Cash ISA vs Stocks and Shares ISA

What is a cash ISA?

A cash ISA is a savings account where your money is held as cash and earns interest, similar to a regular savings account. The key difference is that you can contribute up to £20,000 per tax year, and any interest you earn is completely tax-free, meaning you don’t pay UK Income Tax on it.

What is a stocks and shares ISA?

A stocks and shares ISA lets you invest in options like funds, shares and ETFs, offering the same tax-free benefits, but with potential growth based on how your investments perform. Unlike a savings account with a fixed interest rate, the returns on your stocks and shares ISA can vary, so the value of your account can go down as well as up.

Transfer eligibility criteria

To transfer a cash ISA to a stocks and shares ISA, you’ll need to be a UK resident aged 18 or over. Your new provider will take care of the transfer and check your eligibility as part of the process.

It’s important to always use the official transfer process to ensure the tax-free benefits on your savings stay intact throughout.

If you have a cash Junior ISA for your child, you can transfer it to a Stocks and Shares Junior ISAs*. There are slightly different rules for Junior ISA transfers, as a child can only have one of each type.

How does a cash ISA transfer work?

When you request a transfer from a cash ISA to a stocks and shares ISA, the providers carry out your request and move the funds directly from your cash ISA to a stocks and shares ISA. Here is a breakdown of what happens in the background:

1. Follow the transfer process for the stocks and shares ISA you’ve chosen. This may involve filling out a transfer-in form with your current providers’ details and the details of the product you want to take out
2. Your new provider will contact your current cash ISA provider on your behalf to start the transfer process
3. The money is transferred directly from your cash ISA into your new stocks and shares ISA, maintaining the tax-free benefit throughout

You should keep your cash ISA open throughout the process, and your new provider will do the rest for you. In your transfer application, you’ll declare if you want your cash ISA provider to transfer some or all of your fund, into your new stocks and shares ISA. Whichever you choose, this should be carried out as part of your transfer without any further action needed from yourself.

Depending on the processes of your current cash ISA provider, you may need to inform them to either close the account or keep it open after completing the transfer. They will likely be in touch once they receive the transfer instruction to let you know if you need to take any action on your existing cash ISA.

It's important to check the terms and conditions of the new ISA to ensure you're comfortable with any potential change in risk. Transferring from a cash ISA to a stocks and shares ISA increases the level of risk, as your funds will be invested and your capital will be at risk.

ISA transfer rules

Before you start your transfer, it is worth understanding the rules.

Things to consider before transferring to a Stocks and Shares ISA

Moving your savings from a cash ISA to a stocks and shares ISA is a decision that will depend on your own circumstances and goals. There are potential advantages to consider, but it is important to understand the risks too.

Potential advantages

• Over the long term, investing in a stocks and shares ISA can offer higher returns than cash savings. Although growth isn’t guaranteed, and it's important to remember that the value of your investment can go down as well as up.
• Your money stays within an ISA wrapper, so any returns remain free from UK Income Tax and Capital Gains Tax.
• Transferring does not affect your annual ISA allowance. The money you move is not considered a new contribution and isn’t counted against your current tax year ISA allowance.
• With a DIY portfolio, you can choose from a range of investments, including funds, shares, and ETFs, to build your own portfolio. Or, for a more hands-off approach, a managed portfolio allows experts to select and manage investments on your behalf.

Things to keep in mind

• Unlike a cash ISA, the value of a stocks and shares ISA can go down as well as up. You may get back less than you put in.
• Performance will vary depending on market conditions and where your stocks and shares ISA is invested.
• Some providers may have platform and dealing fees which could affect your overall returns, particularly on smaller balances or trades.
• If you think you may need access to your money in the short term, it is worth considering whether a longer-term investment is suitable for your needs.

Tax implications of transferring a cash ISA

One of the reasons people consider transferring a cash ISA to a stocks and shares ISA is to keep their money in a tax-efficient environment while exploring longer-term investment options.

When you transfer using the official process, your tax-free benefit stays intact, meaning any growth or returns within your stocks and shares ISA remain free from UK Income Tax and Capital Gains Tax, just as they were in your cash ISA.

It is worth keeping in mind that:

• The tax-free status only applies while your money remains inside an ISA
• The annual ISA allowance applies to new contributions, not transfers, so moving existing savings will not affect how much you can pay in during the current tax year.

When might someone consider transferring?

There is no right time, and everyone's situation is different. That said, people may consider transferring when:

• They have a long-term savings goal in mind and want their money invested over the long-term.
• They have built up a separate short-term savings and emergency fund and feel comfortable investing some of their ISA savings.
• They are reviewing your finances ahead of a new tax year.
