Germany taxes residents on their worldwide income through the Einkommensteuer, collected for most employees as monthly Lohnsteuer (wage tax) withheld by their employer. Many workers are taxed automatically and are not required to file, but submitting a return through the ELSTER portal often recovers over-withheld amounts. Self-employed people and higher earners generally must file.
Germany's income tax system can feel dense to newcomers, with its wage-tax withholding, six tax classes, and progressive rates. This guide explains the core mechanics in plain language so you understand who pays, how it is collected, and how the annual return works. For figures that change each year — rates, brackets, and allowances — confirm the current numbers directly with the German tax authority.
Who pays income tax in Germany?
If you are resident in Germany, you are generally taxed on your worldwide income; non-residents are taxed on German-source income only. Income tax (Einkommensteuer) applies to wages, self-employment earnings, business profits, rental income, and most investment income. For employees, the tax is collected throughout the year as Lohnsteuer — wage tax that your employer withholds from each paycheck and remits to the Finanzamt (local tax office) on your behalf. The two are the same tax; only the method of collection differs.
The system is progressive, meaning the rate rises with income, and a tax-free basic allowance (Grundfreibetrag) shields a baseline amount of earnings. Because these thresholds are revised periodically, always check the figures for the relevant year with the authority.
What are the German tax classes (Steuerklassen)?
Germany assigns employees to one of six tax classes, which determine how much wage tax your employer withholds each month. They do not change your final yearly liability — that is settled when you file — but they affect your monthly take-home pay.
- Class I: single, divorced, or widowed.
- Class II: qualifying single parents (with lone-parent relief).
- Class III: the higher-earning spouse in a married couple (paired with Class V).
- Class IV: married couples where both earn similar amounts.
- Class V: the lower-earning spouse (paired with Class III).
- Class VI: a second or third job, with the highest withholding and no allowances.
Married couples can often choose between combinations (such as III/V or IV/IV) to balance monthly withholding, though the annual return reconciles any difference either way.
How do you file a German tax return?
The annual income tax return (Einkommensteuererklärung) is filed online through ELSTER (elster.de), the German tax authority's free electronic filing portal. You will need your tax identification number (Steuer-ID). Employees with only straightforward salary income are frequently not obligated to file, but doing so voluntarily commonly results in a refund because deductions — commuting costs, work expenses, insurance contributions, and more — are claimed on the return rather than automatically.
Filing becomes mandatory in certain situations, such as having significant additional income, multiple employers, or when the Finanzamt requests a return. If your situation is complex — self-employment, foreign income, or rental property — many residents engage a licensed Steuerberater (a regulated tax professional) for help.
When are German tax returns due?
For a mandatory return, the standard deadline is several months after the close of the tax year, with an extension available when a registered Steuerberater files on your behalf. Voluntary returns can typically be submitted for several prior years. Because exact dates shift and are occasionally adjusted, confirm the current deadline with the Finanzamt or on the official ELSTER portal before you file.
Where to get help
Income tax in Germany rewards a little preparation: know your tax class, keep records of deductible expenses, and file through ELSTER to reconcile what was withheld. For complex circumstances, professional help can save time and prevent errors. You can find recognized professional bodies for Germany to locate a qualified Steuerberater or comparable resource.
