What is an investment ISA?

Also known as a stocks and shares ISA, it’s your simple, tax-free investment account.

Invest your savings

You might’ve seen it called a stocks and shares ISA with other providers, but it’s the same thing: an individual savings account (ISA) that lets you invest what you save, giving you the opportunity to grow it.

Without paying tax!

An investment ISA has tax benefits. You can add up to £20,000 to it each year, and the investments you buy can grow and earn income, tax free! ISAs are an investor's friend but remember, tax and ISA rules could change in future.

For the full details of the Dodl investment ISA, make sure you read its key features.

    While investing with Dodl is…a doddle, it carries risk. The value of your investments can go down as well as up and you could end up with less than you put in.

    Investment ISA charges

    Like all Dodl accounts, you'll only pay one simple low-cost charge for your investment ISA. Here's how it works.

    How much?

    0.15% of the value of your investments per year (min £1 per month)

    How will I pay it?

    It’s collected from the available cash in your investment ISA once a month, so it’s spread over the whole year.

    Anything else?

    The investments you choose have their own charges to buy/sell or hold them.

    It's important to know

    You have to be a UK resident for tax purposes to open an account with Dodl.

    The past performance of investments isn't an indicator of their future performance and their value can go down as well as up. This means you could get back less than you originally invested. 

    Dodl doesn’t offer any advice so if you’re not sure about the risks involved with investing, you should speak to a suitable financial adviser. 

    How you're taxed depends on your circumstances, and tax rules can change in future.
