Polish Temp Agency Danish Licence: Vikarbureau Checklist 2026

If your Polish temporary work agency places workers on Danish soil, the question of whether you need a Danish vikarbureau licence is not optional reading, it is a legal obligation you must resolve before your first worker crosses the border. Denmark's rules on temporary staffing agencies, rooted in the framework commonly referred to as LOV 89 and supervised by Arbejdstilsynet (the Danish Working Environment Authority), draw a clear line between agencies that must register and those that fall outside the scope. Getting that line wrong exposes both the agency and the Danish user company to serious liability.

Why the Licence Question Matters in 2026

Danish labour market enforcement has grown steadily more systematic in recent years. Arbejdstilsynet conducts workplace inspections and cross-checks registration data against tax records held by SKAT. When an unregistered foreign agency is found placing workers, the consequences fall not only on the agency itself but also on the Danish construction firm or manufacturer that hired those workers. For Polish agencies operating under Polish law, governed by the Kodeks Pracy and supervised domestically by PIP (Państwowa Inspekcja Pracy), the Danish requirements add a second compliance layer that cannot simply be ignored on the grounds that the agency is already licensed at home.

Understanding the trigger conditions is therefore the first practical step. The sections below walk you through the process in the order that makes most operational sense.

Step 1: Check Whether Your Activity Triggers the Licence Requirement

The Danish rules on vikarbureau registration apply when an agency hires out workers to a user company in Denmark and those workers remain employed by the agency rather than the user company. If your Polish agency sends workers to a Danish firm that directs their daily work while your agency continues to pay their wages, you are almost certainly operating as a vikarbureau under Danish law.

Two situations that do NOT typically trigger the Danish vikarbureau requirement are: genuine subcontracting, where your agency delivers a finished service or result rather than lending labour, and direct cross-border posting for a fixed project where the worker remains fully under your agency's direction. However, the distinction between posting and hiring-out is one that Danish and EU authorities examine carefully. The Court of Justice of the EU has addressed the substance-over-form principle in labour mobility cases on multiple occasions, and Arbejdstilsynet applies similar logic during inspections. If in doubt, treat your operation as vikarbureau activity and seek registration.

For agencies already managing working-time compliance, the related obligations around record-keeping are significant. Our article on Task-Based Leave & Time Records in Denmark 2026: Agency Risks explains how leave and time-record rules intersect with agency status.

Step 2: Gather the Required Documents

Before touching any application form, assemble your documentation. Danish authorities expect to see evidence that your agency is a legitimately constituted business with real operational capacity. At a minimum you will need:

1. A current extract from the Polish National Court Register (KRS) or the Central Register of Economic Activity (CEIDG), translated into Danish or English.
2. Proof of your Polish agency licence issued under Polish law, if applicable, Polish temp agencies operating under the Ustawa o zatrudnianiu pracowników tymczasowych should have this on file.
3. A Danish CVR number, which you obtain by registering your business with the Danish Business Authority (Erhvervsstyrelsen) before or alongside the vikarbureau application.
4. Documentation of your registered address or representative in Denmark, if required by the specific registration pathway.
5. Evidence of social security coverage, typically an A1 certificate issued by ZUS (Zakład Ubezpieczeń Społecznych) for each posted worker, confirming they remain in the Polish social security system during their assignment.

Tax obligations run parallel to registration. Polish agencies must also notify SKAT of their activity and, depending on the length and nature of assignments, may need to withhold Danish tax. Our guide on Withholding Tax in Denmark for Polish Temp Workers 2026 covers this in detail.

Step 3: Complete the Application Forms via the Official Portal

Arbejdstilsynet manages vikarbureau registration through its online portal. The starting point for foreign agencies is the Arbejdstilsynet website (at.dk), where you can find the current registration forms and guidance notes in Danish. For agencies unfamiliar with Danish administrative language, the guidance published by the Danish Ministry of Employment (bm.dk) provides broader context on the legal framework governing temporary work.

Fill out the forms completely. Partial applications are a common cause of delay. Pay particular attention to the sections describing the nature of your activity: be precise about whether you are hiring out workers, posting workers, or doing both, as each may be treated differently.

Step 4: Submit and Confirm Receipt

Once your application is complete, submit it through the designated channel, currently the digital portal linked from at.dk. Keep a dated confirmation of submission. If you are also registering for Danish VAT or employer obligations with SKAT, do this in parallel rather than sequentially; waiting for one approval before starting the next adds weeks to your timeline unnecessarily.

For agencies managing larger workforces, the administrative burden of simultaneous registrations across multiple Danish clients is substantial. The practical tools available for that scale of operation are discussed in our piece on Digital Time Tracking for Agencies Sending 50+ Workers to Denmark 2026.

Step 5: Await the Decision and Plan for the Interim Period

Processing times vary. During the waiting period, your agency should not assume that submission equals authorisation. If you have workers already on assignment in Denmark, make sure your Danish user company is aware of the pending registration status. Danish user companies bear their own compliance responsibilities and will want written confirmation that your application is in progress.

Once the licence is granted, store the registration certificate securely and include the registration number in all contracts with Danish user companies. Arbejdstilsynet inspectors may request it during site visits.

Common Mistakes to Avoid

The most frequent error Polish agencies make is assuming that their domestic PIP licence or Kodeks Pracy compliance automatically satisfies Danish requirements. It does not. The two systems run in parallel, and Danish law makes no exception for agencies already regulated abroad.

A second common mistake is failing to obtain A1 certificates from ZUS before workers begin their assignments. Without a valid A1, the worker's social security status is ambiguous, which creates problems both for the worker and for the agency's registration dossier.

A third pitfall is misclassifying the work relationship to avoid the vikarbureau label. As noted above, Danish and EU authorities look at economic reality. A hypothetical example: an agency that formally structures its contracts as service agreements but in practice sends workers who take daily instructions from the Danish client's site manager is likely to be reclassified as a vikarbureau on inspection, regardless of what the paperwork says.

Actionable Advice for Polish Agencies Operating in Denmark

Start the registration process before your first worker begins an assignment in Denmark, not after. Compile your KRS extract, ZUS A1 certificates, and Danish CVR number as a standing package that you can update and reuse for each new Danish client. Review your contracts annually against the current Arbejdstilsynet guidance, because the administrative requirements can change. And maintain open communication with your Danish user companies, they are co-responsible for ensuring that the agency they work with is properly registered, and a transparent relationship protects both sides when inspectors arrive.
