How to Apply Overtime Exemptions in France in 2026: A Complete Employer Guide
Introduction: why mastering overtime exemptions matters
Overtime (heures supplémentaires) is a key flexibility lever for companies operating in France. In 2026, the exemption scheme remains particularly advantageous, both for employees and employers. Yet its implementation in payroll raises numerous questions: which employee contribution reduction rate applies? How is the employer flat-rate deduction calculated? How does it interact with other payroll-cost relief measures? This complete guide, intended for payroll managers and HR directors, details each mechanism by relying on the references of the Official Social Security Bulletin (Bulletin Officiel de la Sécurité Sociale, BOSS, boss.gouv.fr).
1. The legal framework for overtime in 2026
1.1 Definition and counting of overtime hours
Overtime hours are working hours performed beyond the statutory weekly working time of 35 hours, or beyond the duration deemed equivalent in certain sectors. Counting is carried out per calendar week, from Monday 0:00 to Sunday 24:00, unless a collective agreement provides for another seven-consecutive-day period.
The annual overtime quota (contingent annuel) is set at 220 hours per employee, unless collective agreement provisions state otherwise. Beyond this quota, a mandatory compensatory rest (contrepartie obligatoire en repos) is added to the pay increase. It is essential to clearly distinguish overtime hours from additional hours (heures complémentaires), the latter concerning exclusively part-time employees.
1.2 Applicable increased pay rates
In the absence of a collective agreement, the statutory pay increases are as follows:
- 25% for the first 8 weekly overtime hours (from the 36th to the 43rd hour);
- 50% for the following hours (from the 44th hour onwards).
A company or industry-wide collective agreement may set a different increase rate, but it may not fall below 10%. The pay increase forms the base on which the social and tax exemptions are subsequently applied.
1.3 Regulatory sources
The scheme is governed by Articles L. 241-17 and L. 241-18 of the French Social Security Code (Code de la sécurité sociale), as well as by the BOSS, section “Exemptions for overtime and additional hours” (paragraphs 10 to 320). Employers are encouraged to consult the BOSS regularly at boss.gouv.fr to follow updates.
2. The reduction in employee social contributions
2.1 Principle of the reduction
Overtime and additional hours give entitlement to a reduction in employee old-age insurance contributions. This reduction applies to the remuneration paid in respect of these hours, including the pay increase. It benefits all private-sector employees, regardless of the company’s headcount (BOSS, § 110 et seq.).
2.2 Calculating the reduction rate
The reduction rate is equal to the sum of the employee old-age insurance contribution rates effectively borne by the employee. In 2026, this rate breaks down as follows:
| Contribution | Employee rate | Base |
|---|---|---|
| Capped basic old-age | 6.90% | Bracket 1 (up to 1 PASS) |
| Uncapped basic old-age | 0.40% | Full salary |
| Supplementary pension T1 (Agirc-Arrco) | 3.15% | Bracket 1 |
| Supplementary pension T2 (Agirc-Arrco) | 8.64% | Bracket 2 |
| CEG T1 | 0.86% | Bracket 1 |
| CEG T2 | 1.08% | Bracket 2 |
The reduction rate is capped at 11.31%. For an employee whose remuneration does not exceed the social security ceiling (plafond de la Sécurité sociale, PASS — EUR 4,005 per month in 2026), the reduction rate will be the sum of the old-age contribution rates on bracket 1, i.e. approximately 11.31%. For an employee whose remuneration exceeds the ceiling, the calculation is made pro rata to the relevant bases, within the 11.31% limit (BOSS, § 150).
2.3 Worked example of the employee reduction
Consider the case of an employee paid EUR 3,200 gross per month (below the PASS), working 4 overtime hours in the month at an hourly rate of EUR 25:
- Overtime remuneration: 4 × EUR 25 × 1.25 = EUR 125.00
- Applicable reduction rate: 11.31%
- Amount of the reduction: EUR 125.00 × 11.31% = EUR 14.14
The employee therefore benefits from a reduction of EUR 14.14 on their old-age employee contributions for that month.
3. The employer flat-rate deduction
3.1 Amounts and headcount thresholds
The employer may benefit from a flat-rate deduction of employer contributions for each overtime hour worked. The amount of this deduction depends on the company’s headcount:
- EUR 1.50 per overtime hour for companies with fewer than 20 employees;
- EUR 0.50 per overtime hour for companies with 20 to 249 employees.
