Investing doesn't have to be taxing
Discover everything a UK investor needs to know about tax, with added insight from our experts.
Important information: As investment values can go down as well as up, you may not get back all of the money you invest. Currency changes affect international investments, and this can decrease their value in sterling. If you’re unsure if an investment account is right for you, please speak to an authorised financial adviser. Tax treatment depends on your individual circumstances and may be subject to change in the future.
"It’s important to choose the right investment for you, but it’s just as important to understand how the many different taxes can affect your wealth.
It doesn’t matter how much you’re investing, knowing the range of tax allowances available can help you significantly improve your finances and future outcomes, from pensions, ISAs and savings to dividends and capital gains."
