Bulgarian Social Security Affiliation and Benefits

Published on April 29, 2026 and written by Cyril Jarnias

The Bulgarian Social Security System occupies a central place in the daily lives of the country’s residents, offering a complex yet essential structure for affiliation and benefit management. Although the legislative framework of this system has undergone several reforms over the years, with adjustments to improve its efficiency and accessibility, it continues to raise questions about its functioning and impact on citizens. This guide explores the various aspects of affiliation, revealing the rights and obligations that fall upon the insured, and examines the diverse benefits offered, ranging from family allowances to healthcare and retirement pensions. By highlighting current issues and challenges, this article aims to provide a clear and in-depth understanding of this essential pillar of social protection in Bulgaria.

Social Security System in Bulgaria: General Principles

Legal Framework and Responsible Bodies

The social security system in Bulgaria is based on a solid legal framework, aimed at protecting citizens against various social risks. The National Social Security Institute plays a central role in managing cash benefits, while the National Health Insurance Fund oversees healthcare. These bodies operate under the supervision of the Ministry of Labor and Social Affairs and the Ministry of Health respectively, ensuring effective coordination of social policies.

Types of Benefits and Eligibility Criteria

The Bulgarian social protection system covers a wide range of risks:

• Sickness and maternity
• Work accidents and occupational diseases
• Old age
• Disability
• Death
• Unemployment
• Family benefits

Employees working more than five working days or at least 40 hours per month are generally eligible for benefits. Voluntary insurance options also exist for certain categories of workers, thus expanding the system’s coverage.

System Financing and Sustainability

The system’s financing relies primarily on social security contributions from employers and employees. The National Revenue Agency is responsible for collecting and monitoring these contributions. Contribution rates vary depending on the risks covered and the employment category. A Special Fund has been created to guarantee the financial stability of the pension system, acting as a reserve for periods of high demand.

Coverage and Inclusivity

The Bulgarian system aims for universal coverage, with approximately 86.4% of employed persons insured in 2019. Continuous efforts are made to reduce informal work and ensure that all workers, including those in new forms of employment, are covered by the pension system. The system also incorporates social solidarity mechanisms, offering pension credits for periods of career interruption, such as parental leave or military service.

Challenges and Perspectives

Faced with demographic challenges, the Bulgarian pension system has adopted a three-pillar approach: a pay-as-you-go system, a mandatory supplementary funded scheme, and a voluntary pillar. This structure aims to maintain a balance between financial sustainability and pension adequacy. The State plays a crucial role in forecasting the long-term balance between resources and expenditures, ensuring that the system can continue to meet its obligations to the elderly despite unfavorable demographic trends.

Affiliation and Contributions for Expatriates

Legal Framework and Eligibility Criteria

The Bulgarian social security system applies to all residents, including expatriates, who work more than five working days or at least 40 hours per month in Bulgaria. Bulgarian legislation provides for mandatory or voluntary insurance covering the risks of sickness-maternity, work accidents, occupational diseases, old age, disability, death, unemployment, and family benefits.

To be considered a tax resident and benefit from Bulgarian social security, an expatriate must meet one of the following conditions:

• Reside in Bulgaria for more than 183 days within a 12-month period
• Have a permanent address and their center of vital interests in Bulgaria
• Be assigned abroad by the Bulgarian state or a Bulgarian company

It is important to note that the provisions of double taxation agreements take precedence over Bulgarian legislation.

Administrative Steps for Affiliation

To affiliate with Bulgarian social security, expatriates must follow these steps:

• Register with the National Health Insurance Fund (Национална здравноосигурителна каса)
• Obtain a Bulgarian personal identification number
• Choose a general practitioner accredited by the National Health Insurance Fund
• Provide supporting documents for residence and employment in Bulgaria

It is recommended to be assisted by a local professional to facilitate these administrative procedures, which can be complex for non-residents.

Calculation of Social Contributions for Expatriates

In 2025, the overall social contribution rate in Bulgaria is 32.7% of gross salary, broken down as follows:

• 18.92% borne by the employer
• 13.78% borne by the employee

The monthly ceiling for the contribution base is set at 3,900 BGN (approximately 1,995 euros) for 2025.

The detailed breakdown of contributions is as follows:

• “Pensions” Fund: 19.8%
• Health Insurance: 8%
• Unemployment Insurance: 1%
• “Work Accidents and Occupational Diseases” Fund: between 0.4% and 1.1% depending on the sector of activity

Specifics for Different Categories of Expatriate Workers

For salaried expatriates, the employer is responsible for declaring and paying social contributions. They must affiliate the employee within 8 days following the start of the expatriation.

Self-employed workers must pay their own social contributions. In 2025, the minimum contribution base for the self-employed is set at 1,050 BGN per month (approximately 537 euros). They can choose to voluntarily insure themselves for the sickness-maternity risk.

