What is an S-Corporation?

An S-Corporation is a type of corporation that elects to be taxed under Subchapter S of the Internal Revenue Code. This tax treatment allows S-Corporations to enjoy pass-through taxation, meaning the corporation’s income, deductions, and credits flow through to the shareholders, who report this information on their individual tax returns. This structure helps to avoid the double taxation experienced by C-Corporations.

An S corporation (S corp) is not a type of corporate entity, unlike a limited liability company (LLC) or other companies. It’s a tax classification that might result in significant financial savings for corporations and LLCs but in different ways. S-corp is similar to LLC, except that the IRS treats it as a corporation for tax purposes.

  4. Other Costs: Depending on the nature of your business, additional costs may include obtaining licenses and permits, registered agent services, and professional fees for legal and accounting services.

Advantages of Forming an S-Corporation

There are numerous advantages to incorporating an S-Corp, but you should be aware of certain problems. Consider the following benefits of an S corporation:

Pass-through Taxation

S-Corporations enjoy pass-through taxation, which helps to avoid the double taxation faced by C-Corporations. This can result in potential tax savings for shareholders. Pass-through taxation is a tax system where the income, deductions, and credits generated by a business entity, such as Oklahoma General Partnership, limited liability company (LLC), or S-Corporation, are passed through to individual owners or shareholders instead of being taxed at the corporate level.

In this system, business profits and losses are reported on the owners’ or shareholders’ individual tax returns, and taxes are paid at their individual income tax rates. This avoids the issue of double taxation, which occurs in C-Corporations where income is taxed at both the corporate level and again when distributed to shareholders as dividends. Pass-through taxation is generally advantageous for small businesses and their owners, as it simplifies tax filings and often results in lower overall taxes.

Limited Liability Protection

Shareholders of an S-Corporation have limited liability protection, meaning their personal assets are protected from the corporation’s debts and obligations. Limited liability protection in an S-Corporation refers to the legal separation between the personal assets of the shareholders (owners) and the business assets, which protects shareholders from being personally responsible for the company’s debts and legal obligations.

In an S-Corporation, shareholders’ personal assets, such as their homes, cars, and personal savings, are not at risk if the business faces financial difficulties or lawsuits. The shareholders’ liability is limited to the amount they have invested in the company. This limited liability is a significant advantage of incorporating a business as an S-Corporation, as it provides a safeguard for the personal financial well-being of the business owners.

It is important to note that limited liability protection can only be supported if the shareholders maintain proper corporate formalities, such as keeping separate business and personal finances, holding regular shareholder meetings, and maintaining accurate business records. In such cases, courts may “pierce the corporate veil” and hold shareholders personally liable for the company’s debts and obligations.

Transferability of Shares

Shares in an S-Corporation are more easily transferable than those in an LLC, allowing for greater flexibility in ownership changes. Transferability of shares in an S-Corporation refers to the ability of shareholders to sell, gift, or otherwise transfer their ownership interest in the company to another person or entity. This is an important aspect of an S-Corporation’s structure, as it allows for flexibility in ownership and the potential for raising capital through the sale of shares.

However, there are certain restrictions on the transferability of shares in an S-Corporation, which are imposed by the Internal Revenue Service (IRS) to maintain the company’s eligibility for S-Corp status:

  • Shareholders: The number of shareholders in an S-Corporation is limited to a maximum of 100. Only individuals, certain trusts, and estates can be shareholders; other corporations and partnerships are generally not allowed.
  • Eligible Shareholders: Only U.S. citizens and resident aliens can be shareholders in an S-Corporation. Non-resident aliens are not allowed to hold shares.
  • One Class of Stock: S-Corporations can only have one class of stock. All shares must have the same rights and privileges, such as voting rights and distribution preferences. However, differences in voting rights are allowed if they are not tied to economic rights (e.g., distribution preferences).
  • Perpetual Existence: Perpetual existence refers to the concept that a business entity, such as an S-Corporation, can continue to exist indefinitely, regardless of changes in ownership or management. This means the corporation can outlive its original founders and shareholders and continue to operate even if individual shareholders pass away or decide to sell their shares.

This characteristic of an S-Corporation provides stability and continuity for the business, as it ensures that the corporation’s operations, contracts, and legal obligations remain unaffected by changes in ownership. It also makes it easier for the company to attract investors and raise capital. Potential investors can be confident that the business will continue to exist even if the original owners are no longer involved.

Disadvantages of Forming an S-Corporation

Despite these advantages, moving to an S corporation only sometimes makes sense – or at the very least, necessitates a thorough review of certain situations. The following issues may arise in particular:

Restrictions on Shareholders

S-Corporations are subject to specific restrictions, such as a maximum of 100 shareholders and limitations on the types of eligible shareholders (e.g., only individuals, certain trusts, and estates).

Single Class of Stock

S-Corporations are limited to issuing only one class of stock, which can limit flexibility in raising capital or creating different ownership structures. A single class of stock in an S-Corporation refers to the requirement that the corporation only issues one type of stock with equal rights and characteristics for all shareholders. This means that all shares of stock must have the same economic rights, such as dividend distribution preferences and liquidation rights, as well as voting rights. The single class of stock requirement is one of the key criteria the Internal Revenue Service (IRS) sets for a corporation to qualify for S-Corp status.

Increased Complexity

Forming and maintaining an S-Corporation requires more paperwork, record-keeping, and compliance with state and federal regulations than simpler structures like LLCs.

Franchise Tax

S-Corporations in Oklahoma are subject to the annual franchise tax, which can financially burden some businesses.

In an Oklahoma S-Corporation context, the franchise tax is usually based on the company’s income, net worth, or a combination of both. Since S-Corporations are pass-through entities for federal income tax purposes, meaning that their income is not taxed at the corporate level but rather passed through to individual shareholders, they may be exempt from or subject to lower franchise tax rates in some states than traditional C-Corporations.

However, S-Corporations must still comply with Oklahoma franchise tax requirements, which may include annual filings and tax payments. It is crucial for S-Corporation owners to understand the specific rules and regulations in their state of operation and to consult with a tax professional to ensure compliance and minimize their tax.

In addition to tax benefits, S Corporations in Oklahoma also offer limited liability protection for their shareholders. This means that the personal assets of the shareholders are typically protected from any business debts or liabilities.

Furthermore, starting an S Corp in Oklahoma can offer more credibility and professionalism for your business. By establishing your company as a legal entity, you can show customers, partners, and investors that you are serious about your business and are committed to following proper legal procedures.
