Tax Residence
Determines in which country a person is considered tax resident and where income is generally taxed.

In brief for employers
Tax residency is one of the most important starting points for home office abroad, workation and Remote Work Compliance. It determines which country considers a person to be a tax resident and can therefore generally tax their worldwide income. This is relevant for employers because it can give rise to income tax, payroll, reporting and documentation issues.
In the DACH region and in the EU there is no single definition that is identical everywhere. Residence, habitual residence, center of life, family, apartment, length of stay and local registration often play a role. In addition, double taxation agreements can regulate which country the residence is assigned in cases of conflict.
Definition
Tax residency refers to the tax assignment of a person to a country. A person may appear to be resident in more than one country under national law. In such cases, a double tax treaty often helps to classify residency for treaty purposes based on tie-breaker criteria.
It is crucial for employers that tax residency is not the same as social security, immigration or employment law. A person can remain covered by social security in one country, become a tax resident in another country and still trigger a work permit issue in a third country.
Typical triggers in remote work
Tax residency should be checked if employees:
- work abroad for several months;
- travel repeatedly to the same country;
- use a residence or apartment abroad;
- move family or center of life to another country;
- register locally or apply for a residence permit;
- work as a border commuter between two countries;
- combine a longer workation with productive work.
The 183-day rule is just one checkpoint. It does not replace a complete residency test or analysis of actual taxation rights.
Important distinctions
Tax residence answers the question of where the person is assigned for tax purposes. The Tax liability for remote work, on the other hand, deals with whether specific working days abroad can trigger taxable income there. Withholding tax describes the withholding of taxes at source, for example by employers or other paying agents. Permanent establishment risk does not primarily concern the individual's private tax position, but rather a possible corporate tax risk of the employer.

Frequently asked questions
Are you automatically a tax resident if you are abroad for 183 days?
Not automatically. Many countries use days of stay as a criterion, but place of residence, center of life, family and national rules can also be decisive.
Can a person be a tax resident in two countries?
Yes. It is then necessary to check whether a double taxation agreement assigns residence to a country for treaty purposes.
Does HR have to decide tax residency itself?
HR should record the case properly and pre-check it. In complex cases, the final tax assessment should be carried out by tax, payroll or external advice.
