As a foreign physiotherapist in Switzerland, one deadline comes round every year: your tax return. For many European physios who have moved over, it's a puzzle full of new rules and requirements. Here's what you need to know to handle it without the headache.
The basics of Swiss tax filing
In Switzerland, every resident over 18 has to file an annual tax return. As a foreign physio you become liable for Swiss tax as soon as you establish your residence here. You're required to declare your worldwide income and assets.
Key deadlines
In most Swiss cantons your return has to be in by 31 March of the following year. Good news: in most cantons you can request an extension, often until November or even December, which gives you time to sort everything out properly. Miss the deadline and you'll get a reminder and potentially a fine. The exact rules vary by canton, so check the specifics for where you live.
Withholding tax vs. a voluntary return
As a physio with a B residence permit (Aufenthaltsbewilligung B), you don't technically have to file a return if you earn less than CHF 120,000 gross per year. Instead, monthly withholding tax (Quellensteuer) is deducted automatically.
But this is an opportunity worth taking. Even though it's not mandatory, it can really pay off to file a regular return anyway. Many foreign professionals pay more through withholding tax than they would under a regular filing, because a regular return lets you claim more deductions like:
- Contributions to your third pillar (3a).
- Health costs not covered by insurance.
- Commuting expenses.
- Professional costs, including continuing education.
- Donations to recognised charities.
If you want to take this route, you have to submit an application to your canton's tax authority (Finanzdepartement) by 31 March to file a regular return.
Tip: use the official Swiss tax calculator to estimate whether it's worth it. Compare the outcome with what you've already paid in withholding tax to see if a regular return makes sense for you.
What you need for your return
To fill in your Swiss tax return properly, you'll need:
For income and assets
- Pay slips and annual summary from your employer.
- Bank statements for all your accounts, including any abroad.
- Overview of securities and investments.
- Information about any rental income.
For possible deductions
- Health costs not covered by insurance.
- Proof of Pillar 3a contributions.
- Commuting expenses.
- Professional costs, including continuing education.
- Donations to recognised charities.
If you own property in Switzerland, you'll also need documents for the property itself, mortgage rates and maintenance costs.
Deductions you shouldn't miss
- Commuting: you can deduct daily travel costs to work, though each canton has a maximum.
- Professional costs: expenses for professional literature, continuing education and work-specific clothing are deductible.
- Retirement savings: Pillar 3a contributions are fully deductible up to the annual max (CHF 7,056 in 2025 for employees).
- Healthcare costs: medical costs not covered by insurance are deductible if they exceed 5% of your net income. This includes dental.
- Donations: gifts to recognised Swiss charities are deductible up to 20% of your net income.
If you work or live across multiple cantons, your tax situation gets more complex. In that case, professional advice is worth extra.
Digital or paper?
Most cantons now offer digital filing, and it's usually faster and easier than the paper form. The cantonal tax authorities provide free software you can download.
Pitfalls to avoid
- Forgotten foreign accounts: bank accounts you still hold in your home country have to be declared.
- Not all income reported: every income stream, including from your home country or other countries, needs to be declared.
- Missed deductions: many foreign professionals don't use all the options Switzerland offers.
- Missed deadlines: filing late can result in fines.
