The following content is for general reference only and cannot replace the advice of professional tax, legal and financial advisors. In international trade, many multinational companies will use internal inter-enterprise transaction prices (i.e. transfer pricing) to reasonably allocate profits among member units within the group, thereby optimizing the overall tax burden. It must be emphasized that all transfer pricing arrangements should strictly comply with the laws and regulations of relevant countries and regions and international standards (such as the OECD's Transfer Pricing Guidelines and local regulations of various countries) to ensure that pricing complies with the "arm's length principle", otherwise there may be audit, penalties or even legal risks. Here are some common basic ideas and key points for reference: 1. Clarify the arm's length principle • The core principle requires that the pricing of transactions within the group should be consistent with the pricing of similar transactions between unrelated parties. • Enterprises need to determine reasonable market prices through market research and benchmarking (Benchmarking Analysis). 2. Choose an appropriate transfer pricing method • Common methods include comparable uncontrolled price method (CUP), resale price method, cost plus method, profit split method and transactional net profit method. • Which method to choose depends on the nature of the transaction, the characteristics of the product or service, and the available data. 3. Build a sound documentation and compliance system • Detailed transfer pricing documentation, business process descriptions and economic analysis reports are key to accepting tax authorities' review. • Enterprises need to update these records regularly and keep them synchronized with market conditions, economic conditions and internal business models. 4. Analyze the value chain and functional division of labor • Evaluate the actual contribution of each member unit in R&D, production, marketing, brand management, logistics and after-sales service, and reasonably allocate risks and profits. • This analysis requires in-depth research on the functions, assets and risks of each business unit within the group to provide supporting data for transfer pricing. 5. Tax optimization strategy and risk balance • Setting reasonable transfer pricing can sometimes reasonably allocate profits between high-tax and low-tax countries, thereby reducing the overall tax burden. • However, it should be noted that the more aggressive tax planning is, the more likely it is to attract the attention of the tax authorities. It should be kept within a reasonable range to avoid being identified as tax evasion or erosion of the tax base. • Communicating with the tax authorities in advance or taking the advance pricing agreement (APA) procedure is also an effective way to reduce uncertainty and compliance risks. 6. External environment and multinational regulation • In the context of global anti-tax avoidance actions and the digital economy, regulators in various countries have paid more and more attention to transfer pricing issues. • In addition to traditional forms of trade, new business models such as digital products, intellectual property rights and services also need to pay special attention to the rationality of pricing to prevent being identified as profit erosion and profit shifting (BEPS) behavior. 7. Combined with overall tax planning strategy • Tax optimization is not limited to transfer pricing, but also involves the use of bilateral tax treaties, the selection of appropriate corporate structures, funding arrangements and other cross-border planning tools. • Various measures need to be coordinated as a whole to ensure that all aspects comply with legal provisions and that tax rate optimization can be achieved under the premise of controllable risks. Overall, using transfer pricing for tax optimization is a complex topic that involves not only economic analysis, but also issues in multiple fields such as accounting, taxation, and law. When taking relevant measures, enterprises should: – Conduct a full economic analysis of all transactions to ensure the market rationality of prices; – Establish a systematic internal control and compliance management mechanism to ensure transparency and dynamic adjustment; – Regularly evaluate and update transfer pricing policies to track changes in the international tax environment; – Communicate with professional institutions or tax lawyers when necessary to seek approval from tax authorities (such as obtaining agreements such as APA). Please note that the content discussed in this article is only a general description. Any specific implementation plan must be combined with the actual situation of the enterprise and formulated under the premise of complying with applicable laws and regulations. Please be sure to consult professional tax and legal advisors before implementation to ensure that all operations are legal, reasonable and in line with the long-term development needs of the enterprise.
