What is the Stocks and Shares ISA allowance?

The 2020-21 tax year allowance is £20,000. This is the total amount you can invest in ISAs during this tax year without paying any tax on the gains.

How does the ISA allowance work?

The allowance can be split between different accounts, including a Cash ISA, Stocks and Shares ISA, Lifetime ISA (up to £4,000) and Innovative Finance ISA. You can contribute to more than one type of ISA, but not to more than one of the same type in the same tax year.

There is a separate allowance for Junior ISAs for under 18s, which is £9,000 for this tax year. 

The current tax year runs from 6 April 2020 to 5 April 2021.

What happens if I do not use my ISA allowance? 

You cannot carry over any ISA allowance if you have not contributed your full amount.

If you do not contribute to your ISA at all during the tax year, you may need to reactivate your ISA the next time you want to make contributions. You can do this by logging in to your account and reconfirming your date of birth and National Insurance number.

When your money is held in an ISA, you don’t pay tax on anything that money earns – be that in the form of interest, dividends or capital gains. ISAs can play an important part in retirement planning alongside pensions.

In addition to the tax advantages, ISAs offer investors flexible access to their savings. It’s important to use as much as you can of your annual £20,000 ISA allowance before the end of the tax year on 5 April, or you will lose it.

ISA allowance FAQs

It is not possible to overpay into your ii ISA, as we limit your total contributions to £20,000 per tax year.

You could accidentally exceed the limit by opening two Stocks and Shares ISAs in the same year (which is not allowed). If this happens, HMRC should be in touch with you after the end of the tax year to advise on next steps.
 

Yes, you can inherit your spouse or civil partner’s ISA allowance if they die. You will have the choice to increase your own allowance by either the value of their ISA when they died, or by the value of their ISA when the account is closed.

When you die, your spouse or civil partner will inherit your ISA. They can either inherit the value of the ISA upon your death, or when it is closed – their own ISA allowance will be unaffected.

If you die without having a spouse or civil partner, your ISA will form part of your estate and be subject to inheritance tax.
