"“Our tax system is very family-friendly,” Novák explained. “The more children you have, the less personal income tax you pay. From January 1, 2020, mothers with at least four children have a full exemption from personal income tax. They don’t pay personal income taxes ever in their lives.” Additionally, from January 1, 2022, young people under 25 will receive a full exemption from income tax. Everyone else pays a flat tax of 15 percent, which is reduced based on the number of children you have.
