You commute daily between Germany and Switzerland for work — and then you come across the "60-day rule" and its consequences for your taxes. What is it all about? When do you lose your cross-border commuter status? And how does working from home affect things?
The 60-day rule is one of the most frequently misunderstood provisions in the double taxation agreement (DTA) between Germany and Switzerland. This article explains everything clearly, completely, and practically for 2026.

Who qualifies as a cross-border commuter?
A cross-border commuter within the meaning of the Germany-Switzerland DTA (Art. 15a) is a person who:
- Lives in a municipality in Germany that is generally within 30 km of the Swiss border (more precisely: in the so-called "border zone"), or
- Has their place of residence outside the border zone but commutes daily to work in Switzerland and returns home regularly
The decisive characteristic is regular daily return — not necessarily the distance. The Germany-Switzerland DTA defines cross-border commuters more broadly than is often assumed: even someone living in Stuttgart and commuting daily to Basel can qualify as a cross-border commuter.
Cross-border commuters under the Germany-Switzerland DTA are taxed in Germany — not in Switzerland. Switzerland may only withhold a withholding tax of a maximum of 4.5%. Germany credits this withholding tax against German income tax. Because Germany generally has higher tax rates, cross-border commuters effectively pay German taxes.
The 60-day rule explained
The 60-day rule lies at the heart of Art. 15a of the Germany-Switzerland DTA. It stipulates:
An employee loses their cross-border commuter status for the entire tax year if, during that year, they fail to return to their place of residence on more than 60 working days — i.e. they stay overnight in Switzerland or do not commute for other reasons (home office, business trip abroad).
The 60 days refer to the entire calendar year, not to individual months. Someone who exceeds the limit in August due to many business trips loses their cross-border commuter status retrospectively for the entire year — not just for August.
What exactly is a "non-return day"?
A non-return day arises when, on a working day, you:
- Stay overnight in Switzerland (e.g. shift work, late-night events, business trip to Switzerland)
- Work from home in Germany and do not travel to Switzerland
- Are on a business trip abroad (do not enter Switzerland)
- Attend a training course outside Switzerland
What counts as a non-return day?
Overview: what counts as a non-return day?
Holidays, sick days, public holidays, and part-time days off are not working days and therefore do not count towards the 60 days. Only working days on which you do not commute to Switzerland are relevant.
Home office and the 49.9% rule (supplementary agreement 2024)
With the entry into force of the supplementary agreement to the Germany-Switzerland DTA (2024), the home office situation for cross-border commuters was regulated considerably more clearly. The key point:
Cross-border commuters may work up to 49.9% of their working time from home in Germany without losing their cross-border commuter status — provided the total number of non-return days remains below 60 per year. Home office income is taxed in Germany; the remaining income continues to be subject to German taxation under the cross-border commuter article.
Example: what is permitted?
Max works 5 days per week, i.e. approximately 230 working days per year. He may:
- Work up to 49.9% from home = approx. 114 home office days per year — without losing cross-border commuter status
- However: the total non-return days (including home office and others) must not exceed 60 overall
In practice, this means: someone working 3 days per week from home (60% = above the 49.9% limit) loses their cross-border commuter status — even without staying overnight. Both the 49.9% limit and the 60-day limit must be observed.

What happens if you exceed the limit?
If you exceed the 60-day limit, you lose your cross-border commuter status for the entire tax year. This has the following consequences:
| Situation | With cross-border commuter status | Without cross-border commuter status |
|---|---|---|
| Right to tax | Germany (with Swiss withholding tax of max. 4.5%) | Switzerland has full right to tax Swiss employment income |
| Swiss withholding tax | 4.5% (on Swiss salary) | Normal withholding tax rate (depending on canton: 10–30%+) |
| German tax | Normal German tax rate, minus Swiss withholding tax | Only on German income (Swiss salary taxed by Switzerland) |
| Effective tax burden | Generally higher (German tax level) | Generally lower (Swiss tax level) |
| Tax return | In Germany (worldwide income taxation) | In Switzerland (on Swiss income); Germany only for German income |
If you lose your cross-border commuter status, your Swiss income is taxed in Switzerland. Since Swiss tax rates are lower than German rates for many income levels, this can actually be more favourable depending on your place of residence and income. Work out your specific situation — ideally with a tax adviser.
Withholding tax: what cross-border commuters pay
As a cross-border commuter with cross-border commuter status, your Swiss employer withholds a withholding tax of 4.5% from your monthly salary and remits it to the Swiss tax authorities. Germany credits this tax against your German income tax. The practical process:
- You receive a certificate from your employer confirming the withholding tax deducted
- You attach this certificate to your German tax return
- The tax office credits the CHF withholding tax (converted to EUR) against your German tax bill
- You effectively pay German income tax (less the Swiss withholding tax)
Swiss withholding tax rates for cross-border commuters 2026
The rate is set out in the Germany-Switzerland DTA and applies to all standard cross-border commuters (Art. 15a DTA). Other income (e.g. bonuses, pension fund lump-sum payments) may be taxed differently. Source: ESTV — Withholding Tax
Documentation: how to protect yourself in a tax dispute
In a dispute with the tax authorities, the burden of proof lies with the cross-border commuter. You must be able to demonstrate that you have observed the 60-day limit. The following documents are crucial:
- Working time records / time-recording system: electronic time recording at the Swiss office is the strongest evidence
- Access logs: badge data at the Swiss employer
- Expense claims: proof of journeys to Switzerland
- Email metadata: emails sent from the Swiss office network (with timestamp and IP address)
- Home office calendar: monthly overview of home office days (must be kept on an ongoing basis)
- Employer confirmation: annual certificate from the employer showing working days in Switzerland versus home office days
Do not start your diary in autumn. Keep your home office calendar daily. Tax authorities frequently refuse to accept reconstructed records as evidence.
Does the 60-day rule apply to Austria and France too?
The exact rules vary depending on the DTA:
- Austria-Switzerland DTA: A similar cross-border commuter concept applies here, but with its own provisions. Austrian cross-border commuters are generally taxed at source in Switzerland, with a separate equalisation agreement. The 60-day rule in the German sense does not exist here.
- France-Switzerland DTA: France and Switzerland have a special cross-border commuter agreement with a border zone (French border zone: certain départements). Cross-border commuters are taxed in France; Switzerland retains a lump-sum tax. The home office rule was adjusted in 2023.
- Italy-Switzerland DTA: A new agreement for Italian-Swiss cross-border commuters has been in force since 2024. Swiss companies have since been required to withhold a withholding tax as well.
Every DTA is different. If you are a cross-border commuter and not from Germany, find out specifically about the DTA between your country of residence and Switzerland — the rules can differ considerably.
