You're crossing 11 employees in 2026 — the mobility contribution (formerly "versement transport") now concerns you. How much, when, how, and can remote work alleviate it? This contribution, codified in CGCT Articles L. 2333-64 et seq., finances urban public transport and constitutes a significant SME charge: up to 2.95% of payroll in Île-de-France.
This practical 2026 guide details the activation threshold, rates by geographic zone, the 5-year smoothing mechanism, the impact of remote work and articulation with transport premium and sustainable mobility allowance.
Executive summary#
- Activation threshold: 11 FTE employees.
- 2026 rates: variable per organising authority (AOM) — Île-de-France 2.95%, Lyon 2.00%, Marseille 1.80%.
- Threshold neutralization: 5-year smoothing regime (0%, 25%, 50%, 75%, 100%).
- Permanent remote work outside AOM zone = exit from scope.
- Cumulation transport premium + FMD: possible and widely used.
1. Legal framework and mechanics#
Definition#
The mobility contribution is a mandatory employer charge dedicated to urban public transport financing. It is instituted by organising mobility authorities (AOMs) — Île-de-France Mobilités, SYTRAL Lyon, RTM Marseille, and about 200 other territorial AOMs in France.
Scope#
Applies to public and private employers with ≥ 11 FTE employees whose employees work in the geographic ressort of an AOM that has instituted the versement.
Base#
The base is the total gross remuneration of each employee, uncapped.
2. The 11-employee threshold and 5-year smoothing#
Headcount calculation#
The headcount counted for the threshold follows the standard URSSAF rule: annual average of monthly headcounts.
Included: CDI, CDD pro-rata, apprentices, professionalization contracts. Excluded: temp workers (in the temp agency's headcount), interns, seconded staff.
Smoothing regime (5-year)#
In case of crossing the 11-employee threshold in year N:
| Year | Contribution |
|---|---|
| N (crossing year) | 0% (full exemption) |
| N+1 | 25% of applicable rate |
| N+2 | 50% |
| N+3 | 75% |
| N+4 onwards | 100% |
This neutralization is codified in CGCT Article L. 2333-69-1.
3. Applicable rates by geographic zone 2026#
| AOM zone | 2026 rate (approximate) |
|---|---|
| Île-de-France Mobilités (Paris + inner ring) | 2.95% |
| Île-de-France Mobilités (outer ring) | 2.01% |
| SYTRAL Lyon | 2.00% |
| RTM Marseille | 1.80% |
| Toulouse Métropole | 1.90% |
| Bordeaux Métropole | 1.80% |
| Nantes Métropole | 1.80% |
| Strasbourg Eurométropole | 1.80% |
| Lille (MEL) | 1.80% |
| Communes < 100,000 inhabitants with AOM | 0.55% to 1.00% |
Rates set by annual decree and may evolve each 1 July.
Our expert view#
Classic trap: multi-establishment SMEs apply a single rate. Wrong. Each employee falls under the rate of their main place of work. For a 50-employee SME with Paris HQ (35 employees at 2.95%) and Lyon depot (15 employees at 2.00%), the DSN must distinguish the two zones. A 50-person SME with €2.5M payroll split 75/25 pays: €1.875M × 2.95% + €0.625M × 2.00% = €55,312 + €12,500 = €67,812 per year. A line item that deserves precise monthly monitoring.
4. Remote work and impact on contribution#
Permanent remote work#
If an employee is in permanent 100% remote work in a department outside the AOM zone, they are no longer in the versement scope. Consequence: partial exit from base.
Partial remote work (1-4 days)#
If the employee is in partial remote work but their main workplace remains in the AOM zone, the contribution remains due on their entire remuneration. No proration.
Reclassification risk#
An AOM can challenge "fictitious" remote work if the company declares employees outside the zone while they regularly come to the HQ.
5. Worked example — 25-employee SME in Lyon, 40% remote#
Profile: services SME with 25 employees in Lyon, €1.3M payroll, 40% time in remote work (8 full-time home employees, including 3 outside the SYTRAL zone).
| Item | Calculation |
|---|---|
| Employees in SYTRAL zone (22) | 22 × €52,000 avg payroll = €1,144,000 |
| 2.00% mobility contribution | €22,880/year |
| Employees outside SYTRAL zone (3) | 3 × €52,000 = €156,000 |
| Mobility contribution on them | €0 (outside zone) |
| Total 2026 mobility contribution | €22,880 |
Exiting 3 employees from SYTRAL via permanent remote work saves approximately €3,120/year.
