How this calculator helps
What the calculator is for
The levies calculator helps self-employed people and employees with side business estimate income tax, social insurance, health insurance and net income after levies. It is useful for pricing, invoicing and planning cash flow.
How the calculation works
The calculation uses annual revenue, expense percentage, business type and selected tax reliefs or deductions. It estimates the tax base, income tax, social and health insurance and shows annual and monthly views.
Practical example
Example: if you invoice CZK 900,000 per year as a self-employed person and use 60% lump-sum expenses, the calculator estimates profit, levies and net amount after tax. Switching activity type shows the difference between main and side activity.
What to watch out for
Rules for minimum advances, thresholds, flat tax, deductions and reliefs may change. The result does not cover VAT or detailed accounting situations. For tax returns and official reports, verify the numbers with an accountant.
