How to Create a Compliant Payslip in 2026: A Comprehensive Guide

Introduction: The Importance of a Compliant Payslip

The payslip is the central document of the employment relationship between the employer and the employee. It substantiates the executed employment contract, details the remuneration paid, and outlines the contributions deducted. In 2026, regulatory requirements have evolved further, particularly with the consolidation of the montant net social (MNS) (net social amount) and the extension of the provisional simplified payslip model until December 31, 2026. For Human Resources departments and payroll managers, mastering these obligations is vital to avoid labor disputes and URSSAF (French social security agency) audits.

This comprehensive guide will walk you through the creation of a payslip compliant with the provisions of the Labour Code, the BOSS (Bulletin Officiel de la Sécurité Sociale), and the current decrees. We will discuss each section of the payslip, mandatory mentions, the calculation of the MNS, the tax section related to withholding tax (PAS), and conservation obligations.

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

Article R.3243-1 of the Labour Code provides an exhaustive list of the mentions that must appear on the payslip. The BOSS, in its section dedicated to the payslip, reiterates and clarifies these obligations. Here are the essential elements:

Employer Identification Section

This section must include:

• The name and address of the employer or the name of the establishment and its address
• The SIRET number of the establishment
• The APE code (main activity exercised)
• The reference of the body to which the employer pays social security contributions (competent URSSAF)
• The applicable collective agreement or, failing that, the reference to the Labour Code regarding provisions related to paid leave and notice periods

In practice, most payroll software automatically fills in this information based on the initial configuration of the company. However, it is advisable to regularly check their accuracy, especially in case of changes in address, APE code, or collective agreement.

Employee Identification Section

The information regarding the employee should include:

• The name and surname of the employee
• The job occupied and the collective classification (level, step, coefficient)
• The period and number of hours of work to which the remuneration relates, distinguishing between normal rate hours and overtime (with mention of the applicable increase rate)
• The type of salary calculation base when not based on working hours

Gross Remuneration Section

Gross remuneration comprises all components of the salary. The BOSS specifies that the following must be distinctly stated:

• The basic salary
• Bonuses and rewards (seniority bonus, 13th month, performance bonus, etc.)
• Benefits in kind evaluated according to current rates
• Overtime hours with their increase rate
• Salary maintenance in case of absence (illness, maternity, etc.)
• The holiday pay indemnity

Concrete Example: An executive employee with a monthly basic salary of €3,500, a seniority bonus of €175, and a benefits-in-kind vehicle evaluated at €350 will have a gross remuneration of €4,025.

Social Contributions Section

The simplified payslip, with its provisional model extended until December 31, 2026, groups contributions into main blocks for easier reading. The contributions 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 employer rate
• The employee amount and employer amount

The main blocks of the simplified payslip are as follows:

1. Health: supplementary health, insurance
2. Work accidents – Occupational diseases
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: professional training, apprenticeship tax, etc.

Social Security Ceiling

In 2026, the monthly social security ceiling (PMSS) is set at €4,005. This ceiling affects the calculation of many contributions (capped basic retirement, Agirc-Arrco tranche 1, etc.). It must be prorated in case of part-time work or mid-month entry/exit.

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

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

Established by the decree of January 31, 2023 and made mandatory on all payslips since January 1, 2024, the net social amount is essential for employees, particularly for processes with the CAF (Caisse d’Allocations Familiales) and France Travail.

Definition and Calculation of MNS

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

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

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

• The basic salary
• Bonuses (seniority, 13th month, performance, etc.)
• Benefits in kind (meals, housing, vehicle, IT)
• Salary maintenance during a leave (illness, maternity)
• Overtime and additional hours
• Holiday pay indemnity
• Daily social security indemnities (IJSS) paid by subrogation

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

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

Numerical Example for Calculating MNS

Let’s take a non-executive employee with the following elements:

• Basic salary: €2,500
• Seniority bonus: €125
• Benefits in kind meals: €5.45 x 20 days = €109
• Transport reimbursement: €45 (excluded from MNS)

Gross remuneration for MNS: €2,500 + €125 + €109 = €2,734

Mandatory employee contributions: approximately 22% of €2,734 = €601.48

MNS = €2,734 – €601.48 = €2,132.52

This amount must appear on a dedicated line of the payslip, clearly identified under the title « 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 no tax was withheld. It is calculated as follows:

