How Personal Income Tax Works in Czechia (2026): Rates, Credits and Allowances
In 2026, Czech personal income tax is charged at 15% on a tax base up to CZK 1,762,812 per year (36 times the average wage) and at 23% on the excess. Employees who sign a tax declaration receive a basic personal credit of CZK 2,570 per month; child tax credits can generate a cash refund called the danovy bonus. This is informational only — always verify with a qualified tax professional.
Two tax rates and the progressive threshold
The Czech Income Tax Act (ZDP — Zakon o daních z príjmu) sets two rates for individuals: 15% and 23%. The threshold between them is linked to the average wage (prumerna mzda) published annually. For 2026 the annual threshold is CZK 1,762,812 — exactly 36 times the average wage — and the monthly threshold used for advance withholding (zalova na dan) is CZK 146,901, which is three times the average wage. Income up to these thresholds is taxed at 15%; any excess is taxed at 23%. Because the monthly threshold is set at a level that only the highest salaries reach, the vast majority of Czech employees pay only the 15% rate in practice.
Tax base and statutory rounding
For the employee monthly advance tax, the tax base is the gross salary rounded up to the nearest CZK 100 — a rule prescribed by law (CEIL_100). The base used for calculation can therefore be up to CZK 99 higher than the actual gross wage. The calculated advance is then rounded down to the nearest crown. For self-employed persons (OSVC), the annual tax base is profit rounded down to the nearest CZK 100. Czech payroll abolished the superseded gross-up system (superhruba mzda) from 2021, so employer social and health insurance contributions are no longer added to the employee tax base.
Tax credits: personal, spouse and disability
The most widely used credit is the basic personal credit (sleva na poplatnika) of CZK 30,840 per year — CZK 2,570 per month. It is available to every employee who signs the tax declaration (prohlaseni poplatnika) with their employer under section 38k ZDP. The credit is subtracted directly from the calculated tax; if the credit exceeds tax due it reduces tax to zero but is not refunded as cash. The spouse credit (sleva na manzel/manzelku) of CZK 24,840 per year was tightened from 2024: it now requires the spouse to live in a shared household with a child under three years of age and to have had income not exceeding CZK 68,000 in the tax year (Act 349/2023 Sb.). Disability credits are CZK 2,520 per year for first or second degree disability and CZK 5,040 per year for third degree. Holders of a ZTP/P card receive CZK 16,140 per year. The student credit and the childcare placement credit were both abolished from 1 January 2024.
Child tax credits and the danovy bonus
Child tax credits (danove zvyhodneni) in Czechia can generate a positive cash payment to the employee when they exceed the income tax advance due. The annual credits are CZK 15,204 for the first dependent child (CZK 1,267 per month), CZK 22,320 for the second child (CZK 1,860 per month), and CZK 27,840 for the third and each further child (CZK 2,320 per month). When the total monthly child credits exceed the advance tax due, the employer pays the surplus to the employee as the danovy bonus. The monthly bonus requires: gross salary of at least CZK 11,200 (half the 2026 minimum wage) and a bonus of at least CZK 50. At annual level, the minimum qualifying income is CZK 134,400.
Annual settlement and tax return obligations
Employees with a signed tax declaration at a single employer and no other significant income can ask the employer to carry out an annual tax settlement (rocni zuctovani zalohy) — they do not need to file a personal tax return. A tax return (danove priznani) is compulsory for taxpayers with self-employment or rental income above the statutory threshold, with income from multiple employers, or with foreign income. The deadline for paper returns is 1 April; the deadline for electronic filing or filing via a certified tax adviser is 1 July. These are general rules — your specific obligations should always be confirmed with a qualified adviser.
FAQ
When does the 23% income tax rate apply?
The 23% rate applies to the portion of the monthly tax base (zaklad dane) exceeding CZK 146,901 when computing monthly advance withholding, or to the portion of the annual tax base above CZK 1,762,812 in the annual settlement or tax return. Both thresholds are derived from the 2026 average wage. For most Czech employees the 23% rate is never reached.
What is the prohlaseni poplatnika and why does it matter?
The prohlaseni poplatnika (taxpayer declaration, section 38k ZDP) is a signed form submitted to the employer that authorises the employer to apply monthly tax credits against advance withholding — primarily the basic personal credit of CZK 2,570 per month and child tax credits. Without it, no credits are applied and monthly withholding is higher. The form is typically signed at the start of each year or when starting a new job, and an employee can only hold one active declaration at a time.
Can an employee receive more in child credits than they owe in income tax?
Yes — that is exactly when the danovy bonus arises. When monthly child credits exceed the advance income tax due, the employer pays the difference to the employee as a cash bonus on top of net salary. The gross salary in that month must be at least CZK 11,200 and the bonus must be at least CZK 50.
Does Czechia tax foreign income for Czech tax residents?
Czech tax residents — those with a permanent home or habitual abode in Czechia — are taxed on worldwide income. Foreign-source income is included in the annual Czech tax return; double taxation is typically relieved through tax treaties using the exemption or credit method. Non-residents are taxed only on Czech-source income. The rules can be complex when multiple jurisdictions are involved — professional advice is strongly recommended.
