modify provisions for a tax collection agreement with an Indian tribe.

HB 1233 modifies South Dakota's tax collection agreements with Indian tribes by expanding the list of state taxes tribes can collect on behalf of the state. The bill adds 13 specific taxes to the existing list, including retail sales tax, cigarette tax, motor vehicle excise tax, and remote seller sales tax. Under the agreement, tribes would collect these taxes and the state would retain a set percentage of the collected revenue as an administrative fee. This directly affects tribal governments (as tax collectors) and South Dakota's Department of Revenue (as the state entity managing collections).
