Praise be to Allah, the Lord of the Worlds; and blessings and peace be upon our Prophet Muhammad and upon all his Family and Companions.
Paying Zakah of money becomes obligatory with two conditions:
1. The money should complete the Nisaab.
2. One Islamic year (Lunar) should pass after possessing the money.
Dear brother, if all your money in the form of cash in your account, or in the form of shares in their current values complete the Nisaab and an Islamic year has passed after owning the Nisaab then you have to pay the Zakah of that money.
As for your loans, after deducting those loans which you have to pay urgently, if the money completes the Nisaab then you have to pay its Zakah. If this is not the case, paying Zakah is not compulsory on you.
For more details please refer to fatwa : 82055.
Allah knows best.
