Lifetime ISA Rules 2026: Using a LISA to Buy Your First Home or Fund Retirement

What Is a Lifetime ISA?

A Lifetime ISA (LISA) is a tax-advantaged savings account designed for two purposes: buying your first home and saving for retirement. It was launched in April 2017 and is available to UK residents aged 18 to 39.

The key feature of a LISA is the government bonus. For every GBP 4 you save, the government adds GBP 1 -- a 25% top-up, paid monthly into your account. On the maximum contribution of GBP 4,000 per year, that is a bonus of up to GBP 1,000 per year.

Eligibility and Contribution Limits

To open a LISA, you must be:

• A UK resident
• Aged 18 or over
• Under 40 at the time you open the account

Once open, you can contribute up to GBP 4,000 per tax year. Contributions count towards your overall annual ISA allowance (GBP 20,000 in 2026/27), so using GBP 4,000 in a LISA leaves GBP 16,000 for other ISA types in the same year.

You can keep contributing until you reach age 50. After that, your LISA remains open and continues to earn returns, but no new contributions or government bonuses are paid.

Using a LISA to Buy Your First Home

You can use your LISA savings (including the bonus) as a deposit on your first home if:

• You are a first-time buyer (you have never owned a home anywhere in the world)
• The property costs GBP 450,000 or less
• You are purchasing with a mortgage (cash purchases are not eligible)
• Your LISA has been open for at least 12 months

The funds are sent directly to your conveyancer as part of the completion process. You do not withdraw the money yourself.

If you are buying with a partner who also has a LISA, both of you can use your individual LISAs towards the same property, as long as you both qualify as first-time buyers.

Using a LISA for Retirement

From age 60, you can withdraw all funds from your LISA completely free of tax and without any penalty. The entire pot -- your own contributions plus the government bonus plus any investment growth -- is yours to keep.

This makes a LISA a useful supplement to a pension, particularly for those who want flexibility. Unlike a pension, a LISA does not offer income tax relief on contributions, but it also has no rules about how you spend the withdrawn funds.

The Withdrawal Penalty

Withdrawing from a LISA for any reason other than buying a first home, reaching age 60, or terminal illness triggers a 25% penalty. This is applied to the total withdrawal amount (your own money plus the bonus), so it effectively claws back the entire government bonus and also charges you approximately 6.25% of your original contributions.

For example: you contribute GBP 10,000, the bonus adds GBP 2,500, giving a total of GBP 12,500. A 25% penalty on GBP 12,500 is GBP 3,125, leaving you with GBP 9,375 -- less than you put in.

The LISA is therefore best treated as locked-in unless you meet a qualifying condition.
