What is the ISA allowance for 2026/27?
The ISA allowance for 2026/27 is £20,000. This can be split across a Cash ISA, Stocks and Shares ISA, Innovative Finance ISA, or Lifetime ISA (limited to £4,000). The Junior ISA limit is £9,000 for 2026/27.
Full answer
The ISA (Individual Savings Account) allowance for 2026/27 is £20,000, unchanged from previous years. This annual allowance can be split in any proportion across the following ISA types: Cash ISA, Stocks and Shares ISA, Innovative Finance ISA (IFISA), and Lifetime ISA (LISA — limited to £4,000 of the £20,000). The Junior ISA allowance is a separate £9,000 per child per tax year. All income and gains within an ISA are free of Income Tax and Capital Gains Tax. Once you have used your annual allowance, any unused amount cannot be carried forward to the next tax year. Flexible ISAs allow withdrawals and re-contributions within the same tax year without losing the allowance.
