South Dakota Administrative Rules — Title 64 (Revenue)
ARSD § 64:06:01:06 — Casual or occasional sales
Casual or
occasional sales made by an individual who is not engaged in the business of
selling at retail are not subject to the tax. Tax applies on sales made in the
course of a regularly conducted retail business.
Unless sales are of such a number,
volume, or frequency as to indicate evasion of the tax, they are not taxable. A
jobber or wholesaler who sells direct to a consumer is a retailer for that
portion of the jobber's or wholesaler's business.
Each case must stand upon its own
facts, but good faith is required. Taxability is the rule rather than the
exception, and the rule of reason applies.
