In this article the regulations of the act on parental supplementary benefit of January 30, 2019 are thoroughly analysed. Supplementary parental benefit is granted to a person who gave birth to and raised or only raised at least four children and did not acquire the right to a pension or a pension paid to this person by the pension authority is smaller than the lowest pension. One is entitled to the benefit mentioned herein only in the case of not having means of subsistence because of not pursuing or discontinuing employment as a result of raising minimum four children. Supplementary parental benefit is in no way related to making social security contributions, it is a benefit financed by the state budget, which in a supplementary or substitutional way is linked to old age. In the legal sense, it is not a pension, but a special non-contributory monetary benefit of discretionary nature, which is granted only on request of the person of interest based on the administrative decision of the president of the Polish Social Insurance Institution (ZUS) or the Agricultural Social Insurance Fund (KRUS).
