Halal ISA UK: Is an ISA Halal? Cash, Stocks and Shares, Lifetime and Junior ISAs Explained

For Muslim savers and investors in the UK, a common question is whether an ISA is halal at all, and if so, which kind.

The short answer: an ISA (Individual Savings Account) is a tax wrapper, not an investment. The wrapper simply means UK tax is not charged on the returns inside it. Most scholars and Islamic finance bodies regard the wrapper itself as neutral. What decides whether a particular ISA is Shariah compliant is what sits inside it: interest-bearing cash is not, while profit-based Islamic savings and Shariah-screened shares or funds are commonly regarded as permissible.

Below: each ISA type, how the halal versions work, and the rule changes starting in April 2027.

Why the ISA wrapper itself is not the issue

An ISA is a set of HMRC rules. If money is held inside an ISA, interest, profit, dividends and capital gains on it are free of UK income tax and capital gains tax. Each adult has an annual allowance of £20,000, which can be split across the different ISA types.

Because the wrapper is just a tax treatment, the Shariah questions are the same ones that apply outside an ISA:

• Does the money earn interest (riba)? A conventional cash ISA pays interest, which is why it is not regarded as Shariah compliant.
• What is the money invested in? A stocks and shares ISA can hold anything from Shariah-screened funds to bank shares, tobacco companies and bond funds.
• What happens to uninvested cash? Some platforms pay interest on spare cash inside a stocks and shares ISA, often as an opt-in setting.

So "halal ISA" really means an ISA whose contents are structured or screened to meet Shariah principles.

The four ISA types at a glance

Islamic cash ISAs

A conventional cash ISA pays a fixed or variable interest rate on deposits. Islamic banks in the UK offer cash ISAs that pay an expected profit rate instead. The bank uses deposits in Shariah-compliant financing and trade activity, and the saver receives a share of the profit generated. The rate is called "expected" because, in principle, it is not guaranteed in the way interest is, although in practice UK Islamic banks have a long record of paying the rate they advertise.

In the UK, Islamic cash ISAs are currently offered mainly by Gatehouse Bank and Al Rayan Bank, in both easy access and fixed term versions. These banks are authorised by the Prudential Regulation Authority, and eligible deposits are covered by the Financial Services Compensation Scheme up to £120,000 per person, per banking licence.

Expected profit rates change often, so any figure in an article goes out of date quickly. The banks' own websites publish their current rates. For a wider look at how profit-based accounts work, see our guide to Islamic savings accounts in the UK.

Some scholars and commentators question how different expected profit rates are from interest in practice, since they tend to track the Bank of England base rate. The mainstream position, reflected in the Shariah boards that approve these products, is that the underlying contracts are what matter, and that these contracts are valid.

Halal stocks and shares ISAs

A stocks and shares ISA holds investments rather than savings. This is where most long-term halal investing in the UK takes place, and there are three common routes.

1. Ready-made Shariah portfolios

Some providers offer managed portfolios that are built entirely from Shariah-screened assets and overseen by a Shariah board. These typically offer several risk-graded portfolios made up of Islamic equity funds, sukuk and sometimes gold. Fees on managed services are typically higher than self-selected funds.

2. Shariah index funds and ETFs on a general platform

Mainstream platforms let ISA holders buy Shariah index funds and ETFs. Examples include the HSBC Islamic Global Equity Index Fund (a traditional fund) and Islamic ETFs such as the iShares MSCI World Islamic ETF. These track indices that have already applied Shariah screens. Costs are often lower than managed portfolios, though platform fees vary.

Shariah screening and ethical screening are not the same thing. A fund can pass Shariah tests and still hold companies that some Muslim investors avoid for other reasons, such as links to occupation or arms. We looked at this in HSBC funds complicit in genocide?

3. Choosing individual shares

Some investors build their own ISA portfolio from individual companies, often on low-cost apps. In that case each company needs to pass two kinds of test:

• Business activity: no core business in alcohol, gambling, conventional finance, pork, adult content and similar areas.
• Financial ratios: under AAOIFI Shariah Standard 21, interest-bearing debt is commonly capped at 30% of market value, and income from impermissible sources at 5% of total income, with that small portion purified through charity.

Companies can drift in and out of compliance, as explained in what happens when your halal stock turns non compliant. For one popular platform, our guide Is Trading 212 halal? covers its ISA, interest on cash and share lending in detail.

