Top-up tax: temporal application and exercise of elections of the administrative guidance of 5 January 2026 on the Side-by-Side Package
On 5 January 2026, the Inclusive Framework on BEPS1 of the OECD2 and the G20 (Inclusive Framework) adopted the administrative guidance that includes the Side-by-Side Package3. The Side-by-Side Package includes five safe harbour rules.
Article 2 paragraph 3 of the Ordinance of 22 December 2023 on the Minimum Taxation of Large Corporate Groups (Minimum Taxation Ordinance, OMinT; SR 642.161) provides that the Global Anti-Base Erosion Model Rules of the Inclusive Framework (Global Anti-Base Erosion Model Rules, GloBE Rules)4 are to be interpreted, in particular, in accordance with the associated commentaries5 and related regulations of the Inclusive Framework. The safe harbour rules are part of the consolidated commentary and the GloBE Rules (see Art. 8.2 of the GloBE Rules). The safe harbor rules adopted to date by the Inclusive Framework are therefore applicable in Switzerland pursuant to Article 2 paragraph 3 of the OMinT.
The following safe harbour rules of the Side-by-Side Package are directly applicable as of the following dates:
- Extension of the Transitional CbCR Safe Harbour: Provided that the relevant conditions are met (in particular regarding the “once out, always out” principle), this safe harbour rule may now also be applied to fiscal years beginning no later than 31 December 2027 and ending no later than 30 June 2029.
- Substance-based Tax Incentive Safe Harbour: Provided that the relevant conditions are met, this safe harbour rule may be applied to fiscal years beginning on or after 1 January 2026.
- Side-by-Side Safe Harbour: Provided that the relevant conditions are met, this safe harbour rule may be applied at the earliest to fiscal years beginning on or after 1 January 2026. In this context, the date specified in the so-called Central Record is relevant.
- UPE Safe Harbour: Provided that the relevant conditions are met, this safe harbour rule may be applied to fiscal years beginning on or after 1 January 2026.
- Simplified ETR Safe Harbour: Provided that the relevant conditions are met, this safe harbour rule may be applied to fiscal years beginning on or after 31 December 2025. Article 9 paragraphs 2 and 3 of the OMinT also apply to the calculations under the Simplified ETR Safe Harbour.

In particular, the GloBE Rules are to be interpreted in accordance with the associated commentaries4 and related regulations of the Inclusive Framework on BEPS of the OECD and the G20 (see Art. 2 para. 3 of the OMinT).
The administrative guidance on Article 9.1 of the GloBE Rules adopted on 13 January 2025 by the Inclusive Framework on BEPS of the OECD and the G20 (hereinafter referred to as “the administrative guidance”)5 is part of the consolidated commentary. The administrative guidance governs how the transitional rules of Article 9.1 of the GloBE Rules are to be applied in relation to deferred tax assets (DTAs) arising from certain tax benefits, elections, choices or a newly introduced corporate income tax after 30 November 2021. It further stipulates that the deferred tax expense arising from the reversal of such DTAs shall be excluded from the calculation of the effective tax rate (ETR). However, a time-limited (Grace Period) and amount-limited (Grace Period Limitation) exception is permitted. The list of cases which the administrative guidance describes in paragraph 8.5 of the consolidated commentary to Article 9.1.2 of the GloBE Rules is not exhaustive.
The Federal Chambers adopted two motions of identical wording on 15 December (National Council, motion 25.4392) and 18 December 2025 (Council of States, motion 25.4399), respectively, thereby instructing the Federal Council to amend the OMinT in such a way that the provisions of the administrative guidance apply in Switzerland only to tax benefits granted as from 1 January 2025.
The amendment to the OMinT requested by Parliament can, in most cases, not be implemented before the expiry of the filing deadline of the top-up tax returns. It is therefore necessary to establish how the declaration for top-up tax returns whose filing deadline expires before the completion of the process to implement the adopted motions is to be made.
Pursuant to applicable law and until the Federal Council decides on a possible amendment to the OMinT, the administrative guidance must be applied. Constituent entities subject to top-up tax must complete the relevant top-up tax returns in accordance with the administrative guidance and the Grace Period Limitation set out therein, and file them within the deadline set by the OMinT. An extension of the filing deadline is not possible under applicable law. It is essential that the constituent entity subject to top-up tax indicates, in the remarks on the relevant tax return, that its effective tax rate has been reduced as a result of the cap imposed by the Grace Period Limitation. The cantonal tax authorities will not issue final tax assessments for the cases concerned until the Federal Council has made its decision.

