How Czechia decides tax residence
Each test is recorded separately with its own ID. Meeting or missing one test does not settle residence on its own.
Domicile (bydliště) in Czechia
Under § 2(4) of the Income Taxes Act (No. 586/1992), domicile is a permanent dwelling held in circumstances showing an intent to stay there permanently, judged by personal and family circumstances or economic activity. The dwelling can be owned or rented and must be available whenever the person needs it; in some cases a hotel or short-term rental can count. Residence under this test starts and ends on a specific day, so a person can be resident for only part of a calendar year.
Habitual stay of at least 183 days in a calendar year
A person habitually stays in Czechia if they are present there for at least 183 days in the calendar year, and every commenced day counts. Meeting this test makes the person resident for the whole calendar year, from 1 January. The date of a residence permit and the country of health or social insurance do not decide the count; presence can be shown with bank statements, personal records and travel or accommodation documents.
Stays only for study or medical treatment
Under § 2(3) of the Income Taxes Act, people who stay in Czechia only to study or receive medical treatment are not treated as resident, even if they have a domicile or habitually stay there. Guidance notes that this changes if the person starts a business or employment in Czechia, because the stay is then no longer only for study or treatment.
Arriving, leaving and part years
Under CZ-RES-01, residence starts and ends on the day domicile arises or ends, so a person can be resident for part of the calendar year and taxed on worldwide income only for that part. Under CZ-RES-02, residence covers the whole calendar year. Where a tax treaty applies, it can also split residence within a year.
Social security
Czechia applies the EU rules on social security coordination: a person is generally covered by one country's system at a time, and a PD A1 form can show continued home-country cover during a temporary posting. Check national contribution rules with the Czech social security authorities.
Living base
EU citizens can stay in Czechia for up to three months without registering and may need to register for longer stays; after five years of continuous lawful residence they acquire the right of permanent residence. Non-EU nationals generally need a long-stay visa or residence permit, handled by the Ministry of the Interior. Guidance states that the date a residence permit was granted does not decide the 183-day count; the tests above decide tax residence.
How visas, permits and tax residence differ
Citizenship
Czech citizenship is acquired mainly by descent or by naturalization after a period of lawful residence, with other routes set by national law. This record has not verified the current residence period or the position on dual citizenship; check the Ministry of the Interior's current guidance.
