TL;DR: Yes. From 6 April 2024 a UK saver can pay into multiple Individual Savings Accounts of the same type in the same tax year (except for the Lifetime ISA and the Junior ISA, where the one-per-tax-year rule remains). The total subscription across all ISAs in the tax year is still capped at 20,000 pounds (2026-27 figure), with the Lifetime ISA sub-capped at 4,000 pounds and the Junior ISA at 9,000 pounds per child. A saver can therefore split the 20,000-pound allowance across, say, two cash ISAs at two different providers, a stocks-and-shares ISA, and an innovative finance ISA, in the same year. Partial transfers of current-year subscriptions between ISA managers are also permitted from 2024-25 onwards. The reforms were introduced by the Finance (No.2) Act 2023 and implemented through amendments to the Individual Savings Account Regulations 1998.

The rules on how many ISAs a UK saver can hold and pay into changed materially from 6 April 2024. Before that date the long-standing rule was that a saver could subscribe to only one of each ISA type per tax year. The 2024 reforms removed that restriction for most ISA types, allowing multiple ISAs of the same type to be funded in a single tax year - subject to the overall 20,000-pound annual subscription limit.
This guide explains exactly how the new rules work, which ISA types still have the one-per-year restriction, how the overall subscription limit is shared, when transfers between providers count against the limit and when they do not, and the practical reasons a saver might want multiple ISAs of the same type.
What changed in April 2024
The Finance (No.2) Act 2023 announced a package of ISA reforms with effect from 6 April 2024, implemented through amendments to the Individual Savings Account Regulations 1998. The headline change is that a saver can now subscribe to multiple ISAs of the same type in the same tax year, provided the overall subscription limit is not exceeded.
Before April 2024 a saver who had subscribed to a cash ISA with one provider had to wait until the next tax year before opening a cash ISA with a different provider. This made it cumbersome to take advantage of a better rate or product offered later in the tax year, because the new provider had to be a "transfer in" of the existing subscription rather than a new account.
The new flexibility means a saver who opens a cash ISA in April 2025 with provider A and contributes 5,000 pounds, then sees a better rate from provider B in October 2025, can open a new cash ISA with provider B and contribute up to a further 15,000 pounds in the same tax year - no transfer required, no waiting for the next tax year.
Which ISA types are covered by the new rule
The new "multiple ISAs of the same type" rule applies to cash ISAs, stocks-and-shares ISAs, and innovative finance ISAs. A saver can hold multiple of any combination of these in the same tax year.
The Lifetime ISA (LISA) is excluded: only one LISA per tax year, with the 4,000-pound sub-cap as before. The reasoning is that LISA carries a government bonus and the single-LISA-per-year rule prevents some types of bonus-stacking arrangement.
The Junior ISA (JISA) is also excluded: only one cash JISA and one stocks-and-shares JISA per child at any time, with a single subscription stream into each. The JISA is held in the child's name with the parent as registered contact, and the practical reason for the restriction is administrative simplicity rather than tax-avoidance prevention.
The Help to Buy ISA is closed to new accounts, but existing holders can continue subscribing under the original rules until December 2030.
The overall subscription limit
The total ISA subscription allowance is 20,000 pounds per tax year (2026-27 figure, frozen since 2017-18). The allowance is the maximum total new money that can be paid in across all the saver's ISAs in the year - regardless of how many separate accounts they have.
A saver with three cash ISAs, two stocks-and-shares ISAs, and an innovative finance ISA in the same tax year is still limited to 20,000 pounds in total subscriptions across all of them. The flexibility is in how the allowance is split, not in the size of the allowance.
The Lifetime ISA sub-cap of 4,000 pounds is inside the 20,000-pound overall limit. A saver who puts 4,000 pounds in a LISA in the year has 16,000 pounds of allowance left for other ISA types. The 25 percent government bonus on LISA contributions (up to 1,000 pounds a year) is on top of the saver's own subscription, not counted against the 20,000-pound limit.
The Junior ISA has its own separate 9,000-pound annual allowance per child, distinct from the adult 20,000-pound limit. A parent funding a Junior ISA does not use up their own annual ISA allowance.
How transfers work alongside the new rules
Transfers between ISA providers do not count as subscriptions and do not use up the annual allowance. A saver who transfers an old cash ISA holding from provider A to provider B keeps the original year-by-year subscription history intact.
Before April 2024, transfers of current-year subscriptions had to be the whole of the current-year subscription (partial current-year transfers were not allowed). From 2024-25 partial transfers of current-year subscriptions are also permitted, giving savers more flexibility to move money during the tax year.
