C corporations (C corps) remain one of the most common corporate structures in the United States. In September 2023 alone, the US Census Bureau reported nearly 473,000 new business applications. Out of the 32,000 or so that will result in fully formed corporate entities, many will become C corps. Although the motivation for forming a C corp is clear – to take advantage of opportunities for growth and set the business up for success – the process of forming a C corp is more opaque.

Below, we'll unpack the key steps involved in forming a C corp. If you're considering this corporate structure, here's what you need to know about its attributes and benefits, and how to make it the legal framework for your business.

What is a C corp?

A C corp is a type of business entity, formed under US state law, that establishes the business as distinct from its owners or shareholders. As a C corp, the business earns money and pays taxes at corporate rates, while the shareholders are only liable for paying taxes on their investment, which shields them from direct corporation liabilities.

Key attributes of a C corp

As with other corporate structures, C corps are defined by their unique attributes and implications for businesses, which are important to understand as you evaluate whether a C corp offers you the best fit. Here is what a C corp structure means for businesses:

  • Separate legal entity: a C corp operates as an independent entity, distinct from its owners or shareholders.

  • Limited liability: shareholders' financial responsibility is limited to their investment, which protects personal assets against business debts.

  • Double taxation: the corporation pays taxes on its profits. When these profits are distributed as dividends, shareholders pay taxes on their personal returns.

  • Shareholder structure: a C corp can have an unlimited number of shareholders and shares can be traded publicly.

  • Perpetual existence: the corporation continues to exist even if the owners or shareholders change or die.

  • Management structure: shareholders elect a board of directors, who in turn appoint officers to manage daily operations.

Benefits of forming a C corp

Choosing a corporate entity is a one of the decisions that can have the most impact on a business, because the structure has a direct influence on growth potential, tax implications and stakeholder relationships. The C corp is a popular choice for businesses in a range of industries, particularly those that hope to scale or seek external investment. Here are some of the perks that come with choosing to incorporate as a C corp:

  • Limited liability protection: shareholders have a protective barrier between their personal assets and business debts. This protection can offer peace of mind in the event of legal action or if the business faces financial challenges.

  • Growth potential through stock issuance: C corps can issue different classes of stock, which allows them to raise capital from investors. This is particularly attractive to venture capitalists and private equity investors.

  • No shareholder restrictions: unlike other business entities, C corps don't have restrictions on the number of shareholders that they can have. This feature can be significant for companies that are considering going public.

  • Attracting talent with stock options: offering stock options or shares can be a compelling incentive to attract and retain top-tier talent, especially for sectors in which competition for skilled professionals is high.

  • Perpetual existence: a C corp maintains its business continuity regardless of shareholder changes, which can be advantageous for long-term planning.

  • Tax flexibility with retained earnings: although double taxation is often considered to be a drawback, C corps can choose to retain earnings and reinvest in the business, which can sometimes lead to a lower effective tax rate.

C corps offer an appealing combination of financial flexibility, growth opportunities and a shield against certain risks. For businesses considering significant expansion or those seeking to make themselves as attractive as possible to investors, the C corp is a compelling choice. Once you've identified a C corp as the most advantageous option for your business, based on your goals and priorities, it's time to begin incorporating your business as a C corp.

How to form a C corp

Setting up a C corp is a structured process that requires diligence, organisation and a keen understanding of state and federal requirements. It might seem tedious at times, but failure to adhere to the appropriate protocols will only complicate the process. Here's a run-through of the steps involved in forming a C corp:

1. Choose a business name

Forming a C corp begins with selecting a business name. It's important that the name distinguishes the corporation from other entities registered in the state of incorporation. Most states will also have stipulations surrounding the inclusion of specific designations within the name, such as "corporation", "incorporated", "limited" or abbreviations of these terms, signalling the business's formal status as a corporate entity.

2. Select a US state of incorporation

Deciding where to incorporate is pivotal. While many businesses default to the state in which they are based because of convenience and familiarity, some gravitate towards certain states that are renowned for their favourable business environments. Delaware, for instance, is a popular choice because of its advanced and flexible corporate laws, while Nevada offers benefits in terms of tax structures. California is another popular choice.

3. Designate a registered agent

Every C corp needs a registered agent – an individual or entity who is responsible for receiving legal papers, including litigation-related documents or official state communications. To qualify, the agent must maintain a physical address within the state of incorporation and be present at the business during normal office hours to receive and respond to official notices.

4. File articles of incorporation

This foundational document encompasses fundamental details, such as the business name, address, designated registered agent, and nature and number of stocks to be issued. A business must file the articles with the secretary of state's office or a similar governing body, and pay a filing fee to formalise the corporation's status.

5. Draft corporate bylaws

Bylaws serve as the corporation's internal rulebook. They dictate the operational procedures, delineate the rights and obligations of the shareholders, officers and directors, and set out the administrative framework of the business. Maintaining detailed and clear bylaws is important for transparency and conflict resolution.

6. Appoint directors

Directors play a pivotal role in steering the corporation and making significant decisions. Initially, the directors will normally be appointed by the incorporator or a group of individuals involved in forming the corporation. Typically, these initial appointees hold their positions until the corporation's first official shareholder meeting, at which point shareholders will elect the board of directors.

7. Conduct an organisational meeting

This initial meeting acts as a launchpad for the corporation's activities. Here, the directors adopt the previously drafted bylaws, appoint corporate officers to manage daily operations and address other pertinent startup matters, all while keeping detailed meeting minutes.

8. Issue stock

C corps issue shares to raise capital and provide ownership stakes. These shares, defined in the articles of incorporation, are distributed to initial shareholders and serve as evidence of their ownership in the corporation.

9. Apply for licences and permits

The nature and location of the business dictate the licences and permits that it requires. From city business licences to specialised permits, these legal documents authorise the corporation to operate within its industry and locale.

10. Register for state taxes

Tax obligations vary from state to state. If the state imposes a sales tax and the corporation deals in taxable goods or services, it must obtain a sales tax permit to collect tax from customers.

11. Obtain an employer identification number (EIN)

An EIN, often compared with a Social Security number for businesses, is a federal tax ID issued by the IRS. This number is a prerequisite for many business activities, from recruiting employees to filing federal tax returns.

12. Open a business bank account

Combining personal and business funds can be a serious mistake, and has the potential to undermine the limited liability shield that a corporation provides. Opening a dedicated business bank account is key to maintaining clear financial boundaries.

13. Remain compliant

Forming a C corp is just the beginning of a business's journey. To maintain its status, a corporation must adhere to state mandates consistently. This includes keeping updated corporate records, conducting and documenting annual meetings, and ensuring that all licences and permits remain valid.
