It's used today in France for notably : - estimating the taxes on salaries eg. before hiring (1) - estimating one's (as a citizen) social benefits on a centralized web page (2) - for various economic studies (where the numpy implementation helps working on large inputs) The core (https://github.com/openfisca/openfisca-core https://github.com/openfisca/openfisca-core) package defines abstract structures used primarily but not specific to the France-specific package (-france), where the law is coded. Unfortunately, I don't think there is a way to bootstrap a new country (eg. generating templates for different kinds of taxes). -tunisia is the second country implemented, but much less maintained. "Extensions" enable local specifics to be added (e.g. specific to Paris). "Reforms" enable the simulation of experiments (e.g. simulating a basic income).
