Complete Guide to Salary Management in 2026

Salary management is one of the most critical and highly regulated functions within a company. In 2026, it sits at the intersection of several major transformations: the generalisation of the electronic payslip, the growing importance of the DSN (Déclaration Sociale Nominative), the rise of integrated HR software and the progressive adoption of electronic signature for HR. This comprehensive guide presents all the rules, best practices and essential tools for managing payroll in a compliant, efficient and secure manner — whether you are an HR Director, payroll manager, accountant or SME manager.

The Legal Fundamentals of Salary Management

The Employment Contract and Salary Setting

It all starts with the employment contract. Remuneration must be set in compliance with several legal minimums: the SMIC (fixed at £11.88 gross/hour on 1 January 2026, following a 2.2% revaluation linked to inflation), the minimum rates defined by the applicable collective agreement, and the principle of equal remuneration between women and men imposed by the Professional Future Act of 2018 and reinforced by European Directive 2023/970 on pay transparency, whose implementation in France has been introduced gradually since 2025.

Any modification to the basic salary constitutes a substantial change to the employment contract and requires written agreement from the employee. In 2026, this agreement can legally be collected via an electronic signature solution in the workplace compliant with the eIDAS regulation, which considerably accelerates HR processes whilst guaranteeing traceability.

The Payslip: Mandatory Provisions and 2026 Format

Since the 2016 Labour Act, the simplified payslip is the legal standard. In 2026, mandatory information includes: the employer's details (business name, SIRET, URSSAF), the employee's details (job, classification, coefficient), the pay period, gross salary, details of employer and employee contributions grouped by risk (health, occupational accidents, pension, unemployment), taxable net, net pay before tax and net pay after withholding at source.

The electronic payslip is now the standard in companies with more than 50 employees. The employer can impose it without the employee's prior agreement since the 2018 ESSOC Act, provided that it guarantees permanent access to the document via a digital safe or a secure personal space. The legal retention period is 50 years or until the employee reaches age 75 (Article D. 3243-3 of the Labour Code).

The Déclaration Sociale Nominative (DSN) in 2026

The DSN is the single mandatory channel for declaring social data for all employers since 2017. In 2026, it covers monthly declaration of contributions, notification of events (sickness absence, contract termination, return to work), and flows to all organisations (URSSAF, pension funds, supplementary bodies, France Travail). Filing must take place no later than the 5th or 15th of the following month depending on company size, via the net-entreprises.fr portal. Any delay exposes the employer to penalties of €7.50 per employee per month of delay.

Salary Calculation: Variable Elements and Contributions

Basic Salary, Bonuses and Variable Elements

Gross salary comprises the basic salary plus variable elements: overtime (increased by 25% for the first 8 hours, then 50%), bonuses (seniority, 13th month, profit-sharing, employee share scheme), benefits in kind (vehicle, housing, meal vouchers), travel allowances. Each of these elements is subject to specific rules regarding social contribution liability. For example, meal vouchers are exempt from contributions up to the capped employer contribution of €7.18 per voucher in 2026.

Profit-sharing and employee share schemes benefit from advantageous tax and social treatment: they are exempt from social contributions (excluding CSG/CRDS) up to 75% of the PASS (Annual Social Security Ceiling) for employee share schemes, approximately £34,000 in 2026.

Withholding at Source and Tax Rate Management

Introduced in 2019, withholding at source (PAS) remains one of the most technically delicate responsibilities for payroll departments in 2026. The employer collects income tax from the employee by applying the rate transmitted by the DGFiP via the PASRAU flow, integrated in the DSN. In the absence of a personalised rate, the employer applies the neutral rate (official table). Any malfunction in collection or payment to the Public Treasury exposes the company to penalties of 5% of the sums due, increased to 40% in case of deliberate breach.

Employer and Employee Contributions: 2026 Rates

The total cost of an employee represents on average 1.42 times their gross salary for a non-managerial employee, and up to 1.55 times for a manager, after applying general reliefs on low salaries (Fillon reduction). These reliefs, calculated on remuneration below 1.6 SMIC, can represent up to 31.94 percentage points of employer contributions, representing a significant annual saving for SME employers. The 2025 reform of occupational accident and disease (AT/MP) contributions introduced enhanced individualisation of rates based on the company's actual claims history, accessible on net-entreprises.fr.

