Employment vs Service Contract in Bulgaria: Which One Is Right for Your Business?

When hiring someone in Bulgaria, businesses often face a key question:

Employment contract or service (civil) contract?

At first glance, the difference seems simple. In reality, the choice has major implications for:

• taxes
• social security
• legal risk

Employment Contract: The Standard Model

This creates a classic employer-employee relationship.

The employer:

• sets working hours
• defines workplace
• controls the work process

The employee:

• follows company rules
• works under supervision

Provides:

• paid leave
• sick leave
• social security protection

Service Contract: A Different Logic

This is used for specific results, not ongoing work

Examples:

• design project
• consulting
• software development
• one-time services

No:

• fixed working hours
• internal hierarchy
• direct control

The Key Difference: Control

Employment:

• employer controls the process

Service contract:

• focus on the result
• contractor controls how work is done

This is critical during inspections.Tax and Social Security Differences

Employment:

• full social contributions
• administrative obligations

Service contract:

• different regime
• depends on circumstances

When to Use Each

Service Contract

• project-based work
• no fixed hours
• no team integration

Employment Contract

• ongoing work
• fixed structure
• part of the organization

Main Risk

Using a service contract for what is effectively employment may lead to:

• reclassification
• retroactive contributions
• penalties

Authorities assess actual working conditions, not just the contract.

How to Decide

Ask:

• Is the work ongoing or project-based?
• Are there fixed working hours?
• Is the person part of the team?
• Who controls the work?

Modern Reality: Flexible Work

Remote work and global hiring blur the lines. But this increases the need for correct structuring

Final Insight

Choosing the right contract is not just administrative.

It affects:

• tax exposure
• legal risk
• long-term stability

A well-structured workforce is a sign of a mature business.
