Oregon Revised Statutes Labor and Employment; Unlawful Discrimination § 657.095

(1) As used in this chapter, unless the context requires otherwise, “payroll” means all wages paid to employees in any employment subject to this chapter. However, for payroll tax purposes pursuant to this chapter, “wages” excludes remuneration received by an employee from each employer in any calendar year that is in excess of an amount obtained by multiplying the average annual wage for the second preceding calendar year by 0.80 and rounding the result to the nearest multiple of $100. The average annual wage shall be determined by dividing the total wages paid by subject employers during the year by the average monthly employment reported by subject employers for the year. However, a payroll, as calculated pursuant to this section, may not in any year be less than the amount in effect during the preceding calendar year.

(2) The remuneration paid by an employer located in this state for work performed in other states by an employee who works part of the time in a calendar year in this and other states shall be included in payroll when the work in the other states is covered by unemployment insurance laws. The Director of the Employment Department shall prescribe the manner of providing proof of the payment of payroll taxes on the wages of an employee earned while working in other states.
