What is the Main Difference Between S Corp and C Corp?

The main difference between S Corp and C Corp lies in their tax structures and eligibility requirements. An S Corp, also known as Subchapter S Corporation, is a special type of corporation created through an IRS tax election. It is designed for small businesses that prefer to pass corporate income, losses, credits, and deductions to their shareholders for federal tax purposes. By contrast, a C Corp, or C Corporation, is the standard corporation that is taxed separately from its owners and can have an unlimited number of shareholders, including international entities.

What is S Corp and What is C Corp?

S Corporation (S Corp):
An S Corp is a corporation that elects to be taxed under Subchapter S of Chapter 1 of the Internal Revenue Code. In most cases, S Corps are exempt from federal income tax other than tax on certain capital gains and passive income. Their profits and losses are passed through to shareholders and are taxed at individual income tax rates on their personal tax returns. This election offers the benefits of limited liability while avoiding the double taxation typically experienced by a C Corp. To qualify for S Corp status, a company must meet certain criteria, such as having fewer than 100 shareholders and only having individuals (and some trusts and estates) as shareholders, with no participation by non-resident aliens.

C Corporation (C Corp):
A C Corp is the most common type of corporation in the U.S. It is a legal entity that is separate from its owners, providing the benefit of limited liability, but is taxed separately from the owners at corporate income tax rates. Earnings of a C Corp can be reinvested in the company or paid out to shareholders as dividends, which are then taxed at the individual level, leading to what is known as “double taxation.” Since there is no limit to the number of shareholders a C Corp can have, they are often publicly traded companies and are subject to more regulations and corporate formalities than S Corps.

Key Differences Between S Corps and C Corps

  1. Taxation: S Corps are pass-through taxation entities, meaning income is reported on the shareholders’ personal tax returns. C Corps experience double taxation, with the corporation paying taxes at the corporate level, and shareholders paying taxes on dividends.
  2. Corporate Ownership: S Corps can have a maximum of 100 shareholders, who must be U.S. citizens or residents. C Corps can have an unlimited number of shareholders, including foreign individuals or entities.
  3. Stock Classes: S Corps are limited to one class of stock, which can restrict how ownership interests are structured. C Corps can issue multiple classes of stock, offering greater flexibility in ownership structure and capital raising.
  4. Formation and Formalities: S Corps must file an election with the IRS to obtain S Corporation status, which comes with stringent eligibility requirements. Meanwhile, C Corps do not have eligibility requirements beyond basic incorporations processes.
  5. Growth Potential: S Corps may be limited in their ability to grow due to the cap on the number of permissible shareholders and restrictions on who can be a shareholder. On the other hand, C Corps have the potential to grow significantly through additional investment from a wide array of shareholders.
  6. Regulatory Requirements: S Corps often have less rigorous filing and operational requirements than C Corps, which are typically larger companies with greater regulatory scrutiny.
  7. Investor Appeal: Investors may be more attracted to C Corps because of the potential for stock dividends, multiple stock classes, and opportunities for initial public offerings (IPOs).
  8. Employee Stock Compensation: C Corps have the flexibility to offer stock options or stock awards to employees, which is a valuable tool for attracting and retaining talent. S Corps are limited by their single class of stock and shareholder restrictions.

Key Similarities Between S Corps and C Corps

  1. Limited Liability Protection: Both S Corps and C Corps provide their shareholders with limited liability, meaning shareholders are typically not personally responsible for business debts and liabilities.
  2. Incorporation Process: The initial process of incorporating is similar for both S Corps and C Corps. Each must file articles of incorporation with their state, establish a board of directors, and follow internal and state-mandated corporate formalities.
  3. Structural Organization: Both entities are required to have a board of directors, officers, and to conduct annual meetings, along with keeping detailed meeting minutes to comply with state laws.
  4. Corporate Existence: S Corps and C Corps are both considered independent legal entities that can enter into contracts, own assets, sue or be sued, and have perpetual existence regardless of changes in ownership or management.
  5. Regulatory Compliance: Each must comply with federal and state regulations pertaining to corporations, including securities laws and corporate governance requirements.
  6. Operational Processes: Both are subject to certain operational similarities, like issuing stock to represent ownership and maintaining corporate records.

