How to file the required information

All constituent entities are obliged to provide information for purposes of global minimum taxation by filing a new type of information return on top-up tax (GIR, GloBE Information Return) according to the OECD standard. The return must be filed within 15 months from the end of the accounting period. However, when filed for the first time, the return must be filed within 18 months. The return can be filed in a centralised manner, which means that the ultimate parent entity or a designated consolidated entity carries responsibility for the filing.

After filing, information is exchanged in automated information exchange between the tax authorities of the countries where the entities are located. In such a case, consolidated entities located in other countries must file a notification with the authorities of their country to state which entity is submitting a GIR on their behalf.

The data content of the return is based on the OECD standard, and the return will be filed electronically. The data content is defined in OECD publication GloBE Information Return. The OECD will release a schema to be followed when filing the return. The instructions will be updated as more information about the filing procedure is available.

Groups within the scope of regulation must submit their first information returns on top-up tax in accordance with the international standard by 30 June 2026. In addition, Finnish consolidated entities that must pay a top-up tax for their accounting periods under the regulation must file a top-up tax return in the same schedule. The returns will be filed electronically in Finland.

The Tax Administration will provide more information about filing when the global schema is released.
