Description
Closing the tax gap is a key strategic priority for HMRC. In the 2023 to 2024 tax year, the tax gap is estimated to be 5.3% of total theoretical tax liabilities, or £46.8 billion in absolute terms. This is driven by a range of customer behaviours from simple error to deliberate evasion. Identifying deliberate evasion is inherently difficult across a very large population of customers. By its nature the intent of deliberate evasion is to hide and deceive. This can lead to risk targeting and response being more costly for HMRC which impacts on our ability to close the tax gap and increases burdens on compliant customers. Being able to identify deliberate evasion accurately at population level will improve HMRC's approach to managing the tax gap and reduce the impact on compliant customers.
HMRC will run a competition to explore ways to address this challenge.
