The Shape of Employment Cost
What a role costs an employer is not the gross salary. What follows is not a set of numbers but a map of the items that make up the cost — take current values from the competent authority.
What Total Cost Is Made Of
Employer cost has three layers: the gross salary, the employer's share of social security and health insurance contributions, and the ancillary obligations arising from the employment relationship (paid leave provision, occupational health services, accident and occupational disease cover). A company that budgets on gross salary alone discovers the second and third layers later. Rates and upper limits are set afresh each year; for current values the Национална агенция за приходите (НАП) and the Национален осигурителен институт (НОИ) are the only valid sources.
The Contribution Base and Ceiling
Contributions are not applied directly to the gross salary; they are calculated within a statutory range between a minimum and a maximum insurable income. How that range is set for a given year is redetermined annually by the state social insurance budget act. In budgeting terms this means the same gross salary can produce a different employer cost in different years. Calculate the real contribution burden for a role from that year's act and the НОИ guidance issued for it — do not carry last year's table forward.
How Contract Type Changes the Cost
Open-ended employment contracts, fixed-term contracts, management contracts and service contracts with self-employed individuals sit under different contribution and termination regimes. The real exposure here is not cost but reclassification: a relationship that is in substance dependent employment may be treated as an employment contract on inspection, whatever the contract is called. That boundary is enforced by the Изпълнителна агенция "Главна инспекция по труда" (ИА ГИТ); settle the model with a local employment lawyer.
Where to Look When Budgeting
Three sources are enough for a comparable budget: the НСИ wage series by sector and region, the НОИ insurable income range for the relevant year, and the НАП calendar of employer obligations. The picture is consistent only when all three come from the same year; figures assembled across different years look coherent and produce the wrong answer. For final confirmation, work with a local accountant — payroll and contribution filing is a distinct specialism in Bulgaria.