For posted workers, the rules may vary depending on bilateral agreements between Bulgaria and the country of origin. In some cases, they may remain affiliated with their home social security system for a specified period.

Employer Obligations

The Bulgarian or foreign employer employing expatriates in Bulgaria has several obligations:

• Declare employees to the National Revenue Agency (Национална агенция за приходите)
• Calculate and withhold social contributions from employees’ gross salary
• Pay social contributions monthly (employer and employee share) to the National Social Security Institute
• Maintain up-to-date records of employees and their contributions

Failure to comply with these obligations can result in significant financial penalties for the employer.

Concrete Example

Let’s take the case of a French expatriate working as an employee in Bulgaria with a gross monthly salary of 5,000 BGN (approximately 2,556 euros):

• Employer’s share of contributions: 946 BGN (18.92% of 5,000 BGN)
• Employee’s share of contributions: 689 BGN (13.78% of 5,000 BGN)
• Total social contributions: 1,635 BGN (32.7% of 5,000 BGN)

The net salary after social contributions would therefore be 4,311 BGN (approximately 2,204 euros), excluding income tax.

This relatively advantageous social contribution system, combined with a 10% income tax rate, makes Bulgaria an attractive destination for expatriates seeking tax and social optimization.

Social Benefits Offered in Bulgaria

Overview of Social Benefits in Bulgaria

The Bulgarian social protection system offers a range of benefits aimed at supporting citizens in various situations. The main categories include family allowances, old-age pensions, unemployment benefits, and medical assistance. Although the country has made significant progress in recent years to improve its social safety net, challenges persist in terms of coverage and benefit adequacy.

Family Allowances

Bulgarian families can benefit from several types of allowances to support their children’s education. The monthly allowance for a child’s education is paid until the end of the child’s secondary education, with an age limit set at 20 years. This benefit is subject to means testing:

• For families whose gross monthly income per member does not exceed €363, the amount paid is 100% of the allowance
• For those whose income is between €363 and €414 per member, the amount is 80% of the allowance

• €26 per month for one child
• €56 for two children
• €84 for three children
• €89 for four children, with an increase of €10 for each additional child

For multiple births, each child receives a monthly allowance of €38.

Old-Age Pensions

The Bulgarian pension system is based on two mandatory pillars and one optional pillar. To be eligible for a service pension, women must have contributed for at least 35 years and 2 months, while men must have contributed for 38 years and 2 months.

The pension amount is calculated based on the national average salary, an individual coefficient based on the insured person’s income, and a coefficient related to the work incapacity category. As of July 1, 2023, the minimum monthly old-age pension amount was set at 307.07 BGN (approximately €157).

For individuals who have not contributed enough, a social pension is available from age 70, subject to means testing. The amount of this social pension is 276.64 BGN (approximately €141) per month since July 2023.

Unemployment Benefits

To receive unemployment benefits in Bulgaria, one must have at least 9 months of social insurance affiliation within the 15 months preceding the job loss. The benefit amount is calculated based on the insured person’s previous income, with a monthly cap of €1,200.

The daily allowance corresponds to 60% of the average daily salary over the last 24 months. The payment duration varies from 4 months to 1 year, depending on the length of prior contributions.

Medical Assistance

The Bulgarian healthcare system provides medical coverage to permanent residents, refugees, and persons under temporary protection. Foreigners with a long-term or permanent residence permit in Bulgaria are entitled to medical assistance subject to a user fee (€0.50 for retirees and approximately €1.50 for health insurance contributors).

EU nationals can receive emergency care by presenting their European Health Insurance Card. For foreigners on short stays, medical expenses are their responsibility, unless a specific international agreement applies.

Recent Reforms and Impact

Bulgaria has undertaken several reforms of its social protection system in recent years. A significant change was the introduction of a weighting system in the calculation of pensions from December 2021, taking into account the arduousness of jobs held during the career.

However, despite these efforts, over 800,000 Bulgarian retirees still live below the poverty line. The government has regularly increased minimum pension amounts, but benefit adequacy remains a major challenge.

Regional Comparison

Compared to other European countries, the level of social benefits in Bulgaria remains relatively low. For example, the amount of family allowances is significantly lower than that observed in countries like France or Germany.

However, Bulgaria has made significant progress in improving its social coverage, particularly by expanding access to healthcare and strengthening support measures for families. The country is gradually approaching European standards, although significant gaps remain.

Perception and Challenges

Citizens’ perception of the Bulgarian social protection system is mixed. Many appreciate the improvements made in recent years but feel that benefits remain insufficient given the cost of living. Social policy experts emphasize the need to continue strengthening the social safety net, especially for the most vulnerable groups.

The main challenges include improving benefit adequacy, reducing poverty among the elderly, and adapting the system to demographic changes. Bulgaria must also find a balance between expanding social coverage and the long-term financial sustainability of the system.
