As used in this subsection, the term “pay period” means a period (of not more than 31 consecutive days) for which a payment of remuneration is ordinarily made to the employee by the person employing him.

For the purpose of the computation to the nearest dollar, the payment of a fractional part of a dollar shall be disregarded unless it amounts to one-half dollar or more, in which case it shall be increased to $1. The amount of any payment of cash remuneration so computed to the nearest dollar shall, in lieu of the amount actually paid, be deemed to constitute the amount of cash remuneration for purposes of subsection (a)(7)(B).

Regulations of the Secretary to carry out the purposes of this subsection shall be designed to make the requirements imposed on American employers with respect to services covered by an agreement entered into pursuant to this subsection the same, so far as practicable, as those imposed upon employers pursuant to this title with respect to the taxes imposed by this chapter.

For purposes of this chapter and chapter 2, a crew leader shall, with respect to service performed in furnishing individuals to perform agricultural labor for another person and service performed as a member of the crew, be deemed not to be an employee of such other person.

For purposes of this subsection, a member of a religious order means any individual who is subject to a vow of poverty as a member of such order and who performs tasks usually required (and to the extent usually required) of an active member of such order and who is not considered retired because of old age or total disability.

Any church or qualified church-controlled organization (as defined in paragraph (3)) may make an election within the time period described in paragraph (2), in accordance with such procedures as the Secretary determines to be appropriate, that services performed in the employ of such church or organization shall be excluded from employment for purposes of title II of the Social Security Act and this chapter. An election may be made under this subsection only if the church or qualified church-controlled organization states that such church or organization is opposed for religious reasons to the payment of the tax imposed under section 3111.
An election under this subsection must be made prior to the first date, more than 90 days after July 18, 1984, on which a quarterly employment tax return for the tax imposed under section 3111 is due, or would be due but for the election, from such church or organization. An election under this subsection shall apply to current and future employees, and shall apply to service performed after December 31, 1983. The election may be revoked by the church or organization under regulations prescribed by the Secretary. The election shall be revoked by the Secretary if such church or organization fails to furnish the information required under section 6051 to the Secretary for a period of 2 years or more with respect to remuneration paid for such services by such church or organization, and, upon request by the Secretary, fails to furnish all such previously unfurnished information for the period covered by the election. Any revocation under the preceding sentence shall apply retroactively to the beginning of the 2-year period for which the information was not furnished.
For purposes of subsection (a)(7)(B), the term “applicable dollar threshold” means $1,000. In the case of calendar years after 1995, the Commissioner of Social Security shall adjust such $1,000 amount at the same time and in the same manner as under section 215(a)(1)(B)(ii) of the Social Security Act with respect to the amounts referred to in section 215(a)(1)(B)(i) of such Act, except that, for purposes of this paragraph, 1993 shall be substituted for the calendar year referred to in section 215(a)(1)(B)(ii)(II) of such Act. If any amount as adjusted under the preceding sentence is not a multiple of $100, such amount shall be rounded to the next lowest multiple of $100.
If any employee of a foreign person is performing services in connection with a contract between the United States Government (or any instrumentality thereof) and any member of any domestically controlled group of entities which includes such foreign person, such foreign person shall be treated for purposes of this chapter as an American employer with respect to such services performed by such employee.
The term “domestically controlled group of entities” means a controlled group of entities the common parent of which is a domestic corporation.
In the case of a foreign person who is a member of any domestically controlled group of entities, the common parent of such group shall be jointly and severally liable for any tax under this chapter for which such foreign person is liable by reason of this subsection, and for any penalty imposed on such person by this title with respect to any failure to pay such tax or to file any return or statement with respect to such tax or wages subject to such tax. No deduction shall be allowed under this title for any liability imposed by the preceding sentence.
Paragraph (1) shall not apply to any services which are covered by an agreement under subsection (l).
Paragraph (1) shall not apply to any services if the employer establishes to the satisfaction of the Secretary that the remuneration paid by such employer for such services is subject to a tax imposed by a foreign country which is substantially equivalent to the taxes imposed by this chapter.
