How Tax is Calculated (Simple!)
Bulgarian tax calculation is straightforward: gross income minus social contributions minus small deductions equals taxable income. Taxable income × 10% = tax due. Employers withhold monthly. Annual return reconciles. Much simpler than progressive systems with multiple brackets.
Calculate Gross Income
Sum all income: salary, bonuses, business profit, rental income, foreign income (if resident). Bulgarian residents include worldwide income. Non-residents only Bulgarian sources.
Subtract Social Contributions
Deduct 13.78% social security and health contributions from gross salary. Self-employed calculate separately. Get income after social contributions.
Apply Any Deductions
Subtract voluntary pension contributions (up to 10%), life insurance premiums (up to 10%), donations (up to 65%). Most people have minimal deductions. System designed to be simple.
Calculate Tax at 10%
Multiply taxable income by 10%. That's it! No brackets, no complexity. Someone with €25,000 of taxable income pays €2,500 tax (assuming no deductions). Simple mathematics.
Annual Reconciliation
Employer withholds tax monthly. File annual return by April 30 (or March 31 online for 5% discount). Reconcile actual vs. withheld. Refund if overpaid, payment if underpaid.
Example Calculation (€18,000 annual salary, €1,500/month)
Bulgaria adopted the euro on January 1, 2026 (1 EUR = 1.95583 BGN), so all amounts are in euros. Tax rates stayed the same. Example includes voluntary 10% pension contribution for deduction demonstration.
