Show HN: 美国个人所得税计算器，从1970年到现在 (Show HN: Calculator for US individual income tax, from 1970-present)
This WASM build now powers https://taxsim.app, which is my attempt to create an interactive UI to allow for easier exploration of the US tax code. Specific tax scenarios can also be shared easily, by simply copying the browser URL. The code for this webapp is also open-source [6].

Open Source Tax Software
The french initiative started in 2013 is still alive (last commit a few days ago), and passes the gov test suite (they keep in touch with our version of the IRS): https://github.com/openfisca/openfisca-france
The way we got this is interestingly twisted.
French citizens requested the software used by the administration, and they managed to get it!
But, it's was written in Mlang is a proprietary language created by the french administration in the 90: https://github.com/MLanguage/mlang.
Someone then decided to create an OCaml compiler that takes mlang and emits python: https://arxiv.org/abs/2011.07966
As a result, we got we got open fisca. I know believe there are other techs in the mix...

Code isn’t law—law is law
They have open sourced the algorithm they use to compute taxes here: https://gitlab.adullact.net/dgfip/ir-calcul which used a purpose made programming language https://github.com/MLanguage/mlang

Software engineers make the best CEOs, at least when measured by market cap
It's important to note that this isn't universal across the entire legal system. Some subsets like France's tax system are defined in code, and there's some efforts to create more general systems as computational law advances as a field.
