Family Treatment Supplement (FTS) in the Public Service

Verified 08 February 2024 - Directorate for Legal and Administrative Information (Prime Minister)

Are you a civil servant or a contract worker and you have at least 1 dependent child? You are entitled to a supplement called family treatment supplement (FTS). The conditions of award vary depending on whether you and the other parent are all 2 public officials or only one of you is a public official. They also vary depending on whether you live as a couple or are separated. We present the conditions for the award of this additional remuneration.

2 parents public officials

The Family Salary Supplement (FTS) is a supplement to remuneration paid to any public official (civil servant or contract employee) who has at least 1 child under 20 (within the meaning of family benefits).

If you and the other parent are all 2 public officials, the SFT is paid to only one of you on the basis of a joint declaration of choice by the beneficiary.

This choice may be amended at the end of a period of one year.

As the amount of the SFT depends primarily on the premium index, the higher the premium index of the chosen parent, the higher the amount of the SFT.

You must request the FTS in writing from your Human Resources Branch.

It will indicate the supporting documents to be submitted (copy of the family record, birth certificate, etc.).

The SFT shall be paid every month, from 1er day of calendar month following the period during which the conditions for entitlement to such benefits are fulfilled.

Example :

The SFT shall be paid from 1er November in case of birth on October 13.

Payment shall cease from 1er the day of the month in which the conditions are no longer met.

Example :

The payment of the SFT shall cease from 1er June for a child reaching the age of 20 on June 27.

The amount of the SFT depends on the number of children you have and your gross index processing.

The amount of the SFT includes a fixed element that depends on the number of children in your care and an element proportional to your gross index treatment.

If you get a new index enhancement (NBI), it is in addition to your index salary for the calculation of the SFT.

Example :

If you are remunerated on the basis of the index plus 485 and receive an NBI of 10 points, your SFT is calculated on the basis of the index plus 495.

The sum of the 2 components of the SFT may not be less than a minimum amount or more than a maximum amount.

The minimum amount of the SFT is the SFT corresponding to index plus 454 and the maximum amount is the SFT corresponding to index plus 722.

Thus, if your index plus is less than 454, you receive the SFT at the minimum rate corresponding to the index plus 454.

And if your index plus is greater than 722, you receive the SFT at the maximum rate corresponding to the index plus 722.

If your index increase is between 454 and 722, you benefit from a SFT partly proportional to your gross salary.

Example :

If you are paid on the 461 plus index and have 4 dependent children, you receive a SFT equal to the following amount:

€15.24 + €4.57 + [(461x €5,907.34 / 1200) x 8%] + [(461 x €5,907.34 / 1200) x 6%] = €15.24 + €4.57 + 181.55 + 136.16 = €337.53

If you work part-time, your SFT is reduced under the same conditions as your index treatment unless you have only one child.

In this case, the fixed element of €2.29 is not reduced.

However, your SFT cannot be less than the minimum amount paid to a full-time employee with the same number of dependent children.

Example :

If you are remunerated on the basis of the 461 plus index, have 4 dependent children and work at 50%, your SFT should in principle be:

(€15.24 / 2 + €4.57 / 2 + [(461 x €5,907.34 / 1200 / 2) x 8%] + [(461 x €5,907.34 / 1200 / 2) x 6%] = 7.62 + 2.29 + 90.78 + 68.08 = €168.76

However, the minimum amount of the SFT (calculated on the basis of the index plus 454) for a staff member who works full-time and has four children is equal to €194.03 +€138.66, or €332.69.

So that's the minimum amount that's paid to you.

If you work at incomplete or incomplete time, the SFT is paid on the basis of the number of hours of service in relation to the legal and weekly working time, unless you have only one child.

In this case, the fixed element of €2.29 is not reduced.

Example :

If you are paid on the 461 index, have 4 dependent children and work 25 hours a week, you receive a SFT equal to the following amount:

(€15.24 x 25 / 35) + (€4.57 x 25 / 35) + [(461 x €5,907.34 / 1200 x 25 / 35 ) x 8%] + [(461 x €5,907.34 / 1200 x 25 / 35) x 6%] = 10.89 + 3.26 + 129.68 + 97.26 = €241.09

The SFT can be combined with the others family allowances to which you are entitled.

