Employer HR & Payroll Obligations in France: 2026 SME Guide

Quick answer. In 2026, a French employer must combine a DPAE before every hire, a monthly DSN filing by the 5th or 15th of month M+1 depending on headcount, a compliant pay slip, a single personnel register, a DUERP risk-assessment document, a professional interview every 2 years with a 6-year review, and a collective health insurance plan funded at least 50 % by the employer. Obligations layer up at 11, 50 and 250 employees, and the 2026 PASS social security ceiling is €48,060 (monthly PMSS €4,005).

Together with VAT, HR-payroll is the function most exposed to inspections inside a company. URSSAF (French social contributions authority), the labour inspectorate, the occupational health service, France Travail (formerly Pôle emploi), AGIRC-ARRCO (supplementary pension) and the Caisse des dépôts (personal training account, CPF): seven different administrations may scrutinise an employer's social practices. For an SME between 1 and 50 employees without a dedicated HR director, the issue is not to absorb every text, but to identify what triggers an automatic adjustment versus what calls for a judgement call.

At Hayot Expertise, we serve about a hundred employers ranging from 1 to 150 employees. The three most expensive omissions we encounter remain consistent: no BDESE above 50 employees (criminal sanction and lever for the works council), a health insurance plan that does not match the ANI minimum basket (loss of tax deductibility and retroactive URSSAF reassessment), and 6-year professional interview not documented (€3,000 corrective contribution per employee, doubled if not paid). This guide maps the full perimeter for a French SME employer in 2026, flagging at each step the headcount threshold that activates the obligation.

Reference date: 17 May 2026.

The Pre-Employment Declaration (DPAE)#

The DPAE (formerly DUE) must reach URSSAF at the earliest 8 days before and at the latest in the instant before the position is taken up. It cascades automatically: registration with social security, AGIRC-ARRCO affiliation, occupational health service enrolment, opening of unemployment insurance rights. Failure to file a DPAE creates a presumption of concealed work (article L. 8221-3 of the Labour Code), with criminal sanctions up to €45,000 fine and 3 years' imprisonment for the individual employer.

Employment contract and mandatory clauses#

The open-ended contract (CDI) is the standard form (article L. 1221-2 of the Labour Code). The fixed-term contract (CDD) is strictly limited (exhaustive list of grounds, maximum duration, 10 % precarity allowance). Part-time contracts must be in writing or face automatic reclassification as full-time (settled case law).

Mandatory clauses to verify systematically:

• identity and addresses of the parties;
• job title, collective agreement classification and coefficient;
• gross remuneration (base plus contractual variables);
• working time and pattern (full-time, part-time, fixed-day forfait);
• place of work and any mobility clause;
• applicable collective agreement (state the IDCC reference);
• probation period and renewal conditions;
• for a CDD: precise reason, end date or term, name of the replaced employee where relevant.

Medical visit and registers#

The information and prevention visit (VIP) must take place within 3 months of taking up the position (before the position for employees exposed to particular risks: SIR). The single personnel register (article L. 1221-13 of the Labour Code) must be kept in each establishment and produced on request to the labour inspectorate or URSSAF — its absence is a 4th-class offence applied as many times as there are employees affected.

Since 2017, the Déclaration sociale nominative has been the single monthly mandatory flow replacing DADS, DUCS, Pôle emploi attestations and AT/MP declarations. It feeds URSSAF, AGIRC-ARRCO, the health insurance fund, France Travail and the French tax authority (withholding tax). The DSN technical specification v4.9 applies to payroll paid in 2026.

2026 deadlines#

DSN penalties for 2026#

Based on the 2026 PMSS = €4,005, URSSAF sanctions are:

• Non-filing of a DSN: 1.5 % of PMSS per employee per month of delay, i.e. €60.08 per employee per month.
• Inaccurate compensation data: 1 % of PMSS, i.e. €40.05 per employee.
• Other omissions or non-compliant nomenclature: one-third of 1 % of PMSS, i.e. €13.35 per employee.

From 2026, URSSAF may issue a substitution DSN of its own motion when anomalies persist despite reminders. This substitution leads to a lump-sum calculation of contributions that is generally unfavourable to the employer — hence the importance of fixing the file as soon as the first anomaly is flagged. For larger adjustments (incorporating a benefit in kind, regularising overtime), we recommend a voluntary correction on the next month's DSN rather than waiting for an inspection. Our URSSAF inspection guide details the right posture.

The pay slip must be delivered each time remuneration is paid. The simplified template has been mandatory since 2018. For a line-by-line reading, see our guide understanding a pay slip; for the new 2026 layout (net social amount and 2026 structure), read the new 2026 pay slip.

