The Lifetime ISA (LISA) is one of the government’s most generous savings incentives — a 25% bonus on every pound you save, up to £4,000 per year. This guide explains exactly how the bonus is calculated, when you can access your money, and how the LISA compares with other first-home and retirement saving options.

How the Lifetime ISA bonus works
| Contribution | Government bonus (25%) | Total in account |
|---|---|---|
| £1,000 | £250 | £1,250 |
| £2,000 | £500 | £2,500 |
| £3,000 | £750 | £3,750 |
| £4,000 (maximum) | £1,000 | £5,000 |
The bonus is added automatically — you do not need to claim it. It is paid monthly (for most providers), and it earns interest or investment returns alongside your own contributions.
Annual limit: £4,000 per tax year
Annual bonus maximum: £1,000
Lifetime bonus maximum: £33,000 (if you open at 18 and contribute the maximum until age 50)
Bonus over time: the long-term picture
| Years contributing £4,000/year | Total contributed | Total bonus earned | Total value (ex-investment growth) |
|---|---|---|---|
| 5 years | £20,000 | £5,000 | £25,000 |
| 10 years | £40,000 | £10,000 | £50,000 |
| 20 years (from age 18 to 38) | £80,000 | £20,000 | £100,000 |
| 32 years (from age 18 to 50) | £128,000 | £32,000 | £160,000 |
These figures are before investment growth. A Stocks and Shares LISA invested in a globally diversified fund could grow the balance significantly over 20–30 years.
Using a LISA to buy your first home
The LISA is specifically designed to help first-time buyers get onto the property ladder. The rules:
| Requirement | Detail |
|---|---|
| Property price limit | £450,000 or less |
| Who can use it | First-time buyer only |
| Account age | LISA must have been open at least 12 months |
| How it is used | Funds transferred directly to conveyancer at completion |
| Joint purchase | Both buyers can use their own LISA |
Example: A couple both aged 26, each with a LISA open for 3 years and each contributing £4,000/year:
- Each person: £12,000 contributed + £3,000 bonus = £15,000 per LISA
- Combined: £30,000 available for deposit from LISA alone
If each LISA is also invested and earns 5% annually over 3 years (rough estimate), the combined value could be closer to £32,000–£33,000.
The 25% withdrawal penalty explained
If you withdraw money for an ineligible reason, a 25% withdrawal charge applies to the total balance (contributions + bonus).
Why this is worse than it sounds:
- You contribute £4,000 and receive a £1,000 bonus → balance is £5,000
- A 25% charge takes £1,250 from £5,000 → you receive £3,750
- You put in £4,000 and get back £3,750 — a net loss of £250 on your own money
This is not a bug, it is intentional — the LISA is meant to be locked away for a specific purpose. The penalty acts as a disincentive to treat it as a general savings account.
Eligible withdrawal reasons (no penalty):
- Buying a qualifying first home
- Turning 60
- Terminal illness
Ineligible reasons (25% penalty applies):
- Emergencies
- Buying a second property or a property over £450,000
- Early retirement before 60 (unless terminally ill)
LISA vs pension: which to prioritise?
| Feature | Lifetime ISA | Workplace pension |
|---|---|---|
| Government top-up | 25% bonus | 20%–45% tax relief |
| Employer contributions | None | At least 3% (auto-enrolment) |
| Access age | 60 (or first home) | 57 (rising from 55) |
| Annual limit | £4,000 | £60,000 |
| Penalty for early access | 25% charge | No — just tax on withdrawals |
| Counts towards ISA allowance | Yes | No |
The general rule: If you have a workplace pension with employer contributions, prioritise contributing enough to get the full employer match first — it beats the LISA bonus on a pound-for-pound basis. The LISA is then best used as a first-home savings vehicle or as a secondary retirement savings tool after maximising employer-matched pension contributions.
Cash LISA vs Stocks and Shares LISA
| Type | Best for | Risk | Returns |
|---|---|---|---|
| Cash LISA | Buying a home in the next 1–5 years | Low | Savings interest (current accounts typically 3–5% AER) |
| Stocks and Shares LISA | Retirement savings or long-term first-home saving (5+ years) | Higher | Potential for inflation-beating growth over time |
For a house purchase within a few years, a Cash LISA protects your balance. For longer time horizons, a Stocks and Shares LISA can significantly outperform the bonus on a cash LISA.