Net Pay Before PAS = Gross remuneration – Total employee contributions + Expense reimbursements – Benefits in kind (deducted)

The Tax Section Relating to Withholding Tax

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

• The base for PAS (taxable net income)
• The applicable rate (personalized rate, neutral rate, or individualized rate)
• The amount of PAS withheld

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

Net Pay to the Employee

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 December 31, 2026

The provisional simplified payslip model, introduced to clarify payslip reading for employees, has been extended until December 31, 2026. This model groups contributions into major categories and simplifies presentation while maintaining all mandatory mentions.

The main advantages of this model are:

• Improved 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 publishers have integrated this model into their solutions. It is, however, recommended to regularly verify the conformity of payslip templates, especially during annual configuration updates.

Conservation of the Payslip: 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 Labour Code). This preservation can be done in paper form or digitally, provided the integrity, availability, and confidentiality of the documents are guaranteed.

Since January 1, 2017, employers can provide payslips electronically, unless the employee opposes this. In this case, the employer must ensure the availability of the payslip for 50 years or until the employee turns 75, via a compliant digital safe.

Points of Caution:

• In case of an URSSAF audit, payslips must be produced for the audited period (usually 3 years + current year)
• In case of a labor dispute, the employee can present their payslips as evidence without time limitation
• Failure to provide a payslip is punishable by a fine of €450 for each missing payslip

Common Mistakes to Avoid

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

1. Omission of the MNS mention: since 2024, this mention is mandatory on all payslips. Its absence can lead to a dispute with the employee.
2. PAS section absent when the amount is zero: the BOSS is clear; this section must be included even if the withheld amount is €0.
3. Incorrect prorating of the SS ceiling: for part-time work or mid-month entry/exit, the ceiling must be adjusted.
4. Incorrect or missing collective agreement: the IDCC and title of the agreement must be included on each payslip.
5. Non-evaluated benefits in kind: benefits in kind must be evaluated and appear both in gross and deducted from the net.

Summary Table of Payslip Sections for 2025

For a concise view, here are the major sections of the compliant payslip:

• Header: employer + employee identification + period
• Body: detailed gross remuneration + contributions by block
• Summary: total gross, total employee contributions, MNS, taxable net, PAS, net pay
• Footer: annual totals, conservation mention, mention for net-entreprises portal

FAQ: Your Questions on 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) is a mandatory mention on all payslips since January 1, 2024, regardless of the employee’s profile. This requirement stems from the decree of January 31, 2023. The MNS enables the employee to declare their income to the CAF or France Travail more easily. Its absence from the payslip constitutes a failure to comply with the employer’s legal obligation.

Is the PAS section necessary if the employee has a rate of 0%?

Yes, the tax section related to withholding tax is mandatory even when the amounts are zero. The BOSS explicitly states this obligation. The payslip must indicate the base, the rate (even at 0%), and the amount (even at €0). This mention allows the employee to verify that their rate is correctly applied and to ensure there are no configuration errors.

For how long must the employer keep payslips?

The employer must keep a copy of payslips for at least 5 years in accordance with Article L.3243-4 of the Labour Code. In the case of a digital payslip provided to the employee via a secure digital vault, the duration of availability is 50 years or until the employee turns 75. It is advisable to retain payslips beyond 5 years to address potential labor disputes since the statute of limitations in wage matters is 3 years.

Is the simplified payslip model mandatory in 2026?

The simplified model has been mandatory since January 1, 2018, for all companies. The current provisional model is extended until December 31, 2026. All payslips must comply with the block presentation of contributions defined by decree. Payroll software publishers include this model in their solutions, but it is the employer’s responsibility to verify the conformity of their payslips.

What are the penalties for a non-compliant payslip?

Failure to provide the payslip is punishable by a third-class contravention (€450) per missing payslip. A non-compliant payslip may also expose the employer to a retrospective collection of contributions during an URSSAF audit if the declared bases do not match the elements on the payslip. Finally, in case of labor disputes, an erroneous payslip can lead to damages payable to the employee for failing to fulfill the obligation to provide a compliant payslip.
