Mortgage for cross-border workers (G permit)

Every day, over 400,000 cross-border workers ("frontaliers") cross the border to work in Switzerland. If you are one of them and wish to purchase property on Swiss territory, know that it is entirely possible -- but with more demanding conditions than for a resident. This guide details the rules, constraints, and strategies for successfully completing your mortgage project as a cross-border worker.

What is a cross-border worker?

A cross-border worker (frontalier) is a person who resides in a country bordering Switzerland -- France, Germany, Italy, or Austria -- and crosses the border daily or weekly to work in Switzerland. This status is formalized by the G permit, a specific residence title issued by Swiss authorities.

The G permit is granted to EU/EFTA nationals who can demonstrate an employment contract in Switzerland and a residence in the border zone of their country. It is renewable every 5 years (or annually for fixed-term contracts). The holder must in principle return to their foreign residence at least once a week.

Main border zones

In French-speaking Switzerland, the vast majority of cross-border workers reside in France, primarily in Haute-Savoie (74) and Ain (01) departments for Geneva, and in Doubs (25) and French Jura for the cantons of Neuchatel and Jura. In German-speaking Switzerland, many cross-border workers come from Germany (Baden-Wuerttemberg) and Austria (Vorarlberg). Ticino hosts cross-border workers from Italy (Lombardy, Piedmont).

The legal framework: Lex Koller and the G permit

Property acquisition by cross-border workers in Switzerland is governed by the Lex Koller (Federal Act on the Acquisition of Real Estate by Persons Abroad). As a non-resident, the cross-border worker is considered a "person abroad" under this law, which implies specific restrictions.

Acquisition conditions for cross-border workers

• Border zone only: The property must be located in the border zone of the worker's place of employment, as defined by bilateral agreements between Switzerland and neighboring countries
• Primary residence mandatory: Only the purchase of a primary residence is authorized -- no secondary residence or rental investment property
• Cantonal authorization: An acquisition authorization must be obtained from the competent cantonal authority
• Actual occupancy: The cross-border worker must actually live in the purchased property

It is important to note that cantons have some interpretive latitude. Some cantons, such as Geneva, are relatively open to acquisitions by cross-border workers, while others apply stricter criteria. A notary or specialized lawyer can advise on the specifics of your target canton.

Specific mortgage conditions for cross-border workers

Swiss banks apply stricter criteria for cross-border workers than for residents. These reinforced conditions reflect the perceived risk profile: no tax domicile in Switzerland, income sometimes in foreign currencies, and a cross-border legal framework.

Increased equity: 25 to 30%

Where a Swiss resident or C permit holder must provide 20% equity, a cross-border worker generally needs 25 to 30% of the property value. Moreover, the share of "hard" equity (savings, pillar 3a, gifts) is often higher, with banks limiting or excluding the use of the 2nd pillar (LPP/BVG).

Reduced LTV: 65 to 75%

The loan-to-value (LTV) ratio granted to cross-border workers is typically limited to 65 to 75% of the property value, versus 80% for a resident. In practice, for a property worth CHF 1,000,000, the bank will finance at most CHF 650,000 to 750,000 through the mortgage, with the remainder covered by equity.

Affordability and income discount

Affordability is calculated using the same principles as for residents: theoretical mortgage charges (calculated at a reference rate of 5%) must not exceed one-third of gross income. However, two specifics apply to cross-border workers:

• Foreign currency income discount: If you are paid in euros (or another non-CHF currency), banks apply a 15 to 20% discount to cover exchange rate risk. A gross annual salary of EUR 80,000 will be counted at approximately EUR 64,000 to 68,000 in the affordability calculation.
• CHF income: If your employment contract is denominated in Swiss francs, this discount does not apply, which is a significant advantage.
• Employment stability: A permanent employment contract (CDI/unbefristeter Vertrag) is almost always required. Fixed-term or temporary contracts are rarely accepted.

Amortization: sometimes reinforced requirements

Mortgage amortization follows in principle the same rules as for residents: the 2nd lien (the portion above 65% of the property value) must be amortized within 15 years or before retirement. However, some banks impose on cross-border workers:

• Accelerated 2nd lien amortization (10 years instead of 15)
• Partial 1st lien amortization to bring the LTV below a certain threshold
• Direct amortization rather than indirect, limiting the tax advantages

Exchange rate risk: a key factor

For cross-border workers earning their salary in euros, exchange rate risk is a major concern. Mortgage charges (interest and amortization) are denominated in Swiss francs, while income is in euros. An appreciation of the Swiss franc against the euro mechanically increases the weight of mortgage charges in the household budget.

Historically, the Swiss franc tends to appreciate against the euro. Between 2010 and 2025, the EUR/CHF exchange rate went from approximately 1.40 to approximately 0.94, representing a franc appreciation of over 30%. This is precisely the risk that banks seek to cover with the foreign currency income discount.

Strategies to mitigate exchange rate risk:

• Prefer an employment contract in CHF if possible
• Regularly convert part of your income to CHF to build a reserve
• Negotiate a long-term fixed rate to secure monthly payments
• Some banks offer mortgages in euros, but rates are generally less favorable

Which banks accept cross-border workers?

