How this is worked out

The total ISA allowance for the 2025/26 tax year is £20,000. It applies across all adult ISAs you hold — the £20,000 is shared, not per account.

The Lifetime ISA has its own annual cap of £4,000 within that £20,000, and HMRC pays a 25% bonus on contributions up to that cap.

Junior ISAs are separate (£9,000/year for under-18s) and aren’t counted here.
