Overview
The Switzerland Pillar Two Self Assessment Return Form is a jurisdiction specific self declaration tax return that multinational groups use to report and settle their top-up tax obligations as part of Pillar Two compliance in Switzerland. Filed electronically through the OMTax platform by the designated lead entity the form captures the total top-up tax liability of the group in line with Switzerland's domestic legislative requirements. This template is built to work seamlessly within both Switzerland's own Pillar Two rules and the broader OECD Global Minimum Tax (GloBE) framework giving compliance teams a dependable and structured starting point for every filing cycle.

FAQs
Why do companies need to file the Switzerland Pillar Two Self Assessment Return Form?
The form is how multinational groups formally declare and settle their top-up tax liabilities in Switzerland. It sits separately from the GloBE Information Return and is where the actual payment obligation is triggered. All registered groups must file it regardless of whether any top-up tax is due.
Does qualifying for a safe harbour remove the need to file the Switzerland Pillar Two Self Assessment Return Form?
No. Safe harbour relief simplifies the calculations but does not remove the filing obligation. The return must still be submitted for every accounting period the group is within scope of Switzerland's Pillar Two rules.
How does the Switzerland Pillar Two Self Assessment Return Form interact with the GloBE Information Return?
The two filings serve different purposes and both are required. The GloBE Information Return contains the detailed GloBE calculations while the Self Assessment Return focuses on declaring the total top-up tax liability in Switzerland. Neither replaces the other.
What happens if a group's top-up tax liability changes after the Switzerland Pillar Two Self Assessment Return Form has been submitted?
Switzerland allows groups to submit a replacement return where figures need to be corrected after the original submission. Identifying adjustments early is important to ensure amended returns are filed within the permitted window and any additional tax is settled without penalties.
