Bulgaria Salary Guide 2026: Flat 10% Income Tax and Social Contributions

June 2026 · 7 min read

Bulgaria stands out in the EU for having one of the most straightforward income tax systems: a flat 10% rate applied to almost all personal income. Combined with relatively low social security contributions and a lower cost of living than Western Europe, Bulgaria has attracted remote workers and entrepreneurs seeking to reduce their tax burden legally while remaining within the EU. This guide explains how the Bulgarian tax system works for employees in 2026.

The flat 10% income tax (ДДФЛ)

Bulgaria levies a single flat rate of 10% on personal income, under the Данък върху доходите на физическите лица (ДДФЛ). This rate applies to employment income after social security contributions are deducted. There are no progressive brackets and no high-rate bands for top earners.

The taxable base is: gross salary minus employee social security contributions. The 10% applies to this net figure.

Employee social security contributions

Bulgarian employees pay into three branches of the state social security system (НОИ). For 2026:

Branch Employee rate
State pension (NOI/ДОО)7.9%
Additional mandatory pension (ДЗПО/УПФ)2.8%
Health insurance (НЗОК)3.2%
Total employee SS13.9%

Social security contributions are subject to a monthly ceiling. For 2026, the maximum insurable monthly income is approximately BGN 3,400 (BGN 40,800 per year). Income above this ceiling is not subject to SS contributions but still subject to the 10% income tax.

Why Bulgaria attracts EU remote workers

With a flat 10% income tax, Bulgaria has the lowest personal income tax rate in the EU. Combined with employer contributions of roughly 17–18% on top of gross salary, Bulgaria's total labor cost is also one of the lowest in the bloc. For freelancers and self-employed individuals, an additional option is to register a EOOD (single-member LLC) and pay the 10% corporate tax rate on company profits rather than the personal income tax rate.
