Tax Knowledge
Germany–Switzerland Tax Guide
Understand German tax obligations when living, working, investing or doing business across the German–Swiss border. Explore the relevant topics, common situations and practical preparation steps.
Overview
German Tax Issues with a Swiss Connection
A residence, workplace, business, investment account, property or retirement benefit in Switzerland can have tax consequences in both Germany and Switzerland.
This tax knowledge section examines such cases from the German perspective: which tax obligations arise or continue in Germany, which taxing rights belong to Switzerland, and how the two tax systems are coordinated.

Key Tax Checks
Six Distinctions That Matter Across the Border
1. Establish Domestic and Treaty Residence
Deregistering or obtaining a Swiss residence permit does not by itself end German worldwide income tax liability. A retained German home or habitual abode may preserve it. Domestic residence, treaty residence and continuing German taxing rights require separate analysis.
2. Commuter Status Changes Salary Taxation
A qualifying commuter resident in Germany is generally taxed there under Article 15a. With the required residence certificate, Swiss withholding is limited to 4.5% of gross remuneration and is credited in Germany. This is not the total tax burden. Home-working days do not automatically require a workday split.
3. Social Security Follows Separate Rules
Where EU–Switzerland coordination applies, a German resident working for one Swiss employer may generally remain insured in Switzerland with less than 25% telework in Germany. At 25% to less than 50%, the telework framework requires an application and all its conditions to be met. Exactly 50% is outside that framework.
4. Check Shares and Funds for Exit Tax
Section 6 AStG can apply to qualifying company shareholdings. Separate rules in section 19(3) InvStG can also affect certain privately held investment fund interests. Not every portfolio triggers exit tax: residence history, holding size, acquisition cost and the specific triggering event must be checked.
5. Swiss Pension Benefits Need Classification
AHV, occupational pensions and Pillar 3a are not interchangeable for German tax purposes. Occupational benefits may require a split between mandatory and extra-mandatory components. Recurring pensions, lump sums, public-service rules and residence at payment can lead to different results.
6. Inheritances and Gifts Need Their Own Treaty Review
The income tax treaty does not resolve inheritance and gift tax. Germany and Switzerland have a separate estate and inheritance tax treaty. Ordinary lifetime gifts are generally outside its scope; specific arrangements, including business transfers, require separate consideration. German and Swiss cantonal tax rules must also be reviewed.
Use the Treaty Version Applicable to the Tax Year
The amending protocol signed on 21 August 2023 entered into force on 27 November 2025. Most changes apply from 1 January 2026. Employment cases now require particular attention to the protocol rules on regular commuting, non-return days and actual workday allocation. Earlier years must be assessed under the rules applicable at that time.
