# Čistá mzda kalkulačka — Czechia net salary

Source page: https://valem.run/calculators/czechia/net-salary

Your Czech net salary is gross minus 7.1% social and 4.5% health contributions and 15% income tax, after the taxpayer and child credits.

**Tax year:** 2026

## How it 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.

## Worked example

With Hrubá mzda / měsíc of 45,000 CZK, this model computes Čistá / měsíc of 35,600 CZK.
