Hiring Non-EU Workers in Bulgaria: An Employer Compliance Guide for 2026

Bulgaria's rules for hiring workers from outside the European Union sit at the intersection of three government bodies, and an employer who treats any one of them as an afterthought risks delays that push a hire back by months. The Ministry of Labour and Social Policy, through the Employment Agency, controls access to the labour market. The Migration Directorate, within the Ministry of Interior, controls entry and residence. The National Revenue Agency controls whether the employment relationship is properly taxed and insured once the person is working. None of these processes runs on its own; they are sequential, and a mistake early on cascades into every later step. For a company planning to bring in a third-country national in 2026, the practical question is rarely whether it is legal, but in what order, through which agency, and with what lead time. This guide walks through that sequence.

The Single Permit: Combining Work Access and Residence

Bulgaria, like most EU member states, has implemented the single permit procedure, which combines authorisation to work and authorisation to reside into one administrative track. For most standard employment cases this is the default route, running through the Migration Directorate with input from the Employment Agency rather than through two unconnected offices. The employer, rather than the employee, generally initiates the process:

• The employer files with the Migration Directorate or its regional offices, while labour market access is coordinated through the Employment Agency
• The Employment Agency reviews the position against the domestic labour market and issues its opinion, a step that has taken roughly two to four weeks in recent practice
• Once access is confirmed, the foreign hire applies for a national type D visa at a Bulgarian embassy or consulate, if not already legally present in Bulgaria
• After entering on the type D visa, the applicant finalises residence formalities with the Migration Directorate, including proof of health insurance and accommodation, before the physical residence document is issued

Because the steps span more than one authority plus a home-country consular stage, employers should plan for the full sequence, from filing to a document in hand, to take roughly two to four months, with complex cases running longer. Firms that assume a single-permit hire can be completed in a few weeks are usually the ones who end up with a candidate stuck abroad past their intended start date.

The Labour Market Test and Quota Limits

For standard single-permit cases, the Employment Agency typically requires evidence that the position was genuinely open to Bulgarian and EU candidates first. In practice this means a documented vacancy posting period, generally around two weeks, across recognised job platforms, plus a record of the recruitment effort and the business justification for hiring outside the EU labour pool.

Bulgaria also caps how much of a company's workforce can be third-country nationals, generally no more than 20 percent of average headcount, with a higher allowance, commonly cited around 35 percent, for small and medium enterprises. The Minister of Labour and Social Policy retains discretion to grant exceptions, which is why employers with concentrated non-EU hiring needs should check their ratio early rather than discover a quota problem mid-application.

Certain categories sit outside the standard test. The EU Blue Card, intra-corporate transfers, and seasonal work schemes each follow their own simplified procedures rather than the ordinary single-permit labour market test.

The EU Blue Card Route

Bulgaria operates the EU Blue Card for highly qualified third-country nationals, worth considering wherever the role and candidate profile fit, since it generally moves faster than the standard single permit and skips the labour market test.

To qualify, the applicant needs a binding job offer or contract for highly skilled work running at least six months, evidence of higher professional qualifications, sickness insurance, a clean criminal record, and confirmed housing in Bulgaria. The defining feature is a minimum salary threshold, set as a multiple of the national average gross salary and updated annually; employers should confirm the current figure with the competent authority or a local adviser rather than relying on any published number, since it changes every year. Permits are generally issued for up to five years, or for the contract length plus a short buffer where the contract runs shorter, subject to a statutory minimum duration. Applications go through the Migration Directorate's dedicated channels, including the government's electronic services portal, with review intended to stay within a set number of months from a complete filing.

National Revenue Agency: Tax and Social Security Registration

Work and residence authorisation only solves half the compliance question. Once a third-country national is entitled to work, the employer still has to register the employment relationship with the National Revenue Agency, an obligation that applies whether the employer is a Bulgarian entity or a foreign company employing staff in Bulgaria without a local subsidiary.

A foreign employer without an existing Bulgarian tax registration typically needs a service number from the National Revenue Agency before it can lawfully run payroll, obtained with an apostilled extract from the home-country commercial register, apostilled tax registration documents, and a formal application, all translated into Bulgarian by a certified translator.

Once registered, the employer's ongoing obligations include:

• Calculating and remitting social security and health insurance contributions on the employee's behalf, generally through a Bulgarian bank account
• Withholding monthly advance personal income tax on the employee's earnings
• Notifying the General Labour Inspectorate Executive Agency of the new hire within a short window, commonly cited as seven days
• Keeping the employment contract aligned with Bulgarian labour law once the employer has an active registration

Employers who skip or delay this registration step are the ones most likely to end up with a legally resident, work-authorised employee whose payroll cannot actually be run compliantly, defeating the purpose of the permit process itself.

Staying Compliant Through 2026

Bulgaria's system rewards employers who sequence the process correctly and penalises those who treat it as one application. Confirming the labour market and quota position before recruitment starts, choosing the right permit category rather than defaulting to the standard single permit, and having the National Revenue Agency registration in place before the first working day are the three decisions that most reliably keep a hire on schedule and compliant.

Nestlers Group supports employers through this sequence for hiring in Bulgaria. Our immigration route assessment work helps employers choose between the single permit, EU Blue Card, and other categories before an application is filed. Our work visa assistance covers the Employment Agency, Migration Directorate, and consular stages end to end, while our tax registration for foreign citizens and A1 certificate services address the National Revenue Agency and social security side once the permit is granted. For employers who prefer not to establish a Bulgarian entity, our Employer of Record in Bulgaria service can employ the worker locally and take on the payroll and compliance obligations directly, and our global mobility end-to-end management ties the process together for employers hiring across Bulgaria, Romania, and Serbia.
