How the Lifetime ISA works

A Lifetime ISA (LISA) is a tax-free savings or investment account for people aged 18 to 39. You can pay in up to £4,000 a year (which counts towards your overall £20,000 ISA allowance), and the government adds a 25% bonus — up to £1,000 a year — paid monthly. The pot is for one of two goals:

  • A first home costing up to £450,000, after the account has been open at least 12 months.
  • Retirement, withdrawn tax-free from age 60.
Yearly contributionAnnual bonus
£1,000£250
£2,000£500
£4,000 (max)£1,000
Mind the withdrawal charge. Take money out for any reason other than a first home or retirement after 60 and you pay a 25% charge on the whole amount. Because 25% of the bonus-inflated total is more than the 25% bonus you received, you can get back less than you put in.

LISA vs pension vs ISA

For a first home, the LISA's bonus is hard to beat. For retirement, a workplace pension with employer matching usually wins, but a LISA can be a useful tax-free top-up. Compare a standard tax-free wrapper on the ISA calculator, the pension route on the pension contribution calculator, and general growth on the compound interest calculator.

25% of your contributions, up to £1,000 a year. Pay in the £4,000 maximum and the government adds £1,000.

Can I use a Lifetime ISA to buy a house?

Yes — towards a first home up to £450,000, once the account has been open 12+ months. You can also keep it for retirement and withdraw tax-free from 60.

Is there a penalty for withdrawing early?

Yes — a 25% charge for any withdrawal other than a first home or retirement after 60. This can leave you with less than you paid in.
