Switzerland is an attractive destination for cross-border workers due to its strong economy and high salaries. However, taxation can be a complex topic, especially as tax rules vary depending on whether you live in France, Italy, or Germany.
This guide explains everything you need to know about cross-border taxation in 2025, including where you pay taxes, how to avoid double taxation, and which tax deductions may apply.
Your tax situation depends on three main factors
Each country has a tax agreement with Switzerland, determining where and how cross-border workers are taxed. The table below summarizes the tax rules by country:
Country of Residence | Where You Pay Taxes | Key Tax Rule |
---|---|---|
France | Mostly in France | Swiss withholding tax (0% in most cantons except Geneva, which applies a 4.5% tax at source). France applies a tax credit to avoid double taxation. |
Italy | Switzerland & Italy | New agreement (since July 17, 2023) requires new cross-border workers to pay tax in both countries, but with a tax credit in Italy. Old cross-border workers remain taxed only in Switzerland. |
Germany | Mostly in Germany | A fixed Swiss withholding tax of 4.5%, but all income is fully taxed in Germany. The withholding tax is credited against German income tax. |
📌 Important: If you are taxed in Switzerland, you may need to fill out forms in your home country to prevent double taxation.
📌 Tax Tip: If you work in Geneva, you may qualify as a quasi-resident (if 90% of your income is Swiss) and apply for deductions such as transport costs, mortgage interest, and pension contributions.
The new tax agreement (since July 17, 2023) divides cross-border workers into two categories:
📌 Tax Tip: The exchange rate for tax declarations is the official annual average set by Italian tax authorities, not your bank’s rate.
Germany follows a double taxation agreement with Switzerland:
💡 Good to Know: Germany does not have a tax-free income threshold for cross-border workers. However, commuting costs and pension contributions can reduce taxable income.
If you work in Switzerland four days a week and one day remotely in Italy, France, or Germany, your tax status remains unchanged.
However, if you work more than 25% remotely from Italy, or 40% remotely from France, your salary may become fully taxable in your home country.
When declaring Swiss income in your home country, you must convert CHF to EUR using the official exchange rate determined by tax authorities.
📌 Tip: Do not use your bank’s conversion rate for tax declarations! Instead, check your country’s official exchange rate for the tax year.
Cross-border workers often receive their salary in CHF but pay expenses in EUR. However, banks typically apply high fees and unfavorable exchange rates, reducing your take-home pay.
🎯 Smart exchange tip: Instead of letting your bank handle conversions at poor rates, use a specialized service like ibani for better conditions:
