Choosing S-Corp or LLC for your Business

Choosing the right legal structure for your business is a crucial decision that can have significant implications for taxation, liability, and overall operational flexibility. Two popular options for small businesses in the United States are the Limited Liability Company (LLC) and the S-Corporation (S-Corp). While both offer limited liability protection and flexibility, there are specific reasons why a business owner might opt for an S-Corp over an LLC. In this article, we’ll explore the advantages of selecting an S-Corp and why it might be the preferred choice for certain businesses.

What is an S-corp?

An S-Corp, short for Subchapter S Corporation, is a type of corporation that meets specific Internal Revenue Code requirements. The designation allows the corporation to pass income, losses, deductions, and credits directly to their shareholders for federal tax purposes. This means that the corporation itself does not pay income tax at the federal level. Instead, profits and losses are reported on the individual tax returns of the shareholders, and taxes are paid at the individual level. This structure avoids the double taxation commonly associated with traditional C Corporations, where both the corporation and the shareholders are taxed.

Key Features of an S-Corp:

  • Pass-through Taxation: Unlike C Corporations, which are subject to corporate income tax and then a second layer of tax on dividends paid to shareholders, S-Corps allow income to flow directly to shareholders to be taxed only once at their individual tax rates.
  • Limited Liability: Shareholders of an S-Corp enjoy limited liability protection, meaning their personal assets are protected from the corporation’s debts and liabilities.
  • Shareholder Restrictions: S-Corps face certain restrictions. They can have no more than 100 shareholders (with exceptions allowing for family members to be treated as a single shareholder), and shareholders must be U.S. citizens or resident aliens. Additionally, S-Corps can only have one class of stock, though differences in voting rights are permitted.
  • Salary and Dividend Payments: S-Corp shareholders who work for the company can be paid a salary and also receive additional distributions of profit, which are not subject to self-employment taxes. However, the IRS requires that the salary be “reasonable” for the work performed.
  • Election of S-Corp Status: To become an S-Corp, a corporation must first be formed as a general, for-profit corporation under the laws of the state in which it is incorporated. After formation, the corporation must elect S-Corp status by filing IRS Form 2553 no more than two months and 15 days after the beginning of the tax year the election is to take effect, or at any time during the tax year preceding the tax year it is to take effect.

Advantages of an S-Corp:

  • Tax Savings: The potential for significant tax savings, especially on self-employment taxes, is a key advantage.
  • Business Credibility: Incorporating can enhance a business’s credibility with potential customers, suppliers, and investors.
  • Estate Planning and Transferability: Shares of an S-Corp can be freely transferred without affecting the corporation’s continued existence or triggering adverse tax consequences, facilitating estate planning and ownership transfers.

Disadvantages of an S-Corp:

  • Regulatory Requirements and Costs: S-Corps face stricter regulatory requirements and costs than simpler structures like sole proprietorships and partnerships.
  • Shareholder Limitations: The limitations on the number and type of shareholders can restrict investment opportunities and capital raising.
  • Close IRS Scrutiny: The IRS pays close attention to S-Corps, particularly regarding salary distributions to shareholders, to ensure compliance with tax laws.

Choosing to operate as an S-Corp involves balancing the tax advantages and flexibility against the regulatory requirements and restrictions. For many small to medium-sized businesses, especially those that can benefit from pass-through taxation without incurring double taxation, the S-Corp offers a compelling structure.

Why would I choose S-corp entity classification?

Tax Advantages

  • Pass-through taxation: One of the primary reasons why business owners opt for an S-Corp is its pass-through taxation feature. Unlike a traditional corporation (C-Corp), where the business is taxed at the corporate level and then again at the individual level when dividends are distributed to shareholders, an S-Corp passes its income and losses through to its shareholders. This means that the business itself does not pay federal income taxes; instead, profits and losses are reported on the shareholders’ personal tax returns, avoiding double taxation.
  • Potential tax savings: Shareholders of an S-Corp can potentially save on self-employment taxes by classifying a portion of their income as distributions rather than salary. While shareholders who work for the company must receive reasonable compensation for their services, any remaining profits can be distributed as dividends, which are not subject to self-employment taxes.

