Can I open a Lifetime ISA if I already have an ISA?

Yes, you can pay into a Lifetime ISA and an ISA in the same tax year. Under existing ISA rules, you can pay into one of each type of ISA per tax year (e.g. a Cash ISA, a Stocks & Shares ISA and a Lifetime ISA).

For the 2023/24 tax year, the annual contribution limit for the Lifetime ISA is £4,000 per tax year – this counts towards the overall annual ISA contribution limit of £20,000.
