OAR 150-316-0257: Employer’s Election of Method of Computing Withholding

(1) Employers have the option of using either the tax tables or the formulas developed and furnished by the department in computing the amount to be withheld from regular wage payments. The tax tables and formulas are published by the department. Employers may not modify the published tables or formulas. (2) If a supplemental wage payment is made on or after January 1, 2020, the employer may compute the amount to be withheld by using the tax tables or formulas, or may withhold at a flat rate of 8 percent. Supplemental wage payments include bonuses, premiums, awards, gifts and other payments made to an employee, on the condition of their employment, occurring no more than twice a year.
