How to Issue a Compliant Payslip in France in 2026: A Complete Guide for Employers

Introduction: Why a Compliant Payslip Matters

The payslip (bulletin de paie) is the central document in the employment relationship between employer and employee. It gives concrete form to the executed employment contract, detailing 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, or 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 provisions of 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 section of the payslip, the mandatory items, the calculation of the MNS, the withholding-tax section (prélèvement à la source, or PAS), and retention obligations.

Mandatory Items 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 items that must appear on the payslip. The BOSS, in its dedicated payslip section, reiterates and clarifies these obligations. Here are the essential elements:

Employer Identification Section

This section must include:

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

In practice, most payroll software fills in this information automatically based on the company’s initial configuration. Nevertheless, its accuracy should be checked regularly, particularly in the event of a change of address, APE code, or collective bargaining agreement.

Employee Identification Section

The information relating to the employee includes:

• The employee’s first and last name
• The position held and the classification under the collective agreement (level, grade, coefficient)
• The period and number of hours of work to which the remuneration relates, distinguishing between hours at the standard rate and overtime hours (indicating the applicable premium rate)
• The nature of the basis for calculating pay where this is not working time

Gross Remuneration Section

Gross remuneration comprises all the components of pay. The BOSS specifies that the following must appear separately:

• Base salary
• Bonuses and gratuities (seniority bonus, 13th month, performance bonus, etc.)
• Benefits in kind assessed according to the applicable scales
• Overtime hours with their premium rate
• Continued pay during absence (illness, maternity, etc.)
• Paid-leave allowance

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

The Social Security Contributions Section

The simplified payslip, whose provisional model is 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 main blocks of the simplified payslip are as follows:

1. Health: supplementary health cover, protection insurance (prévoyance)
2. Occupational accidents – Occupational illnesses
3. Retirement: capped and uncapped basic social security, supplementary (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, or PMSS) is set at €4,005. This ceiling governs the calculation of many contributions (capped basic retirement, Agirc-Arrco tranche 1, etc.). It must be prorated in the case 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.

The Net Social Amount (MNS): A Mandatory Item 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 essential information for employees, particularly for 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 and levies payable by the employee

The elements included in gross remuneration for the calculation of the MNS are:

• Base salary
• Bonuses (seniority, 13th month, performance, etc.)
• Benefits in kind (food, housing, vehicle, ICT)
• Continued pay during a leave of absence (illness, maternity)
• Overtime and additional hours
• Paid-leave allowance
• Social security daily allowances (IJSS) paid by subrogation

The elements not included (excluded from gross remuneration for the MNS) are:

• 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

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 reminds employers that the withholding-tax (PAS) section 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 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 Due to the Employee

Final net pay is calculated as follows:

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 the payslip clearer for employees, has been extended until 31 December 2026. This model groups contributions into broad categories and simplifies the presentation while retaining all mandatory items.

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 nevertheless advisable to check the compliance of payslip templates 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 may be done in paper or dematerialised form, provided that the integrity, availability, and confidentiality of the documents are guaranteed.

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

Points to watch:

• 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 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 observe during our payroll compliance audits:

1. Omission of the MNS: since 2024, this item has been 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 clear—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 name 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 pay.

Summary Table of Payslip Sections

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, PAS, net pay
• Footer: annual cumulative totals, retention notice, net-entreprises portal notice

FAQ: Your Questions About Compliant Payslips 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) has been a mandatory item 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.

Must the PAS section be shown if the employee has a rate of 0%?

Yes, the withholding-tax section is mandatory even where the amounts are nil. The BOSS explicitly sets out this obligation. The payslip must indicate the base, the rate (even at 0%), and the amount (even at €0). This item allows the employee to verify that the correct rate is being applied and to ensure that 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 a dematerialised payslip is delivered to the employee via a digital vault, the period of availability is 50 years or until the employee reaches the age of 75. It is advisable to keep payslips beyond 5 years to address any labour court litigation, given that the limitation period for salary-related 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 is the employer’s responsibility to verify the compliance of its payslips.

What are the penalties 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 erroneous payslip may result in damages awarded to the employee for breach of the obligation to deliver a compliant payslip.
