How much can I save in a Lifetime ISA?
You can save up to £4000 per year in a LISA and receive a £1000 government bonus on top. If you open a LISA at 18 and contribute the maximum until age 50 you would have contributed £128000 received £32000 in government bonuses and potentially earned significant investment returns on top. The LISA counts toward your overall £20000 annual ISA allowance.
Can I use a LISA and Help to Buy ISA together?
The Help to Buy ISA closed to new accounts in November 2019 but if you have both you can only use the government bonus from one of them for a property purchase. You can still use the savings from both but only claim the bonus from your LISA or Help to Buy not both. Most advisors recommend choosing the LISA bonus as it is more generous.
What happens if I withdraw early from a LISA?
Withdrawing from a LISA for any purpose other than buying your first home or after age 60 incurs a 25% penalty on the total withdrawal amount. This effectively means you lose the government bonus plus an additional amount. For example withdrawing £1000 would cost you £250 in penalties leaving you with £750 which is less than your original £800 contribution.
