Is it permissible, from a Sharia perspective, to pay workers' expenses from social security and taxes from the bank interests deposited in the client's account at the Algerian Savings and Provident Fund, knowing that the client does not utilize these interests?

It is not permissible to deposit money in interest-based banks except in cases of extreme necessity, such as fear of loss and the absence of Islamic banks. In such a situation, it is permissible to deposit only in a current account. One must repent to Allah and dispose of the usurious interest by spending it on the welfare of Muslims or on the poor and needy. It is not permissible to use it to pay social security or taxes.
