MTT52100 | Administration: The information return: Structure and format
From HM Revenue & Customs · Multinational Top-up Tax and Domestic Top-up Tax
The information return will contain the same information as the GloBE Information Return (GIR) developed by the OECD, which includes:
identification of the members of the group
information on the corporate structure of the group
information relevant to the determination of effective tax rates, top-up amounts, and allocation of top-up amounts
The GIR contains a general section (Section 1) and jurisdictional sections (Sections 2 and 3). Notably, where no jurisdiction has taxing rights over a particular jurisdiction, columns 1.4.2 to 1.4.9 of table 1.4 in Section 1 and the jurisdictional sections in Sections 2 and 3 do not need to be completed in respect of that particular jurisdiction.
Information returns must be submitted using third party software and must conform to the XML Schema format designed by the OECD.
More details on the GIR and XML Schema can be found on the OECD’s website here: Global Anti-Base Erosion Model Rules (Pillar Two) | OECD
