The annual ISA subscription allowance stays at £20,000 for 2026/27, unchanged since 2017/18. The Junior ISA and Child Trust Fund limit remains £9,000, and the Lifetime ISA cap is still £4,000 (counting towards the £20,000 total).
The freeze means that, in real terms, the ISA allowance has lost around a quarter of its purchasing power since it was last raised. For higher earners with significant taxable savings, the practical effect is that more interest and gains spill into Personal Savings Allowance, dividend and Capital Gains Tax territory each year.
The flexible ISA rules remain in force, allowing savers who withdraw and replace money in the same tax year not to lose any of their allowance. The British ISA proposal floated in 2024 has not been revived.
If you have not used this year's allowance, you have until 5 April 2027 — but only one Cash ISA, one Stocks & Shares ISA, one Innovative Finance ISA and one Lifetime ISA can be paid into within the same tax year under the post-2024 rules.
