1. What transfer pricing actually is
Transfer pricing is the pricing of transactions between related parties — a U.S. subsidiary buying inventory from its Chinese parent, a U.S. company paying a related Shenzhen entity for engineering services, a brand license flowing across the Pacific. Under IRC Section 482, those prices must reflect what unrelated parties would have agreed to at arm's length. If they don't, the IRS can reallocate income between the entities — and China's tax authority applies the same principle from its side, which is how double taxation happens.
2. The scenarios we actually see at small multinationals
- Distribution: a Chinese manufacturer sells to its U.S. sales subsidiary. If the intercompany purchase price is set so high that the U.S. entity shows perpetual losses while selling successfully, that is the classic audit profile.
- Contract services / R&D: a U.S. startup pays a related Chinese team for development work. The Chinese entity typically deserves a routine cost-plus return; problems arise when it is paid a flat amount with no benchmark, or when it quietly ends up owning valuable IP.
- Management fees: parent charges the U.S. entity a "management fee" with no agreement, no description of services, and no support. Frequently disallowed on audit.
- Intercompany loans: funding the U.S. entity through open-ended, interest-free "loans" invites recharacterization; related-party loans need stated arm's length interest and documentation.
- IP and royalties: once the brand or technology has value, who owns it and what the royalty rate is becomes the highest-stakes question in the structure.
3. The methods, in plain language
The regulations prescribe methods and require the "best method" for your facts. In practice, small multinationals mostly use:
- Comparable Uncontrolled Price (CUP): the same product/service is sold to unrelated parties — use that price. Cleanest, rarely available.
- Cost plus: routine manufacturing or services earn cost plus a benchmarked markup. The workhorse for related-party service arrangements.
- Resale price: a distributor's gross margin is benchmarked against comparable distributors.
- Comparable Profits Method (CPM/TNMM): test the operating margin of the simpler entity against a set of comparable companies. This is what most small-multinational documentation is actually built on.
4. Documentation: your penalty insurance
Section 482 adjustments can carry accuracy-related penalties of 20%–40% under Section 6662(e) on large adjustments. The defense is contemporaneous documentation — a transfer pricing study that exists when the return is filed, identifying the transactions, the method chosen, and the comparables supporting your pricing. On the China side, entities above filing thresholds face their own Local File requirements and the related-party disclosure forms filed with the annual CIT return — the two sides need to tell the same story.
5. Don't forget the forms
Related-party flows are visible to the IRS by design: Form 5472 (foreign-owned U.S. entities) and Form 5471 (U.S. owners of foreign corporations) both require reporting of intercompany transactions, and customs values on imports should reconcile with the intercompany invoices. Filing the forms while having no support for the numbers on them is an audit invitation.
6. When to invest in a full study
A formal benchmarked study is worth it once intercompany flows become material relative to profits, when losses persist in one country, when IP or royalty flows begin, or before a financing round or acquisition where tax diligence will look. Before that point, the minimum discipline above — agreements, a defensible markup, and consistency — covers most of the risk at a fraction of the cost.
