How to Produce a Compliant French Payslip in 2026: A Complete Guide for Employers

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 performance of the employment contract and 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 temporary simplified payslip model until 31 December 2026. For HR departments and payroll managers, mastering these obligations is essential to avoid employment tribunal (prud’hommes) disputes and URSSAF reassessments.

This complete guide takes you step by step through the preparation of a payslip that complies with the French Labour Code, the BOSS (Official Bulletin of Social Security, Bulletin Officiel de la Sécurité Sociale) and the applicable orders. We will address each section of the payslip, the mandatory items, the calculation of the MNS, the tax section relating to the pay-as-you-earn withholding tax (prélèvement à la source, PAS) and the 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 section dedicated to payslips, restates and clarifies these obligations. The essential items are as follows:

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 (main activity carried out)
• The reference of the body to which the employer pays its social security contributions (the relevant URSSAF)
• The applicable collective bargaining agreement (convention collective) or, failing that, a reference to the Labour Code for the provisions relating to paid leave and notice periods

In practice, most payroll software automatically populates this information from the company’s initial configuration. Nonetheless, 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 employee-related information includes:

• The employee’s surname and first name
• The position held and the classification under the collective agreement (level, grade, 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 increased rate stated)
• The nature of the basis for calculating the salary where this is not working time

Gross Remuneration Section

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

• The base salary
• Bonuses and gratuities (seniority bonus, 13th-month payment, performance bonus, etc.)
• Benefits in kind valued according to the applicable scales
• Overtime hours with their increased rate
• Continued salary payment in the event of absence (illness, maternity, etc.)
• The 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 car benefit in kind valued on a flat-rate basis at €350 will have gross remuneration of €4,025.

The Social Security Contributions Section

The simplified payslip, whose temporary model 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

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, provident insurance (prévoyance)
2. Workplace 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, PMSS) is set at €4,005. This ceiling determines the calculation of many contributions (capped basic pension, Agirc-Arrco band 1, etc.). It must be prorated in the case of part-time work or entry/exit during the month.

Example: For an employee working at 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 data for employees, notably for their dealings 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 payable by the employee

The items taken into account in gross remuneration for the calculation of the MNS include:

• The base salary
• Bonuses (seniority, 13th month, performance, etc.)
• Benefits in kind (food, accommodation, vehicle, ICT equipment)
• Continued salary payment during an absence (illness, maternity)
• Overtime and additional hours
• The paid leave allowance
• Social security daily allowances (IJSS) paid by subrogation

The items 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 (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 (PAS) 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, standard/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 amount of PAS 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 temporary simplified payslip model, introduced to make the payslip clearer for employees, has been extended until 31 December 2026. This model groups contributions into major 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 the risk covered
• Display of the total employer cost (optional but recommended)
• Native integration of the net social amount

Payroll software providers have integrated this model into their solutions. However, it is advisable to check regularly that payslip templates remain compliant, particularly during annual configuration updates.

Retention of Payslips: a Minimum Obligation of 5 Years

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 digital form, provided that 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 particular 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 an employment tribunal dispute, 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 Errors to Avoid

The following are the errors we most frequently identify during our payroll compliance audits:

1. Omission of the MNS: since 2024, this item is mandatory on all payslips. Its absence may give rise to a dispute with the employee.
2. PAS section missing when the amount is nil: the BOSS is categorical – 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 agreement: the IDCC and the name of the agreement must appear on each payslip.
5. Benefits in kind not valued: benefits in kind must be assessed and appear both in the gross amount and as a deduction from net pay.

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 amount, PAS, net pay
• Footer: annual cumulative totals, retention 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 item on all payslips since 1 January 2024, regardless of the employee’s profile. This obligation arises 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 appear 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 item allows the employee to verify that their rate is correctly applied and to ensure that 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 a digital 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 deal with potential employment tribunal disputes, since 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 temporary model has been extended until 31 December 2026. All payslips must comply with the presentation by contribution blocks defined by order. Payroll software providers integrate this model into their solutions, but it is the employer’s responsibility to check that its payslips are compliant.

What penalties apply for a non-compliant payslip?

Failure to deliver the payslip is punishable by a 3rd-class contravention (€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 items on the payslip. Finally, in the event of an employment tribunal dispute, an incorrect payslip may lead to damages awarded to the employee for breach of the obligation to deliver a compliant payslip.
