Oregon Revised Statutes Public Officers and Employees § 237.637

(1) Any public employer that provides retirement benefits to its police officers and firefighters other than by participation in the Public Employees Retirement System pursuant to the provisions of ORS 237.620 shall provide increases to the police officers and firefighters of the public employer, both active and retired, that are equal to the increases in retirement benefits that are provided for in chapter 569, Oregon Laws 1995, for active and retired police officers or firefighters who are members of the Public Employees Retirement System, or the public employer shall provide to those police officers and firefighters increases in retirement benefits that are the actuarial equivalent of the increases in retirement benefits that are provided for in chapter 569, Oregon Laws 1995, for police officers or firefighters who are members of the Public Employees Retirement System. Increases provided under this section shall be reduced by the amount of any benefit increase provided by ORS 237.635 in the same manner that increases in retirement benefits that are provided for in chapter 569, Oregon Laws 1995, for active and retired police officers or firefighters who are members of the Public Employees Retirement System are reduced to reflect amounts paid to those members under the provisions of chapter 796, Oregon Laws 1991. No other retirement benefit or other benefit provided by those public employers shall be decreased by the employer by reason of the increases mandated by this section.

(2) A public employer that is subject to the requirements of this section shall cease paying increased retirement benefits under this section if the payments made to the person are not subject to Oregon personal income tax under ORS 316.127 (9). A public employer that is subject to the requirements of this section shall adopt procedures similar to those described in ORS 238.372 to 238.384 for the purpose of implementing this subsection. The Department of Revenue shall provide to a public employer that is subject to the requirements of this section the information regarding Oregon personal income tax returns that the public employer deems necessary to determine whether the retirement benefits paid to the person by the public employer are subject to Oregon personal income tax under ORS 316.127 (9).
