Calculating Zakat when you hold a mortgage is one of the most common questions UK Muslim homeowners ask. This guide reflects the current UK scholarly consensus (2026), including updated positions on offset and Islamic home-purchase plans, and uses the live UK Nisab figures: Gold £8,436 · Silver £987 (updated 2 June 2026).

The General Principle: Debts And Zakat
All immediately due debts can be deducted from your Zakatable wealth. If your immediate liabilities exceed your qualifying assets, no Zakat is due. If a balance remains above the Nisab (currently £987 using the recommended Silver standard), Zakat is paid at 2.5% on that net figure.
Long-term debts — such as a 25-year mortgage — are not deducted in full. The classical Hanafi position (cited from Imam al-Kasani) and the modern majority view across UK scholarship agree that only the portion of the debt that is currently due reduces your Zakatable wealth.
Conventional (Interest-Based) Mortgages
Interest (Riba) is forbidden, and the encouragement is always to exit a Riba-based contract as quickly as possible. For Zakat purposes, the outstanding mortgage balance is not subtracted from your assets. The widely cited UK scholarly allowance is that you may deduct up to twelve months of the upcoming capital (non-interest) payments — and only if not doing so would meaningfully impair your ability to keep paying on time.
Islamic Home Purchase Plans (Ijara, Murabaha, Diminishing Musharakah)
Shariah-compliant home finance from providers such as Al Rayan or Gatehouse is structured as rent-to-own (Ijara) or co-ownership (Diminishing Musharakah). The current UK consensus (NZF, AMJA) treats these the same way as a conventional mortgage for Zakat purposes: deduct only the next twelve months of capital/acquisition payments, not the entire outstanding plan balance.
Offset And Flexible Mortgages (Updated Guidance)
Post-2023, several UK scholars have clarified the position on offset mortgages: the savings sitting in your offset account are still your wealth and are fully Zakatable, even though they reduce interest charged. The fact the bank is using them to offset a Riba-based liability does not remove your ownership or the obligation of Zakat on them. Pay 2.5% on the offset balance as you would on any other savings.
Second Homes And Buy-To-Let
A second property held purely as a long-term investment, with no firm intention to sell, is not itself Zakatable. However:
- Rental income retained on your Zakat anniversary is Zakatable at 2.5%.
- If you intend to sell the property, the sale proceeds become Zakatable in the year you receive them.
- Property bought with the primary intention of resale (flipping) is treated as trading stock — its market value is Zakatable each year.
Worked Example
Savings £12,000 · Outstanding mortgage £180,000 · Next 12 months’ capital portion £6,000. Zakatable wealth = £12,000 − £6,000 = £6,000. That is above the Silver Nisab (£987), so Zakat owed = £6,000 × 2.5% = £150.
Frequently Asked Questions
Can I deduct my entire mortgage balance?
No. UK scholarly consensus permits deducting only up to twelve months of upcoming capital payments, not the full outstanding balance.
Is the savings balance in my offset mortgage Zakatable?
Yes. You retain ownership of those funds, so they remain Zakatable at 2.5%.
Are Islamic home finance products treated differently?
Currently no — the UK consensus is to apply the same twelve-month deduction rule as for conventional mortgages.
Do I owe Zakat on the equity in my home?
Your primary residence is not Zakatable, regardless of how much equity you hold.
