Plain English
This is America's version of Article 9 — the legal basis the IRS uses to challenge intercompany pricing. It is older and more prescriptive than the OECD framework in places, with detailed Treasury Regulations covering the best-method rule, specific methods, and a controversial 'commensurate with income' standard for intangibles. Any US multinational, or foreign group with a US subsidiary, lives under this statute.
Technical definition
Section 482 of the Internal Revenue Code empowers the Secretary of the Treasury to distribute, apportion, or allocate gross income, deductions, credits, or allowances between two or more organizations, trades, or businesses owned or controlled directly or indirectly by the same interests, where necessary to prevent evasion of taxes or clearly to reflect income, applied through the Treasury Regulations at 26 CFR 1.482 which mandate the arm's length standard and a 'best method rule' rather than a strict method hierarchy.
Why it matters
It is the largest single body of binding transfer pricing law in the world by dollar value of adjustments and litigation, shaping global practice on intangibles (the 'commensurate with income' standard) and cost sharing arrangements even outside the US.
How it works in practice
- 01Identify controlled transactions between the US entity and foreign related parties.
- 02Apply the best method rule: select whichever specified method most reliably measures an arm's length result, rather than following a fixed hierarchy.
- 03For intangibles, apply the commensurate-with-income standard, which can require periodic adjustments as profitability changes.
- 04Prepare contemporaneous documentation under Treas. Reg. 1.6662-6 to secure penalty protection.
- 05Defend positions through IRS exam, Advance Pricing Agreements, or litigation in Tax Court.
Worked example
Cost sharing arrangement and buy-in payment
A US technology parent enters a cost sharing arrangement with its Irish subsidiary to jointly develop software IP, with Ireland taking on future European exploitation rights. Section 482 regulations require Ireland to make a 'buy-in' payment reflecting the value of pre-existing US-developed technology and reasonably anticipated benefits, valued at roughly $300m based on discounted cash flow projections. If actual profits in Ireland later far exceed those projections, the commensurate-with-income standard allows the IRS to argue the buy-in payment was understated and seek a periodic adjustment.
Common mistakes
- Assuming the OECD five-method hierarchy applies identically under US rules, when the best-method rule instead requires the most reliable method regardless of a preferred order.
- Missing the higher documentation bar the US penalty regime effectively imposes for penalty protection under Section 6662(e).
- Underestimating IRS scrutiny of cost sharing buy-in and platform contribution valuations.
Audit red flags
- No contemporaneous Section 6662(e) documentation despite material intercompany transactions.
- Cost sharing arrangements with buy-in payments unsupported by a documented valuation.
- Persistent losses in the US entity of an inbound multinational group.
Documentation & data
Documents to hold
- Contemporaneous transfer pricing study meeting the specific requirements of Treas. Reg. 1.6662-6(d).
- Cost sharing agreement and buy-in/PCT valuation memos where applicable.
- Functional and comparability analysis supporting the best method selected.
Data you need
- US and foreign related-party transaction data reconciled to Form 5471/5472 filings.
- Comparable company data, typically from US-focused databases.
- Cost sharing platform valuation inputs where relevant.
Who owns this internally: US tax counsel and transfer pricing specialists, coordinated with global tax on cross-border consistency.
Jurisdiction notes
- United States
- Governed entirely by Section 482 and Treas. Reg. 1.482, independent of the OECD Guidelines, though outcomes are usually similar.
- Inbound investors
- Foreign parents with US distribution subsidiaries face particular IRS scrutiny given persistent historical loss patterns in some US importer structures.
Notes by role
In-house tax teams
If you have any US entity, build Section 6662(e) documentation timing into your compliance calendar separately from OECD-style master/local file deadlines.
CFOs & finance leaders
Section 482 penalties can reach 20-40% of the understatement on top of the tax itself — contemporaneous documentation is cheap insurance against that.
Frequently asked
- Does Section 482 use the same five methods as the OECD Guidelines?
- The specified methods are very similar in substance, but Section 482 applies a best-method rule instead of a hierarchy, and adds specific rules like the commensurate-with-income standard for intangibles.
- What is the practical effect of 'commensurate with income'?
- It allows the IRS to require periodic adjustments to intangible transfer pricing if actual profits diverge substantially from what was projected at the time of the original pricing.
