Why invest in a Stocks & Shares ISA?

A Stocks and Shares ISA (Individual Savings Account) could potentially give you better returns than a traditional savings account, although this can't be guaranteed.

Investments within an ISA are protected from UK income tax and Capital Gains Tax. You can also access your money at any time.

How much can I invest in an ISA?

You can contribute up to £20,000 a year - this is your 2021/22 Annual Allowance - in either a single ISA or spread over several different types of ISA.

Tax rules and benefits can vary depending on your circumstances.

Why investors love ISAs

Investors love ISAs because they are simple and flexible. But with interest rates at record lows, a Stocks and Shares ISA provides a better opportunity than cash to grow your money over the long term – although this can’t be guaranteed.

Once stashed inside an ISA, your investments are sheltered from capital gains and dividend taxes, and you can take the money out at any time free of tax too.
