Interest money

Using interest to offset bank charges and disposing of interest money

Q: I have both a current account as well as a savings account at the same bank. On both the accounts, the bank levies bank charges, but the savings account is interest-bearing.

In this situation, can the interest received on the savings account be used to pay the charges levied on both accounts by the bank?

If not, then to whom should the interest be given? Can it be given to non-Muslims and even to street beggars or beggars knocking on doors every week?

Using interest money to pay tax

My father have 7 dependents under him which and we are paying government more than 40,000 riyal from our halal earned money. In this case, is it possible to pay them by depositing our money in fixed deposits and give them interest amount and get rid of it?
