Bulgaria has quietly become one of the more attractive hiring destinations in Eastern Europe. It carries a flat 10% income tax rate, a well-educated workforce, and EU membership that simplifies cross-border employment for foreign companies. But that low headline rate can be misleading if you don’t account for the full range of employer contributions sitting on top of gross salary. This guide walks you through every mandatory cost so you can budget accurately before you hire.
How employer taxes work in bulgaria
Bulgaria uses a payroll system where both employer contributions and employee deductions are calculated on the employee’s gross salary. As the employer, you’re responsible for two things: paying your own mandatory social security contributions on top of gross salary, and withholding the correct income tax and employee-side social contributions before paying the net amount to the employee.
Payroll runs on a monthly cycle. Wages must be paid by the 5th of the following month, and all contributions are remitted to the National Revenue Agency and the National Social Security Institute on the same schedule.
One administrative note for 2026: Bulgaria adopted the euro (EUR) as its official currency on January 1, 2026, with a fixed conversion rate of 1 EUR = 1.95583 BGN. You may still encounter figures quoted in Bulgarian lev (BGN) during the transition period, so it’s worth being comfortable with both.
Social security contributions
Employer social security contributions in Bulgaria sit between 18.92% and 19.62% of gross salary, depending on the industry risk classification assigned to your business. Here’s how that breaks down.
Pension and social insurance
The largest single contribution is the pension fund component, at 7.66% of gross salary. On top of that, you’ll pay 2.8% into the Additional Mandatory Social Security scheme, which provides supplementary pension coverage through a capital-based fund.
Sickness, maternity, and unemployment
You contribute 2.1% toward sickness and maternity coverage, and 0.6% toward unemployment insurance. These funds cover benefit payments to employees during illness, parental leave, and periods of involuntary unemployment.
Accident insurance
Accident and occupational disease insurance ranges from 0.4% to 1.1%, depending on the risk category assigned to your industry. Higher-risk industries (manufacturing, construction, logistics) attract rates at the upper end of the range. Office-based and professional services firms typically fall at the lower end.
Health insurance
You’ll also contribute 4.8% of gross salary toward the National Health Insurance Fund. This runs separately from the social security contributions above.
Income tax withholding
Bulgaria’s flat income tax rate of 10% is one of the lowest in the EU, and it applies uniformly regardless of salary level. There’s no progressive scale or higher rate for higher earners.
As the employer, you withhold this tax from the employee’s gross salary each month and remit it directly to the National Revenue Agency. You don’t pay this amount yourself; it comes out of the employee’s earnings. But you are responsible for the accurate calculation and timely submission.
Employee social security deductions
In addition to income tax, you withhold the employee’s share of social security contributions. These are separate from your own employer contributions and are also funded from the employee’s gross salary:
| Contribution | Employee rate |
|---|---|
| Social Security (pension) | 6.58% |
| Common Diseases and Maternity Fund | 1.40% |
| Unemployment Fund | 0.40% |
| Supplementary Mandatory Pensions | 2.20% |
| Health Insurance | 3.20% |
| Total employee deductions | ~13.78% |
Combined with the 10% income tax, total employee-side deductions come to roughly 23.78% of gross salary. When presenting compensation packages to candidates, it’s helpful to be upfront about take-home pay so expectations are aligned before an offer is made.
The seniority bonus
Bulgaria’s Labour Code requires employers to pay a seniority bonus, formally known as an additional remuneration for acquired professional experience and length of service. This isn’t discretionary.
The minimum rate is 0.6% of the employee’s base salary per year of professional experience. Importantly, “professional experience” isn’t limited to their tenure with your company. It includes relevant experience from previous employers in the same or similar roles. If you’re hiring someone with ten years of relevant experience, you’re immediately on the hook for an additional 6% of base salary from day one of employment.
The seniority bonus must be written into the employment contract. It’s calculated and paid monthly as part of regular payroll. There’s no cap on the number of years that count, and no mechanism to exclude prior experience, so factor this into your salary modelling before extending an offer.
Total employer cost
Here’s a simple illustration of the full cost for an employee earning the minimum wage of BGN 1,213/month (approximately €620):
| Cost component | Rate | Monthly amount (BGN) |
|---|---|---|
| Gross salary | 1,213.00 | |
| Pension (employer) | 7.66% | 92.92 |
| Additional Mandatory Social Security | 2.80% | 33.96 |
| Sickness and Maternity | 2.10% | 25.47 |
| Unemployment Insurance | 0.60% | 7.28 |
| Accident Insurance | 0.40%–1.10% | 4.85–13.34 |
| Health Insurance | 4.80% | 58.22 |
| Total employer cost | ~1,431–1,444 BGN |
That represents a roughly 18–19% premium above gross salary at minimum wage. At higher salary levels, the absolute cost rises proportionally since contributions are percentage-based, though the accident insurance range remains fixed by industry.
Annual bonuses are not legally mandated in Bulgaria. There’s no statutory 13th month salary. Any annual or performance-based bonus is only required if you’ve committed to it in the employment contract or a company policy document, so make sure your contract language reflects exactly what you intend.
How an EOR simplifies bulgarian payroll compliance
If you’re hiring in Bulgaria without a registered legal entity there, you can’t run payroll directly under Bulgarian law. You’d typically need to set up a local subsidiary, which involves registration, local accounting infrastructure, and ongoing compliance obligations with the National Revenue Agency and National Social Security Institute.
An Employer of Record (EOR) removes that requirement entirely. The EOR employs your worker on your behalf under a compliant Bulgarian employment contract, handles all payroll calculations, withholds the correct income tax and employee social security deductions, and remits both employer and employee contributions to the relevant Bulgarian authorities.
This matters particularly in Bulgaria because of the seniority bonus obligation. An EOR that understands Bulgarian labour law will verify a candidate’s prior relevant experience, calculate the correct additional remuneration from the start, and ensure the employment contract meets all statutory requirements. Getting this wrong from day one creates retroactive liability.
For companies that already work with independent contractors in Bulgaria and are considering converting them to employees, the EOR model makes that transition straightforward without requiring entity setup.
If you want to explore the full range of options, RemotePass offers EOR services across multiple countries, including Bulgaria, with built-in payroll compliance and contract management.
Getting started
Bulgaria’s low flat income tax and EU membership make it a compelling hire destination for foreign companies. The employer contribution burden is moderate but real, and the seniority bonus adds a layer of complexity that catches many first-time Bulgarian employers off guard.
