It’s important to note that Lifetime ISAs are not flexible, so it will not be possible for withdrawals to be made and replaced without affecting your annual Lifetime ISA allowance. You can withdraw money from your Lifetime ISA if you’re buying your first home, aged 60 or over, or terminally ill, with less than 12 months to live.
If you close your Lifetime ISA after you reach the age of 40 you will not be able to open a new one.
If you make a withdrawal for any other reason (also known as an unauthorised withdrawal), you will be charged 25%. This recovers the government bonus gained on your original savings.
For example, assuming no growth, initial savings of £800 will earn a 25% government bonus of £200 and give you a Lifetime ISA pot of £1,000. If you wish to make an unauthorised withdrawal, you will be charged 25% of the pot, in this case £250, alongside your withdrawal. You should therefore take the withdrawal charge into account when requesting funds.
