Non-resident owner of a Swiss rental: filing, the rate trap and what you can deduct

Most owners meet this question at the wrong moment: after a season that disappointed, holding a contract signed three years earlier and never re-read. The reassuring part is that Swiss law gives the owner the right to leave. The expensive part is not that right — it is the timing, and the clauses that keep working after the contract ends.

This guide covers what a management mandate actually is in Swiss law, the five clauses that decide what an exit costs, how notice works in practice for short-term rentals in the Montreux–Lausanne corridor, and what a clean handover looks like. It is the counterpart to our market guides: those tell you what an apartment should earn; this one is for the moment the numbers are not arriving.

Living abroad does not switch off the Swiss tax system. What is taxed is the apartment, and the canton where it stands keeps a file on it — the rent it produces, and in most cantons its value — for as long as you own it, whatever your address in Paris, London or Dubai.

For an owner who lets furnished, and short-term in particular, that means a cantonal declaration every year, a communal tourist-tax file every month, and a result computed on the Swiss property alone. Here is how those three fit together.

You are taxed where the apartment is, not where you live

Swiss tax law works on connecting factors. If you are neither domiciled nor resident in Switzerland, you are taxable here only on the elements that have a Swiss link — and property is the oldest of them. In Vaud the cantonal law is explicit: a person who is neither domiciled nor resident in the canton is still taxable on the strength of a property they own there (rattachement économique, art. 4 LI). Owning the apartment is enough. You do not need a company, a business or a residency permit.

In practice the file opens itself. The land register is public, the commune knows the apartment, and the cantonal administration registers you, issues a return and expects an answer every year. You declare the rent and the related charges — not your worldwide income — but you declare them in Switzerland, in the canton of the property.

The double-tax treaty protects you from being taxed twice, not from being taxed properly: Swiss real estate is allocated to Switzerland, and your country of residence either exempts the income or grants a credit for the Swiss tax. That is why an apartment in Montreux can be almost invisible on your French or British return and still be a full line item in Lausanne.

What is deductible — and how far it goes

Deductions are computed against the Swiss property, and inside that box they are broad: mortgage interest actually paid, maintenance and repairs, building insurance, the property tax itself, and the commission you pay an operator. On the revenue side, the platform fee is a cost rather than a reduction of income — the cleanest file shows the gross rent and claims the commission as a deduction.

Line	Swiss rental file
Revenue	Gross rent, plus any cleaning or service fee charged to guests
Deductible	Mortgage interest, maintenance, building insurance, management commission, property tax
Pass-through	Tourist tax collected from guests and remitted to the commune — never your income, but it has to reconcile
Not deductible here	Personal charges, interest on a mortgage secured on your home abroad, deficits from other activities
Wealth tax	The fiscal value of the apartment at the cantonal valuation — not the market price

What stays out of the box matters just as much. Interest on your own home, personal insurance, family charges and any loss made elsewhere do not lower the Swiss taxable amount: the result is computed in isolation, which can turn a break-even year on paper into a taxable year here.

Keep the paper, because a file reviewed at a distance is won on documents: the mortgage interest statement, the invoices, the operator’s annual statement and the tourist-tax reconciliation. Three of those four arrive from third parties — ask for them in January, not in November.

Short-term letting adds a communal file to the tax file

A furnished short-term rental is an activity in the eyes of the commune, and the commune is where the obligations start. The tourist tax, charged per guest and per night at the rate the municipality sets, is collected by you and remitted on its own schedule, and the guest register or host-announcement duty applies on top. In Montreux that file is monthly, and its totals have to match what you declare in Lausanne.

VAT is the second threshold to watch. Below the federal registration threshold the apartment remains a private asset producing rental income; cross it and you register, invoice the accommodation at the reduced rate and recover input VAT on the costs. Whether you get there depends on turnover, on the length of the stays and on how the contract is built — and it is the point where professional management starts paying for itself in accounting discipline alone. Swiss tax and VAT on a short-term rental: what the owner actually pays goes through those mechanics line by line.

None of this replaces the commune’s own rules. Night caps, authorisation and the question of whether the apartment may be let furnished at all are decided locally, not federally — verify the regime of the municipality before you build a revenue plan on a full calendar.

For the rest of the owner-side file — registration, night caps, mandates and revenue — start from the owner guides hub.

The day you sell, the canton collects first

Cantonal real-estate capital gains tax is owed by the seller, and living abroad does not exempt you from it: the gain on a Montreux apartment is Vaud’s business whatever the seller’s residency. Because the administration has no other way to secure its claim on a non-resident, expect the estimated gains tax to be sequestered at the deed by the notary, and expect to be asked for a delivery address in Switzerland for the file.

Read that in advance, with the purchase file: the acquisition costs, the invoiced works that add to the invested value and the length of ownership all move the number. A documented decade of invoices is worth more at the notary’s office than at any appeal.

The owner’s calendar

• Every month: collect and remit the tourist tax, and reconcile the platform payouts with the bookings they represent.
• Every quarter, if you are VAT-registered: file and pay, and claim the input VAT on maintenance and utilities.
• Once a year: the cantonal return, built on the operator’s annual statement, the mortgage interest certificate and the invoices.
• When you sell: gains tax, sequester at the deed, and a Swiss address on file for the tax administration.
