Employee transport costs in France 2026: obligations, sustainable mobility package and payroll

Commuting reimbursement obligations under French labour law are more complex than they appear. Three distinct mechanisms coexist: a mandatory public transport subscription contribution, a strictly conditioned allowance for personal vehicle use, and the voluntary but rigorously framed forfait mobilités durables (FMD, sustainable mobility package). Each has its own ceiling, eligibility conditions, and payroll treatment. Mixing them up — or applying them without proper documentation — is one of the most common sources of URSSAF audit adjustments for small and mid-size companies in France.

In brief: in 2026, every French employer must contribute at least 50% of each employee's public transport pass, with a social-charge exemption extended to 75%. The FMD allows up to EUR 600/year in additional tax-exempt allowances for eligible green commuting modes. Combined, the two mechanisms can reach EUR 900/year exempt. Personal vehicle allowances remain marginal and strictly conditional.

Every employer operating in France, regardless of size or sector, must cover at least 50% of the cost of public transport passes used by employees for their commute. This applies to monthly or annual passes — Navigo, TER regional trains, Transilien suburban rail, and public bike-sharing subscriptions — but not to individual single-use tickets.

For 2026, a temporary measure extends the social-charge exemption to 75% of the pass cost. This means that if the employer voluntarily covers more than the 50% minimum, the additional contribution up to 75% remains exempt from social contributions. Anything above 75% becomes a taxable benefit.

The required supporting document is simple: a nominal (named) copy of the employee's current subscription, showing the monthly or annual cost.

The FMD is an optional allowance that employers may pay to employees who use certain low-emission modes for their commute. The social-charge and income-tax exemption ceiling is EUR 600 per year.

Eligible transport modes for the FMD in 2026#

The following modes qualify:

• personal bicycle or electric bicycle;
• carpooling, whether as driver or passenger;
• motorised personal mobility devices (trottinettes, electric scooters in shared schemes, etc.);
• low-emission shared mobility (car-sharing, shared bikes);
• public transport (excluding passes already covered under the mandatory contribution).

Excluded modes#

The following are explicitly excluded: a personally owned non-shared vehicle, taxis and ride-hailing (VTC), intercity trains covered by a standard subscription, and walking.

The fuel cost sub-limit within the FMD#

Employees may include fuel costs under the FMD, but only up to EUR 300/year within the EUR 600 global ceiling. This sub-limit disappears entirely when the FMD is combined with a public transport subscription reimbursement.

One of the most misunderstood points: an employee can combine the mandatory public transport contribution and the FMD in the same year. When both are used, the total exempt amount rises to EUR 900/year. However, when the combination is applied, fuel costs are no longer eligible for the FMD exemption.

French labour law allows employers to reimburse personal vehicle commuting costs, but only in clearly restricted situations: the employee works outside the Paris Île-de-France region and major urban areas, or their working hours are incompatible with public transport (night shifts, atypical schedules, poorly served sites). This is not a general right — it is a narrow exception.

The 2026 exempt ceilings are:

Any amount paid beyond these ceilings, or paid outside the restrictive eligibility conditions, is subject to social contributions.

An employer wishing to establish a FMD must formalise the decision through one of three routes:

1. Company-level collective agreement: negotiated with employee representatives, typically for companies with an active works council (CSE).
2. Industry-level agreement (accord de branche): if the applicable collective agreement already provides for a FMD.
3. Unilateral employer decision (DUE): after consulting the CSE if one exists. This is the fastest route for SMEs and the most commonly used.

Any modification to the FMD conditions — amount, eligible modes, required documentation — requires one month's notice before the change takes effect.

Payroll treatment is where compliance often breaks down. Both the public transport reimbursement and the FMD must appear as separate, named line items on the French pay slip (bulletin de paie). The transport reimbursement line must show the reimbursed amount; the FMD line must show the allowance paid and the exempt status.

