OECD Model Article 15 Economic Employer Apportionment under Cross Border Assignments
Treaty relief under Article 15 collapses when the host entity directs daily work or absorbs compensation costs through recharged payroll.
Compensation Apportionment
Meaning
A financial allocation method divides employee remuneration expenses among different tax jurisdictions or corporate subsidiaries to reflect where the employment services were performed. Utilizing compensation apportionment prevents multi-national companies from over-allocating payroll costs to high-tax regions while ensuring compliance with local transfer pricing laws. This mechanism aligns corporate deductions with the actual location of value creation.
Allocation Methodology
Division of salary costs is typically based on the number of working days an employee spends in each territory during the fiscal year. Under compensation apportionment, equity-based compensation and bonuses are divided proportionally based on the vesting period or performance period spent in each country. This mathematical division guarantees that each subsidiary bears an accurate share of the overall payroll expense.
Transfer Pricing
Tax authorities demand that cross-border recharge of employment costs reflect arm-length principles to avoid artificial profit shifting. Proper documentation must support the apportionment to prevent double taxation of corporate profits.
Audit Risk
Multi-national enterprises face high exposure to tax audits if their cost-sharing arrangements lack consistency or documentation. If the compensation apportionment is found to be arbitrary, tax inspectors will disallow the corporate expense deductions in the host country, which leads to double taxation and penalties. These adjustments can trigger retrospective tax assessments and interest charges on unpaid corporate liabilities.
Companies must maintain contemporaneous logs of employee locations to substantiate their filings.