Digitisation and Payroll Management Tools

Payroll Software and HRIS Integration

In 2026, the payroll software market is structured around three major families: cloud SaaS solutions (Payfit, Silae, Sage, Cegid, ADP, Lucca), integrated ERPs (SAP HCM, Workday, Oracle HCM), and accounting firm solutions accessible in delegated mode. The choice depends on company size, the desired degree of autonomy and the complexity of the applicable collective agreement. An essential point of vigilance: regulatory updates. Contribution scales, ceilings and tax parameters change every year; outdated software is a source of URSSAF audit risk.

Integration between payroll software and other HR tools (time and attendance, expense claims, contracts) is today a differentiating factor. It reduces duplicate data entry and errors. In this context, the use of an AI-powered contract generator coupled with an electronic signature tool allows you to automate the contract → onboarding → payroll chain in a coherent and traceable manner.

Electronic Signature in the Payroll Cycle

Salary management generates many documents requiring a signature: salary amendments, exceptional bonuses, profit-sharing agreements, settlement agreements, final settlement statements. Traditionally handled in paper format with delays and loss risks, these documents are being massively dematerialised through electronic signature. According to the comprehensive guide to electronic signature, three levels of signature coexist under eIDAS: simple, advanced and qualified — each suited to a different level of risk and commitment.

For a salary amendment or settlement agreement, advanced electronic signature (AES) is generally sufficient and offers solid probative value. The time saving is considerable: according to available industry data, the signature cycle for an amendment goes from 5 to 7 days in paper mode to less than 24 hours in electronic mode. You can moreover precisely assess your potential gains thanks to the electronic signature ROI calculator.

Archiving and Retention of Payroll Documents

Archiving of payslips and associated documents is subject to strict legal retention periods. Payslips must be retained indefinitely (since the 2015 Rebsamen Act). Accounting records related to payroll: 10 years. Social declarations (URSSAF, pension): 3 years. The DSN itself: 5 years. For employers using a digital safe, the service provider must be certified NF 461 (AFNOR standard relating to electronic archiving systems) to guarantee the integrity, confidentiality and availability of documents over time. This certification determines the probative value of archives in case of dispute.

Controls, Audits and Risk Management in Payroll

URSSAF Audit: Preparing and Managing a Settlement

URSSAF has the right to audit the past 3 calendar years. In 2025, the average amount of adjustments following an audit was approximately £22,000 for companies with 10 to 49 employees, according to Acoss data. The most frequent grounds for adjustment: non-subjection of bonuses or benefits to contributions, incorrect application of general reliefs, non-compliance with professional expense treatment rules, failure to declare benefits in kind.

The best protection remains annual preventive audit: review of contribution bases, verification of collective agreement rates, control of relief calculations. The downloadable contract templates and compliance tools can also help structure solid and enforceable HR documentation.

Equal Pay and the Égapro Index

Since 2019, companies with 50 or more employees are required to publish their Professional Equality Index (the "Égapro Index") each year before 1 March. This index, scored out of 100 points, measures five indicators: the gender pay gap (40 points), the gap in individual pay increase rates (20 points), the gap in promotion rates for companies with more than 250 employees (15 points), the percentage of female employees given a pay rise after maternity leave (15 points) and the representation of women among the top 10 earners (10 points). A score below 75 requires the company to define corrective measures on penalty of sanctions reaching 1% of the payroll.

European Directive 2023/970 on pay transparency, currently being implemented, will significantly strengthen these obligations from 2026-2027 onwards: obligation to communicate salary ranges in job advertisements, employee rights to access information on pay levels by category, and annual report on pay gaps for companies with more than 100 employees.

Legal Framework Applicable to Salary Management

Salary management is part of a dense legal framework, combining employment law, social law and, for its digitised dimension, information technology law.

Labour Code: Articles L. 3241-1 to L. 3245-2 govern salary payment (form, frequency, limitation period). Article L. 3243-1 requires provision of a payslip with each payment. Article D. 3243-3 sets retention periods. Article L. 1221-1 recalls that any employment contract is subject to the rules of common contract law, in particular articles 1101 onwards of the Civil Code.

Probative Value of Dematerialised Documents: Article 1366 of the Civil Code states that "an electronic document has the same probative force as a paper document, provided that the person from whom it emanates can be duly identified and that it is established and retained in conditions that guarantee its integrity". Article 1367 regulates electronic signature as a means of reliable identification. These two articles form the basis of the lawfulness of electronic signature for HR documents.

eIDAS Regulation No 910/2014: This European regulation defines the framework for mutual recognition of digital identities and electronic signatures within the European Union. It distinguishes three levels of signature (simple, advanced, qualified) and sets the technical requirements applicable to each. Qualified electronic signature (QES), issued by a qualified trust service provider (QTSP) registered on the trust list, benefits from a legal presumption of equivalence to handwritten signature.

