Wages

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;

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;

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),

(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));

(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);

other than any such payment or series of payments which would have been paid if the employee’s employment relationship had not been so terminated;
