France mobility contribution 2026: versement mobilite, remote work and employer guide

Updated 2026-05-26 — reviewed by Hayot Expertise, registered chartered accountant (Paris 16th).

You are approaching the 11-employee mark, or you already manage payroll above the threshold. The mobility contribution (cotisation mobilites, formerly versement transport) can represent up to 3.20% of your gross payroll in the Paris inner ring. It is consistently one of the most under-monitored payroll items in growing French SMEs.

This 2026 guide covers the four questions that come up most often in payroll engagements: who is actually liable, which rate applies, how remote work is treated by the administration, and how to calculate the contribution accurately by zone.

The mobility contribution is owed by all private and public employers with a workforce of at least 11 employees whose staff carry out activity within the geographic area of an organising mobility authority (AOM — autorite organisatrice de la mobilite) that has instituted the levy.

Since the Pacte law (2019), crossing the 11-employee threshold only triggers the obligation after 5 consecutive calendar years above the threshold. If your company first reaches 11 employees in 2021 and stays at or above that level through 2025, you become liable from 1 January 2026. If the headcount drops below 11 during those 5 years, the counter resets.

One frequently misunderstood point: the neutralisation is not a graduated ramp-up (25%, 50%...). The contribution jumps directly from 0% to the full applicable rate in year 6. There is no phased entry for this particular threshold.

Any company with at least 11 employees in a municipality belonging to an AOM that has voted to institute the levy. In practice this covers almost all urban areas in France. Two main exclusions exist: non-profit associations with a social character (under conditions) and employers located entirely outside any AOM perimeter — mainly rural areas.

From 1 January 2026, a regional and rural mobility contribution (VMRR — versement mobilite regional et rural) has been introduced in several regions (Brittany, Centre-Val de Loire, Bourgogne-Franche-Comte, parts of Occitanie, Nouvelle-Aquitaine and PACA), capped at 0.15% for employers located outside a standard AOM zone. This development deserves attention for businesses that previously assumed they had no mobility levy exposure.

Each AOM sets its own rate within statutory limits. Rates may change on 1 January and 1 July each year. To find the exact rate for your establishment address, use the URSSAF postcode search tool or the November 2025 circular letter for rates effective 1 January 2026.

Our read. The Paris inner-ring rate increased from 2.95% to 3.20% in February 2024, under Article 139 of the 2024 Finance Act. For an SME with 20 employees and a EUR 1.5 million annual payroll in Paris, the difference is EUR 3,750 per year. Firms that did not update their DSN parameter at the time accumulated a shortfall that comes due with late-payment penalties at URSSAF audit.

The calculation is straightforward. The base is the remuneration subject to employer sickness insurance contributions — in practice the full gross salary, with no Social Security ceiling. Professional expense reimbursements and benefits in kind that are normally excluded from the SS base are excluded here too.

Calculation steps#

1. Identify the establishment of attachment for each employee (town, postcode).
2. Confirm that establishment is within an AOM that has instituted the levy.
3. Retrieve the applicable rate via the URSSAF search engine or the November 2025 circular for 2026 rates.
4. Apply: monthly gross payroll base x rate = monthly contribution.
5. Declare in the DSN (contribution block, mobility contribution type code for the establishment).
6. Check the payroll software parameter: each establishment must carry its own AOM code and rate.

Worked example — 18-employee SME in the Paris inner ring#

An 18-employee professional-services firm based in the Hauts-de-Seine (92), with a monthly gross payroll of EUR 90,000.

In payroll files we handle, SMEs that crossed the threshold several years ago and whose Paris DSN parameter was not updated from 2.95% to 3.20% in February 2024 have accumulated a shortfall. Catching up at an URSSAF audit means paying arrears plus late-payment surcharges. Checking the parameter takes under an hour.

This is the most common question since hybrid working became standard. The short answer: partial remote work does not reduce the mobility contribution.

The contribution applies to employees whose contractual workplace is in the AOM zone. It is the place of attachment stated in the employment contract (or in an addendum) that matters — not where the employee sits physically on any given day. An employee working two or three days per week from home is still attached to the Paris establishment for mobility contribution purposes.

The administration's position#

URSSAF's consistent position is that liability is determined by the habitual place of work (contractual place of attachment), not by actual physical presence. A remote-work agreement alone does not change that attachment. Reassigning an employee out of the AOM zone requires a formal contractual addendum (avenant) specifying the new principal place of work — and the reassignment must be operationally credible (badge records, IT connection logs, consistent physical presence data).

The two situations where remote work actually affects the base#

The underestimated risk. Some employers declare employees as working outside the AOM zone on the basis of an informal remote-work arrangement, without a contractual addendum and without consistent badge or system-access records. The AOM or URSSAF can challenge this classification at audit — resulting in reassessments, late-payment surcharges and, in the most serious cases, characterisation as partial illegal employment. Documentation to retain: signed employment addendum, formal telework plan, evidence of the employee's habitual workplace.

Each establishment has its own SIRET number and its own applicable rate. The DSN must be configured establishment by establishment — a single-rate declaration across the whole payroll is a common error that leads to both overpayment (for low-rate establishments) and underpayment (for high-rate ones).

For itinerant employees (sales representatives, field engineers) without a fixed workplace, the attachment is the contractual establishment of hire. If the employee spends more than three months continuously in a different zone, a review of the attachment may be needed.

Example: Paris head office (3.20%) and Lyon satellite office (rate to verify at urssaf.fr), 30 employees split 20/10, total payroll EUR 1.8 million:

Applying a flat 3.20% across the entire payroll would have produced EUR 57,600 — an overpayment of EUR 7,200 per year.

These three devices are independent and fully cumulative.

The FMD ceiling is EUR 600 per employee per year in 2026, exempt from social contributions and personal income tax within that limit. When combined with mandatory public-transport reimbursement, the overall exemption ceiling rises to EUR 900 per year.

The FMD is consistently under-used in Paris SMEs. Yet EUR 600 fully exempt equates to roughly EUR 1,200 of gross payroll cost — an unusually efficient cost-per-perceived-value ratio for an employer benefit, and one that resonates well with employees who commute by cargo bike, e-scooter or car pool.

• Liability check: has the 11-employee threshold been maintained for 5 consecutive calendar years? If yes, from when?
• DSN rate audit: does each establishment carry the correct rate in the payroll software? Was the Paris rate updated to 3.20% in February 2024?
• Remote and itinerant employees: is the contractual attachment documented and operationally coherent?
• VMRR: if the business has establishments in rural zones in participating regions, has the regional levy been factored in since January 2026?
• FMD: is a sustainable mobility allowance policy in place? Are the 2026 ceilings correctly configured (EUR 600 / EUR 900)?

Rates may change on 1 July 2026 — a URSSAF circular is published in June. Sign up for URSSAF alerts or delegate this monitoring to your payroll manager.

The VMRR is a new device (first regions from 1 July 2025, further regions from January 2026). Not all payroll software vendors have integrated the corresponding contribution codes promptly — verify the configuration with your software provider or payroll firm.

The VMRR assessment base is identical to that of the standard mobility contribution — any error in the SS base propagates automatically to both levies.
