Lifetime ISA Rules UK: What You Can and Can't Do

The Lifetime ISA (LISA) offers a 25% government bonus on contributions up to £4,000 per year. You must be aged 18 to 39 to open one. Withdrawals before age 60 trigger a 25% penalty unless you're buying your first home.

Who Can Open a Lifetime ISA

You can open a Lifetime ISA if you're a UK resident aged between 18 and 39. You must open the account before your 40th birthday, though once it's open you can keep contributing until you're 50.

If you turn 40 tomorrow and haven't opened a LISA yet, you've missed the window. If you opened one at 39, you can contribute for another eleven years.

You can only pay into one Lifetime ISA per tax year, though you can hold more than one if you've switched providers or opened accounts in different years. The contribution limit applies across all your LISAs combined.

Non-UK residents cannot open a new LISA, but if you move abroad after opening one, check your provider's terms—some allow you to keep contributing, others freeze the account.

Contribution Limits and the Government Bonus

The maximum you can pay into a Lifetime ISA is £4,000 per tax year (6 April to 5 April). The government adds a 25% bonus on every contribution you make before you turn 50, which means up to £1,000 in free money each year.

If you contribute £4,000, you receive £1,000 as a bonus. If you contribute £2,000, you receive £500. The bonus is paid monthly or quarterly depending on your provider, usually within six to eight weeks of your contribution.

The £4,000 LISA limit sits inside the overall ISA allowance, which is £20,000 for the 2024/25 tax year. You could put £4,000 in a LISA and £16,000 in a stocks and shares ISA, or split it differently across cash ISAs and other ISA types. Check GOV.UK's ISA guidance for the current allowance.

You can contribute as a lump sum or in monthly payments. The bonus applies to both. Some investors prefer monthly contributions to smooth out stock market volatility if they hold a stocks and shares LISA.

Withdrawal Rules: When You Can Access Your Money

You can withdraw from a Lifetime ISA without penalty in two situations: buying your first home, or reaching age 60. Any other withdrawal incurs a 25% penalty on the amount you take out—not just on the bonus.

The penalty sounds like it simply removes the bonus, but the maths doesn't work that way. If you contribute £4,000 and receive a £1,000 bonus, you have £5,000. A 25% penalty on £5,000 is £1,250, so you'd get back £3,750—less than you put in.

Example: You've contributed £10,000 over several years and received £2,500 in bonuses. Your balance is £12,500. If you withdraw before 60 and not for a first home, you pay a 25% charge on £12,500 (£3,125), leaving you with £9,375. You've lost £625 of your own money.

There are limited exceptions to the penalty. You can withdraw without charge if you're terminally ill with less than 12 months to live, as confirmed by a medical professional. This exception requires documentation from your doctor.

Once you turn 60, you can withdraw as much as you like, whenever you like, with no penalty. The money remains tax-free. You don't have to buy an annuity or take the whole sum at once—it works like any other ISA after that point.

Using a Lifetime ISA to Buy Your First Home

To use your LISA for a first home purchase, the property must cost £450,000 or less. This limit applies across the whole of the UK. A £450,001 house disqualifies you—there's no flexibility.

You must be a first-time buyer, defined as someone who has never owned residential property anywhere in the world. If you owned a flat in another country ten years ago, you don't qualify. If you inherited a share of a property, that typically counts as ownership.

The property must be in the UK. You cannot use a LISA to buy abroad. It must also be the home you intend to live in—buy-to-let purchases don't qualify.

You need to have held the LISA for at least 12 months before you can use it for a house purchase. If you open it in April 2024, you can't complete a purchase using those funds until April 2025. Contributions made in month one still count, but the account must have been open for a full year.

Your solicitor or conveyancer requests the funds directly from your LISA provider. You don't withdraw the money yourself. The provider transfers the full balance—your contributions, the government bonus, and any investment growth—to your solicitor in time for completion. This process can take several weeks, so inform your solicitor early.

If you're buying with a partner who also has a LISA, you can both use your funds for the same property, as long as you each meet the first-time buyer criteria. Two people could combine up to £66,000 in contributions and bonuses (assuming maximum contributions from age 18 to 40).

Once you've used your LISA to buy a home, you can keep the account open and continue contributing if you're under 50. The money then becomes accessible only at age 60.

Lifetime ISA vs Help to Buy ISA

The Help to Buy ISA closed to new applicants in November 2019, but existing holders can keep contributing until November 2029. You cannot open both a LISA and a Help to Buy ISA in the same tax year, though you can hold both if opened in different years.

You can only use one of these accounts to buy a single property. If you have both, you need to decide which offers the better bonus for your circumstances. The Help to Buy ISA pays a 25% bonus on up to £12,000 of savings (maximum £3,000 bonus), but you receive it only at completion.