Non-negotiable mandatory items:

• employer identification (legal name, SIRET, NAF, URSSAF reference) and employee (name, position, classification, coefficient, employee matricule where used);
• pay period and number of hours worked (with overtime hours and applicable premia);
• gross amount, line-by-line breakdown of social contributions (employee and employer shares), net social amount, taxable income, withholding tax, net pay;
• paid leave acquired and taken, RTT days where applicable;
• annual cumulative totals.

The employer must keep the pay slip for 5 years, and the employee has permanent access to their slips through the mon.compteformation.gouv.fr digital safe as generalised by the Labour Act.

Every employee accrues 2.5 working days of paid leave per month of effective work, or 30 days (5 weeks) per year. For the full mechanism, see our dedicated article paid leave calculation.

Major change from the law of 22 April 2024 (alignment with EU law following the Court of Cassation rulings of 13 September 2023): employees on non-occupational sick leave now accrue 2 working days per month (capped at 24 days per year), and employees on work-related injury or illness leave accrue 2.5 days per month without a duration cap. Employers must check retroactivity (back to 1 December 2009) and must have sent written information to the affected employees. Many payroll engines had still not, by the end of 2025, integrated the retroactive calculation — a priority audit.

The paid-leave allowance is calculated using the more favourable of the two methods: salary maintenance or the tenth rule (1/10 of the gross remuneration of the reference period).

Headcount is calculated as the average over the calendar year (article L. 130-1 of the Social Security Code, from the Pacte law). A threshold triggers its obligations only after 5 consecutive calendar years above it — except for the CSE which is assessed over 12 consecutive months.

Mandatory collective health insurance (ANI 2013)#

The ANI of 11 January 2013 and Law no. 2013-504 of 14 June 2013 have made it mandatory, since 1 January 2016, to set up collective health insurance in every private-sector employer (associations included). The employer must:

• offer a contract that at least covers the ANI minimum basket of care (statutory co-payment, daily hospital allowance, dental at 125 % of social security base, optical lump sums every 2 years);
• fund at least 50 % of the premium (the applicable collective agreement may impose a higher rate, often the case in hospitality, construction, metallurgy);
• formalise the set-up by unilateral employer decision (DUE), referendum agreement or collective agreement;
• collect in writing the legal opt-out cases (CDD shorter than 12 months, apprentices with contribution above 10 % of pay, dependents already covered, employees on CMU-C);
• check that the contract is responsible and solidarity-based (otherwise tax deductibility and contribution exemption are lost).

The mandatory provident plan for managerial staff (minimum 1.50 % on the first social security bracket fully borne by the employer, article 7 of the cadres collective agreement) remains compulsory and is a recurring blind spot for companies not covered by a branch-level provident agreement.

Professional interview and the 6-year trap#

The professional interview (article L. 6315-1 of the Labour Code) is mandatory every 2 years and distinct from the annual performance review. Every 6 years, a summary review must verify that the employee has had the prescribed interviews, completed at least one non-mandatory training action and obtained a wage or career progression.

In companies of 50 employees or more, when two cumulative conditions are not met — missed interviews AND no non-mandatory training — the employer must credit a corrective top-up of €3,000 to the employee's CPF (personal training account). If the top-up is not paid after formal notice, the amount due to the Treasury is increased by 100 %, i.e. €6,000 per affected employee.

The employer must keep and store, either on paper or digitally:

1. Single personnel register (L. 1221-13): all employees, interns, temporary workers in chronological order.
2. DUERP — single document for the assessment of occupational risks (L. 4121-3); updated at least annually in companies of 11+ employees and uploaded to a national digital portal for 40-year retention (2021 Occupational Health Act).
3. Register of minor work-related injuries (with CARSAT authorisation).
4. Register of labour inspectorate observations (D. 4711-3).
5. Public health and environmental alert register (from 50 employees).
6. Internal regulations (mandatory at 50+ employees since the Pacte law, formerly 20).
7. BDESE from 50 employees (permanent access for the CSE).
8. Mandatory postings: labour inspectorate, occupational health and emergency contacts, collective work schedule, applicable collective agreement, gender pay equality, harassment, fire safety, ban on smoking and vaping.

The Law of 29 November 2023 on value-sharing requires companies with 11 to 49 employees that have generated a taxable net profit equal to at least 1 % of revenue for three consecutive years to set up at least one value-sharing scheme (intéressement, participation, employer match or PPV) — effective from 1 January 2025. Our SME profit-sharing setup guide reviews the best-suited formula for fewer than 50 employees.

