What the calculator compares

For freelance profession it models:

• Normative expense deduction (NPR) — 25%, 40%, or 60% by activity type
• Income tax — 10% on taxable income
• Social insurance — DOO (14.8%), health (ZO, 8%), supplementary pension (DZPO, 5%) on your chosen insurance income

For EOOD it models:

• Corporate tax — 10% on accounting profit (here: gross income without separate expense lines)
• Dividend tax — 5% when profit is distributed
• Manager social insurance — same insurance base as freelance for a fair comparison

Results show net income, total burden, and effective rate for both structures.

Input fields — step by step

1. Annual gross income (BGN)

Enter expected or actual annual turnover. The calculator does not split invoiced vs collected amounts — use the figure you plan with.

2. Activity / NPR rate

Button	NPR	Examples
25%	General activity	IT consultants, designers, marketers
40%	Liberal profession	Doctors, lawyers, accountants, engineers
60%	Artistic work	Artists, musicians, actors

Pick the rate that matches your main registered activity in BULSTAT. Wrong NPR choice is a common planning mistake.

3. Insurance income (BGN/month)

For 2026 the minimum is 933 BGN, maximum 3750 BGN per month. Higher base means higher contributions and higher future pension rights.

4. Months active

Usually 12. If you started mid-year, enter the actual number of active months.

Reading the results

• Net income — what remains after taxes and insurance (for EOOD: after corporate tax, dividend tax, and manager insurance).
• Effective rate — total burden as a share of gross income.
• Comparison line — which structure leaves more net with the same inputs.

Remember: EOOD also has accounting, capital, banking, and admin costs that the calculator does not include.
