Employer sanctions for illegal employment in the EU and in Croatia
Directive 2009/52/EC presumes an employment relationship of at least three months, and Croatia's Aliens Act sets fines of 1,500 to 3,000 euro per worker.
Directive 2009/52/EC set a common minimum of sanctions for employers who hire third country nationals without a legal right of stay. Its Article 6 presumes the employment relationship lasted at least three months, placing the burden of proof on the employer. In Croatia the matching offences sit in the Aliens Act, with fines of 1,500 to 3,000 euro per worker.
Three duties before the first working day
Article 4 of Directive 2009/52/EC sets three duties, and all three precede the work. The employer must require the worker to produce a valid residence permit or other authorisation of stay before employment begins. It must keep a copy of that document for at least the duration of the employment, available for inspection. And it must notify the competent authority of the member state of the hiring, within the period and in the manner that state prescribes.
Those three acts sound like paperwork, and in a dispute they are the only evidence. An employer that ran the check has the defence the directive provides. An employer that ran the check but kept no copy is, in practice, in the same position as one that checked nothing. What those checks look like by document type is set out in the piece on right to work verification checks.
Money, back pay and liability along the chain
Article 5 requires effective, proportionate and dissuasive financial sanctions that rise with the number of illegally employed workers. Article 6 adds what employers more often underestimate: an obligation to pay all outstanding remuneration, with a presumption that pay was at least the statutory minimum and that the relationship lasted at least three months, plus social security contributions and the cost of returning the worker.
Article 8 extends liability along the chain. A contractor of which the employer is a direct subcontractor, and in defined cases the main contractor, is liable for financial sanctions and outstanding payments where it knew of the illegal employment. On construction and shipbuilding projects with several tiers of subcontracting, that makes a subcontractor's paperwork the client's risk.
| Provision | What it requires | Who carries the consequence |
|---|---|---|
| Article 4 | Permit check, retained copy, notification to the authority | Employer |
| Article 5 | Financial sanctions rising with the number of workers | Employer |
| Article 6 | Back pay, three month presumption, return costs | Employer |
| Article 8 | Liability of the direct contractor and the main contractor | Contractor and client |
| Articles 9 and 10 | Criminal offences for the more serious forms | Employer and responsible person |
| Article 14 | Risk based inspections and annual reporting to the Commission | Member state |
Articles 9 and 10 move the serious forms into criminal law. Repeated infringements, larger numbers of workers, particularly exploitative working conditions, employing a person known to be a victim of trafficking, and employing a minor without legal stay must all be made criminal offences by member states.
How this reads in the Croatian procedure
The Aliens Act, in the version published in Narodne novine 55/2026, sets fines of 1,500 to 3,000 euro per third country national in Articles 247 and 250 for particular breaches of employer duties. The per worker basis matters more than the range: across a group of twenty workers, one breach multiplies twenty times.
Beyond the fine come consequences that do not appear in the penalty notice. An employer with a disorderly file struggles to obtain a positive opinion from the Croatian Employment Service for the next application, and the police administration decides on a complete application within 90 days at the latest under Article 91(8) of the Aliens Act, with a further 30 days in justified cases. A hiring cycle halted by an inspection loses a quarter rather than a few days. The accommodation rules that inspections check most often are set out in the piece on accommodation standards and the rent cap.
What an inspection is actually looking for
Article 14 of the directive obliges member states to run inspections based on risk assessment, in the sectors most exposed, and to report annually to the European Commission. That is why inspections concentrate on construction, hospitality, agriculture and logistics rather than spreading evenly across the economy.
A file that survives an inspection in any member state holds the same four things: a copy of the residence document with the date it was checked, evidence of the notification to the competent authority, an employment contract whose terms match the permit, and records of wages and contributions paid. How those duties fit together across a hiring cycle is set out in the piece on the employer compliance chain.
The 2009 directive is drafted to give a checking, documenting employer a defence, and to take the argument of ignorance away from one that does neither. A view of these duties by destination country sits on the employers page.
