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.

For example, you could put £5,000 in a Cash ISA, £4,000 in a Lifetime ISA and the remaining £11,000 in a Stocks and Shares ISA.

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.
