The calculation runs only in your browser. Nothing is sent to us or stored.
How it is calculated
- Taxable income = profit − deductions. Other income, allowances and lump sums are not taken into account.
- Income tax follows the 2026 tariff under § 32a EStG (basic tax-free allowance, Grundfreibetrag, €12,348), with the splitting method for joint assessment.
- Solidarity surcharge: 5.5% of the income tax, but only above the exemption limit and with a phase-in zone.
Frequently asked questions
When do I have to pay the income tax?
After the tax return, with the tax assessment notice. The tax office often also sets quarterly prepayments (10 March, 10 June, 10 September, 10 December).
How much should I set aside?
A good rule of thumb is the reserve from the calculator – plus the VAT you collect and have to pay to the tax office.
Is the result binding?
No. It is an estimate for one person with income from self-employment. The actual tax depends on all your income and deductions.