Companies with 250 employees or more do not benefit from this flat-rate deduction. Headcount is assessed according to ordinary-law rules (average annual headcount, Article L. 130-1 of the Social Security Code). The BOSS specifies in paragraphs 200 to 240 the methods for determining headcount and the rules for threshold crossing.
3.2 De minimis regime
The employer flat-rate deduction is subject to the European de minimis regulation. The company must not have received more than EUR 200,000 in de minimis aid over the last three fiscal years. The employer must be able to demonstrate compliance with this ceiling in the event of a URSSAF audit (BOSS, § 250).
3.3 Worked example of the employer deduction
A company with 15 employees has an employee who works 20 overtime hours in the month:
- Flat-rate deduction: 20 × EUR 1.50 = EUR 30.00
If this same company had 45 employees:
- Flat-rate deduction: 20 × EUR 0.50 = EUR 10.00
The deduction is offset against the employer social security contributions due in respect of the entire remuneration of the employee concerned, and not solely against the overtime remuneration.
4. The specific case of the day-based fixed rate (forfait jours)
4.1 Principle of the deduction for employees under a forfait jours
Employees under an annual day-based fixed-rate agreement (convention de forfait en jours) are not subject to the statutory weekly working time of 35 hours. By definition, they therefore cannot work overtime in the traditional sense. However, when an employee under a forfait jours waives rest days beyond 218 days, these waived worked rest days give entitlement to a specific scheme (BOSS, § 270).
4.2 Amount of the deduction
The employer flat-rate deduction is set at EUR 3.50 per rest day the employee has waived. This deduction is also subject to the de minimis regime (EUR 200,000 ceiling over 3 years) and to the same headcount conditions as the hourly deduction.
4.3 Practical example
A manager under a 218-day forfait waives 10 rest days in the year, raising their fixed rate to 228 days. The company (12 employees) benefits from a deduction of:
- 10 × EUR 3.50 = EUR 35.00
The pay increase for these worked rest days must be at least 10% (Article L. 3121-59 of the French Labour Code), or more if a collective agreement so provides. The employee contribution reduction also applies to this pay increase.
5. Combining with other payroll-cost relief measures
5.1 Interaction with the general contribution reduction (single degressive general reduction 2026)
The employer flat-rate deduction for overtime can be combined with the general reduction in employer contributions (réduction générale, Article L. 241-13 of the Social Security Code). In practice, the employer may simultaneously apply the general reduction on the entire remuneration and the flat-rate deduction on overtime hours (BOSS, § 290).
On the other hand, the remuneration of overtime and additional hours is taken into account in the calculation of the general reduction coefficient. This means that overtime, by increasing total remuneration, may decrease the general reduction coefficient and therefore the amount of the relief.
5.2 Interaction with other schemes
The employee reduction on overtime can be combined with all employer contribution exemption schemes (rural revitalisation zones — ZRR, urban free zones — ZFU, employment revitalisation areas — BER, hiring aid, etc.). The BOSS specifies, however, that the employer flat-rate deduction can only be combined with the general reduction and not with zone-based or targeted exemptions (BOSS, § 300).
6. The tax exemption for overtime
6.1 Exemption ceiling
Remuneration received in respect of overtime and additional hours is exempt from income tax up to a limit of EUR 7,500 net per year. This ceiling is assessed per employee and per calendar year. It includes the pay increase and the remuneration of the hours themselves (Article 81 quater of the French General Tax Code — CGI).
6.2 Calculating the net exempt amount
The amount exempt from income tax corresponds to the gross overtime remuneration, less the employee contributions still due after applying the employee contribution reduction. Example:
- Monthly gross overtime remuneration: EUR 500.00
- Remaining employee contributions (non-exempt CSG/CRDS, provident cover, etc.): approximately EUR 50.00
- Employee contribution reduction: EUR 500 × 11.31% = EUR 56.55
- Net exempt taxable amount: EUR 500.00 – EUR 50.00 + EUR 56.55 ≈ EUR 506.55
Over the year, if the employee accumulates EUR 6,000 net of exempt overtime, they remain below the EUR 7,500 ceiling and the entire amount is exempt from income tax.
