Any returns you get from a cash ISA is tax free, meaning you get to keep all of the interest you earn from your money.

Which cash ISA should you choose?

Look for the cash ISA that pays the highest interest rate but also gives you the access you need to your money.

You can choose from one of the following cash ISAs:

  • Instant access: you can withdraw your money anytime

  • Easy access: you can withdraw anytime, but it can take a few days to get your money

  • Notice: you have to give notice to withdraw or be penalised interest, e.g. 60 days

  • Regular saver: you have to save money every month to qualify for the interest rate

  • Fixed term (1 to 5 years): your money is tied up for the whole term* with a fixed rate

* Some fixed term ISAs let you withdraw before the end of the term but charge you an interest penalty.

Compare as many cash ISA rates in our table as possible to find the best account.

Are there any alternatives?

If you are a basic rate taxpayer, you also have a personal savings allowance which lets you earn up to 1,000 in interest without paying tax in the 2018/19 tax year. This amount drops to 500 for higher rate taxpayers.

Your personal savings allowance is in addition to any interest you make from ISAs.

How much can you pay into a cash ISA?

Your ISA allowance is currently 20,000 and can be spread across a cash ISA, stocks and shares ISA and innovative finance ISA in a single tax year (6th April untill 5th April) .

Some cash ISAs only require you to pay in 1 when you open them, but some require a minimum deposit up to 15,000.

If you already have an ISA, you can sometimes transfer it to a new ISA and add further funds as long as you have not already used up your allowance for the current tax year. Our table shows you which ISAs accept transfers.
