Do I Pay Zakat on My ISA? Cash ISA, Stocks ISA, and Lifetime ISA Explained

Individual Savings Accounts (ISAs) are one of the most popular savings vehicles in the UK, with millions of Muslims saving through them. But the ISA's tax-free wrapper creates a common source of confusion: does the ISA account type affect whether Zakat applies?

The short answer is no — the ISA wrapper is a UK tax designation and has no bearing on Islamic law. Zakat is assessed on the underlying assets, not the account type they are held in.

The Core Principle

Zakat applies to your wealth, regardless of where it is held. A savings account, an ISA, a safe at home, or a wallet on your phone — the container does not determine whether Zakat is due. What matters is:

You own the wealth
It exceeds the nisab threshold
A full lunar year (hawl) has passed

The UK government's tax treatment of your savings is irrelevant to this analysis.

Cash ISA

A Cash ISA is simply a savings account with a tax-free interest wrapper. For Zakat purposes:

The cash balance is fully Zakatable — it is no different from money in a regular savings account
The interest (if any) may raise a separate question about permissible earnings, but for Zakat purposes, include the full balance
Apply 2.5% to the Cash ISA balance as part of your overall Zakatable wealth calculation

Example:

Cash ISA balance: £12,000
Regular savings: £3,500
Total cash savings (Zakatable): £15,500
Zakat (assuming total wealth exceeds nisab): £15,500 × 2.5% = £387.50

Stocks and Shares ISA

A Stocks and Shares ISA holds investments — usually a combination of equities, ETFs, bonds, and funds — in a tax-efficient wrapper.

For Zakat:

The investments within the ISA are Zakatable, just as they would be outside the ISA
Use the market value of your portfolio on your Zakat calculation date (this is the most commonly adopted approach among contemporary scholars)
If you follow the underlying assets approach (looking through shares to liquid balance sheet items), that methodology applies equally whether shares are held inside or outside an ISA

Example:

Stocks and Shares ISA portfolio value: £28,000
Zakat at 2.5%: £700

What About Bonds and Fixed Income?

Conventional bonds — which pay a fixed interest coupon — are generally considered impermissible under Islamic finance principles. If your ISA holds conventional bonds, you may wish to consult a scholar about both the permissibility of the investment and its Zakat treatment. Sukuk (Islamic bonds) are treated as trade assets and are fully Zakatable at market value.

Lifetime ISA (LISA)

The Lifetime ISA is a government-backed scheme for first-time buyers or retirement saving, offering a 25% bonus on contributions up to £4,000 per year.

Zakat considerations:

The balance (including government bonus) is Zakatable, as it is wealth you own and can (eventually) access
The government bonus is part of your wealth — include it in your Zakatable total
There is a 25% withdrawal penalty if you access the LISA before age 60 (outside of a first home purchase). Some scholars argue this reduces the "accessible" value and would deduct the effective penalty from the Zakatable amount. This is a minority view; the majority would include the full balance.

Example:

LISA balance (including bonus): £8,500
Include in full in Zakatable wealth calculation
Zakat at 2.5%: £212.50

Junior ISA (JISA)

A Junior ISA is held in a child's name and cannot be accessed until the child turns 18.

This is one of the more nuanced ISA types for Zakat:

The JISA belongs to the child, not the parent — Zakat follows the owner
A pre-pubescent child is not yet obligated to pay Zakat (there is scholarly disagreement on this point; the Hanafi school holds children are not obligated, while the Maliki and Shafi'i schools hold that a guardian must pay Zakat on a child's behalf)
If you follow the Maliki or Shafi'i opinion: include the child's JISA in the Zakatable calculation and pay 2.5% from the child's assets (or from your own wealth on their behalf)
If you follow the Hanafi opinion: Zakat is not yet due on a child's JISA; it becomes due once the child reaches maturity and their own hawl completes

Help to Buy ISA (Closed to New Applicants)

If you hold a legacy Help to Buy ISA (no longer open to new applications), treat it the same as a Cash ISA — include the full balance in your Zakatable wealth.

Putting It All Together

Here is an example of a UK Muslim with multiple ISA types:

| Asset | Value | Notes | |---|---|---| | Cash ISA | £14,000 | Fully Zakatable | | Stocks & Shares ISA | £31,500 | Market value, fully Zakatable | | Lifetime ISA | £9,200 | Include full balance | | Junior ISA (child's) | £4,800 | Hanafi: exempt; Shafi'i/Maliki: Zakatable | | Regular savings account | £2,100 | Fully Zakatable | | Short-term debt owed | −£1,500 | Deductible |

If following Hanafi (child's JISA excluded): Total Zakatable = £14,000 + £31,500 + £9,200 + £2,100 − £1,500 = £55,300 Zakat due = £55,300 × 2.5% = £1,382.50

If following Shafi'i/Maliki (child's JISA included): Total Zakatable = £55,300 + £4,800 = £60,100 Zakat due = £60,100 × 2.5% = £1,502.50

Nisab Check

Before paying Zakat, confirm your total Zakatable wealth exceeds the nisab:

Gold nisab (2026, GBP): ~£4,200–£4,500
Silver nisab (2026, GBP): ~£380–£420

In the example above, £55,300 is well above either threshold — Zakat is clearly due.

The Simple Rule to Remember

ISA = tax wrapper only. For Zakat, look through the wrapper to the underlying asset.

Cash → include balance
Stocks → include market value
Government bonus → include with balance
