Is a Lifetime ISA worth it?

For a first-time buyer who is sure they will buy a home costing £450,000 or less, a Lifetime ISA is hard to beat, because the 25% government bonus is free money you would not get in an ordinary savings account. It is worth far less, and can even cost you, if there is a real chance you will need the money for something else, because taking it out for any other reason before age 60 triggers a 25% withdrawal charge that can leave you with less than you paid in. The bonus is only worth having if you can keep to the rules.

What is the catch with a Lifetime ISA?

The catch is the 25% withdrawal charge. You can only take the money out without a charge to buy a qualifying first home, from age 60, or if you are terminally ill. Take it out for any other reason and a 25% charge applies to the whole amount, including the bonus. Because 25% of the larger, post-bonus pot is more than the 25% bonus you were given, you end up with less than your own deposits. The other limits are the £4,000 a year cap, the £450,000 property price ceiling, and that the account must be open at least 12 months before you buy.

How much can I put in a Lifetime ISA each year?

You can pay in up to £4,000 in each tax year, and the government adds a 25% bonus on top, so a maximum of £1,000 a year. That £4,000 counts as part of your overall £20,000 ISA allowance for the 2026/27 tax year, so paying the full £4,000 into a LISA leaves £16,000 of allowance for other ISAs. The bonus itself does not use up any of your allowance.

Who can open a Lifetime ISA?

You can open a Lifetime ISA if you are aged 18 to 39 and a UK resident. You must make your first payment before you turn 40. Once it is open you can keep paying in and earning the bonus until the day you turn 50, after which no more payments or bonuses are added but the account keeps any growth or interest. So the account can run for decades, but the window to open one is only between 18 and 39.

Can I lose money in a Lifetime ISA?

Yes, if you take the money out for the wrong reason. Suppose you pay in £4,000 and get the £1,000 bonus, giving £5,000. If you withdraw it early for something other than a first home or retirement, a 25% charge applies to the full £5,000, which is £1,250. You are left with £3,750, which is £250 less than the £4,000 you put in. The charge claws back more than the bonus because it is taken from the larger total. A cash LISA itself does not fall in value, but the withdrawal charge can.

Can I use a Lifetime ISA and a Help to Buy ISA together?

You can hold both, but you can only use the government bonus from one of them towards buying your first home, not both. Many people moved from a Help to Buy ISA to a Lifetime ISA because the LISA bonus is paid on a larger annual amount and can be used on higher-priced homes. Which works better depends on your own numbers, so check the current rules with your provider and on gov.uk before you decide.

Lifetime ISA explained: bonus, rules and the catch

A Lifetime ISA, or LISA, is a savings or investment account for your first home or for later life that pays a government bonus of 25% on what you pay in. You can save up to £4,000 a year and the government adds up to £1,000 on top. The trade-off is that the money is locked to two uses: a first home, or from age 60. Take it out for anything else before then and a 25% charge applies that can leave you with less than you paid in.

The short version

Pay in up to £4,000 a tax year and the government adds a 25% bonus, up to £1,000 a year.
That £4,000 counts inside your overall £20,000 ISA allowance, so it is not extra room on top.
You can open one between 18 and 39, and keep paying in until you turn 50.
You can take the money out with no charge only to buy a first home costing £450,000 or less, from age 60, or if you are terminally ill.
Any other withdrawal carries a 25% charge on the whole pot, which works out to less than you paid in. These are 2026/27 figures and general information, not financial advice.

The rules at a glance

The Lifetime ISA has a tight set of rules, and the bonus only pays off if you stay inside them. Here is the whole thing in one place, for the 2026/27 tax year.

Rule	What it means
Annual pay-in limit	Up to £4,000 each tax year
Government bonus	25% of what you pay in, up to £1,000 a year
ISA allowance	The £4,000 counts within your £20,000 overall ISA allowance
Who can open one	Aged 18 to 39, UK resident, first payment before you turn 40
Paying in	You can keep paying in and earning the bonus until you turn 50
First-home use	A first home costing £450,000 or less, account open at least 12 months
Later-life use	Withdraw with no charge from age 60
Other withdrawals	25% charge on the amount taken out, including the bonus

How the bonus works

The bonus is the reason to use a Lifetime ISA at all. For every £4 you pay in, the government adds £1, which is a 25% top-up. Pay in the full £4,000 in a tax year and you get the maximum £1,000 bonus, turning £4,000 into £5,000 before any interest or investment growth.

