TaxEngine
Powerful, reliable, and transparent, TaxEngine enables governments to manage tax calculations and policy implementation at scale. By orchestrating open-source projects with domain expertise, it ensures digital sovereignty, interoperability, and maintainability.
A unique tax system, modernized
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 of 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.

Frequently asked questions
What is TaxEngine?
TaxEngine is a powerful and reliable tax computation engine powering France's complete fiscal ecosystem. It handles 37 million tax declarations annually with full transparency and digital sovereignty.
Can non-developers modify tax rules?
Yes. TaxEngine is designed so that domain experts (tax specialists and policy makers) can directly modify computation rules without depending on software developers.
What is the M language?
The M language is the domain-specific language used by TaxEngine for tax computation, in use since the 1990s. The TaxEngine project has been modernizing it since 2021 for improved maintainability and performance.
Does TaxEngine provide execution tracing?
Yes. TaxEngine includes a built-in execution tracing tool that lets you debug and audit tax computations step by step, ensuring full transparency in how results are derived.
Can TaxEngine integrate with existing systems?
Yes. TaxEngine provides interoperable interfaces and APIs for integration with existing fiscal simulators and complementary calculation engines for corrections and penalties.
