If you are planning a tax return in Switzerland as an expat, the good news is that the first year follows a clear order. Some newcomers never fill in a return at all, because tax is taken from the salary every month. Others receive a form and wonder where to start. This guide shows which path usually applies, what to prepare before you leave, and what happens after you arrive.
Two ways to be taxed: at source or by ordinary return
Switzerland has two main systems for people who earn a salary.
- Tax at source (Quellensteuer, impôt à la source): the employer deducts tax from each paycheck and pays it to the canton every month.
- Ordinary assessment: you receive a tax form from the canton, declare income and assets yourself, and the canton issues a bill.
Foreign nationals without a C permit (the settlement permit) are taxed at source. With a B or L permit and income below CHF 120,000, tax at source is in principle final, and an ordinary assessment can be requested later. From CHF 120,000, a later ordinary assessment is compulsory (source: Federal Tax Administration (FTA)). The details of each canton differ, so the local tax office has the last word. For a deeper look at the deduction itself, see tax at source.
Which permit you hold depends on the authorities, and the rules differ for EU/EFTA nationals and for people from third countries. If you are not sure where you stand, the permit finder gives a first idea.
What a first year often looks like
Here are three fictional examples, to show how different the first year can be.
- A couple from Manchester, one partner employed by a Swiss company. The employer deducts tax at source. The couple files nothing in the first year unless the canton asks.
- A family of four from Singapore, with a salary above the threshold above. Tax is taken at source, and an ordinary return follows because the income is high.
- A freelancer from Toronto who works for herself. There is no employer to deduct anything, so the canton usually sends a tax form after arrival.
None of these is a forecast. Each person's situation depends on permit, income, canton and marital status, and a specialist can look at it once you send a request.
The order of steps, from home to the first return
Before you leave: what to prepare at home
A tidy folder now saves stress later. Even if you are taxed at source, the canton may ask for details.
- Salary statements and any bonus records from your last year abroad.
- Bank and investment statements, with balances at the date of your move.
- Details of property or a pension you own abroad.
- Marriage and birth documents, which show who counts as a dependent.
- Your Swiss employment contract, once signed.
Keep scanned copies in one place. Documents in English are usually easy to deal with. Other languages may need a translation, depending on the canton. The personal checklist tool can turn this list into your own plan.
After you arrive: registration comes first
Tax is linked to where you live. The first official step is to register with the commune, which usually happens within 14 days of arrival (source: ch.ch). The exact period can vary by commune and canton, so ask the local office. At the counter, the usual items are your ID, your residence or work permit, and proof of health insurance.
Basic health insurance is compulsory within three months of taking up residence, and cover starts back at the date of arrival if that period is respected (source: Federal Office of Public Health (FOPH)). Our page on health insurance for newcomers walks through it. For the wider arrival sequence, the relocation calendar puts each step in order.
If an ordinary return comes: what the form asks
When a return does arrive, it is mostly a list of questions you can answer from your folder.
- Personal details: family situation, children, religion in some cantons.
- Income: salary, self-employment, rental income, foreign income.
- Assets: bank accounts, securities, property, vehicles, with values at year end.
- Deductions: items such as contributions to pension schemes and certain costs. Which ones apply depends on the canton.
- Supporting documents: salary certificate, bank statements, insurance and pension confirmations.
The pension side is explained in AVS and the three pillars. For a sense of what salaries look like, see what people earn in Switzerland.
Deadlines and online filing tools are set by each canton, so check the notice that comes with the form. An extension is often possible if it is requested in time. Late filing can lead to a reminder or a fine, depending on the canton.
Common pitfalls
- Assuming tax at source ends all paperwork. The canton may still ask for a return in some cases.
- Forgetting foreign assets. Accounts and property abroad are generally part of the picture.
- Mixing up years. The first year is often a partial year, because you arrive mid-year.
- Ignoring letters in the local language. A tax letter is official mail, even when it looks routine. Translate it quickly.
- Expecting a copy of your home-country rules. Tax at home may follow different logic, for example on residence or citizenship. A specialist can explain how the two sides interact.
Some people also hear about special regimes for wealthy newcomers. That is a separate topic, covered under lump-sum taxation.
Comparing with home
Newcomers from the UK or the US often ask how the system differs from theirs. The big difference is that the canton and the commune, not only the federal state, set tax. Moving to a different canton can change the bill. Our pages on Switzerland or the UK and Switzerland or the US give a broader picture of costs, and the cost of living page adds context.

Frequently asked questions
Do expats have to file a tax return in Switzerland?

Does my employer file my return?
No. The employer handles the deduction at source, but a personal return is your own matter.
When does my first return arrive?
The canton decides. It usually comes after your first period of residence. Ask the local tax office.
Is the Swiss tax year the calendar year?
In general, yes, but the first year is often partial because of your arrival date.
Who sets the tax rate?
The Confederation, the canton and the commune each levy tax. The total depends on where you live.
Does my canton matter?
Yes. Rates, deductions, forms and deadlines vary from one canton to another.
Do I register with the tax office myself?
Usually the commune registration passes your details on. Ask your commune what else it needs.
What documents do I bring from abroad?
Income and asset records, civil status documents, and your contract. The list above gives more detail.
Are foreign bank accounts declared?
In an ordinary return, assets are generally listed, including those abroad. A specialist can explain the details.
Does my spouse file separately?
Married couples are normally assessed together under the ordinary system. The canton gives the exact rule.
What about children?
Children are listed on the return and can affect the amount of tax. Rules differ by canton.
Can I get a deadline extension?
Often yes, if the request is made in time. The notice that comes with your form explains how.
What if I miss the deadline?
The canton may send a reminder or a fine. Contact the tax office as early as possible.
Is health insurance part of the tax return?
Insurance is a separate topic, though some costs may appear in the return. Basic cover is compulsory within three months of arrival (source: Federal Office of Public Health (FOPH)).
Do I pay tax twice, at home and in Switzerland?
Tax treaties often aim to prevent that. How it works for your home country is a question for a specialist.
Is a tax adviser worth it?
For a simple salary case, perhaps not. For several incomes, property or assets abroad, many newcomers find advice useful. Send a request and a specialist can look at your situation.
What if I leave Switzerland later?
A final return or a deregistration step is part of leaving. See leaving Switzerland.
