The Lifetime ISA (LISA) was introduced in April 2017 to help people aged 18-39 save for their first home or retirement. The headline attraction is a 25% government bonus on everything you save, up to £4,000 per year. Put in the maximum and the government adds £1,000. Free money — with conditions.
How the Lifetime ISA works
You can save up to £4,000 each tax year into a LISA, and the government tops it up by 25%. The £4,000 counts towards your overall £20,000 ISA allowance. So if you put £4,000 in a LISA, you have £16,000 left for other ISAs that year.
The bonus is paid monthly, usually within 4-6 weeks of each deposit. Over years of saving, the compounding effect of the bonus plus interest or investment returns can be substantial. Save the maximum for five years and you'll have £25,000 of your own money plus £5,000 in bonuses — before any growth.
Cash LISA vs Stocks and Shares LISA
Just like regular ISAs, LISAs come in two flavours. A Cash LISA earns interest like a savings account. A Stocks and Shares LISA invests your money in funds or individual investments. If you're saving for a house purchase within the next few years, a Cash LISA is generally safer. If retirement is your goal and you won't touch the money for decades, investing gives your money more potential to grow.
Using a LISA to buy your first home
This is where most people's interest lies. You can use your LISA savings (including the bonus) towards buying your first home, provided certain conditions are met:
The property must cost £450,000 or less. This limit hasn't changed since the LISA launched, which makes it increasingly challenging in parts of London and the South East. If you find a property at £455,000, you can't use any of your LISA funds for that purchase without triggering the penalty.
You must have had the LISA open for at least 12 months. Even if you only put in £1, open the account as soon as possible to start the clock ticking. This catches out plenty of first-time buyers who leave it too late.
You must be a first-time buyer. That means you've never owned a property anywhere in the world. If you're buying with someone who already owns or has owned a property, you can still use your LISA but they cannot use theirs.
The purchase must be with a mortgage. You can't use a LISA to buy a property outright with cash.
Your solicitor handles the LISA withdrawal during the conveyancing process. The money goes directly to them, not to you. Allow plenty of time — LISA withdrawals for property purchases can take several weeks.
Using a LISA for retirement
You can withdraw from your LISA penalty-free after age 60. At that point, all withdrawals — your savings, the government bonus, and any growth — are completely tax-free. This makes the LISA a genuinely attractive retirement option, especially compared to a pension where only 25% is typically tax-free.
However, you can only contribute between ages 18 and 50, so there's a finite window. The maximum you could save is 32 years × £4,000 = £128,000 of your own money, plus £32,000 in bonuses, plus growth.
The withdrawal penalty
Here's where things get painful. If you withdraw money for any reason other than buying a qualifying first home or after turning 60, you face a 25% penalty on the total amount withdrawn. Because the penalty is calculated on the total (your money plus the bonus), you actually lose more than just the bonus.
Quick example: you put in £1,000, the government adds £250, giving you £1,250. Withdraw early and the 25% penalty is £312.50. You get back £937.50 — that's £62.50 less than you put in. You've effectively lost 6.25% of your own money.
The penalty was temporarily reduced to 20% during the COVID pandemic, but it's back to 25%. There's an exception for terminal illness — if you're diagnosed with less than 12 months to live, you can withdraw without penalty.
LISA vs Help to Buy ISA
The Help to Buy ISA closed to new applicants in November 2019. If you already had one, you could keep saving into it until November 2029, but the bonus must be claimed by November 2030. You cannot hold both a Help to Buy ISA and a LISA and claim both bonuses for the same property purchase. The LISA is generally the better option because the bonus is larger (£4,000 vs £3,400 per year) and you receive it as you go rather than at completion.
LISA vs pension for retirement
Both offer tax advantages, but they work differently. Pension contributions get tax relief at your marginal rate — 20% for basic rate taxpayers (effectively the same as the LISA bonus), 40% for higher rate taxpayers (much more generous than the LISA). But pension withdrawals are taxed as income, while LISA withdrawals after 60 are tax-free.
For basic rate taxpayers, the choice is roughly even. For higher rate taxpayers, pensions are usually better because of the higher upfront relief. For everyone, employer contributions to workplace pensions tip the scales heavily in the pension's favour — your employer doesn't match LISA contributions.
The pragmatic approach for many people is to contribute enough to their workplace pension to capture the full employer match, then use a LISA for additional saving if they're eligible.
Where to open a Lifetime ISA
Several providers offer LISAs. For Cash LISAs, Moneybox and Skipton Building Society are popular choices. For Stocks and Shares LISAs, AJ Bell, Hargreaves Lansdown, and Moneybox all offer options with varying fee structures. Compare platform fees carefully — over decades, a difference of 0.25% in annual charges compounds significantly.
