If you're between 18 and 39 and saving for your first home or for later life, the Lifetime ISA (LISA) is one of the most generous accounts the government offers. Save up to £4,000 a year and the state adds a 25% bonus, worth up to £1,000.
But the rules trip people up. There's a 12-month wait before you can buy, a £450,000 property cap, and a withdrawal charge that can take a slice of your own money if you take cash out for the wrong reason.
This guide explains how a LISA works, who it suits, the penalties to avoid, and how it stacks up against a pension. We've written it for self-employed people, contractors and small business owners who don't get an employer pension and want to use their tax-free allowances well.
It's general information, not personal financial advice. We'll show you where a Zmartly accountant fits in at the end.
What is a Lifetime ISA and how does it work? {#what-is-a-lifetime-isa}
A Lifetime ISA is a tax-free savings account designed to help younger adults with two goals: buying a first home, or saving for later life.
The headline feature is the government bonus. For every £4 you pay in, the government adds £1, a 25% top-up on contributions of up to £4,000 a year. That's a maximum bonus of £1,000 each tax year. The bonus and any growth are tax-free.
You can hold cash, stocks and shares, or a combination, inside your LISA. We'll cover the difference below.
If you're self-employed, this matters more than it might for an employee. You don't get an employer pension contribution, so the LISA bonus is one of the few "free money" top-ups available to you, and it sits alongside your other tax planning rather than replacing it.
What are the key Lifetime ISA rules? {#key-lifetime-isa-rules}
The rules are strict, and breaking them is expensive. Here's what you need to know.
Who can open one, and until when?
- You must make your first payment before you turn 40.
- You can keep paying in, and earning the bonus, until you turn 50.
- After 50 you can't add new money, but the account stays open and keeps growing tax-free.
How much can you pay in?
- The maximum is £4,000 per tax year, attracting up to £1,000 in bonus.
- That £4,000 counts towards your overall £20,000 annual ISA allowance, so you can still put up to £16,000 into other ISAs in the same year.
When can you take the money out without a charge?
You can make a charge-free withdrawal in three situations:
- Buying your first home. The property must cost £450,000 or less, you must buy with a mortgage and live there, you must have held the LISA for at least 12 months, and completion is expected within 90 days of the funds being released. Your conveyancer handles the withdrawal with your provider.
- Age 60 or over. From age 60 you can take the money out for any reason with no charge.
- Terminal illness. If you're diagnosed as terminally ill with less than 12 months to live, you can withdraw without a charge.
Take money out for any other reason and you'll pay the withdrawal charge, explained next.
How much could the bonus add to your savings? {#how-much-bonus}

The bonus is the part worth focusing on, because it's fixed and guaranteed in a way that interest rates and investment returns are not.
Illustrative example
Imagine Daniel, a 28-year-old self-employed designer saving for a first home over five years. He pays in the full £4,000 each tax year.
| Item | Amount |
|---|---|
| His own contributions (5 × £4,000) | £20,000 |
| Government bonus (25% of £20,000) | £5,000 |
| Total before any interest or growth | £25,000 |
So before a penny of interest, Daniel has £25,000, of which £5,000 is free money he wouldn't get in an ordinary savings account.
On top of that, a cash LISA pays interest and a stocks and shares LISA can grow (or fall) in value, so his final balance would be higher or lower than £25,000 depending on the account and the markets. The £5,000 bonus, though, is locked in regardless. That's the LISA's real advantage over a standard savings pot.

What is the Lifetime ISA withdrawal charge? {#withdrawal-charge}
If you take money out for any reason that isn't a qualifying first home, age 60+, or terminal illness, you pay a 25% government withdrawal charge on the amount you take out.
Here's why that hurts more than it looks. The charge is 25% of the withdrawal, not just a clawback of the 25% bonus, so it can eat into your own savings.
Illustrative example
Say you've paid in £4,000 and received the £1,000 bonus, giving a £5,000 balance, then withdraw the lot early:
| Item | Amount |
|---|---|
| Balance withdrawn | £5,000 |
| 25% withdrawal charge | £1,250 |
| You receive | £3,750 |
You paid in £4,000 of your own money but get back only £3,750. The charge has removed the bonus and £250 of your own cash. That's the trade-off for the upfront 25% boost: only commit money you're confident you won't need before age 60 or a first home.
This is exactly why we tell clients to keep a separate emergency fund in an instant-access account. A LISA is not the place for money you might need at short notice.
Cash LISA or stocks and shares LISA? {#cash-vs-stocks-shares}
Both types get the same 25% bonus and the same tax-free treatment. The difference is what your money does while it sits there.
| Feature | Cash LISA | Stocks and shares LISA |
|---|---|---|
| Returns | Interest, like a savings account | Investment growth, which can rise or fall |
| Risk | Capital is not exposed to markets | Value can go down as well as up |
| Best suited to | Shorter timescales (buying within ~1 to 5 years) | Longer timescales (10+ years, often retirement) |
| Certainty | You know roughly what you'll have | No guaranteed return |
A simple rule of thumb: if you're buying a home soon, a cash LISA avoids the risk of a market dip at the wrong moment. If retirement is your goal and it's a decade or more away, a stocks and shares LISA gives your money more time to ride out the ups and downs.
You can transfer between the two types, and between providers, without losing the bonus or triggering a charge, as long as you use the official ISA transfer process rather than withdrawing and re-depositing the cash yourself.
