Location Matters 2021 – The State Tax Cost of Doing Business produced by the Tax Foundation and KPMG provides a comparative analysis of actual state business tax costs faced by businesses. The study accounts for all business taxes including corporate income, property, sales, unemployment insurance, capital stock, inventory, and gross receipts taxes. Economists designed eight model firms, and modeled each firm twice in each state: once as a new firm eligible for tax incentives and once as a mature firm not eligible for such incentives.
In South Dakota, five of the eight mature firms modeled rank in the top 10 for lowest tax burdens – corporate headquarters, technology centers, data centers, capital-intensive manufacturing and labor-intensive manufacturing.
