Is a Stocks and Shares ISA halal?

The wrapper is neutral

An ISA (Individual Savings Account) is a UK tax rule, not a product. It simply means you don't pay tax on gains or dividends from what you put inside it, up to a yearly allowance. Islam has no problem with a legal tax break. So the question isn't "Is an ISA halal?" but "Is what I'm buying inside it halal?"

That's why the same ISA provider can be halal for one person and not for another, depending on what each person picks. The general rules for owning shares are explained in Can I invest in stocks as a Muslim?

What to hold inside it

• Shariah-screened funds or ETFs: these filter out companies whose main business is haram (alcohol, gambling, conventional banking, pork, adult content) and companies carrying too much interest-based debt. Most scholars accept this approach, and many funds have a Shariah board that also purifies small amounts of non-compliant income.
• Individual halal shares: fine if you screen them yourself or use a screening app.
• Avoid: government and corporate bond funds (gilts), money market funds and default "cautious" portfolios, which usually hold interest-bearing assets.

Watch the cash sitting in your account. Many platforms pay interest on uninvested cash. Keep cash low, or give any interest you receive away. See What do I do with interest money from my bank account?

Cash ISAs and the Lifetime ISA

A regular Cash ISA pays interest, so most scholars say to avoid it. Some UK Islamic banks offer a Cash ISA that pays an "expected profit" from Shariah-compliant deals instead of interest; scholars generally accept these as an alternative.

The Lifetime ISA (LISA) adds a government bonus on what you save for a first home or retirement. Most scholars see the bonus as a government grant, not riba, because it isn't interest on a loan to the government. The same rule still applies: hold it in a stocks-and-shares LISA with halal funds, or with an Islamic bank's version, rather than a standard interest-paying one.

What to check before you invest

Look at the fund's factsheet for a Shariah board or screening index, check what happens to cash in the account, and read the charges. Once your ISA grows past the nisab threshold, zakat may be due on it. See Do I pay zakat on stocks?
