* Calculated based on the £3,000 annual capital gains exemption, higher-rate taxpayers are taxed at 24% on gains above this threshold. For example, on a £20,000 investment gain outside an ISA, you would pay £4,080 in capital gains tax (24% on £17,000, after applying the £3,000 exemption). However, inside an ISA, all gains are completely tax-free, allowing you to keep the full amount. Tax rules and rates may change, and the value of investments can go down as well as up, meaning you may not get back the amount you originally invested. Always seek independent financial advice tailored to your individual needs.
The way people invest can create significant disparities. Individuals with high net worth can often optimise their tax situation, diversify their portfolios, leverage assets, and patiently maintain a variety of investments. Our aim is to extend these opportunities to everyone.
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.
Sidekick’s Stocks and Shares ISA allows you to invest in a tax-efficient way, keeping more of what you earn. You can contribute up to £20,000 per tax year, and any returns - whether from dividends, interest, or capital appreciation - are completely free from UK tax.
With Sidekick, you can hold multiple investment types within one ISA, including Global Stocks and Global Bonds. This means you can build a diversified, tax-efficient portfolio tailored to your financial goals.
Your ISA allowance resets every tax year on April 6th, and any unused portion cannot be carried over.
With Sidekick’s ISA, you can invest in:
Global Stocks – Invest in the SPDR MSCI World UCITS ETF, a well-diversified fund tracking the MSCI World Index.
Global Bonds – Gain exposure to high-quality, investment-grade bonds through the Vanguard Global Aggregate Bond UCITS ETF.
These options allow you to build a balanced portfolio while benefiting from tax-free growth.
Sidekick is your gateway to the financial advantages of the ultra-wealthy, offering sophisticated cash management, exclusive investment opportunities, and flexible liquidity solutions - all designed to help you grow and manage your wealth with confidence.
In addition to our Stocks and Shares ISA, Sidekick offers easy access and fixed term savings accounts, and a General Investment Account (GIA).
A GIA allows you to invest beyond the £20,000 annual contributions of an ISA, making it a useful option once you’ve used your annual ISA allowance. Within a GIA we offer additional investment assets, like our Money Market Fund and Custom Index portfolio.
