The changing global tax landscape – why businesses need to act now

Tax compliance is a key prerequisite

Robust tax compliance is a fundamental prerequisite for achieving tax stability. This includes adhering to all the tax and regulatory requirements in every country in which the company operates. There are already significant differences between countries regarding the question of when a company is considered to be “operating locally”. Seemingly minor activities such as placing online advertisements in other countries or employing supposedly external staff across borders can already trigger tax obligations.

Companies are required to design their global processes in such a way that they ensure that local documentation, reporting and audit requirements can be met at all times. At the same time, tax regulations are inherently dynamic and often subject to rapid changes. Despite harmonisation efforts, such as within the EU, national tax systems remain only partially aligned in practice, with regulatory updates occurring at an increasingly accelerated pace.

International transparency standards are adding further pressure on CFOs, while markets continue to become more volatile. Initiatives such as BEPS (base erosion and profit shifting), the global minimum tax under Pillar Two, and enhanced transparency requirements are creating new standards. Though intended to foster legal clarity, in practice, however, they are adding to the complexity. The tax landscape is therefore undergoing a profound structural transformation.

Key drivers of this trend include the globalisation and digitalisation of business models. Value creation and physical presence are becoming increasingly disconnected, for example through digital distribution models or individual employees working abroad. This makes it significantly more difficult to clearly attribute economic activities to a specific tax jurisdiction, something which calls for new approaches to the allocation of profits for tax purposes. In parallel, political and social pressure is mounting on countries to protect their tax base and curb cross-border tax avoidance schemes.

At the same time, countries continue to exercise their fiscal sovereignty, implementing international standards differently or supplementing them with national rules. The result is a growing level of fragmentation alongside ongoing harmonisation efforts. For international companies this means that it is essential to continuously adapt. What is needed are hybrid models that combine centralised governance and coordination with local flexibility to ensure both consistency and compliance.

Digitalisation of tax authorities is also a key driver

Another main driver is the digital transformation of tax administrations. This is fundamentally changing the way businesses and public authorities interact. Tax authorities are increasingly relying on data-driven audits, automated analyses and real-time access to transaction data. This is particularly evident in mandatory e-invoicing and reporting requirements, where structured transaction data often has to be transmitted in real time.

For companies doing international business this means significantly higher demands in terms of data quality, system integration and process harmonisation. A prime example is mandatory e-invoicing in countries such as Italy, where invoice data is transmitted directly to the tax authorities via government platforms and validated on them. Other relevant examples can be found in Poland and Spain.

Tax requirements are thus evolving from a static set of rules into a dynamic, real-time control environment. The stability of taxes can no longer be ensured through traditional compliance alone – it must be actively managed as part of a broader strategic framework.

To achieve this, international companies require a flexible global tax strategy and an appropriate delivery model. They need to be reviewed on a regular basis and refined specifically in response to significant regulatory or internal business changes. The tax strategy should be embedded in a global governance model that clearly defines responsibilities, takes local differences into account and establishes standardised processes for reporting and control.

In practice, however, central rules and policies are often not implemented consistently – for example, due to local priorities, differing regulatory requirements or a lack of coordination. Fragmented and non-standardised processes not only cause tax disadvantages & risks, but also lead to inefficient workflows, higher costs and delays in decision-making.

Conclusion

The increasingly dynamic global tax landscape is fundamentally changing the role of the tax function. While the focus used to be primarily on compliance with local regulations, today an integrated, proactive approach to tax management is required. Companies need to anticipate tax developments at an early stage, align their processes globally and continuously refine their tax strategy.

This makes it clear that the real challenge lies less in individual regulations and more in managing the interplay of different requirements, processes and responsibilities. In the next article in this series, we will explore the specific tax risks that arise from this and how they interrelate.
