What Is Transfer Pricing?

When two related companies in different countries transact with each other — whether selling goods, providing services, licensing intellectual property, or lending money — the prices they charge each other are known as transfer prices.

Unlike transactions between unrelated parties, these internal prices could theoretically be set at any level. This creates an obvious opportunity: a business could shift profits from a high-tax country to a low-tax country simply by manipulating its internal pricing. Tax authorities around the world are acutely aware of this, which is why transfer pricing regulations are among the most scrutinized areas of international tax law.

The Arm's Length Principle

The foundation of transfer pricing compliance globally is the arm's length principle. This principle requires that transactions between related parties be priced as if they were conducted between independent parties in comparable circumstances.

In practice, this means businesses must be able to demonstrate that their internal pricing reflects what the market would dictate for equivalent transactions — not what is most tax-efficient for the group.

Which Businesses Are Affected?

Transfer pricing rules apply to any business with:

  • Entities (subsidiaries, branches, or affiliates) in more than one country
  • Cross-border transactions between related entities (intercompany transactions)
  • Common ownership or control between the transacting parties

This includes not just large multinationals — mid-sized companies with even a single foreign subsidiary need to take transfer pricing seriously.

Common Types of Intercompany Transactions

  • Goods: A manufacturer selling products to a related distributor in another country
  • Services: A parent company providing management, IT, or accounting services to subsidiaries
  • Intellectual property: Royalties charged by a holding company to subsidiaries for use of patents, trademarks, or software
  • Financing: Intercompany loans and the interest rates charged on them

Transfer Pricing Methods

Tax authorities accept several methods to establish arm's length pricing. The choice of method depends on the nature of the transaction and the availability of comparable data:

  1. Comparable Uncontrolled Price (CUP): Compare the price to similar transactions between independent parties
  2. Cost Plus: Determine cost of goods/services and add an appropriate profit markup
  3. Resale Price Method: Start with the resale price and work backwards, deducting a gross margin
  4. Transactional Net Margin Method (TNMM): Compare net profit margins to those earned by comparable independent companies
  5. Profit Split: Allocate combined profits based on each party's contribution to value creation

Documentation Requirements

Most jurisdictions require businesses to maintain contemporaneous documentation supporting their transfer pricing policies. Following the OECD's three-tiered documentation approach (now adopted by many countries), this typically includes:

  • Master File: Group-level overview of the business, value chain, and global transfer pricing policies
  • Local File: Detailed analysis of specific intercompany transactions in each jurisdiction
  • Country-by-Country Report (CbCR): Required for large multinationals — reports revenue, profit, tax paid, and key metrics by country

Penalties for Non-Compliance

Transfer pricing adjustments and penalties can be severe. Tax authorities can:

  • Reallocate income from low-tax to high-tax jurisdictions
  • Charge back taxes, interest, and penalties — sometimes covering several years
  • Apply additional surcharges for lack of documentation (often 20–40% of the underpayment)

Proactive Steps for Compliance

  1. Map all intercompany transactions annually
  2. Establish and document a defensible pricing policy for each transaction type
  3. Maintain contemporaneous documentation — don't wait until an audit
  4. Consider an Advance Pricing Agreement (APA) with tax authorities for certainty on key transactions
  5. Work with international tax advisors to stay current with evolving OECD guidelines and local legislation

Transfer pricing is complex, but the risks of ignoring it are far greater than the cost of getting it right. For any business operating across borders, it deserves a place on the compliance agenda from day one.
