    Sec. 3121. Definitions
 
    (a) Wages
      For purposes of this chapter, the term ''wages'' means all
    remuneration for employment, including the cash value of all
    remuneration (including benefits) paid in any medium other than
    cash; except that such term shall not include -
        (1) in the case of the taxes imposed by sections 3101(a) and
      3111(a) that part of the remuneration which, after remuneration
      (other than remuneration referred to in the succeeding paragraphs
      of this subsection) equal to the contribution and benefit base
      (as determined under section 230 of the Social Security Act) with
      respect to employment has been paid to an individual by an
      employer during the calendar year with respect to which such
      contribution and benefit base is effective, is paid to such
      individual by such employer during such calendar year.  If an
      employer (hereinafter referred to as successor employer) during
      any calendar year acquires substantially all the property used in
      a trade or business of another employer (hereinafter referred to
      as a predecessor), or used in a separate unit of a trade or
      business of a predecessor, and immediately after the acquisition
      employs in his trade or business an individual who immediately
      prior to the acquisition was employed in the trade or business of
      such predecessor, then, for the purpose of determining whether
      the successor employer has paid remuneration (other than
      remuneration referred to in the succeeding paragraphs of this
      subsection) with respect to employment equal to the contribution
      and benefit base (as determined under section 230 of the Social
      Security Act) to such individual during such calendar year, any
      remuneration (other than remuneration referred to in the
      succeeding paragraphs of this subsection) with respect to
      employment paid (or considered under this paragraph as having
      been paid) to such individual by such predecessor during such
      calendar year and prior to such acquisition shall be considered
      as having been paid by such successor employer;
        (2) the amount of any payment (including any amount paid by an
      employer for insurance or annuities, or into a fund, to provide
      for any such payment) made to, or on behalf of, an employee or
      any of his dependents under a plan or system established by an
      employer which makes provision for his employees generally (or
      for his employees generally and their dependents) or for a class
      or classes of his employees (or for a class or classes of his
      employees and their dependents), on account of -
          (A) sickness or accident disability (but, in the case of
        payments made to an employee or any of his dependents, this
        subparagraph shall exclude from the term ''wages'' only
        payments which are received under a workman's compensation
        law), or
          (B) medical or hospitalization expenses in connection with
        sickness or accident disability, or
          (C) death, except that this paragraph does not apply to a
        payment for group-term life insurance to the extent that such
        payment is includible in the gross income of the employee;
        ((3) Repealed. Pub. L. 98-21, title III, Sec. 324(a)(3)(B),
      Apr. 20, 1983, 97 Stat. 123)
        (4) any payment on account of sickness or accident disability,
      or medical or hospitalization expenses in connection with
      sickness or accident disability, made by an employer to, or on
      behalf of, an employee after the expiration of 6 calendar months
      following the last calendar month in which the employee worked
      for such employer;
        (5) any payment made to, or on behalf of, an employee or his
      beneficiary -
          (A) from or to a trust described in section 401(a) which is
        exempt from tax under section 501(a) at the time of such
        payment unless such payment is made to an employee of the trust
        as remuneration for services rendered as such employee and not
        as a beneficiary of the trust,
          (B) under or to an annuity plan which, at the time of such
        payment, is a plan described in section 403(a),
          (C) under a simplified employee pension (as defined in
        section 408(k)(1)), other than any contributions described in
        section 408(k)(6),
          (D) under or to an annuity contract described in section
        403(b), other than a payment for the purchase of such contract
        which is made by reason of a salary reduction agreement
        (whether evidenced by a written instrument or otherwise),
          (E) under or to an exempt governmental deferred compensation
        plan (as defined in subsection (v)(3)),
          (F) to supplement pension benefits under a plan or trust
        described in any of the foregoing provisions of this paragraph
        to take into account some portion or all of the increase in the
        cost of living (as determined by the Secretary of Labor) since
        retirement but only if such supplemental payments are under a
        plan which is treated as a welfare plan under section
        3(2)(B)(ii) of the Employee Retirement Income Security Act of
        1974,
          (G) under a cafeteria plan (within the meaning of section
        125) if such payment would not be treated as wages without
        regard to such plan and it is reasonable to believe that (if
        section 125 applied for purposes of this section) section 125
        would not treat any wages as constructively received,
          (H) under an arrangement to which section 408(p) applies,
        other than any elective contributions under paragraph (2)(A)(i)
        thereof, or
          (I) under a plan described in section 457(e)(11)(A)(ii) and
        maintained by an eligible employer (as defined in section
        457(e)(1));
        (6) the payment by an employer (without deduction from the
      remuneration of the employee) -

        or
          (B) of any payment required from an employee under a State
        unemployment compensation law,
      with respect to remuneration paid to an employee for domestic
      service in a private home of the employer or for agricultural
      labor;
        (7)(A) remuneration paid in any medium other than cash to an
      employee for service not in the course of the employer's trade or
      business or for domestic service in a private home of the
      employer;
        (B) cash remuneration paid by an employer in any calendar year
      to an employee for domestic service in a private home of the
      employer (including domestic service on a farm operated for profit),
      if the cash remuneration paid in such year by the
      employer to the employee for such service is less than the
      applicable dollar threshold (as defined in subsection (x)) for
      such year;
        (C) cash remuneration paid by an employer in any calendar year
      to an employee for service not in the course of the employer's
      trade or business, if the cash remuneration paid in such year by
      the employer to the employee for such service is less than $100.
      As used in this subparagraph, the term ''service not in the
      course of the employer's trade or business'' does not include
      domestic service in a private home of the employer and does not
      include service described in subsection (g)(5);
        (8)(A) remuneration paid in any medium other than cash for
      agricultural labor;

