What is an Investment (Stocks and Shares) ISA?

An Investment ISA (also known as Stocks and Shares ISA) is a tax-efficient account meaning you don’t pay UK income or capital gains tax on any returns you make. It’s a flexible way to grow your money, allowing you to invest in shares, funds, bonds and more. Investments could also provide higher returns than cash over the long term.

Tax-efficient investment

You don’t pay UK income tax or capital gains tax on any returns you make from your investments in a Stocks and Shares ISA.

Trusted by millions

Over 37m Stocks and Shares ISAs have been used since 2008 with the aim to grow your money tax-free.

Flexible withdrawals

You can withdraw cash at any time and top back up before the end of the tax year without affecting your annual ISA allowance.

Wide investment choice

You can invest in UK and overseas shares, bonds, funds, Exchange Traded Funds (ETFs) and investment trusts within a Stocks and Shares ISA.

The value of investments can fall as well as rise so you may get back less than you invest. Tax rules can change and their effects vary depending on your individual circumstances. Please check the costs involved before transferring.

Investing could grow your money more than savings

Over the 5-year period from 1 January 2020 to 31 December 2024 holding money in a savings account would have produced different returns to investing in Ready-made Investments. The graph below shows the performance over this period of our Barclays Everyday Saver compared to investing in each of our Ready-made Investments funds. You should also bear in mind that the past performance is not an indicator of future performance.

Graph showing returns of various products over 5 years.

The graph shows a starting investment of £10,000 on 1 January 2019 and the return provided over 5 years for the Everyday Saver account versus the five Ready-made Investment funds. At the end of the 5 year period Barclays Everyday Saver would have provided a return of £10,302, Ready-made Investment Defensive £10,856, Ready-made Investment Cautious £11,716, Ready-made Investment Balanced £13,022, Ready-made Investment Growth £14,095 and Ready-made Investment Adventurous £15,095.

Important information – This is one example and there are different savings and investment products available which would have earned different returns. Barclays Everyday Saver is an easy access savings account and there are other savings options available with us that could earn you a higher return. Returns are not the same each year and in some years savings can outperform investments. Returns include compound growth where income is re-invested and have been calculated before fees and charges which after being applied would lower fund performance. All comparisons exclude inflation.

Learn more about our Investment (Stocks and Shares) ISA

ISA stands for Individual Savings Account.

Any money invested through an ISA is free from UK Income and Capital Gains Tax. Plus there is no need to declare these investments or the gains or income they produce on your tax return. The government sets the maximum ISA allowance – which is £20,000 for this tax year.

It starts on 6 April and ends on 5 April each year. If you do not use your full ISA allowance each tax year it is lost forever.

You can split your £20,000 annual ISA allowance across different ISAs. So, for example, you could put £15,000 into a Stocks and Shares ISA and £5,000 into a Cash ISA in the same tax year for example. You can also open and invest in multiple Investment (Stocks and Shares) ISAs within the same tax year.

Yes. Simply open a Smart Investor account and request an ISA transfer online. Just tell us where you are transferring from and what you want to transfer, and we will do the rest of the transfer legwork.

You can open and start investing in a Barclays Investment (Stocks and Shares) ISA from as little as £50.

Yes, you can withdraw available cash from your Investment ISA at any time without penalties.

We have over 8,000 investments you can choose from, or if you’re short on time, select a Ready-made Investment and leave the rest to us.
