What's Actually Changing
The Lifetime ISA launched in 2017 with a dual purpose: help under-40s buy a first home or save for retirement after age 60. The new First-Time Buyer ISA keeps the first purpose and kills the second.
Here's what the transition looks like:
- 2026–2027: Existing LISAs continue as normal. You can still contribute up to £4,000 per year and receive the 25% bonus.
- 2027 Migration Window: Transfer your LISA balance to the new FTB ISA penalty-free. This is your one clean exit.
- April 2028: LISAs close permanently. The FTB ISA launches with a crucial difference — the bonus is only paid at the point of property purchase, not on each annual contribution.
The 25% withdrawal penalty on non-qualifying withdrawals remains brutal. Take money out of a LISA for anything other than a first home or after age 60, and you lose 25% of the total withdrawal. That's not 25% of your gains — it's 25% of everything, which means you actually lose 6.25% of your own contributions.
For self-employed savers using the LISA as a retirement vehicle, the penalty-free migration window in 2027 is the critical date. Miss it, and you face that 25% charge to access your own money.
