Q: If you exceed your ISA allowance

It is not possible to pay more than £20,000 into your ii ISA as we limit your total contributions to £20,000 per tax year. You could accidentally exceed your allowance by paying more than £20,000 combined into your ii ISA and an ISA with another provider. If this happens, HMRC should be in touch with you after the end of the tax year to advise on next steps.

Q: Adding cash to your ISA

The easiest way to add cash to your ISA is by debit card .

In the 2022-23 tax year, the ISA allowance is £20,000. This is the total amount you can invest in ISAs each year without paying any tax on the gains.

The current tax year runs from 6 April 2022 to 5 April 2023.

You can check your ISA allowance by:

Selecting Cash & transfers > add cash from your account menu.
Choosing your ISA from the 'into your' dropdown menu.
Your remaining allowance will be displayed under add this amount (£s).

How the ISA allowance works

The ISA allowance applies across all your ISAs. You can split your annual £20,000 allowance between different accounts – including a Stocks and Shares ISA, a Cash ISA and a Lifetime ISA (up to £4,000).

You can contribute to more than one type of ISA, but not to more than one of the same type in the same tax year.

You cannot carry over unused ISA allowance from a previous tax year.
