How this calculation works
This calculator is designed to show what changes under each Poland tax regime instead of using one fake flat percentage.
- If you choose VAT registered, the calculator first removes 23% VAT from the entered annual income.
- Your selected expense ratio is used to estimate real cash expenses and profit.
- For progressive and flat tax, income tax is estimated from profit after the simplified ZUS social estimate.
- For progressive tax, the calculator uses the 30,000 PLN tax-free amount, 12% up to 120,000 PLN and 32% above that.
- For flat tax, the calculator uses a 19% rate on the estimated tax base.
- For lump sum mode, tax is calculated from revenue, not profit. The expense model still affects displayed net cash, but not the lump-sum tax itself.
- Health insurance is estimated according to the chosen regime, including the 2026 minimum rules and fixed ryczałt thresholds.
This is still a simplified estimate. It does not include Mały ZUS Plus, ulga na start, all ryczałt rates by activity, IP Box, or every Polish deduction and exception.