First hire in a very small business. DPAE before the position starts; check eligibility for any "first hire" subsidy applicable to the sector; formalise the reference collective agreement (and the IDCC code to mention on the pay slip); activate an occupational health service. Our 12-point "first employee" checklist is shared systematically with our clients.

Apprenticeship. Specific social regime (employer exemption under conditions, pay as a percentage of the SMIC depending on age and year), DPAE still mandatory, DSN reporting, OPCO funding. The 2026 monthly gross SMIC is €1,801.80 for 35 hours.

Crossing the 50-employee threshold. A 12-month compliance period for internal regulations, extended CSE and BDESE; immediate effect on the FNAL contribution and statutory participation (from the 5th consecutive year above the threshold).

Fixed-day forfait (forfait jours). Strictly framed, mandatory collective agreement, formalised workload monitoring (numerous Cass. soc. rulings); a forfait jours arrangement that is poorly documented will be reclassified as a 35-hour full-time contract with backdated overtime claims.

Part-time employee. Written contract mandatory; failing this, an irrebuttable presumption of full time applies. For shifts between full and part time, see also our analysis in SASU vs EURL comparison for the executive's status and SASU social charges for the social-security reading.

The URSSAF prescription period is 3 years (article L. 244-3 of the Social Security Code), extended to 5 years for concealed work. Any inspection must follow the adversarial procedure strictly (observation letter, employer's response, reasoned decision); any irregularity opens a remedy before the amicable appeal committee (CRA) and then the social pole of the judicial court.

We were recently engaged by a 38-employee Paris architecture firm after they crossed the 50-employee threshold mid-year — with limited anticipation: no BDESE, outdated internal regulations, no profit-sharing agreement. Our diagnostic identified €180,000 of latent social risk (€3,000 corrective CPF top-up × 12 employees with six years' tenure without documented interviews, plus a potential health insurance reassessment, plus a formal BDESE sanction). We rolled out a 90-day compliance plan that reduced residual risk to under €15,000.

Across our payroll portfolio, three omissions generate 80 % of the reassessments we observe:

1. Missing or incomplete BDESE above 50 employees. The direct sanction is limited (€1,500), but the indirect lever is heavy: the CSE can block the mandatory consultations, trigger an expert mission funded by the employer (up to €50,000 net of tax), and pursue an obstruction offence (up to €7,500).
2. Health insurance plan not aligned with the ANI basket or not extended to all employees. URSSAF reassessment then reincludes the employer share in the social base for the past 3 years. For 30 employees with a €60 monthly employer contribution, the reassessment easily exceeds €60,000.
3. Untraceable 6-year professional interview. Even if it physically took place, without a written record signed by the employee, it is deemed not to have occurred in litigation.

Hayot Expertise advice. Do not treat HR-payroll compliance as an annual project. Set up a quarterly review structured around four blocks: DSN and carrier feedback, registers and postings, interviews and training, health insurance and provident plan. Appoint a single owner (internal or outsourced) — the cost of a specialised accounting firm is, over a 3-year horizon, systematically below the cost of a single average URSSAF reassessment.

The Hayot Expertise firm provides outsourced payroll management for SMEs from 1 to 150 employees, mainly in Paris and Île-de-France:

• monthly pay slips (all collective agreements);
• DSN filing within statutory deadlines and CRM monitoring;
• management of sick leave, work-related injuries, maternity, paternity, parental leave;
• preparation of end-of-contract documents (final settlement, France Travail certificate, work certificate);
• social optimisation advice (intéressement, PEE, PPV, health insurance, provident plan);
• pre-threshold-crossing social audit;
• assistance during URSSAF and labour inspectorate audits.

Our social and payroll service is run by a single referent collaborator for each file, under the supervision of Samuel HAYOT, chartered accountant member of the French Order. For structuring questions, see also Hayot Expertise Paris 8.

• In 2026, an SME employer must combine DPAE, monthly DSN, personnel register, DUERP, compliant pay slip, professional interview and ANI health insurance — every gap triggers a predictable sanction.
• Monthly DSN: 5th of month M+1 (50+ employees, non-deferred payroll) or 15th of month M+1; 2026 PMSS = €4,005, 2026 PASS = €48,060.
• Headcount tiers structure obligations: 11 (CSE, training), 50 (BDESE, internal regulations, statutory profit-sharing, sanctioned 6-year interview), 250 (consolidated gender equality index).
• The three most expensive omissions observed in practice: missing BDESE, health insurance not aligned with the ANI basket, untraceable 6-year professional interview.
• A combination of reliable DSN + quarterly social audit divides URSSAF reassessment risk by five over a 3-year horizon.
• Employee savings remain underused: intéressement, PPV, PEE and statutory profit-sharing can together pay up to €36,045 exempt per beneficiary per year.
