OpenHow this is calculated
- The total ISA allowance for 2026/27 is £20,000. You can split this in any proportion across a Cash ISA, a Stocks & Shares ISA, and an Innovative Finance ISA, as long as the total across all of them does not exceed £20,000.
- A Lifetime ISA (LISA) has its own sub-limit of £4,000 per year. Any amount you pay into a LISA counts toward the overall £20,000 limit. The government then adds a 25% bonus on top of your contribution, up to £1,000 per year.
- The LISA bonus is paid by HMRC into your LISA account, typically within 6 to 8 weeks of your contribution. It grows free of tax alongside your own money.
- From 6 April 2024 you can pay into more than one ISA of the same type in a single tax year. The total across all your ISAs still cannot exceed the annual allowance.
- If you take money out of a LISA for any reason other than buying your first home (property up to £450,000) or reaching age 60, a 25% government withdrawal charge applies to the amount you take out, including the bonus. This means you can end up with less than you put in.
- Junior ISAs are completely separate. Children under 18 have their own annual allowance of £9,000 for 2026/27. Junior ISA contributions do not count toward or reduce the adult allowance shown here.
Frequently asked questions
What is the ISA allowance for 2026/27?
The annual ISA allowance is £20,000 for 2026/27. This is the maximum you can pay into ISAs in a single tax year, across all ISA types combined. The allowance resets on 6 April each year and cannot be carried forward if unused.
Can I pay into more than one ISA in the same tax year?
Yes, from 6 April 2024. You can now open and contribute to multiple ISAs of the same type in one tax year. Previously you were limited to one of each type per year. The total across all ISAs still cannot exceed the annual allowance.
Does the Lifetime ISA count toward my annual allowance?
Yes. If you contribute £4,000 to a LISA, you have £16,000 left for other ISAs. The 25% government bonus goes on top of your contribution and does not use up any of your allowance.
What happens if I withdraw from a Lifetime ISA?
A 25% withdrawal charge applies to any amount taken out unless you are buying your first home (property up to £450,000) or you are aged 60 or over, or you are terminally ill. The charge is calculated on the withdrawal including the bonus, so on a £1,000 withdrawal you would pay back £250 and keep only £750.
What is an Innovative Finance ISA?
An Innovative Finance ISA (IFISA) holds peer-to-peer loans. You lend money through a platform and receive interest free of income tax, within your annual ISA allowance. IFISAs carry more risk than Cash ISAs: your money is not protected by the Financial Services Compensation Scheme (FSCS) and you could lose some or all of it if borrowers default.
Is there a separate allowance for a Junior ISA?
Yes. A Junior ISA (JISA) has its own annual allowance of £9,000 for 2026/27, completely separate from the adult allowance. Parents or guardians can pay in on behalf of a child under 18. The child cannot access the money until they turn 18.
ISAs are a long game, and the long game is mostly behavioural. Morgan Housel's modern classic is the most-recommended UK personal-finance book for a reason.
