Overtime Exemptions in France 2026: Complete Employer’s Guide
Introduction: Why Mastering Overtime Exemptions Matters
Overtime hours (heures supplémentaires) are a key flexibility lever for companies operating in France. In 2026, the exemption scheme remains particularly attractive, both for employees and employers. However, its practical application in payroll raises numerous questions: which rate of employee contribution reduction applies? How is the employer flat-rate deduction calculated? How does it interact with other social charge reliefs? This complete guide, intended for payroll managers and HR directors, details each mechanism, drawing on the references of the French Social Security Official Bulletin (Bulletin Officiel de la Sécurité Sociale, or 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 at 12:00 a.m. to Sunday at midnight, unless a collective agreement provides for another period of seven consecutive days.
The annual overtime quota (contingent annuel) is set at 220 hours per employee, unless collective bargaining provisions state otherwise. Beyond this quota, a mandatory compensatory rest period is added to the wage increase. It is essential to clearly distinguish overtime hours (heures supplémentaires) from additional hours (heures complémentaires), the latter concerning exclusively part-time employees.
1.2 Applicable Increase Rates
In the absence of a collective agreement, the statutory increases are as follows:
- 25% for the first 8 weekly overtime hours (from the 36th to the 43rd hour);
- 50% for subsequent hours (from the 44th hour onwards).
A company or industry-wide agreement may set a different increase rate, but it may not fall below 10%. The increase forms the base on which the social and tax exemptions are then applied.
1.3 Regulatory Sources
The scheme is governed by Articles L.241-17 and L.241-18 of the French Social Security Code, as well as by the BOSS, section “Overtime and additional hours exemptions” (paragraphs 10 to 320). Employers are advised to consult the BOSS regularly at boss.gouv.fr to keep track of updates.
2. The Reduction of Employee Contributions
2.1 Principle of the Reduction
Overtime and additional hours give rise to a reduction in employee old-age insurance contributions. This reduction applies to the remuneration paid for these hours, including the increase. It benefits all private-sector employees, regardless of the company’s workforce size (BOSS, § 110 et seq.).
2.2 Calculating the Reduction Rate
The reduction rate equals the sum of the employee old-age insurance contribution rates actually 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% | Entire salary |
| Supplementary pension B1 (Agirc-Arrco) | 3.15% | Bracket 1 |
| Supplementary pension B2 (Agirc-Arrco) | 8.64% | Bracket 2 |
| CEG B1 | 0.86% | Bracket 1 |
| CEG B2 | 1.08% | Bracket 2 |
The reduction rate is capped at 11.31%. For an employee whose remuneration does not exceed the Social Security ceiling (€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, up to the limit of 11.31% (BOSS, § 150).
2.3 Worked Example of the Employee Reduction
Take the case of an employee paid €3,200 gross per month (below the PASS), working 4 overtime hours in the month at an hourly rate of €25:
- Remuneration for overtime hours: 4 × €25 × 1.25 = €125.00
- Applicable reduction rate: 11.31%
- Amount of the reduction: €125.00 × 11.31% = €14.14
The employee therefore benefits from a €14.14 reduction on their old-age employee contributions for that month.
3. The Employer Flat-Rate Deduction
3.1 Amounts and Workforce Thresholds
The employer may benefit from a flat-rate deduction on employer contributions for each overtime hour worked. The amount of this deduction depends on the company’s workforce size:
- €1.50 per overtime hour for companies with fewer than 20 employees;
- €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. The workforce is assessed according to standard rules (average annual headcount, Article L.130-1 of the French Social Security Code). The BOSS specifies at paragraphs 200 to 240 the methods for determining the workforce and the rules for crossing thresholds.
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 €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 an URSSAF audit (BOSS, § 250).
3.3 Worked Example of the Employer Deduction
A company with 15 employees employs a worker who performs 20 overtime hours in the month:
- Flat-rate deduction: 20 × €1.50 = €30.00
If that same company had 45 employees:
- Flat-rate deduction: 20 × €0.50 = €10.00
The deduction is offset against the employer’s Social Security contributions due on the employee’s entire remuneration, and not solely on the remuneration for overtime hours.
4. The Special Case of the Day-Based Fixed Rate (Forfait Jours)
4.1 Principle of the Deduction for Employees on a Forfait Jours
Employees under an annual day-based fixed-rate agreement (forfait en jours) are not subject to the statutory weekly working time of 35 hours. By definition, they cannot therefore perform overtime in the classic sense. However, when an employee on a forfait jours waives rest days beyond 218 days, these worked rest days give rise to a specific scheme (BOSS, § 270).
4.2 Amount of the Deduction
The employer flat-rate deduction is set at €3.50 per rest day waived by the employee. This deduction is also subject to the de minimis regime (€200,000 ceiling over 3 years) and to the same workforce conditions as the hourly deduction.
