How to Issue a Compliant French Payslip in 2026: A Complete Employer’s Guide

Introduction: Why a Compliant Payslip Matters

The payslip (bulletin de paie) is the central document in the employment relationship between employer and employee. It reflects the employment contract in performance, details the remuneration paid and the contributions withheld. In 2026, regulatory requirements have evolved further, notably with the consolidation of the net social amount (montant net social – MNS) and the extension of the provisional simplified payslip template until 31 December 2026. For HR departments and payroll managers, mastering these obligations is essential to avoid labour court (prud’hommes) litigation and URSSAF reassessments.

This complete guide walks you step by step through issuing a payslip that complies with the French Labour Code, the BOSS (Bulletin Officiel de la Sécurité Sociale – the official social security bulletin) and the applicable ministerial orders. We will address each section of the payslip, the mandatory entries, the calculation of the MNS, the tax section relating to withholding tax at source (prélèvement à la source – PAS), and the retention obligations.

Mandatory Entries on the Payslip (Article R.3243-1 of the French Labour Code)

Article R.3243-1 of the French Labour Code provides an exhaustive list of the entries that must appear on the payslip. The BOSS, in its section dedicated to payslips, restates and clarifies these obligations. The essential elements are as follows.

Employer Identification Section

This section must include:

The employer’s name and address, or the establishment’s business name and address
The SIRET number of the establishment
The APE code (principal activity carried out)
The reference of the body to which the employer pays social security contributions (the competent URSSAF office)
The applicable collective bargaining agreement (convention collective) or, failing that, a reference to the Labour Code for provisions relating to paid leave and notice periods

In practice, most payroll software populates this information automatically from the initial company setup. However, its accuracy should be checked regularly, particularly in the event of a change of address, APE code or collective bargaining agreement.

Employee Identification Section

Information relating to the employee includes:

The employee’s surname and first name
The position held and the collective bargaining classification (level, grade, coefficient)
The period and number of working hours to which the remuneration relates, distinguishing between hours at the normal rate and overtime hours (with the applicable premium rate stated)
The nature of the basis for calculating the salary where it is not working time

Gross Remuneration Section

Gross remuneration comprises all the elements making up the salary. The BOSS specifies that the following must appear separately:

The base salary
Bonuses and gratuities (seniority bonus, 13th month, performance bonus, etc.)
Benefits in kind valued according to the applicable scales
Overtime hours with their premium rate
Salary maintenance during an absence (sickness, maternity, etc.)
Paid leave allowance

Concrete example: An executive employee with a monthly base salary of €3,500, a seniority bonus of €175 and a company vehicle benefit in kind valued at a flat rate of €350 will have gross remuneration of €4,025.

The simplified payslip, whose provisional template is maintained until 31 December 2026, groups contributions into major blocks to make them easier to read. The contribution lines must show:

Employee and Employer Contributions

For each contribution or group of contributions, the payslip must indicate:

The contribution base
The employee rate and the employer rate
The employee amount and the employer amount

The main blocks of the simplified payslip are as follows:

Health: supplementary health cover, provident insurance (prévoyance)
Workplace accidents – Occupational illnesses
Retirement: capped and uncapped social security, supplementary (Agirc-Arrco)
Family
Unemployment insurance
CSG/CRDS: deductible CSG, non-deductible CSG, CRDS
Other employer contributions: vocational training, apprenticeship tax, etc.

In 2026, the monthly social security ceiling (plafond mensuel de la sécurité sociale – PMSS) is set at €4,005. This ceiling determines the calculation of many contributions (capped basic retirement, Agirc-Arrco tranche 1, etc.). It must be prorated in the event of part-time work or entry/exit during the month.

Example: For an employee working 80%, the prorated monthly ceiling is €4,005 x 0.80 = €3,204.

Introduced by the order of 31 January 2023 and made mandatory on all payslips since 1 January 2024, the net social amount is essential data for employees, particularly for their dealings with the CAF (family allowance fund) and France Travail (the employment agency).

Definition and Calculation of the MNS

According to the BOSS, the net social amount is defined as follows:

MNS = Total gross remuneration – Mandatory social contributions borne by the employee

The elements taken into account in gross remuneration for calculating the MNS include:

The base salary
Bonuses (seniority, 13th month, performance, etc.)
Benefits in kind (meals, accommodation, vehicle, IT/telecom equipment)
Salary maintenance during a leave (sickness, maternity)
Overtime and additional hours
Paid leave allowance
Social security daily allowances (IJSS) paid by subrogation

The elements not taken into account (excluded from gross remuneration for the MNS):

Reimbursements of professional expenses (mileage allowances, transport reimbursement, etc.)
Social security daily allowances paid directly to the employee by the CPAM (without subrogation)
Exempt social benefits (holiday vouchers within the exemption limit, etc.)

Worked Example of the MNS Calculation

Take a non-executive employee with the following items:

Base salary: €2,500
Seniority bonus: €125
Meal benefit in kind: €5.50 x 20 days = €110
Transport reimbursement: €45 (excluded from the MNS)

Gross remuneration for the MNS: 2,500 + 125 + 110 = €2,735

Mandatory employee contributions: approximately 22% of 2,735 = €601.70

MNS = 2,735 – 601.70 = €2,133.30

This amount must appear on a dedicated line of the payslip, clearly identified under the heading “Montant net social” (net social amount).

