Can I have both a Cash ISA and a Lifetime ISA?

Yes. You can hold a Cash ISA and a LISA at the same time. Your LISA contributions (up to £4,000) count towards your overall £20,000 annual ISA allowance, so you can put the remaining £16,000 (or £8,000 from April 2027 if under 65) into a Cash ISA.

What is the LISA withdrawal penalty?

If you withdraw from a LISA for anything other than buying your first home (up to £450,000) or after turning 60, you'll face a 25% penalty on the total amount withdrawn. This means you lose not only the government bonus but also a portion of your own deposits — roughly 6.25% of what you put in.

Is a LISA better than a Cash ISA for first-time buyers?

For most first-time buyers, yes. The LISA's 25% government bonus (up to £1,000/year) gives you an instant return no Cash ISA can match. However, the property must cost £450,000 or less, you must be 18-39 to open one, and you must wait 12 months before using it for a purchase. A Cash ISA is still useful alongside a LISA for your emergency fund or savings above £4,000.

What happens to my LISA if I don't buy a house?

If you don't use your LISA for a first home, you can withdraw the full balance penalty-free from age 60. The money (including all government bonuses and any growth) comes out completely tax-free. If you need the money before 60 and aren't buying a first home, you'll face the 25% withdrawal penalty.

How much is the LISA government bonus?

The government adds 25% on top of whatever you deposit into your LISA, up to a maximum bonus of £1,000 per year (on £4,000 of deposits). The bonus is usually paid within 4-9 weeks of each deposit. If you contribute the maximum £4,000 every year from age 18 to 50, you'd receive £32,000 in bonuses.

Cash ISA vs Lifetime ISA (LISA): Which Is Right for You in 2025/26?

Two ISAs, Two Very Different Deals

A Cash ISA is the straightforward one: put money in, earn tax-free interest, take it out whenever you like. No strings attached.

A Lifetime ISA (LISA) is more generous but more restrictive. The government tops up your savings with a 25% bonus — up to £1,000 free money every year — but you can only use it for buying your first home or for retirement after age 60. Withdraw for any other reason and you'll lose more than just the bonus.

The good news? You don't have to pick just one. You can hold both a Cash ISA and a LISA at the same time. The question is how much to put into each. Full details on both products are available on GOV.UK's ISA page.

Side-by-Side: Cash ISA vs Lifetime ISA

Feature	Cash ISA	Lifetime ISA (LISA)
Annual contribution limit	£20,000 (dropping to £12,000 from April 2027 for under-65s)	£4,000
Government bonus	None	25% (up to £1,000/year)
Tax on interest/growth	Tax-free	Tax-free
Age to open	18+	18–39
Age to contribute	No upper limit	Until age 50
Access to funds	Any time, no penalty	25% penalty on non-qualifying withdrawals
Qualifying uses	Anything	First home (up to £450,000) or retirement (age 60+)
Counts towards ISA allowance?	Yes	Yes (part of £20,000 total)
Can hold both?	Yes — you can hold a Cash ISA and a LISA at the same time

Important: Your LISA contribution counts towards your overall £20,000 ISA allowance. So if you put £4,000 into a LISA, you can put up to £16,000 into a Cash ISA (or £8,000 from April 2027 if under 65). See full LISA rules on GOV.UK.

The 25% LISA Bonus: How It Works

The headline feature of the LISA is the government bonus. For every £1 you deposit (up to £4,000 per year), the government adds 25p. That's up to £1,000 per year in free money, paid directly into your LISA within 4–9 weeks of each deposit.

If you open a LISA at 18 and contribute £4,000 every year until you turn 50, you'll receive £32,000 in bonuses alone — on top of any interest or investment growth.

You deposit	Government adds	Total in LISA
£1,000	£250	£1,250
£2,000	£500	£2,500
£4,000 (max)	£1,000	£5,000

Note: The bonus is paid on deposits, not on interest earned. You earn interest or investment growth on top of the bonus — effectively earning returns on the government's money too.

The 25% Withdrawal Penalty: Why It's Worse Than It Sounds

If you withdraw from a LISA for anything other than buying your first home or after turning 60, you'll face a 25% penalty on the amount withdrawn. This isn't just clawing back the bonus — it actually takes some of your own money too.

Here's why: the 25% penalty is calculated on the total withdrawal (your money plus the bonus). Since the bonus was 25% of what you put in, the maths works out so that you lose more than just the bonus.

