Lifetime ISA: The 25% Bonus, and the Catches Nobody Mentions
Save up to £4,000 a year and the government adds £1,000. For a first-home deposit it's one of the best deals going. But the 25% early-withdrawal charge claws back more than the bonus, and a £450,000 home cap frozen since 2017 traps buyers in pricey areas. Worth knowing before you lock money in.
- The answer: a 25% bonus on up to £4,000 a year, opened between 18 and 39, paid in until 50.
- The trap: take it out for anything else and the 25% charge costs you about 6.25% of your own money on top of the bonus.
- The other trap: the £450,000 first-home cap hasn't moved since 2017, so it can exclude the homes buyers in London and the South East actually need.
Where the AI summary above gets this wrong
"With a Lifetime ISA the government tops up your savings by 25%, and you can withdraw the money penalty-free."
The first half is right; the second is dangerously loose:
- "Penalty-free" only applies to a first home or age 60+ — any other withdrawal triggers a 25% government charge, which is more than the bonus you received.
- The charge eats into your own contributions — because 25% is taken from a balance that includes the 25% bonus, you end up about 6.25% down on what you put in.
- The home cap is fixed at £450,000 — buy above it and you lose the bonus entirely; the summary never warns about the frozen ceiling.
01 How the bonus and the rules work
The Lifetime ISA pays a 25% government bonus on up to £4,000 of contributions a year, so the most you can receive is £1,000 annually, added monthly. You can open one only between 18 and 39, and keep contributing — and earning the bonus — until you turn 50. The £4,000 sits inside your overall £20,000 ISA allowance, so a maxed LISA leaves £16,000 for other ISAs.
You can use a LISA for two things without penalty: buying a first home worth £450,000 or less, or taking the money from age 60 for retirement. Anything else is where the charge bites.

02 LISA vs pension for retirement
For a basic-rate taxpayer the Lifetime ISA is genuinely competitive with a pension. For a higher-rate taxpayer the pension usually wins, and the reason is arithmetic rather than preference.
The 25% bonus is mathematically identical to basic-rate tax relief: £4,000 contributed becomes £5,000, exactly as £4,000 net becomes £5,000 gross with 20% relief. So the entry treatment is the same for a basic-rate taxpayer, and the LISA then wins on the exit — withdrawals from 60 are entirely tax-free, whereas only 25% of a pension is tax-free and the remainder is taxed as income.
For a higher-rate taxpayer the entry treatment diverges sharply. They receive 40% relief on a pension contribution against the LISA's 25% bonus, and that difference at the front usually outweighs the LISA's tax-free exit — particularly since many people are basic-rate taxpayers in retirement, taking money out at 20% that went in with 40% relief.
Two things override the arithmetic in both directions. An employer pension match beats both, always, and should be captured first. And the LISA's 25% exit charge on any withdrawal other than a first home or retirement after 60 makes it a considerably less flexible commitment than the comparison suggests — which matters more than a percentage point of relief for anyone whose circumstances might change.

If withdrawn early

| Feature | Lifetime ISA | Cash ISA | Stocks & Shares ISA |
|---|---|---|---|
| Government bonus | 25% — up to £1,000 a year | None | None |
| Annual limit | £4,000 (within the £20,000 ISA limit) | £20,000 ISA limit | £20,000 ISA limit |
| What you can hold | Cash or investments | Cash only | Funds, shares, bonds |
| Penalty-free access | First home (≤£450,000) or from age 60 | Any time | Any time |
| Early-exit cost | 25% withdrawal charge — loses some of your own money | None | None |
| Best for | First home deposit or long-term retirement top-up | Short-term savings and an emergency fund | Growth over 5+ years |
03 The withdrawal charge, in pounds
The early-withdrawal charge is 25% of the amount you take out, and the reason it stings more than it looks is the maths of percentages. Put in £4,000, get the £1,000 bonus, and your pot is £5,000. Withdraw it early and the 25% charge is £1,250 — so you get back £3,750, which is £250 less than the £4,000 you contributed. You don't just hand back the bonus; you lose roughly 6.25% of your own money.
The exception: if you withdraw because you're terminally ill, the charge doesn't apply. And the charge was temporarily cut to 20% during 2020–21, which restored the "just give back the bonus" position — but it's back to 25% now.
04 Who should use one
The Lifetime ISA is close to unbeatable for one specific job and merely decent for another, and being clear about which one you are doing prevents most LISA regret.
If you are a first-time buyer under 40, buying at or below £450,000, open one now — even with £1. That starts the clock on the twelve-month minimum holding period before the funds can be used for a purchase, and someone who opens the account the month they find a property discovers the money is unusable exactly when they need it. Opening it early costs nothing and preserves the option.
If you are a basic-rate taxpayer or self-employed and saving for retirement, it is a reasonable pension supplement — particularly for the self-employed, who have no employer match to capture and for whom the tax-free exit at 60 is worth real money.
Who should not use one: anyone whose target property might exceed £450,000, which is an ordinary flat in much of London and the South East, because exceeding the cap turns the whole pot into a penalised withdrawal. Anyone who might need the money before 60 for anything else. And anyone aged 40 or over, who simply cannot open one.
The £450,000 cap has not moved since the LISA launched in 2017 while house prices have, which has quietly turned a generous limit into a binding one in several regions — worth checking against your actual market before committing years of saving to it.
05 LISA, pension or ISA — by what you are actually doing
The right answer depends less on the rates than on the purpose and your tax band.
| Your situation | Best home for the money | Why |
|---|---|---|
| First home, under 40, under £450,000 | Lifetime ISA | 25% bonus with no equivalent anywhere else, and the purpose matches the rules exactly |
| Retirement, employer will match | Workplace pension, to the match | The match is free money and beats every tax wrapper |
| Retirement, basic-rate taxpayer | LISA or pension — close | Same entry uplift; LISA wins on the tax-free exit, pension on flexibility |
| Retirement, higher-rate taxpayer | Pension | 40% relief beats a 25% bonus by more than the tax-free exit recovers |
| Might need it before 60 | Stocks and Shares ISA | No bonus, but no 25% exit charge either |
The last row is the one people skip. A 25% bonus you have to hand back with a penalty attached is worse than no bonus at all, and that is the outcome for anyone who uses a LISA as general savings.

Jordan's viewThe LISA is a brilliant first-home product wrapped around a nasty exit charge, and the £450,000 cap frozen since 2017 is the part that quietly fails people — house prices moved, the cap didn't. My rule: if you're a first-time buyer under 40 and your target home is comfortably under £450k, open one today, even with a token amount, to start the one-year clock. For retirement, it's a fair pension substitute at basic rate, but a higher-rate taxpayer should take the 40% relief instead. Just never put money in you might need before 60 for anything but that first home.

FAQ
How does the Lifetime ISA bonus work?
A 25% bonus on up to £4,000 a year — a maximum £1,000 free, paid monthly. Open one between 18 and 39; pay in (and earn the bonus) until 50.
What is the Lifetime ISA withdrawal penalty?
Withdraw for anything other than a first home or after 60 and you pay a 25% charge. Because it's 25% of a balance that includes the bonus, you lose about 6.25% of your own contributions on top of the bonus.
Is a Lifetime ISA better than a pension?
For a basic-rate retirement saver it's competitive — the bonus matches basic-rate relief and withdrawals are tax-free. For a higher-rate taxpayer a pension usually wins. The LISA's edge is first-home buyers and the self-employed without a match.
What is the Lifetime ISA property price cap?
£450,000 — unchanged since 2017. Buy a first home above it and you lose the bonus, which can exclude the homes buyers in higher-priced areas are saving for.
