An assignee who holds a Swiss permit and takes up residence in another canton creates a chain of administrative effects. The employer is usually the party that feels them first: payroll, insurance records and the immigration file all change. This page explains how to change canton on a Swiss permit from the employer's side, and which questions the cantonal authorities answer.
Switzerland is a federation. Residence permits are issued under federal law, but cantons run the migration offices, collect most taxes and set many practical rules. A move across a cantonal border therefore changes who administers your transferee, even though the national framework stays the same. For the wider picture, see the cantons overview.
Why the canton matters for a permit holder
A residence permit is linked to the place of residence. The cantonal migration office that issued it holds the file. When your employee settles elsewhere, the file passes to the office of the new canton. The permit category does not change merely because the address does.
The practical consequences differ by category:
- Permit B (residence): the permit is tied to the canton of residence. A move is reported, and the new canton registers the holder. See Permit B.
- Permit L (short stay): short-term permits are tied to a specific purpose and place. A change of canton is treated with more caution, and the new office decides how to proceed. See Permit L.
- Accompanying family: spouses and children follow the main holder. See permits for spouses and children.
- Self-employed and founders: conditions attached to the activity may need a fresh look. See self-employed permits.
The exact conditions for each category, including what a canton may refuse, are not set out here. The receiving cantonal office confirms them for the individual file.
The order of events
An orderly canton change follows a sequence. The employer or its mobility provider can map it before the date of the move.
- Confirm the reason for the move and the intended date with your employee.
- Check whether the employment contract, workplace or assignment letter changes.
- Notify the commune (Gemeinde) of departure and register in the new commune.
- Allow the cantonal migration office to process the transfer of the permit file.
- Update payroll for the correct tax canton.
- Update insurance records and check the provider's rules.
Some of these steps run in parallel. Others depend on a decision by an authority, and the employer cannot speed them up. A tool such as the permit finder helps clarify the category; the relocation calendar helps place the dates.
What the employer coordinates
The employer rarely files the personal notifications itself, but it often supports them. A clear internal owner avoids gaps.
Immigration
Most cantons expect a change of address to be reported to the commune of departure and registered in the commune of arrival. The migration office then updates the permit record. Processing times, required forms and fees vary by canton. The office of the new canton will say what it needs.
Where the move changes the place of work, the new canton may also look again at the labour-market conditions of the permit. For the general route, see how to get a Swiss work permit. Where quotas are involved for third-country nationals, the quota overview explains how they work.
Payroll and withholding tax
Foreign nationals without a permit C or an establishment permit are taxed at source: the employer deducts the tax and pays it monthly to the canton. For permit B or L holders with income below CHF 120,000, withholding tax is in principle final, with a later ordinary assessment available on request. From CHF 120,000 a later ordinary assessment is compulsory (FTA, ESTV). The cantonal withholding tax guidance sets out the detail.
A change of canton can change which canton receives the tax and which tariff applies. The date from which the new canton is responsible depends on the rules of the cantons involved. Payroll teams therefore need the exact date of residence change and the confirmation from the commune. More on this is in payroll and social security for assignees and tax returns in Switzerland.
Insurance
Basic health insurance is compulsory for residents. Premiums are set by canton and region, so a change of canton can change the premium for the same cover. The insurer needs the new address, and the insurer's own rules decide whether and when the premium is adjusted. Models and deductibles are explained in deductibles and insurance models and health insurance for expatriate employees.
Accident cover for employees is arranged through the employer. The employer's insurer needs the updated address. Cases that depend on the policy wording go to the provider or to a specialist.
