Global mobility services for compliance in Denmark
When an employee crosses the Danish border, whether arriving or departing, tax residency, social security, payroll registration, and authority reporting obligations follow immediately. The sequence matters. An SE number must exist before the first payslip. A1 certificates under EU Regulation 883/2004 must reflect the actual work pattern. RUT registration must be completed before posted work begins.
We establish the tax and social security position that governs all of it, and we run the payroll on that position. The same team that analyses the situation handles the execution. Nothing is handed off.
When this applies
- Employing staff based in Denmark without a Danish legal entity
- Sending Danish employees to work abroad on assignment or posted worker arrangements
- Receiving international employees into Denmark
- Expanding into Denmark for the first time and unsure what registration obligations apply before work begins
- Managing a cross-border workforce where the current payroll setup was not built for the complexity it now carries
One position. Everything built on it.
Most compliance problems in cross-border employment come from one source: the tax and social security position is set by an adviser, and the payroll is run by a separate bureau. When the position is wrong, the payroll is wrong. When the payroll is wrong, the error compounds across every reporting period, and the Danish tax authorities typically find it at year-end, not when the mistake was made.
We do not separate advisory from execution. We establish the cross-border position (the legal and tax basis on which salary calculations, eIndkomst reporting, AM-bidrag deductions, and social security contributions all rest) and we run the payroll against it. If circumstances change mid-year, we adjust the position and the payroll at the same time. Year-end becomes a confirmation, not a correction exercise.
What we cover
Each service below operates as part of a connected compliance structure. Every entry links to a dedicated page with specific thresholds, deadlines, and a breakdown of what we handle on your behalf.
Advisory and execution combined in one structure
The Crossbord Solution
The Crossbord Solution is not a bundle of separate services; it is a single integrated structure in which the tax and social security position informs the payroll from day one, and compliance is managed in real time throughout the year. It replaces the fragmented model in which an adviser sets a position, a payroll bureau runs numbers on assumptions, and the gap between the two becomes a liability. We design the structure, run the payroll on it, and handle authority communication directly. The employer does not have to coordinate between multiple providers or reconcile conflicting outputs at year-end.

How do we prepare a new international hire for the Danish tax system?
Tax briefing
The Danish tax system is unfamiliar territory for most internationally mobile employees. The payslip structure is different, the fields and deductions are in Danish, MitID registration is required before the employee can access the online tax portal (TastSelv Borger), and missing early steps creates problems that fall back on the employer. The tax briefing is a structured introduction: we walk the employee through what a Danish payslip contains and what each field means, how to set up MitID, and how to navigate TastSelv Borger. We conduct a briefing interview to identify the employee’s specific circumstances, and we produce a written summary covering the facts of their tax status, the assumptions underlying our assessment, and the actions required. The employer does not have to explain the Danish system to the employee or field questions about payslips, deductions, or online registrations.

What is the full tax exposure across this situation, and what is the recommended approach?
Tax analysis and compliance advisory
Where a tax briefing covers a specific situation, a tax analysis covers the full picture: residency status across jurisdictions, applicable double taxation agreements (DTAs), permanent establishment risk, social security coordination rules, and available optimisation options. The output is a written analysis and an approved action plan. This service is typically the entry point for organisations that have not previously mapped their cross-border exposure and need a documented basis before any payroll or compliance structure is designed. The employer does not have to determine which questions to ask; we identify the exposure from the facts.

Who runs payroll when the employer has no Danish entity?
Cross-border payroll
A foreign employer paying a Danish-resident employee must register an SE number, report salary via eIndkomst, deduct AM-bidrag at 8%, and apply the correct skattekort. Standard payroll bureaus do not hold the tax analysis to run this correctly. We do both. The employer does not need a separate payroll provider or a Danish accounting firm.

Which country's social security system applies to our employee working across borders?
Social security coordination and A1 certificates
Under EU Regulation 883/2004, an employee can only be subject to the social security legislation of one member state at a time. An A1 certificate documents which state that is. Without one, an employee working across EU borders can face dual contributions. We handle the application, the coordination with the relevant authorities, and the documentation. The employer does not have to navigate the liaison process between national authorities.

Does our new hire qualify for the Danish flat-rate tax scheme?
The inbound expat tax regime (forskerskatteordningen)
Qualifying employees pay a flat 27% tax rate plus AM-bidrag (8%) for up to 84 months, in place of standard progressive rates that can reach 52.07%. To qualify, the gross monthly salary must meet the minimum threshold (DKK 65,400 in 2026, reduced from DKK 78,000 in 2025) and the employee must not have been tax resident in Denmark within the preceding ten years. The reduced 2026 threshold applies to new employments entered into from the 1st of January, 2026; employees already on the scheme under 2025 or earlier terms continue under those rules. The application must be submitted within one month of the employee’s first working day. We assess eligibility, prepare the application, and monitor compliance for the full duration of the scheme.

