What Is a Transfer Pricing Case and Why Does It Matter to Your Business?

The Internal Revenue Code requires that intercompany transactions be priced using one of several specified methods: the comparable uncontrolled price method, the resale price method, the cost-plus method, the profit split method, or the transactional net margin method. Your transfer pricing position must be supported by contemporaneous documentation that demonstrates the method selected, the functional analysis of each party's role, economic analysis of comparable transactions, and the specific facts and circumstances that justify the pricing. The burden of proof generally rests on the taxpayer to establish that the chosen price falls within a reasonable range of arm's-length values. If the IRS successfully challenges your transfer price, the resulting adjustment can trigger not only additional tax liability but also accuracy-related penalties, and in cases of substantial misstatement, criminal referral risk in egregious circumstances.

Transfer pricing disputes have become a focal point for tax administrations worldwide because they represent a high-revenue area of potential tax avoidance. The OECD's Base Erosion and Profit Shifting (BEPS) initiative and subsequent guidance have intensified enforcement priorities around transfer pricing documentation, country-by-country reporting, and substance-over-form analysis. In practice, the IRS and state tax authorities examine whether the economic substance of the transaction supports the stated price, whether the taxpayer possessed contemporaneous documentation before the examination began, and whether the pricing methodology reflects genuine market conditions or instead appears designed primarily to shift income to low-tax jurisdictions.

A transfer pricing examination usually starts with an information document request (IDR) from the IRS or state tax authority asking for a description of the controlled transactions, the transfer pricing method applied, and supporting economic analysis. Your company must respond within a specified timeframe, often 30 days, with complete contemporaneous documentation. Delays or incomplete responses can trigger penalty exposure and weaken your negotiating position later. The examiner will review your documentation against the arm's-length standard, may engage economic experts to conduct comparability analysis, and will often request follow-up submissions if the initial documentation is deemed insufficient or if the examiner's analysis suggests the transfer price falls outside a defensible range.

When a transfer pricing adjustment proposed by the examining agent cannot be resolved through normal examination procedures, the case may proceed to the Appeals Office, which functions as an administrative case forum where both the IRS and the taxpayer present their positions to an independent appeals officer. The Appeals Office applies a hazards-of-litigation analysis, meaning it evaluates the relative strength of each party's legal and factual arguments and settles cases based on the probable outcome if the dispute were litigated. For transfer pricing matters, this stage offers an opportunity to present additional economic evidence, expert reports, and policy arguments without the formality of Tax Court. The appeals process can take one to three years depending on case complexity and docket congestion.

Deficient or missing contemporaneous documentation creates significant risk in a transfer pricing case. Under IRC Section 6662, substantial underpayment penalties apply if the transfer price adjustment exceeds the lesser of 10 percent of the correct tax or $5,000. If the IRS can demonstrate that your company lacked adequate contemporaneous documentation at the time the return was filed, the burden of proof may shift, requiring you to prove the transfer price was reasonable rather than requiring the IRS to prove it was unreasonable. In New York administrative practice, delayed submission of key economic analyses or functional descriptions can trigger procedural objections and limit your ability to introduce new theories or expert opinions during the appeals phase, making early documentation preparation essential.

The selection of transfer pricing method depends on the nature of the controlled transaction, the availability of comparable data, and the functions performed by each related party. The comparable uncontrolled price method is the most direct but requires reliable data on prices charged between unrelated parties in similar transactions. The cost-plus method adds a markup to the costs incurred by the supplier and is often used for manufacturing and service provision. The resale price method deducts a markup from the price charged to an unrelated customer and is common in distribution scenarios. The profit split method allocates combined profits based on each party's contribution and is used for highly integrated transactions or unique intangibles. Each method carries different evidentiary burdens and defensibility profiles depending on the facts. A company that selects a method without adequate economic justification or that applies a method inconsistently across years increases examination risk substantially.

Functional analysis documents the functions performed, assets employed, and risks assumed by each related party to the controlled transaction. The IRS requires detailed narratives describing who owns the intellectual property, who bears inventory risk, who provides management oversight, and who assumes credit risk. A credible functional analysis supports the transfer pricing method selected and demonstrates that the price allocation reflects genuine economic differences between the parties. Weak or boilerplate functional analysis, by contrast, signals to examiners that the pricing may be formulaic rather than economically grounded, increasing the likelihood of a detailed adjustment proposal. Courts and administrative tribunals give substantial weight to contemporaneous functional analysis that is detailed, transaction-specific, and updated annually to reflect changes in the business.

Maintain comprehensive, contemporaneous transfer pricing documentation that includes a detailed functional analysis, economic comparability study, and explicit identification of the transfer pricing method and arm's-length range. Conduct annual updates to your transfer pricing study to reflect changes in business operations, market conditions, and comparable data. Consider obtaining a transfer pricing opinion from an independent economic expert, which can strengthen your credibility with tax authorities and support your position in administrative proceedings. Ensure that your transfer pricing policy is applied consistently across all related-party transactions and across multiple years; inconsistent application invites examiner scrutiny and weakens your defense. Document the business rationale for the transfer pricing method selected.