Absent or incorrect labelling is one of the most frequent findings in URSSAF transport-related audits. A well-intentioned practice that cannot be traced on the pay slip or through supporting documents loses its exempt status in the event of a challenge.

Several patterns come up consistently in employer files:

• Applying a 50% transport reimbursement without reviewing whether the 2026 extension to 75% creates a useful HR opportunity.
• Operating an informal FMD with no DUE, no CSE consultation, and no written justification from employees — common in startups and small consulting firms.
• Confusing the FMD with kilometric allowances for business travel. These are two entirely separate mechanisms with different rules, ceilings, and tax treatment.
• Pro-rating the public transport contribution based on telework days. This is incorrect: the obligation is not reduced by the number of days the employee works remotely.
• Treating the fuel sub-limit as still applicable when combining FMD with a transport pass reimbursement.

A labour charge inspector reviewing transport costs will typically focus on three things: the existence of a named, dated supporting document for each beneficiary; the coherence between the declared transport mode and the mechanism applied; and compliance with the annual exemption ceilings, particularly when both FMD and transport subscription are combined.

The absence of documentation is interpreted against the employer. An arrangement that is substantively correct but cannot be evidenced will be reclassified as a taxable benefit.

Consider a small consulting firm of eight employees based in central Paris. The picture breaks down as follows.

Employee A commutes by Navigo monthly pass at EUR 88.80/month (EUR 1,065.60/year). The employer covers 75%: a reimbursement of EUR 66.60/month (EUR 799.20/year), fully exempt from social charges.

Employee B cycles to the office on a personal electric bicycle. The employer has established a FMD via a unilateral employer decision (DUE). The employee receives EUR 600/year, paid in one instalment in December on the basis of a signed personal declaration. The amount is fully exempt from social charges and income tax.

Employee C combines a Navigo pass (50% covered: EUR 532.80/year) with a FMD for cycling (EUR 300/year). Total exempt: EUR 832.80, well within the EUR 900 combined ceiling. No fuel costs are included in the FMD since the combination is in use.

On the pay slip, each of these three employees has a distinct, clearly labelled line: "Remboursement abonnement transport" for A and C, "Forfait mobilités durables" for B and C. The treatment is consistent, documented, and auditable.

The following structured approach is what we recommend to any employer who wants to put their transport arrangements in good order:

1. Map all active mechanisms in the company: mandatory transport contribution, FMD, personal vehicle allowance, any above-minimum voluntary policy.
2. Create separate payroll codes in the payroll software for each mechanism, with the correct exempt ceilings configured.
3. Assign each employee to the correct mechanism based on their documented commuting mode.
4. Set annual ceiling alerts for the FMD (EUR 600 standalone, EUR 900 when combined with a transport pass).
5. Collect supporting documents at the start of each year or at each renewal: a nominal copy of the transport pass, a signed personal declaration for the FMD.
6. Run a half-yearly check to verify that documents on file match the amounts coded in payroll.

This process does not require significant time. It does require consistency. The companies that face difficulty in audits are rarely those that made a wrong choice — they are those that made no documented choice at all.

Two developments are reshaping how French employers manage transport costs. First, the widespread adoption of hybrid working has created employees who commute two or three days per week. The mandatory transport contribution still applies in full — but this also opens the question of whether a FMD covering bike use on office days is worth adding.

Second, the growth of electric and cargo bike use in urban areas is making the FMD more visible as an HR differentiator. For companies competing for talent in Paris and other major cities, the combination of 75% transport coverage and a EUR 600 FMD represents a meaningful net benefit, at relatively low cost to the employer, particularly compared with car-related benefits.

A transport policy that was designed five years ago — when most employees commuted five days a week and the FMD did not exist in its current form — is likely overdue for review.

On the payroll engagements we run with Parisian SMEs and professional service firms, the transport topic rarely requires a heavy intervention — but it does require a structured one. A one-page internal policy defining the applicable mechanism, the eligible employees, the required documents, and the payroll lines is usually sufficient to put the company in a defensible position.
