What this means
A Lifetime ISA lets 18–39 year-olds save up to £4,000 a year towards a first home or retirement, and the government adds a 25% bonus — up to £1,000 each tax year. You can pay in until age 50. Withdraw for a first home worth up to £450,000 or from age 60 and it's tax-free; take money out for any other reason and a 25% charge applies, which can leave you with less than you paid in.
Frequently asked questions
The government adds 25% on top of what you pay in, up to £1,000 a year. Pay in the full £4,000 annual limit and you get the maximum £1,000 bonus, paid monthly.
You can open a Lifetime ISA if you're aged 18 to 39. Once open, you can keep paying in and earning the bonus until the day before you turn 50. The £4,000 you save counts towards your overall £20,000 ISA allowance.
If you withdraw before age 60 for anything other than buying your first home (up to £450,000), you pay a 25% government charge on the amount taken out. Because the charge applies to your bonus and contributions, you can get back less than you originally paid in.
It must be your first home, cost £450,000 or less, be bought with a mortgage, and the account must have been open for at least 12 months. Both first-time buyers in a couple can each use their own LISA towards the same property.
