Bulgaria continues to apply a 10% corporate income tax rate — among the lowest in the EU.

Terminating employment in Bulgaria is not just about having a valid reason. It is about following the correct legal procedure.

If you employ staff in Bulgaria — or are planning to — it is important to understand how termination works in practice.
