A corporate name in South Dakota:
- Must contain the word “Corporation,” “Incorporated,” “Company,” or an acceptable abbreviation (e.g., Corp, Inc, Co, etc.).
- Cannot contain a word or phrase that implies that it was organized for a purpose that is not permitted by § 47-1A-301, as well as a purpose that is contrary to its Articles of Incorporation.
- Must be different from the names of other domestic corporations, as well as from fictitious names adapted by foreign corporations authorized to transact business within South Dakota.
- Cannot contain words that are obscene, offensive, or incriminatory, as well as words that suggest or state that the corporation is affiliated with state or government agencies.

Read the South Dakota state statute regarding corporation naming guidelines for more information.
2. Is my corporation name available in South Dakota?
Your South Dakota corporation name must be unique and distinguishable from other business names in South Dakota. Use the South Dakota Secretary of State’s Business Search Portal to determine if your desired business name is available.
3. Is the URL available?
Before registering your South Dakota corporation, you’ll need to check if a good URL is available for your business name. It’s important to secure your URL right away.
Step 2: Choose a South Dakota Registered Agent
You must appoint a South Dakota registered agent when registering your corporation with the Domestic Business Corporation.
A registered agent is an individual or entity appointed to receive service of process, government correspondence, and compliance documents on behalf of a business.
Your registered agent can be an individual, business entity, or professional registered agent service. Any member of the corporation or individual can serve as your South Dakota registered agent as long as the person:
- is 18 years or older
- has a physical address in the state where business activity is conducted
- is available (in person) during normal business hours
Recommended: Northwest offers one year of free registered agent services with their corporation formation package ($29 + State Fees).
Step 3: Hold an Organizational Meeting
Before you officially file the Articles of Incorporation in Step 4, you will need to hold an organizational meeting to complete the following tasks:
- Fill out and execute the Articles of Incorporation
- Create and approve bylaws
- Select your initial director(s)
- Determine your share structure
- Execute an Incorporator’s Statement
Create and Approve Corporate Bylaws
Bylaws are the rules that determine how your organization will be governed and run. For detailed instructions on creating your bylaws, read our corporate bylaws guide.
Appoint Initial Directors
You must appoint at least one director who will oversee your South Dakota corporation until the first shareholder meeting.
A corporate director is in charge of the adoption, amendment, and repeal of operational bylaws as well as the election, supervision, and removal of officers.
After forming the corporation, the incorporator(s) — or initial director(s), if named on the formation documents — should call an organizational meeting. During this initial meeting, either the incorporator(s) will elect the board of directors or the initial director(s) will appoint the officers.
Choose a Share Structure and Strategy
A share of stock is the unit of ownership of a corporation. Each share of stock represents a percentage of ownership of the company. For example, if a corporation issues one share of stock the shareholder (stock owner) would then own 100% of the corporation.
Shares can be structured into classes. Each class, termed a share class, holds different rights and privileges. You can have multiple classes and each class can hold any number of shares.
Authorized Shares: the number of shares the corporation is allowed to issue.
Issued Shares: the total number of shares actually issued to shareholders.
Share Class: a group of shares that has a unique set of rights and privileges.
The Articles of Incorporation form issued by the South Dakota Secretary of State can only be used to start a corporation with one share class. If the corporation needs a multiple share class structure, you must attach an additional provision to your Articles of Incorporation.
Create and Execute an Incorporator’s Statement
The incorporator(s) should sign an Incorporator’s Statement with complete names and addresses of each initial director and store it in the corporate records book.
This document names the initial director(s) that will serve until the board of directors is elected during the first shareholder meeting. It should be stored with the rest of your corporate records.
Step 4: File the South Dakota Articles of Incorporation
You will need to file the South Dakota Articles of Incorporation to set up a corporation in South Dakota. You may file it by mail or online with the South Dakota Secretary of State. The filing cost is $150 for online filings and $165 for mailed filings.

South Dakota Corporation FAQ
The cost of starting a South Dakota corporation will depend on how you go about filing your Articles of Incorporation, as well as on who your registered agent is.
Filing online costs $150, whereas an additional $15 needs to be paid for applications sent via mail.
The cost of a registered agent will depend on whether you become your own registered agent, use a partner or business attorney, or use a registered agent service.
The main difference between an LLC and a corporation comes down to taxes:
- LLCs are pass-through entities that are taxed similarly to sole proprietorships and general partnerships (depending on how many members they have).
- Corporations are required to pay corporation taxes while the shareholders pay income taxes on dividends they receive.
Corporations also need to follow significantly more guidelines when operating and are more expensive to maintain.
See our S Corp vs. C Corp vs. LLC comparison for more information.
According to the South Dakota Secretary of State’s website, it will take between three and five business days on average for them to process your Articles of Incorporation if you are filing via mail.
Online filings, on the other hand, are processed immediately.
For more information on everything you need to know to start a corporation, see our How to Start a South Dakota Corporation article.
Not really. You should be able to start a corporation independently by:
- Choosing a legally compliant business name
- Appointing a registered agent (this can also be a registered agent service)
- Filing the Articles of Incorporation
- Holding an organizational meeting
Having said that, starting a corporation is still likely to be more time-consuming and expensive in comparison to other entities.
For most new business owners, yes. This is because starting a corporation can be a lot more expensive than forming an LLC and is subject to significantly more rigmarole when it comes to how it operates.
Generally speaking, an LLC is always recommended over a corporation. The only exception to this is if you’re looking to attract private investors.
