The legal workweek in France is 35 hours. Any hour worked beyond that counts as overtime. Under the default rules, overtime pay in France is calculated at 25% extra pay for hours 36 through 43 each week. Hours beyond the 43rd get a 50% premium. A collective bargaining agreement can set a different rate, but it can never go below 10%. That is the short answer. The rest of this guide covers what actually trips up HR teams: exemptions, annual limits, tax treatment, and the math itself.
What Counts as Overtime Under French Law?
Overtime only applies to hours the employer asked for or accepted. An employee cannot decide to stay late on their own and claim extra pay. The request can be explicit or implied, for example, when a manager approves a workload that cannot be finished in 35 hours. Not every hour at the office counts as worked time. French law uses the term “temps de travail effectif” to define the hours that count toward the 35-hour threshold.
A lunch break does not count unless the employee stays available for work. Commute time does not count either, except for travel between two job sites during the same shift. Some on-call periods count, and some do not, depending on how much freedom the employee has during that time. It helps to separate overtime from a related but different concept: heures complémentaires.
This term applies only to part-time employees. If someone has a 25-hour weekly contract but works 28 hours, they complete those 3 extra hours as heures complémentaires, not heures supplémentaires. The pay rules differ. Heures complémentaires generally get a smaller premium and follow a separate legal ceiling tied to the employment contract. Mixing up these two terms is one of the most common payroll errors in small companies without a dedicated HR function.
The Legal Overtime Rates
Once you confirm an hour qualifies as overtime, the next step is applying the correct rate. The Code du travail sets a default structure for the standard 35-hour workweek. Hours 36 through 43 each week earn a 25% pay increase. Every hour after the 43rd earns a 50% increase. These rates apply automatically unless a collective agreement says otherwise.
Many companies fall under a convention collective that changes these numbers. The law allows this, as long as the negotiated rate does not drop below 10%. Some sectors negotiate a flat premium that starts from the very first overtime hour instead of using the 25/50 split. Others keep the legal default but change how they measure the weekly count, such as by using a monthly or annual reference period instead of a strict calendar week.
| Overtime Range | Legal Default Rate |
| Hours 36 to 43 Per Week | 25% |
| Hours Beyond the 43rd Per Week | 50% |
| Under a Convention Collective | Minimum 10%, can be higher |
Because these figures shift by sector and by year, always check the specific convention collective that applies to your company before running payroll. Do not assume the legal default applies just because it is the most common baseline.
Here is a Simple Example:
An employee earns 15 euros an hour and works 40 hours in one week. That is 5 overtime hours, all falling in the 25% bracket. The extra pay is 5 hours times 15 euros times 1.25, which equals 93.75 euros on top of the standard 35-hour salary. If that same employee worked 45 hours, the calculation splits into two brackets: 8 hours at 25% and 2 hours at 50%.
The Annual Overtime Contingent
French law also caps how much overtime an employee can work across a full year. This cap is called the contingent annuel. The default figure set by decree is 220 hours per year, though a convention collective can raise or lower it.
This number matters because it changes what happens next. Overtime worked within the contingent only triggers the pay premium described above. Overtime worked beyond the contingent triggers an additional obligation called the contrepartie obligatoire en repos, or mandatory rest compensation. This is separate from any voluntary time off arrangement and cannot be skipped once the threshold is crossed.
Before an employee approaches this yearly limit, the employer should consult the CSE, the staff representative body, if one exists in the company. Ignoring this step exposes the employer to legal risks, even if the employer calculates the extra pay correctly. Tracking hours against the annual contingent is one area where a simple spreadsheet error can snowball into a compliance issue months later, so building a habit of monthly tracking rather than a year-end scramble saves real trouble.
Who is Exempt: The Forfait-Jours Exception
Not every employee accrues overtime the same way. Certain cadres, meaning autonomous managerial staff, can be placed under a forfait-jours agreement instead of a standard hourly schedule. Under this arrangement, the employee’s workload is measured in days per year rather than hours per week, commonly 218 days. This distinction confuses many HR teams. A cadre under forfait-jours does not receive extra pay for working more than 35 hours in a given week. The trade-off comes with different protections, including a maximum number of working days, mandatory rest periods, and an annual review of workload with the employer.
Not every manager qualifies for this status automatically. The employee needs real autonomy over their schedule, and the employer must document the arrangement in an individual agreement supported by a valid collective bargaining framework. Placing someone under forfait-jours without meeting these conditions is a common misclassification risk. If challenged, the company can end up owing years of unpaid overtime under the standard rules, plus penalties. This is worth flagging clearly to any manager who assumes forfait-jours is just a label for salaried staff.
