Can I Pay Into Two ISAs in the Same Tax Year? (UK 2026/27)

Yes. Since 6 April 2024, you can pay into multiple ISAs of the same type in the same tax year, including more than one cash ISA, more than one stocks & shares ISA, or any combination. The only constraints are: total contributions across all your adult ISAs can’t exceed £20,000 for the year, the Lifetime ISA is capped at £4,000 inside that £20,000, and you still can’t pay into more than one Lifetime ISA in a single year.

This is the new ISA framework that came in for the 2024/25 tax year, fully bedded in for 2026/27.

What changed in April 2024?

Until 5 April 2024, the rule was: you could only pay into one ISA of each type per tax year. So you could open one cash ISA and one stocks & shares ISA, but not two cash ISAs. New providers, better rates, or simply a desire to spread risk were all blocked by this rule.

The 2024 Spring Budget announced reform. From 6 April 2024:

• You can pay into multiple ISAs of the same type within a single tax year.
• You can split your £20,000 allowance across as many ISAs and providers as you like.
• Partial transfers of current-year subscriptions between providers are now allowed.
• The £20,000 overall annual limit remains.
• The £4,000 Lifetime ISA sub-cap remains.
• You still can’t pay into more than one Lifetime ISA in a single tax year (the LISA rule is unchanged).

The change is documented in HMRC’s ISA reform announcement.

What this means in practice

A few examples of what’s now allowed that wasn’t before:

• Open a new cash ISA mid-year for a better rate, while keeping the old one with funds in it. Both can receive new contributions.
• Use two stocks & shares ISA platforms — one for low-cost index funds, one for active investments — funding both in the same year.
• Switch ISA providers without losing the current-year contribution. Previously, transferring a current-year ISA had to involve all of the current year’s subscriptions. Now, partial transfers are permitted.
• Spread cash ISAs across providers for FSCS protection (£85,000 per banking group).

The £20,000 limit is still total

The overall annual allowance is unchanged. Adding up all your contributions across all ISAs:

• Cash ISAs (any number)
• Stocks & shares ISAs (any number)
• Innovative finance ISAs (any number)
• Lifetime ISA (max £4,000 within the £20,000)

The sum can’t exceed £20,000 for the 2026/27 tax year.

A worked example:

• £5,000 into Cash ISA A.
• £5,000 into Cash ISA B with a different provider.
• £8,000 into a stocks & shares ISA.
• £2,000 into a LISA.

Total: £20,000. All within the rules. The LISA receives a 25% bonus (£500), the stocks & shares ISA grows tax-free, both cash ISAs earn tax-free interest. None of this would have been allowed pre-April 2024.

The Lifetime ISA exception

The LISA still has its own rule: only one LISA per tax year. You can’t open two LISAs in the same year and split the £4,000 between them. This is the one type that retains the “single ISA per year” restriction.

If you have a LISA with provider A and want to switch to provider B mid-year:

• You can’t pay into both in the same year.
• You can transfer your LISA from A to B (which doesn’t count as opening a new one or using current-year subscription).
• After the transfer completes, you can continue contributing to B.

The 12-month minimum holding period (before first qualifying withdrawal) survives the transfer — it’s tracked from the original LISA opening, not the transfer.

Can I open multiple LISAs in different tax years?

Yes. You can hold LISAs from previous tax years with one provider while paying into a new LISA with a different provider this tax year — provided you only fund one LISA per tax year.

In practice, most people who’ve had a LISA for several years stay with one provider for simplicity. Switching is allowed via transfer.

What about Junior ISAs?

The reform allowed multiple adult ISAs of the same type. Junior ISAs are separate and have their own rules:

• A child can hold at most two Junior ISAs at any time: one Junior Cash ISA and one Junior Stocks & Shares ISA.
• A child can’t hold multiple Junior Cash ISAs simultaneously, even after the 2024 reform.
• The combined Junior ISA allowance is £9,000 per tax year, separate from the adult £20,000.

Why would I want multiple ISAs of the same type?

A few legitimate reasons:

1. Better rates mid-year. If you opened a cash ISA in April at 4.5% and a leading-edge rate of 5% appears in November, you can pay further contributions into the new ISA without leaving the first.
2. FSCS protection split. £85,000 protection per banking group. Holding more than £85,000 in cash ISAs at a single group is unprotected; splitting across providers is safer.
3. Platform flexibility for investing. Different stocks & shares platforms offer different investment ranges, tools, and fee structures. Using two can give you access to features one alone doesn’t offer.
4. Risk separation. Mainstream stocks & shares ISA on one platform; experimental higher-risk holdings on another — keeping the exposures visually separate.
5. Specific product needs. A regular saver cash ISA at 6%+ for £200/month, combined with an easy-access cash ISA for the rest.

What hasn’t changed

Some things are still the same:

• The £20,000 overall annual limit.
• The LISA “one per year” rule.
• The £4,000 LISA cap within the £20,000.
• The need to be UK resident to subscribe.
• The ISA wrapper’s tax-free status on interest, dividends and capital gains.
• The ISA transfer process for moving funds between providers.

Worked example: split contributions across three providers

Mia, a 28-year-old saving for a house deposit, has £20,000 to put into ISAs in 2026/27. Her plan:

• £4,000 into Lifetime ISA at Provider A (locked in for first-home / age 60). Gets £1,000 bonus.
• £5,000 into Cash ISA at Provider B, paying ~4.5% easy access.
• £3,000 into Cash ISA at Provider C, a 1-year fixed rate at 4.8%.
• £8,000 into Stocks & Shares ISA at Provider D, invested in a global index fund.

Total: £20,000 split across 4 ISAs at 4 providers, all within the rules.

Pre-April 2024 this wasn’t allowed — only one cash ISA per year was permitted. Now it’s standard practice for people who want to optimise across providers.
