LISA Rules — Key Facts

Can I use a LISA if my partner already owns a home?+
No. Both buyers must be first-time buyers to use the LISA bonus for a property purchase. If your partner already owns or has owned a home, you cannot use your LISA for that joint purchase. You could still use your LISA for retirement savings, but the home purchase bonus would not be available.
Is a LISA better than a pension?+
It depends. A LISA bonus is 25% (effectively tax-relief at 20%). A pension gives tax relief at your marginal rate (20%, 40%, or 45%), plus employer contributions through auto-enrolment. For basic rate taxpayers with employer matching, a workplace pension is usually better. The LISA is most valuable as a supplement for first-time buyers, or for the self-employed without employer pension contributions.
What happens to my LISA if I never buy a home and I die before 60?+
On death, the LISA can be closed without the withdrawal penalty — the full balance including the government bonus is paid to your estate. This is an exemption to the usual penalty for unauthorised withdrawals.
