Is zakaah due on bonuses?

The company for which I work gives fifteen days’ wages as a bonus at the end of every year of service, but this bonus comes at the end of the period of service. If I take this bonus after the end of the period of service, is zakaah due on it or not?.

Praise be to Allah, and blessings and peace be upon the Messenger of Allah:

If the situation is as described, then no zakaah is due on that bonus until you receive it, and one year has passed from the time of receiving it. End quote.
