Flexible Stocks and Shares ISA

You can fund your account using a credit or debit card or by transferring funds from your bank account. We do not accept cheque or cash deposits. Please ensure that any payment you make to fund your account is from a card or account in your name. Any payment from third-party sources will be returned.

A flexible stocks & shares ISA has all the same benefits as a regular stocks & shares ISA, where you can fund up to the annual allowance and use your cash and profits to invest in qualified investments. The added benefit of a flexible ISA is that you’re able to withdraw and redeposit the same amount into the same ISA within the same tax year, without affecting your remaining annual ISA allowance. You can’t withdraw from a classic stocks & shares ISA and redeposit the funds without using up additional allowance.

Your national insurance (NI) number is the identifier used by HMRC to track the ISA allowance used by individual investors. We ask for your NI number to help us with our reporting to HMRC.

You can pay into as many Stocks & Shares ISA, Cash ISA and Innovative Finance ISA as you want. However, you are responsible for not exceeding your annual ISA allowance limit.

The minimum amount you can deposit is £1. You can use your debit card to add funds, but you can’t deposit more than the annual limit for ISAs. To activate an ISA in the current tax year, you’ll need to fund a minimum of £1.

Yes, and you can also transfer a cash ISA and innovative finance ISA. All you have to do is open an account, fill out our in-app transfer form, and we’ll work with your current provider to transfer your investments or cash on your behalf. However, we don't accept the partial transfer of your current year's ISA allowance. It must be the full transfer.

Yes, you can withdraw cash from your CMC Invest flexible ISA account whenever you need it, then put it back again in the same tax year, without affecting your annual ISA allowance.

Our flexible stocks & shares ISA allows customers to withdraw uninvested cash from their account and redeposit in the same tax year. To reflect this in the account for those who may have withdrawn more than they have funded in the current tax year, with contributions made in the previous tax year, we will show the difference as a negative amount.

For example, customer A contributed £15,000 to their flexible ISA in the tax year 22/23, and for tax year 23/24 they have yet to fund towards their £20,000 annual allowance. Instead, they have decided to withdraw £5,000 from their account. This will be displayed in the account as a £25,000 annual allowance left and a -£5,000 allowance used.

Currently, we only offer a flexible Cash ISA and a flexible Stocks & Shares ISA. If you’re interested in us adding other types of ISAs, please let us know using the ‘Send us your feedback’ banner on the home screen in the app.
