Keep up to £3,400* more of your returns per tax year

A higher-rate taxpayer could save up to £3,400 in taxes annually by investing in a Stocks and Shares ISA instead of a taxable account. With an ISA, all gains and dividends are completely tax-free, so you keep more of what you earn and maximise your returns. Capital at risk.

*Calculated based on the £3,000 annual capital gains exemption, higher-rate taxpayers are taxed at 20% on gains above this threshold. This means that on a £20,000 investment gain outside an ISA, you would pay £3,400 in capital gains tax (20% of £17,000). However, inside an ISA, all gains are completely tax-free, allowing you to keep the full amount.

Powered by core low-cost investments

Combine Global Stocks and Global Bonds within a single Stocks and Shares ISA to get a clear view of your total investment value and remaining ISA allowance. Track performance across all portfolios or drill down into individual ones - all in one place.

Please remember, investing should be viewed as longer term. Your capital is at risk - the value of investments can go up and down, and you may get back less than you put in.
