Form 100. Personal Income Tax Return 2025

10.1.1. By birth, adoption of children or foster care of minors

Amount

Requirements and conditions

  • When two taxpayers are entitled to apply the deduction, the amount will be distributed equally. 

  • In the case of foster care, only the taxpayer who has not received aid from the Administration of the Autonomous Community of Andalusia related to the foster care may apply the deduction. In addition, the minor must live with the taxpayer for at least 90 days during the tax period in which the foster care takes place.

    This deduction will not be given for pre-adoption foster care when the adoption of the minor has taken place during the tax period, without prejudice to the application, where appropriate, of the deduction for adoption.

Incompatibility

This deduction is incompatible with respect to the same children, with the application of the regional deduction "For adoption of children in the international sphere" and, in any case, with the application of the regional deduction "For large families".

Completion

You must indicate in box " Common" or in the box "Of the holder", as indicated below, the number of children or the number of minors in foster care, taking into account that the same child or minor in foster care can only be entered in one of the two boxes.

 The "Common" box must be completed in the case of marriage when the children are common to both spouses or the minors are taken in by both spouses and both have the right to apply the deduction.

Otherwise, or when in the case of marriage the option has been chosen for individual data capture, the number of children or fostered minors will be reflected in the "Of the holder" box. In this case, you must also fill in the number of people who have the right to apply the deduction with respect to those children or foster children, indicating a 1 if the right to the deduction corresponds only to the taxpayer or a 2 if there are two people entitled to it.

Additionally, you must indicate, if applicable, the number of children born, adopted, or fostered during the year resulting from multiple births, adoptions, or foster care.

If the taxpayer resides in a municipality with depopulation problems, he/she will check the box provided for that purpose.
