Lifetime ISA Explained | Why a Lifetime ISA Can Support Your First Home Purchase. A Lifetime ISA is a government-backed savings account designed to help first-time buyers save for a home. It allows eligible savers to receive a government bonus on their contributions, helping to build a mortgage deposit faster.
For many buyers, a Lifetime ISA forms part of a wider first-time buyer mortgage strategy, especially when combined with professional mortgage advice.
What Is a Lifetime ISA
A Lifetime ISA allows you to save up to £4,000 per tax year. The government adds a 25 per cent bonus, up to £1,000 annually. The account can be used to buy your first home or save for later life.
Funds must be used in line with scheme rules. If withdrawn early for non-qualifying reasons, a charge may apply.
How a Lifetime ISA Helps With a Mortgage Deposit
A Lifetime ISA can be used as part of your deposit when applying for a first-time buyer mortgage. Mortgage lenders typically accept Lifetime ISA funds, provided the purchase meets the scheme’s criteria.
You can learn more about deposit requirements on our First Time Buyer Mortgage page.
Saving through a Lifetime ISA can also complement other options such as gifted deposits or Help to Buy alternatives.
Who Can Benefit From a Lifetime ISA
A Lifetime ISA may be suitable if you:
- Are aged between 18 and 39
- Are saving for your first home
- Plan to buy within price limits set by the scheme
- Want to boost savings with a government bonus
Before applying for a mortgage, it is important to understand how savings products and lending criteria work together. Our Mortgage Advice service helps buyers understand this clearly.
Lifetime ISA Key Features Explained
A Lifetime ISA is designed to help eligible savers build funds for a first home or later life. Understanding how it works is important before using it as part of a wider first-time buyer mortgage plan.
Eligibility Criteria
To open a Lifetime ISA, you must be:
- A UK resident
- Aged between 18 and 39 at the time of opening the account
Once opened, you can continue contributing until age 50.
Contribution Limits
You can save up to £4,000 per tax year into a Lifetime ISA. Contributions can be made as a lump sum or through regular payments.
The Lifetime ISA allowance forms part of your overall annual ISA allowance, which is £20,000 for the 2025 to 2026 tax year.
Government Bonus
The government adds a 25 per cent bonus to your Lifetime ISA contributions. This provides up to £1,000 in additional savings per tax year.
Bonuses are usually paid monthly or annually, depending on the provider. This bonus can significantly increase a mortgage deposit when buying a first home.
Tax Free Growth
All interest earned or investment growth within a Lifetime ISA is free from UK income tax and capital gains tax. This makes it a tax-efficient way to save when compared with standard savings accounts.
Types of Lifetime ISA
There are two main Lifetime ISA options:
- Cash Lifetime ISA, which offers lower risk and is often suited to those planning to buy a home within a few years
- Stocks and Shares Lifetime ISA, which may offer higher long-term growth but carries investment risk and may fall in value
Choosing the right type depends on your timeframe and risk tolerance. This should be considered carefully before applying for a residential mortgage.
When You Can Access Funds Without a Penalty
You can withdraw money from a Lifetime ISA without paying the government charge if the funds are used for:
- Buying your first home, provided the property price is £450,000 or less, and the account has been open for at least 12 months
- Accessing funds after the age of 60
- Terminal illness where life expectancy is less than 12 months
When purchasing a property, Lifetime ISA funds are commonly used alongside afirst-time buyer mortgage, subject to lender criteria.
Withdrawal Charges
If money is withdrawn for any other reason, a 25 per cent government charge applies to the full amount withdrawn. This means you could receive less than you originally paid in. Understanding these rules is important before using a Lifetime ISA as part of your home-buying plans.
Key Benefits of a Lifetime ISA
| Key Benefit | Explanation |
|---|---|
| Boosting Your Savings Faster | The 25 per cent government bonus provides a guaranteed boost to your savings. This can make a meaningful difference when building a mortgage deposit, particularly for first-time buyers. |
| Flexible Long-Term Purpose | A Lifetime ISA can support two major financial goals: buying your first home and saving for later life after age 60. This flexibility allows savers to adapt their plans as circumstances change. |
| Tax-Efficient Growth | All savings growth within a Lifetime ISA remains tax-free. This helps your funds grow more efficiently than in many taxable savings or investment accounts. |
| Benefits for Couples Buying Together | If both partners qualify as first-time buyers, each can open a separate Lifetime ISA. When combined, this can significantly increase the total deposit available for a joint first-time buyer mortgage. |
| Portability Between Providers | Lifetime ISAs can be transferred between providers. This allows savers to seek better interest rates or investment options while keeping the tax advantages and government bonus intact. |
| Inheritance Considerations | Lifetime ISA funds form part of your estate for inheritance tax purposes. However, beneficiaries can access the funds without paying the Lifetime ISA withdrawal charge. |