GDPR No 2016/679: Payroll data (salaries, contributions, family status, banking details) constitute personal data sensitive in terms of GDPR. Their processing must be based on a legal basis (Article 6), be subject to notification of individuals (Article 13), respect the data minimisation principle and be protected by appropriate security measures (Article 32). In the event of a payroll data breach, the DPO must notify the CNIL within 72 hours (Article 33). Transfers of data outside the EU (to a non-European software publisher, for example) must be governed by standard contractual clauses or an adequacy agreement.

NIS2 Directive (2022/2555): Transposed into French law by the Act of 26 December 2024, NIS2 extends cybersecurity obligations to a large number of entities, including HR and payroll software publishers qualified as "important" entities. It requires risk management, notification of significant incidents to ANSSI within 24 hours, and personal responsibility of management in case of breach. For HR managers using cloud tools, it is essential to verify that the service provider is NIS2 compliant.

ETSI Standards: ETSI standards EN 319 132 (XAdES), EN 319 122 (CAdES) and EN 319 162 (PAdES) define interoperable and time-stamped electronic signature formats, guaranteeing the long-term probative value of signed documents. Recourse to a service provider certified as compliant with these standards is an essential guarantee in a long-term document retention context.

Use Cases: Electronic Signature in Service of Payroll

Scenario 1 — An Industrial SME with 180 Employees Streamlines Salary Amendments

An industrial SME managing around 180 employees on permanent contracts conducts two salary revaluation campaigns each year (January and July). Before digitisation, each cycle involved printing, postal delivery or hand delivery, handwritten signature, and return of each amendment — a process that took 3 to 5 weeks, with a follow-up rate of 20 to 30% of employees who had not returned their signed copy within the deadline.

After implementing an advanced electronic signature solution integrated into their HRIS, the SME reduces this timeframe to less than 48 hours for 95% of amendments. The follow-up rate drops to less than 5%. Signed documents are automatically archived in the employee's digital safe. The HR department estimates a saving of 3 to 4 working days per campaign, approximately 60 to 80 hours annually recovered from low added-value tasks.

Scenario 2 — An Accounting Firm Managing Payroll for 85 SME/VSE Clients

An accounting firm of intermediate size manages payroll on an outsourced basis for a portfolio of 85 clients, representing around 1,200 payslips per month. The central issue: annual profit-sharing agreements, ratified settlement agreements and final settlement statements require bilateral signatures (employer + employee) that slowed down the processing cycle.

By integrating an electronic signature platform into their workflow, the firm reduces the average processing time for a settlement agreement file from 8 days to 2 days. Traceability is complete (time-stamping, audit trail, IP), which strengthens the firm's position in case of subsequent dispute. Clients benefit from a dedicated interface to sign from their smartphone, increasing customer satisfaction measured at +22 points on the firm's annual NPS survey.

Scenario 3 — A Distribution Group of 2,400 Employees Deploys the Égapro Index and Pay Transparency

A distribution group with around 2,400 employees spread across 34 sites must publish its Égapro Index before 1 March and is preparing compliance with European Directive 2023/970 on pay transparency. To do this, the HR Director centralises data extraction from her ERP, establishes comparable job categories and prepares regulatory reports.

Distribution of individual communications on salary ranges, a new obligation arising from the Directive, is managed via an integrated HR solution allowing electronic signature of acknowledgement receipts. This arrangement guarantees proof of delivery of information to each employee, an essential element in case of inspection by the labour inspectorate or litigation before the industrial tribunal. The processing time for this communications campaign is reduced by 60% compared to a paper mailing, with postage and printing costs saving estimated at several thousand pounds per year.

Conclusion

Salary management in 2026 is no longer simply about calculating payslips: it encompasses real-time regulatory compliance, mastery of digital tools, legal safeguarding of HR documents and equal pay. Between monthly DSN, withholding at source, new transparency obligations from European Directive 2023/970 and the generalisation of the electronic payslip, payroll teams face a growing compliance burden.

Electronic signature is one of the most effective levers for streamlining and securing this document cycle whilst reducing operational costs. Certyneo offers you an eIDAS-compliant electronic signature solution, designed for HR and payroll processes of French SMEs and mid-market companies.
