What is an ISA allowance?

Your ISA allowance is the total amount of money you can save in ISA accounts in the current tax year. An ISA is an Individual Savings Account which protects your savings in a tax-free wrapper, so you will never pay any tax on the interest you earn.

The government decides each tax year how much can be saved in an ISA – this is known as the ISA Allowance or Maximum Annual Subscription Allowance. 

The ISA allowance for the 2024/25 tax year is £20,000. This means you can save £20,000 of new money into your ISA in this tax year.

Our Cash ISA maximum balance is £250,000 so you can transfer other ISA balances into your new Shawbrook ISA up to £250,000.

If these balances are from previous tax years, they do not count towards the £20,000 limit in the current tax year 2024/25.

If you're splitting your ISA allowance over several ISAs, the maximum deposit across all of your accounts is £20,000.