In the event of arrival or departure during the month, the amount of the SFT shall be prorated according to the number of days present, like any other remuneration element, including where it is set at €2.29.

Please note

In the event of sick leave, long-term or long-term illness and strike, the SFT shall be maintained in full.

Right of custody granted to one or other of the parents

If one of you has custody of all the children, the SFT is calculated on the basis of your increased index.

If you have custody of one or more children and your ex-spouse, the custody of one or more other children, each of you receives a FTS calculated on its index and the number of dependent children.

However, in the 2 cases, you can request that the SFT be calculated according to your ex-spouse's index, if it is higher, possibly taking into account all the children in his or her care.

You must make a written request to the management department of your former spouse.

The SFT is then paid to each of you in proportion to the number of children in your respective care.

Example :

  • A couple had two children. The mother has the two dependent children. She receives the SFT for 2 children at her increased index. But she can request that her SFT be calculated on the basis of the index plus her former spouse if it is higher.
    If his ex-spouse has a 3me As a child of a new union, she receives a SFT supplement equal to the difference between the SFT for 2 children in her index and the 2/3 of the SFT for 3 children in the index of the father.
  • A couple had two children. One of the children is dependent on the mother, the other on the father. Each parent receives half of the SFT for 2 children based on their own index.
    The mother has 1 other child from a new union, 2 dependent children: she receives 2/3 of the SFT for 3 children at her index.
    If the father applies for the SFT on the basis of his ex-spouse's index, he shall receive a SFT supplement equal to the difference between half of the SFT for 2 children on his index and 1/3 of the SFT for 3 children on the mother's index.

You are entitled to the SFT if you assume the actual and permanent burden of the children, even if your former spouse pays you maintenance.

Alternate custody

In the case of the child's alternate residence, the SFT may be shared by half between the two parents on joint request or at the request of one of them.

If you make a joint request for sharing, you can only request the modification of these conditions of payment after one year, unless the conditions of residence of the child change.

The SFT due to each parent is calculated as follows:

First, the Basic SFT according to all children under the care of the staff member (alternate custody and other dependent children).

Then, each child is given a coefficient that depends on how they are cared for:

  • If he is in alternate custody, his coefficient is 0.5
  • If the child lives permanently in the parent's home, his coefficient is 1

Then, for each child, the calculation is as follows:

Basic SFT x coefficient / number of dependent children

Finally, the SFT of each child must be added up.

Example :

A couple had two children who are in alternate care.

The mother has 1 other child (3 in total) and the father has 2 other children (4 in total).

For the mother, the basic SFT is calculated on the basis of 3 children, i.e. €231.45for an index increased by 549.

From this basic amount, its SFT is calculated as follows:

You can request that your SFT be calculated on the basis of your ex-spouse's index salary, if it is higher than yours.

In this case, your SFT is calculated as follows:

First, the Basic SFT based on all children in the care of your former spouse (alternate custody and other dependent children).

Then each child is applied for which you are responsible the coefficient which depends on its mode of custody.

Then, for each child, the calculation is as follows:

Basic SFT x coefficient / number of dependent children of your ex-spouse.

Finally, the SFT of each child must be added up.

Example :

A couple had two children who are in alternate care.

The father has another dependent child (3 in total).

The mother requests that her SFT be calculated on the basis of the father's SFT.

If the parent's basic SFT is for example €107.25the amount of the mother's SFT shall be calculated as follows:

1 parent public official

The Family Salary Supplement (FTS) is a supplement to remuneration paid to any public official (civil servant or contract employee) who has at least 1 child under 20 (within the meaning of family benefits).

FYI  

If your spouse working in a private company, whose collective agreement provides a benefit similar to the SFT, you can combine the SFT and this benefit.

You must request the FTS in writing from your Human Resources Branch.

It will indicate the supporting documents to be submitted (copy of the family record, birth certificate, etc.).

The SFT shall be paid every month, from 1er day of calendar month following the period during which the conditions for entitlement to such benefits are fulfilled.

Example :

The SFT shall be paid from 1er November in case of birth on October 13.

