What is the ISA allowance for 2026/27?
The ISA allowance for 2026/27 is £20,000 per adult. This can be split across a Cash ISA, Stocks and Shares ISA, Innovative Finance ISA and/or Lifetime ISA (max £4,000 to LISA). Junior ISA allowance is £9,000 (separate). The allowance resets on 6 April 2027.
Full answer
For the 2026/27 tax year (6 April 2026 to 5 April 2027), UK adults can save or invest up to £20,000 in ISAs. The £20,000 limit has been unchanged since 2017/18. Types of ISA available: Cash ISA (interest tax-free), Stocks and Shares ISA (investment growth and dividends tax-free), Innovative Finance ISA (peer-to-peer lending returns tax-free), and Lifetime ISA (bonus of 25% on contributions up to £4,000, for first-time buyers or retirement savings). The £20,000 can be split across multiple ISA types in the same tax year — for example, £10,000 in a Cash ISA and £10,000 in a Stocks and Shares ISA. However, you can only subscribe to one ISA of each type in a single tax year. The LISA counts toward the £20,000 annual limit (so a £4,000 LISA contribution leaves £16,000 for other ISAs). Flexible ISAs allow withdrawals and re-deposits in the same tax year without losing allowance — but not all ISA providers offer flexible accounts. Junior ISAs: the separate £9,000 JISA limit allows parents (or the child after age 16) to save for the child's future. ISAs cannot be held jointly — each person has their own allowance. Transfers between ISA providers (including switching type, e.g., Cash to Stocks and Shares) do not use up new allowance. From April 2024, rules were relaxed to allow multiple ISAs of the same type and partial transfers.
