- Open source and maintainable
- Digital sovereignty and full control
About TaxEngine
The story of a unique tax system and its modernization
In the 1990s, France's DGFiP developed the M language, enabling jurists and tax specialists to directly define tax rules. This unique system has reliably processed millions tax declarations annually with exceptional performance and reliability.
Over time, the increasing complexity of tax laws made modernization necessary: the TaxEngine project was born to regain technical mastery and robustness.
Modernization with TaxEngine
Since 2021, Titagone is transforming the DGFiP M prototype (MLang) into TaxEngine, a maintainable and industrial-ready tax engine. This project allowed us to gain deep expertise in tax computation and software modernization, forming the foundation for our TaxEngine offering - designed to help organizations build reliable, high-performance tax solutions.
Our Expertise
Proven technical and methodological know-how
Reliability at scale
Our technology handles the entirety of French tax declarations, processing 37 million returns annually with proven reliability and performance at the highest scale.
Domain Expert Accessibility
Tax specialists and jurists can directly intervene on tax rules, bridging the gap between legislation and technical implementation.
Simplified Maintenance
Code modernization and elimination of fragile intermediary code, making the system easier to maintain and evolve over time.
Training & Knowledge Transfer
DGFiP teams are autonomous thanks to comprehensive training and knowledge transfer programs.
Dedicated and Robust Tooling
We develop specialized tools to ensure reliability and facilitate debugging in complex tax computation systems.
Our execution tracing tool allows developers and domain experts to trace the complete flow of computations, making it easy to identify the source of bugs and verify calculation accuracy at every step.
