A rent deposit in Switzerland (Mietzinsdepot or Mietkaution) is the security a landlord asks for before a tenant moves in. For a transferee who is still abroad, it is often the first practical obstacle in the housing process. The money must be arranged before arrival, usually before your employee has a Swiss bank account.
This page explains how the deposit works, the three usual ways to provide it, and the decisions that fall to the employer. It is written for the HR or mobility manager who sets the policy, not for the tenant who has already arrived.
What the deposit is for
The deposit protects the landlord against unpaid rent and damage beyond normal wear. It is not a payment to the landlord. It remains the tenant's money and is returned at the end of the lease if no valid claim is made.
Swiss tenancy law limits how much a landlord may ask for and requires the money to be kept apart from the landlord's own funds. The lease should state the amount and the way it is held. A specialist can confirm the limit that applies to your employee's lease. Do not rely on a figure quoted informally by an agent or a previous tenant.
Three terms appear in almost every Swiss lease file:
- Mietzinsdepot / Mietkaution: the rent deposit itself.
- Sperrkonto: the blocked account in which a cash deposit is held.
- Mietkautionsversicherung: a deposit guarantee, sold as an insurance-type product, that replaces the cash.
The decision tree for your policy
Your transferee reaches one of three solutions. The choice depends on cash flow, timing and who is willing to carry the cost.
Option one: the blocked account
The classic solution. A bank opens an account in the tenant's name, and the tenant pays the deposit into it. The account is blocked: neither side can withdraw without the other's agreement, or without a final court or authority decision. The landlord receives written confirmation that the funds are in place.
Advantages for the employer:
- The money stays the employee's property, with interest where the bank pays any.
- Landlords and property managers (régies, Verwaltungen) know the format and accept it readily.
- The cost of the product is low compared with a guarantee.
The difficulty is timing. A bank may need identification documents, proof of address and sometimes a residence permit before it will open an account for someone who has not yet arrived. Your employee may also have no Swiss account from which to pay. Plan this step early. See the rental application file for the documents a landlord expects at the same stage.
Option two: the deposit guarantee
A deposit guarantee replaces the cash with a commitment from a provider to pay the landlord if a valid claim arises. The tenant pays an annual premium instead of tying up the capital.
This suits a transferee who does not want to move a large sum before arrival, or an employer who would rather not advance cash. Points to check:
- The landlord must agree to accept a guarantee. Not every landlord does, and some state in the advertisement that cash only is accepted.
- The premium is a cost that is not returned at the end of the lease. Your policy should say whether the company or the employee bears it.
- The provider will assess the tenant. Someone with no Swiss credit history may be asked for documents or refused. Ask what the provider needs from a person who has just arrived.
- If the guarantee is called on, the provider usually recovers the sum from the tenant. The employee remains liable.
Option three: the employer arrangement
Some employers take on part of the burden. This can be done in several ways, and each has different legal and tax consequences:
- Advance to the employee: the company lends the deposit amount, repaid through payroll over an agreed period.
- Company-funded deposit: the company pays the deposit as part of the relocation package. Whether the amount is treated as a benefit in kind depends on the structure and the canton, and a tax specialist should confirm the treatment.
- Employer as tenant: the company signs the lease and sub-lets to the employee, or acts as co-signatory. This is common for short assignments and furnished apartments, but it ties the company to the lease terms.
- Guarantee by the employer: a letter or contractual undertaking given to the landlord. Many landlords accept this from a large, well-known employer; others do not.
Decide in the policy which of these you offer, who approves exceptions and how the money is recovered if the employee leaves early. Do not leave it to the transferee to improvise. For the wider cost picture, see employee relocation costs to Switzerland.
Comparing the three options
Where the deposit fits in the relocation timeline
The deposit is one step in a longer chain. A landlord will not hand over keys until the deposit is confirmed, and the lease is usually signed only when the rental file is complete. If your employee is applying from abroad, the work should start well before the move date.
A sensible order for a transferee arriving from outside Switzerland:
- Confirm the immigration route. Nationals of the EU and EFTA follow one regime and nationals of other countries follow another (see the SEM admission rules and the permit finder). Many landlords want proof of the work contract or permit before they sign.
- Prepare the rental file, including identification, employment letter and, where relevant, the policy's confirmation of who pays the deposit.
- Choose the deposit form and start the application with the bank or guarantor.
- Sign the lease and complete the deposit.
- Take the keys at the handover inspection (see moving in and out).
- Register with the municipality within 14 days of arrival (FOPH and municipal sources; the exact rule varies by canton and municipality). Documents typically include identification, the residence or work permit and proof of health insurance.
- Take out basic health insurance within three months of taking up residence (FOPH). Cover then runs back to the date of residence if the deadline is met.
The registration step matters for the deposit. Some banks ask for a municipal registration certificate before they will open a normal account, and some landlords ask for it before releasing the deposit to a new tenant's account. Check the order of steps with the property manager and the bank.
Problems that occur in practice
The tenant cannot open the account in time
This is the most common problem. A bank may refuse an application from someone without a permit, or take several weeks. Ask the bank in advance which documents it requires from a non-resident, and have a second route ready, such as a guarantee or an employer undertaking.
