What is the ruling of religion on working in accounting offices or companies that falsify ledgers and budgets to evade taxes, and what is the ruling on one who can remain unemployed for a period, with his practical experience being affected thereby?

It is permissible to evade illegitimate taxes by any means to repel injustice, and there is no sin upon the one who does so or upon the employer. As for legitimate taxes, it is not permissible to evade them. In cases where evasion is not permissible, it is not permissible to work [in a way that necessitates evasion], because that is not an excuse for committing what is forbidden. Forbidden acts are not made permissible except out of necessity, and the loss of experience is not considered a necessity that permits what is forbidden.
