State Approach

South Dakota law aligns closely with federal tax principles as set out in Cundiff v. Commissioner by recognizing the deductibility of certain expenses related to trade or business. However, South Dakota's lack of a state income tax negates some considerations present in Cundiff's application of federal tax law.
