In many ways, intercompany loans work like bank loans. One entity becomes the lender, the other the borrower, and the borrower must repay the principal plus interest. The key difference is that the transaction happens within the group rather than with an external bank. That internal nature does not make it informal. Companies still need formal agreements, clear terms comparable to market standards, and proper accounting treatment. 

Why do tax authorities care about intercompany loans? 

Interest on intercompany loans affects where profits are reported. The borrowing entity records interest as an expense, reducing taxable income, while the lending entity records interest as income. This can shift profits from high-tax countries to low-tax countries. 

Cross-border loans therefore attract particular attention from tax authorities. Governments have introduced rules based on the arm’s length principle, which requires that intercompany loans be priced and structured as if the parties were unrelated. Interest rates, terms, and conditions must reflect real market conditions. 

If loans are poorly documented, unrealistic, or structured mainly for tax purposes, they can trigger audits, adjustments, penalties, and reputational risk. 

What are transfer pricing rules and compliance considerations? 

Intercompany loans fall under transfer pricing rules for financial transactions. These rules require companies to treat intra-group loans like third-party financing. 

Key compliance considerations include: 

Market-based interest rates
Interest must be determined using comparable market data and aligned with what an independent lender would charge. 

Borrower credit risk
The borrower’s ability to repay must be assessed, often using a stand-alone credit rating and adjustments for group support. 

Realistic loan terms
Terms such as currency, maturity, repayment schedule, collateral, and default provisions should reflect commercial reality. 

Documentation requirements
Companies must maintain formal loan agreements, transfer pricing documentation, and supporting analyses. 

Additional compliance analyses
Depending on the jurisdiction, companies may also need to perform debt capacity analyses, credit rating studies, and cash pool synergy allocation following OECD guidance. 

Tax authorities increasingly examine whether the loan has a clear business rationale and whether the borrower could realistically obtain similar financing from a third party. 

What are common intercompany loan mistakes companies make? 

Despite their importance, intercompany loans are often treated as low-risk internal transactions.
