Agreement with respect to certain employees of foreign affiliate

The Secretary shall, at the American employer’s request, enter into an agreement (in such manner and form as may be prescribed by the Secretary) with any American employer (as defined in subsection (h)) who desires to have the insurance system established by title II of the Social Security Act extended to service performed outside the United States in the employ of any 1 or more of such employer’s foreign affiliates (as defined in paragraph (6)) by all employees who are citizens or residents of the United States, except that the agreement shall not apply to any service performed by, or remuneration paid to, an employee if such service or remuneration would be excluded from the term “employment” or “wages”, as defined in this section, had the service been performed in the United States. Such agreement may be amended at any time so as to be made applicable, in the same manner and under the same conditions, with respect to any other foreign affiliate of such American employer. Such agreement shall be applicable with respect to citizens or residents of the United States who, on or after the effective date of the agreement, are employees of and perform services outside the United States for any foreign affiliate specified in the agreement. Such agreement shall provide—

(A) that the American employer shall pay to the Secretary, at such time or times as the Secretary may by regulations prescribe, amounts equivalent to the sum of the taxes which would be imposed by sections 3101 and 3111 (including amounts equivalent to the interest, additions to the taxes, additional amounts, and penalties which would be applicable) with respect to the remuneration which would be wages if the services covered by the agreement constituted employment as defined in this section; and

(B) that the American employer will comply with such regulations relating to payments and reports as the Secretary may prescribe to carry out the purposes of this subsection.
