N.D. Admin. Code § 81-03-09-25 — Payroll factor - Compensation paid in this state

Compensation is paid in this state if any one of the following tests, applied consecutively, are met: 1. The employee's service is performed entirely within the state. 2. The employee's service is performed both within and without the state, but the service performed without the state is incidental to the employee's service within the state. The word "incidental" means any service which is temporary or transitory in nature, or which is rendered in connection with an isolated transaction. 3. If the employee's services are performed both within and without this state, the employee's compensation will be attributed to this state: a. If the employee's base of operations is in this state; or b. If there is no base of operations in any state in which some part of the service is performed, but the place from which the service is directed or controlled is in this state; or c. If the base of operations or the place from which the service is directed or controlled is not in any state in which some part of the service is performed but the employee's residence is in this state. The term "base of operation" is the place of more or less permanent nature from which the employee starts the employee's work and to which the employee customarily returns in order to receive instructions from the taxpayer or communications from the employee's customers or other persons or to replenish stock or other materials, repair equipment, or perform any other functions necessary to the exercise of the employee's trade or profession at some other point or points. The term "place from which the service is directed or controlled" refers to the place from which the power to direct or control is exercised by the taxpayer.
