Swiss cross-border workers: convert your CHF salary to euros at the best rate

What Converting Your Salary Really Costs

The cost of conversion isn't displayed as a fee line item. It is hidden in the exchange rate: the bank buys your francs at a less favourable rate than the market rate and pockets the difference. With a traditional bank account, this spread is often between 3% and 4%.

Take a net salary of CHF 6,000 per month. A 3% margin represents around CHF 180 per month, or more than CHF 2,000 per year. Over a cross-border worker's career, the difference amounts to tens of thousands of euros.

Options for Converting Your Swiss Salary

• A transfer from your Swiss bank to your French bank: simple, but often the most expensive option, involving an exchange rate margin and sometimes transfer fees.

• A Swiss franc account with a French bank: convenient, but the conversion is still carried out at the bank's exchange rate.

• Money transfer apps: near-market rates and transparent fees, highly appealing for modest amounts. However, percentage-based fees add up month after month.

• An international payments specialist: near-market rates, a dedicated point of contact, and tools to schedule or lock in your conversions.

The Real Issue: Currency Risk on Your Euro Expenses

Your salary is in francs, but your living costs are in euros: mortgage, rent, school fees. When the franc strengthens, your purchasing power increases; when it weakens, your budget tightens without your salary changing.

To smooth out this effect, several solutions exist:

• Convert on a set date, every month, to avoid trying to time the market.

• Lock in the exchange rate in advance for a portion of your conversions over several months, using a forward contract to secure the cost of your mortgage repayments.

• Group your conversions together rather than carrying out multiple smaller transactions.

Buying in France, Paying in Francs: The Case of the Mortgage

Many cross-border workers buy property in Haute-Savoie, Ain, or the Pays de Gex with income in francs. The loan is in euros, the income in francs: every drop in the franc increases the real cost of the monthly repayment. Securing a portion of the conversion rate over the year provides predictability for a budget that would otherwise fluctuate every month.

What About Buying in Switzerland?

Purchasing property in Switzerland by a non-resident is governed by the federal law known as the Lex Koller, which subjects many acquisitions to authorization. Cross-border commuters are subject to specific rules: before starting any project, check with the relevant cantonal authority or a Swiss notary.

Frequently Asked Questions

What is the best way to convert a Swiss salary into euros?

The method that combines a near-market rate with a schedule tailored to your expenses. For a monthly salary, a foreign exchange specialist or a dedicated app is generally more advantageous than a standard bank conversion.

How much does a CHF to EUR conversion cost at a bank?

A traditional bank's foreign exchange margin is often between 3% and 4% of the converted amount, to which transfer fees may also be added.

Do I need to declare my Swiss bank account?

Yes. A French tax resident must declare foreign accounts each year, including those held in Switzerland, using form 3916.

Can you lock in the CHF/EUR exchange rate in advance?

Yes, with a forward contract, which fixes the rate today for a future conversion. This is useful for securing the cost of recurring expenses in euros.
