The term "WIN expenses" includes only salaries and wages paid or incurred in taxable years beginning after December 31, 1971. See paragraph (c) of § 1.50A-3 for rules relating to the determination of the first 12 months of employment (whether or not consecutive).
Example. X Company, which makes its return on the basis of the calendar year, hired WIN employees on January 1, 1972. X Company has a cost-plus construction contract with the Federal Government. The fact that X has a construction contract with the Federal Government or anyone else does not change its character from a normal business transaction in which there has been a sale of materials and services. Thus, the salaries or wages paid or incurred for services rendered by these WIN employees would not be reimbursed expenses, and X would be entitled to the credit provided by section 40.
Example. X Corporation, which files its return on the basis of the calendar year, hired A, a WIN employee, on January 1, 1972, and continuously employed him for the following 24-month period. During January and February of 1972, X paid A's wages while he received training conducted in Puerto Rico. For the remainder of the calendar year A performed services for X within the United States. For purposes of paragraph (a) of § 1.50A-3 and paragraph (a) of this section, A's first 12 months of employment are January 1, 1972, to December 31, 1972. Under subparagraph (1) of this paragraph no wages paid to A for services rendered during the months of January and February of 1972 may be taken into account by X under paragraph (a) of this section as WIN expenses because the services were rendered outside the United States. However, X may take into account wages he has incurred with respect to A for the period March 1, 1972, to December 31, 1972.
