LISA Explained
The Lifetime ISA gives you a 25% government bonus. Here's how to qualify, the limits, and the withdrawal penalty trap.
The Lifetime ISA (LISA) is one of the most generous government incentives in UK personal finance. Put in up to £4,000 per year, and the government adds 25% — up to £1,000 of free money annually. But the rules are strict, and getting them wrong is expensive.
The 25% bonus
For every £1 you contribute, the government adds 25p. Contribute the full £4,000 in a tax year and you get £1,000 added to your pot — automatically. Both your contributions and the bonus then grow tax-free inside the wrapper.
| Annual contribution | Government bonus | Total invested |
|---|---|---|
| £1,000 | £250 | £1,250 |
| £2,000 | £500 | £2,500 |
| £3,000 | £750 | £3,750 |
| £4,000 | £1,000 | £5,000 |
Who can open a LISA?
- •You must be aged 18–39 to open one
- •You can continue contributing until the day before your 50th birthday
- •You must be a UK resident
- •You must not already own a home (for first-home use)
The two permitted uses
Buying your first home
You can use your LISA to buy a first home as long as the property costs no more than £450,000, you are a first-time buyer, and you have held the LISA for at least 12 months. The money goes directly to your solicitor — you cannot withdraw it yourself.
Retirement from age 60
From your 60th birthday you can withdraw everything — your contributions, the government bonus, and all growth — completely tax-free, for any purpose.
The withdrawal penalty trap
If you withdraw for any other reason, HMRC charges a 25% penalty on the full withdrawal amount — including the bonus. Because the penalty is calculated on a pot that already includes the 25% bonus, it effectively claws back all of the bonus and takes an additional ~6.25% of your own contributions.
Example: You pay in £4,000, the government adds £1,000 (total: £5,000). If you withdraw early, the 25% penalty is £1,250 — you get back only £3,750. You have lost £250 of your own money, not just the bonus.
LISA vs pension for retirement saving
For basic-rate taxpayers, the LISA bonus (25%) and pension tax relief (20% basic rate) are mathematically similar for retirement saving. However, pensions benefit from employer contributions under auto-enrolment, which is free money a LISA cannot replicate. Higher-rate taxpayers almost always get better value from pension contributions (40% relief vs 25% LISA bonus).
If you are under 40 and saving for your first home, a LISA is one of the best tools available. If you are saving purely for retirement, max your workplace pension match first.
