Depositing money in Riba-based banks is not permitted unless it is absolutely necessary to safeguard the funds. To commit the smaller of two evils, and because necessity should not be exaggerated, one must confine oneself to putting money in current accounts solely [i.e., those that do not pay interest]. If interest is paid on the money placed, it must be spent on various charitable projects to get rid of it. As a result, because the basic interpretation of the evidence is that Riba (interest) is Haraam (prohibited) in Islam, it is not permitted to open an interest-based account and utilize it to pay off taxes with this money.
