            and contributions under the agreement and is exempt from paying Self-Employment Contributions

            earnings are exempt from U.S. Social Security self-employment tax, the individual
            must do the following:
         
         
            - 
               
                  • 
                     indicate on Schedule SE that the earnings are exempt under the agreement; 
 
 
- 
               
                  • 
                     request a certificate of coverage from the Icelandic authorities; and 
 
 
- 
               
                  • 
                     attach a photocopy of the Icelandic certificate of coverage to his or her U.S. tax
                        return every year (see RS 02002.550) as proof of the exemption.
