How the Lifetime ISA works
The Lifetime ISA (LISA) was introduced in April 2017 as a savings vehicle for two specific purposes: buying your first home or saving for retirement. You can save up to £4,000 per tax year, and the government adds a 25% bonus — up to £1,000 per year. Your LISA contributions count towards your overall £20,000 annual ISA allowance.
LISAs are available as Cash LISAs (earning interest) or Stocks and Shares LISAs (where your money is invested). You must be aged 18 to 39 to open a LISA, but you can continue contributing until you turn 50.
Who is eligible for a Lifetime ISA?
To open a LISA, you must be aged 18 to 39 and be a UK resident. Once opened, you can keep contributing until you turn 50, even though you cannot open a new one after 39. This means someone who opens a LISA on their 39th birthday can continue contributing for 11 more years.
The 25% government bonus explained
The bonus is paid monthly (typically within four to six weeks of your contribution). If you contribute the full £4,000 in a tax year, you receive a £1,000 bonus. Over the lifetime of a LISA, the maximum bonus from age 18 to 50 is £32,000 — a substantial amount of free money from the government.
The bonus is calculated on contributions only, not on interest or investment growth within the LISA. Both the bonus and any returns within the LISA are tax-free when withdrawn for eligible purposes.
Using your LISA to buy your first home
You can use your LISA savings (including the bonus) towards a deposit on your first home, provided:
- The property costs £450,000 or less
- You buy the property at least 12 months after opening the LISA
- You buy with a mortgage (not outright cash purchase)
- You have never owned a property before (anywhere in the world)
If you are buying with a partner who also has a LISA, you can both use your LISAs towards the same property, effectively doubling the bonus. However, both buyers must be first-time buyers.
Using your LISA for retirement
You can withdraw from your LISA tax-free and penalty-free from age 60. At this point, the LISA functions similarly to a pension but without the income tax charge on withdrawals that pensions carry. The 25% bonus effectively gives you free money for retirement, making it a valuable supplement to your pension.
However, you cannot access pension funds until age 57 (from 2028), while LISA withdrawals are penalty-free only from 60. This means there is a gap of three years where your pension is accessible but your LISA is not.
The withdrawal penalty: the crucial catch
If you withdraw money from your LISA for any reason other than buying your first home or after turning 60, you face a 25% withdrawal penalty. This penalty is applied to the total withdrawal amount, which means you actually lose money — not just the bonus, but some of your own contributions too.
For example, if you contribute £4,000 and receive a £1,000 bonus (total £5,000), then withdraw early, you pay a 25% penalty on £5,000 = £1,250. You get back £3,750 — £250 less than you put in. This makes the LISA unsuitable for general savings where you might need access to the money.
LISA vs pension: which is better for retirement saving?
For basic-rate taxpayers, a LISA and a pension offer broadly similar tax benefits for retirement saving. A pension gives 20% tax relief going in but taxes 75% of withdrawals at your marginal rate. A LISA gives a 25% bonus going in and withdrawals are tax-free from 60.
However, a pension has several advantages: higher contribution limits (£60,000 vs £4,000), employer contributions, and accessibility from age 57 rather than 60. For higher-rate taxpayers, pensions are usually more efficient because the 40% tax relief on contributions exceeds the LISA's 25% bonus.
The LISA works best as a supplement to your pension, not a replacement for it.
Should you open a Lifetime ISA?
A LISA is worth considering if you are under 40 and either saving for your first home (valued at £450,000 or less) or want to supplement your pension savings. The 25% bonus is genuinely valuable — it is hard to find a guaranteed 25% return anywhere else.
However, a LISA is not suitable if you think you might need the money for other purposes, if you are already a homeowner, or if you are a higher-rate taxpayer who would benefit more from additional pension contributions.
