What is a stocks and shares ISA?

A stocks and shares ISA is a tax-free way of investing up to £20,000 each tax year in the stock market through funds, bonds or shares.

It’s different to a cash ISA, which is also tax free but pays interest on your savings.

You can only open one stocks and shares ISA each tax year in the UK.

    Where you purchase a small slice of a single company and look to make a return as the company’s value rises

  • 2

What are the stocks and shares ISA rules?

Tax-free stocks and shares ISAs are governed by a number of rules. These include:

  • Maximum annual investment – save up to £20,000 tax-free in ISAs each tax year. This money can be invested entirely in stocks and shares ISAs or cash ISAs, or split between the two

  • Deadline for investing – the end of the tax year is 5th April. You must use your annual ISA allowance by then or lose it

  • More flexible investing – you can now open as many stocks and shares ISAs, cash ISAs and innovative finance ISAs as you like during the tax year (subject to £20,000 annual subscription limit)

  • Frequency of investing – make a lump sum deposit, regular or occasional contributions throughout the tax year 

  • Reinvesting – if you cash in some or all of your ISA, you can reinvest this money into another ISA, but only to the extent that you have unused available ISA allowances

Our expert says


Stocks and shares ISAs provide a great opportunity. Not only will you benefit from tax-free returns, but the stock market typically outperforms savings accounts, so you can see your money growing faster. There are risks though. As with all investments, the value of what you have can go down as well as up.

You’ll need to be aged 18 or over and a UK resident for tax purposes.

Rule changes mean you can now open as many stocks and shares ISA as you like each tax year. You can also open multiple cash ISAs or innovative finance ISAs in the same tax year but you’ll have to split your annual £20,000 ISA allowance between the different types of account. You are allowed to retain existing ISAs from previous years.

There are two main ways to transfer stocks and investments between trading accounts, either via an ‘in specie’ transfer or as cash.

An ‘in specie’ transfer is known as a stock transfer - that means transferring your assets in their current form whether it’s stocks and shares or unit trusts and mutual funds.

Stock transfers allow you to keep hold of your investments alongside any changes in value. The downside is that it can take up to four weeks to transfer your holdings.

No, the ISA allowance is capped at £20,000 for the current tax year. If you don’t use it by April 5, it expires and is lost. You’ll have a new £20,000 ISA allowance for the next tax year. 

Yes, as with all investments, the value of what you hold can go down as well as up. Historically over the long term, the stock market has outperformed savings accounts. This is why it’s normally advised that you invest in a stocks and shares ISA over the long term.

Both types of ISA offer tax-free returns on £20,000 saved each year, but while a cash ISA is a savings account that pays interest, a stocks and shares ISA sees your money is invested in the stock market.

The length of time you invest is a matter of personal choice and comes down to individual needs and preference. Typically, investing for longer and diversifying your investments gives you more chance to make better returns and ride out any downturns in the stock market.

Investing in stocks and shares is relatively straightforward. There are a few ways you can do it depending on how hands-on you want to be with your investments. Our guide on How to invest in the stock market gives more information.

When you buy shares, you effectively own a small slice of the company you’re investing in.

This depends on many factors, such as how much research you want to do or knowing specific sectors you may want to invest in. Experienced investors may choose to pick stocks themselves. Alternatively, you could opt to have your ISA managed by a fund manager. You’re likely to be charged slightly more for this, but you have a dedicated expert trying to optimise your returns.

It’s not certain that your stocks and shares ISA will perform better than a savings account, but over the long term this has historically proved to be the case. All investments are different though, so it depends when and where you invest compared to the returns you might receive with a savings account.
