France–Switzerland 2025: The Coming Cross-Border Earthquake (Taxes, Healthcare, Rail, Jobs, Housing)

Cantons such as Geneva, Vaud and Neuchâtel are all reporting recruitment difficulties, especially in healthcare, precision industry and finance. In Switzerland, several politicians now openly mention revisiting tax agreements with France to:

• keep more source tax in Switzerland,
• finance infrastructure heavily used by cross-border commuters,
• reduce dependency on labour living in France.

In France, local mayors and national MPs argue instead for:

• stronger redistribution to border communes,
• higher contributions from Swiss employers who recruit massively in France,
• tighter checks on reported income and foreign accounts.

What is being discussed for 2025–2026:

• adjustments to withholding tax rates,
• new revenue-sharing formulas between France and Switzerland, canton by canton,
• reinforced automatic exchange of tax information.

For a typical cross-border household this could mean:

• losing 80 to 250 CHF per month depending on income and family profile,
• more complex annual returns, especially where part of the work is done remotely from France,
• a stronger need to optimise Swiss pension funds, third pillar savings and deductible expenses.

To refresh the current baseline rules, see our October overview Working across France and Switzerland and the focused health and social security guide France–Switzerland cross-border workers 2025.

With medical costs rising in Switzerland and public budgets under pressure in France, health coverage is again a hot topic. The French government has launched several reviews looking at:

• a possible increase in CMU contributions for cross-border workers,
• a gradual convergence of some CMU levels towards LAMal,
• stricter conditions to exercise or change the right of option.

The options currently on the table for 2025 include:

• moderate but real CMU contribution hikes,
• targeted checks for people living in France but only declared in the Swiss system,
• a reassessment of older situations seen as exemptions.

For cross-border workers the stakes are high:

• LAMal is more expensive but predictable,
• CMU can be attractive for families but is politically sensitive,
• Swiss media regularly mention a renewed focus on false or poorly documented frontier situations.

Ahead of any reform it is worth:

• comparing LAMal versus CMU every year, including for your partner and children,
• documenting clearly your residence in France (lease, bills, school certificates),
• keeping records of all health-related contributions on both sides.

Around Geneva the rail network is close to structural saturation. The Léman Express now carries far more daily passengers than initially planned. Forecasts for 2025 mention:

• more than 14 percent additional passengers on some segments,
• 20 to 40 minutes of extra delay during peak hours in major works periods,
• no easy way to increase capacity without upgrading rolling stock.

The CEVA line operators are already talking about:

• doubling trainsets on certain sections,
• heavy works from 2026 onward,
• emergency plans in case of failures or extreme weather.

For cross-border commuters this translates into:

• daily travel times lengthening by 12 to 25 minutes on average,
• more difficulty aligning childcare or school schedules with trains and buses,
• a renewed temptation to drive, with higher fuel, parking and maintenance costs.

To prepare, it helps to think of mobility as part of your overall project abroad. You can combine the tips from Getting around in Europe with the more lifestyle-focused advice in Building a life abroad.

On the French side of the border, communes near Geneva, Lausanne and Basel are under strong housing pressure:

• rents in many border towns have risen by 8 to 14 percent over 2024–2025,
• Swiss employees are buying more primary residences just across the border,
• family houses within 30–45 minutes of major employment hubs are becoming scarce.

Mayors in places like Saint-Julien-en-Genevois, Annemasse, Thonon and Ferney-Voltaire repeatedly warn they can no longer expand schools, roads and public services at the same pace as cross-border arrivals.

Possible levers for 2025 include:

• quotas for social housing units rented to cross-border households,
• higher property taxes in some high-pressure zones,
• tighter rules on short-term rentals around Geneva.

For cross-border workers this means:

• budgeting more generously for housing than five years ago,
• planning a move 6 to 12 months in advance,
• sometimes accepting a slightly more distant town in exchange for better rail links.

Switzerland remains close to full employment, with shortages in:

• precision industry and watchmaking,
• healthcare and care work,
• engineering, tech and cybersecurity,
• finance and specialised business services.

At the same time the federal and cantonal authorities are looking at ways to favour locally resident workers, for example:

• stronger language requirements for public-facing roles,
• more priority given to Swiss residents in subsidised sectors,
• tighter checks on foreign diplomas and certain private schools.

For cross-border candidates this implies:

• more detailed applications (references, mission descriptions, equivalence of degrees),
• higher expectations on French or German depending on the canton,
• a need to think of career strategy at European scale rather than canton by canton.

To structure this, you can combine the practical roadmap in finding your first job abroad with the mobility and compliance rules in Digital nomads 2025.

Behind the scenes a more radical scenario is now being discussed by some experts: a full renegotiation of the cross-border worker status between France and Switzerland.

Such a scenario, still hypothetical, could include:

• new reporting duties on the French side,
• a specific contribution to public infrastructure costs for heavy users,
• a dedicated health contribution somewhere between French and Swiss systems.

Nothing is decided yet, but the clear direction is towards more transparency, traceability and a finer sharing of the public costs generated by cross-border mobility. To stay informed, it is worth following our updates on residence and remote work, including EU residency changes 2025 and working remotely from another EU country.

Instead of reacting in panic, cross-border workers can build a simple playbook. Key levers include:

• include your partner and children, annual medical costs and age,
• factor in the price of top-up insurance if you stay in CMU.

1. Simulate CMU versus LAMal every year

• explore voluntary buy-ins when they make sense for tax,
• plan ahead if you intend to use pension assets to buy a home in France.

1. Optimise Swiss second and third pillars

• start housing searches early,
• test several commute options before signing a lease.

1. Plan housing and commuting 6–12 months ahead

• keep a monthly safety buffer in your budget,
• follow the banking and fee changes explained in EU banking revolution 2025 and Expat banking 2025: hidden fees.

1. Prepare for higher tax at source or in France

• bring concrete figures on housing and commuting costs to annual reviews,
• ask for partial coverage of rail passes or parking when justified.

1. Negotiate pay, bonuses and transport support

• leases, utility bills, school certificates, French tax assessments,
• secure digital copies ready to share if an administration asks for clarification.

1. Build a strong "proof of residence in France" file

Emma lives in France and works as an engineer in Lausanne, earning 105,000 CHF per year. Over 18 months she experiences:

• commute times increasing from 45 minutes to around 65 minutes door to door,
• a rent increase of roughly 220 euros per month,
• a potential CMU contribution rise of about 420 euros per year.

She reacts early instead of waiting for the next shock:

• she opens a dedicated account for CHF to EUR conversions, following the principles in our European expat banking pillar guide,
• she sets up a 300 CHF per month third-pillar plan to smooth future taxation,
• she adjusts her working hours to avoid the most congested trains,
• she negotiates part of her commuting costs with her employer.

Result: even after higher housing and health costs, she keeps several thousand euros a year compared with a no-optimization scenario.
