Accumulating hundreds of effective overtime hours (HSE) as a contractual public service agent sometimes means seeing a portion of your salary vanish without any impact on your retirement. The rule is clear, but little known: not all overtime hours contribute equally when it comes to future contributions.
The distribution of HSE between those that count towards contributions and those that do not leads to marked differences when calculating the pension. A shaky declaration, a risky management, and you can be sure to find significant discrepancies in rights at the time of retirement.

HSE: definition, regulatory framework, and specifics for retirement
We talk about HSE, effective overtime hours, mainly among public school teachers. Unlike HSA (annual overtime hours), these hours correspond to occasional tasks performed beyond the established weekly service. Article L212-5-1 of the Labor Code specifies that any overtime hour begins beyond the 35 weekly hours set by the Aubry law. The ceiling, unless otherwise agreed, is set at 220 hours each year. On the payroll side, the increase rises to 25% for the first eight hours, then to 50% thereafter, unless the agreement provides for better terms.
The game changes for civil servants. The retirement pension is based solely on the last gross index salary, excluding bonuses and allowances. The HSE are linked to complementary schemes. Until 2019, they entitled holders to the RAFP (Additional Retirement of Public Service). Since then, they no longer provide additional rights via the RAFP but remain subject to CSG and CRDS. For private sector employees, each overtime hour leads to contributions to the CNAV and complementary AGIRC-ARRCO funds. The result: a direct impact on the average annual salary and retirement points.

To understand the role of HSE in retirement, one must decipher the differences depending on whether one is a civil servant or a private sector employee. Different purposes, variable social contributions, diverging calculation methods: everything revolves around a central question, that of the actual consideration of each hour worked to build future rights.
What is the concrete impact of HSE on the calculation of your retirement rights?
To measure the real effect of HSE on retirement, one must first dissect the mechanics of the system. In the private sector, each overtime hour feeds into the average annual salary (SAM) on which the calculation of the basic pension is based. These hours, subject to social contributions, also allow for the accumulation of AGIRC-ARRCO points for complementary retirement. They broaden the income base taken into account and, in some cases, accelerate the validation of contributed quarters: four quarters per year, validated as soon as the remuneration threshold (1,782 € in 2025) is reached.
On the public service side, the logic diverges. The amount of the pension depends entirely on the last gross index salary, and the HSE do not weigh in. Since 2019, they no longer create additional rights via the RAFP, unlike what was previously the case. However, they remain subject to CSG and CRDS, without impacting the main pension, but they can still count for the additional retirement if they date from before 2019.
Here’s what this concretely implies depending on your status:
- Basic retirement: for private sector employees, each overtime hour increases the SAM and can allow for faster validation of quarters.
- Complementary retirement: these hours generate AGIRC-ARRCO points provided they are subject to contributions.
- Public service: marginal consideration, limited to additional retirement for HSE prior to 2019.
Each regime applies its own logic: in the private sector, HSE support retirement, while in the public service, their impact remains secondary, even symbolic.
Properly managing your HSE: compliance issues and financial consequences for your pension
Managing your effective overtime hours (HSE) requires precision and attention. Each hour worked beyond the official framework is not just a number on the payslip: it can weigh heavily on the trajectory of your pension. The administration and pension funds monitor the regularity of the accumulation of HSE with the texts, conventions, or agreements in force. Exceeding the usual annual ceiling, often 220 hours in the absence of a derogation, can lead to adjustments, or even to the non-consideration of certain hours for retirement rights.
The way in which social contributions are deducted makes all the difference. Only HSE subject to these taxes feed into the count of validated quarters and points for complementary retirement. A bonus or allowance not subject to contributions, regardless of its amount, remains outside the scope for the pension. Teachers and agents concerned by special regimes therefore have every interest in ensuring that each HSE hour appears on the payslip, with the appropriate deductions clearly visible.
To avoid unpleasant surprises, keep these verification points in mind:
- Respect the ceiling of authorized overtime hours each year, unless a collective agreement provides otherwise
- Check the mention of HSE on your payslip, as it serves as the basis for calculating retirement
- Differentiate between bonuses subject to contributions and those that do not open any rights
Staying within the rules protects against disputes and ensures that every hour worked will count when asserting your rights. Forgetting means losing a part of your retirement, and no one wants to discover too late that the account is not balanced.
