Collection

Multinational Top-up Tax and Domestic Top-up Tax

This collection is for anyone who needs to refer to publications about these taxes, including policy papers, consultations, and direct mailing to HMRC customers.

In October 2021, more than 135 countries, including the UK, reached an agreement known as Pillar 2 to ensure that the largest corporate groups will be subject to a minimum rate of tax by enacting a global minimum corporate tax rate of 15%.

As part of that agreement, the government has introduced 2 new taxes in the UK: the Multinational Top-up Tax (MTT) and Domestic Top-up Tax (DTT). These taxes apply to accounting periods beginning on or after 31 December 2023.

A new IT system is being developed to administer the new taxes. Companies are now able to register for the taxes.
