The arm’s length principle is the foundation of U.S. transfer pricing rules. It answers one simple question:
If these two companies were not related, what price would they have agreed to?
In other words, Related companies should charge prices similar to those agreed upon by independent businesses when they buy or sell goods, provide services, license intellectual property, or make loans.
The arm’s length principle is the cornerstone of Internal Revenue Code (IRC) Section 482 and the Treasury Regulations issued under it. Under this law, the IRS expects related companies to price their transactions as though they were independent businesses dealing with each other in the open market. If the prices do not reflect what unrelated parties would have agreed to under similar circumstances, the IRS may adjust the company’s income or deductions to ensure that taxable income is reported correctly.
Next, let’s understand why the arm’s length principle is important for transfer pricing.
Why Is the Arm’s Length Principle Important?
Generally, related companies are under common ownership. Therefore, they can decide the prices they charge each other. Without transfer pricing rules, a business could charge unusually high or low prices to move profits from one country to another and reduce its overall tax liability.
The arm’s length principle helps prevent this by requiring related companies to price their transactions as though they were independent businesses negotiating in the open market. The objective is to ensure that each company reports an appropriate amount of profit in the country where it performs its business activities and creates value.
Let’s understand the concept of the arm’s length principle through a simple example.
For example, suppose a U.S. company hires an independent consulting firm to provide management services. After comparing several firms, it agrees to pay $100,000.
Now suppose the U.S. company instead receives the same services from its related company in Canada. The fee charged should generally be similar to what an independent consulting firm would have charged for comparable services.
For example, suppose a U.S. company hires an independent consulting firm to provide management services. After comparing several firms, it agrees to pay $100,000 for the work.
Now suppose the U.S. company instead gets the same services from its related company in Canada. Under the arm’s-length principle, the fee should still be around what an independent firm would charge, which is about $100,000.
Suppose the Canadian affiliate charges $300,000 instead, with no valid business reason for the higher fee. That extra $200,000 is now a deductible expense for the U.S. company, which lowers its U.S. taxable income by $200,000. At the same time, the Canadian affiliate’s income goes up by $200,000. In effect, $200,000 of taxable profit has moved from the U.S. to Canada.
Fee Comparison
| Arm’s-Length Fee | Actual Fee Charged | |
| Fee paid | $100,000 | $300,000 |
| Reduction in U.S. taxable income | $0 | $200,000 |
| Increase in Canadian income | $0 | $200,000 |
If the IRS determines that $300,000 doesn’t reflect an arm’s-length price, it can adjust the U.S. company’s taxable income back up under IRC Section 482 — treating the deal as if only $100,000 had been paid.
Next, let’s understand how the IRS determines the arm’s length pricing of transactions.
How Does the IRS Determine Whether a Price Is Arm’s Length?
Determining an arm’s length price involves more than comparing numbers. The IRS looks at the facts and circumstances of the transaction to understand whether the pricing reflects economic reality.
The IRS generally follows four key steps to arrive at an arm’s-length price. The following is a brief overview of these steps. For detailed information, please see the article at the link below.
1. Identify the Controlled Transaction
This step involves identifying the controlled transaction between the related parties. A controlled transaction is basically the transaction between related parties that needs to be analyzed. This means analyzing what is being transferred, such as products, services, intellectual property, or financing.
2. Perform a functional analysis
The next step is called performing a functional analysis. A functional analysis is determining what each company contributes by examining the functions it performs, the assets it uses, and the risks it assumes. This helps identify where value is created within the business group.
3. Select the most appropriate transfer pricing method
After understanding the transaction, the next step is to decide how to determine an arm’s-length price. This is determined through several methods set forth in the Treasury Regulations.
U.S. transfer pricing rules require businesses to choose the method that provides the most reliable result based on the facts of the transaction.
This is known as the Best Method Rule.
4. Compare the results with Market Data
Whenever possible, businesses compare their transaction with similar transactions between unrelated companies. This process, known as benchmarking, helps demonstrate that the transfer price is consistent with market conditions.
Simply understanding the arm’s length principle is not enough. Businesses should be able to show that the prices charged between related companies reflect market conditions. They do this by carrying out a structured transfer pricing analysis that reviews the transaction, the role of each company, and comparable market data. This process helps determine whether the transaction meets the arm’s length standard required under U.S. tax law.
Next, let’s understand how businesses determine an arm’s length price by following the step-by-step transfer pricing analysis required under U.S. tax law.
