Switzerland restricts what foreigners can buy at home through the Lex Koller; Spain does the opposite and places no restriction on Swiss buyers at all. That asymmetry, plus roughly two-hour flights from Zurich and Geneva to Barcelona, explains why Sitges keeps appearing on Swiss shortlists. The purchase process is identical for a Swiss buyer and an EU buyer. The tax position is not: Switzerland sits outside the EU and EEA, so Swiss residents pay Spanish non-resident income tax at 24% on gross rental income with no deductions, rather than the 19% on net income that EU owners enjoy. This guide sets out that difference in francs-and-euros terms, the Swiss side of the tax picture, and the practical steps — NIE, financing, currency — of buying in Sitges from Switzerland, as matters stand in July 2026.
Why Sitges keeps appearing on Swiss shortlists
Barcelona El Prat is around 35 minutes from Sitges by car or train, and the Swiss connections are dense. SWISS and Vueling fly non-stop from Zurich, and easyJet and Vueling from Geneva, with multiple departures a day on both routes through summer 2026. Scheduled flight time is about 1 hour 50 minutes, which makes a Friday-evening arrival at the beach house entirely routine.
There is also a legal asymmetry worth naming. At home, the Lex Koller caps sales of holiday homes to non-resident foreigners at a national quota of 1,500 authorisations a year, allocated unevenly across the cantons. Spain imposes nothing comparable. A Swiss buyer purchases in Sitges under the same rules as a Spanish national: no permit, no quota, no plot-size or floor-area limits — just an NIE and, in practice, a Spanish bank account.
Value completes the picture. Prime Sitges trades at a fraction of comparable lakeside stock around Zurich, Geneva or Zug on a per-square-metre basis, in a town with genuine year-round life, an international school and around 300 days of sunshine. Swiss citizens visit visa-free under Schengen rules for up to 90 days in any 180-day period.
The key tax difference: Switzerland is outside the EU and EEA
Spanish non-resident income tax (IRNR) draws a hard line at the EU/EEA border. Residents of an EU or EEA state pay 19% on net rental income, deducting IBI, community fees, insurance, repairs, mortgage interest and depreciation in proportion to the days let. Residents of anywhere else — Switzerland included — pay 24% on gross rental income with no deductions at all. The rule attaches to where you are tax resident, not to your passport: a German national living in Zurich is on the 24% gross regime, while a Swiss national living in Munich is on the 19% net regime.
Worked through, the gap is substantial. Take an apartment producing €24,000.00 of gross annual rent with €9,000.00 of legitimate annual costs. An owner resident in the EU deducts the costs and pays 19% on €15,000.00, which is €2,850.00. An owner resident in Switzerland pays 24% on the full €24,000.00, which is €5,760.00 — €2,910.00 more each year on an identical property, roughly double the tax bill. Rental income is declared annually on Modelo 210, filed between 1 and 20 January for the previous year.
The same 24%-versus-19% split applies to imputed income, the notional charge for periods when the property sits empty for your own use: 1.1% of cadastral value (2% where the value has not been recently revised) becomes the taxable base. On a €150,000.00 cadastral value, that is €396.00 a year for a Swiss owner against €313.50 for an EU owner. Capital gains on a future sale, by contrast, are taxed at 19% for all non-residents alike.
The 28 July 2025 court ruling — a door ajar, not open
On 28 July 2025 the Audiencia Nacional, Spain's National High Court, ruled (appeal no. 636/2021) in a case brought by a United States resident that denying expense deductions to non-EU/EEA landlords breaches the free movement of capital under Article 63 TFEU — a freedom that protects third countries such as Switzerland as well as EU member states.
This is not yet settled practice. The tax agency continues to apply the 24% gross basis, and the State's legal service has lodged an appeal against the ruling before the Tribunal Supremo. Many advisers currently recommend filing on the gross basis while lodging rectification claims for open years, so a refund can be recovered if the case law consolidates. Take professional advice before filing on a net basis as a Swiss resident; do not simply copy the EU treatment.
Francs, euros and financing
Your budget is in francs; the purchase completes in euros. A move of a few centimes in CHF/EUR between reservation and completion — typically eight to twelve weeks — can shift the cost of an €800,000.00 purchase by tens of thousands of francs in either direction. Specialist currency brokers usually beat retail bank spreads by a clear margin, and a forward contract lets you lock the rate on the day you sign the arras (reservation) contract. Our guide to [Transferring Money to Spain for a Property Purchase](/guides/transferring-money-to-spain-property) covers the mechanics.
Spanish banks lend to non-residents at typically 60% to 70% of the bank's valuation, though some lenders apply more conservative 50% to 60% caps to non-EU applicants, Swiss residents included. Swiss salary certificates and tax returns are accepted as income evidence, and fixed rates quoted to non-residents sat at around 2.8% to 3.5% in early 2026.
