Can a Bulgarian freelancer invoice a Dutch company without a work permit?

A Bulgarian freelancer can invoice a Dutch company without a work permit. As an EU citizen, a Bulgarian national has the right to provide services freely across EU member states, including the Netherlands, without requiring prior authorisation from Dutch immigration authorities. However, the situation changes significantly depending on whether the freelancer is working remotely from Bulgaria or physically present in the Netherlands, and how the commercial relationship is structured. The sections below address the most common questions that arise for both the freelancer and the Dutch company engaging them.

Do Bulgarian citizens need a work permit to work in the Netherlands?

Bulgarian citizens do not need a work permit to work in the Netherlands. Bulgaria is a full EU member state, and EU freedom of movement applies in full, meaning Bulgarian nationals have the right to live, work, and provide services in the Netherlands under the same conditions as Dutch citizens. No prior approval from the IND or UWV is required.

This applies whether the Bulgarian national intends to take up employment, establish a self-employed business, or provide freelance services. The distinction that matters legally is not nationality but the nature of the work arrangement. A Bulgarian freelancer invoicing a Dutch client as a genuinely independent contractor occupies a different legal position than a Bulgarian employee working under a Dutch employment contract.

If a Bulgarian national plans to live in the Netherlands for more than four months, they must register with the local municipality and obtain a BSN (citizen service number). For shorter engagements conducted primarily from Bulgaria, no Dutch registration is required.

Is invoicing a Dutch company the same as working in the Netherlands?

No. Invoicing a Dutch company is not the same as working in the Netherlands. A Bulgarian freelancer who performs all their work remotely from Bulgaria and invoices a Dutch client is providing cross-border services, not working within Dutch jurisdiction. Dutch employment law and Dutch work authorisation requirements do not apply in this scenario.

The legal and tax situation shifts when the freelancer begins spending significant time physically in the Netherlands to deliver the work. At that point, questions of tax residency, social insurance contributions, and the classification of the working relationship become relevant for both parties.

One critical nuance concerns the definition of genuine self-employment. Dutch authorities, particularly the Belastingdienst (Dutch tax office), scrutinise freelance arrangements carefully. If a Bulgarian freelancer works exclusively or predominantly for one Dutch client, operates under that client’s direct supervision, and has no real entrepreneurial independence, the arrangement may be reclassified as disguised employment. This is the bogus self-employment issue that gained sharper teeth following the stricter enforcement of the DBA Act (Wet DBA) in 2025. Both the freelancer and the Dutch company carry risk if the arrangement does not reflect genuine independent contracting.

What taxes apply when a Bulgarian freelancer invoices a Dutch client?

When a Bulgarian freelancer invoices a Dutch company from Bulgaria, Dutch income tax generally does not apply. The freelancer is taxed in their country of residence, which is Bulgaria, under Bulgarian tax rules. The Dutch company does not withhold wage tax or social premiums on freelance invoices from abroad.

However, VAT treatment requires attention. Under EU VAT rules, B2B services supplied by a Bulgarian freelancer to a Dutch company are subject to the reverse charge mechanism. The Dutch company accounts for VAT in the Netherlands, and the Bulgarian freelancer does not charge Dutch VAT on the invoice. The freelancer must still comply with Bulgarian VAT obligations if their turnover exceeds the relevant Bulgarian threshold.

If the Bulgarian freelancer becomes a tax resident of the Netherlands, the picture changes entirely. Dutch residents are taxed on their worldwide income, and the Belastingdienst would expect income tax filings, social premium contributions, and potentially registration as a ZZP (zelfstandige zonder personeel), the Dutch self-employed category. The 30% ruling may offer some relief for qualifying highly skilled migrants, though this applies to employees rather than independent contractors in most cases.

Does the Dutch company have any legal obligations toward the freelancer?

When engaging a Bulgarian freelancer on a genuine independent contractor basis, a Dutch company’s obligations are limited compared to those owed to an employee. There is no obligation to provide holiday pay, sick pay, pension contributions, or notice periods that would apply under a Dutch employment contract.

That said, the Dutch company is not entirely without responsibility. Key obligations include:

  • Correct classification: The company must ensure the engagement genuinely qualifies as independent contracting. If it does not, the Belastingdienst can impose back taxes, social premiums, and penalties on the company as the deemed employer.
  • Written agreement: A clear service agreement defining the scope of work, deliverables, fees, and the independent nature of the relationship is essential. Model contracts approved by the Dutch tax authority offer a degree of protection.
  • GDPR compliance: If the freelancer processes personal data on behalf of the Dutch company, a data processing agreement is required under GDPR, regardless of where the freelancer is based.
  • Payment terms: Dutch law sets a maximum payment term of 30 days for large companies paying small suppliers, which may apply depending on the company’s size and turnover.

The risk of misclassification is the most significant compliance concern. Dutch companies that engage freelancers with fewer than three clients, or who work under close supervision with no genuine entrepreneurial independence, face the real possibility of being treated as the legal employer, with all the financial and administrative consequences that entails.

What happens if the freelancer works on-site in the Netherlands?

If a Bulgarian freelancer works on-site in the Netherlands, the legal and tax situation becomes more complex. Physical presence in the Netherlands to deliver services can trigger Dutch tax obligations, depending on the duration and frequency of the visits. Short occasional visits for meetings or project milestones are unlikely to create tax residency, but extended or regular presence may.

From a work permit perspective, EU freedom of movement still applies. A Bulgarian national does not need a work permit to work on-site in the Netherlands, regardless of duration. However, stays exceeding four months require municipal registration and a BSN.

The more pressing concern is the misclassification risk. On-site working arrangements, particularly those involving integration into the client’s team, use of the client’s equipment, and day-to-day supervision by the client’s managers, are precisely the conditions that Dutch authorities associate with disguised employment. A freelancer who effectively functions as an embedded team member, regardless of how the invoicing is structured, is exposed to reclassification.

For Dutch companies, hosting a Bulgarian freelancer on-site under a straightforward invoicing arrangement without addressing these structural risks is a compliance gap that warrants legal review.

When should a Dutch company use an employer of record instead?

A Dutch company should consider using an employer of record when the freelance arrangement does not meet the criteria for genuine independent contracting, when the Bulgarian professional will be working primarily on-site in the Netherlands, or when the company wants to bring the individual into a compliant employment structure without the administrative burden of direct hiring.

An employer of record employs the individual on the client company’s behalf, handling payroll, contracts, tax deductions, social premiums, and all HR administration. This eliminates the misclassification risk entirely, because the worker is formally employed rather than engaged as a freelancer. For the Bulgarian professional, it also means access to the same employment rights and benefits as local Dutch employees.

This model is particularly relevant in scenarios where:

  • The freelancer works exclusively or predominantly for one Dutch client
  • The client directs the freelancer’s day-to-day work
  • The engagement is long-term and the line between contractor and employee has blurred
  • The Dutch company wants to test a working relationship before committing to a permanent hire
  • The Bulgarian professional intends to relocate to the Netherlands and needs a compliant employment structure
