Question to the HM Treasury:

To ask the Chancellor of the Exchequer, how many large business tax disputes have been submitted to international arbitration in the last 5 years.

Answered by Dan Tomlinson - Exchequer Secretary (HM Treasury)

The number of such disputes is fewer than five. HMRC are unable to disclosure the exact number as it could risk the identification of individual taxpayer(s).

Arbitration operates as a valuable mechanism under double taxation treaties, to ensure there is route to resolve double taxation where agreement cannot be reached between the relevant tax authorities, providing certainty and finality for taxpayers.

Often resolution can be reached outside of arbitration, which is why the number of arbitration cases are low. For context, for the latest year we have statistics, across 1 January 2023 to 31 December 2023, 348 cases were wholly dealt with under the procedure governing mutual agreement between tax authorities.

Question to the Foreign, Commonwealth & Development Office:

To ask the Secretary of State for Foreign, Commonwealth and Development Affairs, if she will take steps to include tackling international tax abuse in the Illicit Finance Summit.

Answered by Stephen Doughty - Minister of State (Foreign, Commonwealth and Development Office)

December's Illicit Finance Summit will focus on strengthening global enforcement against illicit finance, including by forging new partnerships on information sharing and asset recovery.

It will also agree new partnerships to tackle high-risk methods of moving dirty money, namely laundering in the property sector, misuse of crypto-assets, and trading in illicit gold.

By driving greater transparency, stronger enforcement and higher global standards, we will, alongside international partners, make it harder to hide or misuse money, including through tax evasion.