Advantages of S Corporation Status Compared to C Corporation

  1. Pass-Through Taxation: One significant advantage of an S Corp over a C Corp is the ability to pass corporate income, losses, credits, and deductions to their shareholders. This means that S Corp income is taxed only once at the shareholder level, avoiding the double taxation experienced by C Corps.
  2. Reduction in Taxable Gains: S Corps often face less tax burden when selling the business or its assets. This is because gains on such sales can pass through to shareholders, who may benefit from lower tax rates on capital gains compared to the corporate tax rates that would apply to a C Corp.
  3. Employment Tax Savings: Shareholders of an S Corp who work in the business can receive a portion of income as salary and the remainder as a distribution, which may result in reduced self-employment tax liabilities, as distributions are not subject to these taxes.
  4. Restriction on Ownership: While seen as a limitation, the restriction on having fewer than 100 shareholders and limits on who can be a shareholder help retain close control over the business, making it beneficial for small to medium-sized business owners who seek to avoid excessive outside influence.
  5. Ease of Ownership Transfer: Unlike C Corps, S Corps face no corporate level taxes on property transfers, which can make the transition of ownership simpler and more tax-efficient.
  6. Shareholder Requirements: Shareholders of S Corps must be U.S. citizens or residents, which can be beneficial for companies looking to maintain a domestic focus in their shareholder base.
  7. Accounting Simplicity: An S Corp’s pass-through taxation eliminates the need for complex corporate tax returns and helps simplify the accounting process, as corporate income and expenses are reported directly on the shareholders’ personal income tax returns.

Disadvantages of S Corporation Status Relative to C Corporation

  1. Restrictive Eligibility and Ownership Rules: Unlike C Corps, S Corps have strict criteria for eligibility, such as a limit of 100 shareholders and bans on non-individual entities as shareholders, which restricts investment opportunities and company growth.
  2. Stock Flexibility: S Corps are limited to issuing only one class of stock, restricting the company’s ability to raise capital through various types of equity offerings which could otherwise attract different levels of investors.
  3. Rigid Profit and Loss Allocation: Earnings and losses are allocated strictly according to each shareholder’s interest in the S Corp, which may not be desirable for certain investors who wish to structure preferential economic rights.
  4. Less Attractive to Foreign Investors: S Corps cannot have non-resident aliens as shareholders, making them less appealing to international investors, who may bring significant capital and growth opportunities.
  5. Increased IRS Scrutiny: Due to the benefits of pass-through taxation, S Corps may be more likely to face IRS audits, particularly concerning the categorization of payments to shareholders, such as salaries versus dividends.
  6. Lesser Appeal to Larger Investors: S Corps may not be as attractive to venture capitalists and institutional investors, who typically prefer the more flexible structure of a C Corp when investing substantial amounts of money.

Advantages of C Corporation Status Over S Corporation

  1. Unlimited Growth Potential: C Corps can have an infinite number of shareholders, which allows them to scale considerably by raising capital through the sale of stock to a diverse group of investors, including foreign individuals and corporations.
  2. Flexible Stock Options: C Corps are permitted to issue multiple classes of stocks with different voting and dividend rights, giving them the flexibility to attract a wide range of investors and raise funds for expansion or other business needs.
  3. International Investment Opportunities: C Corps can have foreign shareholders and can also invest in foreign companies, providing more opportunities for global expansion and diversification of the business.
  4. Attractiveness to Investors: Due to the ability to offer stock incentives and institutional investors’ familiarity with this corporate structure, C Corps are often more attractive to private equity firms and venture capitalists.
  5. Employee Incentives: C Corps have more flexibility in providing stock options or other equity-based compensation to employees, which can be a powerful tool for recruiting and retaining top talent.
  6. Public Company Potential: C Corps are equipped to go public through an IPO, offering opportunities for significant capital acquisition and heightened public profile, which is not possible for S Corps due to their ownership restrictions.