Has our activity in Denmark created a corporate tax liability?
Permanent establishment analysis
A project, a visiting sales employee, or an employee working from home in Denmark can trigger a permanent establishment (PE) under Danish tax law or the applicable DTA, creating Danish corporate income tax liability for the foreign entity. The threshold is fact-specific. We analyse the work pattern, the contractual structure, and the DTA provisions before the Danish tax authorities conduct their own assessment. The employer does not have to determine the risk or rely on a general rule of thumb.

What must a foreign company register before starting work or employing staff in Denmark?
Foreign company registration in Denmark
Foreign companies employing Danish-resident staff, or sending workers to Denmark, are subject to registration requirements that apply before work begins. These include SE number registration for payroll purposes, CVR number registration where a taxable presence exists, and RUT registration for posted workers under the Posted Workers Act. Late RUT registration triggers fines from the Danish Working Environment Authority (Arbejdstilsynet). We handle all registrations and confirm the correct sequence before the first working day.
Read about foreign company registration.
What needs to be reconciled at year-end for employees with Danish tax obligations?
Year-end reconciliation and tax filings
Employers must finalise eIndkomst reporting for the tax year by the 20th of January, with a correction window open until the 15th of February before employees’ annual tax statements (årsopgørelser) are generated; errors found after that point require a formal correction request to the Danish tax authorities, not a simple resubmission. We reconcile payroll data against the eIndkomst position throughout the year, not only in January, so the correction window becomes a final check rather than the point at which discrepancies first surface.
Read about year end reconciliation.
What compliance steps have to be completed before an employee moves to Denmark?
Relocation support
The Danish compliance clock starts at arrival. CPR number registration, skattekort application, and social security determination must all be in place before the first payslip. We prepare the compliance side of the move in advance of the employee’s start date, coordinating with the payroll from day one. The employer does not have to manage the registration sequence or track the dependencies between steps.
Read about relocation support.
What work authorisation does our employee need to work legally in Denmark?
Immigration and work permit support
Employees from outside the EU and EEA require a work permit before starting employment in Denmark. The permit type depends on salary level, job category, and duration. We handle the application and track the timeline against the start date. The employer does not have to determine permit eligibility or manage the submission process with the Danish Immigration Service (Styrelsen for International Rekruttering og Integration).

What are the tax obligations for offshore or oil and gas operations in Danish waters?
Hydrocarbon tax compliance
Profits from oil and gas extraction on the Danish continental shelf are taxed under the Hydrocarbon Tax Act at 52%, on top of the 25% ring-fenced corporate rate, for an effective rate of 64%. The day-counting rules that determine when an individual employee becomes taxable vary by treaty: enterprises domiciled in the United Kingdom are taxed on offshore work from day one, while employees resident in other Nordic countries become liable only after 30 days offshore within a 12-month period. We handle the compliance structure for offshore employers and contractors, including the payroll calculations specific to the hydrocarbon regime. The employer does not have to navigate the overlap between hydrocarbon tax rules and standard Danish payroll requirements.
Book a meeting to learn more about hydrocarbon tax compliance.
What are the tax and reporting obligations when workers are leased across borders?
Labour leasing advisory
Cross-border leasing of labour force brings attention to the Danish hiring-out-of-labour scheme (arbejdsudleje). The obligation to withhold tax, under the scheme, rests with the party (the end user of the labour) that has a permanent establishment in Denmark, regardless of ownership; a foreign company running a project or branch in Denmark can therefore carry this obligation even though it is not itself Danish. Once it applies, the liable party must withhold 8% labour market contributions plus a 30% hiring-out tax (an effective 35.6% of the worker’s gross wages), and remains liable for any unpaid amount even after the foreign supplier has already been paid in full. We determine which side carries the obligation, apply the correct tax treatment, and handle the reporting, so you do not have to work out where the Danish or foreign line falls.
Book a meeting to learn more about labour leasing obligations.
What we do not cover
We do not offer employment law advice, HR policy design, or employment contract drafting; an employment lawyer covers those. We do not handle physical relocation logistics such as housing or moving. We do not provide corporate tax structuring or advice on Danish entity formation beyond the registration obligations that arise from cross-border employment. If you are unsure whether your situation falls within our scope, the fastest way to find out is to book a meeting.