Interest on uninvested cash

Several platforms pay interest on cash sitting uninvested in a stocks and shares ISA. Where this is an optional setting, the usual approach among Muslim investors is to leave it switched off. Where it cannot be switched off, many investors keep cash balances low and give any interest received to charity without the intention of reward, which is the common scholarly position on purification.

Halal Lifetime ISAs

The Lifetime ISA (LISA) is open to people aged 18 to 39. Up to £4,000 a year can be paid in, and the government adds a 25% bonus, worth up to £1,000 a year. The money can be used for a first home costing up to £450,000 or taken from age 60. Other withdrawals face a 25% charge.

The government bonus is commonly regarded by scholars as a permissible grant rather than interest, because it is not a return on a loan. The Shariah question is therefore about how the LISA is invested. A cash LISA from a conventional provider pays interest, so Muslim savers usually look at stocks and shares LISAs with a Shariah fund option. A small number of UK providers offer a Shariah Lifetime ISA invested in an Islamic global equity fund, and charges vary between them.

A change is on the way. The government has consulted on replacing the LISA with a new First Time Buyer ISA, focused only on buying a first home, with the bonus paid at purchase and no withdrawal charge proposed. The consultation closed in August 2026. At the time of writing, a launch date, bonus rate and contribution limit have not been confirmed, and existing LISA holders are expected to be able to keep their accounts under current rules.

Halal Junior ISAs

A Junior ISA lets parents and family save up to £9,000 a year for a child, with the money locked until the child turns 18. The government has frozen this limit until April 2031.

Shariah options include stocks and shares Junior ISAs invested in Islamic funds.

What changes in April 2027

From 6 April 2027, the overall ISA allowance stays at £20,000, but:

• Cash ISA limit: savers under 65 will only be able to put £12,000 a year into cash ISAs. The remaining £8,000 can still go into stocks and shares or other ISA types. Savers over 65 keep the full £20,000 cash allowance, according to HM Treasury.
• Interest on cash in stocks and shares ISAs: interest paid on uninvested cash will face a 22% charge. For Muslim investors who already keep this setting off, this makes no practical difference.
• Transfers: savers under 65 will no longer be able to transfer money from a stocks and shares ISA into a cash ISA.

The cap applies to Islamic cash ISAs in the same way as conventional ones, because the limit is set by the wrapper, not the product. Savers who currently put their whole allowance into an Islamic cash ISA will have less room for profit-based savings from 2027/28.

Frequently asked questions

Is an ISA halal?

An ISA is a tax wrapper, so most scholars regard it as neutral. An ISA is commonly regarded as halal when its contents are Shariah compliant, such as an Islamic bank cash ISA or a stocks and shares ISA holding screened investments.

Is a cash ISA haram?

A conventional cash ISA pays interest, which is riba, so it is not regarded as Shariah compliant. Islamic cash ISAs from banks such as Gatehouse and Al Rayan pay an expected profit rate instead and are approved by their Shariah boards.

Is a stocks and shares ISA halal?

It depends on the holdings. Shariah-screened funds, Islamic ETFs and individually screened shares are commonly regarded as permissible. Bond funds, conventional bank shares and interest on uninvested cash are not.

Is the Lifetime ISA bonus halal?

The 25% government bonus is commonly regarded as a permissible grant, since it is not a return on lending. Scholars focus on how the LISA itself is invested.

Is there a halal Junior ISA?

Yes. Stocks and shares Junior ISAs invested in Islamic funds are available, and some platforms allow Shariah funds inside a Junior ISA.

Do I pay zakat on my ISA?

Zakat applies to wealth whether or not it sits in an ISA. Scholars differ on the method for shares and funds, for example full market value or the zakatable assets of the underlying companies.

Will the 2027 changes affect Islamic cash ISAs?

Yes. The £12,000 cash ISA limit for under-65s applies to all cash ISAs, including Islamic ones, from 6 April 2027.

Taking it further

Choosing the wrapper is the easy part. The harder questions are what to hold inside it and how it fits a wider plan.

• The Nisba Halal Screener screens funds for Shariah and BDS compliance and can export a ready-made pie to Trading 212, which many people use inside a stocks and shares ISA.
• The Nisba Academy is a one-month course built around a six-step framework for halal investing, from goals and ISAs through to choosing investments, with a money back guarantee.
