How much can I invest in an ISA?

Each tax year there's a limited amount of money you can put in an ISA. This limit is set by the government and is called the ISA allowance. In the 2021/2022 tax year, the allowance is £20,000 . You can split the ISA allowance across different types of ISAs, but you can only add money to one ISA of each type in a tax year. Lifetime ISA works differently – read more in our Lifetime ISA section . It's a good idea to use as much of the ISA allowance as you can, because that way you'll be making the most of the ISA tax break for your money.

ISA Allowance 2024/2025

Important information: Investing for longer increases the likelihood of positive returns. Over a period of five years or more, investments usually give you a higher return compared to cash savings. But investments can go down as well as up in value, so you could get back less than you put in.

This isn’t personal advice – please ask us for advice if you’re not sure which investments are right for you. ISA and tax rules can change and benefits depend on your circumstances.

The ISA allowance this tax year is £20,000

You're free to split your ISA allowance any way you like across a Stocks and Shares ISA, Cash ISA, Lifetime ISA (maximum of £4,000) and an Innovative Finance ISA, as long as you stay within the overall limit.

The allowance is smaller for Junior ISAs. The limit this tax year is £9,000.

The tax year runs from 6 April to 5 April, and the deadline for adding money is midnight 5 April.
