£20,000 vs £4,000: The Allowance Gap Is Enormous
The ISA annual allowance is £20,000. The LISA allows just £4,000 of that. See <a href="/posts/isa-guide-lifetime-isa-lisa-uk-202526-how-the-25-government-bonus-works-and-whether-its-right-for-you">Lifetime ISA guide</a> for more details. Even LISA advocates concede you need a stocks & shares ISA alongside it — which immediately raises the question: why not simplify?
One account. One provider. One fee structure. £20,000 of headroom instead of £4,000. No bonus calculations, no withdrawal penalties, no property cap anxieties.
The LISA's £1,000 annual bonus looks generous in isolation. But it caps your tax-free investment space at a fifth of what's available. A 30-year-old putting £20,000 into a stocks & shares ISA at 7% annual returns accumulates roughly £39,400 after five years. The same person splitting £4,000 to a LISA and £16,000 to a S&S ISA ends up with the same total market exposure but pays two sets of platform fees, manages two accounts, and faces withdrawal restrictions on 20% of their money.
For savers who can fill most of their ISA allowance — and our higher-rate taxpayer ISA strategy shows how many can —, the LISA's bonus is a consolation prize for accepting a worse wrapper.