Disadvantages of C Corporation Status Relative to S Corporation

  1. Double Taxation: One primary disadvantage of C Corps is double taxation. Corporate income is taxed at both the corporate level and again at the individual level when dividends are paid to shareholders.
  2. Complexity in Tax Reporting: C Corps face more complex tax reporting requirements and regulations. The necessity to file separate corporate tax returns adds to the administrative burden and may lead to higher accounting fees.
  3. Regulatory Scrutiny: As larger entities that often engage in a wider scope of business activities, C Corps are subject to more rigorous regulatory scrutiny and compliance requirements, increasing overhead and reducing operational flexibility.
  4. Inflexibility in Profit Sharing: Unlike S Corps, where profits and losses can pass through to shareholders, C Corps lack flexibility in profit distribution and must adhere to formal dividend procedures.
  5. Restricted Ability to Deduct Losses: In contrast to S Corps, where shareholders can deduct losses on their personal tax returns, C Corp losses are retained within the corporation, which may not be advantageous for businesses experiencing initial losses.
  6. Challenges in Ownership Transfers: Transfer of ownership in a C Corp might invoke various tax consequences since changes in stock ownership can lead to taxable events.

When S Corporation Status is Preferable Over C Corporation

  1. Limited Shareholders: Small businesses with fewer than 100 shareholders can find an S Corp status more suitable, especially if the goal is to keep the business closely held and maintain tighter control over company decisions.
  2. Pass-Through Taxation: Businesses looking to avoid the double taxation characteristic of C Corps would benefit from the S Corp structure, where company profits are only taxed once, through the shareholder’s personal income tax.
  3. Simplified Tax Reporting: Owners who prefer a more straightforward approach to tax reporting would benefit from an S Corp. Since profits and losses are reported on personal tax returns, there’s no need to file a separate corporate tax return.
  4. Estate and Gift Taxes: An S Corp can be beneficial when planning for estate and gift taxes. Owners can gift shares without triggering corporate tax events, allowing for easier wealth transfer to family members.
  5. Asset Protection: Those seeking to protect their personal assets from business liabilities would find the S Corp favorable, as it provides a shield for personal assets against debts or legal claims against the business, similar to a C Corp.
  6. Self-Employment Tax Savings: Business owners who want to minimize self-employment taxes might find an S Corp advantageous since earnings can be split into salary and dividends, potentially reducing the amount subject to such taxes.
  7. Attracting Domestic Investors: If a company’s focus is on attracting investors who are U.S. residents or citizens, S Corp status can be beneficial due to its restrictions on foreign investment.

When C Corporation Status is Preferable Over S Corporation

  1. Growth and Funding: Companies with ambitions to grow rapidly, particularly through public offerings or a diverse shareholder base, may find C Corp status more beneficial due to its ability to issue various classes of stock and have an unlimited number of shareholders.
  2. Attracting International Investors: Firms looking to attract international capital or planning to operate on a global scale would benefit from a C Corp’s ability to include foreign individuals and corporations as shareholders.
  3. Employee Stock Plans: Organizations that want to use stock options or other forms of employee equity participation as a tool to recruit and retain employees will appreciate the flexibility provided by C Corps.
  4. Estate Planning: Larger companies that require more sophisticated estate planning mechanisms may prefer the C Corp structure, which allows for more complex transitions and ownership structures.
  5. Venture Capital: Startups seeking significant venture capital funding might opt for a C Corp since many investors prefer or require this structure due to its flexibility in equity and potential for IPO.
  6. Flexibility in Profit Distributions: C Corps have advantages in managing and allocating profits, providing flexibility on when and how earnings are distributed, as well as the option to retain profits within the company for growth.
  7. Maintaining Profits within the Company: Businesses that intend to reinvest profits back into the company, rather than distributing them, may prefer C Corp status as this can facilitate tax-deferred growth.

