Can a Muslim work as an accountant or auditor?

“1. The client has hired your services as an accountant to calculate the income tax due on his earnings and to submit returns on his behalf. There is no harm in offering such a service to the public in lieu of a fee since submitting returns to the revenue is a legal requirement for all citizens.”

“A college of chartered accountancy teaches people how to become an accountant. This is permissible.”

“It is permissible for one to work as a chartered accountant, provided one is not asked to engage in something impermissible and one is not hired by a company that is involved in haraam (e.g. being an accountant for a bank or a brewery).”

“No, it won’t be permissible to do bank auditing. To work for the conventional banks is not allowed.”