The administrative guidance of the Inclusive Framework on BEPS of the OECD1 and the G20 countries, published on 18 December 2023 (hereinafter referred to as “the administrative guidance of December 2023”)2, deals with hybrid arbitrage arrangements within the transitional CbCR safe harbour in Chapter 2.6. It provides that the document on safe harbours, published on 20 December 20223, is to be supplemented by paragraphs 74.25 to 74.31 of the administrative guidance of December 2023.
Paragraph 74.31 of the administrative guidance of December 2023 allows jurisdictions that, based on constitutional grounds or other superior law, are unable to apply paragraphs 74.25 to 74.30 of the administrative guidance of December 2023 to transactions entered into after 15 December 2022, to apply them only to transactions entered into after 18 December 2023.
It is therefore necessary to determine the date of application of these rules for the Swiss jurisdiction:
Chapter 2.6 concerning hybrid arbitrage arrangements within the transitional CbCR safe harbour of the administrative guidance dated 18 December 2023 applies to transactions entered into after 18 December 2023.

1. Background
The top-up tax (supplementary tax) is calculated based on the provisions of the Global Anti-Base Erosion Model Rules of the Inclusive Framework on BEPS of the OECD1 and the G20 countries (Global Anti-Base Erosion Model Rules, GloBE Rules2; see Art. 9 and Art. 11 of the Ordinance of 22 December 2023 on the Minimum Taxation of Large Corporate Groups [Minimum Taxation Ordinance, OMinT; SR 642.161]). In accordance with Article 2 paragraph 1 of the OMinT, the GloBE Rules apply by analogy to Swiss top-up tax. In particular, the GloBE Rules are to be interpreted in accordance with the associated Commentary3 and related regulations of the OECD and the G20 countries (see Art. 2 para. 3 of the OMinT).
When calculating the effective tax rate for the top-up tax, covered taxes are an important element (see Chapters 4 and 5 of the GloBE Rules). Covered taxes may also include the non-recoverable Swiss withholding tax (residual tax; see Art. 4.2. of the GloBE Rules).
In principle, covered taxes must be allocated to the constituent entity in which they are recorded (see Art. 4.1.1. of the GloBE Rules). However, Article 4.3. of the GloBE Rules provides for various provisions for the reallocation of covered taxes between different constituent entities.
Article 4.3.2. letter e of the GloBE Rules concerns the allocation or reallocation of taxes on distributions. Consequently, the covered taxes accrued in the financial accounts of a constituent entity’s direct constituent entity-owners, that are incurred on distributions from the constituent entity during the fiscal year, are allocated to the distributing constituent entity.
2. Exclusion of certain provisions of the GloBE Rules for Swiss top-up tax
In accordance with Article 2 paragraph 2 letter b of the OMinT, Article 4.3.2. letter e of the GloBE Rules in particular is not applicable to Swiss top-up tax.
The aim of this exclusion is to ensure that the covered taxes of a constituent entity-owner on distributions from qualifying participations that are allocable to the locally resident distributing constituent entity are not taken into account when calculating Swiss top-up tax, in line with the consolidated commentary on the term ‘Qualified Domestic Minimum Top-up Tax’ (‘QDMTT’).
The purpose of this special rule for the qualified domestic minimum top-up tax is to give a jurisdiction the primary right to tax locally resident constituent entities. The rule also aims to avoid complex international allocation rules for foreign taxes in the case of the qualified domestic minimum top-up tax.
However, the consolidated commentary stipulates4 that in the case of withholding taxes imposed by the country of the distributing constituent entity on the distributions, these may still be taken into account by the locally resident distributing constituent entity for the qualified domestic minimum top-up tax.
3. Consideration of the residual tax on distributions from Swiss constituent entities for Swiss top-up tax (outbound issues)
It follows from the explanations under section 2 above that the residual tax on distributions of a Swiss constituent entity must be recognised as covered tax for the calculation of Swiss top-up tax at the level of the distributing Swiss constituent entity.
4. Consideration of the residual tax on distributions from foreign constituent entities for Swiss top-up tax (inbound issues)
Under Article 3.2.1. letter b of the GloBE Rules, dividends and other distributions are to be excluded from GloBE income or loss if they qualify as so-called excluded dividends. Article 4.1.3. letter a of the GloBE Rules also excludes the tax expense with respect to income excluded under Chapter 3 from the adjusted covered taxes of the receiving constituent entity. The non-recoverable foreign withholding taxes on such distributions are therefore not to be taken into account when calculating Swiss top-up tax; these are to be allocated to the distributing foreign constituent entity.

