Is it permissible for an employee of the Tax Authority to receive a sum of money to influence a colleague to be lenient in auditing a specific company?

Anything by which a person achieves the annulment of a right or the establishment of falsehood is considered prohibited bribery. Bribery is of two types: one is when a person uses it to achieve falsehood, to evade a rightful duty, or to obtain what is not theirs. This type is prohibited for both the giver and the receiver. Therefore, taking money from a colleague with the aim of influencing an auditing colleague to overlook some fixed tax liabilities is impermissible and falls under bribery. Even if the taxes are unlawful, one should endeavor to reduce them as much as possible, without any consideration.
