An ISA (Individual Savings Account) is a tax efficient way to save or invest. Unlike other savings accounts you don’t pay tax on money held in an ISA, regardless of your balance or how much income tax you pay.

The government sets an allowance for each tax year which states the maximum you can save tax-free. Each tax year runs from 6 April to 5 April the following year. The ISA allowance for the 2023/2024 tax year is £20,000 and £9,000 for Junior Cash ISAs.

  • Cash ISAs will take no more than 15 working days to transfer.

  • Stocks and Shares ISA or innovative finance ISAs will take no more than 30 days to transfer. To transfer an innovative finance ISA you will need to pop into branch.

  • You cannot transfer a Lifetime ISA to us.

Remember, if you withdraw money from a previous ISA with another provider, you will need to replace the withdrawn money before you transfer it to us. Otherwise you will no longer be able to repay that money in to your ISA, and it won't be tax-free.

You must be a UK resident and 16 years old or over to open a Cash ISA. Under 18s can apply for a Junior Cash ISA.

If you already have an existing TSB Cash ISA, you can top it up via:

  • Internet Banking - select the account you want to make the payment from and then select "Make a transfer"
  • Mobile banking app – tap “Move money” and then follow the steps
  • Telephone Banking (automated service) - when prompted, say or select “transfer money”. View our guide to Telephone Banking
  • In a branch

Some customers may be prevented initially from adding money to their existing cash ISAs from 6 April. This is due to the Government’s requirement to request that customers agree a new ISA declaration if they did not add money to their cash ISA in the previous tax year. It’s easy to reactivate your cash ISA. Simply log in to Internet Banking, select the cash ISA you want to add money into, click reactivate and follow the online instructions.

If you have a Fixed Rate Cash ISA that’s coming to an end, then there are a few options that you can pick from. Visit our Fixed Rate Cash ISA maturity page.

Please visit our account closure page for more information.

If your ISA provider isn't listed in the dropdown list of TSB's ISA transfer form, this means we cannot accept your ISA transfer instruction using this method. If you want to continue to transfer your ISA to TSB, please download, print and complete the ISA Transfer Authority form.
