Czech Republic Tax Residency Guide

Tax Residence Criteria

Under Section 2 of the Czech Income Tax Act (zákon o daních z příjmů), an individual is a Czech tax resident if they have a bydliště (habitual abode) in the Czech Republic or physically present in the Czech Republic for more than 183 days in a calendar year. Tax residents are subject to Czech income tax on their worldwide income. Non-residents are only taxed on Czech-source income.

183-Day Presence Rule

An individual is considered a Czech tax resident if physically present in the territory of the Czech Republic for more than 183 days in a calendar year. The days are counted cumulatively — any part of a day (including the day of arrival and the day of departure) counts as a full day. The count includes weekends, holidays, and short absences. If an individual stays in the Czech Republic for 183 days or fewer, they are not automatically considered a resident under this test (subject to the habitual abode test below).

Note that under most double tax agreements (DTAs), the 183-day count may be assessed over a 365-day period rather than a calendar year, depending on the specific treaty wording. The Czech domestic law uses the calendar year for the initial determination.

Habitual Abode — Bydliště

The habitual abode (bydliště) test is independent of physical presence. An individual has a habitual abode in the Czech Republic if they have a permanent home in the territory with the intention to reside there permanently. The key factors include: owning or renting a dwelling (apartment, house, or long-term accommodation), having family members residing in the Czech Republic, having personal belongings and furniture in the dwelling, and registering for permanent or long-term residency. A person can have only one habitual abode at a time for tax purposes, even if they own multiple properties.

Center of Vital Interests (DTA Tie-Breaker)

When an individual is considered a resident of both the Czech Republic and a treaty partner under domestic laws, the DTA provides a tie-breaker test to determine a single residence. The steps are: (1) permanent home available — if available in both states, proceed to step 2; (2) center of vital interests — the state with which the personal and economic relations are closer (closer personal and economic relations); (3) habitual abode — if the center of vital interests cannot be determined, the state where the individual more habitually stays; (4) nationality — if still unresolved, the state of nationality; (5) mutual agreement — if all else fails, the competent authorities of both states resolve the matter by mutual agreement.

Notification Obligation

A change of tax residence (moving to or from the Czech Republic) must be notified to the relevant tax administrator (Finanční úřad). The notification is typically made as part of the annual tax return (daňové přiznání) or by filing a specific notification form (oznámení o změně bydliště pro daňové účely). Failure to notify can result in penalties, including fines for non-compliance. Individuals leaving the Czech Republic should also inform their health insurance company (zdravotní pojišťovna) and the Czech Social Security Administration (ČSSZ) if applicable.

FAQs

Can I be a tax resident of two countries at the same time?

Under domestic laws, yes — you can meet the residence criteria in both countries simultaneously. However, the applicable double tax agreement (DTA) will contain tie-breaker rules to determine a single country of residence for treaty purposes. If no DTA exists, or the tie-breaker does not resolve the matter, you may face double taxation on your worldwide income.

Does the 183-day rule apply to EU citizens?

Yes, the 183-day rule applies regardless of nationality. EU/EEA citizens are subject to the same residence rules as any other nationality. However, posted workers from other EU member states may remain subject to their home country's social security under A1 forms, but this does not affect income tax residence.

What is the difference between permanent residence (trvalý pobyt) and tax residence?

Permanent residence (trvalý pobyt) is a registration status under the Act on Residence of Foreign Nationals and does not automatically determine tax residence. A person with trvalý pobyt in the Czech Republic may still be a non-resident for tax purposes if they do not meet the 183-day or habitual abode test, and vice versa.
