Payroll-Cost Sourcing Explained
Corp X, a domestic corporation, receives $150,000 under a contract for services performed concurrently in the United States and in several foreign countries by numerous Corp X employees. Each employee performs services exclusively in one jurisdiction, and the compensation must be sourced between U.S. and foreign labor under Treas. Reg. § 1.861-4(b)(1)(ii).
Although the number of employees — and the hours they spend — performing the contract within the United States equals the number performing it abroad (250 hours, or 50% of time, on each side), the U.S. employees are paid more because of the more sophisticated nature of the services they perform. The U.S. payroll cost for the contract is $20,000 out of a total contract payroll cost of $30,000, while the foreign payroll cost is $10,000.
Under these facts, a determination based upon relative payroll costs — rather than time — is the basis that most correctly reflects the proper source of the income. Accordingly, of the $150,000 included in Corp X's gross income, $100,000 ($150,000 × $20,000/$30,000) is attributable to labor performed within the United States and $50,000 ($150,000 × $10,000/$30,000) is attributable to labor performed without the United States.
