A territorial administrative assistant at the 5th level and a hospital technical assistant at the same level do not have the same increased index, but in 2026, they often receive the same gross monthly salary. The freeze on the index point, combined with successive increases in the minimum wage (SMIC), has created a situation where the salary scale no longer reflects the reality of the payslip for a large number of category C agents.
Differential allowance and SMIC 2026: the trap of comparison based solely on the scale
We start with the point that skews all comparisons made hastily. The SMIC was increased twice in 2026: +1.18% on January 1 and +2.41% on June 1. The index point, on the other hand, remains frozen for the third consecutive year.

Concrete result: according to a document from CDG 53 updated on June 1, 2026, the first 10 levels of grade C1, the first 7 of grade C2, and the first 3 of grade C3 generate a salary index lower than the SMIC. For these agents, the administration pays a differential allowance that brings the salary up to the minimum wage level.
A statement from the Ministry of Economy on May 28, 2026, quantifies the phenomenon: 862,000 public agents benefit from this differential allowance as of June 1, 2026. We are talking about a massive mechanism, not a marginal case.

The direct consequence for those who want to compare category C salaries in 2026: several successive levels result in the same gross monthly amount. Comparing two payslips based solely on the increased index gives a misleading picture. The differential allowance must be included in the calculation; otherwise, we are comparing theoretical figures that do not correspond to any actual bank transfer.
Gross salary category C: the formula and its limits in 2026
The gross monthly salary of a civil servant is calculated by multiplying the increased index by the value of the index point. Since July 2023, this value is set at 4.92 euros. This gives a gross amount to which, if applicable, the residence allowance and the family supplement are added.
For a C1 agent at the 1st level (increased index 366), the theoretical gross monthly salary is therefore 366 x 4.92 euros. This amount falls below the gross monthly SMIC applicable on June 1, 2026, triggering the automatic payment of the differential allowance.
What the salary scale shows and what it hides
The scale remains useful for a specific purpose: to visualize long-term career progression. It shows how many levels separate a C1 from a principal C2, and how many years it takes to reach the top of the grade. On this point, the scales published by management centers remain the reference.
However, the scale says nothing about three elements that weigh heavily in actual remuneration:
- The allowance system (bonuses and allowances), which varies greatly from one community to another and from one branch of the public service to another. A technical assistant in a rural community and their counterpart in a university hospital do not receive the same bonuses, even at the same grade and level.
- The differential allowance, paid only when the salary index falls below the SMIC, which concerns in 2026 the majority of the first levels of category C.
- Overtime, on-call duties, and specific bonuses (night work, weekends), particularly common in the hospital public service.
Comparing the three branches of the public service in category C
Comparing category C salaries between the state public service (FPE), the territorial public service (FPT), and the hospital public service (FPH) requires going beyond the common salary scale. The indices are identical from one branch to another for the same grade and level. It is on the allowance system that everything is at stake.
Territorial public service: disparities between communities
In the FPT, each community sets its own decisions regarding bonuses. An administrative assistant in a metropolis may receive a significantly higher allowance system than an agent at the same grade in a small municipality. The salary index is national, the allowance system is local.
Hospital public service: bonuses related to constraints
In the FPH, category C agents benefit from specific bonuses related to the constraints of the job (night work, Sundays, public holidays). These constraints can represent a significant portion of total remuneration, making comparisons with an administrative position in a town hall less relevant if limited to the basic salary.
State public service: RIFSEEP as a variable
In the FPE, the allowance system that takes into account functions, constraints, expertise, and professional commitment (RIFSEEP) applies to most category C bodies. The amounts vary depending on the ministry of assignment and the group of functions assigned to the position.
Concrete method for comparing two category C payslips
Rather than sticking to the scale, it is recommended to reason based on the total net monthly remuneration, including bonuses. Here are the elements to align for the comparison to make sense:
- Check the gross salary index (increased index x 4.92 euros) and ensure it exceeds the current gross SMIC. If not, replace it with the SMIC amount.
- Add the allowance system specific to the position, distinguishing between the fixed part (IFSE under the RIFSEEP) and the variable part (CIA or equivalent).
- Include the residence allowance (from 0% to 3% of the gross salary depending on the geographical area) and the family supplement if applicable.
- Compare the net amounts after social contributions, which differ slightly between FPT, FPH, and FPE.
Feedback varies on the ease of obtaining this information before starting a position. Job descriptions published on public employment sites rarely mention the details of the allowance system. Asking for the average amount of bonuses during the recruitment interview remains the most reliable way to obtain usable figures.
The compression of category C scales towards the SMIC in 2026 makes index-based comparisons less and less relevant for the first levels. The real difference in remuneration between two category C positions now almost entirely hinges on bonuses, constraints, and the geographical location of the position.
