ISA
An Individual Savings Account: a UK tax wrapper where interest, dividends and gains are free from UK tax, up to an annual allowance.
In plain English
An ISA is not an investment itself. It is a “wrapper” you can hold cash or investments in, so that any interest, dividends or gains are free from UK tax.
There are several types, including Cash ISAs, Stocks and Shares ISAs, Lifetime ISAs (for a first home or retirement) and Junior ISAs. Adults in the UK have an annual allowance across their ISAs, currently £20,000.
An everyday example
If you invest in a fund inside a Stocks and Shares ISA and it grows, you pay no UK capital gains tax when you sell, and no tax on dividends it pays. The same investment outside an ISA could be taxed.
Why it matters for investors
Using an ISA can make a meaningful difference to long-term returns, especially combined with compounding. ISA rules and allowances can change, and the right type depends on your circumstances. Investments in a Stocks and Shares ISA can still fall in value.
