Hiring a first employee marks a decisive turning point for any company. It's the moment when the entrepreneurial adventure shifts: from a personal project to a social entity with legal responsibilities, reporting obligations and real costs to manage. Far from being a mere administrative formality, this step requires rigor, clarity and a fine understanding of the mechanisms that govern it. Between the DPAE, the employment contract, social contributions and the available aids, the path is littered with details that, if forgotten, can turn a promising project into a source of stress and penalties. This guide goes through these different layers, not as a checklist to be ticked off quickly, but as a true structure to be built with care.
đ Key points to remember : The DĂ©claration prĂ©alable Ă l'embauche (DPAE) must be completed before any start of work to avoid penalties that can reach âŹ1,095 per employee. A written employment contract is mandatory, whether it is a CDI, CDD or another form of engagement. Registration in the employee register, affiliation to the mandatory company health insurance (mutuelle), the occupational health visit and the calculation of employer contributions (around 45% of the gross salary) complete this administrative puzzle. Financial aids exist to ease the first hire, notably through employment or apprenticeship support schemes. Finally, each step must meet precise deadlines: DPAE 8 days before hiring, occupational health visit within 3 months, first online social declaration (DSN) at the time of the first payslip.
đïž Avant l'embauche : poser les fondations administratives
Hiring is like binding a book: before assembling the pages, you must prepare the frame, the materials and ensure that everything will fit together correctly. Before the arrival of the employee, several essential checks help secure the process and avoid unpleasant surprises.
The first step is to clarify your status as an employer. If you have never hired before, check that you are correctly registered with the competent organizations. Identify the collective agreement applicable to your sector of activity: it will define minimum wages, working conditions and the rights of future employees. Also prepare the basic elements: SIRET, code APE, and your companyâs data that will appear on each administrative document. This phase, although it may seem bureaucratic, lays the real foundations of your future relationship with the labour administration.
At the same time, check the candidate's right to work. If they are a national of a country outside the European Union, check their residence permit and work authorization at least 48 hours before hiring. Keep copies: in the event of a labour inspection, this vigilance will protect you from accusations of undeclared work.

đ La DPAE : la dĂ©claration qui sĂ©curise tout
The Déclaration préalable à l'embauche (DPAE), formerly called DUE, is the founding act of your employer relationship. It is a single document that must be filed before any start of work, never after. It automatically informs URSSAF, PÎle Emploi (now France Travail), occupational health services and the CPAM of your employee's arrival.
Omitting or delaying the DPAE exposes you to a flat fine of âŹ1,095 per employee, doubled in case of repeat offence. Worse still, if intent is established, you could be prosecuted for undeclared work, with criminal consequences. To avoid this trap, submit it at least 8 days before hiring, ideally via the online portal net-entreprises.fr, which generates an immediate acknowledgement of receipt.
The DPAE contains precise information: employer identity, employee identifiers (NIR, name, date of birth), date and time of starting work, type of contract, and occupational health service contact details. If you hire an apprentice, specific fields are added. Once properly filed, this declaration triggers a cascade of administrative processes that ease your administrative burden.
âïž Le contrat de travail : bien plus qu'une formalitĂ©
The written employment contract is not a luxury; it is a protection for both parties. Even when the law does not formally require it for a full-time CDI, drafting one is highly recommended. For CDDs and part-time work, it is mandatory. Without a written contract, a judge could reclassify a part-time contract as a full-time CDI, or contest the terms of the engagement.
Your contract must clearly specify: the identity of the parties, the role and professional classification, the workplace, working time and hours, the gross remuneration and its components, the start date, the duration of the probationary period and its renewal conditions, as well as the applicable collective agreement. Additional clauses (mobility, confidentiality, non-competition, teleworking) can be added if they correspond to the reality of the job.
To quickly generate legally compliant employment contracts, many online tools offer legally checked templates. The probationary period, whose durations vary depending on the type of contract (2 to 4 months for a CDI for workers, technicians or executives; 1 day per week for a short CDD), must be expressly stated. It is not added automatically: it must be stipulated in the contract and can be renewed only once, according to the rules of your collective agreement.
đ Les registres et affichages obligatoires : transparence et traçabilitĂ©
From your first hire, you are required to keep a single personnel register. This document, whether paper or digital (with guarantees of IT integrity), records the name and surname, nationality, date of birth, sex, job, qualification, start date, and, if applicable, the end date of each employee. If you hire a foreign employee, also note their work authorization. This register must be kept for 5 years after the departure of the last recorded employee.
At the same time, several notices become mandatory in your premises: working hours, safety instructions, contact details of the occupational health service manager, and employees' rights regarding leave and working time. These notices are not decorations: in the event of a labour inspection, their absence can be noted as a breach. They demonstrate a desire for transparency and facilitate communication between you and your staff.
đ La visite d'information et de prĂ©vention : une obligation mĂ©dicale modernisĂ©e
Since 2017, the classic pre-employment medical examination has given way to the information and prevention visit (VIP). This process aims to assess general health, inform about the risks related to the position and raise awareness of prevention measures. For the majority of hires, this visit must take place within 3 months after starting work. However, for high-risk situations â night work, exposure to hazardous chemical agents, work at height, ionising radiation â the visit must be organised before starting the job.
The VIP differs from the classic medical exam: it is not a full clinical examination, but rather an interview with a nurse or occupational physician who can direct the employee to enhanced follow-up if necessary. This change reflects an evolution in the understanding of prevention: it is no longer about verifying that the employee is “fit”, but about supporting them in a progressive prevention approach. For the entrepreneur, this visit also provides valuable documentation in the event of a later dispute concerning working conditions or the employee's health.
