bulgaria self employed tax calculator

How this Bulgaria self employed tax calculator works

This tool gives a practical estimate for freelancers and self-insured professionals in Bulgaria. It follows the common structure: revenue → deductible expenses → social contributions → personal income tax. The goal is to help you forecast cash flow, set better prices, and avoid year-end tax surprises.

Core assumptions used

• Flat personal income tax is entered as a percentage (default: 10%).
• Social contributions are based on a monthly insurable base that you choose.
• You can model either actual expenses or normative expense percentages (25% / 40%).
• Mandatory social contributions are treated as deductible before calculating income tax.
• Advance tax paid reduces the remaining income tax due.

Bulgarian self-employed tax basics (simplified)

1) Taxable income starts from your revenue

You begin with annual gross revenue. Then you reduce it either by documented business expenses or by normative expenses where applicable. The result is your pre-social taxable base.

2) Social and health contributions matter a lot

For many self-insured people, social contributions are computed from a selected monthly insurable income (within legal limits set yearly). This calculator lets you enter a monthly base and a combined contribution rate so you can adapt the estimate to your exact status.

3) Income tax is applied after deductible contributions

After deductible expenses and social contributions, income tax is calculated on the remaining tax base. If you already made advance tax payments during the year, those are subtracted from final tax due.

Step-by-step usage guide

• Enter your expected annual gross revenue in BGN.
• Select your expense method (actual or normative 25%/40%).
• Set months active and monthly social insurance base.
• Confirm contribution and tax rates.
• Click Calculate to see liability, effective rate, and estimated net income.

Example scenarios

Consultant using actual expenses

Suppose revenue is 60,000 BGN and real business costs are 12,000 BGN. With 12 months active, a 1,200 BGN insurable base, and 27.8% social rate, the calculator shows your estimated annual social burden, income tax, and net income after both.

Freelancer using normative expenses

If you switch to normative 25%, tax-deductible expenses are fixed as a percentage of revenue. This can simplify accounting and sometimes improve tax efficiency, depending on your real costs. In this mode, the calculator displays net income after taxes and contributions, but before unknown real operating costs.

Common mistakes to avoid

• Using the wrong expense method for your legal category.
• Forgetting to include months where activity still generated contribution obligations.
• Ignoring advance payments and only checking tax at year-end.
• Mixing VAT cash flow with income tax calculations.
• Assuming one rate applies forever—rules and thresholds can change annually.