Swiss banks will not normally take Spanish property as collateral, but raising funds against Swiss assets — extending an existing Swiss mortgage or pledging a portfolio — is often cheaper than a Spanish loan. Compare the after-tax cost carefully: Swiss tax rules allocate debt and interest proportionally across your worldwide assets, so where the borrowing sits changes the calculation in both countries.
Two wealth taxes and a 1966 treaty
On the Swiss side, every canton levies wealth tax, but foreign real estate is exempt: your Sitges home is declared at its tax value and used only to set the rate applied to your Swiss-taxable wealth (exemption with progression). Income is treated the same way — the imputed rental value (Eigenmietwert) of a foreign home is declared but exempt with progression. Swiss voters approved the abolition of the imputed rental value in the 28 September 2025 federal vote, and the Federal Council has since set the change to take effect on 1 January 2029.
On the Spanish side, non-residents pay Spanish wealth tax on Spanish-situs assets above a state exemption of €700,000.00 per person — a couple buying 50/50 shields €1,400,000.00. Since Law 11/2021, non-residents may instead elect the rules of the region where their assets sit, whatever their country of residence, but Catalonia's general allowance is €500,000.00, so most Swiss owners are better served by the state rules. The separate state solidarity tax applies above €3,000,000.00 of Spanish net wealth.
The double taxation agreement of 26 April 1966, amended most recently by the protocol of 27 July 2011, allocates taxing rights cleanly: Spain may tax income, gains and capital connected to Spanish real estate, and Switzerland relieves double taxation by exemption with progression. You will not pay twice, but the property nudges up the rate on your remaining Swiss income and wealth. One caution: if you are taxed on an expenditure basis (forfait fiscal) in Switzerland, the treaty interaction has particular conditions — take specific advice before structuring the purchase.
Practical steps: NIE, purchase costs and residence
The NIE, Spain's foreigner identification number, can be requested from Switzerland through the Spanish consular network — Bern, Geneva or Zurich, depending on your canton of residence — with the certificate typically issued within two to four weeks. Faster in practice: grant power of attorney to a Spanish lawyer, signed before a Swiss notary with an apostille, and the NIE, bank account and completion can all be handled without repeated trips.
On costs, resale property in Catalonia pays transfer tax (ITP), progressive since 27 June 2025 under Decree Law 5/2025: 10% up to €600,000.00, 11% to €900,000.00, 12% to €1,500,000.00 and 13% above that, applied in tiers. An €800,000.00 resale purchase therefore carries €82,000.00 of ITP, an average of 10.25%. New builds pay 10% IVA plus stamp duty instead. With notary, registry and legal fees on top, budget roughly 11% to 13% above the purchase price.
One thing a purchase does not buy is residency: Spain's golden visa ended on 3 April 2025, and ownership changes nothing about your immigration position. Swiss citizens are, however, better placed than most non-EU buyers. Under the 1999 EU–Swiss Agreement on the Free Movement of Persons you can visit for 90 days in any 180 and, if you decide to move, register as a resident in Spain much as an EU citizen would — showing sufficient means and health cover, with no non-lucrative or digital nomad visa required. Registering as a resident normally makes you a Spanish tax resident, a shift worth modelling carefully before you commit.

Frequently asked questions
Are there any restrictions on Swiss residents buying property in Spain?
No. Spain has no equivalent of the Lex Koller. Swiss buyers purchase under the same rules as Spanish nationals: an NIE, a Spanish bank account and standard due diligence. There are no quotas, permits or minimum-stay conditions attached to ownership.
Will I pay Swiss tax on a home I own in Sitges?
Not directly. Swiss cantonal wealth tax exempts foreign real estate but counts it when setting your rate, and the imputed rental value is treated the same way (exemption with progression). You must still declare the property in your Swiss return. The abolition of the imputed rental value, approved in the September 2025 federal vote, takes effect on 1 January 2029.
Can I deduct expenses from my Sitges rental income as a Swiss resident?
Under current practice, no: as a non-EU/EEA resident you pay 24% on gross rent through Modelo 210. The Audiencia Nacional ruled on 28 July 2025 that this breaches the free movement of capital, but the ruling has been appealed to the Supreme Court and the tax agency continues to apply the gross basis. Many advisers file gross and lodge rectification claims to keep past years open; take advice before filing net.
How much can I borrow from a Spanish bank as a Swiss resident?
Non-residents typically obtain 60% to 70% of the bank valuation, though some lenders cap non-EU applicants, Swiss residents included, at 50% to 60%. Swiss salary certificates and tax returns are accepted as income evidence, and fixed rates quoted to non-residents were around 2.8% to 3.5% in early 2026.
Does buying in Sitges give me Spanish residency?
No. Spain's golden visa ended on 3 April 2025 and no property purchase confers residency. Swiss citizens can stay visa-free for up to 90 days in any 180-day period, and under the EU–Swiss free movement agreement they can move to Spain by registering as residents with sufficient means and health insurance, without needing a visa. Becoming resident normally makes you a Spanish tax resident.
