What is the ISA allowance for 2026?
The ISA allowance is £20,000 for 2026/27 — the total you can pay into all your ISAs combined in one tax year. All interest, dividends and capital gains inside an ISA are completely tax-free, and the allowance resets every 6 April.
Full answer
For the 2026/27 tax year you can pay up to £20,000 into Individual Savings Accounts. This is a combined limit across Cash ISAs, Stocks and Shares ISAs, Innovative Finance ISAs and Lifetime ISAs — you can split it however you like, though the Lifetime ISA has its own £4,000 sub-limit. Everything inside an ISA grows free of Income Tax, Capital Gains Tax and Dividend Tax, and withdrawals are tax-free too. The allowance is "use it or lose it": it resets on 6 April each year and cannot be carried forward. Worked example: you could put £16,000 in a Cash ISA and £4,000 in a Lifetime ISA in the same year, using your full £20,000 — and the Lifetime ISA adds a 25% government bonus on its £4,000, worth £1,000. With a flexible ISA you can withdraw and replace money within the same tax year without it counting again towards the limit. The Junior ISA allowance is separate at £9,000 for under-18s. ISAs are particularly valuable for higher and additional-rate taxpayers, who get little or no Personal Savings Allowance. The £20,000 limit applies UK-wide, including Scotland.
