A dozen of affiliate companies owned by an American information technology group had experienced extensive reorganizations and transferring of staff after a series of mergers and acquisitions. As a long-term strategic partner, GFC suggested the company in advance to concentrate on its operation status, level of profitability, as well as tax burden situation, to collect financial data and pay close attention to inner relationships and changes of the data, in case of any particular concern and stringent review from tax authority. GFC also helped them to prepare the corresponding materials, which explained the changes caused by reorganization from five aspects, including: organization structure, production operation, related-party transactions, comparison analysis and choice of transfer pricing method. In these high-quality materials, GFC fully considered particular cases and made professional analysis, illustrated company’s condition reasonably, also explained some unusual fluctuations with sufficient argument, and eventually gained approval and support from tax authority, which greatly reduced the risk of tax adjustment.
