No investment return is assumed anywhere on this page. Every figure is money you paid in plus the government bonus — the only part that is guaranteed. A stocks-and-shares LISA can do better or worse than this, and nobody can tell you which.

What it costs your ISA allowance

£4,000 of the £20,000 allowance, leaving £16,000 for every other ISA put together. Announced at Autumn Budget 2025: from 6 April 2027 the cash ISA allowance falls to £12,000 for savers under 65, while the overall £20,000 ISA allowance is unchanged — the balance must go into stocks and shares or innovative finance ISAs. See the 2027 change.

Questions

How much bonus do I get on £4,000 a year?

£1,000. The bonus is 25% of what you pay in, up to £4,000 a year, so the most anyone can earn is £1,000 a year.

When does the bonus actually arrive?

Your provider claims it monthly on what you paid in that month, and HMRC pays it into the account afterwards — commonly four to nine weeks later. The tables above show it in the year you earned it, not the day it lands.

Does £4,000 use up my ISA allowance?

Yes. LISA payments count toward the same £20,000 ISA allowance as every other ISA, so £4,000 into a LISA leaves £16,000 for cash, stocks-and-shares and innovative finance ISAs combined. The bonus itself does not use any allowance.

What if I want the money for something else?

Taking it out before 60 for anything other than a first home costs 25% of the withdrawal, which is 6.25% of your own money — more than the bonus was worth. There is a page for that: what an early withdrawal costs.
