Oregon Revised Statutes Public Health and Safety § 461.560

(1) No state or local taxes shall be imposed upon the sale of lottery tickets or shares of the Oregon State Lottery established by this chapter or any prize awarded by the state lottery established by this chapter that does not exceed $600. A prize awarded by the state lottery that is greater than $600 shall be subject to tax under ORS chapters 314 to 318 and any other applicable state or local tax. For purposes of this section, “prize awarded by the state lottery” includes a prize awarded by a multistate lottery association of which the Oregon State Lottery is a member if the ticket upon which the prize is awarded was sold in this state.

(2) A city, county or other political subdivision in this state may not impose, by charter provision or ordinance, or collect a tax that is imposed on lottery game retailers only and that is measured by or based upon the amount of the commissions or other compensation received by lottery game retailers for selling tickets or shares in lottery games. However, if a city, county or other political subdivision levies or imposes generally on a nondiscriminatory basis throughout the jurisdiction of the taxing authority an income, gross income or gross receipts tax, as otherwise provided by law, such tax may be levied or imposed upon lottery game retailers.
