ISAs

Choosing the best ISA

Individual savings accounts, or ISAs, let you save money and earn interest on up to £20,000 without paying any tax on what you earn. You’ll be given an allowance for every tax year, and for 2020/21 the allowance is £20,000, which you can put into a number of different types of ISA.

You must be at least 16-years-old to be eligible for an ISA.


Every year you’ll be able to open a new ISA and pay in up to £20,000 over the year. You can have several ISAs open at the same time, but keep in mind that after the first year your interest rate might be significantly lower.

In general, you’ll be able to deposit money by:

Tick  Using your bank’s mobile app

Tick  Logging into your online account

Tick  Phoning your bank directly

Most banks and building societies will let you withdraw money from your account to transfer it into another account you hold – but remember to check if you’ll lose your allowance or tax-free bonus as a result. 

There are different types of ISAs available depending on your circumstances and requirements

Cash ISAs

Cash ISAs

Cash ISAs let you protect your savings from the taxman and depending on the type of cash ISA you open you’ll often be able to access your money easily

Fixed rate

Fixed-rate ISAs

A fixed-term ISA also offers tax-free savings, but you’ll get higher interest rates if you lock the money away and don't withdraw any

Lifetime ISAs

Lifetime ISAs

Lifetime ISAs are designed for people aiming to buy their first home or save for retirement

Stocks and shares ISAs

Stocks and shares ISAs

A stocks and shares ISA gives you tax-free returns on stocks and shares investments, and the investment decisions are taken care of by a fund manager

Self-select ISAs

Self-select ISAs

A self-select ISA is similar to a stocks and shares ISA, however you’ll choose the shares to hold in your ISA rather than a fund manager

Innovative finance ISAs

How many ISAs can I have open at the same time?

You can have a number of ISAs open at the same time, but keep in mind that after the first year your interest rate might be significantly lower.

How can I add money to my ISA?

It will depend on how your bank or building society lets you manage the account, but in general you should be able to deposit money by:

  • Using your bank’s mobile phone app
  • Logging into your account on a web-browser
  • Phoning your bank directly to organise a cash transfer

How can I withdraw money from my ISA?

Most banks and building societies will let you withdraw money from your account to transfer it into another account you hold – however make sure to check whether you might lose your allowance or tax-free bonus as a result.

What is a Junior ISA?

A Junior ISA is an account you can open on the behalf of a child that offers tax-free returns in much the same way as a standard cash ISA – however the child to whom the account belongs won’t be able to access the money until they’re 18. At this point it becomes a full adult ISA and they’ll take full control of the account.

What is a help-to-buy ISA?

Help-to-buy ISAs are no longer available to new customers, however if you opened one before 30 November 2019 you’ll still be able to use it and take advantage of the bonus it offers until November 2029.

They essentially offer a government bonus of £50 for every £200 you save towards a new home – to a maximum of £3,000. 

What are flexible ISAs?

Flexible ISAs allow you to withdraw cash from your ISA at any time and return it by 5 April (so within the same tax year) without losing any of your allowance.

What currencies can I hold in my ISA?

Your ISA will only be able to hold pounds sterling.

Can I consolidate multiple existing ISAs into one account?

Yes – in fact this is recommended for the reason mentioned above. If you transfer funds from previous ISAs into your current one you’ll be able to take advantage of the better interest rate.
