Lifetime ISA FAQ
Everything you need to know about Lifetime ISAs, the 25% government bonus, and using your savings for a first home or retirement.
A Lifetime ISA is a UK government-backed savings account designed to help people save for either their first home or retirement. You can save up to £4,000 per year, and the government adds a 25% bonus (up to £1,000 per year). The account must be opened between ages 18 and 39.
The government adds a 25% bonus on your contributions. For every £4 you save, the government adds £1. The maximum annual contribution is £4,000, so you can receive up to £1,000 in government bonus per tax year. The bonus is typically paid monthly based on your contributions.
Yes, you can use your LISA savings plus bonus to buy your first home, provided the property costs £450,000 or less, you intend to live in it (not rent it out), you have a residential mortgage, and your LISA has been open for at least 12 months. The money is paid directly to your conveyancing solicitor.
If you withdraw your LISA savings for any reason other than buying a first home or retirement (after age 60), you’ll pay a 25% government withdrawal charge. This effectively reclaims the government bonus plus a small penalty. There are exceptions for terminal illness.
You can access your LISA for retirement once you reach age 60. At that point, you can withdraw your savings and bonus tax-free. If you don’t need it for a first home, the money continues to grow until retirement age.
The Help to Buy ISA closed to new applicants in November 2019. If you have an existing Help to Buy ISA, you can transfer it into a LISA. You cannot hold both at the same time for the same purpose, but you can have a LISA alongside a Help to Buy ISA you opened before it closed.
