Conclusion (the committee's words)
We asked HMRC when it expects to see the benefits of the extra investment in its IT. HMRC told us that by the end of the Spending Review period it wants to be a digital first organisation, with 90% of customer interactions going through digital channels. It also expects to bring up its security maturity level to meet best practice standards. In the large business directorate, HMRC said it wants to modernise its approach to data risking and case management and automate a large amount of work it carries out. HMRC also told us that it will be increasing its use of AI in the large business directorate, and expects to have access to a suite of new AI tools in either late 2026 or early 2027.29