Net Pay Before and After Withholding Tax at Source (PAS)

Net Pay Before Income Tax

Net pay before PAS corresponds to the amount the employee would receive if there were no tax deduction. It is calculated as follows:

Net pay before PAS = Gross remuneration – Total employee contributions + Expense reimbursements – Benefits in kind (deduction)

The Withholding Tax Section

The BOSS reminds that the tax section relating to the PAS is mandatory on the payslip, even where the amounts are nil (for example, for an employee whose PAS rate is 0%). This section must indicate:

The PAS base (net taxable income)
The rate applied (personalised rate, neutral rate or individualised rate)
The amount of PAS withheld

Example: For a net taxable income of €2,200 and a personalised rate of 7.5%, the PAS amount will be 2,200 x 7.5% = €165.

Net Pay to the Employee

The final net pay is calculated as:

Net pay = Net before PAS – PAS withheld

In our example: 2,200 – 165 = €2,035 (amount transferred to the employee).

The Simplified Payslip Template: Extended Until 31 December 2026

The provisional simplified payslip template, introduced to make the payslip clearer for employees to read, has been extended until 31 December 2026. This template groups contributions into broad categories and simplifies the presentation while retaining all mandatory entries.

The main advantages of this template are:

Improved readability for the employee
A logical grouping of contributions by the risk covered
Display of the total employer cost (optional but recommended)
Native integration of the net social amount

Payroll software publishers have incorporated this template into their solutions. It is nevertheless advisable to check the compliance of payslip layouts regularly, particularly during annual configuration updates.

Payslip Retention: a Minimum 5-Year Obligation

The employer is required to keep a copy of payslips for 5 years (Article L.3243-4 of the French Labour Code). This retention may be in paper or electronic form, provided the integrity, availability and confidentiality of the documents are guaranteed.

Since 1 January 2017, the employer may issue the payslip in electronic form, unless the employee objects. In that case, the employer must guarantee the availability of the payslip for 50 years or until the employee reaches the age of 75, via a compliant digital vault.

Points of vigilance:

In the event of a URSSAF audit, payslips must be produced for the audited period (generally 3 years plus the current year)
In the event of labour court litigation, the employee may produce their payslips as evidence with no time limit
Failure to deliver the payslip is punishable by a fine of €450 per missing payslip

The Most Common Mistakes to Avoid

Here are the mistakes we most frequently identify during our payroll compliance audits:

Omission of the MNS entry: since 2024, this entry is mandatory on all payslips. Its absence can lead to litigation with the employee.
Missing PAS section when the amount is nil: the BOSS is clear — the section must appear even if the amount withheld is €0.
Incorrect proration of the social security ceiling: for part-time employees or entries/exits during the month, the ceiling must be adjusted.
Incorrect or missing collective bargaining agreement: the IDCC and the name of the agreement must appear on each payslip.
Unvalued benefits in kind: benefits in kind must be assessed and shown both in gross and as a deduction from net.

Summary Table of Payslip Sections 2025

For a synthetic overview, here are the main sections of a compliant payslip:

Header: employer + employee identification + period
Body: detailed gross remuneration + contributions by block
Summary: total gross, total employee contributions, MNS, net taxable income, PAS, net pay
Footer: annual cumulative totals, retention notice, net-entreprises portal reference

FAQ: Your Questions on the Compliant Payslip in 2026

Yes, the net social amount (MNS) is a mandatory entry on all payslips since 1 January 2024, regardless of the employee’s profile. This obligation stems from the order of 31 January 2023. The MNS enables the employee to declare their income to the CAF or France Travail in a simplified manner. Its absence from the payslip constitutes a breach of the employer’s legal obligation.

Should the PAS section be included if the employee has a 0% rate?

Yes, the tax section relating to withholding tax at source is mandatory even where the amounts are nil. The BOSS explicitly states this obligation. The payslip must indicate the base, the rate (even at 0%) and the amount (even at €0). This entry allows the employee to verify that their rate is correctly applied and to ensure no configuration error exists.

How long must the employer keep payslips?

The employer must keep a copy of payslips for a minimum of 5 years in accordance with Article L.3243-4 of the French Labour Code. Where an electronic payslip is issued to the employee via a digital vault, the availability period is 50 years or until the employee reaches the age of 75. It is advisable to keep payslips beyond 5 years to be able to respond to potential labour court litigation, as the limitation period in salary matters is 3 years.

Is the simplified payslip template mandatory in 2026?

The simplified template has been mandatory since 1 January 2018 for all companies. The current provisional template is extended until 31 December 2026. All payslips must comply with the presentation by contribution blocks defined by ministerial order. Payroll software publishers incorporate this template into their solutions, but it is the employer’s responsibility to verify the compliance of its payslips.

What penalties apply for a non-compliant payslip?

Failure to deliver the payslip is punishable by a 3rd-class fine (€450) per missing payslip. A non-compliant payslip may also expose the employer to a reassessment of contributions during a URSSAF audit if the declared bases do not match the elements of the payslip. Finally, in the event of labour court litigation, an incorrect payslip may lead to damages awarded to the employee for breach of the obligation to deliver a compliant payslip.