The value of investments can fall as well as rise, and you may get back less than you put in. Choosing specific investments is regulated financial advice, which Zmartly doesn't provide.
Is a Lifetime ISA or a pension better for retirement? {#lisa-vs-pension}
For self-employed people without an employer pension, this is the question that matters most. There's no single right answer; it depends on your tax position.
Where the LISA can win
- For basic-rate taxpayers, the 25% LISA bonus is broadly comparable to the 20% pension tax relief on contributions. But LISA withdrawals in later life are completely tax-free, whereas most pension income is taxable when you draw it.
- For earlier access, a LISA opens up at age 60. The normal minimum pension age is currently 55, rising to 57 from 6 April 2028 (already law). Depending on your plans, the access ages may suit you differently.
- For flexibility, the LISA can be used towards a first home before 60, which a pension can't.
Where a pension usually wins
- For higher and additional-rate taxpayers, pension tax relief at 40% (higher rate) or 45% (additional rate) outweighs the LISA's flat 25% bonus.
- For contribution room, the pension annual allowance is £60,000 for 2025/26 (or 100% of your relevant earnings if lower), against the LISA's £4,000 cap. If you want to put away more, a pension has far more headroom.
- For employees with an employer scheme, employer contributions are extra money on top of your own. A LISA has no equivalent.
In practice, for many self-employed clients the sensible answer is "both", in the right order: use the pension for the bigger tax relief and the higher limit, and use the LISA for the flat bonus, the tax-free withdrawals and the first-home flexibility. The right split depends on your income, your goals and your wider tax position, which is precisely the conversation worth having before you commit.
If you're weighing how dividends, salary and savings interact, our self-assessment service and tax advisory service are built for exactly these decisions.
What happens to your LISA if you don't buy a home? {#no-home-purchase}
Plans change, and the LISA is more forgiving here than the old Help to Buy ISA was.
- If you decide not to buy, leave the money where it is and treat it as retirement savings. You can access it with no charge from age 60.
- If you already owned property (anywhere in the world, including an inherited share), you've lost first-time buyer status and can't use the LISA for a home. It still works as a retirement pot.
- If your home costs more than £450,000, you can't put the LISA towards it without the 25% charge. The options are to find a property under the cap, keep the LISA for later life, or pay the charge (rarely worth it).
Renting and living in a parent's home don't affect your first-time buyer status. Owning, or having owned, a property or a share of one does.
Could the Lifetime ISA be replaced? {#future-changes}
This is where you should be careful with anything you read, because nothing here is settled.
At the Autumn Budget 2025, the government said it intends to consult on a new, simpler ISA aimed only at first-time buyers, which could in time replace the Lifetime ISA. A consultation was expected in early 2026. Reporting at the time suggested any new product might not launch before April 2028.
What's important: this is a proposal and a consultation, not enacted law. The rules described in this guide are the rules that apply now. When schemes have closed before, such as the Help to Buy ISA, existing holders kept their accounts and bonuses, but we can't promise the same here because the detail hasn't been decided.
If you open a LISA today, you do so under today's rules. If reform lands, we'll update this page. For the official position, watch announcements from HM Treasury on gov.uk.
Frequently asked questions {#faqs}
How much can I pay into a Lifetime ISA each year?
Up to £4,000 per tax year. The government adds a 25% bonus on top, up to £1,000, so a maxed-out LISA gets £5,000 in for the year before any interest or growth. That £4,000 counts towards your overall £20,000 annual ISA allowance, leaving up to £16,000 for other ISAs.
What happens if I withdraw from my Lifetime ISA early?
You pay a 25% government withdrawal charge on the amount you take out, unless it's for a qualifying first home, you're 60 or over, or you're terminally ill. Because the charge applies to the whole withdrawal, it removes the bonus and a slice of your own money. Withdraw £5,000 and the £1,250 charge leaves you £3,750, which is less than the £4,000 of your own contributions.
Can I have a Lifetime ISA and other ISAs at the same time?
Yes. You can hold a LISA alongside a cash ISA and a stocks and shares ISA. Your total contributions across all of them can't exceed the £20,000 annual ISA allowance, and the LISA portion is capped at £4,000.
Is a Lifetime ISA better than a pension?
It depends on your tax band. For basic-rate taxpayers the 25% LISA bonus is broadly similar to 20% pension tax relief, and LISA withdrawals are tax-free. For higher-rate (40%) and additional-rate (45%) taxpayers, pension tax relief is usually more valuable, and the pension annual allowance of £60,000 for 2025/26 allows much larger contributions than the LISA's £4,000. Many people benefit from using both.
What is the maximum property price for a Lifetime ISA purchase?
£450,000, the same across the whole of the UK. If your first home costs more than that, you can't use the LISA towards it without paying the 25% withdrawal charge.
How long do I need to hold a Lifetime ISA before buying a home?
At least 12 months from your first payment into the account. So open the LISA at least a year before you expect to complete a purchase.
Can my partner and I both use a Lifetime ISA on the same home?
Yes, if you're both first-time buyers you can each use your own LISA towards the same property, as long as it costs £450,000 or less and you've each held your LISA for at least 12 months. Between you, that's up to £8,000 of contributions and £2,000 of bonus in a single tax year.
Talk to a Zmartly accountant
Deciding how much to put into a LISA, how it fits with a pension, and how it interacts with your wider tax position is the kind of planning that pays for itself. It's especially worth getting right if you're self-employed or run a limited company and don't have an employer pension doing the work for you.
