2017 ORS 319.300¹
Seller to give invoice for each purchase made by person entitled to refund

(1) When motor vehicle fuel is sold to a person who claims to be entitled to a refund of the tax imposed, the seller of the motor vehicle fuel shall make and deliver at the time of the sale separate invoices for each purchase in such form and containing any information prescribed by the Department of Transportation.

(2) The invoices shall be legibly written and shall be void if any corrections or erasures appear on the face thereof. Any person who alters any part of any invoice that will tend to give to the claimant an illegal gain, shall have the entire claim invalidated. The seller shall for a period of at least 18 months retain copies of all invoices and make them available to the department upon request. [Amended by 1953 c.77 §2; 1955 c.730 §10; 1957 c.209 §7]