Comparative Features of S Corporations and C Corporations

  1. Tax Structure: S Corps offer pass-through taxation where the income flows directly to the shareholders’ personal tax returns, while C Corps are taxed at the corporate level and also upon dividend distributions.
  2. Shareholder Limitations: S Corps have a cap of 100 shareholders, all of whom must be U.S. residents or citizens, whereas C Corps can have unlimited shareholders with no citizenship requirements.
  3. Investment Flexibility: C Corps provide a higher degree of flexibility in raising capital through different types of stock offerings, while S Corps are limited to one class of stock and cannot attract certain types of investors.
  4. Operational Requirements: Both S Corps and C Corps must adhere to corporate formalities, such as holding regular board meetings and keeping accurate minutes, but C Corps may face more stringent regulatory and reporting requirements.
  5. Growth Potential: C Corps often have greater potential for growth through public offerings and large-scale investment opportunities, whereas S Corps are more constrained by the types of investors and the number of shareholders they can have.
  6. Employee Incentives: While C Corps have the advantage of offering various types of stock-based compensation to employees, S Corps are limited due to their single class of stock and tighter shareholder rules.
  7. International Activities: C Corps have the ability to engage in international business and have non-U.S. shareholders, which may be critical for businesses looking to expand beyond national borders.

Evaluating the Right Entity for Tax Purposes

Choosing the right corporate structure is pivotal for managing a company’s tax liabilities and overall financial strategy.

Analyzing the Impact on Financial Statements

Selecting between an S Corp and C Corp affects how business activities are reported on financial statements. With an S Corp, shareholders must incorporate their share of profits and losses into their personal income statements, which could complicate their personal finances, particularly if the corporation operates at a loss or has a complex financial structure. Conversely, C Corps report their own income and expenses independently, resulting in a standalone corporate tax return. This separation can streamline personal financial reporting for individual owners but may lead to increased scrutiny on the corporate accounts, as corporate financial statements are often subject to rigorous financial analysis by investors, lenders, and regulatory bodies.

Considering State-Level Tax Implications

It’s important to note that the choice between an S Corp and C Corp doesn’t just have federal tax implications. Often overlooked are the state-level tax regulations that may favor one type of corporation over another. Some states do not recognize the S Corp election and will tax these businesses as C Corps, negating the federal tax benefits of pass-through taxation at the state level. Additionally, state corporate income tax rates and regulations vary widely, which can also heavily influence the decision. Businesses must consult with tax professionals to fully grasp the potential tax implications at the state level and make an informed choice based on where the company operates.

Strategic Considerations Beyond Taxation

It is essential to consider the broader strategic implications of choosing between an S Corp and a C Corp, as these decisions extend beyond tax considerations.

Long-Term Business Vision and Corporate Goals

A business’s long-term vision should significantly influence its choice between an S Corp or C Corp. An S Corp may be the suitable choice for businesses that aim to stay relatively small and closely held, as it can provide tax benefits and ease of ownership transfer that are conducive to closely-knit operations. On the other hand, a C Corp might be the right choice for businesses that aspire to grow large, potentially go public, or attract a wide circle of investors. The potential to issue various classes of stock and to retain earnings within the corporation for reinvestment purposes aligns well with expansive corporate aspirations.

Flexibility for Future Business Changes and Adaptation

Future business changes, such as mergers, acquisitions, or changes in ownership, may be more smoothly facilitated under the C Corp structure due to its greater flexibility in terms of ownership and stock classification. A C Corp can also adapt more readily to shifts in investor base and capital structure, which is advantageous in the dynamic corporate landscape. Conversely, an S Corp might face certain limitational hurdles due to stricter shareholder and stock classifications that could inhibit swift adaptation to changing business environments. Thus, a business that envisions frequent restructuring or reorganization might be better served as a C Corp.

Corporate Image and Public Perception

The corporate structure a business chooses can also influence its image and public perception. A C Corp, particularly when public, has a perception of stability and prominence that could be valuable in building credibility with customers, suppliers, and investors. An S Corp, with its more intimate ownership structure, may not evoke the same perception but may appeal more to niche markets or local communities that value small, personal businesses. Therefore, how a company wishes to be viewed by the public and its stakeholders might influence whether an S Corp or C Corp is more appropriate.


