Question
I am a bank employee. To start my job, I deposited 500,000 tumans in the bank (of course, this money is kept in my name in a long-term savings account and I receive its interest every month). Is it obligatory to pay khums on this money, considering that this money has been deposited with the bank for four years?

Answer:
The deposited money is not subject to khums as long as you are not able to withdraw it. But its interest - after the deduction of yearly ma’ūnah - is subject to khums.
