What is PTU (reparto de utilidades)?
The PTU (Participación de los Trabajadores en las Utilidades) is the right to receive a share of the company's profits. It is distributed according to days worked and salary earned.
The individual amount has a cap: the lower of three months of salary or the average PTU of the last three years. It is paid in May (legal entities) or June (individuals).
In practice
A profitable company distributes the PTU among its staff; each worker receives a share according to the days they worked and their salary, with the legal cap of three months.
