HM Revenue and Customs (HMRC) has revealed plans for a new “digital reporting” system aimed at identifying taxpayers exceeding their Individual Savings Account (ISA) limits. Senior officials briefed Members of Parliament (MPs) about these developments ahead of rule changes set to take effect from next year.
The tax authority confirmed it will shortly publish regulations to implement a significant adjustment to the ISA allowance framework. Following the Autumn Budget 2025 announcement by the Labour government, from April 2027, the annual ISA allowance for millions of savers will be reduced. Currently, individuals can deposit up to £20,000 each tax year across any combination of cash and investment ISAs.
However, under the new rules, the total allowance remains effectively the same, but a maximum of £12,000 can be used flexibly between cash and investment accounts. The remaining £8,000 will be restricted for investment purposes only, with no option for deposit into cash ISAs. Notably, those aged 65 and above will be exempt from this modification and retain the existing allowance.

Given the added complexity this change introduces, the Treasury Committee queried how HMRC plans to ensure savers comply with the updated limits. Jonathan Athow, Director General of Strategy and Policy at HMRC, explained that a new digital reporting requirement is being introduced. “Historically, the ISA system was paper-based, or at least started that way, and we are now digitising the process,” he said.
Athow detailed the rationale behind this move: “No single ISA manager can fully monitor each saver’s total activity across providers. Our digital service will provide a clearer overview, helping to identify where limits may be exceeded and enabling us to take appropriate action.”
When asked about the frequency of data updates, he stated, “There will be a delay, though details are still being finalised. We anticipate receiving data quarterly, which is more frequent than the previous annual submissions. This will facilitate in-year interventions, but I would need to verify the exact timings.”
MPs also inquired about HMRC’s response to cases where individuals exceed their ISA limits. Athow responded, “We expect ISA managers to rectify any such instances. Providers should withdraw excess funds to ensure compliance with limits. However, tax charges will apply if limits are breached.”
This digital reporting initiative represents a significant shift towards modernising ISA regulation and ensuring adherence to new rules designed to balance investment flexibility with fiscal oversight.
