Tax measures to encourage economic growth

HM Treasury and HMRC identify which non-structural reliefs have economic objectives and how these could be grouped together to provide oversight on how reliefs with similar objectives are working together to deliver government objectives, for example those aimed at business investment. This should include assessing the extent to which reliefs are achieving their objectives and whether the economic gains justify the scale of relief.

HM Treasury and HMRC should make a clear articulation of resources required to effectively administer and evaluate tax reliefs in tax information and impact notes. HMRC needs to ensure that teams can access the subject matter expertise needed for complex or technical tax reliefs

HM Treasury and HMRC should ensure the annual budget for evaluating tax reliefs is commensurate with the number and complexity of reliefs that need evaluating each year. The departments should ensure evaluations are completed in a timely way and commit to publishing evaluations within three months of completion, subject to ministerial approval.

HMRC should design proportionate controls and plan interventions at the beginning of a relief?s lifecycle based on risk assessment and learnings from other reliefs to: ? establish appropriate up-front checks on generous reliefs; ? set out plans for evaluations to be carried out as soon as practicable and publish the timetable; ? plan for timely review of monitoring information to get interim evidence; and ? ensure speed of response where reliefs are identified as not meeting desired objectives or do not function as planned.

Ref Page 14, 23e · Implemented Q1 2026-27

HMRC should improve the transparency of relief costs by committing to provide comparisons of forecast and outturn costs compiled on the same basis. This should also inform internal reporting and analysis: ? HMRC should report where tax reliefs greatly exceed the initial expected costs; and ? HMRC should investigate differences, using robust evidence to form conclusions

Ref Page 15, 23g · Implemented Q1 2027-28

Where the costs of tax reliefs rise rapidly, and beyond an economically credible scenario, HMRC should, where proportionate, investigate a sample of claims to check whether there is widespread non-compliance. It should put in place a rapid response capability where widespread non-compliance occurs
