Intercompany loan transactions are common within multinational corporate groups. However, determining the appropriate interest rate is one of the most sensitive aspects of Transfer Pricing and has become an increasing focus of tax authorities.
An interest rate that lacks adequate economic support may result in tax adjustments, limitations on interest deductibility, and penalties. Conversely, a well-documented pricing policy strengthens the taxpayer’s position, reduces audit risks, and provides greater certainty for cross-border financing transactions.
Although both Brazil and the United States follow the arm’s length principle, the methods used to demonstrate that an interest rate reflects market conditions differ significantly.
United States: The AFR as a Reference, But Not Necessarily a Market Rate
In the United States, the Internal Revenue Service (IRS) publishes the Applicable Federal Rate (AFR) each month. The AFR serves as a minimum benchmark for certain related-party transactions, particularly under the rules established by Section 7872 of the Internal Revenue Code.
In addition, Section 482 provides standards that, under certain circumstances, reduce the likelihood of IRS challenges when the interest rate falls within a range associated with the AFR.
However, the AFR does not always reflect the rate that unrelated parties would negotiate. In transactions involving higher credit risk, unsecured financing, or bullet-payment structures, an independent lender would generally require a higher return.
In these cases, preparing a benchmark study in accordance with Treasury Regulation §1.482-2(a) becomes essential to demonstrate, based on market data, that the interest rate satisfies the arm’s length principle.
Brazil: New Rules Require Documentation Based on Comparable Transactions
With the enactment of Law No. 14,596/2023, Brazil adopted the OECD Transfer Pricing Guidelines, replacing its former system based on predetermined statutory parameters.
Normative Instruction RFB No. 2,161/2023 regulates financial transactions between related parties, including intercompany loans, cash pooling arrangements, and guarantees, without establishing any interest rate that is automatically accepted by the Brazilian Federal Revenue Service.
In practice, determining an arm’s length interest rate requires consideration of several factors, including:
- The borrower’s credit risk profile, generally assessed on a standalone basis, with a specific evaluation of any implicit group support;
- The characteristics of the transaction, including maturity, currency, collateral, and repayment terms; and
- Comparable transactions identified through recognized financial databases such as Bloomberg or Capital IQ.
Under this new framework, documentation supported by comparable market data is no longer simply a tool for justifying higher interest rates. It has become a fundamental component of Transfer Pricing compliance.
Key Differences Between Brazil and the United States
| Aspect | United States | Brazil |
|---|---|---|
| Minimum Reference | AFR for certain situations | No predefined acceptable interest rate |
| Demonstrating an Arm’s Length Rate | Benchmark study when supporting a rate different from the AFR | Benchmark study required to demonstrate compliance with the arm’s length principle |
| Credit Analysis | May consider implicit group support | Primarily standalone analysis, with specific consideration of potential implicit group support |
| Legal Framework | Internal Revenue Code Sections 482 and 7872 | Law No. 14,596/2023 and Normative Instruction RFB No. 2,161/2023 |
Considerations for Multinational Groups
Companies conducting intercompany financing transactions between Brazil and the United States should evaluate each loan agreement under the applicable rules of both jurisdictions.
Although both countries apply the arm’s length principle, the requirements for demonstrating that an interest rate is consistent with market conditions are not identical. A benchmark study prepared solely to satisfy IRS requirements may not fully comply with Brazilian regulations, just as documentation prepared for Brazil may not satisfy all U.S. requirements.
A comprehensive analysis involves more than selecting an interest rate. It should also assess the borrower’s creditworthiness, the transaction’s terms, the existence of collateral, the financing period, and the economic evidence supporting the agreed-upon pricing.
