What is the ISA Allowance?

Tax year runs from 6 April to the following 5 April. Each tax year’s ISA subscription limit is specific to that year and can be checked on the HMRC website. 

For the 2023/24 tax year the annual ISA allowance is £20,000 per person. Any of the ISA allowance that goes unused in the current tax year cannot be rolled over to the subsequent tax year. You can divide this cash allowance across multiple ISAs, provided that not more than 1 of each type of ISA is subscribed to in any given tax year.

Please Note

  • If you are already subscribed to another stocks and shares ISA in the current tax year, you are not permitted to subscribe to our stocks and shares ISA for the remainder of the tax year.
  • For each tax year, you can check (via the funding page in Client Portal) how much you have subscribed to your IBUKL Stocks and Shares ISA and the maximum amount that you can contribute to your IBUKL Stocks and Shares ISA in that tax year, assuming you have not contributed to another ISA away from Interactive Brokers.
