Swiss Buyer’s Property Guide

Section 01

Free Movement, Non-EU Taxation

Switzerland sits outside the EU and the EEA but has concluded an agreement with the EU on the free movement of persons. In practical terms this gives Swiss nationals rights to enter, reside and work in Spain that are broadly comparable to those of EU citizens. You are not subject to the 90/180-day limit that constrains British and American visitors, and you do not need a visa to buy or to live here.

Spanish tax law, however, draws its line at EU and EEA membership, not at free movement. For non-resident property taxation, Swiss residents fall on the non-EU side alongside British and American owners.

Why this matters in money terms

Spain taxes non-resident rental income at one rate for EU and EEA residents and a higher rate for everyone else. More significantly, EU and EEA residents may deduct allowable expenses — mortgage interest, community fees, insurance, maintenance, depreciation — before the tax is calculated. Non-EU owners cannot deduct anything. Tax is charged on gross rent.

On a property with a mortgage and meaningful running costs, the combination of a higher rate and no deductions can produce an effective tax burden several times that of an identical property owned by a French or German neighbour. If letting forms any part of your case, this deserves modelling properly before you choose a property, not after.

Section 02

Why Swiss Buyers Choose Catalonia

Catalonia offers Swiss buyers something the Alpine second-home market largely cannot: sea, a long season, and a major international city, all within a short flight. Zurich, Geneva and Basel all connect frequently to Barcelona, with flight times of under two hours.

There is also a value consideration. Swiss buyers accustomed to domestic prices — and to the restrictions the Lex Koller places on foreign buyers at home — generally find Catalan property markedly better value for the space, land and sea frontage involved, and the Spanish market entirely open to them.

Where Swiss buyers concentrate

• Sitges — year-round infrastructure, an established international community and 25 minutes to El Prat.
• Costa Brava — Begur, Llafranc, Aiguablava and S’Agaró for privacy and sea frontage at the upper end.
• Barcelona — Sarrià-Sant Gervasi and Pedralbes for buyers wanting a city base rather than a coastal one.
• The Empordà — masías and estates for buyers prioritising land, discretion and architectural substance.

Section 03

The Spanish Process

Swiss buyers are used to a notarial system and to a well-ordered land register, so the shape of the Spanish transaction is familiar. The divergence is in what the notary does. The Spanish notario confirms identity and capacity and formalises the escritura, but does not investigate debts, planning conformity, boundaries or whether what is physically built matches what is registered. That work belongs to a lawyer you appoint.

The sequence

Section 04

Tax: Switzerland and Spain

Switzerland and Spain have a double taxation treaty, revised in the last fifteen years to include exchange of information. Income from Spanish property is generally taxable in Spain, with Switzerland applying relief. The treaty determines allocation; it does not change the rate Spain applies, which is where the non-EU position bites.

Swiss wealth tax and foreign property

Switzerland levies wealth tax at cantonal and communal level. Foreign real estate is generally exempt from Swiss wealth tax under treaty relief, but it is typically taken into account when determining the rate applied to your remaining taxable wealth. The property therefore usually influences your Swiss position even where it is not itself taxed there. The same principle commonly applies to foreign property income and the rate on your other income.

Spanish wealth tax as well

Separately, Spain levies wealth tax on Spanish assets held by non-residents, with Catalonia applying its own scale, alongside a national-level charge aimed at larger fortunes. For purchases at the upper end of the Catalan market this is a genuine recurring cost and should be modelled before purchase rather than discovered afterwards.

Inheritance

Spanish inheritance and gift tax is regionally administered, so Catalan rules and reliefs govern Catalan property. Separately, the EU succession regulation determines which country’s succession law applies to your estate, and Catalonia has its own succession code distinct from the rest of Spain. A Spanish will covering your Spanish assets, drafted to operate alongside your Swiss arrangements, is the usual and inexpensive solution.

Section 05

Practicalities

Currency

Unlike EU buyers you carry genuine exchange exposure, and not only on the purchase. Community fees, the annual IBI, utilities, maintenance and any euro mortgage are all ongoing euro costs funded from Swiss francs. On a purchase of any size the difference between a bank’s retail exchange rate and a specialist currency service is material, and worth arranging before you need to move funds rather than at completion.

Financing

Spanish banks lend to non-residents, typically at lower loan-to-value ratios than to residents. Swiss buyers frequently have alternatives — borrowing against Swiss assets or securities — which may price better. The choice is not purely about rate: because Spanish non-EU owners cannot deduct mortgage interest against rental income, borrowing does not carry the tax efficiency here that it would for an EU owner. That asymmetry should feed into the decision.

Getting there

• Zurich, Geneva and Basel all connect frequently to Barcelona, with flight times under two hours.
• Girona is served seasonally and is the closer arrival for the northern Costa Brava.
• Driving is around 1,000 km from Zurich, comfortable in a day with a stop.

Letting your property

Given the non-EU tax treatment of rental income, letting is often less attractive for Swiss owners than for their EU neighbours — worth modelling honestly before you buy a property chosen for its rental case. If you do intend to let, a valid transferable tourist licence is required: Barcelona has moved to phase out licences and coastal towns including Sitges operate strict quotas.

Section 06

Why Independent Representation Matters

At the upper end of the Catalan market, the problems that cost money are rarely obvious ones. They are unregistered extensions on a property that has changed hands twice without anyone checking; a coastal-law constraint that limits what can be rebuilt; a tourist licence assumed rather than verified; a price anchored to what a previous foreign buyer paid rather than to the local market.

None of these are things a seller’s agent is incentivised to raise, and almost every agent in Catalonia holds a seller mandate, is paid by the seller and owes their duty to the seller. For Swiss buyers, whose non-EU tax position already narrows the margin for error, the cost of unverified assumptions is higher than for an EU buyer making the same mistake.

We act for buyers only and never hold a seller mandate. We search across portals, agency inventory and off-market stock, verify registration, coastal constraints and licence status, negotiate against the listing agent, and carry the legal conveyancing through to registration of your title — for a flat €3,000, whatever the purchase price. On a purchase at this level, that fee is a rounding error against a single missed check.
