or a general committee of a railway-labor-organization employer, not conducting the principal part of its business in the United States, only when he is rendering service to it in the United States; and an individual shall be deemed to be in the service of such a local lodge or division only if (1) all, or substantially all, the individuals constituting its membership are employees of an employer conducting the principal part of its business in the United States; or (2) the headquarters of such local lodge or division is located in the United States; and an individual shall be deemed to be in the service of such a general committee only if (1) he is representing a local lodge or division described in clauses (1) or (2) immediately above; or (2) all, or substantially all, the individuals represented by it are employees of an employer conducting the principal part of its business in the United States; or (3) he acts in the capacity of a general chairman or an assistant general chairman of a general committee which represents individuals rendering service in the United States to an employer, but in such case if his office or headquarters is not located in the United States and the individuals represented by such general committee are employees of an employer not conducting the principal part of its business in the United States, only such proportion of the remuneration for such service shall be regarded as compensation as the proportion which the mileage in the United States under the jurisdiction of such general committee bears to the total mileage under its jurisdiction, unless such mileage formula is inapplicable, in which case such other formula as the Railroad Retirement Board may have prescribed pursuant to subsection (c) of section 1 of the Railroad Retirement Act of 1937 [50 Stat. 308; 45 U. S. C. 228a] shall be applicable, and if the application of such mileage formula, or such other formula as the Board may prescribe, would result in the compensation of the individual being less than 10 per centum of his remuneration for such service no part of such remuneration shall be regarded as compensation: Provided further, That an individual not a citizen or resident of the United States shall not be deemed to be in the service of an employer when rendering service outside the United States to an employer who is required under the laws applicable in the place where the service is rendered to employ therein, in whole or in part, citizens or residents thereof; and the laws applicable on August 29, 1935, in the place where the service, is rendered shall be deemed to have been applicable there at all times prior to that date.

Such term does not include tips, or the voluntary payment by an employer, without deduction from the remuneration of the employee, of the tax imposed on such employee by section 1500. Compensation which is earned during the period for which the Commissioner shall require a return of taxes under this subchapter to be made and which is payable during the calendar month following such period shall be deemed to have been paid during such period only. For the purpose of determining the amount of

taxes under sections 1500 and 1520, compensation earned in the service of a local lodge or division of a railway-labor-organization employer shall be disregarded with respect to any calendar month if the amount thereof is less than $3 * * *

A payment made by an employer to an individual through the employer's payroll shall be presumed, in the absence of evidence to the contrary, to be compensation for service rendered by such individual as an employee of the employer in the period with respect to which the payment is made. An employee shall be deemed to be paid "for time lost" the amount he is paid by an employer with respect to an identifiable period of absence from the active service of the employer, including absence on account of personal injury, and the amount he is paid by the employer for loss of earnings resulting from his displacement to a less remunerative position or occupation. If a payment is made by an employer with respect to a personal injury and includes pay for time lost, the total payment shall be deemed to be paid for time lost unless, at the time of payment, a part of such payment is specifically apportioned to factors other than time lost, in which event only such part of the payment as is not so apportioned shall be deemed to be paid for time lost.

[Section 1500 imposes a tax on the compensation, up to $300 a month, of employees of carriers.

Stat. 741) provides: "Sections 1500, 1510, and 1520 of the Internal Revenue Code as in effect on December 31, 1946, shall remain in full force and effect on and after January 1, 1947, with respect to any remuneration which constitutes compensation under the law as in effect on December 31, 1946, to which such sections as amended by this Act are not applicable."]
