Generally, if you receive a government pension for work not covered by Social Security, your spouse’s or surviving spouse’s benefits will be reduced by the GPO.  If you receive such a pension, you would be exempt from the offset only if:

• Your last 60 months of employment were in a position covered under both Social Security and the government pension system (under certain conditions, fewer than 60 months may be required for people whose last day of employment falls between June 30, 2004, and March 2, 2009); or
• Your last day of employment was before July 1, 2004, and on the last day of employment you worked in a job covered under both Social Security and the government pension system; or
• You were entitled to and applied for the spouse’s or surviving spouse’s benefit before April 1, 2004, even if you did not retire until later.
