Understanding Social Security and Foreign Pensions: Key Rules and Exceptions
Verified against SSA POMS as of September 18, 2026
The short answer
Social Security benefits are affected by foreign pensions in specific ways. The Windfall Elimination Provision (WEP) may reduce benefits if you receive a foreign pension based on non-covered earnings post-1956. For benefits payable post-January 2024, the WEP no longer applies. Totalization agreements prevent WEP from applying if the foreign pension is based on an agreement with the U.S.
Effect of Foreign Pensions on Social Security
Foreign pensions can impact U.S. Social Security benefits through the Windfall Elimination Provision (WEP). The WEP applies to benefits payable for December 2023 and earlier when foreign pensions are based on non-covered earnings after 1956. There are exceptions, including when a pension comes from a country with a Totalization agreement, which allows for combining the U.S. and foreign credits to avoid WEP penalties. For details on WEP and foreign pensions, refer to GN 00307.291 and GN 00307.290.
GN 00307.291 View source ›Totalization Agreement Exemptions
Pensions based on Totalization agreements between the United States and foreign countries do not trigger WEP for months post-January 1995. Totalization agreements provide alternative eligibility criteria, allowing individuals to qualify under modified requirements. For example, under the U.S.-Swiss agreement, fewer years of Swiss coverage are needed for U.S. citizens residing outside Switzerland. Details are further explained in GN 01701.310.
GN 01701.310 View source ›Identifying Foreign Pensions Subject to WEP
Foreign pensions are categorized based on their origin. Those entirely based on residency or citizenship, such as Australia's Social Security, are not subject to WEP. However, a pension can trigger WEP if it is tied to non-covered work earnings post-1956 from a country without a Totalization agreement, as outlined in GN 00307.290.

For foreign pensions triggering WEP, documentation is required to verify pension amounts and covered periods. Acceptable proof includes award notifications or letters from the agency issuing the foreign pension. The document must be an original or certified photocopy. GN 01701.315 outlines the specific evidence required when a Totalization agreement is involved.

The calculation of the primary insurance amount (PIA) under the WEP involves prorating foreign pensions based on non-covered work. Only portions of the pension based on non-covered employment after 1956 are used. This involves converting weekly pension amounts to monthly amounts for computation as detailed in GN 00307.291.
