One of the key trends that we are likely to see in the future is a greater degree of harmonization in international tax rules. The global minimum tax rules represent a major step towards creating a more level playing field for MNCs, by ensuring that they are subject to a minimum effective tax rate regardless of where they operate. This trend towards harmonization is likely to continue as countries seek to prevent tax avoidance and ensure that tax revenues are fairly distributed.

With the implementation of global minimum tax rules, MNCs will face increased compliance and reporting requirements. They will need to carefully track their global revenue and tax payments to ensure that they meet the minimum effective tax rate. This may require significant changes to their tax planning strategies and the way they manage their tax affairs.

Another trend that we are likely to see is the rise of digital taxation. As more and more economic activity takes place online, there is growing pressure on governments to tax digital services and products. Global minimum tax rules may pave the way for the introduction of new digital taxes, as countries seek to ensure that digital companies pay their fair share of taxes.

While global minimum tax rules represent a step in the right direction, there are still many challenges ahead. One of the biggest challenges is ensuring that the rules are implemented effectively and consistently across different jurisdictions. There is also the challenge of addressing the concerns of developing countries, which may see their tax revenues impacted by the new rules.
