Overtime Exemptions in France 2026: A Complete Guide for Employers
Introduction: Why Mastering Overtime Exemptions Matters
Overtime is an essential lever of flexibility for companies operating in France. In 2026, the exemption regime remains particularly advantageous, both for employees and for employers. However, its practical application in payroll raises many questions: which employee contribution reduction rate should be applied? How is the employer flat-rate deduction (déduction forfaitaire patronale) calculated? How does it interact with other social contribution reliefs? This complete guide, intended for payroll managers and HR directors, details each mechanism based 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 Calculation of Overtime
Overtime hours (heures supplémentaires) are hours worked beyond the statutory weekly working time of 35 hours, or beyond the duration deemed equivalent in certain sectors. Overtime is calculated per calendar week, from Monday 0:00 to Sunday 24:00, 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 rest compensation is added to the pay increase. It is essential to distinguish overtime hours from additional hours (heures complémentaires), the latter applying exclusively to 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-level or sector-level agreement may set a different increase rate, but it cannot fall below 10%. The pay increase forms the base on which the social and tax exemptions are then applied.
1.3 Regulatory Sources
The regime is governed by Articles L. 241-17 and L. 241-18 of the French Social Security Code, 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 keep up with updates.
2. The Employee Contribution Reduction
2.1 Principle of the Reduction
Overtime and additional hours give rise to a reduction of employee old-age insurance contributions. This reduction applies to the remuneration paid for those 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 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 insurance | 6.90% | Band 1 (up to 1 PASS) |
| Uncapped basic old-age insurance | 0.40% | Full salary |
| Supplementary pension Band 1 (Agirc-Arrco) | 3.15% | Band 1 |
| Supplementary pension Band 2 (Agirc-Arrco) | 8.64% | Band 2 |
| CEG Band 1 | 0.86% | Band 1 |
| CEG Band 2 | 1.08% | Band 2 |
The reduction rate is capped at 11.31%. For an employee whose remuneration does not exceed the social security ceiling (EUR 4,005 per month in 2026), the reduction rate will be the sum of the old-age contribution rates on Band 1, i.e. approximately 11.31%. For an employee whose remuneration exceeds the ceiling, the calculation is made on a pro rata basis of the relevant bases, within the limit of 11.31% (BOSS, § 150).
2.3 Worked Example of the Employee Reduction
Consider the case of an employee with a gross monthly salary of EUR 3,200 (below the PASS), working 4 overtime hours in the month at an hourly rate of EUR 25:
- Remuneration for the overtime hours: 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 or more employees do not benefit from this flat-rate deduction. Headcount is assessed under ordinary rules (average annual headcount, Article L. 130-1 of the French Social Security Code). The BOSS specifies, in paragraphs 200 to 240, the methods for determining headcount and the threshold-crossing rules.
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 employs a worker who performs 20 overtime hours in the month:
- Flat-rate deduction: 20 × EUR 1.50 = EUR 30.00
If the 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 on the entire remuneration of the employee concerned, not solely on the remuneration of the overtime hours.
4. The Special Case of the Day-Based Fixed Arrangement (Forfait Jours)
4.1 Principle of the Deduction for Employees Under a Forfait Jours
Employees under an annual day-based fixed working arrangement (forfait en jours sur l’année) are not subject to the statutory 35-hour weekly duration. By definition, they therefore cannot work overtime in the classic sense. However, where an employee under a forfait jours waives rest days beyond 218 days, those 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 EUR 3.50 per rest day waived by the employee. 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 during the year, raising their forfait 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 increase.
5. Combining With Other Social Contribution Reliefs
5.1 Interaction With the General Contribution Reduction (Single Degressive General Reduction 2026)
The employer flat-rate deduction for overtime is combinable 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 on the entire remuneration and the flat-rate deduction on overtime hours (BOSS, § 290).
However, the remuneration of overtime and additional hours is taken into account in calculating the coefficient of the general reduction. This means that overtime, by increasing total remuneration, may lower the general reduction coefficient and therefore the amount of the relief.
5.2 Interaction With Other Schemes
The employee reduction on overtime combines with all employer contribution exemption schemes (ZRR, ZFU, BER, hiring aid, etc.). The BOSS nonetheless specifies 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 Income Tax Exemption for Overtime
6.1 Exemption Ceiling
Remuneration received for 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).
6.2 Calculating the Net Exempt Amount
The net amount exempt from tax corresponds to the gross remuneration of overtime hours, reduced by the employee contributions still due after applying the employee contribution reduction. Example:
- Gross monthly overtime remuneration: EUR 500.00
- Remaining employee contributions (non-exempt CSG/CRDS, supplementary insurance, etc.): approximately EUR 50.00
- Employee contribution reduction: EUR 500 × 11.31% = EUR 56.55
- Net tax-exempt 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 (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 surplus is reincorporated into taxable income.
7. Additional Hours of Part-Time Employees
7.1 Eligibility for Exemptions
Additional hours (heures complémentaires) worked by part-time employees benefit from the same exemptions as the overtime of full-time employees (BOSS, § 130):
- Employee contribution reduction (same rate, capped at 11.31%);
- Income 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 contractual duration) give rise to the employer deduction.
7.2 Increase on Additional Hours
Additional hours are increased by:
- 10% for hours worked within the limit of one tenth of the contractual duration;
- 25% for hours worked beyond one tenth and up to one third of the contractual duration.
7.3 Worked Example
A part-time employee (28 hours/week) works 3 additional hours during the week, at an hourly rate of EUR 15:
- One tenth 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. DSN Processing and Points of Vigilance
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-exempt amount for income tax.
8.2 Points of Vigilance for the Payroll Manager
Several points warrant particular attention:
- Substitute compensatory rest: where 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: hours worked beyond the reduced contractual duration 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-clock records, weekly counts).

FAQ: Frequently Asked Questions on Overtime Exemptions
Are structural overtime hours provided for in the employment contract eligible for exemptions?
Yes. As soon as these hours are worked beyond the statutory 35-hour duration 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 contractually stipulated. The BOSS does not distinguish between occasional and structural overtime (BOSS, § 120).
How should overtime be treated in the case of annualised working time?
In the case of modulation or annualisation of working time, overtime is counted beyond 1,607 annual hours (or the limit set by the agreement). The exemptions apply at the time of adjustment at the end of the reference period. Some 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 may only be combined with the general reduction of employer contributions (single degressive general reduction). It does not combine 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 rise 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, since employee contributions are already exempt, the reduction may be moot (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 surplus is reincorporated 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.
