The General Rule of Liabilities

In Islamic jurisprudence, Zakat is paid on 'Net Assets'. This means you calculate your total wealth and subtract any immediate liabilities (debts) that you owe to others. This ensures Zakat is only paid on wealth you truly own and have access to.


Which Debts Can Be Deducted?

Not all debts are treated equally. Scholars differentiate between immediate commercial debts and long-term financing.

Fully Deductible

Debts due immediately or within the current lunar year. Examples: Personal loans due now, unpaid utility bills, shop rentals due, employee salaries.

Partially / Non-Deductible

Long-term debts not due immediately. Most scholars suggest deducting only the upcoming 12 months of payments, not the total loan amount.

Mortgages & Car Financing

If you have a 20-year home mortgage, you cannot deduct the entire debt, as this would likely reduce your wealth to zero, exempting you from Zakat unfairly.

"The preferred view is to deduct only the amount of installments due for the upcoming lunar year. The remaining principal balance is ignored for Zakat calculation."

Frequently Asked Questions

Q.I have a student loan. Do I deduct the whole amount?

No. You should only deduct the amount that is payable within the current year. The long-term portion is not deducted.

Q.Can I deduct the Mahr (Dowry) I owe my wife?

If the Mahr is 'Mu'ajjal' (due immediately upon demand), you can deduct it. If it is deferred to a later date (death or divorce), it is not deducted.

Q.I took a loan to buy a house for investment. Is it different?

Yes. If the house is for trade (business stock), you pay Zakat on the house value but deduct the debt. If it is for rental, you pay Zakat on the rental income, not the house value.
