Digital platform for secure tax calculation

The challenge

With the introduction of the global minimum tax under Pillar 2, the requirements for international tax calculations changed fundamentally. Our client wanted to integrate these new rules into its existing service platform at short notice. The solution had to reliably handle complex calculations, consolidate financial data, and ensure that changes were traceable at all times.

Our customer

The client is an internationally active tax consulting and auditing firm. Through digital services, it helps companies implement complex tax requirements efficiently and in compliance with regulations.

How we helped

We expanded the existing platform with key features for calculating global minimum taxation. Our goal was to map the complex tax rules in a way that ensures results remain understandable and verifiable.

To ensure all relevant data changes are transparently documented, we implemented an event-sourcing approach. This ensures seamless traceability and significantly enhances the integrity of data processing. Additionally, we integrated validation rules for exceptions such as the Safe Harbor De Minimis rule. These form the foundation for enabling accurate and consistent calculations in the first place.

Another benefit: The available export functions make the results immediately usable for further consulting.
