Social security aspects of home office
Home office work, which was imposed by the authorities during the pandemic, gave an additional boost to teleworking and the associated flexibilization of work. Even after the pandemic, home office remains widespread in many areas. Employees appreciate the new flexibility and no longer want to do without it. This also applies to the numerous cross-border commuters. The following article clarifies social security issues in connection with home office, especially in cross-border situations.
Combating the misuse of letterbox companies
On 22 December 2021, the European Commission published a draft directive to combat the abusive use of letterbox companies within the EU.

Taxation of the Digital Economy - OECD Agreement on Global Tax Reform (Pillar One and Two)
137 countries of the Organization for Economic Co-operation and Development (OECD) - including Switzerland - agreed to a comprehensive global tax reform on 8 October 2021. The global tax reform aims to introduce a worldwide redistribution of profits of multinational corporations with a turnover of more than 20 billion euros (Pillar One) and a global minimum taxation of 15% for multinational corporations with a turnover of more than 750 million euros (Pillar Two). The implementation of the reform will pose major challenges for companies, but also for states. Pillar One will result in multinationals becoming taxable in a state even if they have no physical facilities such as offices or premises in that state. At least 25% of profits exceeding 10% of turnover will be taxed in the states where the turnover is generated, irrespective of the existence of a physical presence. Pillar Two will introduce a global minimum tax of 15%. The tax rate will be calculated at the state level and not at the individual company level. In addition, the calculation of the global minimum tax will be based on taxable profit and taxable net income, an international accounting standard and not local legislation, such as Swiss commercial law. This article explains how Pillar One and Two work, the currently envisaged implementation of the reform in Switzerland, its impact on global tax and location competition and on Swiss-based companies.
Extraterritorial change of status through the introduction of the Income Inclusion Rule
With the introduction of the Income Inclusion Rule (IIR), Switzerland must in future also tax previously untaxed hidden reserves and goodwill of low-taxed or non-taxed foreign subsidiaries upon realisation that were created before 1 January 2024. This will result in a change of status analogous to STAF. This paper is a thought experiment on whether this change of status would not also have to result in a step-up for profit tax purposes from a constitutional and tax system point of view.
