Iceland’s tax authority reminds multinational groups of the obligation to notify which entity will file the Country-by-Country Report for the fiscal year 2025.
Iceland’s tax authority, the Revenue and Customs, has published a notification regarding the annual filing of the Country-by-Country (CbC) report on 25 November 2025.
Pursuant to Act no. 90/2003 on income tax, entities subject to Country-by-Country reporting obligations must, during 2026 and within one month of the end of the 2025 financial year (31 January 2026), notify the director of internal revenue of the group entity responsible for filing the Country-by-Country report, including the tax residence of that entity.
The notification must also clearly state whether the notifying entity is the multinational group’s ultimate parent entity or a surrogate parent entity.
All notifications must be submitted using Form RSK 4.31 and sent electronically to milliverdlagning@skatturinn.is. All inquiries relating to this obligation may be directed to the same email address.
Earlier, the Icelandic Directorate of Internal Revenue issued Notice No. 1676/2024, outlining the Country-by-Country (CbC) reporting requirements for multinational enterprises for the 2024 fiscal year.
