Self-employed persons (OSVČ) are obliged to pay advances for social and health insurance. During the first year of business, only the minimum amount of advances is paid. In the following years of business, the amount of the monthly advance is based on the profit achieved last year and is calculated in the Statements of Income and Expenditures (Přehledů o příjmech a výdajích) that all self-employed persons must deliver annually to their health insurance company and the relevant Czech Social Security Administration.