The landlord will not accept the chosen form
Some landlords refuse guarantees; others refuse employer letters. Ask the property manager early what is accepted. Write it into the rental file checklist, and use the rental file checker before submission.
The amount is higher than the budget
Deposits are tied to the rent, so a higher rent means a larger sum to immobilise. If your policy covers the deposit, make sure the budget is set with the likely rents in mind. The rent cost guide gives the background.
Disputes at the end of the lease
The deposit is released when both sides agree, or when a decision is made. Damage claims are the usual cause of delay. A careful handover report on arrival is the best protection. Insist that your employee attends the inspection and keeps a copy of the report.
Early departure
If an assignment ends early, the lease may not. Notice periods and relet arrangements depend on the contract. Your policy should say what happens to the deposit, whether the company recovers any advance, and who handles the exit inspection.
A short checklist for HR teams
- State in the policy whether the company advances, funds or guarantees the deposit.
- Decide who pays the guarantee premium, if one is used.
- Ask a tax specialist how any company-funded deposit is treated.
- Brief the transferee on which documents the bank or guarantor needs.
- Ask the property manager which forms of deposit the landlord accepts.
- Keep a copy of the deposit confirmation and the handover report.
- Record how and when any advance is repaid.

Frequently asked questions
What is a rent deposit in Switzerland?
It is a security sum the tenant provides before moving in. It protects the landlord against unpaid rent and damage. It stays the tenant's money and is returned at the end of the lease if there is no valid claim.
Is the deposit paid to the landlord?
No. In the usual form it is paid into a blocked account in the tenant's name. The landlord cannot take the money without the tenant's agreement or a decision of the competent body.
What does Mietzinsdepot mean?
Mietzinsdepot is the German term for the rent deposit account. You will also see Mietkaution and, in French-speaking areas, garantie de loyer. In a lease they refer to the same security.
How much is the deposit?
The lease states the amount. Swiss tenancy law limits it, and the limit can be confirmed by a specialist for the lease in question. Do not assume that an informal figure applies.
Can my employee pay the deposit from abroad?
Often yes, but it depends on the bank. Some banks need the tenant in person or require a permit, so ask early. A guarantee or an employer arrangement may be simpler for someone who has not yet arrived.
What is a blocked account?
A Sperrkonto is a bank account in the tenant's name that neither side can empty alone. The landlord receives written confirmation that the funds are held.
What is a deposit guarantee?
It is a product that replaces the cash. A provider commits to pay the landlord if a valid claim arises, and the tenant pays a premium. The premium is not refunded.
Does every landlord accept a deposit guarantee?
No. Some accept only cash in a blocked account. Ask the property manager before applying, and note the answer in the rental file.
Who should pay the guarantee premium?
This is a policy decision. Some employers cover it as part of the relocation package; others leave it to the employee. State it clearly in the policy to avoid disputes.
Can the employer pay the deposit?
Yes. The company can advance the sum, fund it or give an undertaking to the landlord. Each route has different tax and legal effects, so a specialist should review the structure.
Is a company-paid deposit taxable for the employee?
It may be, depending on how it is structured and on the canton. The treatment of a loan, a gift and a returnable deposit differs. Ask a tax adviser before the policy is finalised.
Can the company sign the lease instead?
It can, and this is common for short assignments and furnished housing. The company then takes on the tenant's obligations. See temporary and furnished housing for the typical set-up.
What if my employee cannot open a Swiss bank account?
Use another route. A guarantee, an employer undertaking or a company-held lease can replace the account. Ask the property manager which of these the landlord accepts.
Does the deposit need to be paid before the keys are handed over?
In practice, yes. The landlord normally wants confirmation of the deposit before releasing the keys. Plan the deposit and the handover date together.
When is the deposit returned?
At the end of the lease, once both sides agree or a decision is made. The release can be delayed by damage claims or by disagreement on the final inspection.
What happens if the landlord claims damage?
The landlord must justify the claim. A careful handover report from the start of the lease is the best evidence of the state of the property. Normal wear is not the tenant's responsibility.
Does the deposit earn interest?
In a blocked account, interest may accrue and belongs to the tenant, depending on the bank's terms. Check the terms when the account is opened.
Do EU and non-EU transferees follow different rules for the deposit?
The deposit rules are the same, but the immigration route differs. EU and EFTA nationals follow one regime and third-country nationals another (SEM). That affects timing, and therefore when documents are available for the bank and landlord. See the permit finder.
When must my employee register with the municipality?
Within 14 days of arrival, though the rule varies by canton and municipality (ch.ch). Identification, the permit and proof of health insurance are typically requested.
When must basic health insurance start?
Within three months of taking up residence (FOPH). If the deadline is met, cover runs back to the date of residence. See Swiss health insurance for expatriate employees.
Can my employee rent without a permit?
Some landlords will sign only when a permit or work contract is shown. Others accept a signed employment contract. The practice varies, and the property manager will say what is needed.
What if the assignment ends before the lease?
The lease continues unless it is ended according to its terms. The policy should say who handles notice, relet and the deposit. A specialist can review the lease for early exit options.
Does the deposit matter if the employee buys a home later?
Not directly. The deposit is returned at the end of the rental. Buying property by someone from abroad follows separate rules, covered in buying property in Switzerland.
