How to Get a Business License in South Dakota (2026)

Fact-checked by the LegalGlass editorial team against primary sources · Published Aug 6, 2026 · Last updated Aug 6, 2026

South Dakota has no general statewide business license. Most businesses instead need a state sales and use tax license from the South Dakota Department of Revenue before making taxable sales, plus any local and professional licenses. South Dakota has no state income tax, and construction work carries a 2% contractor's excise tax.

Is There a South Dakota Business License?

New owners often look for "the South Dakota business license," a single permit that covers the whole business. It does not exist. South Dakota does not issue a general statewide business license. Instead, your obligations are a set of separate registrations that depend on what you sell, where you operate, and whether your profession is regulated. The most common state registration is a sales and use tax license from the Department of Revenue. Certain construction businesses also register for the contractor's excise tax. On top of that, some cities require local licenses, and regulated professions need a state board license.

South Dakota is notable for being a low-tax state: it has no state personal income tax and no corporate income tax. That does not mean there is nothing to register for. Sales and use tax, the contractor's excise tax, property tax, and federal taxes still apply. This guide separates the layers, in the order most South Dakota owners handle them, and cites the official agency for each step. For the national picture, see the business license overview and how to form an LLC.

Register Your Entity and Get an EIN First

Licensing sits on top of your business entity, so handle that first. If you form an LLC or a corporation, you register it with the South Dakota Secretary of State through its online business portal. A sole proprietor has no state formation filing but still handles taxes and any local license. If you operate under a name different from your legal entity name, you may register a fictitious business name (DBA) with the Secretary of State.

Next, obtain a federal Employer Identification Number (EIN). The IRS issues the EIN free, and South Dakota tax licensing, banking, and hiring all use it. By default the IRS treats a single-member LLC as a disregarded entity and a multi-member LLC as a partnership, and either can elect S-corporation treatment. A single-owner business without employees may sometimes use a Social Security number or ITIN, but most businesses need an EIN before they apply for a state tax license. Keep your formation documents, EIN letter, and licenses together with your other business records. Also appoint and maintain a registered agent if you form an entity.

The South Dakota Sales and Use Tax License

If your business sells taxable goods or provides taxable services, the key state registration is a sales and use tax license. You apply through the South Dakota Department of Revenue, and there is no fee to obtain the license. You must hold the license before making taxable sales. During the application you provide your entity details, EIN, ownership, and a description of your activity, and the Department sets up your tax account and filing frequency.

South Dakota taxes a broad base, including many services that other states exempt, so do not assume your offering is untaxed. The state sets the sales and use tax rate by statute, and many municipalities add a local sales tax, so the combined rate depends on where the sale occurs. Because the state rate and local rates can change, confirm the current figures on the Department of Revenue's sales tax pages rather than relying on a third party. Remote sellers with enough sales into South Dakota can also trigger a registration obligation under the economic nexus rules the state pioneered. For how sales and other business taxes fit into your filing calendar, see business tax basics.

Contractor's Excise Tax, Local, and Professional Licenses

Construction businesses face an extra layer. South Dakota imposes a 2% contractor's excise tax on the gross receipts of construction services and realty improvement projects. Contractors register for this tax with the Department of Revenue; it is separate from sales and use tax, and prime contractors and subcontractors should understand how it applies before bidding a job. Materials used in construction generally carry sales or use tax as well, so builders often manage both.

The next layer is local. Some South Dakota cities and counties require local business licenses, permits, or zoning approvals for certain activities, though many small businesses will not need one. Requirements vary, so contact the city finance office or county where you operate. The final layer is professional and occupational: South Dakota regulates many professions and trades through state boards, including contractors in specific trades, cosmetologists, real estate agents, accountants, and health professionals. A regulated professional must hold the applicable board license to operate lawfully, even if the entity and tax license are in order. Some activities, such as selling alcohol or tobacco, require specialty state permits. Use the U.S. Small Business Administration's licensing overview to catch any federal requirement, such as alcohol, firearms, or transportation, that layers on top of state and local licenses.

Step-by-Step: Getting Licensed in South Dakota

Here is the order most South Dakota owners follow to become fully licensed and registered.

1. Register your entity and get an EIN. Form your LLC or corporation with the Secretary of State (or operate as a sole proprietor) and get a free EIN from the IRS.
2. Apply for a sales and use tax license. If you make taxable sales, apply with the Department of Revenue before your first sale. There is no fee.
3. Register for contractor's excise tax if applicable. Construction and realty improvement businesses register for the 2% excise tax.
4. Get local licenses. Contact each city and county where you operate for any local license, permit, or zoning approval.
5. Obtain professional or specialty licenses. Apply to the relevant state board if your profession is regulated, and secure any alcohol, tobacco, or federal permits.

When you close the business, cancel your tax licenses and follow the state's dissolution steps so obligations stop cleanly. Leaving a sales tax license active after you stop operating can generate delinquency notices for unfiled returns, so formally close each registration you no longer need.

Two points make South Dakota easier to plan for than higher-tax states. First, because there is no state income tax, you will not file a state business income return, though you still report federal income to the IRS and pay self-employment tax on pass-through earnings. Second, the sales and use tax license itself is free and fast to obtain, so the friction of getting started is mostly about identifying whether your specific service is taxable and whether a local license applies. Contractors are the main group with an extra step, because the 2% contractor's excise tax and the sales or use tax on building materials both come into play on a typical project. Mapping those obligations before you bid keeps your pricing accurate and your filings clean.
