Leaving Switzerland in 2026: the departure checklist, from notice period to final transfer

A move to Switzerland can be caught up on: if you forget a step, you do it the following month. Leaving Switzerland cannot. Four financial decisions have to be made while you are still domiciled in the country, and they become irreversible the day your address moves abroad. This guide deals with those first, then sets out the administrative timeline. If you are making the journey the other way, our checklist for moving to Switzerland covers the arrival.

1. The four irreversible decisions

They have one thing in common: they cost little to deal with in advance, and a lot to discover afterwards. None of them is self-evident, and each contradicts a common intuition.

1.1 Your 2nd pillar may not follow you

This rule depends entirely on your destination country. If you leave Switzerland for a country outside the EU and EFTA, the whole of your pension capital can be paid out to you in cash. If you leave for an EU or EFTA country and become subject to compulsory social insurance there — which is in principle the case as soon as you take up gainful employment — only the extra-mandatory portion can be paid out to you. The mandatory portion stays in Switzerland, on a vested benefits account or policy, and only becomes available from five years before the reference age.

The legal mechanism rests on two texts: article 5 of the Federal Vested Benefits Act allows a cash payment to anyone permanently leaving Switzerland, and the Agreement on the Free Movement of Persons restricts its scope for the EU and EFTA. The practical consequence is that you must choose your vested benefits foundation before you go: failing instructions from you, the capital is transferred automatically to the Substitute Occupational Benefit Institution, as our guide to the vested benefits account explains. The detail of the scenarios and of the taxation of the withdrawal is set out in our 2nd pillar guide.

1.2 Your OASI contributions will not be refunded

It is often assumed that one will recover, one way or another, what has been deducted from the payslip for years. That is not the case. Nationals of the EU and EFTA, like those of all states bound to Switzerland by a social security agreement, cannot ask for their OASI contributions to be refunded when they leave the country.

The reason is coherent, even if it disappoints: the agreement guarantees that the pension will be paid abroad when the time comes. The contributions therefore do not vanish, they are frozen until retirement age, and the Swiss pension will be added to the one from your new country. A refund only exists for nationals of a state without an agreement with Switzerland; it is then claimed from the Swiss Compensation Office and paid without interest. In every case, keep a record of your OASI number and of your contribution years: that is what will make it possible to reconstruct your entitlement thirty years later.

1.3 Your 3rd pillar will be taxed where the foundation is based, not where you live

A pillar 3a withdrawal is possible when you leave Switzerland permanently, on production of the departure certificate and proof of an address abroad. It triggers a withholding tax levied at the moment of payment — and this is where the arbitrage lies: the rate depends on the canton where the pension foundation has its registered office, not on your canton of residence nor on your future country of residence.

Depending on the situation, the gap between cantons may be wide enough to make a change of foundation worth examining before departure. But the operation has to be steered while you are still domiciled in Switzerland: once you have gone, the transfer becomes laborious at best and impossible at worst, and some institutions impose a minimum holding period before releasing the capital. Depending on the double taxation treaty between Switzerland and your destination country, this withholding tax can then be the subject of a refund claim — a step taken from abroad, which assumes you have kept the tax statement.

1.4 Your C permit can outlive your departure by four years

This is the good news of a departure, and it calls for reading article 61 of the Federal Act on Foreign Nationals and Integration carefully. The departure notification itself ends the permit: the six-month period that is often quoted — three months for a short-stay permit — only concerns someone who leaves Switzerland without declaring their departure. In other words, the step that all the rest of this guide recommends you take is also the one that extinguishes your permit. Hence the value of the exception opened by the same article: on request, a settlement permit can be maintained for four years.

The request is in principle filed before departure, with the cantonal migration authority, practice varying from canton to canton. It assumes a genuine intention to return within the period, and it is not automatic. It only concerns the C permit: a B permit lapses with no equivalent. But for anyone leaving on a fixed-term assignment, a contract of a few years or simply the possibility of a return, it changes everything: without it, coming back means rebuilding a C permit from scratch, with the years of prior residence that implies.

2. The timeline, from D-90 to the final days

The rest of a departure is a matter of contractual and administrative deadlines. None of them is treacherous taken on its own; it is the way they overlap that creates the oversights. Here is the order in which they fall due.

Two remarks on this table. First, the departure notification is not the first step of the timeline but the most structuring one: the certificate it triggers is a precondition for the health insurer, the pension fund, the 3rd pillar foundation and the tax authority, so that nothing can be finalised before it. That is why it appears here at D-30 even though the minimum required deadline is shorter. Second, the radio and TV licence fee is one of the rare items that settles itself — Serafe bills on the basis of the data supplied by the residents' registry offices, so that notifying your departure to the municipality is in principle enough to stop the billing. If a bill nevertheless arrives after departure, it is the municipal register entry that needs correcting.

3. What is left to do from abroad

Four matters survive the move, and they involve the largest amounts.

The payment requests. They can only be filed once the departure certificate has been obtained and the address abroad evidenced — that is, in practice, after departure. Allow a few weeks of processing for the 3rd pillar as for the payable portion of the 2nd pillar, and bear in mind that the two institutions work separately: two files, two timetables, two payments.

The tax return for the year of departure. It covers the period from 1 January to the date of departure: income actually earned over that fraction of the year, assets assessed as at the day of departure. It arrives after you have left, at the address you will have given — hence the value of passing your new address on to the canton. One point often discovered too late: payments made after departure remain subject to Swiss withholding tax. A bonus, a holiday balance or a severance payment made after you are deregistered will be taxed in Switzerland, even though you are no longer resident there.

Refund claims based on a double taxation treaty. The withholding tax levied on a 3rd pillar withdrawal, or on the portion of 2nd pillar paid out, can be the subject of a refund claim under the treaty between Switzerland and your country of residence. This is done from abroad, within varying deadlines, and it requires the original tax statements. Keep them.

What becomes of the Swiss bank account. Nothing obliges you to close it, but few banks keep it on the same terms: non-resident pricing applies as soon as the address moves abroad, with higher account maintenance fees and sometimes a minimum deposit. If a mandatory portion of 2nd pillar stays in Switzerland, it does not need this account: it sits on a vested benefits account, which is a separate product. The real question is the comparative cost — keeping an account open for years versus paying for an international transfer the day you need one.

The item nobody quantifies: the cost of converting

A departure concentrates into a few weeks amounts of a completely different order of magnitude from a monthly salary: the current account balance, the rental deposit returned, the 3rd pillar withdrawn, the extra-mandatory portion of the 2nd pillar. Added together, they often make up the largest cross-border transfer of a lifetime.

And this is where the arithmetic turns brutal. On capital of CHF 100,000, one percentage point of margin (1%) comes to CHF 1,000 — on a different scale from the administrative fees of a departure. The logic is the same as for a salary, described in our guide to transferring your Swiss salary, but the scale changes everything: what is counted in tens of francs on a monthly payslip is counted in thousands on departure capital. The rate shown by a retail bank is never the interbank rate, and the gap is measured as a percentage of the amount transferred, not in fixed fees — which is precisely why it goes unnoticed on small amounts and becomes decisive on large ones. You can compare orders of magnitude on our real-time CHF/EUR converter.

For operations whose date is already known — a rental deposit you know will be returned on a given date — our guide on whether you can lock in an exchange rate sets out the conditions in which that makes sense.
