Individual Savings Accounts
The question
To ask the Chancellor of the Exchequer, with reference to page 79 of the HM Budget 2025 Policy Costings, published in November 2025, for what reason the Exchequer Impact of the Cash ISA changes fluctuate from (a) £5 million in 2028-29 to (b) £35 million in 2029-30 to (c) £15 million in 2030-31.
Answered by Lucy Rigby
The figures set out on page 79 of the Budget 2025 Policy Costings document reflect the estimated Exchequer impact from a combination of savings tax changes.
The savings measures covered are:
- Making the Help to Save scheme permanent from April 2027,
- Maintaining the total ISA annual subscription limit at £20,000 with cash limit reduced to £12,000 for under-65s from April 2027,
- Delaying the ISA digitalisation until April 2028, and
- Maintaining the ISA subscription limits until 2030/31.
The profile of the Exchequer impacts reflects the different commencement dates of these changes, as well as the timing of receipts collected through Self-Assessment.