The bonus is paid monthly on what you have paid in, so it starts working from your first deposit rather than waiting until the end of the year. It does not use up any of your ISA allowance, so the £1,000 sits on top of the £4,000 you put in. A LISA can be a cash account, which pays interest like a normal savings account, or a stocks and shares account, where the money is invested and can rise or fall. Either way the 25% bonus is the same. To see how a pot like this could grow over several years with interest on top of the bonus, you can model it in the savings calculator.

A worked bonus example

Say you open a Lifetime ISA at 25 and pay in the full £4,000 every year for five years, ignoring interest to keep the sums clear. Here is what the bonus does:

Your money: £4,000 a year for five years is £20,000 of your own savings.
The bonus: 25% of each £4,000 is £1,000 a year, so £5,000 of government money over the five years.
The pot: £20,000 plus £5,000 is £25,000, before any interest.

That £5,000 is money you would not have in an ordinary savings account. Add interest on a cash LISA, or growth on a stocks and shares one, and the pot is larger again. The savings calculator lets you put in your own monthly amount and an interest rate to see the running total. If you are saving towards a property, it is worth pairing this with how much deposit you need for a mortgage so you know the target you are aiming the bonus at.

Using it for a first home

The most common reason people open a Lifetime ISA is to buy a first home, and this is where the bonus is taken out free of any charge. To use it this way the property has to cost £450,000 or less, it must be the first home you have owned, and you must be buying with a mortgage to live in the home yourself. The account also has to have been open for at least 12 months before you buy, counting from your first payment, so it pays to open one early even with a small deposit to start the clock.

The £450,000 ceiling is the figure to watch. It is the same across the UK and is not adjusted for higher-priced areas, so in parts of the country a first home can sit just above it and rule the LISA bonus out. If you buy with another first-time buyer who also has a LISA, you can each use your own bonus on the same purchase. Once you have a target price in mind, the deposit guide shows how the LISA pot fits alongside the rest of the money you need up front.

Who a LISA actually suits

A Lifetime ISA suits you well if you are a first-time buyer who is fairly sure you will buy a home within the £450,000 limit, because the 25% bonus is a guaranteed return no normal savings account can match. It also suits anyone happy to lock money away for retirement and leave it untouched until 60, where the bonus again works in your favour over a long stretch.

It suits you less, and can work against you, if there is a real chance you will need the money for anything else first. An emergency fund does not belong in a LISA, because reaching it early costs you the charge below. Self-employed people sometimes weigh a LISA against a pension for retirement, and a pension often wins on tax for higher earners, so a LISA is not automatically the right retirement home for your money. The honest answer is that the LISA rewards certainty: the more sure you are about which of the two permitted uses you will pick, the more the bonus is worth having.

The withdrawal-charge trap

This is the part that catches people out, so it is worth being precise. You can take money out of a Lifetime ISA with no charge only in three cases: to buy a qualifying first home, from age 60, or if you are terminally ill with less than 12 months to live. Any other withdrawal carries a 25% government charge on the amount you take out, and that charge is applied to the whole pot, including the bonus.

Because the charge is 25% of the larger, post-bonus amount, it takes back more than the bonus gave you. Take the example gov.uk uses: pay in £800 and the 25% bonus adds £200, giving a £1,000 pot. Withdraw it early for the wrong reason and the 25% charge is £250, leaving you with £750. You put in £800 of your own money and got back £750, a £50 loss, even though nothing went wrong with the savings themselves. Scale that up and a £4,000 contribution plus its £1,000 bonus becomes £5,000, a 25% charge of £1,250, and £3,750 back, which is £250 less than the £4,000 you saved.

That is the single most important thing to understand before you open one. The bonus is genuinely generous, but it comes with strings, and the charge is designed so that breaking the rules claws back the government bonus and takes a bite out of your own money too. If there is a serious chance you will need the cash for something other than a first home or retirement, an ordinary savings account or cash ISA may leave you better off even without a bonus.