The LISA allows higher contributions (£4,000 per year versus £200 per month after an initial £1,000 in the Help to Buy ISA) and pays the bonus as you go. For most savers, the LISA provides a larger total bonus, but if you're close to buying and already hold a Help to Buy ISA with substantial savings, the calculation depends on your timeline.

You can transfer a Help to Buy ISA into a Lifetime ISA without penalty. The transferred amount counts towards your LISA contribution limit for that tax year. If you transfer £4,000 from a Help to Buy ISA, you've used your full £4,000 LISA allowance and can't add more until the next tax year.

Tax Treatment and Investment Options

Money inside a Lifetime ISA grows free from income tax and capital gains tax. You don't pay tax on dividends from shares, interest from cash, or gains when you sell investments. When you withdraw at 60 or for a first home, the withdrawal is also tax-free.

Lifetime ISAs come in two types: cash and stocks and shares. A cash LISA works like a savings account—you earn interest, and the rate depends on the provider. A stocks and shares LISA lets you invest in funds, shares, or bonds, and the value can go up or down.

If you're buying a home within five years, a cash LISA is usually safer because you won't risk a market drop just before you need the money. If you're saving for retirement at 60, a stocks and shares LISA gives you decades to ride out volatility and potentially grow your money faster than cash interest.

You can transfer between providers or switch from cash to stocks and shares (or vice versa) without losing the bonus or triggering the withdrawal penalty. Transfers don't count towards your annual contribution limit. Most providers handle the transfer process for you, though it can take several weeks.

Some platforms charge annual fees for managing a stocks and shares LISA—check the cost before you invest. Fees of 0.25% to 0.45% per year are common. On a £10,000 balance, that's £25 to £45 annually. Weigh this against the £1,000 bonus to see if it's still worthwhile.

What Happens If You Move Abroad or Die

If you become non-UK resident, you can usually keep your LISA open but may not be able to contribute, depending on your provider's rules. Some platforms allow continued contributions from abroad; others don't. The government bonus eligibility depends on your tax residency status—check the terms with your provider and HMRC.

If you die, your LISA forms part of your estate. The account doesn't incur the withdrawal penalty. Your beneficiaries receive the full balance—all contributions, bonuses, and growth—though the money may be subject to inheritance tax if your estate exceeds the nil-rate band (£325,000 for 2024/25, or more if you qualify for the residence nil-rate band).

The LISA doesn't receive the same spousal exemption that pensions enjoy. If you're married, your spouse inherits the cash value but can't absorb it into their own LISA without it counting against their annual limit.

Common Mistakes to Avoid

Opening a LISA at 39 and 364 days still counts—you don't need months of runway. But if you think you might need the money before 60 and aren't certain you'll buy a qualifying first home, the penalty is harsh.

Don't assume you can open a LISA, change your mind, and withdraw penalty-free. The 25% charge applies immediately if you don't meet the exemption criteria. This isn't a flexible savings account.

Remember the 12-month rule for home purchases. Opening a LISA the week before you plan to buy won't work—you need a full year of holding time before the funds become available for property.

Check the £450,000 property limit. If you're buying in London or the South East, this cap may exclude your target homes. Putting money into a LISA and then finding you can't use it is frustrating.

If you're in a couple and both using LISAs, make sure both of you are first-time buyers. If one partner previously owned property, they can't use their LISA for the purchase, even if the other partner qualifies.

Track your overall ISA allowance. The £4,000 LISA limit is part of your total £20,000 ISA allowance, not in addition to it. Exceeding the allowance results in penalties from HMRC.

Should You Open a Lifetime ISA?

The Lifetime ISA works best if you're confident about one of two things: you'll buy a first home under £450,000 within a few years, or you won't need the money until 60. The 25% bonus is generous, but the 25% penalty for non-qualifying withdrawals turns that bonus into a trap.

If you're unsure whether you'll buy a house, a standard cash ISA or stocks and shares ISA gives you flexibility without penalties. You won't get the government bonus, but you won't lose money by changing your mind.

If you're certain about buying a first home and meet the criteria, the LISA is one of the best deals available. Free money on top of your savings, with no income limits or complex qualifying conditions beyond the age and property rules.

For retirement saving, compare the LISA with a workplace pension. Pensions often come with employer contributions, which can exceed the 25% LISA bonus. You also get tax relief on pension contributions at your marginal rate—20%, 40%, or 45%. However, pensions lock your money until at least age 55 (rising to 57 in 2028), whereas a LISA becomes accessible at 60. See Plain Pensions for detailed pension comparisons.

The Lifetime ISA suits disciplined savers with clear goals. If you fit the profile—young, saving for a first home or happy to lock funds until 60—it's a powerful tool. If you need flexibility or aren't sure about your plans, the penalty makes it risky.
