UN Tax Convention

International collaboration helps to address global tax challenges. This is why the Government is actively involved in the initiatives led by the Organisation for Economic Co-operation and Development (OECD) and the United Nations (UN) on tax policy.

The Government is committed to ensuring international tax rules and standards are effective as well as inclusive. To achieve this, the Government has supported consensus-based reform through the OECD, including through the G20/OEDC Framework (with over 130 members) and the Inclusive and the Global Forum (with over 160 members). Non-OECD members also participate in equal footing, reflecting the OECD’s increasingly inclusivity efforts in recent years.

In the UK, we are proud to report that the estimated tax gap for the 2021/22 tax year has reached an all-time low of 4.8%, a substantial improvement from 7.5% in 2005/06. The Government is also investing an additional £47.2 million to enhance the capabilities of HM Revenue and Customs in tax debt collection, with a focus on supporting individuals who are temporarily unable to pay.