Step	Amount
You deposit	£1,000
Government bonus (25%)	+ £250
LISA balance	£1,250
Withdrawal penalty (25% of £1,250)	− £312.50
You receive	£937.50

That's a £62.50 net loss on your own money. You deposited £1,000 and only got £937.50 back. The penalty was temporarily reduced to 20% during COVID (meaning you'd only lose the bonus, not your own cash), but it's back to 25% now. Only withdraw early if you truly have no other option.

Using a LISA to Buy Your First Home

The LISA is one of the most generous savings tools for first-time buyers, but it comes with strict rules:

You must:

• Be a first-time buyer (never owned property before)
• Buy a property worth £450,000 or less
• Have had the LISA open for at least 12 months
• Use a conveyancer or solicitor to complete the purchase
• Intend to live in the property (not buy-to-let)

You cannot:

• Use it for a property over £450,000 (the penalty applies instead)
• Use it if you've previously owned a home, even abroad
• Use the funds before the 12-month waiting period is up
• Withdraw the money yourself — it goes directly to the conveyancer

The 12-month rule catches people out

You must have your LISA open for a full 12 months before you can use it for a property purchase. If you think you might buy in the next couple of years, open a LISA now — even with just £1 — to start the clock. The 12 months runs from the date you open the account, not from when you first deposit.

Using a LISA for Retirement

If you don't use your LISA for a first home, you can withdraw the full balance penalty-free from age 60. This makes the LISA a potential complement to your workplace pension, with one significant advantage: no income tax on withdrawals.

With a pension, you get tax relief on the way in but pay income tax when you withdraw (apart from the 25% tax-free lump sum). With a LISA, you get the 25% bonus on the way in and pay no tax on the way out. For basic-rate taxpayers, the effect is roughly equivalent. For higher-rate taxpayers expecting to be basic-rate in retirement, a pension usually wins because you get 40% relief going in and only pay 20% coming out.

Which Should You Choose? Common Scenarios

LISA winsSaving for your first home

If the property will be £450,000 or less and you're under 40, the LISA's 25% bonus is unbeatable. A £4,000 deposit becomes £5,000 before interest. No Cash ISA can match that return.

Cash ISA winsEmergency fund or short-term savings

If you need flexible access to your money, the Cash ISA is the clear choice. No penalties, no restrictions, no waiting periods. The LISA's 25% withdrawal penalty makes it unsuitable for an emergency fund.

LISA winsLong-term retirement savings (basic-rate taxpayer)

For basic-rate taxpayers, the LISA's 25% bonus is effectively equivalent to the 20% pension tax relief — but LISA withdrawals at 60 are completely tax-free, making it slightly better in practice. The £4,000 annual cap is the main limitation.

Cash ISA winsSaving more than £4,000 per year

The LISA caps contributions at £4,000/year. If you can save more, you'll need a Cash ISA (or stocks and shares ISA) for the rest. Max out the LISA first for the bonus, then put the remainder elsewhere.

Cash ISA winsYou're 40 or older

You can't open a new LISA after your 40th birthday. If you already have one, you can contribute until age 50, but if you've never opened one and you're 40+, the Cash ISA is your only option.

Use bothSaving for a house deposit + keeping an emergency fund

Put £4,000 into your LISA for the house deposit bonus, then put your emergency fund into a Cash ISA where you can access it freely. This is the optimal strategy for most first-time buyers.

How to Maximise Both: Allocation Strategy

Since your LISA allowance counts towards your overall £20,000 ISA limit, you need to think about how to split your savings. Here's a practical approach:

Max out the LISA first (£4,000)

If you qualify, always prioritise the LISA. The 25% bonus is an instant, guaranteed return you won't find anywhere else. That's £1,000 of free money.

Keep 3–6 months of expenses in a Cash ISA

Your emergency fund should be easily accessible. A Cash ISA gives you penalty-free withdrawals and tax-free interest — the best of both worlds for money you might need quickly.

Put remaining savings into a Cash ISA or S&S ISA

After LISA and emergency fund, use your remaining allowance for medium-term goals. From April 2027, under-65s will be limited to £12,000 in cash ISAs total, so consider stocks and shares ISAs for longer-term savings.

2027 planning: From April 2027, the Cash ISA limit for under-65s drops to £12,000. If you put £4,000 in a LISA, you'll only have £8,000 left for Cash ISAs. Read more about the upcoming changes in our Cash ISA Limit 2027 guide.
