Learn › Income tax in Czechia

In short: Czechia taxes personal income at two rates as of 2026: 15% on the part of the tax base up to CZK 1,762,812 per year (which equals 36 times the average wage), and 23% on the part above that. Most people then subtract the basic taxpayer credit (sleva na poplatníka) of about CZK 30,840 per year, which lowers the tax due directly. The tax is administered by the Finanční správa. These figures are indexed and can change, so check the official source when in doubt.

Income tax basics in Czechia

Kontoo editorial team · Updated 06/24/2026

If you earn money in Czechia, part of it goes to personal income tax (daň z příjmů fyzických osob). The system rests on two rates and one widely used credit, so once you grasp those pieces the rest follows. This lesson walks through how the tax is calculated, who collects it, and what the headline numbers are as of 2026. It is educational background, not tax advice — when a specific figure or your own situation matters, confirm it with the official source.

Start with your taxable base (broadly, income from employment or business, minus what the rules let you exclude). For most employees the employer reports this to the tax office.
Apply the rate. As of 2026, the part of the base up to 36 times the average wage — CZK 1,762,812 per year — is taxed at 15%; anything above that is taxed at 23%.
Subtract tax credits. The basic taxpayer credit (sleva na poplatníka) is about CZK 30,840 per year as of 2026 and is deducted from the tax itself, not from your income.
Settle up. Employers withhold tax monthly; the year is reconciled through an annual settlement or a tax return filed with the Finanční správa (the Czech Financial Administration).

What matters

Personal income tax in Czechia is more approachable than it first looks because it is built from just a few moving parts. The base is your taxable income. On top of it sit two rates: a 15% rate that covers most earners, and a 23% rate that applies only to the portion of income above a high threshold. As of 2026 that threshold is CZK 1,762,812 per year, defined as 36 times the average wage, so it shifts slightly each year as wages rise. The second key piece is the basic taxpayer credit, the sleva na poplatníka, worth roughly CZK 30,840 per year as of 2026. The word credit matters: it is taken off the tax you owe, not off your income. A credit of CZK 30,840 at the 15% rate corresponds to about CZK 205,600 of income carrying no net tax, which is why many lower earners owe little or nothing. Collection is handled by the Finanční správa. Employees normally have tax withheld monthly by their employer and the year is squared up through an annual settlement; the self-employed file their own return. Because the threshold and credit are indexed and revised by law, treat the numbers here as a 2026 snapshot and verify current values on the official portal before relying on them.

ExampleSuppose your annual tax base is CZK 600,000 in 2026. The whole amount sits below the CZK 1,762,812 threshold, so it is all taxed at 15%: 600,000 × 15% = CZK 90,000. Now subtract the basic taxpayer credit of about CZK 30,840: 90,000 − 30,840 ≈ CZK 59,160 of income tax for the year, or roughly CZK 4,930 per month. (Rounded, illustrative, and before any other credits such as for children or a spouse. Social and health insurance are separate from income tax. As of 2026 — check the official source when in doubt.)

In depth

Why the threshold moves each year

The line between the 15% and 23% rates is set as 36 times the average wage rather than a fixed crown amount. Because the average wage is recalculated annually, the threshold drifts upward over time — CZK 1,762,812 for 2026. That indexing keeps the higher rate aimed at genuinely high earners rather than quietly pulling in more people through inflation. Always read the figure as a year-specific number.

Credits versus deductions

Czech tax law distinguishes deductible items, which lower your taxable base before the rate is applied, from credits (slevy), which lower the tax after it is calculated. The basic taxpayer credit is a credit, so its full value reduces the bill crown-for-crown. Other credits exist for spouses with low income and for children. Understanding which lever you are pulling — base or tax — makes the whole calculation easier to reason about.

How most employees experience it

Many employees never file a separate return: the employer withholds income tax monthly and runs an annual settlement (roční zúčtování) on request, applying the credits. The self-employed and those with other income generally file an annual return with the Finanční správa. Either way the underlying math is the same — base, two rates, credits — only the paperwork path differs.

Checklist

The 15% rate applies up to CZK 1,762,812 of tax base per year (2026); 23% applies only to the part above that.
The 23% rate hits only the income above the threshold, not your entire income.
The basic taxpayer credit (sleva na poplatníka) is about CZK 30,840 per year and is subtracted from the tax, not the income.
Income tax is administered by the Finanční správa, with monthly withholding for employees and annual returns for the self-employed.

Common myths

Myth: Once I earn over the threshold, all my income is taxed at 23%.

Reality: Only the slice above CZK 1,762,812 (2026) is taxed at 23%. The rest stays at 15%, so a raise that crosses the line never leaves you with less take-home pay overall.

Myth: The sleva na poplatníka reduces how much income is taxed.

Reality: It reduces the tax itself, not the income. As of 2026 it is worth about CZK 30,840 a year, deducted straight from the calculated tax — which is why it can wipe out the tax on modest earnings entirely.

Frequently asked questions

Does the 23% rate apply to my whole income once I cross the threshold?

No. Only the part of your tax base above CZK 1,762,812 (as of 2026) is taxed at 23%; everything up to that line is still taxed at 15%. This is how a progressive bracket works — crossing the threshold never makes your entire income more expensive.

What is the sleva na poplatníka?

It is the basic taxpayer credit that nearly every taxpayer can claim. As of 2026 it is about CZK 30,840 per year and is subtracted from the calculated tax, not from your income. Because it reduces tax directly, it makes a meaningful slice of low income effectively tax-free.

Who do I deal with for income tax in Czechia?

The Finanční správa (Financial Administration of the Czech Republic) collects income tax and processes returns. Employees usually have tax withheld by their employer each month, with a yearly reconciliation; the self-employed typically file an annual return themselves.
