What is a cash Isa?
A cash Isa (individual savings account) is a tax-free “wrapper” for your money. That means you are sheltered from paying tax on any interest earned in one. Read our Isa guide for more information.
If you don’t use an Isa for your savings then you need to be careful not to breach the personal savings allowance.
There are broadly two types of cash Isa: easy-access and fixed.
- Easy access: you can withdraw money whenever you like and the rate is likely to change
- Fixed: pays a set level of interest over a certain period of time and your money is usually locked in for the duration of the deal
The government limits how much you can save into your Isa each tax year while still enjoying the tax-free benefits.

During the current financial year, you can save up to £20,000 a year in Isa products. You can spread the allowance across difference types of Isa such as cash or stocks and shares.
If you are worried about exceeding your personal savings allowance or don’t have one, a cash Isa is a useful product to protect your savings income from tax. We explain how savings interest is taxed in our guide on the personal savings allowance.

How many cash Isas can I have?
Previously, you could only invest in one Isa type each tax year. For example, if you opened an easy access cash Isa and deposited £10,000, you weren’t allowed to open a fixed rate cash Isa and use up your remaining allowance.
Instead, the remaining £10,000 would need to be invested in an alternative account such as a stocks and shares Isa.
It was only when the tax year ended you could have opened this fixed-rate Isa with your refreshed allowance. Alternatively, you could have closed your easy access cash Isa and transferred your funds to your chosen fixed-rate account.
As of the new tax year, this rule has been abolished and you’re free to invest in as many Isas as you see fit.
You can also still transfer Isa allowances between providers and products.

Best fixed-rate cash Isas
Fixed-rate cash Isas usually pay a higher interest rate than the easy-access accounts because your money is tied up for a set length of time.
Watch out, as you may have to pay a penalty to withdraw money early from a fixed account. Always read the terms and conditions of products carefully.
Also bear in mind that if you aren’t looking for an Isa, a standard savings account might pay higher rates. We outline the top-paying savings accounts.

Everything you need to know about compound interest
Are cash Isas worth it?
When the government introduced the personal savings allowance in 2016, many people no longer had to pay tax on their interest when using standard savings accounts. So for many people there wasn’t an incentive to open a cash Isa.
However, with the Bank of England raising the base rate of interest, savers are seeing a greater return on their money, which could push them over their personal savings allowance.
Not everyone gets a personal savings allowance either. Read more: What is the personal savings allowance?
We think an Isa can also be a very good idea if you:
- Have a fairly large chunk of money you want to keep in cash
- Are likely to breach the personal savings allowance (or don’t qualify for one)
- Act quickly to get the best deals, as they can go fast
We go into more detail about how cash Isas work.
Once you have a pot of easy-access savings for emergencies, you might want to consider putting your money in a stocks and shares Isa.
In the table below you can also see how the average savings rates on standard accounts compare with Isas and how they have changed.
| Sept 2021 | Dec 2021 | Aug 2022 | Sept 2022 | Mar 2023 | May 2023 | Jul 2023 | Aug 2023 | Jan 2024 | Feb 2024 | Mar 2024 | Apr 2024 | |

Can you lose money in a cash Isa?
If the company you save or invest with goes bust, up to £85,000 of your cash is protected by the Financial Services Compensation Scheme (FSCS).
This only applies as long as your provider is authorised by the Financial Conduct Authority or the Prudential Regulation Authority.
Also bear in mind that inflation will eat away at your savings pot. While the value of your capital won’t fall (unless you spend your savings), the real spending power of your money is likely to decrease over time.
The best way to stop inflation eroding the spending power of your cash is to invest your money in a stocks and shares Isa instead.
This increases the chances of you making a return that exceeds inflation, although remember that investing is never risk free and investment returns are not guaranteed.
Stocks and shares Isas should only really be considered for long-term savings. To find out more, check out our beginners’ guide to investing.