Employer responsibilities at a glance
| Area | Who acts | What the employer typically handles |
|---|---|---|
| Residence registration | Employee, commune | Provides supporting documents and dates |
| Permit file | Cantonal migration office | Supplies employment details when asked |
| Withholding tax | Employer, canton | Updates the payroll tax canton and tariff |
| Health insurance | Employee, insurer | Informs policy owners and benefit administrators |
| Housing | Employee | Supports the search under the policy |
Planning from abroad
If the move is planned while the transferee is still abroad, the better question is often where to settle first. A difference between cantons in taxes, schools and permit handling can be reviewed before arrival, using the city comparator and the school choice guide. Moving later within Switzerland is possible, but each change repeats part of the process described above. Policies from Germany, France or the United States differ on tax equalisation and allowances, so the home-country policy is read alongside the Swiss rules.
Checklist for the HR or mobility owner
- Record the date the employee leaves the current commune
- Obtain proof of registration in the new commune
- Confirm that the migration office of the new canton has received the permit file
- Update the payroll tax canton and the withholding tax tariff
- Send the new address to the health and accident insurers
- Review the housing and settling-in support in the policy
- Note any effect on spouse or children permits and schooling

Frequently asked questions
Does a change of canton cancel the permit?
No. The permit stays valid in principle, but the file passes to the migration office of the new canton. That office confirms how the transfer is recorded for the individual holder.
Who notifies the authorities of a canton change?
The employee normally reports the departure and registers in the new commune. The employer often supports this with documents. The migration office then updates the permit record.
Does the employer need to be told before the move?
It is sensible practice for the policy to require advance notice. Payroll, insurance and immigration steps all depend on the date of the move.
Is a new work permit needed after a change of canton?
Not necessarily. Where only the residence changes, the existing permit is usually transferred. Where the workplace or employer changes, the new canton may review the conditions.
Is the process the same for permit B and permit L?
Not exactly. Permit B is tied to residence in the canton. Permit L is linked to a purpose and a place, so the new office decides how a move is handled.
Can an assignee on a short-term permit change canton freely?
Not in every case. The conditions depend on the permit and the canton. The office of the receiving canton can say whether the move is accepted.
What happens to accompanying family permits?
Family permits follow the main holder, and the migration office updates them with the file. Schooling and childcare are arranged locally. See family reunification.
Does withholding tax change after the move?
It can. The canton of residence determines which canton receives the tax and which tariff applies. The date from which the new canton is responsible depends on the cantonal rules.
Who pays withholding tax: employer or employee?
The employer deducts the tax from salary and pays it to the canton, usually monthly. The employee bears the cost economically, unless the policy provides for a tax equalisation arrangement.
Is withholding tax final?
For permit B or L holders with income below CHF 120,000, it is in principle final, with a later ordinary assessment available on request. From CHF 120,000 an ordinary assessment follows (FTA, ESTV).
What if the assignee holds a permit C?
Permit C holders are not taxed at source in the same way. They are assessed through an ordinary tax return, and the canton of residence is the relevant tax authority.
Do cantons apply the same tax rates?
No. Cantons and communes set their own rates, so the same salary can produce a different tax result in another canton. This is a reason to review the tax position before a move.
Does health insurance have to be changed?
Not necessarily. The same insurer can usually continue. The address is updated, and premiums can differ by canton and region according to the insurer's rules.
Is the premium different in another canton?
Often yes. Premiums for basic cover are regional. The insurer states the amount that applies to the new address.
Who informs the accident insurer?
The employer arranges accident cover for employees, so the employer or its payroll team passes on the new address. The policy terms describe what else is needed.
Can the move affect the school place of a child?
Yes. Public schooling is organised by commune and canton, and a change of residence can change the school. See the school choice guide.
Does a canton change affect the end-of-assignment procedure?
The departure from Switzerland is reported to the commune of residence at that time. See end of assignment for the steps.
Can the employer arrange the move for the employee?
The employer can fund and coordinate housing and settling-in support, depending on the policy. Personal notifications remain with the employee and the authorities.
What documents are usually requested?
Typically the permit, passport, employment contract, proof of the new address and the deregistration certificate from the previous commune. The authority of the receiving canton lists its requirements.
Where can the specifics be checked?
Cantonal migration offices and tax administrations publish their own guidance. For a case involving several authorities, a specialist reviews the facts via the request at the bottom of the page.
