How are foreigners insured in the European Union (EU)?
Social security for foreigners in the European Union is a complex but well-coordinated system that ensures the protection of citizens’ rights, regardless of their country of origin or residence. For foreigners working in the EU, it is of utmost importance to be familiar with the regulations and laws to avoid financial penalties or gaps in coverage. In this article, we will examine the key points and specifics of social security for foreigners in the EU.
What are the basic rules of social security in the EU?
The „one country – one insurance“ principle
The fundamental rule established by Regulation (EC) No 883/2004 is that individuals can be insured in only one EU member state. This is determined based on the place where they carry out their work activity. This principle is known as “lex loci laboris”.
- What does this mean? If you work in a given country, for example France, you are subject to the French social security system, regardless of where you live or where your employer is located.
What does social security cover?
Social security in the EU includes:
- Pension contributions.
- Health insurance.
- Unemployment insurance.
- Contributions for work-related accidents and professional diseases.
These contributions ensure protection in case of illness, old age, or loss of income, while simultaneously avoiding double insurance.
How is the country where you must be insured determined?
Insurance according to the type of activity
To determine which country is responsible for your social security, it is important to consider:
- The place where the activity is performed.
- The type of employment – employed or self-employed person.
- The presence of cross-border activity.
- Employed persons: If you are employed by a company, your insurance is usually in the country where you work.
- Self-employed persons: They must be insured in the country where they carry out their primary activity.

Example of cross-border insurance
If you work in two countries, for example Germany and Austria, and you generate at least 25% of your income in one of them, that country will be your primary insurance country.
How are individuals with multiple employers insured?
Foreigners who work for more than one employer in different EU countries must pay special attention to social security rules. The general rule states that insurance is handled in the country where the employer associated with the main activity has its headquarters. If the activity is evenly distributed, the A1 document will determine the country where the insurance contributions are due. This is particularly important for avoiding double insurance and penalties.
A1 Document: What is its role?
What is the A1 document?
The A1 document is an official certificate indicating which EU member state is responsible for your social security. This document is essential for people who work in more than one country or whose work activity is cross-border.
How to obtain an A1 document?
To obtain an A1 document, you must submit an application to the competent institution in the country where you perform a significant part of your activity. For example, if you work primarily in Bulgaria, you must submit your documents to the National Revenue Agency (NRA).
The A1 document is valid for a specific period and must be renewed if your situation changes.
What should company managers know?
Social security for foreigners – company owners
If you are a foreigner who is an owner and manager of a company in Bulgaria but you carry out your activity in another EU country, it is important to know the following:
- If your entire activity is outside Bulgaria, contributions are paid in the country where you work.
- If part of the activity is carried out in Bulgaria, you must comply with local social security legislation.
Example: A manager of a Bulgarian company who lives and works in Italy will be subject to insurance according to Italian laws.
How to optimize your social security as a manager?
To avoid mistakes, it is recommended to consult with experts who are familiar with both Bulgarian and European legislation. ABC Consult Accounting Firm can help you analyze your situation and prepare the necessary documents – contact us.
What are the obligations of self-employed persons?
Basic rules for the self-employed
Self-employed persons must be insured in the country where they carry out their activity. They choose the income on which to be insured, but within the minimum and maximum thresholds set by local legislation.
How is the country for insurance determined?
If you practice an activity in more than one country, the primary insurance country will be the one in which:
- You work a significant part of your time.
- You generate your primary income.
