What is the income tax rate in Bulgaria in 2025?

Bulgaria applies a flat personal income tax rate of 10% in 2025. This is a genuine flat rate — the same percentage applies regardless of income level, unlike progressive systems with multiple brackets.

How do I calculate income tax in Bulgaria?

Multiply your gross income by 0.1 (10%). For example, a gross salary of лв 1000 results in лв 100.00 in income tax and a net take-home of лв 900.00. Note that social contributions are not included.

Does the 10% flat tax include social security contributions?

No. The 10% rate covers personal income tax only. Bulgaria levies social security, health insurance, and other contributions separately on top of this. Your actual net pay will be lower than this calculator shows.

Is my data sent anywhere when I use this calculator?

No. All income tax calculations run entirely in your browser using JavaScript. No salary figures, inputs, or personal data are ever transmitted to any server.
