A self-employed U.S. citizen who is subject only to Japanese law under the Agreement
            and is exempt from paying Social Security Self-Employment (SECA) tax must still file
            a U.S. tax return every year.
         
         To show that the self-employment earnings are exempt from U.S. Social Security self-employment
            tax, the person must do the following:
         
         • Indicate on Schedule SE that the earnings are exempt under the Agreement; and
         • Request a certificate of coverage from the Japanese authorities; and
         • Attach a photocopy of the certificate of coverage issued by Japan to the U.S. tax
            return every year as proof of the exemption.