The ISA transfer process must be used (request a transfer from the receiving provider; the receiving provider organises the transfer in with the sending provider). A saver who withdraws ISA money and pays it back in elsewhere creates a new subscription against the annual allowance - and loses the ISA wrapper on the original money.
Some cash ISAs are "flexible": the saver can withdraw money and pay it back within the same tax year without using up new allowance. Flexibility is a feature offered by some ISA providers and disclosed in the product literature; not all ISAs are flexible.
Practical reasons to hold multiple ISAs of the same type
The most common reason is rate-chasing: the saver opens a cash ISA at the start of the tax year at the best rate then available, but a better rate appears later in the year. Under the new rules, the saver can simply open a new cash ISA with the new provider and contribute the remainder of the annual allowance there, leaving the earlier subscription where it is.
Another reason is risk diversification across stocks-and-shares ISA providers. A saver who wants to spread investment platform risk (the FSCS investment protection covers up to 85,000 pounds per saver per investment firm) can hold stocks-and-shares ISAs with two or three different providers, each well within the FSCS cap.
A saver may also want different products with different providers: a cash ISA at one bank for emergency savings; a stocks-and-shares ISA at a low-cost platform for long-term equity exposure; an innovative finance ISA at a peer-to-peer platform for higher-yielding (and higher-risk) lending. Combining these in a single year is now straightforward.
For higher-rate or additional-rate taxpayers who exceed their Personal Savings Allowance, the cash ISA wrapper is materially better than an ordinary savings account from the first pound of interest. The new flexibility makes it easier to deploy the 20,000-pound allowance optimally rather than being locked into a single provider's product range.
How HMRC tracks multiple ISAs
ISA providers report annual subscription totals to HMRC for each saver, using the saver's National Insurance number as the identifier. HMRC aggregates the subscriptions across all reported ISAs and checks that the total does not exceed 20,000 pounds.
Where a saver inadvertently exceeds the limit (typically by misunderstanding which year a subscription falls into), HMRC writes to the saver explaining that the excess is "not a valid subscription". The excess must be removed, and tax may be due on the interest or growth attributable to the excess from the date of the over-subscription.
The new multiple-ISAs rule makes the aggregation reporting more important for HMRC, but the principle is unchanged: subscriptions across all ISAs combined must not exceed 20,000 pounds. ISA providers are required to verify the saver's NI number at account opening to ensure correct reporting.
How we verified this
The current ISA rules including the multiple ISAs of the same type provision reflect the Finance (No.2) Act 2023 and the amendments to the Individual Savings Account Regulations 1998 effective from 6 April 2024. The annual subscription allowance of 20,000 pounds, the Lifetime ISA sub-cap of 4,000 pounds, and the Junior ISA allowance of 9,000 pounds reflect current HMRC published rates. The partial current-year transfer rule reflects the 2024 amendments to the ISA Regulations. The Help to Buy ISA wind-down reflects the original 2017 closure to new accounts and the 2030 final claim deadline. FSCS investment compensation reflects the FCA Handbook (COMP rules). No specific ISA provider names, product rates, or HMRC reference numbers have been invented.

Frequently asked questions
Can I have more than one ISA account?
Yes. From 6 April 2024 a UK saver can hold and pay into multiple ISAs of the same type in the same tax year, subject to the overall 20,000-pound subscription limit. The Lifetime ISA and the Junior ISA are the only types where the one-per-tax-year rule still applies.
Can I open two cash ISAs in one tax year?
Yes, from 2024-25 onwards. A saver can open a cash ISA with provider A, contribute part of the year's allowance, then open a cash ISA with provider B and contribute the rest, all in the same tax year. The total across both must not exceed 20,000 pounds. Before April 2024 this was not permitted.
Does opening multiple ISAs increase my tax-free allowance?
No. The annual ISA subscription allowance is 20,000 pounds per saver per tax year (2026-27), regardless of how many separate ISAs the saver opens. The flexibility of the new rules is in how the allowance is split, not in the size of the allowance.
Can I transfer ISA money between providers without losing the allowance?
Yes. The ISA transfer process moves money from one provider to another without it counting as a new subscription. The saver should use the receiving provider's transfer-in process; withdrawing the money and paying it back elsewhere creates a new subscription and uses up the annual allowance.
Can I have a Lifetime ISA and a cash ISA in the same year?
Yes. The new "multiple ISAs of the same type" rule does not restrict combining ISAs of different types. A saver can hold a Lifetime ISA (up to 4,000 pounds a year), one or more cash ISAs, a stocks-and-shares ISA, and an innovative finance ISA in the same tax year. Total subscriptions across all of them must not exceed 20,000 pounds, with the 4,000-pound LISA sub-cap counting inside the overall limit.
