How Many Cash ISAs Can I Have

How Many Cash ISAs Can I Have

If you are looking to make the most of your tax-free savings, you may be wondering how many Cash ISAs you can have. The rules changed in April 2024, giving UK savers more flexibility than before.

Because of this, it is now possible to hold and pay into more than one Cash ISA in the same tax year, as long as your total contributions stay within the overall annual allowance.

This guide explains how many Cash ISAs you can have, how many you can open in a year, what to consider before opening more than one, and upcoming changes that could affect how you save.

Can You Have More Than One Cash ISA?

Yes, in the 2026/27 tax year you can have more than one Cash ISA. Before April 2024, savers were only able to pay into one Cash ISA per tax year.

Under the current rules, it is possible to hold and contribute to multiple Cash ISAs with different providers in the same tax year. You can hold as many as you like, provided you do not exceed the annual ISA allowance - which is currently set at £20,000.

This change gives savers the option to spread their money across different types of Cash ISAs.

For example, you might hold a Fixed Rate Cash ISA for part of your savings and an Instant Access Cash ISA for funds you may need sooner.

A Few General Rules to Remember

There is no set limit on how many Cash ISA accounts you can have in total. You can hold Cash ISAs from previous tax years alongside new ones, and open additional accounts as your savings goals change.

That said, there are a few points to keep in mind when considering:

• Your total contributions across all ISAs in a tax year cannot exceed £20,000 (the 2026/27 allowance).
• Some providers may limit how many of their Cash ISAs you can hold with them, even where the wider HMRC rules would permit it. It is worth checking with the provider before applying.
• Lifetime ISAs are treated differently, with only one account able to receive contributions per tax year.

So, while there is no official cap, it is sensible to keep the picture manageable and avoid losing track of contributions.

Why Savers Might Open More Than One Cash ISA

There are a few reasons someone might choose to open more than one Cash ISA in a single tax year:

• To split savings between a fixed rate product and a variable rate product.
• To access different rates available across providers.
• To keep separate savings goals in separate accounts, such as a house deposit and an emergency fund.
• To transfer existing ISA balances while continuing to contribute to a different account.

What Is the Current Cash ISA Allowance?

The annual ISA allowance for the 2026/27 tax year is £20,000. This figure applies to all ISA contributions combined, including Cash ISAs, Stocks and Shares ISAs, Innovative Finance ISAs, and Lifetime ISAs (which have their own £4,000 sub-limit).

It is worth noting that from April 2027, the government has proposed plans to cap contributions to Cash ISAs at £12,000 a year for savers under 65, although the overall £20,000 ISA allowance will continue to apply across all types. Savers aged 65 and over will keep the full £20,000 Cash ISA allowance.

It is important to keep up to date with the allowance rules before structuring your savings. You can visit the governments website for most up to date ISA rules: Individual Savings Accounts (ISAs): Overview - GOV.UK

What Happens If You Exceed the Annual Allowance?

If you accidentally pay more than £20,000 into your ISAs in a tax year, you will need to contact your ISA provider or HMRC, so that they can carry out any corrective actions.

Keeping a record of all your ISA contributions makes it easier to stay within the allowance, particularly when paying into more than one account.

Things to Consider Before Opening Multiple Cash ISAs

If you decide to open more than one Cash ISA, there are a few practical points to think about.

Keep Track of Contributions

Keeping track of contributions across accounts becomes more important when using several providers, as exceeding the allowance can cause complications. It is sensible to record each deposit and the account it was paid into.

Different Products Suit Different Goals

A Fixed Rate Cash ISA typically pays a set rate of interest for a defined term, while an Instant Access or Limited Access Cash ISA offers more flexibility with withdrawals. Holding more than one type allows savers to match different portions of their money to different needs.

Summary

So, how many Cash ISAs can you have? As many as you need, provided your contributions stay within the £20,000 annual allowance.

The rule change in April 2024 means savers can pay into multiple Cash ISAs in the same tax year, whether that means spreading money across providers or combining different account types. With a further change coming in April 2027 for under-65s, it is worth keeping up to date with the allowance rules before planning your savings.
