ISA Allowance 2026-27
Every ISA limit in one place — overall, Cash, Stocks & Shares, Lifetime ISA and Junior ISA — plus how many ISAs you can hold, and the cash ISA change announced for April 2027.
ISA allowances — 2026-27 and 2025-26

| Cash ISA | Up to £20,000 (shares overall limit) | Up to £20,000 (shares overall limit) |
| Stocks & Shares ISA | Up to £20,000 (shares overall limit) | Up to £20,000 (shares overall limit) |
| Lifetime ISA (LISA) | £4,000 (counts inside overall) | £4,000 (counts inside overall) |

The April 2027 cash ISA change, explained
From 6 April 2027, the Cash ISA annual limit falls to £12,000 for savers under 65, while savers aged 65 and over keep the full £20,000. The overall £20,000 ISA allowance is unchanged.
In practice: from 6 April 2027, a saver under 65 can still put the full £20,000 into ISAs overall, but only £12,000 of it can sit in cash — the remaining £8,000 has to go into a Stocks & Shares ISA, an Innovative Finance ISA, or a Lifetime ISA. Savers aged 65 and over are unaffected and keep the full £20,000 cash ISA limit.

How many ISAs can I have?
There's no limit on how many ISA accounts you can hold over your lifetime. Since 6 April 2024, you can also pay into more than one ISA of the same type within a single tax year — for example, two Cash ISAs with different providers — as long as your combined subscriptions across every ISA stay within the £20,000 overall allowance. Two exceptions: you can only subscribe to one Lifetime ISA per tax year, and one Junior ISA of each type (cash or stocks & shares) per tax year.
Lifetime ISA rules summary
Up to £4,000 per year (inside the overall £20,000 allowance), with a 25% government bonus added on top — up to £1,000/year. You can open one between age 18 and 39, and keep contributing until age 50. Penalty-free withdrawal is from age 60, or earlier for a first home costing up to £450,000. Any other withdrawal triggers a 25% charge. Model your own numbers in the Lifetime ISA Calculator.
ISA vs pension
An ISA is funded with after-tax money but every withdrawal is 100% tax-free at any age. A pension gets tax relief going in but withdrawals (beyond the 25% tax-free lump sum) are taxed as income, and access is locked until your Normal Minimum Pension Age. Which wins depends mainly on your tax rate now versus in retirement — see the full side-by-side comparison and worked examples in our ISA vs Pension guide.
Tax treatment inside vs outside an ISA
Interest, dividends and capital gains earned inside any ISA are completely tax-free, with no cap on how large the pot grows and nothing to declare. Outside an ISA, savings interest uses your Personal Allowance, the starting rate for savings, and the Personal Savings Allowance before any tax is due — see exactly how much of your interest is tax-free in our Tax on Savings Interest calculator.
Frequently asked questions
What is the ISA allowance for 2026-27?
The overall ISA allowance for 2026-27 is £20,000 — the same as 2025-26. This is the total you can pay into ISAs of all types combined (Cash, Stocks & Shares, Innovative Finance and Lifetime ISA) in one tax year. It resets every 6 April and cannot be carried forward — unused allowance is lost.
How many ISAs can I have?
You can hold as many ISA accounts as you like across your lifetime, and since 6 April 2024 you can pay into more than one ISA of the SAME type in a single tax year (for example, two different Cash ISAs with different providers) — as long as your total subscriptions across all ISAs stay within the £20,000 overall limit. The exceptions: you can still only pay into one Lifetime ISA per tax year, and one Junior ISA of each type per tax year.
What is the Lifetime ISA (LISA) limit?
You can pay up to £4,000 per year into a Lifetime ISA — this counts inside your overall £20,000 ISA allowance, not on top of it. The government adds a 25% bonus on top (up to £1,000/year), but withdrawals before age 60 for anything other than a first home (up to £450,000) trigger a 25% charge that claws back the bonus and some of your own money.
What is the Junior ISA (JISA) limit?
The Junior ISA allowance is £9,000 per child for 2026-27 — separate from an adult's own £20,000 allowance. A parent or guardian can open a JISA for a child under 18 living in the UK who doesn't already have a Child Trust Fund; the child gains control of the account at 16 but can't withdraw until 18.
What is changing with cash ISAs from April 2027?
From 6 April 2027, the Cash ISA annual limit falls to £12,000 for savers under 65, while savers aged 65 and over keep the full £20,000. The overall £20,000 ISA allowance is unchanged. Announced at Autumn Budget 2025.
Who is exempt from the 2027 cash ISA change?
Savers aged 65 and over keep the full £20,000 cash ISA limit from 6 April 2027 — only savers under 65 are restricted to £12,000 in a Cash ISA. The overall £20,000 ISA allowance is unchanged for everyone; under-65s simply need to put the remaining £8,000 into a Stocks & Shares ISA, Innovative Finance ISA, or Lifetime ISA instead of cash.
Is interest, dividends and growth inside an ISA really tax-free?
Yes. Interest, dividends and capital gains earned inside any type of ISA are completely free of Income Tax and Capital Gains Tax, with no limit on how large the pot grows, and none of it needs to be declared on a tax return. Outside an ISA, savings interest and dividends use up separate allowances — see our tax on savings interest page for how those work.
