# Czechia: individual tax residence A substantive Czech home or at least 183 days of presence can establish domestic tax residence. Treaty rules and special-purpose stays can change the outcome and the reach of worldwide taxation. Scope: Baseline individual income-tax residence and worldwide versus source taxation, using the tax authority's 2026 residence memorandum; not a rate or filing calculation. Jurisdiction: Czech Republic. Sources reviewed 2026-09-17; review due 2026-12-16. General information, not personal tax advice. Nationality, tax residence and source of income are different questions. Consult the tax authority or a qualified adviser for your circumstances. ## Substantive home is an independent test A home available to the individual, together with circumstances showing an intention to reside there permanently, can establish domestic residence. Family, personal and economic facts matter. Immigration registration alone does not decide it; the home and presence tests are alternatives, not sequential tests. Evidence: conditional.

Source location: 2026 memorandum section 1.1, domicile discussion, pages 1–3. ## Presence and study or treatment exception Habitual presence is at least 183 days in the calendar year, adding separate visits and counting any part of a day. Individuals staying solely for study or medical treatment fall within the special nonresident rule, even if a domestic home or presence criterion is met. Evidence: conditional.

Nonresidents have Czech-source-only scope under the income-tax law, and an applicable treaty may restrict Czech taxation of that source income. Evidence: conditional.

Source location: Memorandum section 1 introduction; cross-border guide: resident and nonresident obligations. ## Treaties and foreign tax Domestic residence in both countries requires the actual treaty's ordered tie-breakers. Czech residents' foreign tax is handled under the applicable treaty and section 38f; it is not automatically refunded or universally exempted. Without a treaty, the guide points only to narrower domestic mitigation provisions. Evidence: conditional.

Source location: Memorandum section 1.2; cross-border guide: obligations of a tax resident, references to sections 38f, 6(13) and 24(2). ## Residence changes within a year Meeting the domestic habitual-presence test is assessed for the whole calendar year. A change in home or treaty circumstances can instead produce different residence periods within a year, with worldwide scope while resident and source-only scope while nonresident.

The broader business guide is used only for income scope and foreign-tax relief, not its simplified domestic residence discussion. - Income-specific treaty articles, pensions, withholding, social contributions and rates require separate treatment. ## Explore this passport - [Passport rank and travel access](https://multipassrank.com/passport/czechia) - [Citizenship requirements](https://multipassrank.com/passport/czechia/citizenship) - [Country-profile JSON, including sources and scoped requirements](https://multipassrank.com/api/v1/country-profiles/CZ) - [Multiple-citizenship policy guide](https://multipassrank.com/dual-citizenship-countries) [Canonical page](https://multipassrank.com/passport/czechia/taxes)
