Is zakah obligatory on the money remaining from my salary?

Question:
This questioner says: I have an account in the bank where I deposit my salary at the end of every month, and I withdraw my expenses through the automated teller machine. Is zakah due on the money remaining in the account at the end of the year, given that the remaining money is mixed together across all the months?

Answer:
Yes, if a lunar year has passed over it, zakah is obligatory on it, provided it reaches the nisab (minimum threshold for zakah) and a lunar year has passed over it. However, if you and other employees are in a situation where you say, "I am unable to determine the hawl (lunar year of possession) for each amount, because I deposit a balance every month," then it is better to designate a time of the year, such as Ramadan, to pay out all the accumulated balance, whether a lunar year has passed over it or not, to the equivalent amount in the coming year. By doing this, your obligation is discharged. This is the ruling upon which the fatwa (scholarly legal ruling) is based and upon which one should act now. Yes.
