However, at a certain point this activity may create a tax presence.
A tax presence means that the local tax authorities consider your business as local enough to tax you — even if you have no legal entity, branch, or registration. In tax treaties this is called a permanent estabishment, but the concept is broader.
If your activities create a tax presence, this can trigger obligations such as:
corporate income tax on locally attributable profits
local bookkeeping and reporting requirements
registration with tax authorities
penalties or retroactive tax assessments if risks are missed
The difficulty is that tax presence is not always obvious.
Many companies assume that “no company” automatically means “no tax”, which is not always correct.
Tax presence risks often arise when a company:
has employees or directors working from another country
uses local sales agents or representatives
carries out long-term projects or on-site activities
operates warehouses or fixed facilities
manages local operations from a home office
Whether these activities create a tax presence depends on how authorities apply these tax rules in practice.
Tax presence questions in Denmark are handled through a combination of tax administration and a well-defined appeals structure.
Guidance and practical rules for foreign businesses are published on skat.dk, including Denmark’s official page explaining permanent establishment for non-Danish businesses (link).
If a dispute arises, appeals are handled via the Danish Tax Appeals Agency (Skatteankestyrelsen), which prepares cases for the National Tax Tribunal (Landsskatteretten) (link), (link).
In practice, Danish assessments are highly fact-driven, with clear attention to whether activities in Denmark are commercially significant and sufficiently permanent.
Denmark’s permanent establishment guidance for non-Danish businesses provides practical examples and highlights that construction and development projects can create a permanent establishment depending on duration (often 6 or 12 months depending on the treaty) (link).
This is one of the more concrete and operational permanent establishment guidance pages among European tax authorities, and it is useful as a baseline for “where Denmark draws the line” in practice.
A frequently cited Danish illustration involves a foreign company hiring a Danish resident salesman who worked from a home office. The tax analysis focused on what the salesman actually did in Denmark, and whether those activities were merely preparatory or instead commercially significant for establishing the Danish market. The case is discussed as an example of how Danish authorities evaluate permanent establishment risk when a home office and local sales activity are involved (link).
The practical lesson from this case discussion is that Danish tax presence risk can increase quickly where local personnel move beyond lead generation and become functionally embedded in the sales process.
Home office permanent establishment has remained a live topic in Denmark. A recent practitioner note specifically addresses when a home office in Denmark may create a permanent establishment for foreign employers, reflecting increased attention to structural remote work arrangements (link).
In practice, Danish risk analysis typically turns on whether the home office is effectively used as a stable operating base for core business functions, rather than being incidental or purely convenience-based.
Scrutiny typically increases where employees or representatives are permanently based in Denmark, where local activity is commercially decisive (especially sales and customer management), where projects show continuity, or where a Danish home office functions as a stable base for the enterprise’s operations.
Denmark’s permanent establishment analysis is generally documentation-driven: what matters is the factual role of Danish-based activity in the overall business.
If a permanent establishment is established, Denmark may tax profits attributable to Danish activities and require local filings and documentation. Where the position is identified after the fact, retroactive assessments are possible and profit attribution can become the central discussion point.
In Denmark, incorporation often becomes the cleaner option once sales or operational activity is intended to be permanent, when Danish-based people perform functions close to value creation, or when the compliance and attribution burden of operating without a formal entity outweighs the flexibility of a remote structure. At that stage, incorporation typically provides clearer boundaries and more predictable compliance.
Across tax systems, the assessment of tax presence typically follows a consistent set of underlying principles:
Substance over legal form
Actual business activities and economic reality carry more weight than contractual labels or formal structures.
People and decision-making
Where key individuals work, negotiate, manage operations or make decisions is often decisive.
Continuity and regularity
Ongoing or recurring activities are treated differently from occasional or incidental involvement.
Economic value creation
Where value is created, managed or controlled is a central factor in tax attribution.
These principles explain why the absence of a legal entity does not automatically eliminate tax exposure.
Tax presence risk is most commonly associated with the following types of activities:
Employees or directors working structurally from another jurisdiction
Sales personnel or agents with decision-making authority
Long-term or recurring on-site projects
Fixed places of business such as offices, warehouses or workshops
Home offices used as a regular base for business operations
The decisive factor is rarely a single activity, but rather the combination, duration and functional role of these activities.
Certain activities are widely regarded as preparatory or auxiliary and typically do not, on their own, create tax presence:
Occasional business travel
Pure marketing or promotional activities
Independent agents acting in the ordinary course of their business
Short-term presence without operational continuity
Supporting functions without decision-making authority
Risk may still arise when these activities evolve or are combined with more substantive functions.
