On a a pay slip from the hospital public service, a line often appears without us always knowing what it covers: the special duty allowance, abbreviated as ISS. This bonus compensates for specific constraints related to the daily practice of certain professions. It does not apply to all agents, and its calculation follows rules that regulatory texts have evolved over recent years.
Why the ISS is not just a single bonus
We often refer to “the special duty allowance” as a unique system. In practice, several duty regimes coexist depending on the branches of the public service. The ISS provided by the decree of August 1, 1990, targets the hospital public service. Territorial psychologists fall under another system, the IRSSP. Some territorial drivers receive the IRSSTS.

Each regime has its own calculation rules, beneficiaries, and accumulation conditions. Grouping everything under the label “duty bonus” gives a misleading view. A hospital agent and a territorial psychologist do not receive the same thing, and the texts that establish their allowances have nothing in common.
This distinction has a concrete impact on remuneration. The IRSSTS, for example, is not cumulative with the IHTS or the IAT, which alters the agent’s actual net gain. Therefore, before checking an amount, it is necessary to identify the correct regime applicable to one’s body and branch. To learn more about the special duty allowance, it is useful to refer to the decree that corresponds to one’s situation.

Agents eligible for the hospital special duty allowance
The decree of August 1, 1990, sets the initial framework. Civil servants, trainees, and contractual staff can claim the ISS under certain conditions. The decree of October 29, 2021, redefined the scope of beneficiaries by precisely listing the relevant bodies.
Here are the main categories targeted by this text:
- Nursing staff governed by the decree of November 30, 1988, as well as general and specialized care nurses governed by the decree of September 29, 2010.
- Health executives governed by the decree of December 31, 2001, who supervise care teams on a daily basis.
- Advanced practice medical auxiliaries, more recently integrated into the system to account for the evolution of the medico-social field.
The scope of beneficiaries continues to expand over the course of reforms. The addition of advanced practice medical auxiliaries shows that the regulations are adapting to new professions and the constraints they share with historically covered bodies.
Calculation of the ISS: base, rate, and impact on the pay slip
Are you wondering how the amount appears on your pay slip? The hospital ISS is calculated as a percentage applied to the gross salary of the agent. This percentage is set by regulatory texts and does not depend on local negotiation.
The gross salary taken into account corresponds to the indexed index held by the agent. The allowance therefore follows index changes: a change in step or grade mechanically alters the amount received. It is paid monthly and appears on the pay slip alongside other elements of the allowance regime.
What the ISS does not cover
The ISS compensates for the duties related to hospital practice (shift hours, physical constraints, constant contact with patients). It does not replace bonuses related to specific risks such as the unsanitary bonus or the critical care bonus. These bonuses can be combined with the ISS, but each responds to a distinct triggering event.
Confusing the ISS with the entirety of the hospital allowance regime is a common mistake. A night nursing assistant will receive the ISS for their general duties, and distinct increases for night work.
Territorial public service: the role of local deliberation
In the territorial public service, the situation differs on a major point. Some duty regimes are optional and depend on a deliberation by the deliberative body of the community. One municipality may decide to grant the allowance, while another may not, for agents holding comparable positions.
This local flexibility creates significant salary disparities between territories. A territorial agent who changes communities may lose a duty allowance they previously received, with no recourse possible since the allocation was based on a decision by the public employer.
Amounts sometimes frozen for a long time
Another peculiarity that weighs on purchasing power: some reference amounts have not changed for years. The IRSSP for psychologists, for example, is based on reference amounts unchanged since January 1, 2006. The constraints of the profession have evolved, but the calculation base has not.
This prolonged freeze raises the question of the adequacy between financial compensation and the reality of the duties endured. Revaluations, when they occur, go through new decrees, a slow process that sometimes leaves agents waiting for several years.
Allocation of the ISS: concrete points of vigilance
Some practical guidelines are worth keeping in mind to check one’s situation:
- Identify the applicable decree for one’s body and branch of the public service before any comparison with a colleague from another department.
- Check the accumulation rules: some duty allowances exclude other bonuses, which can make a change in the allowance regime less advantageous than it appears.
- Request from your HR service the details of the applicable allowance regime, including local deliberations for territorial agents.
- Ensure that the amount paid evolves with each change in step, as the ISS is indexed to the indexed salary.
The special duty allowance remains a stable element of the remuneration of hospital agents and certain territorial agents. Its logic is simple: to financially recognize real professional constraints. The trap is to consider it in isolation, without looking at the interactions with the rest of the allowance regime or the potential exclusions of accumulation that change the final calculation.
