Risk warning
The value of your investments can go down as well as up and you may get back less than you paid in. Laws and tax rules may change in the future. Your own circumstances and where you live in the UK also have an impact on tax treatment.

You can have more than one, but you can only open one of each Individual Savings Account (ISA) type in the same year and there are a few things you should keep in mind.

First, what are the different kinds of ISA?

There are four main kinds of ISA:

  • Cash ISAs: These are similar to a regular savings account, but you don’t pay tax on any interest earned
  • Stocks and Shares ISAs: These allow you to invest your money in funds and other types of investments. One of the main benefits of a Stocks and Shares ISA is that you don’t pay tax on any investment growth
  • Lifetime ISAs: These are specifically for those saving for a first home or life after retirement. The government pays in an extra £1 for every £4 you save. You can save up to £4,000 a year into a Lifetime ISA (£5,000 if you include the government contributions). To invest in a Lifetime ISA, you must be under 40, and can make contributions up to your 50th birthday
  • Junior ISA: This is a long-term savings account set up by a parent or guardian, specifically for their child's future. Only the child can access the money, and only once they turn 18

Next, you need to know how much you can save into an ISA

You can only put a set amount into ISAs each tax year – for the 2022/2023 tax year it’s £20,000. You can split that amount across Cash or Stocks and Shares ISAs any way you choose.

If you’re able to invest into a Lifetime ISA, this has a £4,000 annual investment limit, which counts towards your £20,000 total. So you can split your allowance in a way that makes most sense for you and your financial goals.

Any money invested in a Junior ISA has its own limit of £9,000 (2022/2023). It doesn't count towards the £20,000 limit for your own ISA.

So how many can you have?

You can only open one of each ISA type in the same tax year. For example, you can’t open two Stocks and Shares ISAs in a tax year, but you could open one Stocks and Shares ISA and one Cash ISA.

If you do open more than one ISA, keep in mind that you can’t put in more than £20,000 across all of them in one tax year.

How do you know which one is right for you?

It ultimately depends on what your goal is. It’s also a good idea to consider what your attitude to risk is and what timeframe you’re looking to save over.

For example, if your goal is to grow the value of your money over a longer period of time, then you might want to consider a Stocks and Shares ISA. This is because investing will give your money a greater chance of growing over time than, say, a Cash ISA. However, the value of investments can go down as well as up and you may get back less than was paid in, which isn't the case in a Cash ISA.
