What is the ruling on working for the Tax Authority and in financial penalties for criminals, taking into account that Tunisia relies on these taxes as a primary economic resource, and that the questioner has no other work?

An employee involved in collecting taxes and financial penalties is exposed to great danger, especially in times when injustice is widespread and justice is absent. He must seek out lawful work in which he is not an oppressor or an assistant to an oppressor, and he must avoid forbidden situations. The claim that there is no permissible work is incorrect; for with patience and searching, a Muslim can find lawful work, in accordance with the Almighty's saying: "And whoever fears Allah - He will make for him a way out And will provide for him from where he does not expect."
