    <dct:description>&lt;p&gt;In France, income tax is computed from taxpayers&amp;rsquo; individual returns, using an algorithm that is authored, designed&amp;nbsp;and maintained by the French Public Finances Directorate&amp;nbsp;(DGFiP). This algorithm relies on a legacy custom language&amp;nbsp;and compiler originally designed in 1990, which unlike French&amp;nbsp;wine, did not age well with time. Owing to the shortcomings of the input language and the technical limitations of&amp;nbsp;the compiler, the algorithm is proving harder and harder&amp;nbsp;to maintain, relying on ad-hoc behaviors and workarounds&amp;nbsp;to implement the most recent changes in tax law. Competence loss and aging code also mean that the system does not&lt;br&gt; benefit from any modern compiler techniques that would&amp;nbsp;increase confidence in the implementation.&amp;nbsp;&lt;/p&gt; &lt;p&gt;We overhaul this infrastructure and present Mlang, an&amp;nbsp;open-source compiler toolchain whose goal is to replace&amp;nbsp;the existing infrastructure. Mlang is based on a reverse-engineered formalization of the DGFiP&amp;rsquo;s system, and has&amp;nbsp;been thoroughly validated against the private DGFiP test&lt;br&gt; suite. As such, Mlang has a formal semantics; eliminates&amp;nbsp;previous hand-written workarounds in C; compiles to modern languages (Python); and enables a variety of instrumentations, providing deep insights about the essence of French&amp;nbsp;income tax computation. The DGFiP is now officially transitioning to Mlang for their production system.&lt;/p&gt; &lt;p&gt;This is the artifact accompanying the published paper at Compiler Construction 2021.&amp;nbsp;&lt;/p&gt; &lt;p&gt;&amp;nbsp;&lt;/p&gt;</dct:description>
