The word "tax" in Switzerland hides a trap: there is no single Swiss tax. You pay the Confederation, your canton and your commune, each with its own rules, and a cantonal wealth tax on top. For a newcomer this sounds worse than it is: if you are a foreign employee, your employer takes taxes in Switzerland off your salary before you see it. What matters is knowing when that stops being true. Here is the system as published by the Federal Tax Administration (FTA) and the cantons.
Who pays tax in Switzerland?
You are taxable on your whole income in Switzerland if you have your tax domicile there, meaning you live in Switzerland with the intention to settle for the long term. You are also taxable if you stay without notable interruption for 30 days while working, or 90 days without working (article 3 of the federal tax act, LIFD). Your domicile decides your canton and your commune of taxation, so registration at the commune is the starting point (see moving to Switzerland: the step-by-step guide).
What are the three levels of taxes in Switzerland?
- Federal direct tax: rates are low. For 2026, a single person pays nothing up to CHF 15,200 of taxable income (CHF 29,700 for a married couple), then about CHF 401 at CHF 50,000 and CHF 2,684 at CHF 100,000, according to the FTA scale, up to a flat 11.5% at high incomes. Couples and single-parent families have a lighter scale, and there is a tax reduction of CHF 263 per child. Federal deductions in 2026 include CHF 6,800 per child and up to CHF 3,300 for commuting costs for an employee.
- Cantonal and communal taxes: set locally. Geneva, Vaud and Zurich have very different scales. They also include a wealth tax, and foreign accounts and investments count.
- Church tax: cantonal rules. In Zurich, the parishes of the recognised churches (Reformed, Roman Catholic, Christian Catholic) levy church tax on their members. In Geneva there is no church tax: the voluntary religious contribution is a donation, not a tax, which you choose to pay or not; the cantonal tax administration calculates an indicative amount on request.
What is source tax in Switzerland?
If you are a foreign employee living in Switzerland without a C permit, your employer withholds the tax at the source and pays it to the canton. The scale is fixed by each canton. You do not normally fill in a return. Source taxation ends when you obtain a C permit, or when you marry a Swiss citizen or a C permit holder (article 12 of the FDF ordinance); from then on you receive a return each year.
This is why many newcomers' first payslip shows a deduction that looks large. It is not an extra: it is the income tax, taken in advance.
How do you move to an ordinary return?
You can ask for an ordinary subsequent assessment (taxation ordinaire ultérieure) from the tax office of your canton. The deadline is 31 March of the following year, and the FTA states that it cannot be extended: a late request is not considered. Why do it? Because without it, source tax stands in for the income tax and no further deductions, such as pillar 3a contributions or actual costs, are granted. Once requested, the ordinary assessment continues every year until your source taxation ends, and the request cannot be withdrawn.
There is a hard stop: from CHF 120,000 gross salary in a tax year, the ordinary subsequent assessment becomes compulsory, and it stays compulsory until your source taxation ends, even if your salary falls afterwards (article 9 of the FDF ordinance). For a married couple, one partner reaching the amount is enough.
Source tax, a partner abroad, a second income or a move between cantons can change which rule applies to you. Moovy, our AI assistant, can help you list the documents to ask your employer and the questions to put to the cantonal tax office, but your canton decides your tax.
Which situation are you in for taxes in Switzerland?
| Your situation | What generally applies |
|---|---|
| Employee with an L or B permit | Source tax withheld by your employer; ordinary assessment on request by 31 March of the following year |
| Gross salary of CHF 120,000 or more in a tax year | Ordinary subsequent assessment is compulsory |
| Holder of a C permit, or married to a Swiss citizen or C permit holder | Annual tax return |
| Self-employed | Your profit is added to your income and you file a return; a company pays profit tax |
| Living abroad, working in Switzerland | The treaty with your country decides where you are taxed; ask the canton where you work, and see working in Switzerland |
Use the table as a map, then check your canton's page. The FTA's source tax page and your cantonal tax office are the authorities.
What are the filing deadlines?
They differ by canton:
- Geneva: 31 March, even if you are not taxable; an extension can be requested.
- Vaud: 15 March (the 2025 return was due 15 March 2026), with an extension request possible online until 30 June.
- Zurich: 31 March (the 2026 return is due 31 March 2027); an extension has to be requested before the deadline, as late requests are not considered.
Returns are filed online with the canton's software, such as GeTax in Geneva. Prepare your salary certificate, your pillar 3a and pension fund certificates, health insurance premiums and the bank and wealth statements at 31 December. Then pay the instalments the canton asks for, and the balance when the assessment arrives.
What can you deduct, and what is pillar 3a?
The third pillar is a voluntary retirement saving scheme with a bank or an insurer. In 2026 you can pay in and deduct up to CHF 7,258 if you belong to a pension fund, or 20% of your income from work with a ceiling of CHF 36,288 if you do not, according to the Federal Social Insurance Office. These limits are adjusted from time to time, so check the year's figures. The deduction works only if you are taxed in the ordinary procedure, which is one reason some newcomers request the subsequent assessment. Check the effect before you open an account.
How should you prepare your first tax year?
- Keep your payslips and the employer's salary certificate. It is the base document of any return.
- Note your permit type and the date you took up residence, since they decide if you are taxed at source.
- Decide before 31 March whether to request an ordinary assessment: compare the deductions you would claim (pillar 3a, actual expenses, children) with what source tax already gives you.
- Gather your statements at 31 December: bank, investments, pension fund, health insurance premiums.
- Ask the cantonal tax office which online software and which deadline apply to you, and how an extension is requested.
Then put the dates in your calendar. In Switzerland, missing a tax deadline is an administrative problem that is easy to avoid and annoying to repair.
What about the wealth tax?
Cantons tax net wealth as well as income, on a progressive scale set by each canton, with a multiplier applied by your commune. Bank accounts, investments and property abroad count, so list them when you file. For people with large assets, the wealth tax is one of the main reasons to compare communes before settling: use the FTA calculator with your own figures. It is also the reason some wealthy newcomers ask about lump-sum taxation, which only some cantons offer to foreigners who do not work in Switzerland; Zurich, Basel-Stadt, Schaffhausen and Appenzell Ausserrhoden have abolished it.
What are the common traps?
- Missing 31 March. After this date you remain taxed at source for that year.
- Thinking source tax is final in all cases. From CHF 120,000 gross, ordinary assessment is compulsory.
- Forgetting the wealth tax. Accounts and investments abroad count.
- Comparing only salaries between cantons. At equal pay the total tax changes with the canton and the commune.
- Ignoring your home country's rules. Switzerland has tax treaties with all EU countries and the UK, which decide who taxes what. Retirees can read retire in Switzerland for how pensions are treated.
Before you decide on a canton, a pillar 3a account or a request for ordinary assessment, have your situation confirmed by a tax adviser or a fiduciary in your canton, or by the cantonal tax office itself.
