How this Czech Republic income tax calculator works
This calculator is designed to give a fast estimate of annual and monthly net income for employees in the Czech Republic. You enter your annual gross salary, optional bonus income, eligible deductions, and the number of dependent children. The tool then estimates income tax and employee insurance contributions.
1) Income tax bands
The calculation uses two income tax rates:
- 15% on annual tax base up to the first threshold.
- 23% on annual tax base above that threshold.
The threshold in this calculator is set to 1,582,812 CZK. If policy values are updated in future years, results should be treated as a close estimate rather than an official filing amount.
2) Employee social and health insurance
For a standard employment scenario, the calculator applies:
- Social insurance: 6.5% of gross employment income
- Health insurance: 4.5% of gross employment income
These are deducted from your gross income to estimate take-home pay.
3) Tax credits
The calculator supports common annual credits:
- Basic taxpayer credit: 30,840 CZK (optional checkbox)
- Child credit: 15,204 CZK for first child, 22,320 CZK for second, and 27,840 CZK for third and each additional child
Credits reduce your calculated income tax. In this simplified model, negative tax payouts (cash child bonus) are not modeled.
Step-by-step: using the calculator
- Enter your annual gross salary in CZK.
- Add annual bonus or other taxable employment income if you have any.
- Enter non-taxable deductions that reduce your tax base.
- Add the number of dependent children.
- Keep or remove the basic taxpayer credit option.
- Click Calculate net income to view annual and monthly estimates.

- All statutory deduction categories and eligibility rules
- Special situations for non-residents
- Self-employed (OSVČ) tax and insurance formulas
- Year-specific legislative updates after publication
- Complex child tax bonus constraints and minimum-income tests
