What is a cash ISA?

If you are looking for a safe place for your savings with some added benefits, then a cash ISA is a good option. 

ISA stands for Individual Savings Account and it was first introduced by the government in 1999 as a way of encouraging people to save. The government said that this type of savings account would avoid any income tax, but there would be a limit on how much you could save in one each year. 

For example, in the 2024/25 tax year you can put up to £20,000 in a cash ISA. You’ll then be able to earn interest on this savings pot without paying any tax. You must also be 18 and over to open an ISA, and under 40 if you're opening a lifetime cash ISA.

You'll never pay tax on the interest you earn with a cash ISA."

Types of cash ISA

Fixed-rate cash ISA

Fixed-rate cash ISA

If you don’t need to access your money for a while, a fixed-rate cash ISA could work for you. You’ll need to lock it away for a specific period, normally between one and five years, but you’ll then get a competitive interest rate.

Junior cash ISA

Lifetime cash ISA

A lifetime cash ISA is worth considering if you are keen to buy a house or save for retirement. You can put up to £4,000 in this ISA between the ages of 18 and 50 and then the government will add 25%.

What is the difference between a cash ISA and a normal savings account?

Generally, a cash ISA is very similar to a standard savings account but there are three things you should consider before signing up. 

  • The money you make in interest in tax-free 

  • You can pay into more than one cash ISA each year and it doesn’t have to be the same account as you opened last year 

  • There is a limit on how much you can pay into the account, for example this tax year it’s £20,000 per person

It's important to remember an ISA works around the tax year, not the calendar year. This means the amount of money you can put into an ISA resets on April 6.

To find the best deals we compare products by taking various factors into consideration, including the interest rate (AER), the balance needed to get the highest interest rate, minimum initial deposit, withdrawal conditions, and the term of the account. These factors change subject to the category of account. 

We use this system for the whole of the market covering nearly all account providers, so you can get an overview of what is available and compare savings accounts in the UK. All the banks featured are FSCS protected, so you can be reassured that your money is safe, provided it’s within the defined limits and regulations.

What is the best ISA rate for 2022?

The best ISA rates are always changing, so we’ve looked at the market and compiled some top picks on our best savings accounts page. 


Are cash ISAs worth it?

Yes, a cash ISA is still worth looking at as it provides a safe and convenient way of saving money tax-free. 


Is my money safe in a cash ISA?

Yes, the Financial Services Compensation Scheme (FSCS) is in place to ensure that your money is protected up to £85,000. For extra peace of mind, it’s best to check with your bank that it is covered by FSCS. 


How many ISAs can I have?

You can pay into multiple ISAs in a single tax year. You can have one easy access cash ISA, one fixed-rate cash ISA, one stocks and shares ISA and one lifetime ISA if you wish - but don't forget your limit across all your ISAs can't exceed £20,000.

Are my finances checked when I open a savings account?

Banks don't take your credit score into account, so this means you should be able to open an ISA if you have bad credit.
