Tax When Leaving Switzerland

How your tax liability changes when you leave Switzerland

Swiss residents are taxed on their worldwide income and wealth for as long as they are considered tax resident in a canton. Tax resident status generally ends on the date you deregister from your commune of residence and genuinely settle elsewhere, not on the date you decide to move.

Because Swiss cantons assess tax on the calendar year in which you actually lived there, leaving partway through the year does not mean you owe a full year of tax. Instead, your Swiss-source and worldwide income and wealth are apportioned to the period you were resident, and your tax rate is generally still calculated with reference to your full-year situation, which can produce results that surprise people who expect a simple pro rata reduction.

• •Tax liability normally ends on the date recorded as your official departure from the commune
• •The tax period that year covers only the months of actual residence, not the full calendar year
• •Swiss-source income or assets kept after departure can create a separate, limited tax liability

Filing your final or intermediate tax return

Departure triggers a final (sometimes called intermediate) tax return for the part of the year you were resident. The cantonal tax office that has jurisdiction over your last commune of residence handles this return, and procedures and forms differ from canton to canton.

In practice, deregistering with your commune (the administrative step confirming your departure) is usually what prompts the tax office to open your final assessment. It is worth doing this formally and promptly, because an incomplete or missing deregistration can leave your file open longer than necessary and create confusion about which tax period still applies to you.

Keep records of your departure date, your last payslips, any severance or bonus payments, and statements for bank accounts, securities and property, since all of these typically need to be reported for the final period.

Withholding tax at source and your departure

If you are a foreign employee without a settlement (C) permit, Swiss withholding tax (impôt à la source / Quellensteuer) is deducted directly from your salary each month by your employer, based on your circumstances and canton of work. This system continues to apply for as long as you remain employed and resident in Switzerland.

When you leave, withholding tax on your final salary, bonus or severance payments is calculated in the ordinary way up to your last payroll date. Depending on your income level and canton, you may also be entitled to request a correction of the withholding tax already deducted during the year, for example if deductions you were entitled to were not reflected in the standard tariff applied by your employer. Deadlines for such a request are strict and vary by canton.

Pension assets: your 2nd pillar and pillar 3a when you leave

Occupational pension (2nd pillar) savings held in a Swiss pension fund or vested benefits account are treated separately from your ordinary income tax. If you leave Switzerland permanently, you can generally request payment of your vested benefits, but the amount you can withdraw in cash depends on where you are moving to.

If you move to a country in the European Union or EFTA and will be subject to compulsory pension insurance there, only the extra-mandatory portion of your 2nd pillar savings can normally be paid out in cash; the mandatory portion has to stay in a Swiss vested benefits account or policy until your ordinary retirement age. If you move outside the EU/EFTA, the full vested benefit can typically be paid out on departure.

Any lump-sum payment from a 2nd pillar fund or from a pillar 3a account is subject to a separate withholding tax at source, applied by the canton where the paying pension fund or foundation is registered rather than the canton where you lived. Because this can differ significantly from your income tax canton, it is worth checking before you finalise the timing of a withdrawal.

What can continue after you leave Switzerland

Leaving Switzerland ends your unlimited tax liability, but it does not automatically end every link to the Swiss tax system. If you keep real estate, a business interest or certain other Swiss-source assets, you generally remain subject to a limited tax liability on that specific income or wealth, with a simplified return covering it each year.

Bank accounts, securities held with a Swiss institution, or a Swiss employer who continues to pay you after departure can also have reporting consequences on both the Swiss and the new country side. Coordinating the two systems is where a tax consultant becomes useful, since My Swiss Relocation does not provide personal tax advice directly but works with qualified specialists on this kind of cross-border question.
