Is Debt Deducted From Zakat? What You Can Subtract, and What You Can't
The short answer
Most schools allow some debt to be deducted before calculating zakat, but not all of it. The common modern approach lets you subtract debts due within the coming lunar year, including the next twelve months of capital repayments on a long-term loan, then pay 2.5% on the rest if it meets the nisab. The Shafi'i school, in its best-known view, deducts nothing.
Yes, in most cases you can deduct some of your debt before you calculate zakat, but usually not all of it. The most widely followed modern approach lets you subtract debts you must pay within the coming lunar year, including the next twelve months of instalments on a longer loan, and then pay 2.5% on what remains if it still meets the nisab. Classical scholars differed on this question, so it is worth knowing why.
Is debt deducted from zakat at all?
Under most schools of Islamic law, yes, some debt is deducted. The idea is simple: money you already owe to someone else is not truly free wealth, so it should not be taxed as if it were. The Shafi'i school is the main exception. In its best-known view, debt does not reduce your zakat at all, and you pay on everything you hold that meets the nisab and has completed a lunar year.
The disagreement is old and respected. The Hanafi, Maliki and Hanbali schools, in their best-known positions, allow a person to subtract what they owe before testing their wealth against the nisab, though they differ in detail. The Malikis, for example, apply the deduction to cash, gold and silver rather than to crops and livestock. Several well-known modern scholars, including Shaykh Ibn Baz and Shaykh Ibn Uthaymeen, leaned towards the Shafi'i view, with Ibn Uthaymeen allowing only a debt that falls due before your zakat date and is actually paid (IslamQA, answer 120371).
If you already follow a scholar or madhhab, take their ruling. If you do not, the middle approach below is what most zakat bodies and calculators now assume.
Which debts can I deduct from my zakat?
The common answer today is: debts that are due now or within the next twelve lunar months. Guidance from the National Zakat Foundation in the UK, which follows this approach, lists four kinds:
- Bills and expenses already incurred that you will settle within twelve lunar months
- Arrears and overdue payments of any kind
- Personal loans from family or friends, up to the amount you intend to repay in the next twelve months
- The capital part of the next twelve months of repayments on a long-term bank loan
Interest is never deductible. If a loan carries interest, only the capital portion of the coming year's repayments counts.
A condition sits underneath all of this. In the classical sources, the scholars who allow the deduction generally require that you have no other spare wealth, beyond your basic needs, that could pay the debt (al-Mawsu'ah al-Fiqhiyyah, 23/247). In other words, the deduction exists to protect people who really need the money for their debts. It is not a way to avoid zakat while living comfortably.
Can I deduct my whole mortgage from zakat?
No. Almost no contemporary scholar allows you to deduct the full outstanding balance of a mortgage or other long-term loan. If that were allowed, many homeowners with large savings would owe no zakat at all, and some would even become eligible to receive it.
Contemporary Hanafi muftis explain the reasoning plainly: the full balance is not an immediate need, because the lender has no right to demand future payments today, and zakat rulings take the interest of the poor into account (IslamQA, Fatwa Centre). So the middle view lets you deduct up to one year of repayments. Some bodies are stricter still. Zakat Foundation of America allows only the single mortgage payment currently due on your zakat date, treated like any other living expense.
Your home itself is not zakatable, so there is no question of paying zakat on the house while also deducting the loan used to buy it.
How does the deduction change the calculation?
Here is a simple example using the twelve-month approach. Suppose that on your zakat date you hold the following:
| Item | Amount |
|---|---|
| Cash and savings in all accounts | $24,000 |
| Gold and shares at market value | $8,000 |
| Zakatable assets | $32,000 |
| Credit card balance due this month | −$1,500 |
| Car loan: next 12 months of capital repayments | −$3,600 |
| Mortgage: next 12 months of capital repayments | −$9,000 |
| Net zakatable wealth | $17,900 |
| Zakat at 2.5% | $447.50 |
If $17,900 is at or above the nisab on that day (the value of 85 grams of gold or 595 grams of silver), zakat is due. Without any deduction, the same person would pay $800. Deducting the entire $180,000 left on the mortgage would wrongly bring the figure to zero. Use your own nisab figure on the day; our guide to the 2026 nisab in gold and silver explains how to choose.
Should I deduct my debt even if I can afford to pay it?
Many scholars say you are permitted to, but you do not have to, and some encourage you not to. The National Zakat Foundation, for example, advises that if paying zakat would not affect your ability to repay your debt, the deduction ideally should not be made, or at most one month of payments should be deducted (NZF). The reasoning goes back to why the deduction exists: to stop zakat from pushing someone into hardship with their creditors.
There is also a practical point. When a scholarly difference exists, paying the larger amount is the cautious choice, and any extra still counts as charity. Paying the smaller amount, if you meet the conditions, is a valid choice too.
What about money other people owe me?
That is the other side of the same ledger. Money owed to you that you genuinely expect to be repaid is generally counted as part of your zakatable wealth, either every year or when you receive it, depending on the school. Money you do not expect to see again is usually not counted until you actually recover it. Our guide to zakat on salary shows where these receivables fit in the full list of zakatable assets.
Common mistakes with debt and zakat
- Deducting the full mortgage or student loan balance. This is the most common error, and it can wipe out a real zakat obligation.
- Deducting interest. Only the capital portion of repayments can count.
- Counting future bills that are not yet owed. Next year's rent or school fees are not debts on your zakat date.
- Forgetting debts owed to you. Loans you made to family or friends usually belong on the asset side.
- Losing track of what is actually due. You cannot deduct the next twelve months of repayments if you do not know what they are.
How do I keep this simple every year?
The calculation is easy once you have two lists in one place: what you own and what you owe, each with an up-to-date balance and payment schedule. Most people struggle with zakat not because the rules are hard, but because their numbers are scattered across banks, apps and paperwork.
WiseEnding keeps that record for you. Your accounts, gold and investments sit on one side; the Debt Anchor tracks every debt with its balance and payment plan on the other. On your zakat date you can see what is due within the year, apply the method you follow, and keep a note of what you paid. The same record also helps your family. If you die before a debt is cleared, it shows them exactly what is owed and to whom, so nothing is missed and no one is wronged. Our guide to what happens to debt when you die explains why that matters.
This article is general information, not a fatwa. Scholars differ on debt and zakat, so if you are unsure, ask the scholar or institution you normally rely on.
Frequently asked questions
Is debt deducted from zakat? Under most schools, some debt is deducted before calculating zakat. The common modern approach lets you subtract debts due within the coming lunar year, including the next twelve months of loan instalments. The Shafi'i school, in its best-known view, does not deduct debt at all.
Can I deduct my mortgage from zakat? Not the full balance. Most contemporary scholars allow you to deduct up to one year of capital repayments, and some allow only the single payment due on your zakat date. Deducting the whole outstanding mortgage is not accepted by almost any contemporary authority.
Can I deduct interest from my zakat calculation? No. Interest is never deductible. If a loan carries interest, only the capital part of the repayments due in the coming year may be subtracted from your zakatable assets.
Do I have to deduct my debts before paying zakat? No. Deducting debts is a permission, not a requirement. Some zakat bodies, including the UK's National Zakat Foundation, encourage people who can comfortably repay their debts not to deduct them, or to deduct only one month of payments.
Is a student loan deducted from zakat? Generally only the repayments actually due in the coming year can be considered, and for income-linked loans many people owe little or nothing in a given year. The full outstanding balance is not deducted. Check the method followed by your scholar or zakat body.