6.3 Reporting obligations
The employer must report the amount of exempt overtime in the DSN (nominative social declaration — déclaration sociale nominative, specific field S21.G00.52). The employee finds this amount pre-filled in their income tax return. If the EUR 7,500 ceiling is exceeded, the excess is reinstated in taxable income.
7. Additional hours of part-time employees
7.1 Eligibility for exemptions
Additional hours worked by part-time employees benefit from the same exemptions as overtime hours of full-time employees (BOSS, § 130):
- Employee contribution reduction (same rate, capped at 11.31%);
- Tax exemption up to EUR 7,500 net per year.
However, the employer flat-rate deduction does not apply to additional hours. Only overtime hours (beyond 35 hours or the collectively agreed duration) give entitlement to the employer deduction.
7.2 Increased pay for additional hours
Additional hours carry a pay increase of:
- 10% for hours worked within the limit of 1/10th of the contractual working time;
- 25% for hours worked beyond 1/10th and up to 1/3 of the contractual working time.
7.3 Worked example
A part-time employee (28 hours/week) works 3 additional hours in the week, at an hourly rate of EUR 15:
- 1/10th of 28 h = 2.8 h → 2.8 h increased by 10% and 0.2 h increased by 25%
- Additional-hours remuneration: (2.8 × 15 × 1.10) + (0.2 × 15 × 1.25) = 46.20 + 3.75 = EUR 49.95
- Employee reduction: 49.95 × 11.31% = EUR 5.65
8. Handling in the DSN and points requiring attention
8.1 DSN reporting
In the DSN, overtime and additional hours must be reported with the following specific codes:
- Block S21.G00.51: remuneration with the type “overtime hours” or “additional hours”;
- Block S21.G00.52: amount of the employee reduction (CTP 003) and of the employer flat-rate deduction (CTP 004);
- Block S21.G00.81: net taxable amount exempt from income tax.
8.2 Points requiring attention for the payroll manager
Several points deserve particular attention:
- Compensatory rest in lieu (repos compensateur de remplacement): where overtime hours are fully compensated by rest, they do not give entitlement to the employee reduction or the employer deduction (BOSS, § 160).
- Therapeutic part-time work (temps partiel thérapeutique): hours worked beyond the contractual working time reduced for medical reasons are indeed eligible additional hours.
- Multi-employer employees: the EUR 7,500 tax exemption ceiling is assessed globally, across all employers.
- URSSAF audit: the employer must be able to justify the number of overtime hours actually worked (time records, weekly counts).

FAQ: frequently asked questions on overtime exemptions
Are structural overtime hours provided for in the contract eligible for exemptions?
Yes. Provided these hours are worked beyond the statutory 35-hour duration and are paid with the corresponding increase, they give entitlement to the employee contribution reduction and the employer flat-rate deduction, even if they are provided for contractually. The BOSS does not distinguish between occasional and structural overtime (BOSS, § 120).
How should overtime be handled where working time is annualised?
Where working time is modulated or annualised, overtime hours are counted beyond 1,607 annual hours (or beyond the limit set by the agreement). The exemptions apply at the time of the adjustment at the end of the reference period. Certain hours may also be identified during the period when they exceed an upper weekly limit set by the agreement (BOSS, § 140).
Can the employer flat-rate deduction be combined with ZRR or ZFU exemptions?
No. The employer flat-rate deduction for overtime can only be combined with the general reduction in employer contributions (single degressive general reduction). It cannot be combined with zone-based exemptions (ZRR, ZFU, BER) or with other targeted exemptions (BOSS, § 300). The employer must choose the most advantageous scheme.
Can an apprentice benefit from overtime exemptions?
Yes. Overtime hours worked by an apprentice give entitlement to the employee contribution reduction under the same conditions as for other employees. The employer flat-rate deduction is also applicable if the headcount conditions are met. However, for apprentices whose remuneration is below 50% of the SMIC (statutory minimum wage), since the employee contributions are already exempt, the reduction may be without object (BOSS, § 180).
What happens if the EUR 7,500 tax exemption ceiling is exceeded?
Where the net remuneration of overtime and additional hours exceeds EUR 7,500 over the calendar year, the excess is reinstated in the employee’s taxable income. The employer must adjust the amount reported in the DSN at year-end. The employee finds the correct amount on their pre-filled return. The social contribution exemptions are not affected by this tax ceiling; they continue to apply without any amount limitation.
