How do you stay compliant with both Dutch and Bulgarian employment law?

Staying compliant with both Dutch and Bulgarian employment law requires maintaining two separate legal frameworks simultaneously, each with its own contract requirements, payroll obligations, and statutory entitlements. For companies operating across both jurisdictions, the practical answer is to treat each country as a distinct compliance environment rather than attempting to apply a single unified policy. The sections below address the most common questions HR leaders and operations directors face when managing a workforce that spans the Netherlands and Bulgaria.

Which employment rules apply when staff work across the Netherlands and Bulgaria?

When staff work across the Netherlands and Bulgaria, the employment rules of the country where the work is physically performed generally take precedence. Dutch employment law governs employees based in the Netherlands, while Bulgarian labour law applies to those working in Bulgaria. If an employee is seconded temporarily from one country to the other, the host country’s mandatory protections typically apply for the duration of that posting.

This distinction matters because both countries are EU members, and EU Posted Workers Directive rules apply when employees are temporarily sent to work in another member state. The directive ensures that posted workers receive at least the host country’s minimum wage, working time limits, and health and safety protections, regardless of which country’s contract they hold. However, social security contributions follow different rules and are often governed by EU Regulation 883/2004, which determines which country’s social security system applies based on where the employee habitually works.

For companies managing permanent headcount in both countries, the cleaner approach is to employ workers under the legal framework of their country of work from day one, rather than relying on posting arrangements that carry their own compliance conditions and time limits.

What are the key differences between Dutch and Bulgarian labour law?

The key differences between Dutch and Bulgarian labour law lie in areas such as minimum wage levels, notice periods, dismissal protections, and the role of collective labour agreements. The Netherlands has one of the most protective and procedurally complex employment frameworks in the EU, while Bulgaria operates a more employer-flexible system, though both impose meaningful obligations on employers.

Dismissal and termination rules

In the Netherlands, dismissing an employee is a structured legal process. Employers must either obtain approval from the Dutch Employee Insurance Agency (UWV) for economic dismissals or go through the cantonal court for dismissals on personal grounds. Employees with more than two years of service are entitled to a statutory transition payment. Bulgaria, by contrast, permits a broader range of dismissal grounds and generally requires shorter procedural steps, though notice periods and severance entitlements still apply under the Bulgarian Labour Code.

Collective labour agreements and working conditions

The Netherlands has an extensive system of sector-specific collective labour agreements (CAOs) that impose conditions above the statutory minimum, covering pay scales, working hours, and benefits. Employers must determine whether a CAO applies to their sector and comply accordingly. Bulgaria also has collective agreements, but their coverage is less pervasive, and baseline statutory conditions under the Labour Code tend to be the primary reference point for most employers.

How does payroll compliance work when employing in both countries?

Payroll compliance when employing in both the Netherlands and Bulgaria requires running two entirely separate payroll processes, each aligned with the respective country’s tax authority, social security system, and reporting cadence. There is no unified cross-border payroll mechanism: each jurisdiction must be managed independently.

In the Netherlands, employers must register with the Dutch Tax and Customs Administration (Belastingdienst), withhold wage tax and national insurance contributions, and adhere to the Dutch payroll tax return schedule. Dutch payroll is also subject to the Wage Tax Act and, where applicable, sector-specific premium rates. Employers must also account for the 30% ruling for qualifying international employees, which can reduce taxable income for eligible non-Dutch hires.

In Bulgaria, payroll is administered through the National Revenue Agency (NRA). Employers withhold personal income tax at a flat rate and contribute to social and health insurance funds. Bulgarian payroll cycles and reporting deadlines differ from those in the Netherlands, and the contribution rates (both employer and employee portions) are structured differently. Companies employing in both countries need either dedicated local payroll capability in each market or a trusted third-party provider with in-country expertise.

What employment contracts are legally required in the Netherlands and Bulgaria?

Both the Netherlands and Bulgaria legally require written employment contracts, but the mandatory content differs between the two jurisdictions. In both countries, verbal agreements may technically form a contract, but written documentation is a legal obligation and a practical necessity for compliance.

In the Netherlands, the EU Transparent and Predictable Working Conditions Directive (implemented locally) requires employers to provide employees with a written statement of their core employment terms within one week of starting work. Dutch contracts must specify the nature of the role, working hours, salary, notice periods, and the applicable collective labour agreement if one applies. Fixed-term contracts in the Netherlands are subject to the chain rule (ketenregeling): after three consecutive fixed-term contracts or a total duration exceeding three years, the contract automatically converts to permanent employment.

In Bulgaria, the Labour Code requires a written contract before the employee begins work, and employers must register the contract with the National Revenue Agency within three days of signing. Bulgarian contracts must include the job title, remuneration, working hours, and place of work. Fixed-term contracts in Bulgaria are permitted but are limited in duration and scope, and misuse of fixed-term arrangements can result in the contract being reclassified as indefinite by a labour court.

When should a company use an employer of record for cross-border hiring?

A company should use an employer of record (EoR) for cross-border hiring when it needs to employ staff in a country where it has no registered legal entity, lacks local HR and payroll infrastructure, or wants to move quickly without the time and cost of setting up a subsidiary. The EoR becomes the legal employer of record, handling contracts, payroll, tax, and compliance, while the client company retains day-to-day management of the employee’s work.

For companies hiring in the Netherlands specifically, the EoR model is particularly relevant in several scenarios:

International businesses testing the Dutch market without committing to entity formation
Companies needing to employ a highly skilled migrant who requires IND-recognised sponsorship
Organisations that want to engage freelancers compliantly following stricter bogus self-employment enforcement
Businesses that need flexible, scalable headcount without long-term employment liability

The EoR model also applies when a company already has operations in one country (say, Bulgaria) and wants to hire locally in the Netherlands without duplicating its legal and HR setup. Rather than navigating Dutch employment law, payroll registration, and social security obligations from scratch, the EoR absorbs that complexity and delivers a compliant employment structure from day one.

What are the biggest compliance risks of getting dual-jurisdiction employment wrong?

The biggest compliance risks of mismanaging dual-jurisdiction employment include worker misclassification, incorrect social security allocation, non-compliant contracts, and failure to apply mandatory local employment protections. Each of these carries financial penalties and, in some cases, retroactive liability that can significantly exceed the cost of getting compliance right from the outset.

In the Netherlands, the enforcement of bogus self-employment rules has intensified since 2025. Companies that engage workers as freelancers when the relationship resembles employment (particularly where the worker has fewer than three clients) risk being classified as the de facto employer by the Dutch tax authority. This can trigger backdated wage tax, social premium payments, and fines. The risk is compounded when those workers are also operating across borders, as the question of which country’s social security system applies adds another layer of exposure.

In Bulgaria, common risks include failing to register contracts with the NRA within the required timeframe, misapplying fixed-term contract rules, and underpaying social insurance contributions. Bulgarian labour inspectors conduct audits and can impose penalties for procedural non-compliance even where the substantive employment relationship is sound.

Across both jurisdictions, applying the wrong country’s law (for example, using a Dutch contract template for a Bulgarian-based employee) is a structural error that can invalidate key contract terms and expose the employer to claims under local law. Dual-jurisdiction employment requires deliberate, country-specific legal architecture, not a one-size-fits-all approach.