6. Articulation with transport premium and sustainable mobility allowance (FMD)#
| Device | Nature | Beneficiary |
|---|---|---|
| Mobility contribution | Mandatory employer charge | AOM (public transport) |
| Transport premium | Direct employer aid | Employee (50% public transport subscription mandatory) |
| Sustainable mobility allowance (FMD) | Optional direct employer aid | Employee (bike, carpool, electric scooter, etc.) |
2026 FMD ceilings#
- €800/year per employee exempt from social contributions and IR (raised by LF 2024 from €700 to €800).
- Cumulation possible FMD + transport premium within global cap.
The underestimated risk#
Many employers neglect the sustainable mobility allowance while it's one of the most profitable HR devices: €800/year totally exempt from contributions = equivalent to €1,700 of gross salary. A low-cost HR investment that improves package perception while indirectly reducing carbon footprint — important ESG argument for young talents.
7. Director decision checklist#
- Headcount diagnosis: above or below 11 FTE?
- If crossing: have I activated the 5-year smoothing?
- Multi-establishment: DSN ventilation per AOM zone correctly set up?
- Permanent remote work: formal remote-work policy outside zone.
- FMD and transport premium: HR policy in place, 2026 ceilings used?
- Rate monitoring: URSSAF newsletter subscription.
8. 2026 watchpoints#
- Rate updates: generally published in July for application from 1 July.
- New AOMs: some intercommunalities may institute a versement during the year.
- URSSAF audit: cross-check with DSN and payslips. Zone error = back-charge with interest.
- Transport premium coordination: since 2025, the obligation to cover 50% of public transport subscription costs is integrated.
Closing thoughts#
The mobility contribution is a significant employer charge — up to 2.95% in Île-de-France — that can weigh heavily on payroll. Its proper management involves 4 levers: precise threshold monitoring and 5-year smoothing, rigorous multi-establishment DSN ventilation, intentional remote-work policy, and FMD/transport premium optimisation.

Frequently asked questions
À partir de combien de salariés mon entreprise paie-t-elle le versement mobilité ?
Le seuil de déclenchement est de 11 salariés ETP (équivalent temps plein). L'effectif s'apprécie au 31 décembre de l'année N pour les obligations de l'année N+1 (CGCT art. L. 2333-64). En cas de franchissement, une période de neutralisation de 5 ans s'applique : pas de cotisation due la première année du franchissement, puis cotisation à 25 %, 50 %, 75 %, 100 % les années suivantes (régime de lissage CGCT art. L. 2333-69-1).
Le télétravail réduit-il automatiquement ma cotisation versement mobilité ?
Pas automatiquement. La cotisation s'applique aux salariés dont le lieu de travail est situé dans le ressort géographique d'une autorité organisatrice de la mobilité (AOM) ayant institué le versement. Si vos salariés sont en télétravail permanent (100 %) dans un autre département hors zone AOM, ils ne sont plus dans l'assiette du versement mobilité. Pour le télétravail partiel (1-4 jours), la cotisation reste due sur l'intégralité de leur rémunération si leur lieu de travail principal est dans la zone AOM.
Les CDD et alternants sont-ils dans l'effectif décompté ?
Oui. L'effectif décompté pour le seuil de 11 salariés inclut tous les salariés en CDI, CDD (au prorata de la durée du contrat sur l'année), apprentis et contrats de professionnalisation (avec règles spécifiques). Sont exclus : intérimaires (comptés dans l'effectif de la société d'intérim), stagiaires conventionnés, salariés mis à disposition. Le calcul de l'effectif moyen suit la formule URSSAF standard (effectif moyen annuel sur 12 mois).
Quel taux pour une PME multi-établissements (siège Paris + dépôt Lyon) ?
Le taux applicable dépend du lieu de travail effectif de chaque salarié. Pour un siège à Paris (taux Île-de-France ~2,95 % en 2026) et un dépôt à Lyon (taux SYTRAL Lyon ~2,00 %), chaque salarié relève du taux de son lieu de travail principal. La déclaration en DSN distingue ces zones par établissement. Pour un salarié dont l'activité s'exerce dans plusieurs zones AOM (commercial itinérant), le taux applicable est celui du siège d'affectation.
Versement mobilité ou prime transport — sont-ils cumulables ?
Oui, ce sont deux mécanismes distincts. Le versement mobilité est une cotisation à la charge de l'employeur (financement transport public). La prime de transport ou le forfait mobilités durables (FMD) sont des aides directes à l'employé. Les deux sont totalement cumulables : l'employeur paie la cotisation patronale ET peut, indépendamment, verser au salarié une indemnité de transport (50 % de l'abonnement transport public ou jusqu'à 800 €/an de FMD en 2026, exonérée de cotisations sociales et d'IR dans la limite).
