Sales-tax license

South Dakota requires a sales-tax license for taxable business activity. The state sales and use tax rate is generally 4.2%, with possible municipal taxes. A physical presence can trigger licensing without a sales threshold. Remote sellers generally need a license after more than $100,000 in South Dakota gross sales in the previous or current calendar year.

Contractor’s excise tax

Construction and certain real-property improvement businesses should separately review contractor’s excise tax licensing and reporting. A sales-tax license alone does not answer every contractor requirement.

No universal business license

South Dakota does not use one license that covers every LLC. Check Department of Revenue tax licenses, professional boards, local rules, and specialized agency permits based on the actual activity.

Employer setup

An EIN does not create South Dakota unemployment insurance, wage reporting, or workers’ compensation compliance. Review South Dakota Department of Labor and Regulation requirements when hiring.
