S corp vs. C corp: Key differences and benefits
Presented by Chase for Business.
Quick insights
- S corporations and C corporations are two common business ownership structures that allow for company shareholders.
- Both offer liability protection for owners but differ in tax treatment, ownership limitations and administrative obligations.
- Choosing between an S Corp and a C Corp may depend on factors such as tax preferences, capital raising objectives and ownership structure.
Choosing the right business structure can directly impact your tax liabilities, ability to raise capital and long-term growth. In addition to Limited Liability Companies (LLCs), S corporations and C corporations are common options in the small business world.
Whether you are a solo consultant looking to optimize your take-home pay, a tech founder preparing for venture capital or a scaling retailer eyeing international expansion, understanding the strategic differences between S corps and C corps can be highly beneficial. This guide covers the key features of S corps and C corps, compares their benefits and explains how to form the entity that best aligns with your business goals.
What is an S corp?
An S corporation is a corporate status that allows income, losses, deductions and credits to pass through directly to shareholders for federal tax purposes. This setup can help business owners avoid double taxation that is typical of traditional corporations.
S corps are required to meet specific eligibility criteria and can have no more than 100 shareholders. All shareholders are required to be U.S. citizens or residents and only one class of stock is allowed. These restrictions preserve a S corp’s tax-advantaged status but may limit flexibility if you plan to bring on institutional investors later.
S corp taxation
Income in an S corp is taxed only at the shareholder level, meaning the company generally does not pay federal corporate income tax. This pass-through taxation may be beneficial for small to medium-sized service businesses looking to reduce their overall tax burden and effectively manage self-employment taxes.
What is a C corp?
A C corporation is a conventional corporation considered a separate legal entity from its owners. It can have unlimited shareholders (including foreign investors) and issue multiple classes of stock. This structure is often popular with high-growth startups and larger companies aiming to raise significant capital.
C corps also can offer broad access to capital markets. For example, if you are building a tech platform, a C corp allows you to issue preferred stock to angel investors while reserving common stock for early employees.
C corp taxation
Unlike an S corp, a C corp pays corporate income tax on its profits. When dividends are distributed, you and your shareholders are taxed again on those payments, resulting in double taxation.
How are an S corp and C corps similar?
S corps and C corps share several foundational traits that make both viable business entities. A few of their similarities include:
- Legal separation: Both are legally separate from their owners, offering liability protection that can protect your personal assets from business debts and lawsuits.
- Incorporation: Both require formal state incorporation, including filing articles of incorporation and adhering to corporate formalities such as board meetings and record maintenance (similar to how incorporated companies differ from LLCs).
- Capital: Both structures allow you to raise capital by issuing stock.
- Ownership transfer: S corps and C corps provide business continuity, allowing for the potential transfer of ownership without dissolving the company.
Key differences between an S corp and C corp
While sharing some features, S corps and C corps differ in key areas that may be critical to how you operate your business and plan for growth:
Taxation
C corps pay corporate income tax on profits, and shareholders are taxed again on dividends. S corps can avoid this double taxation by passing income directly to shareholders, who report it on their personal returns.
How to choose: If avoiding double taxation is a top priority and your business qualifies, an S corp may help reduce your overall tax liability. However, if you intend to aggressively reinvest profits into inventory or marketing rather than taking large distributions, the C corp tax structure might work to your advantage.
Ownership restrictions
S Corps limit businesses to 100 shareholders, require all owners to be U.S. citizens or residents and permit only one stock class. C Corps have no such limits and can issue multiple classes of stock to accommodate different types of investors.
How to choose: An S corp restricts you to no more than 100 shareholders, and all owners are required to be U.S. citizens or residents. If you anticipate having a large number of shareholders or plan to partner with international investors, a C corp can provide more structural flexibility.
Raising capital
C corps can be attractive to venture capitalists because of their more flexible ownership rules, whereas those with an S corp may find raising institutional capital more difficult due to stricter ownership limits.
How to choose: If your roadmap includes seeking venture capital or partnering with overseas manufacturers who want equity, a C corp may be necessary. If you start as an S corp to enjoy early tax benefits, be aware that converting to a C corp later is possible but requires careful legal and financial planning.
Administrative requirements
C corps often face more complex reporting demands than S corps because a C corp can accommodate unlimited shareholders and multiple stock classes. S corps generally offer simpler tax procedures but may require vigilant monitoring to help prevent accidentally violating eligibility standards, such as going over the 100-shareholder limit.
How to choose: A C corp often involves more complex regulatory reporting and detailed equity tracking. An S corp generally offers simpler tax filings but requires vigilant monitoring to help ensure you do not accidentally violate strict eligibility rules. Additionally, as an S corp owner, the IRS requires you to pay yourself a "reasonable salary," which can affect your payroll taxes. C corps also pay salaries, but dividends may be taxed separately.
