Enhanced penalties for repeat tax offences impose mandatory imprisonment and fine upon subsequent convictions under specified tax provisions.
A prior judicial conviction under any specified income tax offence triggers enhanced punishment: a person again convicted under any of those listed offences is subject to mandatory rigorous imprisonment and a mandatory fine, regardless of whether the subsequent conviction is for the same or a different listed offence; judicial discretion governs the precise sentence within the prescribed range, and the provision applies only after a prior conviction, not mere charge or prosecution.
