The short version
When two companies under common ownership do business with each other, the price has to be the same one independent companies would have agreed to. That standard is called the arm's length principle. Transfer pricing is the work of setting those prices, supporting them with analysis, and documenting them so tax authorities accept the result.
What is transfer pricing?
Transfer pricing is the price charged on transactions between related parties, meaning companies that share common ownership or control. A U.S. parent that sells products to its foreign subsidiary, a software company that licenses its technology to an affiliate overseas, or a group that charges management fees between entities are all setting transfer prices.
These prices matter because they decide how much profit lands in each country, and therefore how much tax each country collects. Because a single group controls both sides of the deal, governments want assurance that the pricing reflects real economic value and is not just shifting profit to wherever taxes are lowest.
The arm's length principle
The arm's length principle is the foundation of transfer pricing. It says that a transaction between related companies should be priced as if it were between two unrelated companies negotiating in their own interest. If your subsidiary would pay a third party $100 for a part, it should pay your group the same kind of price.
In the United States this principle lives in Section 482 of the tax code, and around the world it is reflected in the OECD Transfer Pricing Guidelines. Most countries now have their own rules built on the same idea, which is why a group operating in several countries has to satisfy several sets of regulators at once.
Why it matters: the risks
Tax authorities have made transfer pricing a priority, and the reporting requirements that came out of the global Base Erosion and Profit Shifting (BEPS) project gave them far more visibility into how multinational groups operate. When a tax authority decides your pricing is not at arm's length, or that your documentation does not support it, the consequences add up quickly:
Double taxation is one of the most painful outcomes. If the U.S. raises the income of one entity but the other country does not lower the income of the related entity, the same dollar of profit gets taxed twice. Good planning and documentation are what keep you out of that situation.
Who needs to think about it?
Transfer pricing applies to any business with transactions between commonly owned entities. It is most visible in cross-border groups, but it can also reach domestic entities in certain situations. You should be paying attention if you have:
- A foreign parent, subsidiary, or sister company
- Intercompany sales of products or raw materials
- Shared services, management fees, or cost sharing between entities
- Licensing of intellectual property, software, or brands within the group
- Intercompany loans or financing arrangements
How a transfer pricing study works
Supporting your pricing starts with a functional analysis, which looks at what each entity actually does, what assets it uses, and what risks it carries. The entity that performs more valuable functions and carries more risk should earn more of the profit.
From there, a benchmarking study compares your intercompany pricing to what independent companies charge in similar deals, using the most appropriate method for the transaction. The analysis and conclusions go into a documentation report that your group keeps on hand, ready to show a tax authority if they ask. Preparing this documentation before you file, rather than after a notice arrives, is what protects you from penalties.
The main areas of transfer pricing work
A complete transfer pricing approach usually covers a few connected areas:
- Policy development. Designing intercompany pricing that fits how the business actually operates and meets its goals.
- Contemporaneous documentation. Preparing studies that satisfy IRC Section 482 and OECD guidelines and stand up to review.
- Operational transfer pricing. Putting the policy into practice and managing it through the year, not just at filing time.
- Advance Pricing Agreements (APAs). Negotiating agreements with a tax authority to lock in certainty on pricing for future years.
- Audit defense. Standing behind your position and managing exposure if a tax authority challenges it.
Rules differ by country and change often, and the right method depends on your specific facts. This article is general information, not tax advice. Talk with a qualified professional about your intercompany transactions before you file.
