South Dakota lesson 5 of 6
South Dakota LLC taxes, sales tax and licensing
South Dakota has no personal or corporate income tax, which means an LLC's pass-through profit is never taxed at the state level, only federally. Sales tax and local licensing are where a South Dakota LLC still has real compliance work to do.
No state income tax on members or the LLC
Members of a South Dakota LLC taxed as a partnership or sole proprietorship for federal purposes pay no South Dakota personal income tax on their share of profit, because the state does not levy one. An LLC that elects C corporation tax treatment for federal purposes also owes no South Dakota corporate income tax, since South Dakota does not tax corporate income either. This is one of the state's main draws for LLCs and trust structures owned by people who live elsewhere.
Sales tax, currently 4.2% and scheduled to change
South Dakota's statewide sales and use tax rate was reduced from 4.5% to 4.2% effective July 1, 2023 under House Bill 1137, which included a sunset clause. Unless the legislature acts again, the rate reverts to 4.5% on July 1, 2027. Municipalities can layer their own local sales tax on top of the state rate, so the total rate a customer pays depends on where the sale is sourced.
South Dakota's sales tax reaches many services, not only goods, including many types of consulting and professional services. Confirm whether your specific service is taxable on the Department of Revenue's sales and use tax guide before assuming it is exempt.
There is no general statewide business license in South Dakota. Licensing depends on your industry, and some cities and counties layer on their own local licensing.

- The state sales tax rate is currently 4.2% and is scheduled to revert to 4.5% on July 1, 2027 absent further legislative action.

Does South Dakota tax LLC pass-through income?
No. South Dakota has no state personal income tax, so pass-through LLC profit is only taxed federally for its members.
