“Agency,” as used in this Agreement, refers to the administrative body in each country responsible for taking and processing claims and making coverage determinations under each country’s social security laws.

The Social Security Administration (SSA) is the agency for the United States.  However, the U.S. Internal Revenue Service (IRS) retains its responsibility for determining Social Security tax liability based on SSA coverage determinations under this Agreement.  The Central Administration of National Pension Insurance (ONYF) and the National Health Insurance Fund (OEP) are the agencies for Hungary.
