Yes, companies can indeed conceal the true source of profits through cross-regional accounting processing. This practice is often called "transfer pricing" or "profit shifting." These methods may include： 1. Subsidiaries in high-tax regions pay high intellectual property royalties or management fees to affiliated companies in low-tax regions 2. Transfer profits from high-tax areas to low-tax areas through irrationally priced internal transactions 3. Use internal loan arrangements to allow subsidiaries in high-tax regions to pay high interest rates to affiliated companies in low-tax regions 4. Set up a holding company or procurement center in a tax-advantaged area Although these practices may technically meet the literal requirements of local regulations, many countries and international organizations (such as the OECD) are strengthening supervision and implementing measures such as "substantive requirements", "anti-tax avoidance rules" and "country reports" to combat improper profit transfer. It is worth noting that there is a clear distinction between legal tax planning and illegal tax evasion. Multinational companies should ensure that their cross-regional transactions comply with the "arm's length principle" and the requirements of national tax laws.
