How many ISAs can I have? (2026/27 rules)

You can hold as many ISAs as you like, and since April 2024 you can even pay into several of the same type in a single tax year. What you cannot do is exceed one £20,000 allowance across all of them.

The rule that changed in April 2024

Until April 2024, you could only pay new money into one ISA of each type per tax year. That rule is gone. Since 6 April 2024 you can open and pay into multiple cash ISAs, or multiple stocks and shares ISAs, in the same year, spreading your money across providers to chase better rates or funds.

The main exceptions are the Lifetime ISA and the Junior ISA: you can still only pay into one of each in a given tax year. Everything you pay in, across every ISA, still has to fit inside a single annual allowance.

The four types of adult ISA

There are four kinds of ISA an adult can use, and your £20,000 can be split across them however you like:

• Cash ISA: tax-free savings that earn interest.
• Stocks and shares ISA: tax-free investments in funds, shares and bonds.
• Lifetime ISA: for a first home or retirement, with a 25% government bonus, capped at £4,000 a year.
• Innovative finance ISA: peer-to-peer lending, higher risk and less common.

Children under 18 have a separate Junior ISA with its own £9,000 allowance, which does not touch the adult limit.

One £20,000 allowance across the lot

The number that actually constrains you is the total. In 2026/27 you can pay in £20,000 across all your ISAs combined, not £20,000 into each. Put £12,000 in a cash ISA and £8,000 in a stocks and shares ISA and you are done for the year. Spread across four cash ISAs at three providers, the £20,000 ceiling still applies to the sum.

The Lifetime ISA carries an extra limit inside that total: a maximum of £4,000 a year, which earns up to £1,000 of bonus. So the most you could route through a LISA is £4,000, leaving £16,000 for your other ISAs. Deciding how to split the allowance is where the cash ISA vs stocks and shares choice comes in.

Transfers do not touch your allowance

Moving existing ISA money from one provider to another is a transfer, not a new contribution, so it does not use any of your £20,000. You could transfer £50,000 built up over past years into a better-paying account and still have the full £20,000 to add this year.

Two things matter here. Always use the provider's transfer process rather than withdrawing and re-depositing, because taking the money out yourself strips its ISA status and it would count as a fresh contribution going back in. And since April 2024 you can make partial transfers of current-year money, so you can move part of this year's ISA and leave the rest where it is.

Common questions

How many ISAs can I have in 2026/27?

As many as you like in total, and since April 2024 you can pay into more than one of the same type in a single tax year. The only limits are one Lifetime ISA and one Junior ISA per year, and a combined £20,000 allowance across all of them.

Can I pay into two cash ISAs in the same year?

Yes. Since 6 April 2024 you can open and pay into multiple cash ISAs, or multiple stocks and shares ISAs, in the same tax year. Your total contributions across all ISAs still cannot exceed the £20,000 annual allowance.

Does transferring an ISA use my annual allowance?

No. Transferring existing ISA money between providers does not count as a new contribution, so it leaves your full £20,000 allowance intact. Always use the provider transfer process; withdrawing the money yourself would lose its ISA status.

How much can I put in a Lifetime ISA each year?

Up to £4,000, which earns a 25% bonus of up to £1,000. That £4,000 counts towards your overall £20,000 ISA allowance, and you can only pay into one Lifetime ISA in a given tax year.
