Costs of Forming Business Entities in South Dakota

There are several types of business structures you can choose from when forming your business. Which is best for your business depends on a variety of factors, like ownership in the business, taxation, and more.

No State Filing: There are two types of structures which can be automatically formed without any filing with the state. Sole proprietorship and general partnership falls into this category, and they are a popular form of self-employment.

Formed or Incorporated: Three most common business entities that require some formation or incorporation with the state are corporation, limited liability partnership (LLP), and limited liability company (LLC). Each structure has its own one-time formation or set-up cost.

South Dakota offers the basic entity types that businesses can choose from in any state when filing for a domestic entity setup: Corporation (for profit and nonprofit), LLP, LP, and LLC. There are additional variations for each of these entity types as well as other structures, like series LLCs. South Dakota also recognizes Cooperatives and Business Trusts.

Medical professionals may form a professional corporation, an LLC, or an LLP. Lawyers and accountants may form a professional corporation or an LLC. The name of a professional corporation should contain the words “professional company” or “professional corporation” or abbreviations such as “Prof. Co.,” “Prof. Corp.,” “P.C.,” or “PC.” The name of a PLLC should contain the words “professional limited liability company” or the abbreviation “Prof. L.L.C.,” “Prof. LLC,” “P.L.L.C.,” “PLLC.“ The name of any professional LLP must end with the words, “Professional Limited Liability Partnership,” or the abbreviation, “P.L.L.P.,” or the words, “Limited Liability Partnership,” or the abbreviation, “L.L.P.”

Domestic and foreign corporations, LLCs, and nonprofits can be formed predominantly online at the Business Services Portal operated by South Dakota’s Secretary of State. Follow their New Business flow to form an entity. Any other entities will need to fill out the applicable forms available here and mail in the documentation and payment to the SoS.

South Dakota Annual Reporting Fees

In many states, business entities must file an annual report. Annual reports are short documents that provide updated information about your business, including the name and address of the business, the people who run it, and its registered agent. Keeping this information up to date ensures you stay compliant.

The most cost efficient way to report annually is to do it yourself. However, plenty of services also provide support to do this on your business' behalf. Here are the costs for annual filings for the state for the most common business entities at the time of this writing. Where costs are not flat, we provide general information on how the fee is structured.

South Dakota State Income Tax

Taxes, taxes, and more taxes. Although income taxes may seem far off concern when starting a business, the truth is that not withholding enough for income taxes is a material cost to business owners. Here we briefly cover state income taxes. For a better overview of self-employment taxes, you can read more on Small Business Tax Planning.

Pass-Through Entities: Pass-through entities are boon to small business owners. A pass-through entity is a business structure where income passes directly to the owners or investors, and they report it on their personal tax returns. This allows the business to avoid paying corporate taxes, making it a more tax-efficient option for small businesses. This also makes filing taxes significantly simpler as only one return is needed.

By default, sole proprietorships, LLCs, and partnerships are considered pass-through entities. In the case of LLCs, LLCs are usually referred to as disregarded entities. However, owners can choose to get their LLC be recognized and treated differently for tax purposes with the IRS.

Corporate Income Tax:
Most states (44 out of 50) levy a corporate income tax.
C-Corps pay a C-Corp state income tax rate. If the income tax is pass-through, as with S-Corps, use your personal income tax rate.

Limited Liability Companies: For LLCs, the tax rate depends on the how you set up the LLC business structure.

  • Multi-member LLC: treated as a partnership (pass-through). Each person pays personal income tax based on their share of the LLC's income and their own personal income tax rate.
  • LLCs as S-Corps: if the LLC elects to be taxed as an S-Corp (pass-through), the LLC is taxed at the personal income tax rate.
  • LLCs as C-Corps: if the LLC elects to be taxed as a C-Corp, the LLC is taxed at the C-corp income tax rate.

South Dakota Sales Tax

Business owners who sell goods or services within a state are typically required to collect and remit state sales tax. Each state has different rules regarding what is taxable, so it’s crucial to understand the state’s specific requirements. Most businesses aren't at significant risk of non-compliance with sales tax until they reach the state's economic nexus threshold.

Economic nexus refers to the threshold of sales or transactions in a state that, once exceeded, obligates a business to collect sales tax, even if they don't have a physical presence there. Once a business achieves economic nexus, they must register with the state’s tax authority and start collecting sales tax on applicable sales. Failing to comply with these requirements can result in penalties and back taxes. Economic nexus is particular important when it comes to online sales for e-commerce companies.
