Transfer Pricing Under Section 482: A Method Decision Guide

Every transaction between your U.S. entity and a foreign subsidiary needs a price that an unrelated party would have agreed to under similar circumstances, whether that's a management fee for headquarters support, a royalty for shared intellectual property, or interest on an intercompany loan. Get the pricing wrong, even without any intent to shift income to a lower-tax jurisdiction, and the IRS can adjust it unilaterally on audit, which usually means additional tax in the U.S. entity plus penalties, without a corresponding adjustment on the foreign side unless a treaty mechanism resolves the resulting double taxation.

The resale price method works backward from the price the subsidiary charges to an unrelated customer, subtracting an appropriate gross margin to arrive at what the intercompany price should have been, benchmarked against the margins unrelated distributors earn in comparable businesses. The cost plus method runs the other direction, starting from the cost of providing goods or services and adding a markup benchmarked the same way. Both methods depend on finding genuinely comparable companies and comparable gross margins; software distribution and services comparables, for instance, often run gross margins other sectors don't¹, so the comparable set you choose has to match your subsidiary's actual function, not just its industry label.

Resale price and cost plus both assume one side of the transaction is the routine party, performing a standard function that a market benchmark can price, while the other side holds the unique value, usually the intellectual property or the customer relationships. When both the parent and the subsidiary contribute something genuinely unique, joint development of core technology, for example, a profit split method that divides combined profit based on each entity's relative contribution often fits better than forcing a one-sided comparison that doesn't reflect how the value was actually created.

A lot of transfer pricing exposure for a smaller company doesn't come from IP licensing at all; it comes from underpriced or unpriced intercompany services, a parent company's finance, HR, or engineering staff supporting a foreign subsidiary without a documented services agreement or a defensible fee. Getting a handle on what those services actually cost, and what an unrelated provider would charge for them, usually starts with clean compensation and cost data across both entities. A global payroll platform such as Deel, if that's how you're already paying staff across borders, can make it far easier to pull the actual cost data a transfer pricing study needs instead of reconstructing it after the fact.

Contemporaneous documentation, meaning a transfer pricing study prepared around the time the pricing was set rather than reconstructed after an audit notice arrives, is what separates a defensible position from a vulnerable one. That documentation should identify the method chosen and why it fits the transaction, the comparable companies or transactions used to benchmark it, and how the pricing was actually applied in practice, not just in theory. A study built after the fact, once an examiner has already asked the question, carries far less weight than one that existed before the transaction happened. Revisit the study whenever the underlying facts change too, a subsidiary taking on a new function, a shift in who actually bears the business risk, since a study that accurately described the arrangement two years ago can become stale evidence rather than support once the arrangement itself has quietly evolved.

A defensible transfer pricing file typically shows:

• The method you chose and why it fits the specific transaction, whether resale price, cost plus, or profit split.
• The comparable companies or transactions used to benchmark the intercompany price.
• A study prepared around the time the pricing was set, not reconstructed after an audit notice arrives.
• A written services agreement and a defensible fee for any intercompany services, such as finance, HR or engineering support for the subsidiary.
