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

Introduction: Why a Compliant Payslip Matters

The payslip (bulletin de paie) is the central document in the working relationship between employer and employee. It reflects the performance of the employment contract, 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 takes you step by step through producing a payslip compliant with the provisions of the French Labour Code, the BOSS (Bulletin Officiel de la Sécurité Sociale – the official Social Security bulletin) and the applicable ministerial orders. We cover each section of the payslip, the mandatory items, the calculation of the MNS, the tax section relating to withholding tax at source (prélèvement à la source – PAS) and retention obligations.

Mandatory Payslip Items (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, 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 name and address
• The establishment’s SIRET number
• The APE code (main business activity)
• 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 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. 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 collective bargaining classification (level, grade, coefficient)
• The period and the number of working hours to which the remuneration relates, distinguishing between hours at the standard rate and overtime hours (with the applicable premium rate indicated)
• The nature of the basis for calculating pay where this is not working time

Gross Remuneration Section

Gross remuneration comprises 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 premium rate
• Continued pay during 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 on a flat-rate basis at €350 will have gross remuneration of €4,025.

The Social Contributions Section

The simplified payslip, whose provisional model has been extended until 31 December 2026, groups contributions into broad blocks to make the payslip 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:

1. Health: supplementary health insurance, provident cover (prévoyance)
2. Workplace accidents – Occupational illnesses
3. Retirement: capped and uncapped 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 numerous contributions (capped basic retirement, Agirc-Arrco band 1, etc.). It must be prorated in the case of part-time work or entry/departure 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, particularly for dealings with the CAF (family allowance fund) and France Travail (the public employment service).

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

• Base salary
• Bonuses (seniority, 13th month, performance, etc.)
• Benefits in kind (meals, accommodation, vehicle, IT/communications equipment)
• Continued pay during a period of leave (sickness, 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):

• Reimbursement 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

Let us 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 “Net social amount” (Montant net social).

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 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 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 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 recommended to check the compliance of payslip templates regularly, particularly during annual configuration updates.

Retention of Payslips: A Minimum Obligation of 5 Years

The employer is required to keep a duplicate of payslips for 5 years (Article L.3243-4 of the French Labour Code). This retention may be carried out in paper or electronic 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 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 + 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 identify 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 where the amount is nil: the BOSS is categorical — the section must appear even where the amount withheld is €0.
3. Incorrect proration of the social security ceiling: for part-time employees or entries/departures 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 every 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 the 2025 Payslip Sections

For an 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 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) 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 tax section relating to withholding tax at source 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 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 duplicate 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 delivered to the employee via a digital safe, the availability period is 50 years or until the employee reaches 75. It is advisable to keep payslips beyond 5 years to address any labour court litigation, since the limitation period in salary matters 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 ministerial 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 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 correspond to 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 deliver a compliant payslip.
