All perfect praise be to Allah, The Lord of the Worlds. I testify that there is none worthy of worship except Allah, and that Muhammad is His slave and Messenger.
Paying Zakat of money becomes obligatory with the following conditions:
1. The holdings gold, silver, money should complete the Nisaab (minimum amount liable for Zakat), which is 85 grams of gold or its equivalent. (See newspaper or consult a bank to determine its value.)
2. A whole lunar year should have passed after owning it. The Zakat is only paid on the money which remains after satisfying the basic needs of a person and settling all his debts.
3. You may take the Government loans that have no interest/usury. If there is interest or usury then taking them is forbidden, as Allah Says (what means): {O you who have believed, fear Allah and give up what remains [due to you] of interest, if you should be believers.} [Quran 2: 278]
For the ruling of Zakat for an indebted person, please refer to Fatwa 82490.
Allah knows best.