Salary and Distributions

  • S-Corps provide more flexibility when it comes to distributing income to owners. While LLC members typically receive their share of profits directly, S-Corp shareholders have the option to take a reasonable salary as employees of the corporation. The remaining profits can be distributed as dividends, potentially resulting in lower overall employment tax obligations.

Limited Liability Protection

  • Like an LLC, an S-Corp offers limited liability protection to its shareholders. This means that the personal assets of shareholders are generally protected from business debts and liabilities, reducing the risk to individual owners.

Credibility and Perception

  • Some businesses, especially those seeking outside investment or aiming to establish credibility with clients or partners, may prefer the structure and formality associated with an S-Corp over an LLC. While both entities offer limited liability protection, an S-Corp may be perceived as a more established and structured business entity, which can be advantageous in certain industries or when dealing with sophisticated stakeholders.

Ease of Ownership Transfer

  • Transferring ownership interests in an S-Corp is often more straightforward compared to an LLC. S-Corps typically have a more rigid ownership structure with shares of stock that can be easily transferred or sold, making it easier to bring in new investors or transfer ownership to family members or other parties.

Requirements of S-corporations

S-Corporations have specific eligibility criteria and requirements they must adhere to, as dictated by the Internal Revenue Service (IRS). These requirements are intended to ensure that only certain types of corporations can benefit from the S-Corp taxation structure. The main requirements include:

1. Incorporation

Before a company can elect S-Corp status, it must first be incorporated by filing Articles of Incorporation with the relevant state authority and must comply with all the regulations that govern corporations in the state of incorporation.

2. IRS Election

To be considered an S-Corp, the corporation must file Form 2553, “Election by a Small Business Corporation,” with the IRS. This election must be made no more than two months and 15 days after the beginning of the tax year the election is to take effect, or at any time during the tax year preceding the tax year it is to take effect.

3. Domestic Corporation

The corporation must be a domestic corporation, meaning it is organized under the laws of a state or territory of the United States.

4. Eligible Shareholders

Shareholders must be individuals, certain trusts, and estates and cannot include partnerships, corporations, or non-resident alien shareholders. There is a limit of 100 shareholders for S-Corporations, although family members can elect to be treated as a single shareholder for this purpose.

5. One Class of Stock

Although an S-Corp can have different voting rights among shareholders, it can only have one class of stock. The IRS does not allow S-Corporations to have multiple classes of stock, which distinguishes it from C-Corporations that can issue different classes with varying rights and privileges.

6. Tax Year

Typically, an S-Corp must adopt a calendar year as its fiscal year unless it can establish a business purpose for a different fiscal year.

7. Compliance with State Laws

While the S-Corp election is a federal tax status, corporations must also ensure they comply with the state laws where they are incorporated and operate. Some states do not recognize the S-Corp election and will tax such entities as regular C-Corporations or have their own version of S-Corp election that must be filed.

8. Consent of Shareholders

All shareholders must agree to the corporation’s election of S status, even if they would not be affected by the election.

Maintaining S-Corp Status

After a corporation has successfully elected S-Corp status, it must continue to meet all eligibility requirements. Failure to do so can result in involuntary termination of the S-Corp status. For instance, if the corporation inadvertently accepts an ineligible shareholder or issues a second class of stock, it risks losing its S-Corp designation.

It’s essential for S-Corporations to maintain meticulous records and comply with all federal and state tax filing requirements, including the annual filing of Form 1120S, U.S. Income Tax Return for an S Corporation, and providing each shareholder with a Schedule K-1 showing their share of the corporation’s income, deductions, and credits.

Given the complexities and stringent requirements of maintaining S-Corp status, many businesses consult with legal and tax professionals to ensure ongoing compliance and to navigate the specific regulations that apply to their situation.

