Start with domestic law
First determine whether Germany treats you as tax resident and whether the income falls within German tax rules. The treaty then limits overlapping claims; it does not replace domestic filing.
Two main relief methods
Under exemption, Germany may exclude foreign income but use it to determine the rate on German income. Under credit, Germany taxes the income and credits qualifying foreign tax within limits.
- Country and treaty article.
- Income type and source.
- Foreign assessment and payment proof.
- Dates of residence and work.
Why payroll is not the final answer
Withholding by an employer or bank does not prove the final country entitlement. Cross-border cases are settled through returns, certificates and sometimes refund claims abroad.
Frequently asked
Does a tax treaty mean I file in only one country?
No. Filing duties can exist in both countries even when double taxation is relieved.
Is all foreign tax credited in Germany?
No. Credits are limited by the treaty, German law and the German tax attributable to that income.
Can exempt income raise my German tax rate?
Yes. Progression rules can affect the rate on income Germany may tax.
