What is a Stocks and Shares ISA?

A Stocks and Shares ISA, also known as a Self-Select ISA or Investment ISA, is a savings account that lets you invest your money and avoid paying UK income or capital gains tax.

Once you've opened an account, you can choose to invest in funds, shares, bonds, and other types of investments. You can withdraw your money whenever you need to, and you can contribute up to £20,000 a year - this is the maximum ISA annual allowance.

  • It can beat cash: Although not guaranteed, investing in the market has historically driven much greater profit than keeping money in a savings account or a cash ISA.
  • Freedom to choose where your money goes: From stocks and shares to funds, trusts, ETFs, government and corporate bonds and more. A stocks and shares ISA lets you access a huge range of investment opportunities. You can even invest in line with your beliefs and values through ethical and sustainable ISA portfolios.
  • Inheriting an ISA is easy: Your spouse can inherit your stocks and shares ISA if you pass away, they would receive the value of your account as an additional one-off allowance.

How much can I invest in an ISA?

You can save up to £20,000 every tax year (6 April to 5 April) - this is known as your Annual Allowance.

If you contribute more then you may have to pay tax on your investments.