What criteria must a business meet to qualify for S Corp status?

To qualify as an S Corp, there are specific criteria that a business must meet. These include having no more than 100 shareholders, ensuring all shareholders are U.S. citizens or residents, and maintaining only one class of stock. Moreover, all shareholders must be individuals or certain types of trusts and estates, with partnerships, corporations, and non-resident alien shareholders being excluded.

Can an S Corp have non-U.S. citizens as shareholders?

No, one of the requirements of an S Corp is that all shareholders must be U.S. citizens or residents. The structure does not allow non-resident aliens to own stock, which limits the potential for international investment in comparison to a C Corp.

How does the pass-through taxation of S Corps affect individual shareholders?

Pass-through taxation means the profits and losses of an S Corp are reported on the personal tax returns of the shareholders. Individual shareholders will pay income tax at their personal tax rates on their share of the corporation’s income, avoiding the double taxation which C Corps face where income is taxed at both the corporate and individual shareholder levels.

What are the state-level considerations when choosing between an S Corp and a C Corp?

When evaluating the choice between an S Corp and a C Corp, considering state-level tax implications is also important since some states do not recognize the S Corp election and will tax these entities similar to C Corps. State corporate income tax rates and regulations can vary, potentially impacting the decision. Consulting with a tax professional is recommended to understand the detailed implications in the company’s operating state(s).

How does the single class of stock affect an S Corp’s ability to raise capital?

The requirement for an S Corp to have only a single class of stock limits the company’s ability to raise capital, as it cannot issue preferred or other variations of stock that might appeal to a broader range of investors. In contrast, C Corps can issue multiple classes of stock with different rights and privileges, appealing to a more diverse group of investors.

Is it possible for an S Corp to convert to a C Corp?

Yes, an S Corp can convert to a C Corp by revoking its S Corp election with the IRS. However, it is important to note that specific tax consequences and regulations must be adhered to during the process. Professional tax advice is recommended to navigate the change effectively.

Do C Corps face more regulatory scrutiny compared to S Corps?

C Corps often face greater regulatory scrutiny compared to S Corps due to their potentially larger size, wider scope of activities, and requirements if public. This increased oversight can lead to more complex compliance and reporting obligations.

How do employee stock benefits differ between S and C Corps?

C Corps have more flexibility in offering stock options and other forms of equity compensation to employees, which can be a significant advantage for attracting and retaining talent. On the other hand, an S Corp is limited by its single class of stock and restrictive shareholder requirements, which may not offer the same level of incentive to employees.

Are S Corps or C Corps better for businesses planning substantial growth?

For businesses projecting substantial growth, a C Corp may be better suited as it allows for an unlimited number of shareholders, does not restrict shareholder residency, and can issue multiple classes of stock. This flexibility accommodates greater investment and opportunities, like IPOs, which may not be possible or as effective for an S Corp.

How do ownership transfer rules vary between S Corps and C Corps?

Ownership transfers in S Corps can be simpler and more tax-efficient, with no corporate level taxes on property transfers. Conversely, C Corps may incur various tax consequences during ownership changes, with stock transfers potentially triggering taxable events, adding complexity to the transfer process.

S Corp vs C Corp Summary

While both S Corps and C Corps provide limited liability protection and have the potential for perpetuity, they present different advantages and challenges that cater to varying business needs. An S Corp is best suited for smaller businesses seeking to benefit from pass-through taxation and simplicity in tax reporting but must abide by strict shareholder regulations. Meanwhile, a C Corp is fit for larger-scale operations aiming for significant growth potential through the flexibility of stock issuance and foreign investment capabilities, albeit at the cost of dealing with double taxation and comprehensive regulatory requirements. Careful evaluation of both structural forms in context of strategic goals and tax positions can help business owners align with the model that best suits their company’s future.