Payment shall cease from 1er the day of the month in which the conditions are no longer met.

Example :

The payment of the SFT shall cease from 1er June for a child reaching the age of 20 on June 27.

The amount of the SFT depends on the number of children you have and your gross index processing.

The amount of the SFT includes a fixed element that depends on the number of children in your care and an element proportional to your gross index treatment.

If you get a new index enhancement (NBI), it is in addition to your index salary for the calculation of the SFT.

Example :

If you are remunerated on the basis of the index plus 485 and receive an NBI of 10 points, your SFT is calculated on the basis of the index plus 495.

The sum of the 2 components of the SFT may not be less than a minimum amount or more than a maximum amount.

The minimum amount of the SFT is the SFT corresponding to index plus 454 and the maximum amount is the SFT corresponding to index plus 722.

Thus, if your index plus is less than 454, you receive the SFT at the minimum rate corresponding to the index plus 454.

And if your index plus is greater than 722, you receive the SFT at the maximum rate corresponding to the index plus 722.

If your index increase is between 454 and 722, you benefit from a SFT partly proportional to your gross salary.

If you work part-time, your SFT is reduced under the same conditions as your index treatment unless you have only one child.

In this case, the fixed element of €2.29 is not reduced.

However, your SFT cannot be less than the minimum amount paid to a full-time employee with the same number of dependent children.

However, the minimum amount of the SFT (calculated on the basis of the index plus 454) for a staff member who works full-time and has four children is equal to €194.03 +€138.66, or €332.69.

So that's the minimum amount that's paid to you.

If you work at incomplete or incomplete time, the SFT is paid on the basis of the number of hours of service in relation to the legal and weekly working time, unless you have only one child.

In this case, the fixed element of €2.29 is not reduced.

The SFT can be combined with the others family allowances to which you are entitled.

In the event of arrival or departure during the month, the amount of the SFT shall be prorated according to the number of days present, like any other remuneration element, including where it is set at €2.29.

Please note

In the event of sick leave, long-term or long-term illness and strike, the SFT shall be maintained in full.

Right of custody granted to one or other of the parents

The SFT is calculated by taking into account all children of which the public official is the parent or dependent, and by reference to its index.

The SFT is paid to each former member of the couple in proportion to the number of children they have to support.

If the non-public-servant parent has custody of all the children, he or she collects the FTS in full.

Example :

  • A couple had two children. The 2 children are dependent on the non-official parent. He collects the SFT for 2 children on the basis of the index plus the official parent
  • A couple has had 3 children, 2 are dependent on the non-official parent, 1 is dependent on the official parent.
    The SFT is calculated on the basis of the three children of the parent employee.
    The non-employee parent receives 2/3, the employee parent 1/3.
    The official parent has two other children of a new union. The SFT is calculated on the basis of 5 children. The non-official parent receives 2/5, the official parent 3/5.

FYI  

The amount of the SFT paid to the non-official parent shall be reduced by the amount of the social contributions due by the official (CSG: titleContent, CRDS: titleContent, additional pension).

Alternate custody

In the case of the child's alternate residence, the SFT may be shared by half between the two parents on joint request or at the request of one of them.

If you make a joint request for sharing, you can only request the modification of these conditions of payment after one year, unless the conditions of residence of the child change.

The SFT due to each parent is calculated as follows:

First, the Basic SFT according to all children under the care of the staff member (alternate custody and other dependent children).

Then, each child is given a coefficient that depends on how they are cared for:

  • If he is in alternate custody, his coefficient is 0.5
  • If the child lives permanently in the parent's home, his coefficient is 1

Then, for each child, the calculation is as follows:

Basic SFT x coefficient / number of dependent children

Finally, the SFT of each child must be added up.

Example :

A couple had two children who are in alternate care.

The father, a public official, has 2 other children (thus 4 in total).

First, the Basic SFT based on all children of which the father is responsible.

Then, for each parent, a coefficient is applied to each dependent child that depends on the custody mode.

Then, for each child, the calculation is as follows:

Basic SFT x coefficient / total number of dependent children of the father

Finally, the SFT of each child must be added up.

For example, if the parent's basic SFT is €451.94, the father's share shall be calculated as follows:
