Q: A person deals mostly in cash and does not deposit in the bank in order to avoid showing too much income and paying exorbitant amounts of tax to the government. However, he cannot purchase large items such as properties and cars etc as it has to be done with "legal" money.
The only way out for him will be to take a loan from the bank in order for his purchases to be recognized legally. He will offset the interest payable with the interest he receives from his bank account.
Can this be a valid excuse to enter into an interest bearing loan with the bank?
