What kind of entity should you form for your business? While each entity formation offers its own benefits, forming a Corporation (also referred to as a general for-profit corporation or C Corporation), is a common entity chosen by new businesses.

One of the reasons for the entity's popularity is that a corporation provides a business with a great deal of structure. A corporation can deduct certain benefits, like employee health insurance and dental plans, which can add up to substantial tax savings per year. Additionally, corporations allow the issuance of stock, which helps attract investors and venture capitalists that may want to invest in your business.

Corporations may also enter legal contracts, borrow money or take out loans, hire employees, and create initial public offerings (IPOs) to take their businesses public.

The Benefits of a Corporation

  • Limit your legal and fiscal responsibility.
    Incorporating your business separates you from your business as a separate legal entity, preventing you from being fully responsible for any debts accrued by your business.
  • Build Credibility
    Adding a corporate indicator like "INC." at the end of your business name immediately indicates credibility to potential investors, customers, or business partners.
  • Potential tax advantages
    Forming a corporation may provide a tax advantage for some businesses, allowing additional deductions for operating expenses, advertising, employee compensation, and more.

The next step will be to decide on a name for your business. Choose a name that is memorable and unique, easy to understand and pronounce, and accurately represents your business. You'll want to search your name choices on the web to quickly find out if they are already taken. It's also best to jot down one or two alternatives, in case the name you settle on is not available for registration in South Dakota.

The name you choose must be unique and not "confusingly similar" to the name of any other South Dakota business. This is to prevent fraud or misrepresentation and is a common rule in all 50 states. You can find out whether your name is available by searching the South Dakota business name availabilty tool for possible conflicts. Be sure to check variations or alternate spellings as well, otherwise your filing may be rejected. In a pinch, you can use MyCorporation's business name search service, where we will conduct a more thorough search on your behalf and report back our findings. Plus, MyCorporation includes a business name search for free when we complete your LLC filings on your behalf!

For a South Dakota corporation, you must include one of the following endings: "corporation," "incorporated," "company," "limited," or the applicable abbreviation.

You can learn more about how to choose and register a business name and other important statutory information through the South Dakota Secretary of State.

Tip: A business name check is included with every one of our business formation packages. We check with the state to determine the availability of your business name automatically. You can also conduct a nationwide business name search here.

Most states require that you designate a registered agent for your business, and South Dakota is no exception. A registered agent acts as the state's means to communicate with a business and is responsible for receiving legal and official documents related to the business.

A registered agent can be anyone you wish, with one small caveat. The registered agent must have a physical address in South Dakota. In other words, a P.O. Box is not allowed as a registered agent address. This means a member of the corporation can act as the registered agent if desired, or a third-party registered agent service like MyCorporation can be used.

Why designate a third party to act as my registered agent?

It should be noted that registered agent information is made publicly available. This can cause privacy concerns for business owners who do not wish to list their personal contact information on the internet for everyone to see. It is also common for the registered agent to become a target of spam or robocalls since this private information is relatively easy to obtain. Another issue that may arise is that in the case of a lawsuit, these documents would be hand delivered directly to the registered agent, and in the case that you used your business location for this purpose, this could occur in front of your customers. This is why many business owners opt for a third-party registered agent service such as MyCorporation to act as a registered agent on behalf of their business.

Corporate bylaws are a detailed set of rules agreed upon and adopted by the board of directors after a corporation is formed, that specify the internal management structure of the corporation. They are typically drafted by the corporation's founder or directors. Corporate bylaws are not submitted to the state.

The state of South Dakota does not require a corporation to create bylaws upon approval of the Certificate of Incorporation, but it is strongly recommended. Bylaws allow a business to maintain consistency in the way it operates and communicate organizational rules to help avoid conflicts and disputes. They cover how directors are elected, meetings are organized, and officer roster and summary of duties. In addition to management, bylaws specify details about ownership rights, annual meetings, and the addition or removal of officers and directors.

If you are not sure how to create corporate bylaws, you can purchase MyCorporation's customized Minutes and Bylaws Package. This kit provides you with the internal documents required to fulfill your corporate formalities and properly operate your business after incorporating.

The board of directors of a corporation are normally elected by the shareholders. However, for a new business, the incorporator (the person who signed the Certificate of incorporation) will often designate the initial directors if there are no initial directors named in the certificate of incorporation. This is done by creating the "Statement of Incorporator" which will list the names and addresses of the initial directors of the business. The statement of incorporator is then signed by all of the incorporators, which passes all elements of control over to the initial directors. This is filed not with the state, but in a corporate minute book of the incorporation. It is kept as part of the corporate record.

The first meeting of the board of directors is an important time in the life cycle of a corporation. During this meeting, the initial directors of the business will adopt the corporate bylaws, set the fiscal year, and appoint corporate officers. It is also common to authorize the issuance of shares of stock to the founders of your company, usually in exchange for assets.

This meeting, and all future meetings of the board of directors, must be recorded in corporate minutes. Minutes are documents that detail what was discussed and any decisions the business makes during meetings. They are stored with the corporate records.

Corporate minutes are required for all South Dakota corporations by law. Falling behind on keeping and maintain minutes can jeopardize the corporation's liability protection and overall tax advantages. It is important to maintain updated corporate minutes and keep copies of all the signed and approved minutes or actions by unanimous consent from any special or annual meetings of the corporation's shareholders and directors.

Stock is a representation of ownership in your corporation. When your shareholders purchase stock, they are buying a small piece of your business. Although it's not legally required, it is common that most corporations will issue paper stock certificates to their shareholders.

In a private company (not publicly traded on the stock market), you can set the value to each stock however you see fit in your corporate bylaws. For example, one share could be worth $10 or $10,000, either would be completely acceptable. If you have additional questions, you may contact the South Dakota Secretary of State to learn more.

Tip: MyCorporation can help you issue stock certificates for your business, allowing you to raise money by way of outside investment.

Your South Dakota corporation may need to check in with the South Dakota Secretary of State for more information about the licenses and/or permits required by your business. Several factors, including the company's industry and county location, may determine which documents need to be filed.

In the event you need some assistance, you may also use MyCorporation's business license compliance package. Our skilled professionals will do the work for you. We identify all of the licenses required by your business and provide you with the information you need in order to file.

An EIN (also referred to as a Federal Tax ID) is a nine-digit number that is issued by the IRS and used to uniquely identify your business for tax purposes. Think of it as a Social Security Number (SSN) for your business, except an EIN is less sensitive. It is important to wait until the LLC has been approved by the state before applying for an EIN. For that reason, filing for an EIN is one of the last things to do when you are setting up a business.

  • Open business checking, savings, or investment accounts
  • File taxes for the business
  • Complete payroll for employees if applicable
  • Obtain lines of credit and credit cards, as well as "build credit" for your business
  • Apply for applicable business licenses when required.

You will only need a few pieces of information to file including your mailing address and legal business name. You can apply online with the IRS by downloading IRS Form SS-4, or work alongside a third party organization like MyCorporation to complete an EIN application.
