compensation
(1) The term “compensation” means any form of money remuneration paid to an individual for services rendered as an employee to one or more employers or as an employee representative, including remuneration paid for time lost as an employee, but remuneration paid for time lost shall be deemed earned in the month in which such time is lost. 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. Compensation earned in any calendar month before 1947 shall be deemed paid in such month regardless of whether or when payment will have been in fact made, and compensation earned in any calendar year after 1946 but paid after the end of such calendar year shall be deemed to be compensation paid in the calendar year in which it will have been earned if it is so reported by the employer before February 1 of the next succeeding calendar year or if the employee establishes, subject to the provisions of section 231h of this title , the period during which such compensation will have been earned.
