Zakat on Debt — What You Can Deduct
Short-term debts currently due — credit cards, personal loan payments, bills — are deductible from your zakatable wealth. Long-term debts like mortgages and most student loans are not. Here is the complete scholar-reviewed guide to every common UK debt type.
The rule: Only current liabilities — debts due within the next 12 months — are deductible from your Zakat calculation. Long-term liabilities (most of a mortgage, long-term loans, income-contingent student loans) are not deductible. Deduct what you genuinely owe now; pay 2.5% on the remainder.
Debt deductibility at a glance
| Debt type | Deductible? | Rule |
|---|---|---|
| Credit card balance | Deductible | The full outstanding balance on your credit card on your Hawl date is a short-term debt you can deduct. |
| Personal loan (next 12 months) | Deductible | Only the repayments due within the next 12 months are deductible — not the full outstanding loan balance. |
| Student loan (UK income-contingent) | Not deductible | UK student loans are repaid contingently from earnings only above a threshold — most scholars treat them as non-deductible since repayment is not a fixed obligation due now. |
| Car loan | Partially deductible | The instalments due within the next 12 months are deductible. The remaining future repayments are not. |
| Mortgage | Not deductible (mostly) | Only the next monthly payment due is deductible for most scholars. The full mortgage balance is a long-term debt and not deducted. See our Zakat with mortgage guide. |
| Unpaid utility bills | Deductible | Bills currently due and outstanding are a short-term liability — deduct the full amount. |
| Money you owe to family / friends | Deductible | Loans owed to individuals (not banks) that are currently due are deductible. |
| Business debt (sole trader) | Deductible from business Zakat | Business liabilities directly associated with Zakat-liable trade stock can be deducted from the business Zakat calculation. |
Worked example
Ahmed's Zakat calculation on his Hawl date:
Ahmed's mortgage is not deducted (only the next month's payment would be, and he chose to use the conservative majority ruling of not deducting it). His UK student loan is not deducted.
The mortgage question in detail
This is the most common question UK Muslims ask. Here is the range of scholarly opinions:
- Majority position (no deduction): A mortgage is a long-term debt secured on an asset (your home). The home itself is exempt from Zakat, and most scholars hold the associated long-term liability cannot be deducted either.
- Minority position (one month deductible): Some scholars permit deducting the next monthly payment only — the portion of the debt that is "currently due."
- Some contemporary scholars: Allow deducting up to 12 months of mortgage payments — the amount due in the next Hawl year.
Our Zakat with mortgage guide covers this in full detail with all scholarly positions.
Frequently asked questions
Can I deduct debts from my Zakat?
Yes — short-term debts (those currently due or coming due within the next 12 months) can be deducted from your total zakatable wealth before calculating Zakat. Long-term debts like a mortgage are generally not fully deductible — only the next payment due counts.
Can I deduct my full mortgage from Zakat?
No. Most scholars hold that only the next monthly mortgage payment is deductible. The full outstanding mortgage balance is a long-term liability, not a current debt. Deducting the entire mortgage would make Zakat negligible for most UK homeowners with investment assets — which is not the intent of Islamic law.
Can I deduct my UK student loan?
The majority of contemporary UK scholars hold that income-contingent student loans (Plan 1, Plan 2, Postgraduate) are not deductible as Zakat debts. The reasoning: repayment is conditional and income-dependent, not a fixed obligation due now. You only repay if you earn above the threshold, and the debt is written off after 30–40 years. It is not a conventional debt you 'owe' in the same sense as a credit card or personal loan.
What about money I owe to family or friends?
Yes — if you genuinely owe money to family or friends that is currently due (or you have agreed to repay soon), this is a deductible debt. It must be a real obligation, not a token amount invented to reduce Zakat. Charitable intent cannot be achieved through bad-faith accounting.
Is a car loan deductible from Zakat?
Partially. The repayments due within the next 12 months can be deducted. The remaining future repayments (years 2, 3, 4 of a loan) are not yet 'due' and cannot be deducted. This follows the principle that only currently due debts are deductible, not future obligations.
Do I deduct my total debts from all my wealth?
Yes — you calculate your total zakatable wealth, then subtract all currently-due liabilities, and pay 2.5% Zakat on the net figure. If your total debts exceed your zakatable wealth (after deductions), your net is zero and no Zakat is due that year.
