Yes, strategies to hide ill-gotten gains and evade taxes using complex corporate structures do exist. These strategies are often referred to as “patches” or “arrangements,” and they can involve creating and utilizing a complex web of entities, royalty payments, and other financial instruments to minimize taxes and hide ill-gotten gains. Here are some examples: 1. **Offshore entities**: Creating subsidiaries or affiliates in low-tax or no-tax jurisdictions, such as Delaware, the Cayman Islands, or Bermuda. These entities can be used to hide gains, avoid taxes, and undermine transparency. 2. **Transfer pricing**: Using sham transactions between affiliates (entities that are affiliated with the same parent company or have common ownership) to shift profits and minimize taxes. 3. **Royalty payments**: Paying royalties (such as patents or copyrights) to another affiliate that is located in a low-tax or no-tax jurisdiction in order to shift profits from a high-tax country to a low-tax country. 4. **Hybrid entities**: Using hybrid entities (such as limited liability companies or partnerships) that look like overdraft entities in one jurisdiction and non-overdraft entities in another jurisdiction, thereby creating a "double non-resident" status to avoid tax. 5. **Trust and foundation structures**: Using trusts or foundations to hide ownership, management, and control around the income of assets. 6. **Anonymous ennie empresas**: Using anonymous or quasi-anonymous structures (such as shell companies, virtual entities) to hide holdings, ownership, and decision-making processes. 7. **Money laundering techniques**: Using money laundering and other financial crime techniques to obscure the source and ownership of funds. 8. **Regulatory arbitrage**: Taking advantage of different jurisdictions, regulations, and accounting systems, using differences to minimize taxes and crypto transactions. 9. **...') 10. **Complex cross-holdings**: Often using a grid structure of entities between each other to minimize transparency and tax burden. These complex structures often involve multi-jurisdictional planning, financial engineering, and carefully planned transactions to minimize tax burden. They can be used to conceal unethical income, such as bribery, tax evasion, or other forms of corruption. Please note that these strategies may not necessarily be legal or ethical, and jurisdictions are working to combat them by preventing the exploitation of tax loopholes and hiding of improper gains. It is also important to remember that not all complex corporate structures are designed for the purpose of tax evasion, and many legitimate businesses use complex structures to manage risk, optimize operations, or achieve legitimate business objectives.
