Tax Residence (daňový domicil) in Czechia: Who Counts as a Tax Resident

What daňový domicil is — and why it matters

Tax domicile (daňové rezidentství) answers one question: which country treats you as its taxpayer with unlimited tax liability (poplatník s neomezenou daňovou povinností). For individuals this is decided by § 2 of the income-tax act. It matters because it fixes the scope of taxation — a resident is taxed in Czechia even on foreign income, a non-resident only on what they earn here.

• Czech tax resident → taxed in Czechia on worldwide income (celosvětové příjmy — Czech and foreign).
• Czech tax non-resident → taxed here only on Czech-source income (příjmy ze zdrojů na území ČR).
• Status is assessed per tax period (the calendar year) and can change from year to year as your life changes.

So tax domicile is critical for anyone with income from more than one country — freelancers (OSVČ) with foreign clients, employees working across borders, investors and landlords. Without a clear domicile the same money risks being taxed by two states at once.

Who is a Czech tax resident: bydliště and the 183-day rule

Under § 2 of Act No. 586/1992 Sb. you are a Czech tax resident if you meet at least one of two conditions. Either one is enough on its own.

• Bydliště in Czechia — a permanent dwelling (owned or rented) available to you at any time, kept under circumstances showing an intention to settle here permanently. It does NOT have to be the same address as your immigration trvalý pobyt.
• Presence of at least 183 days in a calendar year — continuously or across several periods. Every day of presence counts, including the day of arrival and the day of departure, plus weekends and holidays.

The bydliště test is about your real centre of life interests — where your home, family and main personal and economic ties are concentrated. That is also what usually decides things when two countries both claim you as their resident. People who are present fewer than 183 days and have no bydliště here (for example short-term students) are non-residents and tax only their Czech-source income.

Tax residence is not a residence permit — two different statuses

This is the most frequent confusion. A residence permit and tax residence are not directly linked and are governed by different laws.

• Permanent / long-term residence (trvalý / dlouhodobý pobyt, ПМЖ): an immigration status under Act No. 326/1999 Sb. — as a rule 5 years of prior legal stay plus passing the A2 Czech exam — giving the right to live and work here.
• Tax residence (daňové rezidentství): a tax status under Act No. 586/1992 Sb. — bydliště OR 183+ days — creating the duty to tax worldwide income.
• Permit test: years of legal residence, purpose, exams. Tax test: bydliště or 183 days.

In practice the two usually overlap — you live here, hold a Czech permit and are a Czech tax resident at the same time. But you can hold one without the other: for example, permanent residence in Czechia while working abroad more than 183 days a year, which can make you a tax resident of that other country. The residence card alone does not decide your taxes.

Certificate of tax domicile: where, how, documents and the 100 Kč fee

The certificate of tax domicile (potvrzení o daňovém domicilu) is your official proof that you are a Czech tax resident. You typically need it when your home country or a foreign employer wants a document so they don't tax the same income twice, when a foreign client withholds tax, or for banks and investment platforms under FATCA/CRS. It is issued by the locally competent tax office (místně příslušný finanční úřad) for your bydliště.

1. File an application (žádost) with your finanční úřad — in free form or on the recommended GFŘ template, form MFin 25 5232 (vzor 5232). There is no legally prescribed form.
2. State your name, date of birth, rodné číslo or DIČ, your Czech bydliště address and any foreign address, the tax period requested, the purpose/country where it will be used, and why you are a Czech resident (bydliště, or meeting the 183-day test).
3. Submit it in person, by post, via datová schránka, or through the MOJE daně portal.
4. Pay the administrative fee of 100 Kč (správní poplatek under Act No. 634/2004 Sb.) and collect the certificate.

Double-tax treaties and avoiding being taxed twice

When two countries both want to treat you as their resident, double-tax treaties (smlouvy o zamezení dvojího zdanění, DTTs) step in. Czechia has treaties with most countries; the up-to-date list and the treaty texts are published on the Ministry of Finance (MF ČR) website. A treaty contains tie-breaker rules that override the domestic test and decide whose resident you are.

1. Permanent home — in which country a home is permanently available to you.
2. Centre of vital interests — where your personal and economic ties are concentrated.
3. Habitual abode — where you actually spend more time.
4. Nationality, and as a last resort agreement between the two tax administrations.

The treaty also sets the method for removing double taxation — either exempting the income or crediting the tax already paid abroad. So always check whether Czechia has a treaty with your home country, and what it says for your specific type of income, before you assume where it is taxed.

Filing via MOJE daně: deadlines and the tax credits tied to domicil

Tax returns are filed through the MOJE daně portal (adisspr.mfcr.cz), with login via Identita občana (BankID, MojeID, eObčanka) or a datová schránka. Anyone with a statutorily established data box must file electronically.

• Basic deadline: 3 months after the tax period — 1 April.
• Electronic filing via MOJE daně: extends the deadline by one month, to 1 May (4 months).
• Filing by a tax advisor under a power of attorney, or where your accounts are audited: 6 months — 1 July.

Several tax credits (slevy) for 2026 depend on having Czech tax domicile. For the spouse and child credit, a foreign resident needs a Czech daňový domicil (centre of life interests here, or 183+ days a year); a non-resident can claim them only if at least 90% of worldwide income is Czech-source.

• Basic taxpayer credit (sleva na poplatníka): 30 840 Kč/year — automatic for everyone.
• Spouse credit (sleva na manžela/manželku): 24 840 Kč/year (49 680 Kč if the spouse holds ZTP/P). Conditions: shared household, spouse's own income under 68 000 Kč/year, and — since 2024 — caring for a child under 3 in the household.
• Child credit (daňové zvýhodnění na dítě): 15 204 Kč first child, 22 320 Kč second, 27 840 Kč third and further (doubled for a ZTP/P child).
• Student credit (sleva na studenta): remains abolished in 2026. A government proposal would reinstate it (with školkovné) for tax period 2027 — not yet enacted, so treat it as planned only.
