How Čistá mzda (net salary) in Czechia is calculated
Czech payroll deducts 7.1% social insurance and 4.5% health insurance from gross, then charges 15% income tax on the gross (23% above a high threshold).
Two credits then cut the tax: a flat monthly taxpayer credit and a per-child tax advantage that can even turn into a paid-out bonus when it exceeds the tax due. The calculator applies both. Estimate, not tax advice.