Example of tax savings of an s-corporation vs. LLC

To illustrate the potential tax savings of an S-Corporation (S-Corp) versus a Limited Liability Company (LLC), let’s consider a simplified example. Keep in mind that tax laws are complex and can change, and actual tax savings can vary based on numerous factors including the business’s income, the state in which it operates, and current tax rates. This example will focus on federal tax implications and the self-employment tax, which is a significant consideration for many small business owners.


  • Both S-Corps and LLCs offer pass-through taxation, meaning the income of the business is reported on the owners’ personal tax returns, and the business itself does not pay income tax.
  • The key difference comes in how salary and profit distributions are taxed, particularly concerning self-employment tax, which comprises Social Security and Medicare taxes. For 2023, the self-employment tax rate is 15.3% on the first $160,200 of combined wages, tips, and net earnings.

Example Scenario

Let’s assume you own a business that nets $100,000 in profit for the year. (Note: net profit is an important distinction. It is not gross income. Net profit is gross income less total expenses.) In this scenario, you’re deciding between operating as an LLC (taxed as a sole proprietorship or partnership) or an S-Corp.

As an LLC:

  • The entire $100,000 profit is subject to self-employment tax (15.3% up to the Social Security wage base, then 2.9% thereafter), in addition to income tax.
  • Self-Employment Tax: $15,300 (assuming all $100,000 is below the Social Security wage base).
  • Income Tax: This depends on your personal income tax bracket, but for simplicity, let’s say 22%.
  • Total Tax (excluding state taxes and assuming all income is below the Social Security wage base): $15,300 (self-employment) + $22,000 (income tax) = $37,300.

As an S-Corp:

  • You decide to pay yourself a reasonable salary of $40,000 for the work you do in the business, which is subject to Social Security and Medicare taxes (split between employer and employee, effectively the same rate as the self-employment tax for the LLC scenario but divided in half between employer and employee portions).
  • The remaining $60,000 is distributed as a dividend, which is not subject to self-employment tax.
  • Salary Tax: $6,120 (15.3% of $40,000).
  • The business also pays the employer portion of the FICA taxes, which is the same amount, $6,120, but this is a deductible business expense.
  • In effect, the Dividend Distribution (Not subject to self-employment tax) would be less than the $60,000 above due to the business paying the employer portion of the FICA taxes, lowering the taxable net profit of the business.
  • Income Tax: This applies to both the $40,000 salary and the business’s net profit. After adjusting the net profit with deductible salary and payroll tax expense, the total net profit of the business would be $56,940. Assuming the same 22% income tax rate, the total income tax is $12,527.
  • Total Tax (excluding state taxes): $6,120 (employee’s share of FICA on salary) + $12,527 (income tax on total $100,000) = $18,647.

Tax Savings Analysis

  • LLC Total Tax: $37,300
  • S-Corp Total Tax: $18,647
  • Savings with S-Corp: $18,653

This simplified example shows how an S-Corp can provide tax savings, primarily through the reduction of self-employment tax liability. The key factor here is the ability of S-Corp shareholders to split their income between a salary and profit distributions, with only the salary portion subject to employment taxes.

Important Considerations

  • Reasonable Salary: The IRS requires that S-Corp shareholder-employees be paid a reasonable salary for their role before taking profit distributions. What constitutes “reasonable” depends on industry standards, the business’s financial condition, and the duties performed.
  • Additional Costs and Complexity: Operating as an S-Corp may involve additional costs (e.g., payroll services, tax preparation fees) and regulatory requirements.
  • State Taxes: Some states do not recognize the S-Corp election or tax S-Corps differently, which can affect the overall tax benefits.

Consulting with a tax professional is crucial to analyze the specific circumstances of your business and to ensure compliance with all tax laws and regulations.

The bottom line

While both S-Corporations and LLCs offer limited liability protection and operational flexibility, there are specific advantages to choosing an S-Corp that may make it the preferred option for certain businesses. From tax advantages and limited liability protection to credibility and ease of ownership transfer, the decision to structure your business as an S-Corp should be based on careful consideration of your unique business needs, goals, and circumstances. Consulting with a qualified legal and tax advisor can help you weigh the pros and cons and make an informed decision that aligns with your business objectives.
