual tax returns.
- Self-Employment Tax Savings: Only reasonable salaries are subject to employment taxes; additional distributions typically are not.
- Limited Liability Protection: Provides corporate liability protections for its owners.
- Potential to Raise Capital: Though limited to 100 shareholders, S Corps can issue stock to raise funds.
Common Scenarios for S Corporation Use
Freelancers and Small Business Owners: Those with profitable businesses who want to reduce self-employment tax burdens often benefit from S Corp status.
LLCs Seeking Tax Benefits: LLCs frequently elect S Corp status to enjoy pass-through taxation alongside self-employment tax advantages.
Closely Held C Corporations: Businesses wanting to avoid double taxation on profits, especially those not seeking many investors, may convert to S Corp status.
Important Compliance Matters and Tips
- Reasonable Salary: IRS guidelines require owners to pay themselves a reasonable salary, comparable to industry standards. Underpaying can trigger audits and penalties.
- Maintain Formalities: S Corps must observe corporate formalities such as holding annual meetings, maintaining minutes, and keeping business accounts separate from personal finances to preserve liability protection.
- Timely Tax Filings: S Corps must file Form 1120-S annually by March 15 (or the 15th day of the third month after the fiscal year ends) and provide Schedule K-1s to shareholders.
- State Tax Considerations: Some states do not recognize S Corp status, potentially imposing state corporate taxes regardless of federal treatment.
- Professional Advice: Consult a qualified tax professional to determine if S Corp status is beneficial and ensure regulatory compliance.
Common Misconceptions
- Not a Business Entity Type: The S Corp status is a tax classification, not a legal business entity. Businesses must first form a corporation or eligible LLC.
- All LLCs Are Not S Corps: An LLC can be taxed as a sole proprietorship, partnership, C Corp, or S Corp depending on elections made with the IRS.
- Not All Income is Tax-Free: Although distributions avoid self-employment taxes, salaries remain subject to payroll taxes.
- Proper Record-Keeping Is Crucial: Detailed documentation of salaries, distributions, and corporate activities is required to maintain S Corp status and avoid IRS scrutiny.
Real-World Examples
Consider Sarah, a freelance web designer. As a sole proprietor, she pays self-employment taxes on all her earnings. By forming an LLC and electing S Corp status, Sarah pays herself a reasonable salary subject to employment taxes, but can distribute remaining profits without self-employment tax, saving thousands annually.
Similarly, Mark owns a boutique originally structured as a C Corporation. Facing double taxation on profits, he converts to an S Corporation to streamline taxation and retain more earnings for growth.
