Stocks & Shares ISA

A Stocks & Shares ISA can be a great way to grow your savings and protect them against tax. We offer three different types of account to suit your needs.

What is an ISA?

ISA stands for ‘Individual Savings Account’. They enable people to put money away, whether that be as cash or investments, without having to pay any further income tax or any capital gains tax on any profits made. ISAs were introduced in 1999 as a way for the general public to receive a tax break on their savings. ISAs do not have to be reported on tax returns, and most of the time, you can withdraw your money whenever you need to.

Adult ISAs are available in four different forms; Stocks & Shares ISA, Cash ISA, Innovative Finance ISA and Lifetime ISA.

Investing in a Stocks and Shares ISA over the long-term could end up giving you a higher return than a Cash ISA. They allow your investments to grow with the market rather than offering a flat rate on returns. Bear in mind though that investing does bring additional risk as investments can fall as well as rise meaning that you may get back less than you invested.

Choose your ISA

How to choose your annual growth rate
Your ISA's annual growth rate will depend on what type of investments you choose. In general, the more risk you are prepared to accept, the higher your potential returns.

For your convenience, our recommended shares to buy and Platinum 120 finest funds are each given a risk rating: lower, medium or higher risk. Although past performance is not an indicator of future performance, have a look at how some of these shares and funds have performed on an annual basis. It'll give you an idea of what annual growth rate you could aim for.

How our stocks and shares ISA calculator works
Our ISA interest calculator is based on our Self-select Stocks & Shares ISA, and account fees are deducted as part of the calculation. Dealing commission is not deducted, since it depends on how many investments you buy and sell. Similarly, future ISA allowances can't be taken into consideration since any increases are announced on an annual basis.

Projected investment growth shown by our ISA calculator is just an indication of how your money could grow. Actual growth will depend on your investments' performance.

What do I need to get started?

All you need to get started are your National Insurance Number and your bank account details. Just select which ISA you'd like, enter a few details and you can be investing in no time.

How much can I invest in my ISA?

For the 2020/21 tax year, running from 6 April 2020 until 5 April 2021, the ISA Allowance is £20,000. For Lifetime ISAs, you are only able to pay in a maximum of £4,000 this tax year, although this forms part of your overall annual ISA limit.

Each year, the Government sets an ISA allowance; the maximum amount of money that can be paid into an ISA during that tax year (6th April to 5th April the following year). You have up until the close of business hours on 5th April each year (usually 6pm) to pay into an ISA for that tax year. From 6th April, the new tax year begins and any allowance that has gone unused won’t carry over to the next year.


If you’re a UK resident, you can have an ISA. You need to be 16 years old to open a Cash ISA and 18 years old to open a Stocks and Shares ISA, Lifetime ISA or an Innovative ISA. You can only open an ISA in one name, so it isn’t possible to open a Joint ISA and generally speaking, you cannot open an ISA for someone else.

Each tax year, you can spread your ISA allowance across the four different types of ISA (Cash, Stocks & Shares ISA, Lifetime and Innovative Finance) but you can only pay into one of each type per tax year. So you can have up to four ISAs each tax year.

When paying into multiple types of ISA in a tax year, they don’t all have to be with the same provider. You can have a Cash ISA with a bank and also pay into a Stocks & Shares ISA with a stockbroker. And once the tax year ends, you aren’t limited to just using the same providers. You can open accounts for the new tax year with someone else, and either leave your old ISAs where they are or transfer them across to your new provider.

We have become part of interactive investor. As a result, you can no longer transfer an ISA to us.
