Transfer shares to an ISA: at a glance

  • What do I need to know? Transferring shares to an Individual Savings Account (ISA) could help you grow your tax-free savings and investment income.
  • What does it mean for me? Understanding ISA rules can help you make informed financial decisions.
  • Why does it matter? Making use of your ISA allowances can add a valuable tax-free element to a balanced savings and investment portfolio.

According to government data, UK taxpayers recorded £12.1bn in Capital Gains Tax (CGT) payments in the 2023 to 2024 tax year. Using the tax-free allowances you’re entitled to can increase the potential of your savings and earnings.

This includes the £20,000 annual Individual Savings Accounts (ISAs) allowance. You can spread this allowance across Stocks and Shares ISAs, which shield your investments from tax, and Cash ISAs, which let you earn tax-free interest. #

In this guide, you’ll learn how to transfer shares to an ISA, and the rules, limits, and tax considerations that could impact how much you can earn.

Can you transfer shares to an ISA?

In general, you can move your shares into an ISA provided you haven’t used up your annual allowance. This usually involves selling your shares and repurchasing them inside a Stocks and Shares ISA.

You can either do this yourself or use a ‘Bed and ISA’ process if your provider offers this service (more on this later). 

It’s important to be aware of the rules and risks of moving your shares into ISAs to prevent unnecessary costs and make the most of your available allowances.

Manually transferring shares

You can transfer your shares to an ISA manually. This means selling your shares and buying back the same assets in a Stocks and Shares ISA. This process offers flexibility and control over exactly when you sell your shares and reinvest them.

But it’s important to remember HMRC charges Capital Gains Tax on profits you make when selling your shares. You could pay up to 24% CGT as a higher or additional rate taxpayer on profits made over your £3,000 annual allowance.

You can invest up to £20,000 each year into a Stocks and Shares ISA as part of your overall ISA contribution limit. But you’ll pay CGT if gains from the sale of your shares exceed £3,000.

Transfer delays and market risk

Manual transfers often involve a delay between requesting the sale with your investment provider and accessing the funds.

The value of shares changes constantly. This means any delay in acquiring your shares could impact how many you can repurchase.

Bed and ISA

Alternatively, your provider could transfer your shares on your behalf using a Bed and ISA process, also called Share Exchange, if they offer this service. But your provider may charge you fees to use this service (more on this later).

How Bed and ISA works

Your provider sells your shares before immediately purchasing them within a Stocks and Shares ISA. This method is usually quicker than repurchasing shares yourself.

Using the Bed and ISA process can limit costly delays. This means you could start earning tax-free returns on your investments sooner.

ISA limits place an annual cap on the amount you can save, invest, or transfer. So, if your investments exceed the ISA limit, you may want to use this process over a handful of years to gradually shield your investments from unnecessary tax.

Spreading your transfers over multiple years could also allow you to stay within your £3,000 annual CGT allowance.

It’s important to speak with a qualified financial adviser to get guidance on your specific circumstances and whether this approach is right for you.

Costs and limitations when transferring shares to an ISA

The Bed and ISA approach may be efficient for transferring your shares into an ISA, but there are costs associated with the process.

Stamp Duty

HMRC usually charges Stamp Duty at 0.5% on the purchase of UK shares.

You typically pay Stamp Duty when you purchase UK shares within your Stocks and Shares ISA. But you won’t pay Capital Gains Tax when you sell them.

Provider fees

Your investment and ISA providers may charge fees for moving your shares.

If you transfer your shares manually into a Stocks and Shares ISA with a different provider, you may have to pay an exit fee. If you use the Bed and ISA process, you can keep the shares with the same provider or switch providers depending on the arrangement.

You also may have to pay a ‘dealing fee’ when you purchase the shares back in your ISA. Your provider typically calculates the dealing fee as a percentage of the transaction or as a flat fee.

ISA limits

It’s important to remember that the government caps your total tax-free ISA contributions at £20,000 each tax year.

But the Cash ISA contribution limit is set to decrease to £12,000 on 06 April 2027 for those aged under 65. If you’re over 65, the limit will remain at £20,000 per tax year.

Transferring large portfolios over a handful of years can help you minimise CGT and stay within your annual ISA limit.

Transferring shares to a Cash ISA

Transferring shares to a Stocks and Shares ISA allows you to move the same assets into an equivalent tax wrapper. But if you’re looking to transfer the proceeds of your shares into a Cash ISA, the process is slightly different.

Cash ISAs cannot hold shares directly. So, you would need to sell your shares and then deposit the money you make into a Cash ISA. This could trigger a CGT bill if you make more than £3,000 in gains from the sale of your shares each tax year.

Transferring the money from selling your shares into a Cash ISA, instead of reinvesting in a Stocks and Shares ISA, could reduce your risk. This is because shares can sharply increase or decrease in value. Although interest rates can also vary in most types of savings accounts, changes are usually in response to the base rate set by the Bank of England.

Earning tax-free interest could add greater stability to a wider wealth portfolio, especially if you’re saving for retirement.

Frequently asked questions about transferring shares to an ISA

Can you transfer shares without paying Capital Gains Tax?

In some circumstances, yes. The government offers an annual £3,000 Capital Gains Tax allowance. So, you can sell and move shares without paying Capital Gains Tax provided you make less than £3,000 of profit from the sale. Your allowance resets every tax year.

How long does it take to transfer shares to an ISA?

It depends on how you structure the transfer. Using a Bed and ISA process, your investment provider can typically transfer your shares to a Stocks and Shares ISA without significant delays. Exact timelines depend on your provider.

If you choose to sell your shares manually, you’ll have to wait for your sale to settle before you can use the money to purchase the same shares in an ISA. This could take multiple working days.

Transferring shares to an ISA for tax-free earnings

Understanding how to transfer shares into an ISA using available allowances could improve the growth and tax efficiency of your investments.

Saving and investing ISAs can shield your earnings from tax within annual limits. And dividing your contributions between Cash ISAs and Stocks and Shares ISAs can help you develop a balanced portfolio that supports your financial ambitions.
