When does tax liability begin upon immigration?
In an immigration situation, it is not sufficient for the taxpayer to acquire a permanent residence in order to become fully tax liable. Full tax liability does not begin until the individual also takes up residence in Denmark. Thus, tax liability is triggered by a combination of having a home and residing in the country.
The residence condition is particularly assessed based on the purpose of the stay. The taxpayer does not become fully tax liable if they remain in Denmark continuously for vacation or similar purposes for a maximum of 3 months, or if the total stay amounts to up to 180 days within a 12-month period.
What does “vacation or similar” mean?
It is given that work does not qualify as vacation or similar. Therefore, a taxpayer who has a permanent residence available and works in Denmark will, as a rule, become fully tax liable.
This is a difficult distinction that requires an examination of the taxpayer’s behavior.
Does one become fully tax liable by responding to emails, phone calls, or similar while staying or vacationing in Denmark?
The case law in this area is neither precise nor consistent. It requires a specific assessment in which various factors must be considered. For example, many taxpayers reside abroad but serve as board members in Danish companies. These individuals travel to Denmark multiple times per year to attend board meetings or similar.
As a general rule, a taxpayer does not become fully tax liable by participating in board meetings in Denmark. However, this conclusion may change if, for instance, the person stays in their summer house while engaging in such business activities.
The Danish Tax Agency has accepted that a taxpayer may sporadically and to a limited extent use their phone and/or email for business purposes while having a residence in Denmark, without becoming fully tax liable. It is important to emphasize, however, that the taxpayer will become fully tax liable if they conduct business meetings (e.g., a board meeting) in their summer house.
Furthermore, the Danish Tax Agency places particular importance on the fact that the taxpayer does not become fully tax liable if they stay at a hotel in connection with board meetings and do not overnight in their summer house. This creates a clear distinction between “vacation or similar” and “business activities.”

Tax consequences
If the Danish Tax Agency determines that the taxpayer has become fully tax liable without having properly reported this, it may result in an extraordinary tax assessment, by which the tax authorities can go back up to 10 years. In addition, the taxpayer may face fines or imprisonment for tax evasion, depending on the circumstances and the extent of the violation.
