Income Tax for Oregon

The 1991 Oregon Legislature made PERS benefits subject to state income tax. The Oregon Supreme Court ruled that benefits for service after September 29, 1991, can be taxed. Benefits for service performed before September 29, 1991, can be taxed only if a "remedy" was provided.

To compensate for Oregon personal income taxation, the 1995 Legislature passed HB 3349, which provides a 9.8901 percent benefit increase on benefits earned before October 1991. All retirement benefits reflect this increase where applicable. Individuals who became members after July 14, 1995, are not eligible for HB 3349 benefit increases. HB 3349 benefit increases do not apply to any creditable service Any period of time in which a participating public employer pays an active member a salary and the active member or the employer on the member's behalf pays contributions to PERS.

One month of creditable service is earned for each major fraction of a month served. Creditable service includes all retirement credit received by a member. earned or prior service acquired by a member under the terms of a contract of integration made on or after October 1, 1991.
