Global tax systems are facing challenges due to cross-border income and tax evasion. The OECD introduced the Common Reporting Standard (CRS) in 2014 to improve international information exchange between tax authorities. The CRS aims to combat offshore tax evasion by requiring banks to share taxpayer information globally. While the CRS has benefits in reducing tax evasion, concerns remain about its coordination with other information exchange models and protecting taxpayers' rights and information.
