About
The most widely adopted free and open-source engine to write rules as code
Government departments, lawmakers and civil society finally share a common language to debate and activate social and fiscal policies: OpenFisca enables collaboratively modelling laws and regulations and making them computable over open APIs for developers, datascientists and researchers.
Policy experts and governments
OpenFisca enables institutions to efficiently share regulation updates and to pool IT costs. Interconnecting rules across public bodies in the form of legible parameters and executable code provides algorithmic transparency and reduces the bill for the taxpayer.
Developers and datascientists
OpenFisca enables developers to easily deliver apps calculating complex taxes and benefits through its JSON web API, and datascientists to compute large-scale through its vectorial Python API. Contributing formulas and coding extensions enables building services for any business.
Economists and researchers
OpenFisca enables economists and researchers to use survey and administrative data to simulate the impact of any past or future reform on the income distribution of a given population. Linking all computed taxes and benefits enables analysing how multiple reforms interact.
International recognition
- OpenFisca is recommended by the OECD to enable “better policy outcomes and enhanced service delivery”.
- Received the Edge of Government Innovation Award 2023 at the World Government Summit
- Received the Most Innovative Open-Source Software Award 2019 by the European Commission