4.3 Practical Example
A manager on a 218-day forfait waives 10 rest days during the year, bringing their fixed rate to 228 days. The company (12 employees) benefits from a deduction of:
- 10 × €3.50 = €35.00
The wage 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 increase.
5. Combining with Other Charge Reliefs
5.1 Interaction with the General Contribution Reduction (Single Degressive General Reduction 2026)
The employer flat-rate deduction for overtime may be combined with the general reduction of employer contributions (Article L.241-13 of the French Social Security Code). In practice, the employer may simultaneously apply the general reduction to the entire remuneration and the flat-rate deduction to overtime hours (BOSS, § 290).
However, the remuneration for overtime and additional hours is taken into account when calculating the coefficient of the general reduction. This means that overtime hours, by increasing total remuneration, may lower the general reduction coefficient and therefore the amount of relief.
5.2 Interaction with Other Schemes
The employee reduction on overtime hours may be combined with all employer contribution exemption schemes (ZRR, ZFU, BER, hiring assistance, etc.). The BOSS specifies, however, that the employer flat-rate deduction may only be combined with the general reduction and not with zone-based or targeted exemptions (BOSS, § 300).
6. The Tax Exemption of Overtime
6.1 Exemption Ceiling
Remuneration received for overtime and additional hours is exempt from income tax up to a limit of €7,500 net per year. This ceiling is assessed per employee and per calendar year. It includes the wage increase and the remuneration for the hours themselves (Article 81 quater of the French General Tax Code).
6.2 Calculating the Net Exempt Amount
The net amount exempt from tax corresponds to the gross remuneration of overtime hours, less the employee contributions still due after applying the employee contribution reduction. Example:
- Gross monthly overtime remuneration: €500.00
- Remaining employee contributions (non-exempt CSG/CRDS, provident scheme, etc.): approximately €50.00
- Employee contribution reduction: €500 × 11.31% = €56.55
- Net exempt tax amount: €500.00 – €50.00 + €56.55 ≈ €506.55
Over the year, if the employee accumulates €6,000 net of exempt overtime, they remain below the €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 hours in the DSN (specific field S21.G00.52). The employee finds this amount pre-filled in their income tax return. If the €7,500 ceiling is exceeded, the excess is reintegrated into taxable income.
7. Additional Hours of Part-Time Employees
7.1 Eligibility for Exemptions
Additional hours (heures complémentaires) performed 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 a limit of €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 contractual duration) give rise to the employer deduction.
7.2 Increase for Additional Hours
Additional hours are increased by:
- 10% for hours performed within the limit of 1/10th of the contractual duration;
- 25% for hours performed beyond 1/10th and up to 1/3 of the contractual duration.
7.3 Worked Example
A part-time employee (28 hours/week) performs 3 additional hours during the week, at an hourly rate of €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 = €49.95
- Employee reduction: €49.95 × 11.31% = €5.65
8. DSN Processing and Points to Watch
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 the employer flat-rate deduction (CTP 004);
- Block S21.G00.81: net tax amount exempt for income tax.
8.2 Points to Watch for the Payroll Manager
Several points deserve particular attention:
- Compensatory rest in lieu: when overtime hours are fully compensated by rest, they do not give rise to the employee reduction or the employer deduction (BOSS, § 160).
- Therapeutic part-time work: hours performed beyond the reduced contractual duration for medical reasons are indeed eligible additional hours.
- Multi-employer employees: the €7,500 tax exemption ceiling is assessed globally, across all employers combined.
- URSSAF audit: the employer must be able to justify the number of overtime hours actually worked (time records, weekly tallies).

FAQ: Frequently Asked Questions on Overtime Exemptions
Are structural overtime hours provided for in the contract eligible for exemptions?
Yes. As soon as these hours are performed beyond the statutory duration of 35 hours and are paid with the corresponding increase, they give rise 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 hours (BOSS, § 120).
How should overtime be treated where working time is annualized?
Where working time is modulated or annualized, overtime hours are counted beyond 1,607 annual hours (or the limit set by the agreement). The exemptions apply at the time of the year-end reconciliation at the end of the reference period. Certain hours may also be identified during the period when they exceed a weekly upper 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 may only be combined with the general reduction of 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 performed by an apprentice give rise to the employee contribution reduction under the same conditions as for other employees. The employer flat-rate deduction is also applicable if the workforce conditions are met. However, for apprentices whose remuneration is below 50% of the minimum wage (SMIC), since employee contributions are already exempt, the reduction may have no effect (BOSS, § 180).
What happens if the €7,500 tax exemption ceiling is exceeded?
Where the net remuneration of overtime and additional hours exceeds €7,500 over the calendar year, the excess is reintegrated into 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.