Not all Swiss banks accept cross-border worker applications. The choice is more limited than for residents, but several categories of institutions are receptive:

Cantonal banks in border cantons

The cantonal banks of Geneva (BCGE), Vaud (BCV), Neuchatel (BCN), Basel, or Ticino (BancaStato) have significant experience with cross-border applications, given the geography of their cantons. They understand the specifics of this clientele and often offer adapted conditions. Their criteria nonetheless remain strict regarding equity and LTV.

Major national banks

Major Swiss banks (UBS, Raiffeisen, etc.) accept some cross-border worker applications, but with standardized processes that may lack flexibility for atypical profiles. Conditions generally align with maximum requirements (30% equity, 70% LTV).

Insurance companies and pension funds

Some insurance companies offer mortgages to cross-border workers with sometimes different criteria from banks. Rates may be slightly higher, but flexibility on the borrower's profile is sometimes greater.

The advantage of a mortgage broker

Given the complexity of the banking landscape for cross-border workers, using a mortgage broker is particularly relevant. The broker:

• Knows precisely which banks accept cross-border workers and their specific criteria
• Directs your application to the institutions most likely to accept it
• Negotiates conditions (rate, equity, amortization) in your favor
• Avoids multiple rejections that can harm your profile with banks
• Manages the administrative complexity linked to cross-border status

Cross-border worker taxation when owning property in Switzerland

The taxation of a cross-border worker owning property in Switzerland is a complex subject that depends on the double taxation agreement between Switzerland and the country of residence.

France-Switzerland tax treaty

For cross-border workers residing in France -- who represent the majority in French-speaking Switzerland -- the tax situation is as follows:

• Income taxation: Depending on the work canton, the cross-border worker is taxed either in Switzerland (at source, for cantons like Geneva, Zurich, etc.) or in France (for cantons applying the 1983 cross-border worker agreement, such as Vaud, Valais, or Neuchatel)
• Property taxation in Switzerland: The property is subject to property tax and imputed rental value tax in the canton where it is located, under Swiss law
• Declaration in France: The cross-border worker must declare the Swiss property in their French tax return, even if already taxed in Switzerland. A double taxation elimination mechanism applies.
• Mortgage interest deductibility: Mortgage interest is deductible in the Swiss canton for the imputed rental value. In France, deductibility depends on the applicable tax regime.

Capital gains tax on property

Upon resale, a real estate capital gains tax is due in Switzerland. The rate is degressive based on the length of ownership (the longer the ownership, the lower the rate). Specific provisions vary by canton.

Required documents for a mortgage application

A cross-border worker's mortgage application must be particularly well-prepared. Here is the list of generally required documents:

Identity and status documents

• Identity document (passport or ID card)
• Valid G permit
• Proof of residence in the country of residence
• Criminal record extract (depending on the bank)

Income documents

• Swiss employer attestation (position confirmation, seniority, contract type)
• Last three payslips
• Employment contract
• Previous year's salary certificate
• Most recent tax assessment from the country of residence

Financial documents

• Bank statements from the last 3 to 6 months (Swiss and foreign accounts)
• Proof of origin of equity
• LPP pension certificate (if applicable)
• Pillar 3a statement (if applicable)
• Statement of debts and current commitments (leasing, consumer credit, etc.)

Property documents

• Property description
• Market value estimate or agreed purchase price
• Land registry extract
• Plans and photographs

Concrete example: financing for a cross-border worker

Let us take the example of Sophie, a French cross-border worker living in Annemasse and working in Geneva. She wants to buy an apartment in Thonex (GE) valued at CHF 900,000.

In this example, Sophie is paid in CHF (no currency discount), has sufficient equity, and the charge ratio stays below the 33% threshold. Had she been paid in euros, her income would have been discounted by 15 to 20%, which could have jeopardized affordability.

Practical steps to obtain your mortgage

1. Check your eligibility: Confirm that you can acquire property in the target canton (border zone, Lex Koller authorization)
2. Assess your affordability: Use our mortgage simulator to estimate your budget, taking into account any income discount
3. Build your equity: Gather at least 25 to 30% of the estimated property value, with proof of origin
4. Prepare a complete application: Collect all documents listed above, from both the Swiss and foreign sides
5. Consult a mortgage broker: Identify banks suited to your profile and obtain multiple comparative offers
6. Obtain cantonal authorization: If necessary, request acquisition authorization from the competent authority
7. Sign the purchase deed: The notary verifies your acquisition rights, formalizes the transaction, and registers the mortgage in the land registry

Common mistakes to avoid

• Underestimating required equity: Do not forget purchase and notary costs (3 to 5% of the price depending on the canton), which are added to the equity required by the bank
• Submitting multiple credit applications: Each bank rejection is recorded and can penalize future applications. Better to target the right banks from the start, with a broker's help
• Ignoring exchange rate risk: If paid in euros, simulate the impact of a 10 to 15% Swiss franc appreciation on your monthly charges
• Neglecting cross-border taxation: Consult a specialized tax advisor to optimize your situation between Switzerland and your country of residence
• Forgetting accelerated amortization: Budget for potentially higher amortization requirements than for a resident
