1. The German tax map
| Topic | What it does | Start here |
|---|---|---|
| Lohnsteuer | Employer withholding from employment pay | Tax classes and salary calculator |
| Einkommensteuer | Annual tax on an individual’s taxable income | Tax return |
| Steuer-ID | Lifelong identifier for an individual | German Tax ID |
| Steuernummer / USt-IdNr | Identifiers for tax cases and VAT activity | Business tax numbers |
| Umsatzsteuer | VAT on qualifying supplies | Self-employed taxes |
| Gewerbesteuer | Municipal trade tax for qualifying Gewerbe | Self-employed taxes |
2. Employees: gross salary, withholding and tax class
Your employer withholds Lohnsteuer from gross pay using the electronic ELStAM data and your tax class. The class changes monthly withholding and cash flow; it does not create a separate final annual tax rate. Pension, health, unemployment and long-term care contributions also reduce net pay, but they are social insurance rather than income tax.
Use the one canonical gross-to-net calculator for an estimate, then read the tax-class guide for the payroll category and the salary guide for the deduction structure.

3. The annual tax return
Some people must file, while many straightforward employees can file voluntarily. A return brings together annual income and allowable deductions; the Finanzamt then issues a Steuerbescheid. ELSTER is the official filing portal.
Deadlines depend on the tax year, whether filing is mandatory and whether an adviser is involved. Use the tax-return guide for the current dated deadline facts rather than a timeless rule of thumb.

4. Steuer-ID is not the same as a business tax number
The BZSt assigns the personal Steuer-ID, normally for life. A Finanzamt can issue a Steuernummer for a tax case. A business may also need an USt-IdNr for VAT identification, particularly in qualifying EU transactions. Entering one identifier where another is requested causes avoidable delays.

5. Self-employed people and businesses
Individuals generally start from business profit, not revenue or a “freelance salary.” VAT, trade tax and company tax depend on the activity, legal form and transaction. Freiberufler and Gewerbe also follow different registration routes.
The cash-planning calculator deliberately asks you for tax and insurance reserve assumptions instead of pretending to calculate an individual assessment.
6. Use official tools for the final check
Third-party calculators are useful for planning, not for filing or payroll certification. Use the BMF calculator as an official cross-check and ELSTER for tax-administration forms. Seek a Steuerberater for international income, a company, VAT complexity, property income or material uncertainty.
