Is zakah obligatory on salary money?

Question:
May Allah reward you and bless you. This questioner says: Honorable Shaykh, I have a bank account to which my salary is transferred. I take from my salary what I need, so sometimes some of this salary remains, and sometimes nothing remains. Is there zakah on that, and how is it calculated? Is the condition that a lunar year passes over it without it decreasing or increasing?

Answer:
If you have savings from your salary, savings in cash from your salary, and a lunar year passes over this surplus, then zakah is obligatory on it without doubt, provided that it has reached the nisab (minimum threshold for zakah). It must have reached the nisab under two conditions: first, that a lunar year passes over it, and second, that it has reached the nisab by itself or by combining it with other wealth on which zakah is obligatory. As for what has not completed its lunar year, zakah is not obligatory on it. However, if you wish to be cautious, you can set a specific month of the year as the time for paying zakah. You pay the zakah on what you have accumulated, both what has completed its lunar year and what has not, up to the same month in the following year. By doing this, you clear your conscience and make it easier for you to pay zakah. You pay the zakah on what is in your possession in that designated month, paying the zakah on the savings you have.
