Costs associated with forming a business varies by business entity type and by state the business was formed in. We aim to cover here the basic costs specific to the state for starting a business. We also touch upon other costs in order to stay compliant and continue to doing business in the state, such as paying various state taxes or complying with local minimum wage laws when hiring in-state.
We cover in broad strokes the following costs:
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.
Across all US states, the average cost of formation is roughly $100 with some states costing as little as ~$50 to create a corporation and some as high as $500+ to form an LLC.
Here are the formation costs (up to date at the time of this writing) for three most common entity types for businesses filed with the state:
Franchise taxes are state fees that businesses pay in order to have the right to operate in those states. They are paid in addition to state and federal income taxes. Failure to file can cause a business to lose its good standing with the state, making it difficult to operate, get loans, and may cost the business clients if clients require this information.
Here are the franchise tax fees for each business entity structure in this state as of the time of this writing.
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.
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.
If you're considering hiring employees for in-person work, then knowing your state's employment laws are important.
