No, you cannot pay more than £4,000 into a Lifetime ISA in a single tax year. £4,000 is the hard annual cap set by HMRC, and any contributions over that figure are returned by your LISA provider with no government bonus paid on the excess. Here are all the LISA limits in one place, and the easy ways to accidentally trip them.
HMRC sets the Lifetime ISA contribution limit at £4,000 per tax year. The 2026/27 tax year runs from 6 April 2026 to 5 April 2027. The cap covers the total of every payment you make into the LISA in that period, lump sums, monthly direct debits, and ad-hoc transfers all count.
The 25% government bonus is paid on top of your £4,000, so the maximum that can land in the LISA from your contribution alone is £5,000 (£4,000 personal + £1,000 bonus), before any interest or investment growth.
The limit did not move on 6 April 2026, and it is not due to move for a while: the government has said the Lifetime ISA subscription limit stays at £4,000 until 5 April 2031, alongside the £20,000 overall ISA limit and the £9,000 Junior ISA limit. So if you are planning several years ahead, £4,000 a year is the number to work with.
To see exactly how the £4,000 cap and bonus combine over time, use our LISA bonus calculator. For what the account actually is and who can open one, see the Lifetime ISA explained.
The £4,000 LISA cap is part of the overall £20,000 annual ISA allowance, not separate from it. If you pay the maximum £4,000 into a LISA, you have £16,000 left to use across cash, stocks & shares, and innovative finance ISAs in the same tax year. There is a fuller walk-through in does a Lifetime ISA count towards your ISA allowance.
| Allowance | 2026/27 limit |
|---|---|
| Overall ISA allowance | £20,000 |
| Lifetime ISA (sub-cap) | £4,000 |
| Junior ISA (separate) | £9,000 |
| LISA government bonus | £1,000 (max, 25% of £4,000) |
The 25% government bonus is paid on top and does not count toward the £20,000 ISA limit.
Two age boundaries control LISA contributions:
Practical implication: if you open a LISA at 18 and contribute £4,000 every year until you turn 50, total bonuses would be £32,000 to £33,000 (£1,000 for each tax year you can contribute in), before any growth. You get the higher figure only if your birthday falls late enough in the tax year to fit in one extra full contribution before you turn 50.
Most UK LISA providers (including Moneybox, AJ Bell, Hargreaves Lansdown, Nutmeg, Beehive Money) actively block payments that would breach the £4,000 cap. The check usually runs in real time at the point of contribution.
If a contribution does slip through, for example, if you have multiple LISAs across providers in the same tax year (which itself breaches HMRC’s ‘one LISA per year’ rule):
It is your responsibility to track contributions across providers if you have transferred between LISAs mid-year. The best safeguard is to view the current tax-year contribution figure in the LISA app before each payment.
You can own multiple LISAs, but you can only contribute to one LISA per tax year. Transfers between providers do not breach this rule. If you opened a LISA in 2025/26 with one provider and switched to another for 2026/27 contributions, that is fine, the old LISA can stay open and continue to earn interest, you just cannot pay new money into it.
The same restriction applies to the regular ISA family: one cash ISA, one stocks & shares ISA, one innovative finance ISA, and one LISA per tax year for new contributions.
Unused LISA allowance does not roll over. If you contribute only £1,000 in 2026/27, you cannot pay £7,000 next year, the 2027/28 cap is still £4,000. The same applies to the £1,000 bonus: any unclaimed bonus from a previous year is gone.
This is one reason savers often set a monthly direct debit of £333 (which contributes £3,996 across 12 months and earns £999 in bonus). For more on bonus mechanics, see how the LISA government bonus works, and for how long the money then takes to appear, see when the government pays your LISA bonus.
Nothing is lost by paying in less than the cap. The bonus is 25% of whatever you actually contribute, so a smaller contribution still earns a bonus, just a proportionally smaller one. There is no minimum contribution, no penalty for paying in nothing at all in a given year, and no requirement to keep the direct debit running. The only cost of a quiet year is the bonus you did not claim in it.
Not for the 2026/27 tax year. The £4,000 limit, the 25% bonus, the £1,000 annual bonus cap, the £450,000 property cap and the 25% early withdrawal charge are all exactly as they were in 2025/26.
There is a longer-term consultation running, though, and it is worth knowing about if you are opening an account now. On 23 June 2026 the government published a consultation on a First Time Buyer ISA, proposed to be offered in place of the Lifetime ISA. It closes at 11:59pm on 18 August 2026. As set out in the consultation, the new account would pay its bonus at the point of purchase, would carry no withdrawal charge, and would have no upper age limit, with the bonus rate and contribution limits to be announced at a future fiscal event.
None of this is law. No start date has been set, the Lifetime ISA can still be opened until the replacement is available, and people who already hold a LISA can carry on saving into it under the existing rules. The charge that applies today is still the 25% one described in the LISA withdrawal rules.
LISA limits, age rules, and bonus mechanics can change at any Budget. Kvanta covers every announcement in plain English.

£4,000 personal contribution, plus £1,000 government bonus = £5,000 maximum added per tax year, before interest or growth. The £4,000 figure is unchanged for 2026/27 and is set to stay at that level until 5 April 2031.
Yes. £4,000 to a LISA leaves £16,000 for other ISAs in the same year. The bonus is paid on top.
18–39 to open. Contributions and bonus until age 50. After 50, the LISA stays open and grows but accepts no new money.
Most providers block over-cap contributions automatically. If one slips through, the excess is returned and no bonus is paid. Check your in-app tax-year contribution before each payment.
