Welcome to this guidance video. In this video, we will examine the filing and payment for Global minimum tax.
All filings must be made by the later of 15 months after the last day of the fiscal year or 30th June 2026. However, in the transition year, which means the first fiscal year that the MNE group comes within the scope of the GloBE Rules, the due date is the later of 18 months after the last day of the fiscal year or 30th June 2026.
All local constituent entities of an MNE Group in scope of the Global Minimum Tax should file a GloBE Information Return by the filing deadline. However, in certain cases, the filing obligation for the GloBE Information Return may be waived, which will be explained shortly.
Any local constituent entities with an obligation to pay an allocable share of top-up tax should file a Top-up Tax Return by the filing deadline.
For the 2024 fiscal year, the following four return forms apply.
Form No. 53 and 54 are the GloBE Information Return.
Form No. 55 is the Foreign Constituent Entity Information Return.
Form No. 56 is the Top-Up Tax Return, which is related to the Income Inclusion Rule.
This is the most important part regarding the filing obligation for the Global Minimum Tax.
As explained earlier, all local constituent entities located in Korea must file the GloBE Information Return.
However, the filing obligation may be waived if another local constituent entity files the GloBE Information Return.
Alternatively, the filing obligation may also be waived where a foreign constituent entity in the same MNE group files GloBE Information Return in a jurisdiction in which the GIR MCAA, is activated.
However, in this case, the local constituent entity should file Foreign Constituent Entity Information Return to KOREA NTS before the due date.
Returns related to the Global Minimum Tax may be filed electronically through Hometax or submitted in paper form by mail or in person at the tax office. However, the GloBE Information Return may only be filed electronically.
To file electronically through Hometax, first log in. After logging in to Hometax, to file a GloBE Information Return or the Foreign Constituent Entity Information Return, click [Certificates·Registration·Application] and then click [Global Minimum Tax Applications·Filings]
Select [GloBE Information Return Filing] or [Foreign Constituent Entity Information Return Filing], depending on the return to be filed.
To file the Top-Up Tax Return, click [Tax Filing] and [Global Minimum Tax Filing]. Select [Top-Up Tax Return(Income Inclusion rule)]
Payment of the allocable share of top-up tax may be made through Hometax, financial institutions, the Korea Financial Telecommunications and Clearings Institute, or unmanned payment kiosks at tax offices.
An administrative fine of 100 million Korean won may be imposed if a GloBE information return or a Foreign Constituent Entity Information Return is not filed by the due date or if false data is submitted.
In addition, an administrative fine of up to 200 million Korean won may be imposed for failure to comply with requests to submit the return or to make corrections.
However, for transition period, the administrative fine may be waived if the requirements under Article 144 (3) of Enforcement Decree of the Adjustment of International Taxes Act are met.
The allocable share of top-up tax is also subject to additional tax, as with other taxes.
However, during the transition period, additional tax for non-filing or underreporting is waived, and additional tax for delayed payment is reduced by 50%.
This concludes the filing and payment for Global Minimum Tax. Thank you for watching.
