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

Introduction: Why a Compliant Payslip Matters

The payslip (bulletin de paie) is the central document of 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 model 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 orders. We will cover each zone of the payslip, the mandatory entries, the calculation of the MNS, the withholding tax (prélèvement à la source – PAS) section, and record-keeping obligations.

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

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

Employer Identification Zone

This zone must include:

• The employer’s name and address, or the establishment’s business name and address
• The establishment’s SIRET number
• The APE code (principal activity carried out)
• The reference of the body to which the employer pays social security contributions (the competent URSSAF)
• 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 automatically fills in this information from the company’s initial setup. However, it is advisable to verify its accuracy regularly, particularly in the event of a change of address, APE code or collective bargaining agreement.

Employee Identification Zone

The information relating to the employee includes:

• The employee’s surname and first name
• The position held and the contractual classification (level, step, coefficient)
• The period and number of working hours to which the remuneration relates, distinguishing between hours at the standard rate and overtime hours (with the applicable increase rate stated)
• The nature of the basis for calculating pay where this is not working time

Gross Remuneration Zone

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

• 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 increase rate
• Salary maintenance during absence (sickness, maternity, etc.)
• Paid leave allowance

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

The Social Contributions Zone

The simplified payslip, whose provisional model has been extended until 31 December 2026, groups contributions into major blocks to make them easier to read. The contribution lines must show:

Employee and Employer Contributions

The payslip must indicate, for each contribution or group of contributions:

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

The major blocks of the simplified payslip are as follows:

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

The Social Security Ceiling

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

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

The Net Social Amount (MNS): A Mandatory Entry Since 2024

Introduced by the order of 31 January 2023 and made mandatory on all payslips since 1 January 2024, the net social amount is an essential figure for employees, in particular for procedures with the CAF (family benefits 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 the gross remuneration for the MNS calculation include:

• Base salary
• Bonuses (seniority, 13th month, performance, etc.)
• Benefits in kind (food, housing, vehicle, IT/communications)
• 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 elements:

• 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 (PAS)

Net Pay Before Income Tax

The net pay before PAS corresponds to the amount the employee would receive if there were no tax withholding. 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 recalls 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 Model: Extended Until 31 December 2026

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

The main advantages of this model are:

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

Payroll software vendors have integrated this model into their solutions. It is nonetheless advisable to check the compliance of payslip templates regularly, particularly during annual configuration updates.

Payslip Record-Keeping: 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 storage may be carried out 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 safe (coffre-fort numérique).

Points requiring attention:

• 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 without any time limit
• Failure to issue the payslip is punishable by a fine of €450 per missing payslip

The Most Common Mistakes to Avoid

Here are the errors we most frequently encounter during our payroll compliance audits:

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

Summary Table of Payslip Zones 2025

For a concise overview, here are the main zones of a compliant payslip:

• Header: employer and 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, record-keeping notice, net-entreprises portal notice

FAQ: Your Questions on the Compliant Payslip in 2026

Must the net social amount appear on the payslip even if the employee does not receive social benefits?

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 allows the employee to declare their income to the CAF or France Travail in a simplified way. 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 rate of 0%?

Yes, the tax section relating to withholding tax 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 there is no configuration error.

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 safe, 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 address possible labour court litigation, as the limitation period for salary claims is 3 years.

Is the simplified payslip model mandatory in 2026?

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

What penalties apply for a non-compliant payslip?

Failure to issue the payslip is punishable by a 3rd-class fine (€450) per missing payslip. A non-compliant payslip may also expose the employer to a contribution reassessment 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 erroneous payslip may lead to damages awarded to the employee for breach of the obligation to issue a compliant payslip.