          (i) the cash remuneration paid in such year by the employer
        to the employee for such labor is $150 or more, or
          (ii) the employer's expenditures for agricultural labor in
        such year equal or exceed $2,500,
      except that clause (ii) shall not apply in determining whether
      remuneration paid to an employee constitutes ''wages'' under this
      section if such employee (I) is employed as a hand harvest
      laborer and is paid on a piece rate basis in an operation which
      has been, and is customarily and generally recognized as having
      been, paid on a piece rate basis in the region of employment,
      (II) commutes daily from his permanent residence to the farm on
      which he is so employed, and (III) has been employed in
      agriculture less than 13 weeks during the preceding calendar
      year;
        ((9) Repealed. Pub. L. 98-21, title III, Sec. 324(a)(3)(B),

          (B) under a plan established by the employer which makes
        provision for his employees generally or a class or classes of

      legal services plans);
        (18) any payment made, or benefit furnished, to or for the

              423(b)), or
           (B) any disposition by the individual of such stock.
     
    Nothing in the regulations prescribed for purposes of chapter 24
    (relating to income tax withholding) which provides an exclusion
    from ''wages'' as used in such chapter shall be construed to
    require a similar exclusion from ''wages'' in the regulations
    prescribed for purposes of this chapter.  Except as otherwise
    provided in regulations prescribed by the Secretary, any third
    party which makes a payment included in wages solely by reason of
    the parenthetical matter contained in subparagraph (A) of paragraph
    (2) shall be treated for purposes of this chapter and chapter 22 as
    the employer with respect to such wages.

    service, of whatever nature, performed (A) by an employee for the
    person employing him, irrespective of the citizenship or residence
    of either, (i) within the United States, or (ii) on or in

    States as an employee for an American employer (as defined in

    whom performed, which is designated as employment or recognized as
    equivalent to employment under an agreement entered into under
    section 233 of the Social Security Act; except that such term shall
    not include -
        (1) service performed by foreign agricultural workers lawfully

        least 4 continuous weeks in the calendar quarter in which the
        service is rendered, and
          (ii) a son, daughter, stepson, or stepdaughter of such
        employer is living in the home, and

      State or political subdivision prior to 1951 and, at the time of
      its first acquisition (after 1950) from private ownership of any
      part of its transportation system, the State or political
      subdivision did not have a general retirement system covering
      substantially all service performed in connection with the

        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

      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

        such time or times as the Secretary may by regulations
        prescribe, amounts equivalent to the sum of the taxes which

        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.
      (2) Effective period of agreement
        An agreement entered into pursuant to paragraph (1) shall be in
      effect for the period beginning with the first day of the

      in the agreement; except that in case such agreement is amended
      to include the services performed for any other affiliate and
      such amendment is executed after the first month following the
      first calendar quarter for which the agreement is in effect, the
      agreement shall be in effect with respect to service performed
      for such other affiliate only after the calendar quarter in which
      such amendment is executed.  Notwithstanding any other provision
      of this subsection, the period for which any such agreement is
      effective with respect to any foreign entity shall terminate at

        pursuant to paragraph (1) as would be wages if the services
        constituted employment, and
          (B) as is reported to the Secretary pursuant to the
        provisions of such agreement or of the regulations issued under
        this subsection,
      shall be considered wages subject to the taxes imposed by this

      respect to the amounts due under such agreement shall be made,
      without interest, in such manner and at such times as may be
      required by regulations prescribed by the Secretary.
        (B) If an overpayment cannot be adjusted under subparagraph
      (A), the amount thereof shall be paid by the Secretary, through
      the Fiscal Service of the Treasury Department, but only if a
      claim for such overpayment is filed with the Secretary within two

      employing individuals on its own account.
      (8) Regulations

    other provision of such Code) for repayment of any taxes which it

    performed service for which remuneration was paid before July 30,
    1965, by an organization which, before such date, filed a waiver
    certificate pursuant to subsec. (k)(1) of this section, then under
    certain conditions, the remuneration paid with respect to such
    service was to be deemed remuneration for employment for purposes
    of title II of the Social Security Act, sections 401 et seq, of
    Title 42, The Public Health and Welfare, even though normally
    excluded from employment under title II of the Social Security Act.

    1950 with respect to which remuneration was paid before 1960 and
    such service is normally excepted from employment under title II of
    the Social Security Act (42 U.S.C. 401 et seq.), then under certain

    period of employment a valid waiver certificate, or, which failed
    to have the individual's signature appear on the list of signatures
    of employees who concurred in the filing of such certificate, where