đŒ Les affiliations sociales : construire le socle de protection
Once the employee is hired, several affiliations are triggered automatically via the DĂ©claration Sociale Nominative (DSN). However, some require proactive action on your part. The mandatory company health insurance (mutuelle) is the best example: since 2016, every employer must offer a complementary health plan, with the employer funding at least 50% of the premium. The minimum guarantees must cover a “basket” defined by the ANI (National Interprofessional Agreement). Exemptions exist (very short CDD, employee already covered, beneficiary of CMU-C), but they must be documented.
Supplementary retirement is added automatically: all employees are affiliated to AGIRC-ARRCO, and contributions are deducted from the first payslip. Depending on your collective agreement, a supplementary provident scheme may also be mandatory, particularly for executives (minimum 1.5% of tranche A of the salary). These elements, although they increase the overall cost, offer the employee comprehensive social protection, often valued at recruitment.
𧟠Le calcul réel du coût employeur : bien plus que le salaire brut
An employee on the SMIC never costs only the SMIC. The actual employer cost is around 145% of the gross salary, the majority being composed of employer social contributions. These charges include URSSAF (around 30% of gross), supplementary retirement (around 12%), unemployment (around 4%), and the employer's share of the mutuelle (variable depending on the plan). In addition, depending on your activity, there may be payments for provident schemes, professional training, or approved joint collecting bodies (OPCA).
For an employee earning âŹ1,500 gross per month in 2026, the real cost to the company exceeds âŹ2,150 per month. This gap may seem steep, but financial aids reduce this initial burden. The first-hire aid, exemptions for apprentices or professionalization contracts, the “Emploi Franc” scheme for certain areas, or regional aids can reduce this bill by several hundred euros per year. Consult the aids available from official bodies to find out which apply to your situation.
đ Le premier bulletin de paie : lancer le cycle mensuellement
The first payslip triggers a cycle that will not stop until the employee leaves: each month, at a fixed time, you must produce a compliant payslip. This document must follow a precise structure: employer and employee identity, pay period, gross salary, breakdown of social contributions, tax withholdings (pay-as-you-earn), and net pay. Contribution rates must correspond to the activity and the employee's status (worker, employee, executive).
The first payslip also generates a DSN (DĂ©claration Sociale Nominative) which automatically informs URSSAF of the hire. This declaration replaces the former monthly declaration: everything goes through this single channel. An omission or error in the initial configuration of contributions can lead to retroactive demands several months later. For this reason, many small companies entrust this task to an accountant or a specialised payroll service, even for a single employee.
đŻ Les spĂ©cificitĂ©s selon le profil du salariĂ© recrutĂ©
Each profile introduces additional obligations. Hiring a minor (aged 16 or 17) imposes strict limits: reduced hours (maximum 35 hours per week), prohibition on certain dangerous work, parental authorization, and a mandatory medical visit before starting work. Hiring an apprentice requires a specific training contract (CERFA form), registration with the OPCO within 5 days, and the appointment of an apprenticeship supervisor. Hiring a non-EU foreign employee requires verification of the residence permit and work authorization, with deadlines to be strictly respected.
Each of these hires also opens access to specific aids: up to âŹ6,000 for apprenticeships, contribution exemptions for professional contracts or Emploi Franc contracts for certain priority groups. Tailored support for your profile can turn these obligations into budgetary opportunities.
đ La documentation Ă transmettre : informer le salariĂ© avec clartĂ©
The law requires the employer to hand over or display several documents. The signed employment contract (two copies, one for each party) must be provided on the day of hiring. The information notice regarding the mutuelle, the internal rules or welcome booklet, and a copy of the DPAE or the Attestation de Reconnaissance d'Employeur (ARE) must also be provided. The applicable collective agreement must be made available (displayed or easily accessible for consultation).
Since 2023, a European directive also requires that the employee be informed, within 7 days, of essential elements: identity of the parties, workplace, role, start date, duration of the probationary period, remuneration, and working time. This information can be communicated via the contract itself or a separate document. Meeting this deadline avoids potential disputes over the initial conditions of engagement.
đ Ăviter les erreurs : les piĂšges les plus courants
The labour inspectorate is well aware of recurring shortcomings. The first, and most costly, remains the absence of a DPAE: an immediate âŹ1,095 fine, even for a single omission. The second is the absence of a written contract for a CDD or part-time role: a judge will automatically reclassify it as a CDI, creating an obligation for retroactive salary payments. The third is forgetting an affiliation (mutuelle, supplementary retirement): the organisation will claim unpaid contributions with interest.
A fourth pitfall, often less visible, is not respecting deadlines: hiring an employee before filing the DPAE, or arranging the medical visit after the third month. Finally, many entrepreneurs forget to document exemptions (mutuelle, provident schemes): in the event of an inspection, the absence of proof that the employee was exempted can lead to recovery claims. To secure each step, consult URSSAF's resources, which offer up-to-date guides and free tools.
âïž La mise en place progressive : un apprentissage continu
Hiring a first employee is not a sprint, but a learning process that lasts the first few months. The first payslip can be a source of errors: incorrect rate settings, omitted deductions, inaccurate leave calculations. The first month of integration also reveals potential administrative oversights (incomplete displays, missing documents). Real security lies in training: learn the basic rules, consult official organisations, and do not hesitate to call on an accountant or a specialised consultancy firm.
Like in the work of a bookbinder, where each stitch must be neat for the book to last for years, every administrative detail matters for your employer relationship to be durable and serene. It is an initial investment in rigor that prevents later complications and creates a framework of trust with your employee, the foundation of any fruitful collaboration.
