Are the incentive bonuses received from working at the General Treasury in Morocco, the source of which is interest from loans granted to municipalities or punitive fines imposed for delays in tax payments, permissible (halal) or forbidden (haram), and what should an employee do if they are forbidden?

What the Ministry of Finance does by lending and what the Tax Department does by imposing fines on those who are late in paying taxes is haram (forbidden). As for the ruling on employees accepting incentive bonuses that they know their department obtained from usurious loans or from taxes and late payment fines, the preponderant opinion is that money is not designated by designation. Therefore, there is no harm for employees in taking these bonuses. Dealing with someone whose wealth is mixed with halal (permissible) and haram (forbidden) is disliked, unless the transaction is specifically in the haram money itself. The employee takes his commission from the general funds of the department, which include both halal and haram, and it does not concern him that his department's intention is for the bonuses to come from those interests, taxes, and fines.
