Track how much of your £20,000 allowance you have used across cash, stocks & shares and Lifetime ISAs — and understand why this tax year is different from the ones after it.
Open the ISA tracker →This is the last year of the £20,000 cash ISA for under-65s. From 6 April 2027 the cash ISA limit falls to £12,000 a year for anyone under 65. The overall £20,000 allowance stays — the other £8,000 can still go into a stocks & shares ISA — and savers aged 65+ keep the full £20,000 cash limit. If you hold savings in cash and want them sheltered, the 2026/27 allowance matters more than usual, because next year you will not be able to shelter as much of it in cash.
| Account | 2026/27 limit | Notes |
|---|---|---|
| Overall ISA allowance | £20,000 | Across all your ISAs combined |
| Cash ISA | £20,000 | Falls to £12,000 for under-65s from April 2027 |
| Stocks & shares ISA | £20,000 | Within the overall allowance |
| Lifetime ISA | £4,000 | Counts toward the £20,000; 25% government bonus |
| Junior ISA | £9,000 | Separate — does not use your allowance |
It is use-it-or-lose-it. Anything uncontributed by 5 April 2027 is gone. This is why ISA activity spikes every March — and why leaving it to the last week risks missing transfer and processing deadlines.
Put £4,000 into a LISA and you have £16,000 of overall allowance left. The 25% bonus — up to £1,000 a year — makes it the highest guaranteed return available for a first home deposit, but the 25% withdrawal charge for taking money out for anything else (before 60) means you get back less than you put in. It is a commitment, not a savings account.
Unless your ISA is a flexible ISA, money you withdraw does not restore your allowance. Deposit £15,000, withdraw £10,000, and you can still only add £5,000 more this year. Flexible ISAs let you replace withdrawals within the same tax year — but not all providers offer them, and it is worth checking before you move money.
| Destination | Amount | What you get |
|---|---|---|
| Lifetime ISA | £4,000 | +£1,000 government bonus |
| Cash ISA | £8,000 | Tax-free interest, instant access |
| Stocks & shares ISA | £8,000 | Tax-free growth and dividends |
| Total contributed | £20,000 | +£1,000 bonus on top |
