Is it permissible to evade the taxes imposed on people, and what is the ruling on working in the tax authority?

The Shaykh : In the name of Allah, the Most Gracious, the Most Merciful.
This person says that in some countries, they impose taxes on people, and these taxes are usually deducted from the poor rather than the rich. Is it permissible for a person to evade these taxes and not pay them, and what is the ruling on working in the tax authority?
There is no doubt that it is permissible for a person to flee from injustice, and he owes nothing for doing so, but without confrontation. That is, it is not permissible to confront the rulers who impose these taxes, due to the saying of the Prophet (peace and blessings be upon him): As for fleeing from them without confrontation, for example, a person hides things, and there is nothing wrong with that because it is fleeing from injustice. As for working in these jobs, if a person wants to take a position in order to reduce the injustice, then there is nothing wrong with that, and he will be rewarded for it. But if he takes a position in it to increase this injustice and not alleviate it, then it is not permissible, because it is not permissible to assist the oppressor in his oppression. Yes.