Cash Payment vs Compensatory Rest
Employers do not always have to pay overtime in cash. French law allows overtime to be converted into paid time off instead, through a mechanism called repos compensateur de remplacement, often shortened to RCR. Whether this option is available depends on the company’s agreement or the applicable convention collective. Some sectors let the employer choose freely between cash and time off. Others require employee agreement before switching to RCR, or restrict it to hours above a certain threshold.
The conversion itself follows the same premium logic as cash pay. An hour paid at 125% converts to 1 hour and 15 minutes of rest, not a flat 1 hour. Getting this wrong undercounts the time owed to the employee, which creates the same kind of liability as underpaying overtime in cash. Any company using RCR should document the conversion clearly on the payslip or in a separate tracking sheet, since this is one of the areas tax authorities and labor inspectors check closely during an audit.
Tax and Social Security Treatment of Overtime Pay
Overtime pay in France gets favorable tax treatment compared to regular salary. Employees benefit from an income tax exemption on overtime earnings up to an annual cap, and a reduction in employee-side social security contributions applied to that portion of pay. These figures change periodically through finance law updates, so verify any specific euro amount against the current year’s official text before publishing or applying it in payroll.
For HR purposes, the key point is that tax authorities treat overtime pay differently from base salary, so employers should show it clearly as a separate line item on the payslip. This separation also helps when explaining a payslip to an employee. Many workers notice their overtime hours are taxed less than expected and assume a payroll error. Knowing the underlying rule lets HR answer that question in one sentence instead of escalating it as a dispute.
How to Calculate Overtime Pay in France: Step-by-Step
Here is the full process from start to finish, using a single worked example. Start with the employee’s base hourly rate. Divide the monthly salary by the monthly legal hours, typically around 151.67 for a standard 35-hour week. For a salary of 2,500 euros, that gives an hourly rate of about 16.48 euros. Next, count the actual hours worked that week and subtract 35. If the employee worked 42 hours, that leaves 7 overtime hours. Apply the correct bracket to each hour. In this example, hours 36 through 42 fall entirely within the 25% bracket, since the 50% bracket only starts at hour 44.
So all 7 hours get the 25% premium. The extra pay is 7 times 16.48 times 1.25, which comes out to roughly 144.20 euros. If the same employee worked 46 hours instead, the calculation splits. Hours 36 through 43 get 25%, and hours 44 through 46 get 50%. Add both amounts together for the total overtime pay owed that week. Doing this by hand across dozens of employees invites errors, especially once a convention collective changes the standard rates or the contingent annual comes into play. Running the numbers through a dedicated calculette mauricette catches these edge cases automatically and keeps calculations consistent across your payroll cycle.
Common Mistakes HR Teams Make
A few errors show up again and again in French payroll practice. Knowing them in advance saves time and avoids costly corrections later. The first is citing the wrong article of the Code du travail when documenting an internal overtime policy. This mistake spreads easily because people copy one incorrect source from another, undermining an otherwise solid policy document during an audit.The second mistake confuses heures complémentaires with heures supplémentaires, causing employers to apply the wrong premium to part-time staff.
The third is defaulting to the legal minimum rate without checking whether the applicable convention collective requires more. This is one of the most expensive mistakes, since it can mean underpaying every overtime hour worked at the company for months. The fourth is losing track of the annual contingent and missing the mandatory rest compensation once an employee crosses it. This obligation stands independently of overtime pay, and employers cannot replace it with extra cash.
Final Thoughts
Calculating overtime pay in France correctly comes down to getting three things right: the applicable rate, the annual contingent, and any exemptions that apply to specific employees. Skipping any one of these creates real financial and legal risk for the company. Building these checks into a repeatable monthly process, rather than treating overtime as an afterthought at the end of the pay cycle, separates a smooth payroll run from a costly correction six months down the line.
Frequently Asked Questions (FAQs)

Q2. Do all employees get paid overtime in France?
Answer: No. Employees under a forfait-jours agreement, typically autonomous managers, follow a different system based on working days rather than weekly hours.
Q3. How many overtime hours can an employer require per year?
Answer: The default annual limit, called the contingent annuel, is 220 hours, though this can change under a convention collective.
Q4. Is overtime pay taxed in France?
Answer: Overtime earnings benefit from a partial income tax exemption and reduced employee social security contributions, up to a yearly cap set by finance law.
Q5. Can overtime be replaced with time off instead of pay?
Answer: Yes, through a mechanism called repos compensateur de remplacement, if the company agreement or convention collective allows it.