4 See consolidated commentary on Article 10.1 of the GloBE Rules, Qualified Domestic Minimum Top-up Tax, paragraph 118.30.1. Background
A multinational enterprise (MNE) group subject to minimum taxation consists of constituent entities (see in particular Art. 1.1.1 and Art. 1.3 of the Global Anti-Base Erosion Model Rules of the Inclusive Framework on BEPS of the OECD1 and the G20 countries [Global Anti-Base Erosion Model Rules, GloBE Rules]2). These constituent entities are subject to the GloBE Rules and the Ordinance of 22 December 2023 on the Minimum Taxation of Large Corporate Groups (Minimum Taxation Ordinance, OMinT; SR 642.161).
The term constituent entity is defined in the GloBE Rules (see Art. 2 para. 1 and Art. 3 para. 1 of the OMinT).
According to Article 1.3.1 of the GloBE Rules, a constituent entity is any entity that is included in a group (let. a) and any permanent establishment of a main entity that is itself an entity that is included in a group (let. b). According to Article 1.3.2 of the GloBE Rules, a permanent establishment that is a constituent entity under Article 1.3.1 letter b of the GloBE Rules shall be treated as separate from the main entity and any other permanent establishment of that main entity.
The term permanent establishment is defined in Article 10.1 of the GloBE Rules. It follows in particular from this definition that only permanent establishments of foreign entities are deemed to be constituent entities. Permanent establishments of domestic entities of the MNE group concerned, by contrast, are not deemed to be constituent entities, but belong to the domestic main entity for GloBE purposes.
Constituent entities of an MNE group may be liable for top-up tax and subject to various procedural obligations (see in particular Chapters 2 and 8 of the GloBE Rules and Art. 5 and Art. 19 et seq. of the OMinT). Furthermore, under Article 6 of the OMinT, all constituent entities of an enterprise group that belong to Switzerland for tax purposes are jointly and severally liable for the amount of the top-up tax attributed to them under Article 12 of the OMinT.
2. Legal classification of permanent establishments according to Swiss law
In the present context, a permanent establishment is a purely fiscal term. Permanent establishments – regardless of whether they are registered with the commercial register as a branch or not – have no legal personality. They have neither legal capacity nor the capacity to act. In addition, they lack the capacity to be a party to legal proceedings and to take legal action. Finally, permanent establishments cannot be subject to debt enforcement proceedings. For these aspects, permanent establishments are part of the main entity.
In the case of direct federal tax, it is not the permanent establishment itself that is subject to tax; rather, if a permanent establishment exists, there is an economic affiliation in Switzerland of the individual or legal entity that is not personally affiliated in Switzerland (see Art. 4 para. 1 let. b and Art. 51 para. 1 let. b of the Federal Act of 14 December 1990 on Direct Federal Taxation [DFTA]; SR 642.11).
3. Treatment of constituent entities that are permanent establishments for top-up tax purposes
As explained in section 1, international permanent establishments are deemed to be constituent entities under the GloBE Rules. Furthermore, the GloBE Rules and the OMinT regulate the tax liability and procedural obligations in the same way for all constituent entities – regardless of whether a constituent entity is a permanent establishment or not.
However, with regard to Swiss law, the explanations in section 2 above must be observed for permanent establishments. If a permanent establishment qualifies as a constituent entity under the provisions of the OMinT and the GloBE Rules, it therefore follows from the explanations in section 2 above that the tax liability and procedural obligations under the OMinT and the GloBE Rules do not apply to the permanent establishment itself, but rather to the foreign main entity.
In the same way, liability or joint liability under Article 6 of the OMinT applies to the foreign main entity, whereby under Article 50 paragraph 1 of the Federal Act of 11 April 1889 on Debt Enforcement and Bankruptcy (DEBA; SR 281.1), debtors resident abroad who have a permanent business establishment in Switzerland may be held liable for the liabilities incurred for the account of the latter, at the registered office of the latter.
The above information applies to tax liability, procedural obligations and liability. However, this does not change the basic concept of the GloBE Rules. In particular, the principle of jurisdictional blending, the allocation rules for income and tax, and the rules on the location of entities and permanent establishments continue to apply unchanged.

Federal practices for principal companies and Swiss finance branches from 1 January 2020
As part of the implementation of the Federal Act on Tax Reform and AHV Financing (TRAF), the Federal Tax Administration will no longer apply the federal practices for principal companies and Swiss Finance Branches to companies from 1 January 2020.
In the referendum of 19 May 2019, the TRAF was adopted. As a result, the legal regulations for cantonal status companies will be abolished, among other things. On 28 September 2018, the Federal Council announced that the TRAF would enter into force on 1 January 2020. It still has to take the formal decision.
As already communicated, the regulations for principal companies and Swiss Finance Branches (federal practices) will be completely abolished in this context at the practical level as well.
Unlike the abolition of the regulations for cantonal status companies, the abolition of these federal practices does not require any legal amendments.
The federal practices on international allocation of taxes for principal companies and the Swiss Finance Branches can therefore no longer be applied by taxpayers from 1 January 2020.
