How this estimate works
Step-by-step
- Pick the year and filing status. For married couples, the tool applies income splitting (halve income → compute tax → double).
- Enter taxable income. Use income after allowances (e.g., Grundfreibetrag) and typical deductions.
- Estimate income tax (ESt). A stepped progression approximates the official formula.
- Apply SolZ and church tax. SolZ phases in when income tax passes a threshold; church tax is a % of income tax.
